    The influence of grain size on Tl was analysed in poly minerals extracted from Mexican spices as Origanum vulgare L. (oregano) y Capsicum annun (chile guajillo). The poly minerals size were selected by Zimmerman method up to 10 {mu}m and exposed to 0.5-10 kGy range from {sup 60}Co. The glow curves were centered at 166 C for Capsicum annun and at 126 C for Origanum vulgare l. In both cases was observed at 5 kGy a weak saturation for Tl response. This behaviour is attributed to feldspar and quartz are present in the samples and this results is in agreement with other european spices obtained. For >10 {mu}m particle size the Tl response increased respect to the doses, and it is possible that increase the organic impurities quantities are present in the samples and contributed to the Tl when the samples were thermally excited. The aim of this work is provide more ideas with regard to the behaviour of luminescence emission as dependent of the size particle in the irradiated spices. The methodology might useful for quality control also in radiation processing. (Author)

  5. Spice allergy.

    Chen, James L; Bahna, Sami L

    2011-09-01

    To provide a review on spice allergy and its implementation in clinical practice. PubMed searches were performed using spice allergy as the keyword for original and review articles. Selected references were also procured from the reviewed articles' references list. Articles were selected based on their relevance to the topic. Spices are available in a large variety and are widely used, often as blends. Spice allergy seems to be rare, reportedly affecting between 4 and 13 of 10,000 adults and occurring more often in women because of cosmetic use. No figures were available on children. Most spice allergens are degraded by digestion; therefore, IgE sensitization is mostly through inhalation of cross-reacting pollens, particularly mugwort and birch. The symptoms are more likely to be respiratory when exposure is by inhalation and cutaneous if by contact. Studies on skin testing and specific IgE assays are limited and showed low reliability. The diagnosis primarily depends on a good history taking and confirmation with oral challenge. The common use of spice blends makes identifying the particular offending component difficult, particularly because their components are inconsistent. Spices are widely used and contain multiple allergens, yet spice allergy is probably markedly underdiagnosed. There is a need for reliable skin testing extracts and serum specific IgE assays. Currently, the diagnosis depends on a good history taking and well-designed titrated challenge testing. Until immunotherapy becomes developed, treatment is strict avoidance, which may be difficult because of incomplete or vague labeling.

  8. MER SPICE Interface

    Sayfi, Elias

    2004-01-01

    MER SPICE Interface is a software module for use in conjunction with the Mars Exploration Rover (MER) mission and the SPICE software system of the Navigation and Ancillary Information Facility (NAIF) at NASA's Jet Propulsion Laboratory. (SPICE is used to acquire, record, and disseminate engineering, navigational, and other ancillary data describing circumstances under which data were acquired by spaceborne scientific instruments.) Given a Spacecraft Clock value, MER SPICE Interface extracts MER-specific data from SPICE kernels (essentially, raw data files) and calculates values for Planet Day Number, Local Solar Longitude, Local Solar Elevation, Local Solar Azimuth, and Local Solar Time (UTC). MER SPICE Interface was adapted from a subroutine, denoted m98SpiceIF written by Payam Zamani, that was intended to calculate SPICE values for the Mars Polar Lander. The main difference between MER SPICE Interface and m98SpiceIf is that MER SPICE Interface does not explicitly call CHRONOS, a time-conversion program that is part of a library of utility subprograms within SPICE. Instead, MER SPICE Interface mimics some portions of the CHRONOS code, the advantage being that it executes much faster and can efficiently be called from a pipeline of events in a parallel processing environment.

  12. Examining Mars with SPICE

    Acton, Charles H.; Bachman, Nathaniel J.; Bytof, Jeff A.; Semenov, Boris V.; Taber, William; Turner, F. Scott; Wright, Edward D.

    1999-01-01

    The International Mars Conference highlights the wealth of scientific data now and soon to be acquired from an international armada of Mars-bound robotic spacecraft. Underlying the planning and interpretation of these scientific observations around and upon Mars are ancillary data and associated software needed to deal with trajectories or locations, instrument pointing, timing and Mars cartographic models. The NASA planetary community has adopted the SPICE system of ancillary data standards and allied tools to fill the need for consistent, reliable access to these basic data and a near limitless range of derived parameters. After substantial rapid growth in its formative years, the SPICE system continues to evolve today to meet new needs and improve ease of use. Adaptations to handle landers and rovers were prototyped on the Mars pathfinder mission and will next be used on Mars '01-'05. Incorporation of new methods to readily handle non-inertial reference frames has vastly extended the capability and simplified many computations. A translation of the SPICE Toolkit software suite to the C language has just been announced. To further support cartographic calculations associated with Mars exploration the SPICE developers at JPL have recently been asked by NASA to work with cartographers to develop standards and allied software for storing and accessing control net and shape model data sets; these will be highly integrated with existing SPICE components. NASA specifically supports the widest possible utilization of SPICE capabilities throughout the international space science community. With NASA backing the Russian Space Agency and Russian Academy of Science adopted the SPICE standards for the Mars 96 mission. The SPICE ephemeris component will shortly become the international standard for agencies using the Deep Space Network. U.S. and European scientists hope that ESA will employ SPICE standards on the Mars Express mission. SPICE is an open set of standards, and

  14. Irradiation of spices and herbs

    Eiss, M.I.

    1983-01-01

    Gamma irradiation has been extensively studied as a means of reducing the microbial contamination of spices. Experiments indicate that spices, with water contents of 4.5-12%, are very resistant to physical or chemical change when irradiated. Since spices are used primarily as food flavoring agents, their flavor integrity must not be changed by the process. Sensory and food applications analysis indicate no significant difference between irradiated samples and controls for all spices tested

    1982-07-01

    An experiment has been done to determine the effect of irradiation and reduction of moisture content on the keeping quality of commercial spices, i.e. nutmeg (Myristica fragrans), black and white pepper (Piper ningrum). The results showed that a dose of 5 kGy could reduce the microbial load of spices as much as 2-4 log cycles for the total plate count and 1-3 log cycles for the total mould and yeast counts. The microbial reduction due to the irradiation treatment was found to be lower in more humid products. Prolonged storage enhanced the microbial reduction.

    Full Text Available From 01 January 2017 you enter the interstate standard GOST 33271-2015 “Dry Spices, herbs and vegetable seasonings. Manual exposure in order to combat pathogens and other microorganisms” which States that the absorbed dose of radiation to the spices should be from 3 to 30 kGy. The study found that before the introduction of permissive legislative framework in the consumer market of Russia there are irradiated food products (chili, ground chili, ground spicy chili, black pepper. For radiation monitoring of food safety, we used the method of electron paramagnetic resonance (EPR, which allows quickly and with a high degree of reliability to establish the fact of irradiation. It is established that all samples of spices irradiated with dose of 12 kGy (technology radappertization gave typical spectra of the signals established by the method of electron paramagnetic resonance in the domestic EPR spectrometer, the intensity, amplitude and peak width of the EPR signal of samples of spices with the increase of irradiation dose increases. It is proven that repeated exposure no effect accumulation. Integration with 2017 Russia in the global practi ce of using radiation technologies of processing of food products and food raw materials with the purpose of extending shelf life confirms the need for a data Bank on the radiation sensitivity of various food products to determine the optimal doses and the eff ect of radiation doses on the shelf life and quality of products.

  1. Spice and the World

    Yu Xin

    2017-01-01

    Around 1500 , the world experi ̄enced an explosion of exploration which greatly transformed the world for the next several hundreds of years. During this time, Christopher Columbus, Vasco da Gama, and other seafaring entrepreneurs sought new routes to India’s Malabar Coast and the Indonesian archipelago. The objective of their ef ̄forts was mainly spice specifically pepper, cinna ̄mon, nutmeg, clove, and a few others. In the en ̄suing years, the Spanish, Portuguese, English, and Dutch would all seek to dominate the spice trade, employing an astonishing amount of blood ̄shed and brutality to achieve their aims. They were undermined only by pirates, who would occasional ̄ly plunder the spice boats, relieving them of their precious cargo. The reason behind their desire to seek spice, was not only, and in fact, not even primarily, profits. In an age that poured its commercial ener ̄gies into such un - poetical ends such as arms, oil, and mineral ores, the drive to obtain anything quite so quaintly insignificant as spice must strike us today as mystifying indeed. While historians of ̄ten point to medieval Europe’s problems with ran ̄cid meat, along with the mind -numbing repeti ̄tiveness of its diet, as the source of spice’s early popularity, the main reason for desiring spice came down to one simple thing: mystery. Spices were, in a sense, magical if not divine, arriving by un ̄known means from the vast blank spaces on the map, spaces populated by dragons, gods, and monsters. From mystery grew mystique. It was a seductive premise. This article starts by examining the rise of Europe’s economy after the first millennium and the subsequent demand for Eastern luxuries. Ginger, mace, and other exotic ingredients quickly became status symbols among noblemen—not unlike furs or jewels—as well as staples in upper -class kitch ̄ens, with nearly every dish deluged by seasonings, to the point where the medieval appetite for spice looked less like a taste

  4. Subthreshold SPICE Model Optimization

    Lum, Gregory; Au, Henry; Neff, Joseph; Bozeman, Eric; Kamin, Nick; Shimabukuro, Randy

    2011-04-01

    The first step in integrated circuit design is the simulation of said design in software to verify proper functionally and design requirements. Properties of the process are provided by fabrication foundries in the form of SPICE models. These SPICE models contain the electrical data and physical properties of the basic circuit elements. A limitation of these models is that the data collected by the foundry only accurately model the saturation region. This is fine for most users, but when operating devices in the subthreshold region they are inadequate for accurate simulation results. This is why optimizing the current SPICE models to characterize the subthreshold region is so important. In order to accurately simulate this region of operation, MOSFETs of varying widths and lengths are fabricated and the electrical test data is collected. From the data collected the parameters of the model files are optimized through parameter extraction rather than curve fitting. With the completed optimized models the circuit designer is able to simulate circuit designs for the sub threshold region accurately.

  5. Spices, irradiation and detection methods

    Sjoeberg, A.M.; Manninen, M.

    1991-01-01

    This paper is about microbiological aspects of spices and microbiological methods to detect irradiated food. The proposed method is a combination of the Direct Epifluorescence Filter Technique (DEFT) and the Aerobic Plate Count (APC). The evidence for irradiation of spices is based on the demonstration of a higher DEFT count than the APC. The principle was first tested in our earlier investigation in the detection of irradiation of whole spices. The combined DEFT+APC procedure was found to give a fairly reliable indication of whether or not a whole spice sample had been irradiated. The results are given (8 figs, 22 refs)

  8. Spice In Martian Soil

    Seiferlin, K.; Spohn, T.; Spice Team

    The Netlander mission offers a unique opportunity to study the surface and the inte- rior of Mars at four different locations at the same time. In addition to real "network"- science, where the presence of four stations is a 'must' to address global science as- pects, local, landing site-related instruments can more than double our knowledge of the surface of Mars, compared to the three landing sites (Viking 1 and 2, Pathfinder) we are currently familiar with. The SPICE instrument will characterize the soil at the landing sites. Force sensors integrated into the seismometer legs (three per station) will determine the mechanical strength of the soil. Thermal sensors will measure the local soil temperature, the thermal inertia and the thermal diffusivity independently, thus allowing us to determine the thermal conductivity and the volumetric heat capac- ity of the soil. These properties will tell us about (1) soil cementation ("duricrust"), (2) volatile exchange with the atmosphere, (3) grain size, (4) near-surface stratigra- phy, and (5) will finally provide ground truth for remote sensing data such as that from Mars Global Surveyor's thermal emission spectrometer.

  11. Spectrophotometric analysis of irradiated spices

    Josimovic, L; Cudina, I

    1987-01-01

    Seven different spices (thyme, cinnamon, coriander, caraway, pimento, paprika, black pepper) were treated by gamma radiation at an absorbed dose of 10 kGy, and the effect on chemical quality was determined. The effects of this dose were assessed by spectrophotometric analysis of some water-soluble constituents of spices (carbohydrates; carbonyl compounds) and on the content of water-insoluble steam-volatile oils. The colour of paprika and the content of piperine in pepper held in different packaging materials were measured in unirradiated and irradiated samples as a function of storage time. In all cases irradiation does not bring about any distinct qualitative or quantitative chemical changes based on spectrophotometric analysis of spice extracts.

  12. Irradiation of spices - a review

    Sadecka, J.

    2007-01-01

    Food irradiation is a process of exposing food to ionising radiation such as gamma rays emitted from the radioisotopes 60Co and 137Cs, or high energy electrons and X-rays produced by machine sources. The use of ionising radiation to destroy harmful biological organisms in food is considered a safe, well proven process that has found many applications. Depending on the absorbed dose of radiation, various effects can be achieved resulting in reduced storage losses, extended shelf life and/or improved microbiological and parasitological safety of foods. The most common irradiated commercial products are spices and vegetable seasonings. Spice irradiation is increasingly recognised as a method that reduces post-harvest losses, ensures hygienic quality, and facilitates trade with food products. This article reviews recent activities concerning food irradiation, focusing on the irradiation of spices and dried vegetable seasonings from the food safety aspect

    Jessica Elizabeth, De La Torre; Gassara, Fatma; Kouassi, Anne Patricia; Brar, Satinder Kaur; Belkacemi, Khaled

    2017-04-13

    Spices are parts of plants that due to their properties are used as colorants, preservatives, or medicine. The uses of spices have been known since long time, and the interest in the potential of spices is remarkable due to the chemical compounds contained in spices, such as phenylpropanoids, terpenes, flavonoids, and anthocyanins. Spices, such as cumin (cuminaldehyde), clove (eugenol), and cinnamon (cinnamaldehyde) among others, are known and studied for their antimicrobial and antioxidant properties due to their main chemical compounds. These spices have the potential to be used as preservatives in many foods namely in processed meat to replace chemical preservatives. Main chemical compounds in spices also confer other properties providing a variety of applications to spices, such as insecticidal, medicines, colorants, and natural flavoring. Spices provide beneficial effects, such as antioxidant activity levels that are comparable to regular chemical antioxidants used so they can be used as a natural alternative to synthetic preservatives. In this review, the main characteristics of spices will be described as well as their chemical properties, different applications of these spices, and the advantages and disadvantages of their use.

  18. Detection of irradiated spices by thermoluminescence analysis

    Hammerton, K.M.; Banos, C.

    1996-01-01

    Spices are used extensively in prepared foods. The high levels of contamination of many spices with microorganisms poses a problem for the food industry. Irradiation treatment is the most effective means of reducing the microbial load to safe levels. Although the process is currently subject to a moratorium in Australia, it is used in several countries for the decontamination of spices. Methods for detecting irradiation treatment of spices are necessary to enforce compliance with labelling requirements or with a prohibition on the sale of irradiated foods. Thermoluminescence (TL) analysis of spice samples has been shown to be an applicable method for the detection of all irradiated spices. It was established that the TL response originates from the adhering mineral dust in the sample. Definitive identification of many irradiated spices requires the separation of a mineral extract from the organic fraction of the spice sample. This separation can be achieved by using density centrifugation with a heavy liquid, sodium polytungstate. Clear discrimination between untreated and irradiated spice samples has been obtained by re-irradiation of the mineral extract after the first TL analysis with an absorbed dose of about 1 kGy (normalisation). The ratio of the first to second TL response was about one for irradiated samples and well below one for untreated samples. These methods have been investigated with a range of spices to establish the most suitable method for routine control purposes. (author)

  19. Mexican Revolution

    It was the complex and far-reaching transformation of the Mexican Revolution rather than the First World War that left its mark on Mexican history in the second decade of the 20th century. Nevertheless, although the country maintained its neutrality in the international conflict, it was a hidden theatre of war. Between 1914 and 1918, state actors in Germany, Great Britain and the United States defined their policies towards Mexico and its nationalist revolution with a view not only to improve...

    Nair, P.M.; Padwal Desai, S.R.; Sharma, A.; Gholap, A.S.; Behere, A.G.; Parte, M.N.; Jadhav, S.

    1996-01-01

    Decontamination by gamma irradiation of minor spices such as coriander, fennel, cumin, aniseed, cardamom (large) and ajowan was studied. The bacterial load on these spices ranged from 10 2 - 10 5 cfu/g, while the fungal load ranged from 10-10 3 cfu/g. No microorganisms were detected in samples exposed to radiation and stored up to 12 mo. Though pathogens, such as coliforms, B. cereus and Staphylococci were detected in some samples of spices, their presence was not detected in spices exposed to radiation. A comparison of gas liquid chromatographic profiles indicated no significant change in the quality of volatile oils of these spices. Intra country transportation studies, in collaboration with two national laboratories and a multinational corporation, confirmed our earlier observations regarding retention of quality in several spices following irradiation, transport and storage. Similar results were evident from intercountry collaborative studies with Japan. (author). 10 refs, 6 figs, 10 tabs

  1. Effects of irradiation upon spices

    1978-04-01

    ESR studies were performed on untreated and irradiated samples of paprika powder, ground black pepper, and a spice mixture of the following composition: paprika, 55%; black pepper, 14%; allspice, 9%; coriander, 9%; marjoram, 7%; cumin, 4%; and nutmeg, 2%. Gamma radiation doses from 0.5 to 5 Mrad were applied. In the case of paprika samples, the effect of moisture content on the formation and disappearance of radiation-induced free radicals was also investigated. Shortly after irradiation (on the day of radiation treatment) high amounts of free radicals were detected in irradiated spice samples but they diminished upon storage. After a period of 3 months the ESR signals of the irradiated samples approximated those of the controls. The free radicals found in unirradiated ground spices did not disappear during a storage period as long as one year. The formation and disappearance of radiation-induced free radicals were found to be strongly affected by the moisture content of samples. If a sample of low moisture content containing a high free radical concentration after irradiation was placed in an atmosphere of higher moisture content, the free radicals decayed rapidly.

    The cell-count-reducing effect of ionizing radiations is well known. To reduce microbiological contamination in the most frequently used spices, ground paprika, black pepper and a mixture of seven spices, a radiation dose of 1.5 Mrad (15 kGy) was applied. The aim of the investigation was to find out whether this dose caused significant changes in the spices which could be detected by thermal analysis. The results unambiguously show that the applied dose does not cause significant changes detectable by thermal analysis. This finding supports earlier experiences according to which no structural changes, disadvantageously influencing utilization of radiation treated spices, are caused by similar or smaller doses.

    The spoilage of spices is generally due to microbial contamination as well as development of off-favours due to oxidation of oils. This research was conducted to investigate the influence of irradiation doses (2-10 KGy) on bacterial and fungal contamination as well as col colour and volatile components during storage of spices. The influence of different gamma radiation doses on total mould count of spices such as turmeric, coriander, chilies, cumin and black pepper, was determined and the results are presented. The effect of irradiation on total bacterial counts of these spices is presented. The dose of 10 KGy decreased the bacterial counts to either undetectable or very low levels in various spices.

    An experiment has been carried out to evaluate the quality of irradiated spices packaged in some indigenous packaging materials. Spices used were whole nutmeg (myristica fragrans) and whole white pepper (piper nigrum). The spice samples were packaged in tin containers with or without oxygen absorber and in woven polypropylene (PP) bags, then irradiated at 5 kGy, and despatched from Jakarta to Wagenigen by sea-freight. The shipment was performed in small and commercial size packages. The results showed that irradiation treatment could effectively disinfest and decontaminate spices without altering their chemical composition and sensory properties. PP bags, particularly the one without inner liner, were unable to withstand rough handling and to prevent reinfestation during shipment. Tin containers were able to withstand rough handling and prevent reinfestation. The oxygen absorber used had no effect on microbial count and other parameters of the spices. (author)

    In this study, possible methods for detecting irradiation of spices are reviewed. Of the different kinds of techniques, the most promising control methods are thermo‐ and chemiluminescence and the microbiological and viscosimetric methods. The suitability of analytical methods for detecting possible degradation of the main compounds in the aromas of spices during irradiation is also discussed. The irradiation of spices can be detected reliably with thermoluminescence and by chemiluminescence measurements. Advantages of a new thermoluminescence method, based on mineral measurements, are also presented. Spices and their microbial contents and decontamination are discussed. Combined use of the direct epifluorescent filter technique (DEFT) and the aerobic plate count method (APC) is possibly a suitable method for detecting the irradiation of spices. Also, viscosity measurements combined with luminometric methods have been considered as possible detection methods

  15. Spice phenolics inhibit human PMNL 5-lipoxygenase.

    Prasad, N Satya; Raghavendra, R; Lokesh, B R; Naidu, K Akhilender

    2004-06-01

    A wide variety of phenolic compounds and flavonoids present in spices possess potent antioxidant, antimutagenic and anticarcinogenic activities. We examined whether 5-lipoxygenase (5-LO), the key enzyme involved in biosynthesis of leukotrienes is a possible target for the spices. Effect of aqueous extracts of turmeric, cloves, pepper, chili, cinnamon, onion and also their respective active principles viz., curcumin, eugenol, piperine, capsaicin, cinnamaldehyde, quercetin, and allyl sulfide were tested on human PMNL 5-LO activity by spectrophotomeric and HPLC methods. The formation of 5-LO product 5-HETE was significantly inhibited in a concentration-dependent manner with IC(50) values of 0.122-1.44 mg for aqueous extracts of spices and 25-83 microM for active principles, respectively. The order of inhibitory activity was of quercetin>eugenol>curcumin>cinnamaldehyde>piperine>capsaicin>allyl sulfide. Quercetin, eugenol and curcumin with one or more phenolic ring and methoxy groups in their structure showed high inhibitory effect, while the non-phenolic spice principle allyl sulfide showed least inhibitory effect on 5-LO. The inhibitory effect of quercetin, curcumin and eugenol was similar to that of synthetic 5-LO inhibitors-phenidone and NDGA. Moreover, the inhibitory potency of aqueous extracts of spice correlated with the active principles of their respective spices. The synergistic or antagonistic effect of mixtures of spice active principles and spice extracts were investigated and all the combinations of spice active principles/extracts exerted synergistic effect in inhibiting 5-LO activity. These findings clearly suggest that phenolic compounds present in spices might have physiological role in modulating 5-LO pathway.

    2017-02-15

    Diabetes mellitus (DM) remains a major health care problem worldwide both in developing and developed countries. Many factors, including age, obesity, sex, and diet, are involved in the etiology of DM. Nowadays, drug and dietetic therapies are the two major approaches used for prevention and control of DM. Compared to drug therapy, a resurgence of interest in using diet to manage and treat DM has emerged in recent years. Conventional dietary methods to treat DM include the use of culinary herbs and/or spices. Spices have long been known for their antioxidant, anti-inflammatory, and anti-diabetic properties. This review explores the anti-diabetic properties of commonly used spices, such as cinnamon, ginger, turmeric, and cumin, and the use of these spices for prevention and management of diabetes and associated complications.

    Spices have been widely used as food flavorings and folk medicines for thousands of years. Numerous studies have documented the antioxidant, anti-inflammatory and immunomodulatory effects of spices, which might be related to prevention and treatment of several cancers, including lung, liver, breast, stomach, colorectum, cervix, and prostate cancers. Several spices are potential sources for prevention and treatment of cancers, such as Curcuma longa (tumeric), Nigella sativa (black cumin), Zingiber officinale (ginger), Allium sativum (garlic), Crocus sativus (saffron), Piper nigrum (black pepper) and Capsicum annum (chili pepper), which contained several important bioactive compounds, such as curcumin, thymoquinone, piperine and capsaicin. The main mechanisms of action include inducing apoptosis, inhibiting proliferation, migration and invasion of tumors, and sensitizing tumors to radiotherapy and chemotherapy. This review summarized recent studies on some spices for prevention and treatment of cancers, and special attention was paid to bioactive components and mechanisms of action.

  4. Medieval European medicine and Asian spices.

    Nam, Jong Kuk

    2014-08-01

    This article aimed to explain the reasons why Asian spices including pepper, ginger, and cinnamon were considered as special and valuable drugs with curative powers in the Medieval Europe. Among these spices, pepper was most widely and frequently used as medicine according to medieval medical textbooks. We analyzed three main pharmacology books written during the Middle Ages. One of the main reasons that oriental spices were widely used as medicine was due to the particular medieval medical system fundamentally based on the humoral theory invented by Hippocrates and Galen. This theory was modified by Arab physicians and imported to Europe during the Middle Ages. According to this theory, health is determined by the balance of the following four humors which compose the human body: blood, yellow bile, black bile, and phlegm. Each humor has its own qualities such as cold, hot, wet, and dry. Humoral imbalance was one of the main causes of disease, so it was important to have humoral equilibrium. Asian spices with hot and dry qualities were used to balance the cold and wet European diet. The analysis of several major medical textbooks of the Middle Ages proves that most of the oriental spices with hot and dry qualities were employed to cure diverse diseases, particularly those caused by coldness and humidity. However, it should be noted that the oriental spices were considered to be much more valuable and effective as medicines than the local medicinal ingredients, which were not only easily procured but also were relatively cheap. Europeans mystified oriental spices, with the belief that they have marvelous and mysterious healing powers. Such mystification was related to the terrestrial Paradise. They believed that the oriental spices were grown in Paradise which was located in the Far East and were brought to the Earthly world along the four rivers flowing from the Paradise.

  5. Assessing intake of spices by pattern of spice use, frequency of consumption and portion size of spices consumed from routinely prepared dishes in southern India.

    2015-01-11

    Measurement of dietary intake of spices is gaining significance because of recognition of their health promoting benefits as well as its use for risk assessment of contaminant exposures. Estimating intake of spices at the individual level, presents several challenges since various spices are used as an integrated part of a prepared food and consumed in amounts much smaller than other dietary components. The objective of the present study is to assess intake of spices at the household and individual level on the basis of pattern of spice use and portion size of spice consumed from routinely prepared dishes in Hyderabad city in Southern India. The study was conducted in 100 households in urban areas of Hyderabad city in India with the help of a spice intake questionnaire that was prepared to collect information on the pattern of spice use, frequency, and quantity of spice consumption of 17 spices routinely used in Indian cuisine. The quantity of spice intake was assessed by measuring portion size of spice consumed from the quantity of i) spices added in routinely prepared dishes and ii) the prepared dish consumed by an individual. Based on the type of dish prepared and frequency of preparing the dishes, 11 out of 17 spices were found to be consumed by more than 50% of the households. Maximum number of spices was consumed at weekly frequencies. Red chillies and turmeric were the most frequently consumed spices by 100% of the households. The mean total intake of spices was observed to be higher through dishes consumed daily (10.4 g/portion) than from those consumed at weekly or monthly frequencies. Highest portion size intake was observed for chillies (mean 3.0 g; range 0.05-20.2 g) and lowest for nutmeg (mean 0.14 g; range 0.02-0.64 g) and mace (mean 0.21 g; range: 0.02-0.6 g). The study suggested that assessment of intake of spices varies with frequency of use of spices and type of dish consumed. Portion size estimations of spices consumed and the frequency of

    Natural spices are commonly used by the people in Nigeria. They may be easily contaminated with heavy metals when they are dried and then pose a health risk for the consumers. The aim of this study was to determine the levels of heavy metals in some commonly consumed natural spices namely Prosopis Africana, Xylopia aethiopica, Piper gineense, Monodora myristica, Monodora tenuifolia and Capsicum frutescens sold in the local markets of Awka, Anambra state, South East Nigeria to estimate the potential health risk. The range of heavy metal concentration was in the order: Zn (14.09 - 161.04) > Fe (28.15 - 134.59) > Pb (2.61 - 8.97) > Cr (0.001 - 3.81) > Co (0.28 - 3.07) > Ni (0.34 - 2.89). Pb, Fe and Zn exceeded the maximum allowable concentrations for spices. The Target Hazard Quotient (THQ) of the spices varied from 0.06-0.5. Estimated daily intakes (EDI) were all below the tolerable daily intake (TDI). The lead levels in Prosopis africana, Xylopia aethiopica, Piper gineense, Monodora myristica and Capsicum frutescens which are 8-30 times higher than the WHO/FAO permissible limit of 0.3 mg/kg. Lead contamination of spices sold in Awka (south east Nigeria) may add to the body burden of lead. A good quality control for herbal food is important in order to protect consumers from contamination. food products, spices, potential toxic metals, risk assessment, public health.

  9. Antimicrobial functions of spices: why some like it hot.

    Billing, J; Sherman, P W

    1998-03-01

    Although spices have been important for centuries in food preparation throughout the world, patterns of spice use differ considerably among cultures and countries. What factors underlie these differences? Why are spices used at all? To investigate these questions, we quantified the frequency of use of 43 spices in the meat-based cuisines of the 36 countries for which we could locate traditional cookbooks. A total of 4578 recipes from 93 cookbooks was analysed. We also complied information on the temperature and precipitation in each country, the ranges of spice plants, and the antibacterial properties of each spice. These data were used to investigate the hypothesis that spices inhibit or kill food-spoilage microorganisms. In support of this is the fact that spice plant secondary compounds are powerful antimicrobial (i.e., antibacterial and antifungal) agents. As mean annual temperatures (an indicator of relative spoilage rates of unrefrigerated foods) increased, the proportion of recipes containing spices, number of spices per recipe, total number of spices used, and use of the most potent antibacterial spices all increased, both within and among countries. Likewise, the estimated fraction of bacterial species inhibited per recipe in each country was positively correlated with annual temperature. Several alternative hypotheses were considered--that spices provide macronutrients, disguise the taste and smell of spoiled foods, or increase perspiration and thus evaporative cooling; it also is conceivable that spice use provides no benefits. However, none of these four alternatives was well supported by our data. The proximate reason spices are used obviously is to enhance food palatability. But the ultimate reason is most likely that spices help cleanse foods of pathogens and thereby contribute to the health, longevity and reproductive success of people who find their flavors enjoyable.

    2001-01-01

    Some spices (cumin, coriander, black pepper and red pepper), commonly used due to their specific aroma and nutritional value were studied using chemiluminescence (CL) method to test whether the food has been irradiated or not. The spices were ground to different mesh sizes and subjected to gamma ray doses of 2.5, 5.0, 7.5 and 10 Kgy. The effect of radiation doses and particle size on the CL response of irradiated and un-irradiated samples was checked using luminol and lucigenin sensitizers. The storage experiment was also performed for all spices with both the sensitizers in order to pick the suitable sensitizer for CL study. During this study Co-60 gamma ray source and Bio-orbit 1250 luminometer were used after precise calibration

    1994-01-01

    Decontamination of spices (onion powder, cardamom, red pepper powder, etc.) used for special types of Bulgarian sausages was investigated. Gamma irradiation ( 60 Co) at doses of 4, 6, 8 and 10 kGy was applied. It was found that the total count of microorganisms in spices was between 1.85.10 5 and 3.8.10 7 . The largest was the amount of the coliforms and the staphylococci in the onion powder. The cardamom and onion powder were free of coliforms with dose of 4 kGy. The staphylococci were eliminated with doses of 6 kGy. The number of proteolytic microorganisms was decreased but they were isolated from spices irradiated even with 10 kGy. (author)

    Effect of gamma irradiation (8 kGy) on decontamination of pre packed (in polyethylene) and unpacked spices such as black pepper and chilli, was studied over a storage period of 12 months. Radiation dose of 8.0 kGyu completely decontaminated by the spices. Fungal packaged samples. Water content increased from a range values of 7.6-8.5% to 11.4 to 15.2% the increase was higher in red chilli than black pepper. Colour values significantly changed during storage, however the influence of radiation was not consistent. (author)

  16. Lead and cadmium content of spices

    Bielig, H J; Dreyer, H; Askar, A

    1977-02-02

    The lead and cadmium content of various spices was determined by flameless atomic absorption (AAS). With the exception of one sample, the lead content was lower than 5 ppm, averaging a value of 2,2 ppm Pb. Thus, the maximum permissible level of 5 ppm Pb as recommended by different DIN standards, is not exceeded. The cadmium content was - except for one sample - lower than 0,5 ppm averaging a value of 0,23 ppm Cd. It can be assumed, that by spicing our dishes, the ingestion of lead and cadmium stays at a low level.

  17. Genotoxicity test of irradiated spice mixture by dominant lethal test

    Barna, J

    1986-03-01

    Dominant lethal test (DLT) was performed in Sprague Dawley male rats prefed with 25% irradiated spice mixture which was composed of 55% non-pungent ground paprika, 14% black pepper, 9% allspice, 9% coriander, 7% marjoram, 4% cumin, 2% nutmeg. Microbial count of the spice mixture was reduced with 15 kGy from a sup(60)Co source. Control groups received spice-free or untreated spice diet or were administered to cyclophosphamide i.p., respectively. DTL parameters altered significantly in the latter group but neither untreated nor irradiated spice mixture proved to be germ cell mutagens. 24 refs.; 8 figs.

    2016-01-01

    For the spices used in curry dishes and the spices used except for curry dishes, the effects of irradiation sterilization and conventional superheated-steam sterilization were compared with sensory test. As for spices, superheated-steam sterilization reduces aroma and changes color tone compared with irradiation sterilization. Even with cooked curry, radiologically sterilized products were stronger in 'flavor before sample tasting' or 'spicy taste during sample tasting' with statistically significant difference compared with superheated-steam sterilized products. As for the comparison with spices themselves, red pepper and white/black pepper tended to be stronger in taste and pungent taste than radiologically sterilized products. In addition, superheated-steam sterilized products of red hot pepper and turmeric were very different in color from untreated products, while radiologically sterilized products showed a little difference. When comparing color and flavor in a 2D map, it was found at a glance that the radiologically sterilized product was close to the untreated product. Thia map can easily convince the merit of irradiation sterilization, and it was found to be effective for promoting risk communication. In the case of white pepper, the radiologically sterilized product showed more strong pungent than the superheated-steam sterilized product with statistically significant difference. However, not only the strength difference but also qualitative difference was perceived in flavor. (A.O.)

  19. Implementation of interconnect simulation tools in spice

    Satsangi, H.; Schutt-Aine, J. E.

    1993-01-01

    Accurate computer simulation of high speed digital computer circuits and communication circuits requires a multimode approach to simulate both the devices and the interconnects between devices. Classical circuit analysis algorithms (lumped parameter) are needed for circuit devices and the network formed by the interconnected devices. The interconnects, however, have to be modeled as transmission lines which incorporate electromagnetic field analysis. An approach to writing a multimode simulator is to take an existing software package which performs either lumped parameter analysis or field analysis and add the missing type of analysis routines to the package. In this work a traditionally lumped parameter simulator, SPICE, is modified so that it will perform lossy transmission line analysis using a different model approach. Modifying SPICE3E2 or any other large software package is not a trivial task. An understanding of the programming conventions used, simulation software, and simulation algorithms is required. This thesis was written to clarify the procedure for installing a device into SPICE3E2. The installation of three devices is documented and the installations of the first two provide a foundation for installation of the lossy line which is the third device. The details of discussions are specific to SPICE, but the concepts will be helpful when performing installations into other circuit analysis packages.

    Full Text Available El objetivo del presente trabajo es caracterizar la relación interpersonal entre cuidadores informales primarios y adultos mayores en situación de dependencia, a partir, de un estudio de casos múltiples. Se empleó la metodología cualitativa y el método etnometodológico. Se seleccionaron tres casos, por la presencia de diferentes grados de dependencia en los adultos mayores. Las técnicas empleadas fueron: entrevista en profundidad, escala de evaluación funcional y la observación abierta.Los principales resultados muestran que las relaciones interpersonales entre un cuidador informal primario y un adulto mayor en situación de dependencia, actualizan la historia de la relación anterior, generando vivencias de frustración y/o satisfacción en función de la dinámica pasada. Este proceso primario adquiere más trascendencia que las propias habilidades comunicativas en la relación y marcan una vivencia de la relación, que en algunos casos, se diferencia de la vivencia de la labor del cuidado.

    Full Text Available Los estados mexicanos ubicados en la frontera norte de México enfrentan una evolución económica y demográfica que contrasta con el resto del país. En este artículo pruebo la hipótesis de que tales diferencias hacen que las haciendas públicas estatales fronterizas muestren un menor grado de dependencia en las participaciones federales en comparación con el resto de los estados mexicanos. Para demostrar tal hipótesis, propongo y estimo dos modelos de regresión lineal para explicar las variaciones en el grado de dependencia financiera estatal, empleando una base de datos que combina series de tiempo anuales (de 1993 a 1999 para 31 estados mexicanos. Los resultados muestran evidencia de que las entidades fronterizas tienen un menor grado de dependencia en comparación con las del resto del país.

  5. Quality control and disinfestation of spices for export

    George, C.K.

    1998-01-01

    India is the largest producer, consumer and exporter of spices in the world. Other than a few, all spices are grown in this country. The production is estimated at 2.6 million tonnes with an export of about 0.22 million tonnes valued around US $ 333 million. India's share in the world trade is over 40 % in quantity and 20 % in value. Many spices produced in India face quality problems as in other countries. For identifying quality produce, grade specifications have been introduced for all the important spices. With the liberalization of government controls, compulsory pre-shipment inspection has been withdrawn unless insisted by the buyer abroad. To meet the sanitary and phytosanitary requirements, the Spices Board has taken up a massive programme for upgradation of quality of Indian spices. Logo mark and Spice House Certificates are awarded to those spice exporting units having necessary infrastructure for assuring quality. By now, 6 units have been accredited to ISO 9000. Though different chemical and non-chemical treatments are available for improving hygienic quality, irradiation appears to be a reliable method. However, its wide application in the spice industry depends upon the conviction of the consumers of its safety. Because of the comprehensive programmes taken up for quality improvement of spices, India is confident of exporting spices meeting quality specifications prescribed by the importing countries.

  6. Spices: Therapeutic Potential in Cardiovascular Health.

    Rastogi, Subha; Pandey, Madan Mohan; Rawat, Ajay Kumar Singh

    2017-01-01

    Dietary factors play a key role in the development as well as prevention of certain human diseases, including cardiovascular diseases. Currently there has been an increase in global interest to identify medicinal plants that are pharmacologically effective and have low or no side effects for use in preventive medicine. Culinary herbs and spices are an important part of human nutrition in all the cultures of the world. There is a growing amount of literature concerning the potential benefits of these herbs and spices from a health perspective especially in conferring protection against cardiovascular diseases. The objective of this review is to provide information on the recent scientific findings on some common spices that have a distinct place in folk medicine in several of the Asian countries as well as on their traditional uses for the role they can play in the management of heart diseases and which may be useful in defining cost effective and inexpensive interventions for the prevention and control of CVDs. Systematic literature searches were carried out and the available information on various medicinal plants traditionally used for cardiovascular disorders was collected via electronic search (using Pubmed, SciFinder, Scirus, GoogleScholar, JCCC@INSTIRC and Web of Science) and a library search for articles published in peerreviewed journals. No restrictions regarding the language of publication were imposed. This article highlights the recent scientific findings on four common spices viz. Greater cardamom (Amomum subulatum Roxb.), Coriander (Coriandrum sativum L.), Turmeric (Curcuma longa L.) and Ginger (Zingiber officinale Roscoe), for the role they can play in the management of heart diseases. Although they have been used by many cultures since ancient times and have been known to exhibit several medicinal properties, current research shows that they can also be effectively used for the prevention and control of CVDs.

    2015-05-01

    Phenolic compounds in spices were reportedly found to possess high antioxidant capacities (AOCs), which may prevent or reduce risk of human diseases such as cardiovascular disease, cancer and diabetes. The potential AOC of Chinese five-spice powder (consist of Szechuan pepper, fennel seed, cinnamon, star anise and clove) with varying proportion of individual spice ingredients was investigated through four standard methods. Our results suggest that clove is the major contributor to the AOC of the five-spice powder whereas the other four ingredients contribute to the flavour. For example, the total phenolic content as well as ferric reducing antioxidant power (FRAP), Trolox equivalent antioxidant capacity (TEAC) and oxygen radical absorbance capacity (ORAC) values increased linearly with the clove percentage in five-spice powder. This observation opens the door to use clove in other spice mixtures to increase their AOC and flavour. Moreover, linear relationships were also observed between AOC and the total phenolic content of the 32 tested spice samples.

  9. Mycotoxins in spices and herbs-An update.

    Kabak, Bulent; Dobson, Alan D W

    2017-01-02

    Spices and herbs have been used since ancient times as flavor and aroma enhancers, colorants, preservatives, and traditional medicines. There are more than 30 spices and herbs of global economic and culinary importance. Among the spices, black pepper, capsicums, cumin, cinnamon, nutmeg, ginger, turmeric, saffron, coriander, cloves, dill, mint, thyme, sesame seed, mustard seed, and curry powder are the most popular spices worldwide. In addition to their culinary uses, a number of functional properties of aromatic herbs and spices are also well described in the scientific literature. However, spices and herbs cultivated mainly in tropic and subtropic areas can be exposed to contamination with toxigenic fungi and subsequently mycotoxins. This review provides an overview on the mycotoxin risk in widely consumed spices and aromatic herbs.

  10. SPICE: An innovative, flexible instrument concept

    Nishioka, Kenji; Cauffman, D. P.; Jurcevich, B.; Mendez, David J.; Ryder, James T.

    1994-01-01

    Studies and plans for orbital capture of cosmic dust and interplanetary dust particles (IDP's) looked very bright with the advent of space station Freedom (SSF) and formal selection of Cosmic Dust Collection Facility (CDCF) as an attached payload in 1990. Unfortunately it has been downhill since its selection, culminating in CDCF being dropped as attached payload in the SSF redesign process this year. This action was without any input from the science or cosmic dust communities. The Exobiology Intact Capture Experiment (Exo-ICE) as an experiment on CDCF was also lost. Without CDCF, no facility-class instrument for cosmic dust studies is available or planned. When CDCF (and Exo-ICE) was selected as a SSF attached payload, an exercise called the small particle intact capture experiment (SPICE) was started for Exo-ICE to develop an understanding and early testing of the necessary expertise and technology for intact capture of cosmic dust and IDP's. This SPICE activity looks to fly small, meter square or less, collection area experiments on early orbital platforms of opportunity such as EURECA, MIR, WESTAR, and others, including the shuttle. The SPICE activity has focused on developing techniques and instrument concepts to capture particles intact and without inadvertent contamination. It began with a survey and screening of available capture media concepts and then focused on the development of a capture medium that can meet these requirements. Evaluation and development of the chosen capture medium, aerogel (a silicon oxide gel), has so far lived up to the expectations of meeting the requirements and is highlighted in a companion paper at this workshop. Others such as McDonnell's Timeband Capture Cell Experiment (TICCE) on EuReCa and Tsuo's GAS-CAN lid experiments on STS 47 and 57 have flown aerogel, but without addressing the contamination issue/requirement, especially regarding organics.

    2012-06-01

    Full Text Available The aim of this paper is to report the findings of the study of the routes and the distance traveled by spices from the farming location to the consumer in traditional and organised retailing. This research study is primarily exploratory in nature, and the research instruments include interviews and survey through questionnaires with players in the spice supply chain. The study is to track the spice routes by the retailers for assessing the current state of the supply chain management practices, and evaluate ‘food mileage’ clocked by them. ‘Food miles’ is a relatively recent concept in retailing and result of this study reveals that significant increase in food miles in the case of organised retailers. Longer food miles of spices are an indicator of the shift towards organised retailing. The speed at which spices reach their destination as well as the time taken between any two points was not observed. This is the limitation of this study, and also the scope for further research. The research study is not aimed at finding the factors related to the food mileage.

  14. Antibacterial and Antifungal Activities of Spices

    Liu, Qing; Meng, Xiao; Li, Ya; Zhao, Cai-Ning; Tang, Guo-Yi; Li, Hua-Bin

    2017-01-01

    Infectious diseases caused by pathogens and food poisoning caused by spoilage microorganisms are threatening human health all over the world. The efficacies of some antimicrobial agents, which are currently used to extend shelf-life and increase the safety of food products in food industry and to inhibit disease-causing microorganisms in medicine, have been weakened by microbial resistance. Therefore, new antimicrobial agents that could overcome this resistance need to be discovered. Many spices—such as clove, oregano, thyme, cinnamon, and cumin—possessed significant antibacterial and antifungal activities against food spoilage bacteria like Bacillus subtilis and Pseudomonas fluorescens, pathogens like Staphylococcus aureus and Vibrio parahaemolyticus, harmful fungi like Aspergillus flavus, even antibiotic resistant microorganisms such as methicillin resistant Staphylococcus aureus. Therefore, spices have a great potential to be developed as new and safe antimicrobial agents. This review summarizes scientific studies on the antibacterial and antifungal activities of several spices and their derivatives. PMID:28621716

  15. The Roman and Islamic spice trade: New archaeological evidence.

    Van der Veen, Marijke; Morales, Jacob

    2015-06-05

    Tropical spices have long been utilized in traditional medicine and cuisine. New archaeological evidence highlights temporal changes in the nature and scale of the ancient spice trade and in the ancient usage of these plants. Furthermore, a study of their 'materiality' highlights that the impact of spices extends beyond their material properties. Here the botanical remains of spices recovered from archaeological excavations at a port active in the Roman and medieval Islamic spice trade are evaluated. Recent excavations at Quseir al-Qadim, an ancient port located on the Red Sea coast of Egypt, have provided new evidence for the spice trade. Due to the arid conditions ancient botanical remains were preserved in abundance and these included spices, as well as a wide range of other food plants. Quseir al-Qadim was active as a transport hub during both the Roman and Islamic periods (ca. AD 1-250, known as Myos Hormos, and again during ca. AD 1050-1500, known as Kusayr), and the remains thus facilitate a study of temporal change in the trade and usage of these spices. Standard archaeobotanical methods were used to recover, identify and analyze these remains. At least seven tropical spices were recovered from the excavations, as well as several other tropical imports, including black pepper (Piper nigrum), ginger (Zingiber officinale), cardamom (Elettaria cardamomum), turmeric (Curcuma sp.), fagara (cf. Tetradium ruticarpum), myrobalan (Terminalia bellirica and Terminalia chebula) and betelnut (Areca catechu). A marked contrast between the two chronological periods in the range of spices recovered points to changes in the nature and scale of the trade between the Roman and medieval Islamic periods, while differences in the contexts from which they were recovered help to identify temporal changes in the way in which the spices were utilized during those periods. Archaeological and textual evidence suggest that in antiquity spices were used in ritual (funeral rites

  17. Comparative study of thermoluminescence detection methods for irradiated spices

    Kawamura, Y.; Kojima, K.; Sugita, T.; Yamada, T.; Saito, Y.

    1995-01-01

    The thermoluminescence (TL) detection methods for irradiated spices were compared using spice samples obtained on the Japanese market, irradiated at doses of 1, 5, 10 and 30 kGy and stored for 1 year before analysis. The TL intensities of irradiated spices were stable for 1 year after irradiation. Measurement with whole samples failed to identify irradiated samples. Minerals were separated from spices in sodium tungstate saturated solution and/or sodium polytungstate solution. The TL intensity of minerals which had undergone irradiation was significantly increased for all samples. However, the ranges of TL intensity of irradiated and unirradiated samples overlapped. Clear discrimination has been obtained between the TL ratios of irradiated and unirradiated spices by using normalized measurement with reirradiation. The detection limit in terms of irradiation dose is 1 kGy even in a sample that has been irradiated 1 year prior to analysis. Normalization is the best technique currently available for thermoluminescence analysis to identify irradiated spices

    Throughout history, the approach towards imported spices varied from culture to culture. In medieval and early post-medieval Europe, where spices became an exotic object of temporary desire, they were often used unskillfully and in a haphazard manner. In the Ottoman Constantinople, unlike in Europe, it was the moderate use of spices, and not overdosing them, that became a manifestation of status. As deliberate paragons of refinement, the Ottomans depreciated what they considered uncivilized w...

  2. Crisis de los cuidados, Ley de Dependencia y confusión semántica

    Serrano Pascual, Amparo

    2013-12-01

    Full Text Available The condition of dependence, inherent to all human being, has been regulated politically and institutionally on the basis of a series of assumptions which articulate a gender construction of care. These a priori’s could be subject to an overhaul due to the implementation of political initiatives, such as the Dependency Act as it could induce to a socialization of moral duties with regard to dependency, a visibility of competences and skills required for care and a review of the “gender” of work. This article debates, from a gender perspective, the potential of this Act and its contribution to the fight for giving a meaning to care. This analysis is based on field work, consisting of 20 in-depth interviews with key persons, with the view to study the semantic battles between the various players which participated in the elaboration of the Act.La condición de dependencia, inmanente a todo ser humano, ha sido regulada política e institucionalmente en base a una serie de supuestos incuestionables que articulan una construcción sexualizada de los cuidados. Estos a priori podrían verse revisados con la implementación de iniciativas políticas como la Ley 39/2006, de 14 de diciembre, de Promoción de la Autonomía Personal y Atención a las personas en situación de Dependencia (Ley de Dependencia o LAAD al poderse inducir una socialización de las obligaciones morales frente a la dependencia, una visibilización de las competencias y destrezas que reclaman los cuidados, y una revisión del “sexo” del trabajo. Este artículo discute, desde una perspectiva de género, el potencial herético de esta Ley y su contribución a una pugna por el sentido acerca de los cuidados. Para ello, este análisis crítico de la LAAD se apoya además en un trabajo de campo consistente en la realización de 20 entrevistas a informantes clave, con el que se trata de indagar en las luchas por el sentido entre diversos actores que participaron en la elaboraci

  6. Sterilization of ground spices by electron beams irradiation

    Hashigiwa, Masayuki; Nakachi, Ayako; Kobayashi, Hiroshi

    1999-01-01

    Each ground spice (Black Pepper, Turmeric, Ginger, Paprika and Basil), which was packaged into polyethylene film, was irradiated by electron beams at 5 different levels: 2, 4, 6, 8 and 10 kGy. Bacteriological tests for total bacterial count were carried out on spices before and after irradiation, but the tests for microfiora were carried out only before irradiation. Total bacterial count decreased in proportion to the level of electron beams. But the decreasing rate for Turmeric, Ginger and Basil was lower compared with that of other spices. The reason seems that rate of contamination by B. pumilus, which is thought as radiation resistant bacteria, was higher on these spices. (author)

    Both major and minor Indian spices and their blends were found to have significant high level of bacterial and fungal load. Radiation processing at 10 kGy dose was found to be effective for hygienization of spices and condiments without affecting their flavor and other quality attributes. Inter and Intra country transportation studies confirmed the retention of spice quality following irradiation, transportation and storage. A safe storage period was also determined for sambar powder packaged in metallised laminate pouch, which turned out to be 20 months under ambient storage conditions. Some spices were also found to have radioprotective effect. (author)

  9. Detection of irradiated spices by different physical techniques

    Chabane, S.; Pouliquen-Sonaglia, I.; Raffi, J.

    2001-01-01

    We used thermoluminescence, electron spin resonance, and viscosimetric measurements to establish whether or not a spice had been irradiated. Thermoluminescence, using the 1788 EN official protocol with an alternative method for the extraction of mineral impurities, led to proof of irradiation or proof of no treatment. Electron spin resonance led to different spectrum shapes depending on the chemical composition of the spices; ESR could only be used as proof of irradiation up to several weeks after irradiation, and only for some spices. Viscosimetric measurements carried out on spice suspensions led to a presumption of treatment (or of no treatment) and possibly to of of irradiation. (author)

  10. Detection of enzyme activity in decontaminated spices of industrial use

    Müller, R.; Theobald, R.

    1995-01-01

    A range of decontaminated spices of industrial use have been examinated for their enzymes (catalase, peroxidase, amylase, lipase activity). The genuine enzymes remain fully active in irradiated spices, whereas the microbial load is clearly reduced. In contrast steam treated spices no longer demonstrate enzyme activities. Steam treatment offers e.g. black pepper without lipase activity, which can no longer cause fat deterioration. Low microbial load in combination with clearly detectable enzyme activity in spices is an indication for irradiation, whereas, reduced microbial contamination combined with enzyme inactivation indicate steam treatment of raw material [de

  16. Emerging Trends in Microwave Processing of Spices and Herbs.

    Rahath Kubra, Ismail; Kumar, Devender; Jagan Mohan Rao, Lingamallu

    2016-10-02

    Today, spices are integral part of our food as they provide sensory attributes such as aroma, color, flavour and taste to food. Further their antimicrobial, antioxidant, pharmaceutical and nutritional properties are also well known. Since spices are seasonal so their availability can be extended year round by adopting different preservation techniques. Drying and extraction are most important methods for preservation and value addition to spices. There are different techniques for drying of spices with their own advantages and limitations. A novel, non-conventional technique for drying of spices is use of microwave radiation. This technique proved to be very rapid, and also provide a good quality product. Similarly, there are a number of non-conventional extraction methods in use that are all, in principle, solid-liquid extractions but which introduce some form of additional energy to the process in order to facilitate the transfer of analytes from sample to solvent. This paper reviews latest advances in the use of microwave energy for drying of spices and herbs. Also, the review describes the potential application of microwave energy for extraction of essential oil/bioactive components from spices and herbs and the advantages of microwave-assisted process over the other extraction processes generally employed for extraction. It also showcases some recent research results on microwave drying/extraction from spices and herbs.

  19. The use of spices in the production of traditional cheeses

    Renata Josipović

    2016-01-01

    Full Text Available Cheese is a highly valued dairy product worldwide, with a special focus on traditional cheeses, not only for their basic nutritive purposes but also as a part of the culture and characteristics of a certain country. Owing to the geographical location as well as the climate and vegetation diversity, in certain regions of Croatia the production of various traditional cheeses using spices was developed. Spices are either added to the cheese curd which is then formed, or cheese is wrapped into plant leaves. Sometimes spices are also applied onto the surface of the cheese, and only in rare cases spices are added into the curd. Spices added to cheese improve sensory characteristics, increase the stability and shelf life but also increase the nutritional value. The chemical composition of spices is very complex and every spice has a specific and dominant ingredient that contributes to the flavour of the product and/or its antimicrobial and antioxidant activity. This paper provides an overview of spices and aromatic herbs as natural preservatives that are used in the production of traditional cheeses.

  3. Effect of radiation on volatile component in spices

    Ratnayake, A.K.

    1991-01-01

    This research project deals with the determination of chemical changes of some spices such as Cardamon, Nutmeg, Clove and Pepper, when subjected to gamma irradiation. The spices were irradiated in a CO 6 0 gamma source with 5 kGy, 7kGy and 10 kGy at a dose rate of 5 kGy/hr. Radiation dose less than 10 kGy can be used for processing of spices, without producing any changes in volatile components. The disadvantages in using the traditional methods of fumigation, use of chemicals or heat treatment as a measure of reducing contamination are discussed. It is shown that irradiation is the best method of decontamination of spices without making changes in oil percentage or chemical composition. Finally the study discusses the economic aspects and authorization from the point of view of consumer acceptance and the use of irradiation of spices

    Full Text Available El presente trabajo tiene como objetivo describir tendencias a partir de algunos indicadores de calidad de vida en el conjunto de países de dependencia mineral. A partir de gráficos Box-Plot e índices de correlación, se procedió a la descripción de tendencias estadísticas para realizar precisiones en torno a la calidad de vida -analizada a través del índice de desarrollo humano [ÍDH] y componentes- y variables económicas [exportaciones minerales como porcentaje del total de exportaciones y del producto interno bruto] y demográficas [fecundidad, mortalidad infantil]. Aunque no se precisó alguna correlación estadística entre el porcentaje de exportaciones minerales como parte del PIB con el ÍDH o alguno de sus componentes, se encontró relación significativa con el porcentaje como parte del total de exportaciones aunque -en su relación con el IDH y con el índice de logro educativo- sólo había relaciones inversas de carácter leve. En relación con las variables demográficas, sólo se encontró relaciones leves entre el porcentaje de exportaciones minerales sobre exportaciones totales con la tasa de fecundidad total y la tasa de mortalidad infantil, sin que se haya encontrado alguna significatividad en la tasa de mortalidad de niños menores de 5 años. Se precisó que, aunque la mayor parte de los países con dependencia mineral poseen valores ÍDH medio, los valores reflejan fuertes diferencias regionales, distribuciones asimétricas positivas matizadas en lo referente a las exportaciones minerales y dispersión desigual de los valores ÍDH, siendo mayor entre los países de alta dependencia mineral.

In order to achieve this aim, the idea that allocating money to dependency is a expenditure must be banished and consider it as an investment that contributes to economic development and can be quantified in terms of impact on employment generation and wealth. This study analyses the economic impact of the dependency care (given through residential care centres or day care centres in the region of Cantabria (Spain, as well as of the Home Care System. Dependency care generates directly 24 jobs for every million EUR invested by the Administration in this sector. If we include the indirect and induced impact, the job creation rises to 36 jobs, with the consequent effect in production, consumption and tax revenues.El envejecimiento de la población en la mayoría de los países desarrollados marca la necesidad de establecer políticas de actuación que garanticen la atención a dicha población. Para ello, se debe desterrar la idea de que los recursos destinados a la dependencia son un gasto, considerarlos como una inversión que contribuye al desarrollo económico y que puede cuantificarse en términos de impacto en la generación de empleo y riqueza. Este estudio analiza el impacto económico del conjunto de centros de atención a la dependencia (tanto residenciales como de atención diurna en la región de Cantabria (España, así como del Servicio de Ayuda a Domicilio. De manera directa, la atención a la dependencia genera 24 empleos por cada millón de euros invertido por la Administración en el sector. Si incluimos el impacto indirecto e inducido, esta generación de empleo se eleva a 36, con el consiguiente efecto sobre la producción, el consumo y la recaudación de impuestos.

    The present work introduces an improved SPICE equivalent electrical model of silicon photomultiplier (SiPM) detectors, in order to simulate and predict their transient response to avalanche triggering events. In particular, the developed circuit model provides a careful investigation of the magnitude and timing of the read-out signals and can therefore be exploited to perform reliable circuit-level simulations. The adopted modeling approach is strictly related to the physics of each basic microcell constituting the SiPM device, and allows the avalanche timing as well as the photodiode current and voltage to be accurately simulated. Predictive capabilities of the proposed model are demonstrated by means of experimental measurements on a real SiPM detector. Simulated and measured pulses are found to be in good agreement with the expected results. -- Highlights: • An improved SPICE electrical model of silicon photomultipliers is proposed. • The developed model provides a truthful representation of the physics of the device. • An accurate charge collection as a function of the overvoltage is achieved. • The adopted electrical model allows reliable circuit-level simulations to be performed. • Predictive capabilities of the adopted model are experimentally demonstrated.

  7. Modeling the Nab Experiment Electronics in SPICE

    Blose, Alexander; Crawford, Christopher; Sprow, Aaron; Nab Collaboration

    2017-09-01

    The goal of the Nab experiment is to measure the neutron decay coefficients a, the electron-neutrino correlation, as well as b, the Fierz interference term to precisely test the Standard Model, as well as probe for Beyond the Standard Model physics. In this experiment, protons from the beta decay of the neutron are guided through a magnetic field into a Silicon detector. Event reconstruction will be achieved via time-of-flight measurement for the proton and direct measurement of the coincident electron energy in highly segmented silicon detectors, so the amplification circuitry needs to preserve fast timing, provide good amplitude resolution, and be packaged in a high-density format. We have designed a SPICE simulation to model the full electronics chain for the Nab experiment in order to understand the contributions of each stage and optimize them for performance. Additionally, analytic solutions to each of the components have been determined where available. We will present a comparison of the output from the SPICE model, analytic solution, and empirically determined data.

    Garlic and salt spice is widely used in Brazilian cookery, but it has a high sodium content; as high sodium intake has been strongly correlated to the incidence of chronic diseases. This study aimed to develop a garlic and salt spice with reduced sodium intake. Sensory evaluation was conducted by applying the spices to cooked rice. First, the optimal concentration of spice added during rice preparation was determined. Subsequently, seasonings (3:1) were prepared containing 0%, 50% and 25% less NaCl using a mixture of salts consisting of KCl and monosodium glutamate; a seasoning with a 0% NaCl reduction was established as a control. Three formulations of rice with different spices were assessed according to sensory testing acceptance, time-intensity and temporal domain of sensations. The proportions of salts used in the garlic and salt spice did not generate a strange or bad taste in the products; instead, the mixtures were less salty. However, the seasonings with lower sodium levels (F2 and F3) were better accepted in comparison to the traditional seasoning (F1). Therefore, a mixture of NaCl, KCl and monosodium glutamate is a viable alternative to develop a garlic and salt spice with reduced sodium intake.

It has been experimentally demonstrated that spices, herbs, and their extracts possess antimicrobial, anti-inflammatory, antirheumatic, lipid-lowering, hepatoprotective, nephroprotective, antimutagenic and anticancer activities, besides their gastroprotective and anti-ulcer activities. Despite a number of reports on the toxicity of herbs and spices, they are generally accepted as safer alternatives to conventional therapy against gastric ulcers. To this end, it is also believed, that excessive consumption of spices may favor the pathogenesis of gastric and duodenal ulcer and some studies have substantiated this common perception. Based on various in vivo experiments and clinical studies, on the effects of spices and herbs on gastric ulcers, it has indeed been shown that certain spices do possess remarkable anti-ulcer properties mediated by antisecretory, cytoprotective, antioxidant, and anti-Helicobacter pylori effects and mechanisms regulated by nitric oxide, prostaglandins, non-protein sulfhydryl molecules and epidermal growth factor expression. Accordingly, their consumption may attenuate and help prevent peptic ulcer disease. In the present review, the beneficial effects of spices and herbal nutritive components on the gastric mucosa are discussed against the paradigm of their deleterious potential.

    The objective of this study was to investigate prebiotic potential, chemical composition, and antioxidant capacity of spice extracts. Seven culinary spices including black pepper, cayenne pepper, cinnamon, ginger, Mediterranean oregano, rosemary, and turmeric were extracted with boiling water. Major chemical constituents were characterized by RP-HPLC-DAD method and antioxidant capacity was determined by measuring colorimetrically the extent to scavenge ABTS radical cations. Effects of spice extracts on the viability of 88 anaerobic and facultative isolates from intestinal microbiota were determined by using Brucella agar plates containing serial dilutions of extracts. A total of 14 phenolic compounds, a piperine, cinnamic acid, and cinnamaldehyde were identified and quantitated. Spice extracts exhibited high antioxidant capacity that correlated with the total amount of major chemicals. All spice extracts, with the exception of turmeric, enhanced the growth of Bifidobacterium spp. and Lactobacillus spp. All spices exhibited inhibitory activity against selected Ruminococcus species. Cinnamon, oregano, and rosemary were active against selected Fusobacterium strains and cinnamon, rosemary, and turmeric were active against selected Clostridium spp. Some spices displayed prebiotic-like activity by promoting the growth of beneficial bacteria and suppressing the growth of pathogenic bacteria, suggesting their potential role in the regulation of intestinal microbiota and the enhancement of gastrointestinal health. The identification and quantification of spice-specific phytochemicals provided insight into the potential influence of these chemicals on the gut microbial communities and activities. Future research on the connections between spice-induced changes in gut microbiota and host metabolism and disease preventive effect in animal models and humans is needed. © 2017 The Authors.

    Alam, Mohammad Khorshed.

    2007-01-01

    A study was carried out to detect the chemical change that might occur in irradiated orange and spice. Oxidative DNA damage can induce the production of 8-hydroxydeoxyguanine (8-OHdG) and thus the level of 8-hydroxydeoxyguanine was investigated using enzyme linked immunosorbent assay (ELISA) in the irradiated orange and spice which was compared with the unirradiated samples. By the difference in the oxidized guanine level that produce 8-hydroxydeoxyguanine in the irradiated and unirradiated samples, it can be clearly understood that detection of irradiated orange and spice is possible using monoclonal antibody for 8-hydroxydeoxyguanine in the ELAISA assay.(author)

    Spices have been used since ancient times. Although they have been employed mainly as flavoring and coloring agents, their role in food safety and preservation have also been studied in vitro and in vivo. Spices have exhibited numerous health benefits in preventing and treating a wide variety of diseases such as cancer, aging, metabolic, neurological, cardiovascular, and inflammatory diseases. The present review aims to provide a comprehensive summary of the most relevant and recent findings on spices and their active compounds in terms of targets and mode of action; in particular, their potential use in food preservation and enhancement of shelf life as a natural bioingredient.

    Some spices produced in Argentina ground red pepper, anise, fennel, laurel, paprika, Cayenne pepper, cumin (seed), and mayoram (leaves and flowers), were irradiated to inactivate microbial lead, without causing significant chemical or sensory alterations. They were packed in polyethylene bags of 100 m thickness, and irradiated at the 60 Co semi-industrial facility of the Ezeiza Atomic Center, with doses of 7 and 10 kGy, and dose rate of 93.87 Gy/min. Dosimetric data were evaluated with potassium nitrate. Control and irradiated samples were stored at room temperature. Chemical analysis were performed to verify the Argentine Alimentary Codex specifications: water content; essence; total ash; ash insoluble in acid; alcoholic, volatile ether and non-volatile ether extracts; starch; and crude fiber. Besides, colour and volatile substances were analyzed. No differences were found between control and irradiated samples, with the exception of an increase in the total amount of volatiles released by irradiated spices, and a slight colour loss in mayoram. Microbiological determinations consisted of aerobic plate count, yeasts and moulds, coliform bacteria, Salmonella, Staphylococcus aureus, mesophilic and thermophilic sporeformers, enterococci and Clostridium perfringens. Microbial load in control samples oscillated between 10 3 and 10 6 microorganisms per gram, and was inhibited with 10 kGy to undetectable level. With 7 kGy, survivors were still detected in: cumin, anise, laurel, red pepper, fennel and paprika. So, the purpose of this work was accomplished with the dose of 10 kGy. Great improvement on the quality of those products which being stored at room temperature are consumed in the raw state, would be attained. (Author) [es

    Padwal-Desai, S.R.; Sharma, Arun; Amonkar, S.V.

    1987-01-01

    Number of insect species were identified in chilli (Capsicum annum Linn), turmeric (Curcuma longa Linn), ginger (Zingiber officinale Roscoe), pepper (Piper nigrum Linn) and coriander (Coriandrum sativum) and also in two commercial brands of prepacked ground spices. Lasioderma serricorne (Cigarette beetle), Oryzaephilus surinamensis (Saw toothed grain beetle), Rhizopertha dominica (Lesser grain borer), Sitotroga cerealella (Angoumois grain moth) and Tribolium castaneum (Red flour beetle) were the predominant pest species found in these spices. Exposure of spices to Co 60 gamma irradiation at 1 kGy dose level did not show adult emergence of insects in these species during storage at ambient temperature (28-30degC) indicating that the radiation dose (10 kGy) that has been shown to be effective for microbial decontamination of spices destroys insect pests as well.

    The microbiological quality of 351 samples of nine types of spices including black pepper, caraway, cinnamon, cow parsnip, curry powder, garlic powder, red pepper, sumac, and turmeric, collected from retail shops in Tehran during 2007, was determined. The numbers of aerobic mesophilic bacteria, Escherichia coli, and molds exceeded Iran's National Standard limits, at 63.2% (>5 × 10(5) CFU/g), 23.4% (>0.3 MPN/g), and 21.9% (>5 × 10(3) CFU/g) of the studied samples, respectively. Coliform contamination was more than 10(3) MPN/g in 24.8% of samples. High contamination of retail spices is considered an indication of environmental or fecal contamination due to unhygienic practices in their production. Use of spices with high microbial content could increase the chance of food spoilage and transmission of foodborne pathogens. Accordingly, application of food safety measurements to reduce microbial counts in spices is strongly recommended.

    Kaneko, Nobutada; Ito, Hitoshi; Ishigaki, Isao

    1990-01-01

    To evaluate the radiation-induced deterioration of lipid in spices, peroxide value, iodine value and acid value were measured after extraction by chloroform. Peroxide values of black pepper and white pepper were not increased by gamma-irradiation with doses below 30 kGy and gradually increased at higher dose up to 80 kGy in this study. On contrary, peroxide values of clove and rosemary increased rather quickly below 20 kGy of gamma-irradiation, and they became stationary at higher dose. Iodine values and acid values had relationship with peroxide values on each kind of spices. On the storage study of irradiated spices, peroxide values decreased quickly during 20 days storage as same as nonirradiated spices, and it became stationary after 20 to 50 days storage at 30degC. Enhancement of oxidized deterioration were not observed even higher irradiation doses up to 80 kGy in this study. (author)

    Thermoluminescence (TL) analysis has been shown to be one of the most applicable methods for the detection of γ-irradiated spices. This analysis was introduced as a detection technique for irradiated spices using the whole sample. It was then found that the origin of the TL response to be mineral dust adhering to the spices. TL measurements on separated minerals and the normalised TL measurement by re-irradiation was then established. This paper details investigations on TL measurements carried out using clean powdered spices stored for one year after being irradiated with doses of 1, 5, 10 and 30 kGy in order to clarify their applicable dose range, the effect of storage and mineral content. The effect of the mineral separation was also studied. (author)

  10. Can irradiation of spices be detected by chemiluminescence

    Delincee, H

    1987-01-01

    Chemiluminescence (CL) has been reported as a reliable identification measure for radiation processed spices. Luminescence intensities, however, vary considerably from one spice to another. Even for one spice from various producers, different results have been obtained. One of the main drawbacks of CL is its poor reproducibility. Attempts to reduce the variability have so far been unsuccessful. Since the CL response is frequently a non-monotone function of dose, the applied radiation dose cannot be estimated unequivocally. Attempts to establish an internal standard were not successful. A further hindrance for dose estimation is the fading of luminescence with storage time. In the case of juniper berries 50-78% of the irradiated samples could be identified correctly, depending on selection criteria. With marjoram, however, only one out of five samples could be identified. Variations in the radiation conditions did not change CL. However, an increase in CL was also noted in some experiments with fumigated spices. The CL measurement as a single tool for identifying radiation processed spices seems at the moment not to fulfil the requirements of reliable detection. A combination of methods may eventually allow identification of irradiated spices.

  11. The Role of Herbs and Spices in Cancer Prevention

    Kaefer, Christine M.; Milner, John A.

    2009-01-01

    Historically herbs and spices have enjoyed a rich tradition of use for their flavor-enhancement characteristics and for their medicinal properties. The rising prevalence of chronic diseases world-wide and the corresponding rise in health care costs is propelling interest among researchers and the public for these food related items for multiple health benefits, including a reduction in cancer risk and modification of tumor behavior. A growing body of epidemiological and preclinical evidence points to culinary herbs and spices as minor dietary constituents with multiple anticancer characteristics. This review focuses on the anti-microbial, antioxidant, and anti-tumorigenic properties of herbs and spices, their ability to influence carcinogen bioactivation, and likely anticancer contributions. While culinary herbs and spices present intriguing possibilities for health promotion, more complete information is needed about the actual exposures to dietary components that are needed to bring about a response and the molecular target(s) for specific herbs and spices. Only after this information is obtained will it be possible to define appropriate intervention strategies to achieve maximum benefits from herbs and spices without eliciting ill-consequences.

  12. Total and soluble oxalate content of some Indian spices.

    Ghosh Das, Sumana; Savage, G P

    2012-06-01

    Spices, such as cinnamon, cloves, cardamom, garlic, ginger, cumin, coriander and turmeric are used all over the world as flavouring and colouring ingredients in Indian foods. Previous studies have shown that spices contain variable amounts of total oxalates but there are few reports of soluble oxalate contents. In this study, the total, soluble and insoluble oxalate contents of ten different spices commonly used in Indian cuisine were measured. Total oxalate content ranged from 194 (nutmeg) to 4,014 (green cardamom) mg/100 g DM, while the soluble oxalate contents ranged from 41 (nutmeg) to 3,977 (green cardamom) mg/100 g DM. Overall, the percentage of soluble oxalate content of the spices ranged from 4.7 to 99.1% of the total oxalate content which suggests that some spices present no risk to people liable to kidney stone formation, while other spices can supply significant amounts of soluble oxalates and therefore should be used in moderation.

    1995-01-01

    Thermoluminescence analysis was used in an interlaboratory study to detect irradiation treatment of spices, herbs, and spice-herb mixtures in the dose range used for the reduction of microbial counts. About 3 and 9 months after irradiation, 14 participating laboratories determined the thermoluminescence of mineral contaminants that had been isolated from coded samples. A total of 18 different products (6 spices, 6 herbs, and 6 spice-herb mixtures) were examined. The method gave correct identifications as irradiated or nonirradiated in 99.1% of 317 samples. Only 3 irradiated samples were not correctly identified. This result was achieved by integration of whole glow curves. By glow curve analysis, a temperature range could be determined in which differentiation between irradiated and nonirradiated samples was even better than on the basis of the total integral values

    Full Text Available En la historia argentina reciente, la emergencia de la restricción externa ha reflejado la incompatibilidad de sostener un proceso de crecimiento económico con elevación del poder adquisitivo de los salarios de los trabajadores sin experimentar problemas de desequilibrios en el sector externo. En este trabajo se intentará encuadrar estos límites en un marco de relaciones de dependencia que estructuran la economía mundial en países centrales, semiperiféricos y periféricos. Dado que las transformaciones del sistema mundial en los últimos cuarenta años han provocado una actualización y perfeccionamiento de los mecanismos por los cuales se transfiere el excedente desde las economías periféricas hacia las economías centrales, se elaborará un Índice Sintético de Transferencia de Excedente que permita caracterizar la salida de capitales en la Argentina en el período 1970-2013. Así, se intentará vincular la re-emergencia de la restricción externa con las características estructurales de la economía, de su articulación con la economía mundial y de la transferencia de excedente.

  1. Traditional Indian spices and their health significance.

    Krishnaswamy, Kamala

    2008-01-01

    India has been recognized all over the world for spices and medicinal plants. Both exhibit a wide range of physiological and pharmacological properties. Current biomedical efforts are focused on their scientific merits, to provide science-based evidence for the traditional uses and to develop either functional foods or nutraceuticals. The Indian traditional medical systems use turmeric for wound healing, rheumatic disorders, gastrointestinal symptoms, deworming, rhinitis and as a cosmetic. Studies in India have explored its anti-inflammatory, cholekinetic and anti-oxidant potentials with the recent investigations focusing on its preventive effect on precarcinogenic, anti-inflammatory and anti atherosclerotic effects in biological systems both under in vitro and in vivo conditions in animals and humans. Both turmeric and curcumin were found to increase detoxifying enzymes, prevent DNA damage, improve DNA repair, decrease mutations and tumour formation and exhibit antioxidative potential in animals. Limited clinical studies suggest that turmeric can significantly impact excretion of mutagens in urine in smokers and regress precancerous palatal lesions. It reduces DNA adducts and micronuclei in oral epithelial cells. It prevents formation of nitroso compounds both in vivo and in vitro. It delays induced cataract in diabetes and reduces hyperlipidemia in obese rats. Recently several molecular targets have been identified for therapeutic / preventive effects of turmeric. Fenugreek seeds, a rich source of soluble fiber used in Indian cuisine reduces blood glucose and lipids and can be used as a food adjuvant in diabetes. Similarly garlic, onions, and ginger have been found to modulate favourably the process of carcinogenesis.

    Full Text Available Curcuma longa (Turmeric, belonging to Zingiberaceae family is one of the most useful herbal medicinal plants. Extensive researches have proven that most of the turmeric activities of the turmeric are due to curcumin. It has various useful properties with antioxidant activities and is useful in conditions such as inflammation, ulcer and cancer. It also has antifungal, antimicrobial renal and hepatoprotective activities. Therefore, it has the potential against various cancer, diabetes, allergies, arthritis, Alzheimer’s disease and other chronic and hard curable diseases. The purpose of this review was to provide a brief summary of the new and current knowledge of the effects of curcumin. The recently published papers in international cites such as PubMed/Medline, Science Citation Index and Google Scholar about turmeric were searched. Recent studies have authenticated the use of turmeric for various diseases especially oxidative stress induced ones such as cancer, diabetes mellitus and inflammatory disorders. It also is used as hepatoprotective, nephroprotective, anticoagulant and anti-HIV to combat AIDS. Curcumin, as a spice, exhibits great promise as a therapeutic agent. It has very low toxicity, too. As the global scenario is now changing towards the use of non-toxic plant products having traditional medicinal use, development of modern drugs from turmeric should be emphasized for the control of various diseases. Further evaluation needs to be carried out on turmeric in order to explore the concealed areas and their practical clinical applications, which can be used for the welfare of mankind.

    Prakash, Usha N S; Srinivasan, Krishnapura

    2012-02-01

    A few common spices are known to stimulate secretion of bile with higher amount of bile acids which play a major role in digestion and absorption of dietary lipids. It would be appropriate to verify if these spices enable efficient digestion and absorption during high-fat intake. In this context, dietary ginger (0.05%), piperine (0.02%), capsaicin (0.015%), and curcumin (0.5%) were examined for their influence on bile secretion, digestive enzymes of pancreas and absorption of dietary fat in high-fat (30%) fed Wistar rats for 8 weeks. These spices enhanced the activity of pancreatic lipase, amylase, trypsin and chymotrypsin by 22-57%, 32-51%, 63-81% and 12-38%, respectively. Dietary intake of spices along with high-fat enhanced fat absorption. These dietary spices increased bile secretion with higher bile acid content. Stimulation of lipid mobilisation from adipose tissue was suggested by the decrease in perirenal adipose tissue weight by dietary capsaicin and piperine. This was also accompanied by prevention of the accumulation of triglyceride in liver and serum in high-fat fed rats. Activities of key lipogenic enzymes in liver were reduced which was accompanied by an increased activity of hormone-sensitive lipase. Thus, dietary ginger and other spice compounds enhance fat digestion and absorption in high-fat fed situation through enhanced secretion of bile salts and a stimulation of the activity pancreatic lipase. At the same time, the energy expenditure is facilitated by these spices to prevent the accumulation of absorbed fat. Copyright © 2011 Society of Chemical Industry.

    Goto, Michiko; Yamazaki, Masao; Sekiguchi, Masayuki; Todoriki, Setsuko; Miyahara, Makoto

    2007-01-01

    Five blended spice sample were prepared by mixing irradiated and un-irradiated black pepper and paprika at different ratios. Blended black pepper containing 2%(w/w) of 5.4 kGy-irradiated black pepper showed no maximum at glow1. Irradiated black pepper samples, mixed to 5 or 10%(w/w), were identified as 'irradiated' or 'partially irradiated' or 'un-irradiated'. All samples with un-irradiated pepper up to 20%(w/w) were identified as irradiated'. In the case 5.0 kGy-irradiated paprika were mixed with un-irradiated paprika up to 5%(w/w), all samples were identified as irradiated'. The glow1 curves of samples, including irradiated paprika at 0.2%(w/w) or higher, exhibited a maximum between 150 and 250degC. The results suggest the existence of different critical mixing ratio for the detection of irradiation among each spices. Temperature range for integration of the TL glow intensity were compared between 70-400degC and approximate 150-250degC, and revealed that the latter temperature range was determined based on the measurement of TLD100. Although TL glow ratio in 150-250degC was lower than that of 70-400degC range, identification of irradiation was not affected. Treatment of un-irradiated black pepper and paprika with ultraviolet rays had no effect on the detection of irradiation. (author)

  6. A simple method for identification of irradiated spices

    Behere, A.; Desai, S.R.P.; Nair, P.M.; Rao, S.M.D.

    1992-01-01

    Thermoluminescence (TL) properties of curry powder, a salt containing spice mixture, and three different ground spices, viz, chilli, turmeric and pepper, were compared with TL of table salt. The spices other than curry powder, did not exhibit characteristic TL in the absence of salt. Therefore studies were initiated to develop a simple and reliable method using common salt for distinguishing irradiated spices (10 kGy) from unirradiated ones under normal conditions of storage. Common salt exhibited a characteristic TL glow at 170 o C. However, when present in curry powder, the TL glow of salt showed a shift to 208 o C. It was further observed that upon storage up to 6 months, the TL of irradiated curry powder retained about 10% of the original intensity and still could be distinguished from the untreated samples. From our results it is evident that common salt could be used as an indicator either internally or externally in small sachets for incorporating into prepacked spices. (author)

    Chaturvedi, T P

    2014-01-01

    Moist environment in the mouth varies and causes variable amounts of corrosion of dental materials. This is of concern particularly when metallic implants, metallic fillings, orthodontic appliances are placed in the hostile electrolytic environment in the human mouth. Components of diet rich in salt and spices are important factors influencing the corrosion of metallic appliances placed in the oral cavity. To study in vitro corrosion of orthodontic metallic brackets immersed in solutions of salt and spices in artificial saliva. Orthodontic brackets were used for corrosion studies in artificial saliva, salt, and spices using electrochemical technique and surface analysis. Electrochemical studies using different parameters were done in solutions of artificial saliva containing salt and spices. Photomicrographs from the optical microscope were also obtained. RESULTS of corrosion studies have clearly demonstrated that certain spices such as turmeric and coriander are effective in reducing corrosion, whereas salt and red chili have been found to enhance it. Surface analysis of small pits present on the surface of the as-received bracket will initiate corrosion which leads to more pitting.

  10. Development of a microbiological irradiation detection method for spices

    Koshikawa, T.; Takekawa, T.; Miyahara, M.

    2009-01-01

    In order to judge whether certain spices had been irradiated or not, we examined the possibility of developing a method based on the microbiological examination of spices. We used the total bacteria count in conjunction with the ratio of B. megaterium and B. cereus to the total bacteria count. The examination results of 6 kinds of spices with or without irradiation (black pepper, white pepper, coriander, paprika, ginger and turmeric), were as follows. Total bacteria counts over 10E5 CFU/g indicated that the samples were 'unirradiated'. When the total bacteria count was less than 10E5 CFU/g, and the ratio of B. megaterium and B. cereus to the total count was more than 30%, a history of irradiation of the samples was indicated. When ratios of B. megaterium and B. cereus were less than 30% and the total bacteria count was also less than 10E5 CFU/g, 'uncertainty' of irradiation was indicated. In this case, it would be possible to confirm whether spices were 'unirradiated' or 'irradiated' by using another detection method. This detection method was applicable to other spices except for paprika. The samples judged as 'irradiated' by using this detection method, surely proved to have a history of irradiation treatment

    2016-02-01

    Spices and dried vegetable seasonings are potential sources of bacterial contamination for foods. However, little is known about lactic acid bacteria (LAB) in spices and dried vegetables, even though certain LAB may cause food spoilage. In this study, we enumerated LAB in 104 spices and dried vegetables products aimed for the food manufacturing industry. The products were obtained from a spice wholesaler operating in Finland, and were sampled during a one-year period. We picked isolates (n = 343) for species identification based on numerical analysis of their ribotyping patterns and comparing them with the corresponding patterns of LAB type strains. We found LAB at levels >2 log CFU/g in 68 (65%) of the samples, with the highest counts detected from dried onion products and garlic powder with counts ranging from 4.24 to 6.64 log CFU/g. The LAB identified were predominantly Weissella spp. (61%) and Pediococcus spp. (15%) with Weissella confusa, Weissella cibaria, Weissella paramesenteroides, Pediococcus acidilactici and Pediococcus pentosaceus being the species identified. Other species identified belonged to the genera of Enterococcus spp. (8%), Leuconostoc spp. (6%) and Lactobacillus spp. (2%). Among the LAB identified, Leuconostoc citreum, Leuconostoc mesenteroides and W. confusa have been associated with food spoilage. Our findings suggest that spices and dried vegetables are potential sources of LAB contamination in the food industry. Copyright © 2015 Elsevier Ltd. All rights reserved.

  13. Determination of fluoride in spices using microwave induced oxygen combustion

    Emanuel Šucman

    2012-01-01

    Full Text Available Fluorine is essential in human and/or animal nutrition; therefore, so it is important to know its concentration in a diet. One of the possible sources of fluorine for humans is spice, containing various amounts of this trace element. This work describes the method for fluoride determination in various kinds ofspices using microwave-supported sample preparation in high pressure oxygen atmosphere followed by potentiometry with a fluoride ion-selective electrode. Parameters of the microwave device for combustion procedure were checked and optimized in order to find settings ensuring complete sample combustion and/or absorption of the analyte in the absorption solution. For the ion-selective electrode measurement, the technique of standard straight line was chosen. Concentrations of fluorides in spices and spice blends under investigation ranged from 3.15 mg·kg-1 to 26.08 mg·kg-1. In order to check the accuracy of the method Certified Reference Material Fluoride in Vegetation NIST 2695 was used and a good agreement between certified and found values was found. The precision expressed as the relative standard deviation ranged from 0.6% to 5.0%. The method is fast, accurate and reliable for this kind of analysis. In recent literature data on fluoride concentrations in spices and/or spice blends have not been found.

    Relecom, Ken; Larcheveque, Cyril; Constant, Joël; Autissier, Nordahl; Pornin, Arnaud; Martini, Nicolas

    2015-09-01

    The SPICE Door Mechanism (SDM) is foreseen to be flown on Solar Orbiter, to close the SPICE instrument aperture and shield it from the solar flux and from contamination. The environment it is exposed to is particularly extreme, as the Solar Orbiter mission will reach a distance of 0.28 AU (41’887’403.8 km) to the Sun, and the SPICE instrument will be looking directly at it. Because of its position at the far end of a cantilevered structure, the SDM is also exposed to amplified launch loads and must remain very light and compact. The cleanliness constraints are also very tight, as the mechanism is positioned directly at the aperture of the SPICE spectrometer.To tackle these issues, two novelties were introduced on the SPICE Door Mechanism:- A specifically engineered reflective coating toprotect the Aluminium door from the heat generatedby the solar flux- The use of miniature profile rail type linearbearings to support the door during launch andallow its motion during the missionThis paper details the design and verification approach applied for these two innovations and for the mechanism as a whole, as well as the results and findings from the testing carried out on the Bread Board, Qualification and Flight models.

    Przygodzka, Małgorzata; Zieliński, Henryk; Ciesarová, Zuzana; Kukurová, Kristina; Lamparski, Grzegorz

    2016-07-01

    The aim of this study was to find out the effect of selected spices on chemical and sensorial markers in cakes formulated on rye and light buckwheat flour fortified with spices. Among collection of spices, rye-buckwheat cakes fortified individually with cloves, nutmeg, allspice, cinnamon, vanilla, and spice mix revealed the highest sensory characteristics and overall quality. Cakes fortified with cloves, allspice, and spice mix showed the highest antioxidant capacity, total phenolics, rutin, and almost threefold higher available lysine contents. The reduced furosine content as well as free and total fluorescent intermediatory compounds were observed as compared to nonfortified cakes. The FAST index was significantly lowered in all cakes enriched with spices, especially with cloves, allspice, and mix. In contrast, browning index increased in compare to cakes without spices. It can be suggested that clove, allspice, vanilla, and spice mix should be used for production of safety and good quality cakes.

  19. Small Particles Intact Capture Experiment (SPICE)

    Nishioka, Ken-Ji; Carle, G. C.; Bunch, T. E.; Mendez, David J.; Ryder, J. T.

    1994-01-01

    The Small Particles Intact Capture Experiment (SPICE) will develop technologies and engineering techniques necessary to capture nearly intact, uncontaminated cosmic and interplanetary dust particles (IDP's). Successful capture of such particles will benefit the exobiology and planetary science communities by providing particulate samples that may have survived unaltered since the formation of the solar system. Characterization of these particles may contribute fundamental data to our knowledge of how these particles could have formed into our planet Earth and, perhaps, contributed to the beginnings of life. The term 'uncontaminated' means that captured cosmic and IDP particles are free of organic contamination from the capture process and the term 'nearly intact capture' means that their chemical and elemental components are not materially altered during capture. The key to capturing cosmic and IDP particles that are organic-contamination free and nearly intact is the capture medium. Initial screening of capture media included organic foams, multiple thin foil layers, and aerogel (a silica gel); but, with the exception of aerogel, the requirements of no contamination or nearly intact capture were not met. To ensure no contamination of particles in the capture process, high-purity aerogel was chosen. High-purity aerogel results in high clarity (visual clearness), a useful quality in detection and recovery of embedded captured particles from the aerogel. P. Tsou at the Jet Propulsion Laboratory (JPL) originally described the use of aerogel for this purpose and reported laboratory test results. He has flown aerogel as a 'GAS-can Lid' payload on STS-47 and is evaluating the results. The Timeband Capture Cell Experiment (TICCE), a Eureca 1 experiment, is also flying aerogel and is scheduled for recovery in late April.

  20. Identification of irradiated spices with aid of scintillation counter

    Uusheimo, K.

    1989-08-01

    The aim off the work was to determine how one can identify gamma-irradiated spices with aid of a scintillation counter (LKB/Wallac 1219 RackBeta Spectral) by chemiluminescence measurements. Even though scintillation counters are more sensitive than real luminometers they have not been capable in identifying the irradiated spices after contact with photosensitizer like luminol, isoluminol and lucigenin presumably because the actual chemiluminescence reaction took place before the sample vial reached the measuring range. Whereas it was noticed that the identification of pure, dry allspice, black pepper, white peppar and cardemom was possible without any solutions when there were also present similar unirradiated spices. The identification was possible even after 23 weeks duration depending on the dose of the irradiation (10 kGy or 50 kGy) and the weight of the samples (1 g or 9 g). The duration of the investigation was 23 weeks

  1. The industrial potential of herbs and spices - a mini review.

    Leja, Katarzyna B; Czaczyk, Katarzyna

    2016-01-01

    Herbs and spices have been used for food and medicinal purposes for centuries - the first recorded evidence of their use dates back to 1500BC and the Ebers Papyrus, which mentioned spices such as anise, mustard, saffron, cinnamon, and cassia. Now, in the 21st century, a variety of secondary compounds produced by plants are used in many fields of industry, such as food production (to improve taste, to provide vitamins and macro- and microelements, and also to inhibit food spoilage caused by foodborne bacteria), in medicine (in the treatment of various diseases; in chemoprevention and cancer therapy; as a source of natural antimicrobials for the treatment of infectious disease), and in pharmacology and cosmetology (in dietary supplements, and as a result of the demand for preservative-free cosmetics, to reduce the risk of methylparaben allergies). The aim of this review is to present the major active compounds in herbs and spices and explore their potential applications in industry.

  2. Cytotoxicity of extracts of spices to cultured cells.

    Unnikrishnan, M C; Kuttan, R

    1988-01-01

    The cytotoxicity of the extracts from eight different spices used in the Indian diet was determined using Dalton's lymphoma ascites tumor cells and human lymphocytes in vitro and Chinese Hamster Ovary cells and Vero cells in tissue culture. Alcoholic extracts of the spices were found to be more cytotoxic to these cells than their aqueous extracts. Alcoholic extracts of several spices inhibited cell growth at concentrations of 0.2-1 mg/ml in vitro and 0.12-0.3 mg/ml in tissue culture. Ginger, pippali (native to India; also called dried catkins), pepper, and garlic showed the highest activity followed by asafetida, mustard, and horse-gram (native to India). These extracts also inhibited the thymidine uptake into DNA.

  3. Multitargeting by turmeric, the golden spice: From kitchen to clinic.

    Gupta, Subash C; Sung, Bokyung; Kim, Ji Hye; Prasad, Sahdeo; Li, Shiyou; Aggarwal, Bharat B

    2013-09-01

    Although much has been published about curcumin, which is obtained from turmeric, comparatively little is known about turmeric itself. Turmeric, a golden spice obtained from the rhizome of the plant Curcuma longa, has been used to give color and taste to food preparations since ancient times. Traditionally, this spice has been used in Ayurveda and folk medicine for the treatment of such ailments as gynecological problems, gastric problems, hepatic disorders, infectious diseases, and blood disorders. Modern science has provided the scientific basis for the use of turmeric against such disorders. Various chemical constituents have been isolated from this spice, including polyphenols, sesquiterpenes, diterpenes, triterpenoids, sterols, and alkaloids. Curcumin, which constitutes 2-5% of turmeric, is perhaps the most-studied component. Although some of the activities of turmeric can be mimicked by curcumin, other activities are curcumin-independent. Cell-based studies have demonstrated the potential of turmeric as an antimicrobial, insecticidal, larvicidal, antimutagenic, radioprotector, and anticancer agent. Numerous animal studies have shown the potential of this spice against proinflammatory diseases, cancer, neurodegenerative diseases, depression, diabetes, obesity, and atherosclerosis. At the molecular level, this spice has been shown to modulate numerous cell-signaling pathways. In clinical trials, turmeric has shown efficacy against numerous human ailments including lupus nephritis, cancer, diabetes, irritable bowel syndrome, acne, and fibrosis. Thus, a spice originally common in the kitchen is now exhibiting activities in the clinic. In this review, we discuss the chemical constituents of turmeric, its biological activities, its molecular targets, and its potential in the clinic. © 2012 WILEY-VCH Verlag GmbH & Co.

  4. Low-angle X-ray scattering from spices

    Desouky, O.S.; Ashour, Ahmed H.; Abdullah, Mohamed I.; Elshemey, Wael M.

    2002-01-01

    Low-angle scattering of X-rays is characterized by the presence of one or more peaks in the forward direction of scattering. These peaks are due to the interference of photons coherently scattered from the molecules of the medium. Thus these patterns are closely linked to the molecular structure of the investigated medium. In this work, low-angle X-ray scattering (LAXS) profiles of five spices; pimpinella anisum (anise), coriandrum sativum (coriander), cuminum cyminum (cumin), foenculum vulgare (fennel) and nigella sativa (nigella or black cumin) are presented after extensive measurements. It is found that all spices exhibit one characteristic peak at a scattering angle around 10 deg. This is equivalent to a value x=0.0565 A -1 , where x=sin(θ/2)/λ. The full width at half maximum (FWHM) of this peak is found to be characteristic for each type of the investigated spices. The possibility to detect the irradiation of these spices from their LAXS profiles is also examined after 10, 20, 30 and 40 kGy doses of gamma radiation. Except for anise, coriander and cumin at 40 kGy, there are no detectable deviations from the control samples in the scattering profiles of irradiated samples. These results comply with the recommendations of the FDA (US Food and Drug Administration) which defines 30 kGy as the maximum dose for irradiation of spices. The present technique could be used to detect over-irradiation, which causes damage to the molecular structure of some spices

  5. Effect of Spices Mixture and Gamma Irradiation on Sausage Quality

    2015-01-01

    This investigation was carried out to study the effect of spices mixture on reducing the oxidation of fat and to improve the quality and organoleptic characteristics as well as extension of shelf-life of beef sausage. Beef sausages were mixed with three different levels (0.5%, 1.5% and 2.5%) of spices mixture (cardamom, clove, cubeb, laurel leaves, cinnamon, black pepper, rosemary, parpicu, fennel and coriander). The sausages were packed in polyethylene bags and irradiated at 2.5, 5 and 7.5 kGy then stored at 5±1°C for 48 days. Microbiological, biochemical and physical analyses as well as organoleptic evaluation were carried out. Results indicated that increasing the spices level decreased the total bacterial count (TBC), molds, yeasts and psychrophilic bacteria (PB) while total volatile nitrogen (TVN), thiobarbituric acid (TBA), peroxide value (PV) and acid value (AV) were increased in treated samples (1.5% and 2.5%) as compared to control (0.5%). On the other hand, the spices decreased TVN, TBA, PV and AV in treated sausages during cold storage while the physical parameters were increased and the best qualities of cold irradiated sausages were observed at the level 2.5% then 1.5% of spices, and the cooking yield and cooking loss and the organoleptic scores (based on over all acceptability) were better than the control sample (0.5%). The results of spices mixture showed that the level 2.5% can reduce oxidation of fat and improve quality and organoleptic characteristics as well as extension of shelf-life of cold irradiated beef sausage stored for 48 days.

    2011-01-01

    Along with a series of research works on the physical prototype and properties of the memory cell, an SPICE model for phase-change memory (PCM) simulations based on Verilog-A language is presented. By handling it with the heat distribution algorithm, threshold switching theory and the crystallization kinetic model, the proposed SPICE model can effectively reproduce the physical behaviors of the phase-change memory cell. In particular, it can emulate the cell's temperature curve and crystallinity profile during the programming process, which can enable us to clearly understand the PCM's working principle and program process.

    Alam, M. K.; Choudhury, N.; Chowdhury, N. A.; Youssouf, Q.M.

    1994-01-01

    Spices such as coriander, cumin, turmeric, chilli collected from local market were found to be highly contaminated with bacteria and fungi. A dose of 3 kGy without heat treatment reduced the microbial load from 6 log to 3 log and from 5 log to 2 log units depending on the storage temperature whereas the same dose of radiation combined with heat treatment reduced the microbial load from 6 log to 2 log units and from 4 log to below detectable level depending on storage condition. The combination treated spices retained good organoleptic quality in comparison to that of only irradiated species with higher dose. 11 refs., 2 tables (author)

    Along with a series of research works on the physical prototype and properties of the memory cell, an SPICE model for phase-change memory (PCM) simulations based on Verilog-A language is presented. By handling it with the heat distribution algorithm, threshold switching theory and the crystallization kinetic model, the proposed SPICE model can effectively reproduce the physical behaviors of the phase-change memory cell. In particular, it can emulate the cell's temperature curve and crystallinity profile during the programming process, which can enable us to clearly understand the PCM's working principle and program process.

  16. Modeling high-power RF accelerator cavities with SPICE

    Humphries, S. Jr.

    1992-01-01

    The dynamical interactions between RF accelerator cavities and high-power beams can be treated on personal computers using a lumped circuit element model and the SPICE circuit analysis code. Applications include studies of wake potentials, two-beam accelerators, microwave sources, and transverse mode damping. This report describes the construction of analogs for TM mn0 modes and the creation of SPICE input for cylindrical cavities. The models were used to study continuous generation of kA electron beam pulses from a vacuum cavity driven by a high-power RF source

  17. Reduction of the number of germs in spices by radappertization

    Beczner, Laszlone; Kiss, Istvan

    1983-01-01

    The sterilization by fumigation with ethylene oxide and propylene oxide of ground paprika and spice mixtures used in preserves and meat industry was compared with the radappertization of the same spices. The number of germs including that of spores and moulds was determined. It can be established that irradiation with ionizing radiation (5 kGy) has the same effect on the reduction of the number of germs as sterilization by ethylene oxide. In addition, the side effects of sterilization can be avoided. (V.N.)

  18. Application of 'SPICE' to predict temperature distribution in heat pipes

    Li, H M; Liu, Y; Damodaran, M [Nanyang Technological Univ., Singapore (SG). School of Mechanical and Production Engineering

    1991-11-01

    This article presents a new alternative approach to predict temperature distribution in heat pipes. In this method, temperature distribution in a heat pipe, modelled as an analogous electrical circuit, is predicted by applying SPICE, a general-purpose circuit simulation program. SPICE is used to simulate electrical circuit designs before the prototype is assembled. Useful predictions are obtained for heat pipes with and without adiabatic sections and for heat pipes with various evaporator and condenser lengths. Comparison of the predicted results with experiments demonstrates fairly good agreement. It is also shown how interdisciplinary developments could be used appropriately. (author).

    1989-01-01

    Blind tests were performed measuring the thermoluminescence intensity on samples from 10 different spices that were either irradiated or unirradiated. The chemiluminescence was measured on 10 additional spice samples. Twelve institutions participated in this collaborative study. Thresholds were defined which, when exceeded, declare samples as irradiated. The recovering rate was nearly 100% for samples investigated by thermoluminescence. Only one out of 495 irradiated samples was not identified. By using chemiluminescence, the participants succeeded in identifying 99% of unirradiated samples and 75% of irradiated samples from a total of 490 samples. (author).

  20. Modelización financiero-actuarial de un seguro de dependencia = Long Term Care Insurance Actuarial Model

    Herranz Peinado, Patricia

    2008-01-01

    Full Text Available España ha seguido la tendencia de otros países en cuanto a la cobertura de las personas dependientes, es decir, aquellas que necesitan ayuda para realizar las tareas básicas de la vida diaria, y lo ha hecho mediante la aprobación de la Ley de Promoción de la Autonomía Personal y Atención a las personas en situación de Dependencia, que se basa en la financiación pública. A pesar de los esfuerzos para el desarrollo de la Ley, ésta no está dando los frutos que debiera haber dado y se hace necesaria la existencia de productos privados de cobertura que puedan atender a las necesidades de aquellos que los demandan. Dado los escasos estudios que sobre este tema existen todavía en nuestro país, el establecer una aproximación a las primas de un seguro privado de dependencia puede servir de referencia para el análisis de su comercialización por parte de las aseguradoras. En este trabajo se trata de analizar una serie de cuestiones que den respuesta a dos objetivos. Por una parte, establecer un modelo financiero-actuarial que sirva como apoyo en el diseño de productos privados que cubran la dependencia y, por otra, realizar una aproximación a las bases técnicas actuariales que lleven a la cuantificación de las primas. = Spain has followed the trend of other countries about long term care, that is, people who need help to perform the basic tasks of daily living. In December 2006, Spanish Parliament approved the law called Ley de Promoción de la Autonomía Personal y Atención a las personas en situación de Dependencia, with public financing. This law is not producing the expected results, and it makes necessary the existence of private insurance. Currently, there are few studies on long term care in our country. An approach to premiums of a private insurance can serve as reference for the studies by insurers. This work tries to study a series of questions responding simultaneously to two goals, establishing an actuarial model and, on

    A new SPICE model of irradiated MOSFET taking into account the real response of the 4 electrodes is proposed. The component that has been simulated is an NMOS transistor issued from the AMS BiCMOS 0.8 {mu}m technology. A comparison between SPICE-generated transients and PISCES device simulation demonstrates the accuracy benefits when used in complex electronic architectures. This model could be used when designing electronic circuits able to sustain hardening due to SEE (single event effect), it will be an efficient complement to the physical simulations.

  7. Contaminated Mexican steel incident

    1985-01-01

    This report documents the circumstances contributing to the inadvertent melting of cobalt 60 (Co-60) contaminated scrap metal in two Mexican steel foundries and the subsequent distribution of contaminated steel products into the United States. The report addresses mainly those actions taken by US Federal and state agencies to protect the US population from radiation risks associated with the incident. Mexico had much more serious radiation exposure and contamination problems to manage. The United States Government maintained a standing offer to provide technical and medical assistance to the Mexican Government. The report covers the tracing of the source to its origin, response actions to recover radioactive steel in the United States, and return of the contaminated materials to Mexico. The incident resulted in significant radiation exposures within Mexico, but no known significant exposure within the United States. Response to the incident required the combined efforts of the Nuclear Regulatory Commission (NRC), Department of Energy, Department of Transportation, Department of State, and US Customs Service (Department of Treasury) personnel at the Federal level and representatives of all 50 State Radiation Control Programs and, in some instances, local and county government personnel. The response also required a diplomatic interface with the Mexican Government and cooperation of numerous commercial establishments and members of the general public. The report describes the factual information associated with the event and may serve as information for subsequent recommendations and actions by the NRC. 8 figures

    2013-12-10

    To report and associate acute cerebral infarctions in 2 young, previously healthy siblings with use of the street drug known as "spice" (a synthetic marijuana product, also known as "K2"), which they independently smoked before experiencing acute embolic-appearing ischemic strokes. We present history, physical examination, laboratory data, cerebrovascular imaging, echocardiogram, ECG, and hospital course of these patients. We found that in both siblings spice was obtained from the same source. The drug was found to contain the schedule I synthetic cannabinoid JWH-018. Full stroke workup was unrevealing of a stroke etiology; urine drug screen was positive for marijuana. We found that our 2 patients who smoked the street drug spice had a temporal association with symptoms of acute cerebral infarction. This association may be confounded by contaminants in the product consumed (i.e., marijuana or an unidentified toxin) or by an unknown genetic mechanism. The imaging of both patients suggests an embolic etiology, which is consistent with reports of serious adverse cardiac events with spice use, including tachyarrhythmias and myocardial infarctions.

    The bacterial contamination was tested in 26 samples of spices. Chili, allspice and paprika were the most contaminated spices by bacteria. Five bacterial genera were isolated, namely bacillus, staphylococcus, streptococcus, micrococcus, and coccobacillus, all being gram-positive. Most isolates have been related to the genus bacillus. The bacterial isolates were identified as B. alvei, B. circulans, B. megaterium, B. pasteurii, B. pumilus, B. thuringiensis, B. sphaericus, B. incertaesedis, Micrococcus luteus, staphylococcus aureus, streptococcus sp. and coccobacillus sp. Irradiation of spices led to a significant decrease in the bacterial count of all samples. The dose required to inhibit completely the natural bacterial flora was 25 KGY. The most radioresistant isolates were staphylococcus aureus and micrococcus luteus which were subjected to sublethal doses of 15 and 20 KGY respectively. The dose response curves of the 2 most radioresistant isolates showed simple exponential relationship. The D 10-value of S. aureus and M. luteus were 0.9 and 1.1 KGY, respectively. The effect of storage period on the bacterial load of, as well as, the antibacterial activity of the tested spices were investigated. (author)

Female ACI rats were given either control diet (AIN 93M or diet supplemented with 7.5% (w/w of anise, caraway, or celery seed powder. Two weeks later, one half of the animals in each group received subcutaneous silastic implants of E2. Diet intake and body weight were recorded weekly, and animals were euthanized after 3 and 12 weeks. E2-treatment showed significantly (2.1- and 3.4-fold enhanced growth of pituitary gland at 3 and 12 weeks, respectively. All test spices significantly offset the pituitary growth by 12 weeks, except celery which was effective as early as three weeks. Immunohistochemical analysis for proliferative cell nuclear antigen (PCNA in mammary tissues showed significant reduction in E2-mediated mammary cell proliferation. Test spices reduced the circulating levels of both E2 and prolactin at three weeks. This protection was more pronounced at 12 weeks, with celery eliciting the highest effect. RT-PCR and western blot analysis were performed to determine the potential molecular targets of the spices. Anise and caraway diets significantly offset estrogen-mediated overexpression of both cyclin D1 and estrogen receptor α (ERα. The effect of anise was modest. Likewise, expression of CYP1B1 and CYP1A1 was inhibited by all test spices. Based on short-term molecular markers, caraway was selected over other spices based on its enhanced effect on estrogen-associated pathway. Therefore, a tumor-end point study in ACI rats was conducted with dietary caraway. Tumor palpation from 12 weeks onwards revealed tumor latency of 29 days in caraway-treated animals compared with first tumor appearance at 92

  4. Application Of Electronic Nose And Ion Mobility Spectrometer To Quality Control Of Spice Mixtures

    Banach, U.; Tiebe, C.; Huebert, Th.

    2009-01-01

    The aim of the paper is to demonstrate the application of electronic nose (e-nose) and ion mobility spectrometry (IMS) to quality control and to find out product adulteration of spice mixtures. Therefore the gaseous head space phase of four different spice mixtures (spices for sausages and saveloy) was differed from original composition and product adulteration. In this set of experiments metal-oxide type e-nose (KAMINA-type) has been used, and characteristic patterns of data corresponding to various complex odors of the four different spice mixtures were generated. Simultaneously an ion mobility spectrometer was coupled also to an emission chamber for the detection of gaseous components of spice mixtures. The two main methods that have been used show a clear discrimination between the original spice mixtures and product adulteration could be distinguished from original spice mixtures.

  5. Validating SPICES as a Screening Tool for Frailty Risks among Hospitalized Older Adults

    Aronow, Harriet Udin; Borenstein, Jeff; Haus, Flora; Braunstein, Glenn D.; Bolton, Linda Burnes

    2014-01-01

    Older patients are vulnerable to adverse hospital events related to frailty. SPICES, a common screening protocol to identify risk factors in older patients, alerts nurses to initiate care plans to reduce the probability of patient harm. However, there is little published validating the association between SPICES and measures of frailty and adverse outcomes. This paper used data from a prospective cohort study on frailty among 174 older adult inpatients to validate SPICES. Almost all patients met one or more SPICES criteria. The sum of SPICES was significantly correlated with age and other well-validated assessments for vulnerability, comorbid conditions, and depression. Individuals meeting two or more SPICES criteria had a risk of adverse hospital events three times greater than individuals with either no or one criterion. Results suggest that as a screening tool used within 24 hours of admission, SPICES is both valid and predictive of adverse events. PMID:24876954

    Significant lead poisoning has been associated with imported nonpaint products. To describe cases of pediatric lead intoxication from imported Indian spices and cultural powders, determine lead concentrations in these products, and predict effects of ingestion on pediatric blood lead levels (BLLs). Cases and case-study information were obtained from patients followed by the Pediatric Environmental Health Center (Children's Hospital Boston). Imported spices (n = 86) and cultural powders (n = 71) were analyzed for lead by using x-ray fluorescence spectroscopy. The simple bioaccessibility extraction test was used to estimate oral bioavailability. The integrated exposure uptake biokinetic model for lead in children was used to predict population-wide geometric mean BLLs and the probability of elevated BLLs (>10 microg/dL). Four cases of pediatric lead poisoning from Indian spices or cultural powders are described. Twenty-two of 86 spices and foodstuff products contained >1 microg/g lead (for these 22 samples, mean: 2.6 microg/g [95% confidence interval: 1.9-3.3]; maximum: 7.6 microg/g). Forty-six of 71 cultural products contained >1 microg/g lead (for 43 of these samples, mean: 8.0 microg/g [95% confidence interval: 5.2-10.8]; maximum: 41.4 microg/g). Three sindoor products contained >47% lead. With a fixed ingestion of 5 microg/day and 50% bioavailability, predicted geometric mean BLLs for children aged 0 to 4 years increased from 3.2 to 4.1 microg/dL, and predicted prevalence of children with a BLL of >10 microg/dL increased more than threefold (0.8%-2.8%). Chronic exposure to spices and cultural powders may cause elevated BLLs. A majority of cultural products contained >1 microg/g lead, and some sindoor contained extremely high bioaccessible lead levels. Clinicians should routinely screen for exposure to these products.

The study variables included demographic profile, spice use behavior, perceptions about efficacy of spices, and willingness to use spices. Data were analyzed using SPSS to compute descriptive (e.g. percent and frequencies) and inferential statistics (i.e. logistic regression analyses). Results: Almost half of the participants were interested in learning about health benefits of spices (48%), indicated friends and family members as sources of information on spices (50%),and were willing to use spices as CAM therapies (51%). Most (>50%) of the participants were familiar with or had used eight out of the 10 listed spices. The majority of participants (54%)were currently using one or more spices on a daily basis and believed that ginger (64%), garlic(58%), and cinnamon (56%) could promote good health and wellness. In logistic regression analysis, age, gender (odds ratios [OR] = 1.44 and OR = 1.56), income (OR = 1.77), health status(OR = 2.01), and recommendations from healthcare providers (OR = 5.31 and OR = 3.96) were significant predictors of current spice use and willingness to use spices. Conclusion: Individuals in our study did not use many ethnic spices and were unaware of potential health benefits of spices. Greater awareness of ethnic spices for disease prevention and health promotion are needed in this population.

    2012-05-01

    Full Text Available Abstract Background A latent behavior of a biological cell is complex. Deriving the underlying simplicity, or the fundamental rules governing this behavior has been the Holy Grail of systems biology. Data-driven prediction of the system components and their component interplays that are responsible for the target system’s phenotype is a key and challenging step in this endeavor. Results The proposed approach, which we call System Phenotype-related Interplaying Components Enumerator (Spice, iteratively enumerates statistically significant system components that are hypothesized (1 to play an important role in defining the specificity of the target system’s phenotype(s; (2 to exhibit a functionally coherent behavior, namely, act in a coordinated manner to perform the phenotype-specific function; and (3 to improve the predictive skill of the system’s phenotype(s when used collectively in the ensemble of predictive models. Spice can be applied to both instance-based data and network-based data. When validated, Spice effectively identified system components related to three target phenotypes: biohydrogen production, motility, and cancer. Manual results curation agreed with the known phenotype-related system components reported in literature. Additionally, using the identified system components as discriminatory features improved the prediction accuracy by 10% on the phenotype-classification task when compared to a number of state-of-the-art methods applied to eight benchmark microarray data sets. Conclusion We formulate a problem—enumeration of phenotype-determining system component interplays—and propose an effective methodology (Spice to address this problem. Spice improved identification of cancer-related groups of genes from various microarray data sets and detected groups of genes associated with microbial biohydrogen production and motility, many of which were reported in literature.

  17. A review on spices. Present status of decontamination techniques such as gamma irradiation

    Gottschalk, H.M.

    1977-01-01

    The problem of flavour-preserving conservation of spices is described and discussed with a view to their use in the food industry. A number of possible ways of spice and spice extract conservation are presented. The main problem in spice conservation is the removal of contaminating microorganisms without loss or adulteration of taste. The number of microorganisms in spices is about 10 3 to 10 8 per g spice. Among these are soil microorganisms such as aerobic spoilage organisms, spore-formers, proteolytic and gas-producing bacteria. The incorporation of 0.1-1% spices into meat products may lead to a contamination of 10 5 to 10 6 organisms/g product. Extracted spice oils, on the other hand, are free of microorganisms. A number of physical and chemical sterilisation techniques are proposed. Radiosterilisation, in particular by means of gamma rays, is dealt with in detail. Here, a dose of 0.33 to 1.5 Mrad will kill the vegetative microorganisms, and complete sterilisation is achieved at 1.5 to 2.5 Mrad. Combination with heat or chemicals may bring about a 20% reduction in the amount of ionizing radiation required. There were no quality losses in the spices. Legalisation of ionizing radiation for spice conservation will require further tests of safety to be carried out. (AJ) [de

  19. Analysis of ESR measurement parameters for detecting irradiated spices

    Kameya, Hiromi; Hagiwara, Shoji; Todoriki, Setsuko

    2015-01-01

    The side signals from irradiated cellulose radical are used for detecting irradiated spices with the electron spin resonance (ESR). The side signals are two signals observed on both sides of a singlet signal (g≒2.00) from organic free radicals. Since the intensities of the side signals are weak, if the width of the singlet signal is large, these signals are covered and cannot be observed. In this study, we analyzed ESR measurement parameters of seven kinds spices (oregano, basil, parsley, coriander, cumin, white pepper, and black pepper) that would lead to narrow width of the singlet signal for detecting side signals. The results were as follows: 4 mW microwave power for basil, parsley, oregano, coriander, and cumin, and 8 mW for white pepper and black pepper, while modulation amplitude of 4 G, time constant of 20 ms were determined to be the optimal ESR measurement parameters.

    The growing number of Alzheimer's disease (AD) patients prompted us to seek effective natural resources for the prevention of AD. We focused on the inhibition of β-secretase, which is known to catalyze the production of senile plaque. Sixteen spices used in Asian countries were selected for the screening. Among the extracts tested, hexane extracts obtained from turmeric, cardamom, long pepper, cinnamon, Sichuan pepper, betel, white turmeric and aromatic ginger showed potent inhibitory activities. Their active principles were identified as sesquiterpenoids, monoterpenoids, fatty acid derivatives and phenylpropanoids using GC-MS analyses. The chemical structures and IC50 values of the compounds are disclosed. The results suggest that long-term consumption'of aromatic compounds from spices could be effective in the prevention of AD.

    The influence of the particle size of poly minerals in the signals of the thermally stimulated luminescence (TL) is analysed. The poly minerals were extracted of Mexican spices such as Origanum vulgare L. (origanum) and Capsicum annum (Chilli guajillo), these underwent to an homogenization process to obtain four different particle sizes corresponding to 149, 74, 53 and 10 {mu} m, and later on to expose them to gamma radiation in an interval of 0.5- 45 kGy in the Gamma beam 651 PT of {sup 60} Co irradiator of the Nuclear Sciences Institute, UNAM. The glow curves show a maximum of TL intensity for Capsicum annum to dose of 0.5- 10 kGy with particle size selected by means of a mesh of opening of 53 {mu} m, while for Origanum vulgare L., the more intense emission is observed with 149 {mu} m. In the interval of dose 12- 45 kGy the maximum in intensity emission it was presented in 53 {mu} m in both cases. For the case of 10 {mu} m, the TL emissions were of smaller intensity, and were achieved glow curves in a clear, defined way and an overlapping that allows to center the maximum of TL emission, in a defined temperature 126 C for Origanum vulgare L., and 166 C for Capsicum annum. The behavior before described is related with the composition of the samples. For Capsicum annum it was found Quartz (60%), Albite (30%) and Ortosa (10%), while Origanum vulgare stops L., Quartz (50%), Calcite (20%), Albite (20%) and Clay (10%). The homogenization of the samples is an important factor because exists high probability of avoiding as much as possible rests of organic matter traces that can contribute to the total signal of the glow curves. Likewise the defects that pollute from a natural way to each one of the minerals found in the samples, they play an outstanding role in the TL emissions. Although to the interacting the gamma radiation with the poly minerals of different particle sizes, there is a certain energy transfer that will be translated in the absorbed dose and this it

  5. SPICE Module for the Satellite Orbit Analysis Program (SOAP)

    Coggi, John; Carnright, Robert; Hildebrand, Claude

    2008-01-01

    A SPICE module for the Satellite Orbit Analysis Program (SOAP) precisely represents complex motion and maneuvers in an interactive, 3D animated environment with support for user-defined quantitative outputs. (SPICE stands for Spacecraft, Planet, Instrument, Camera-matrix, and Events). This module enables the SOAP software to exploit NASA mission ephemeris represented in the JPL Ancillary Information Facility (NAIF) SPICE formats. Ephemeris types supported include position, velocity, and orientation for spacecraft and planetary bodies including the Sun, planets, natural satellites, comets, and asteroids. Entire missions can now be imported into SOAP for 3D visualization, playback, and analysis. The SOAP analysis and display features can now leverage detailed mission files to offer the analyst both a numerically correct and aesthetically pleasing combination of results that can be varied to study many hypothetical scenarios. The software provides a modeling and simulation environment that can encompass a broad variety of problems using orbital prediction. For example, ground coverage analysis, communications analysis, power and thermal analysis, and 3D visualization that provide the user with insight into complex geometric relations are included. The SOAP SPICE module allows distributed science and engineering teams to share common mission models of known pedigree, which greatly reduces duplication of effort and the potential for error. The use of the software spans all phases of the space system lifecycle, from the study of future concepts to operations and anomaly analysis. It allows SOAP software to correctly position and orient all of the principal bodies of the Solar System within a single simulation session along with multiple spacecraft trajectories and the orientation of mission payloads. In addition to the 3D visualization, the user can define numeric variables and x-y plots to quantitatively assess metrics of interest.

    Modeling of superconducting nanowire single-photon detectors typically requires custom simulations or finite-element analysis in one or two dimensions. Here, we demonstrate two simplified one-dimensional SPICE models of a superconducting nanowire that can quickly and efficiently describe the electrical characteristics of a superconducting nanowire. These models may be of particular use in understanding alternative architectures for nanowire detectors and readouts.

    The 9.50 GHz electron paramagnetic resonance (EPR) spectra of unirradiated and 60 Co γ-ray irradiated cardamom (Elettaria cardamomum L. Maton, Zingiberaceae), ginger ((Zingiber officinale Rosc., Zingiberaceae), and saffron (Crocus sativus L., Iridaceae) have been investigated at room temperature. All unirradiated spices presented a weak resonance line with g-factors around free-electron ones. After γ-ray irradiation at an absorbed dose of up to 11.3 kGy, the presence of EPR spectra whose amplitude increase monotonously with the absorbed dose has been noticed with all spices. A 100 o C isothermal annealing of 11.3 kGy irradiated samples has shown a differential reduction of amplitude of various components that compose initial spectra, but even after 3.6 h of thermal treatment, the remaining amplitude represents no less then 30% of the initial ones. The same peculiarities have been noticed after 83 days storage at room temperature but after 340 days storage at ambient conditions only irradiated ginger displays a weak signal that differs from those of unirradiated sample. All these factors could be taken into account in establishing at which extent the EPR is suitable to evidence any irradiation treatment applied to these spices

    2012-01-01

    Extensive research within the last half a century has revealed that cancer is caused by dysregulation of as many as 500 different gene products. Most natural products target multiple gene products and thus are ideally suited for prevention and treatment of various chronic diseases, including cancer. Dietary agents such as spices have been used extensively in the Eastern world for a variety of ailments for millennia, and five centuries ago they took a golden journey to the Western world. Various spice-derived nutraceuticals, including 1′-acetoxychavicol acetate, anethole, capsaicin, car-damonin, curcumin, dibenzoylmethane, diosgenin, eugenol, gambogic acid, gingerol, thymoquinone, ursolic acid, xanthohumol, and zerumbone derived from galangal, anise, red chili, black cardamom, turmeric, licorice, fenugreek, clove, kokum, ginger, black cumin, rosemary, hop, and pinecone ginger, respectively, are the focus of this review. The modulation of various transcription factors, growth factors, protein kinases, and inflammatory mediators by these spice-derived nutraceuticals are described. The anticancer potential through the modulation of various targets is also the subject of this review. Although they have always been used to improve taste and color and as a preservative, they are now also used for prevention and treatment of a wide variety of chronic inflammatory diseases, including cancer.

    Prasad, Sahdeo; Tyagi, Amit K

    2016-01-01

    Spice and spice-derived compounds have been identified and explored for their health benefits since centuries. One of the spice long pepper has been traditionally used to treat chronic bronchitis, asthma, constipation, gonorrhea, paralysis of the tongue, diarrhea, cholera, malaria, viral hepatitis, respiratory infections, stomach ache, diseases of the spleen, cough, and tumors. In this review, the evidences for the chemopreventive and chemotherapeutic potential of piperlongumine have been described. The active component piperlonguime has shown effective against various ailments including cancer, neurogenerative disease, arthritis, melanogenesis, lupus nephritis, and hyperlipidemic. These beneficial effects of piperlongumine is attributed to its ability to modulate several signaling molecules like reactive oxygen species, kinases, proteasome, proto-oncogenes, transcription factors, cell cycle, inflammatory molecules and cell growth and survival molecules. Piperlongumine also chemosensitizes to drugs resistant cancer cells. Overall the consumption of long peppers is therefore recommended for the prevention and treatment of various diseases including cancer, and thus piperlongumine may be a promising future candidate drug against cancer.

  16. Lumped element modelling of superconducting circuits with SPICE

    Baveco, Maurice Antoine

    2015-01-01

    In this project research is carried out aimed at benchmarking a general-purpose circuit simulation software tool (”SPICE”). The project lasted for 8 weeks, from 29 June 2015 until 21 August 2015 at Performance Evaluation section at CERN. The goal was to apply it on a model of superconducting magnets, namely the main dipole circuit (RB circuit) of the the LHC (Large Hadron Collider), developed by members of the section. Then the strengths and the flaws of the tool were investigated. Transient effects were the main simulation focus point. In the first stage a simplified RB circuit was modelled in SPICE based on subcircuits. The first results were promising but still not with a perfect agreement. After implementing more detailed subcircuits there is an improvement and promising agreement achieved between SPICE and the results of the paper (PSpice) [2]. In general there are more strengths than drawbacks of simulating with SPICE. For example, it should have a shorter simulation time than PSpice for the same mo...

  17. FDTD-SPICE for Characterizing Metamaterials Integrated with Electronic Circuits

    Zhengwei Hao

    2012-01-01

    Full Text Available A powerful time-domain FDTD-SPICE simulator is implemented and applied to the broadband analysis of metamaterials integrated with active and tunable circuit elements. First, the FDTD-SPICE modeling theory is studied and details of interprocess communication and hybridization of the two techniques are discussed. To verify the model, some simple cases are simulated with results in both time domain and frequency domain. Then, simulation of a metamaterial structure constructed from periodic resonant loops integrated with lumped capacitor elements is studied, which demonstrates tuning resonance frequency of medium by changing the capacitance of the integrated elements. To increase the bandwidth of the metamaterial, non-Foster transistor configurations are integrated with the loops and FDTD-SPICE is applied to successfully bridge the physics of electromagnetic and circuit topologies and to model the whole composite structure. Our model is also applied to the design and simulation of a metasurface integrated with nonlinear varactors featuring tunable reflection phase characteristic.

    2016-01-01

    Full Text Available La relación de dependencia demográfica es una medida de la carga de dependencia demográfica muy difundida. Dentro de la bibliografía relacionada se presupone una relación inversa entre este indicador y el crecimiento económico de un país; sin embargo, se destaca la carencia de especificaciones conceptuales y teóricas que respondan acerca de este vínculo. Sólo se detallan definiciones operativas sobre su forma de cálculo, en base a un criterio estrictamente biológico, estableciendo que todas las personas entre 14 y 64 años inclusive son potenciales activos (sin distinción, mientras que la población fuera de este rango de edad es considerada potencialmente inactiva o dependiente. La hipótesis propuesta es que la relación de dependencia demográfica resulta un indicador insuficiente para estimar la carga real de dependencia económica, debido a que no considera la dinámica real del mercado laboral. Se toman dos índices complementarios propuestos por Chackiel (2000 para cuantificar la subvaluación de la carga de dependencia demográfica. La fuente utilizada corresponde a los censos nacionales de población de los años 2001 y 2010 de Argentina, que reflejan periodos opuestos en términos de capacidad de absorción de mano de obra y sensibilidad de la población a participar en la actividad económica.

  3. Spices: the savory and beneficial science of pungency.

    Nilius, Bernd; Appendino, Giovanni

    2013-01-01

    Spicy food does not only provide an important hedonic input in daily life, but has also been anedoctically associated to beneficial effects on our health. In this context, the discovery of chemesthetic trigeminal receptors and their spicy ligands has provided the mechanistic basis and the pharmacological means to investigate this enticing possibility. This review discusses in molecular terms the connection between the neurophysiology of pungent spices and the "systemic" effects associated to their trigeminality. It commences with a cultural and historical overview on the Western fascination for spices, and, after analysing in detail the mechanisms underlying the trigeminality of food, the main dietary players from the transient receptor potential (TRP) family of cation channels are introduced, also discussing the "alien" distribution of taste receptors outside the oro-pharingeal cavity. The modulation of TRPV1 and TRPA1 by spices is next described, discussing how spicy sensations can be turned into hedonic pungency, and analyzing the mechanistic bases for the health benefits that have been associated to the consumption of spices. These include, in addition to a beneficial modulation of gastro-intestinal and cardio-vascular function, slimming, the optimization of skeletal muscle performance, the reduction of chronic inflammation, and the prevention of metabolic syndrome and diabetes. We conclude by reviewing the role of electrophilic spice constituents on cancer prevention in the light of their action on pro-inflammatory and pro-cancerogenic nuclear factors like NFκB, and on their interaction with the electrophile sensor protein Keap1 and the ensuing Nrf2-mediated transcriptional activity. Spicy compounds have a complex polypharmacology, and just like any other bioactive agent, show a balance of beneficial and bad actions. However, at least for moderate consumption, the balance seems definitely in favour of the positive side, suggesting that a spicy diet, a caveman

  4. Commercial potential of irradiated spices and dried mixes for export and domestic markets

    Padwal-Desai, S.R.

    1994-01-01

    Indian traders who are conventionally exporting non-sterile spices and other dry mixes to several countries, receive not only low value for their produce on account of poor microbiological quality, but also lose the benefits of value addition. Development of gamma ray hygienization facility at the export points could therefore change this scenario. The economic benefits of hygienization and value addition could justifiably be accrued by the spice producing nations like India which has the necessary expertise and technology for supplying quality spices and spice mixes to the world class consumer, besides providing quality product to a huge domestic market. 10 refs

  5. Comparison of electron-irradiation and gamma-irradiation as a decontamination treatment of spices

    Hayashi, Toru; Todoriki, Setsuko; Mamun.

    1993-01-01

    Electron-irradiation at 10 kGy decontaminated all the eight kinds of spices (black pepper, white pepper, nutmeg, red pepper, parsley, paprika, laurel and onion powder) to the microbial levels lower than 10 2 /g. Similar sterilization effects by the irradiation were observed on heat-resistant bacterial spores. The 10 kGy irradiation did not significantly affect the contents of essential oils and colors of the spices. These results indicate that electron-irradiation at 10 kGy effectively decontaminates spices without notable adverse effect on the qualities. The disinfecting effect of electron beams on spices was smaller than that of gamma-rays. (author)

    1993-09-01

    About 3 and 9 months after irradiation 14 laboratories determined the thermoluminescence (TL) of mineral contaminations which were isolated from different coded spice-and-herb products. In both study periods 99% of the 317 samples (total number) were correctly identified as irradiated or non-irradiated on the basis of normalized TL intensities. Only three irradiated samples were not identified as irradiated. The results show that irradiation of spices, herbs and spice-and-herb mixtures can be clearly detected throughout the entire period in which the products are normally stored, and that the method is suitable for routine analysis in food control laboratories.

    SPICE is an imaging spectrometer operating at vacuum ultraviolet (VUV) wavelengths, 70.4 - 79.0 nm and 97.3 - 104.9 nm. It is a facility instrument on the Solar Orbiter mission, which carries 10 science instruments in all, to make observations of the Sun's atmosphere and heliosphere, at close proximity to the Sun, i.e to 0.28 A.U. at perihelion. SPICE's role is to make VUV measurements of plasma in the solar atmosphere. SPICE is designed to achieve spectral imaging at spectral resolution >1500, spatial resolution of several arcsec, and two-dimensional FOV of 11 x16arcmins. The many strong constraints on the instrument design imposed by the mission requirements prevent the imaging performance from exceeding those of previous instruments, but by being closer to the sun there is a gain in spatial resolution. The price which is paid is the harsher environment, particularly thermal. This leads to some novel features in the design, which needed to be proven by ground test programs. These include a dichroic solar-transmitting primary mirror to dump the solar heat, a high in-flight temperature (60deg.C) and gradients in the optics box, and a bespoke variable-line-spacing grating to minimise the number of reflective components used. The tests culminate in the systemlevel test of VUV imaging performance and pointing stability. We will describe how our dedicated facility with heritage from previous solar instruments, is used to make these tests, and show the results, firstly on the Engineering Model of the optics unit, and more recently on the Flight Model.

  12. Detection of irradiated spices with a microbiological method - DEFT/APC method

    Hammerton, K.M.; Banos, C.

    1996-01-01

    The decontamination of spices that are to be used as ingredients in processed foods is necessary in order to prevent the introduction of spoilage microorganisms and more rarely disease causing organisms. Spices can be contaminated with bacteria and moulds in concentration from 10 3 to 10 8 microorganisms per gram so that, even when used in small amounts, they can contaminate food with large numbers of microorganisms. The most effective means of decontaminating spices is irradiation treatment with an absorbed radiation dose from 5 to 10 kGy. Several countries are commercially using radiation processing of spices. A microbiological screening method based on the use of the direct epifluorescent filter technique (DEFT) and the conventional aerobic plate count (APC) has been established for the detection of irradiated spices. The DEFT count enumerates the total number of contaminating microorganisms, irrespective of viability, in an untreated or treated spice sample. This paper reports recent investigations on the possibility that the inclusion of a mesophilic aerobic spore count will enable irradiated spices to be distinguished from ethylene oxide (EtO) or heat treated spices.

  13. Postharvest Processing and Benefits of Black Pepper, Coriander, Cinnamon, Fenugreek, and Turmeric Spices.

    Balasubramanian, S; Roselin, P; Singh, K K; Zachariah, John; Saxena, S N

    2016-07-26

    Spices are prime source for flavor, aroma, and taste in cuisines and play an active role as medicines due to their high antioxidant properties. As medicine or food, the importance of spices cannot be overemphasized. The medicinal values of spices are very well established in treating various ailments like cancer, fever, malaria, stomach offset, nausea, and many more. A spice may be available in several forms: fresh, whole dried, or pre-ground dried which requires further processing to be utilized in the form of value-added product. This review paper deals with the cultivation, postharvesting, chemical composition, uses, health, and medicinal benefits of the selected spice viz., black pepper, coriander, cinnamon, fenugreek, turmeric, and technological advances in processing of spices viz., super critical fluid extraction, cryogenic grinding, and microencapsulation etc. This paper also focuses on issues related to utilization of spices toward its high end-product development and characterization in pharmaceuticals and other medicinal purposes. The availability of different spices and their varietal differences and location have their pertinent characters, which are much demanding to refine postharvest and processing to assure its quality in the international market.

  14. Gastrointestinal protective effect of dietary spices during ethanol-induced oxidant stress in experimental rats.

    Prakash, Usha N S; Srinivasan, Krishnapura

    2010-04-01

    Spices are traditionally known to have digestive stimulant action and to cure digestive disorders. In this study, the protective effect of dietary spices with respect to activities of antioxidant enzymes in gastric and intestinal mucosa was examined. Groups of Wistar rats were fed for 8 weeks with diets containing black pepper (0.5%), piperine (0.02%), red pepper (3.0%), capsaicin (0.01%), and ginger (0.05%). All these spices significantly enhanced the activities of antioxidant enzymes--superoxide dismutase, catalase, glutathione reductase, and glutathione-S-transferase--in both gastric and intestinal mucosa, suggesting a gastrointestinal protective role for these spices. In a separate study, these dietary spices were found to alleviate the diminished activities of antioxidant enzymes in gastric and intestinal mucosa under conditions of ethanol-induced oxidative stress. The gastroprotective effect of the spices was also reflected in their positive effect on mucosal glycoproteins, thereby lowering mucosal injury. The amelioration of the ethanol-induced decrease in the activities of antioxidant enzymes in gastric and intestinal mucosa by dietary spices suggests their beneficial gastrointestinal protective role. This is the first report on the gastrointestinal protective potential of dietary spices.

    Anaerobic digestion (AD) of kitchen waste (KW) for biogas production is a major challenge to all over the world due to significant compositional variations in KW, such as different types and quantities of spices used for preparing food. Spices may affect the AD process owing to their antimicrobial activity. In this paper, the effect of spices (garlic, red chili, cinnamon, coriander, clove, turmeric, cardamom, black pepper) on AD of KW has been investigated. Batch experiments were carried out to determine the maximum biogas production potential, methane production rate and lag phase for biogas production. Analysis of the results revealed different magnitude of inhibition of the AD process of KW in the presence of different spices. Cinnamon, cardamom and clove resulted >85%, black pepper resulted 75%, while coriander, chili, turmeric and garlic resulted 55-70% reduction in cumulative biogas yield. Elemental analysis showed high concentration of heavy metals in the spices, which along with other bioactive components of the spices could be responsible for the inhibitory effect of the spices on biomethanation. Microbial examination of the digestate also showed a decrease in population of fermentative and methanogenic bacteria in the presence of spices. Copyright © 2017 Elsevier Ltd. All rights reserved.

  16. Molecular Targets of Nutraceuticals Derived from Dietary Spices: Potential Role in Suppression of Inflammation and Tumorigenesis

    Aggarwal, Bharat B.; Van Kuiken, Michelle E.; Iyer, Laxmi H.; Harikumar, Kuzhuvelil B.; Sung, Bokyung

    2011-01-01

    Despite the fact cancer is primarily a preventable disease, recent statistics indicate cancer will become the number one killer worldwide in 2010. Since certain cancers are more prevalent in the people of some countries than others, suggests the role of lifestyle. For instance cancer incidence among people from the Indian subcontinent, where most spices are consumed, is much lower than that in the Western World. Spices have been consumed for centuries for a variety of purposes—as flavoring agents, colorants, and preservatives. However, there is increasing evidence for the importance of plant-based foods in regular diet to lowering the risk of most chronic diseases, so spices are now emerging as more than just flavor aids, but as agents that can not only prevent but may even treat disease. In this article, we discuss the role of 41 common dietary spices with over 182 spice-derived nutraceuticals for their effects against different stages of tumorigenesis. Besides suppressing inflammatory pathways, spice-derived nutraceuticals can suppress survival, proliferation, invasion, and angiogenesis of tumor cells. We discuss how spice-derived nutraceuticals mediate such diverse effects and what their molecular targets are. Overall our review suggests “adding spice to your life” may serve as a healthy and delicious way to ward off cancer and other chronic diseases. PMID:19491364

    Ana Crespo Solana

    2009-08-01

    Full Text Available This paper sets out to analyze the Junta de Dependencia de Extranjeros, an institution that was created within the framework of the government reforms that characterized the reign of Phillip V after the war of Spanish succession in order to monitor and control the activity of foreign merchants settled in numerous Spanish cities. During its operative period this institution developed a strong links and effective lines of communication with foreign merchant communities resident in Spain. This study is based on primary sources such as the documentation generated by the Junta, which included requests and complaints lodged by merchants and merchant communities as well as reports on the appointment of foreign consuls. These sources are preserved in the State sections of the Archivo Histórico Nacional de Madrid and the Archivo General de Simancas. The correspondence of the representatives of merchant communities in Spain has also been used, as well as affidavits and population censuses preserved in the Provincial Archives of Madrid, Cadiz and Murcia. These sources have been interrogated in order to establish the stances and discourses adopted by both the Spanish government and the foreign merchants settled in those cities that sent representatives to the offices of Spain’s central government. The requests and complaints filed by foreign merchants and consuls in this context demonstrate the strength of their communities, which had been granted substantial privileges during the second half of the seventeenth century, and to which the Junta responded with a high degree of understanding. The Junta’s conciliatory stance was linked not only to pressure exerted by foreign ambassadors, but also to limitations established by the peace treaties signed by Spain. The Junta de Dependencia de Extranjeros clearly adopted a radically different position to that of Charles II’s fiercely protectionist government, and generally responded favourably to requests from

    2003-12-01

    The changes in spice paprika powder induced by ionizing radiation, saturated steam (SS) and their combination were studied as a function of the absorbed radiation dose and the storage time. The SS treatment lead to a decrease in color content (lightening) after 12 weeks of storage, together with the persistence of free radicals and viscosity changes for a longer period. The results suggest that ionizing radiation is a more advantageous method as concerns preservation of the quality of spice paprika.

    Three spice mill workers developed work-related allergy and asthma after prolonged exposure to high levels (>10 mg/m(3)) of inhalable spice dust. Patterns of sensitization to a variety of spices and putative allergens were identified. Work-related allergy and asthma were assessed on history, clinical evaluation, pulmonary function and fractional exhaled nitric oxide. Specific IgE reactivity to a range of common inhalant, food and spice allergens was evaluated using ImmunoCAP and allergen microarray. The presence of non-IgE-mediated reactions was determined by basophil stimulation (CAST-ELISA). Specific allergens were identified by immunoblotting to extracts of raw and dried processed garlic, onion and chili pepper. Asthma was confirmed in all 3 subjects, with work-related patterns prominent in worker 1 and 3. Sensitization to multiple spices and pollen was observed in both atopic workers 1 and 2, whereas garlic and chili pepper sensitization featured in all 3 workers. Microarray analysis demonstrated prominent profilin reactivity in atopic worker 2. Immunoblotting demonstrated a 50-kDa cross-reactive allergen in garlic and onion, and allergens of approximately 40 and 52 kDa in chili pepper. Dry powdered garlic and onion demonstrated greater IgE binding. This study demonstrated IgE reactivity to multiple spice allergens in workers exposed to high levels of inhalable spice dust. Processed garlic and onion powder demonstrated stronger IgE reactivity than the raw plant. Atopy and polysensitization to various plant profilins, suggesting pollen-food syndrome, represent additional risk factors for sensitizer-induced work-related asthma in spice mill workers. 2010 S.

    Full Text Available For centuries, spices have been consumed as food additives or medicinal agents. However, there is increasing evidence indicating the plant-based foods in regular diet may lower the risk of neurodegenerative diseases including Alzheimer disease. Spices, as one of the most commonly used plant-based food additives may provide more than just flavors, but as agents that may prevent or even halt neurodegenerative processes associated with aging. In this article, we review the role and application of five commonly used dietary spices including saffron turmeric, pepper family, zingiber, and cinnamon. Besides suppressing inflammatory pathways, these spices may act as antioxidant and inhibit acetyl cholinesterase and amyloid β aggregation. We summarized how spice-derived nutraceuticals mediate such different effects and what their molecular targets might be. Finally, some directions for future research are briefly discussed.

  9. Using the SPICE system to help plan and interpret space science observations

    Acton, Charles H., Jr.

    1993-01-01

    A portable multimission information system named SPICE is used to assemble, archive, and provide easy user access to viewing geometry and other ancillary information needed by space scientists to interpret observations of bodies within our solar system. The modular nature of this system lends it to use in planning such observations as well. With a successful proof of concept on Voyager, the SPICE system has been adapted to the Magellan, Galileo and Mars Observer missions, and to a variety of ground based operations. Adaptation of SPICE for Cassini and the Russian Mars 94/96 projects is underway, and work on Cassini will follow, SPICE has been used to support observation planning for moving targets on the Hubble Space Telescope Project. Applications for SPICE on earth science, space physics and other astrophysics missions are under consideration.

    Different spices such as turmeric, oregano, and cinnamon were γ-irradiated at 1 and 10 kGy. The electron paramagnetic resonance (EPR) spectra of the nonirradiated samples were characterized by a single central signal (g = 2.006), the intensity of which was significantly enhanced upon irradiation. The EPR spectra of the irradiated spice samples were characterized by an additional triplet signal at g = 2.006 with a hyperfine coupling constant of 3 mT, associated with the cellulose radical. EPR analysis on various sample pretreatments in the irradiated spice samples demonstrated that the spectral features of the cellulose radical varied on the basis of the pretreatment protocol. Alcoholic extraction pretreatment produced considerable improvements of the EPR signals of the irradiated spice samples relative to the conventional oven and freeze-drying techniques. The alcoholic extraction process is therefore proposed as the most suitable sample pretreatment for unambiguous detection of irradiated spices by EPR spectroscopy.

    For the identification of irradiated food, current analysis methods have limitations regarding presence and stability of radiation-induced markers. In this study, different spice blends with small quantity of different irradiated (0, 1 and 10 kGy) spice powders, such as red pepper, garlic or ginger, were investigated using PSL and TL techniques. In PSL-based screening analysis, the spice blends containing 10% of irradiated materials (1 or 10 kGy) were determined as intermediate or positive. In TL results, the blends containing 1% of 1 or 10 kGy-irradiated spices showed the typical TL glow curves that could be interpreted as positive. The blends with irradiated garlic powder provided more good results where identification was possible at 0.5% mixing of irradiated sample. However, the TL ratios of all spice blends were <0.1 and only TL glow curve shape and intensity may be used to discriminate the samples having irradiated component.

    Lysogenic Escherichia coli K12 strains Nos. GY 5023: envA uvr + (lambda) and GY 5027: envA uvrB (lambda) were used as test organisms and E.coli strain No. GY 4015 as the indicator to investigate prophage induction (Inductest) of blood samples of CFY rats fed with black pepper and spice mixture treated with gamma radiation. The dose levels applied for the irradiation of spices were 0.5 and 15 kGy. In the rat feed, the applied concentration of ground black pepper was 3.5%, and that of the spice mixture (: mild paprika, black pepper, allspice, coriander, marjoram, cumin and nutmeg) was 25%. Blood samples were taken for prophage induction after six days' feeding with the tested diet. Tests with pepper were performed both within two weaks after irradiation and again after 90 days of storage following irradiation, while with the spice mixture, Inductest was performed with the blood of rats fed with a spice mixture irradiated 90 days before the start of the feeding test. Neither the blood of rats fed with irradiated pepper nor that of rats fed with irradiated spice mixture did increase, to a statistically significant degree, the occurrence of prophage induction as compared with blood samples of rats fed with a diet containing untreated spices or with commercial rat feed. In agreement with earlier microbial mutagenicity tests performed with extracts of irradiated spices and urine of rats fed with irradiated spices, neither did the present results indicate that spices irradiated with 5 and 15 kGy or their metabolites would be of DNA-modofying potential.

  17. Radiation decontamination of three local spices and khebab spice-mix and some aspects of their physiochemical and nutritional properties before and after gamma irradiation

    Kottoh, D. I

    2011-07-01

    Spices are used for seasoning, garnishing and for their therapeutic or medicinal properties. In this thesis, three local spices namely, 'pepre' (E. caryophyllata), 'Fom wisa' (A. melegueta), 'whentia' (X. aethiopica) and khebab spice-mix were tested to ascertain their storage mycroflora and moisture isotherms under tropical Ghanaian environment at (Environmental Relative Humidities, ERH's of 20, 55, 65, 75, 85 and 95%) simulated by glycerol: water mixtures with view of ascertaining their storage stability and mouldiness potential. Mouldiness was determined by the decimal serial dilution technique up to 1:10 4 dilutions. As background data to ascertain the importance of the spices in the Ghanaian diet, a structured rapid appraisal questionnaire was designed to provide information on the types of spices, marketing strategies and social profile of the traders. The selected spices were packaged in three different packaging materials and treated with varying doses of gamma radiation (0, 5, 10 and 20kGy). Changes in the mycroflora and some selected physiochemical parameters (pH, %, moisture, fat, ash content, crude protein, total carbohydrates) were determined using standard conventional methods from (AOAC, 2000). Elemental composition of the products were examined using Neutron Activation Analysis (NAA). Finally, the consumer preference of the khebab spice - mix was assessed by sensory evaluation of attributes such as colour, taste, smell, mouthfeel and overall acceptability. A 2X3X4 factorial experiment in a complete Randomised Design was used for the study and data was subjected to statistical analysis using microsoft Excel and Genstats softwares. Analysis was evaluated based on p<0.05 level of significance. The sellers of spices were between 10 - 70 years, but majority were between 30 - 40 years. Spices in the Accra markets were received from seven regions in Ghana and some were imported from West Africa and other foreign countries. The resident microflora in the

    The X-band EPR spectra of unirradiated and 60 Co gamma ray irradiated cardamom (Elettaria cardamomum L. Maton, Zingiberaceae), ginger ((Zingiber officinale Rosc., Zingiberaceae), saffron (Crocus sativus L., Iridaceae), and curry have been investigated at room temperature. All unirradiated spices presented a weak resonance line with g-factors around free-electron ones, most probably due to the presence of semiquinones, previously reported to have paramagnetic properties. After gamma ray irradiation at absorbed dose up to 11.3 kGy we have noticed in all spices the presence of complex EPR spectra consisting of a superposition of at last two different paramagnetic species whose amplitude increase monotonously with the absorbed dose. A 100 deg. C isothermal annealing of 11.3 kGy irradiated samples has shown a differential reduction of amplitude of various components that form the initial spectra, but even after 5 h of thermal treatment, the remaining amplitude represents no less than 40% from the initial ones, testifying for a good thermal stability. The presences of initial EPR spectra as well as the remaining amplitude after isothermal annealing are very useful in identifying any irradiation treatment applied to this category of species.

  19. A SPICE model of double-sided Si microstrip detectors

    Candelori, A.; Paccagnella, A.; Bonin, F.

    1996-01-01

    We have developed a SPICE model for the ohmic side of AC-coupled Si microstrip detectors with interstrip isolation via field plates. The interstrip isolation has been measured in various conditions by varying the field plate voltage. Simulations have been compared with experimental data in order to determine the values of the model parameters for different voltages applied to the field plates. The model is able to predict correctly the frequency dependence of the coupling between adjacent strips. Furthermore, we have used such model for the study of the signal propagation along the detector when a current signal is injected in a strip. Only electrical coupling is considered here, without any contribution due to charge sharing derived from carrier diffusion. For this purpose, the AC pads of the strips have been connected to a read-out electronics and the current signal has been injected into a DC pad. Good agreement between measurements and simulations has been reached for the central strip and the first neighbors. Experimental tests and computer simulations have been performed for four different strip and field plate layouts, in order to investigate how the detector geometry affects the parameters of the SPICE model and the signal propagation

  20. "Spice" (Synthetic Marijuana) Induced Acute Myocardial Infarction: A Case Series.

    Marijuana is the most widely abused "recreational" substance in the United States, with highest prevalence in young adults. It is reported to cause ischemic strokes, hepatitis, anxiety, and psychosis. Although it is associated with dose dependent tachycardia and can lead to coronary vasospasm, it has not been directly related to acute myocardial infarction (AMI). Marijuana induced coronary vasospasm can result in endothelial denudation at the site of a vulnerable atherosclerotic plaque in response to hemodynamic stressors, potentially causing an AMI. Spice refers to herbal mixture with composition and effects similar to that of marijuana and therefore is referred to as "synthetic marijuana." Herein, we report 3 cases of spice induced ST-segment elevation myocardial infarction. All patients were relatively young and had few or absolutely no risk factors for cardiovascular disease. All patients underwent emergent coronary angiography, with two needing stent placement and the third requiring only aspiration thrombectomy. Our case series emphasizes the importance of suspecting and investigating synthetic marijuana use in low risk young adults presenting with AMI.

    Formation of glycation products is major factor responsible in complications of diabetes. Worldwide trend is toward the use of natural additives in reducing the complications of diseases. Therefore, there is a growing interest in natural antiglycation found in plants. Herbs and spices are one of the most important targets to search for natural antiglycation from the point of view of safety. This study investigated the ability of some of the spices to inhibit glycation process in a hemoglobin/glucose model system and compared their potency with each other. For this subject the best concentration and time to incubate glucose with hemoglobin was investigated. Then the glycosylation degree of hemoglobin in the presence of extracts by the three concentrations 0.25, 0.5 and 1 μg/ml was measured colorimetrically at 520 nm. Results represent that some of extracts such as wild caraway, turmeric, cardamom and black pepper have inhibitory effects on hemoglobin glycation. But some of the extracts such as anise and saffron have not only inhibitory effects but also aggravated this event and have proglycation properties. In accordance with the results obtained we can conclude that wild caraway, turmeric, cardamom and black pepper especially wild caraway extracts are potent antiglycation agents, which can be of great value in the preventive glycation-associated complications in diabetes.

    The aim of this study was to identify fungal species present in 200 samples of rosemary, fennel, cinnamon, clove, pepperoni, black and white pepper and oregano and evaluate the mycotoxigenic potential of the some Aspergilli isolated. Clove, black and white peppers were analyzed by direct plating. For rosemary, cinnamon, fennel, pepperoni pepper and oregano samples were used spread plate. Mycotoxigenic capacity was verified by the agar plug method. With the exception of clove, all the spices showed high fungal contamination, especially by Aspergillus sp., Penicillium sp. and Cladosporium sp. Frequency of toxigenic Aspergillus spp. was intense in white and black peppers, with presence of Aspergillus flavus (up to 32%), Aspergillus nomius (up to 12%), Aspergillus parasiticus (up to 4%), Aspergillus niger complex (up to 52%), Aspergillus ochraceus (up 12%) and Aspergillus carbonarius (up to 4%). 14,2% of A. flavus isolated from black pepper were aflatoxins producers. In the white pepper, 66.7% of A. flavus isolates and 100% of A. nomius were aflatoxigenic. Oregano showed the highest number of A. niger complex isolates (49), however, only 2.04% produced ochratoxin A. This study showed a huge fungal presence in spices, which could compromise the sensorial quality of these products and represent a hazard for consumers. Copyright © 2018. Published by Elsevier Ltd.

  3. Radiosterilization or sterilization by steam. Procedures for sterilization of spices

    Warmbold, J.

    1994-01-01

    The article compares two different methods for the sterilization of spices, namely radiosterilization and sterilization with steam. The first method applies ionizing radiation which can alter the chemical composition of the products. Tests have shown, however, that radiation doses up to 10 kGy will not induce the formation of carcinogenic agents in the foodstuffs, or of toxic substances, and thus are a wholesome method of preservation. Any modifications of taste, color or smell, or loss of vitamins, can be avoided by proper dose control and standard irradiation conditions. Sterilization by steam is a method achieving substantial suppression of the formation of germs, aerobic spores, yeasts, mould, and gramnegative germs, while preserving in most cases the essential oils. It may result in sensoric alterations, i.e affect the color, smell or taste, but in general the spices thus treated preserved their characteristic properties. The method is a good alternative to radiosterilization. The article adds some concluding information on mandatory labelling of irradiated food imported from third countries

  5. AIDS in Mexican prisons.

    Olivero, J M; Roberts, J B

    1995-01-01

    The human rights organization Americas Watch, which toured Mexican prisons, reported in 1991 that all prisoners with HIV infection in the Mexico City area were housed in a single AIDS ward in Santa Marta Prison. In 1991, the 16-bed facility had 15 patients; in 1993, this number had increased by 5. In Mexico City, with 3 prisons holding over 2000 male adults each, there were only 20 known infected prisoners in the AIDS ward at Santa Marta. In 1991, authorities at Matamoros, in the state of Tamaulipas, insisted that none of their inmates had ever been diagnosed as infected with HIV. The prison physician at Reynosa indicated that only 2 inmates since 1985 had ever been diagnosed as infected. In 1992, the prison in Saltillo, in the state of Coahuila, reported that here had yet to be a single positive test for HIV. The prison at Reynosa held 1500 people and only 2 inmates were diagnosed as having AIDS between 1985 and 1991. Prisons at Matamoros and Saltillo held similar numbers but had no experience of infected inmates. A survey of 2 prisons in the state of Tamaulipas indicates that around 12% of the population may use IV drugs, and 9% indicate sharing needles. It is possible for prisoners to die of diseases like pneumonia, associated with AIDS, without the connection to AIDS being diagnosed. Each state, and possibly each prison in Mexico, has its own particular AIDS policies. Santa Marta was the single facility in Mexico City used to house AIDS-infected prisoners, who were segregated. Finally, the prison at Saltillo required all women entering the facility to have a medical examination, including a test for HIV. High-level prison personnel have demonstrated ignorance and fear of AIDS and intolerance of infected prisoners. Mexico must reassess the need to provide adequate medical care to offenders who are sick and dying behind bars.

  6. Mexican agencies reach teenagers.

    Brito Lemus, R; Beamish, J

    1992-08-01

    The Gente Joven project of the Mexican Foundation for Family Planning (MEXFAM) trains young volunteers in 19 cities to spread messages about sexually transmitted diseases and population growth to their peers. They also distribute condoms and spermicides. It also uses films and materials to spread its messages. The project would like to influence young men's behavior, but the Latin image of machismo poses a big challenge. It would like to become more responsible toward pregnancy prevention. About 50% of adolescents have sexual intercourse, but few use contraceptives resulting in a high adolescent pregnancy rate. Many of these pregnant teenagers choose not to marry. Adolescent pregnancy leads to girls leaving school, few marketable skills, and rearing children alone. Besides women who began childbearing as a teenager have 1.5 times more children than other women. Male involvement in pregnancy prevention should improve these statistics. As late as 1973, the Health Code banned promotion and sales of contraceptives, but by 1992 about 50% of women of reproductive age use contraceptives. The Center for the Orientation of Adolescents has organized 8 Young Men's Clubs in Mexico City to involve male teenagers more in family planning and to develop self-confidence. It uses a holistic approach to their development through discussions with their peers. A MEXFAM study shows that young men are not close with their fathers who tend to exude a machismo attitude, thus the young men do not have a role model for responsible sexual behavior. MEXFAM's work is cut out for them, however, since the same study indicates that 50% of the young men believe it is fine to have 1 girlfriend and 33% think women should earn more than men. A teenager volunteer reports, however, that more boys have been coming to him for contraception and information than girls in 1992 while in other years girls outnumbered the boys.

    Seven kinds of spices were irradiated with gamma-rays at the dose of 5 to 80 kGy. Studies of radiation effect on lipids in each spice were carried out by measuring peroxide value (POV), iodine value (IV), acid value (AV) and analysis of gas-chromatography (GC). POV in each spice was gradually increased with increasing absorbed doses. The increase of POV in nutmeg was higher than those of other spices, and it was suggested that those increase of POV values were related to lipid contents in spices. A little increase of IV and AV were also observed as same amount of POV by the irradiation up to 80 kGy. From the GC analysis of lipids in each spice, components were not changed even irradiated up to 50 kGy of gamma-rays. Radiation effect on components of essential oils in each spice were also analyzed by headspace-GC (HS-GC), and any degradation of components were not observed up to 50 kGy of irradiation even analyzed by GC after separation to hydrocarbon and oxygen compounds. On the contrary, essential oils of cloves sterilized by heat treatment were apparently decreased as compared with irradiated and non-irradiated cloves. (author).

    Bioactive components of many foods added during cooking have potential antioxidant, anti-inflammatory, antimicrobial, antibacterial and chemopreventive properties. However, epidemiologic studies generally do not collect detailed information on these items, which include spices, chilies, coconuts, garlic, onions, and oils. Since India has some of the highest spice consumption in the world, we developed a computer-based food preparer questionnaire to estimate per capita consumption of 19 spices, chilies, coconuts, garlic, onions, and 13 cooking oils among 3,625 participants in the India Health Study, a multicenter pilot study in three regions of India. We observed notable regional differences in consumption of spices, chilies, coconut, garlic, and onions. In Trivandrum, over 95 percent of the participants consumed 12 different spices, while in New Delhi and Mumbai, 95 percent of participants consumed only four and five spices, respectively. Cooking oil use also varied, as ghee was most common in New Delhi (96.8%) followed by mustard seed oil (78.0%), while in Trivandrum the primary oil was coconut (88.5%) and in Mumbai it was peanut (68.5%). There was some variation in consumption by education, income, and religion. Using a novel method for assessing food items primarly added during cooking, we successfully estimated per capita consumption within an epidemiologic study. Based on basic science research and suggestive ecologic level data on cancer incidence and spice consumption, improving epidemiologic assessment of these potentially chemopreventive food items may enhance our understanding of diet and cancer risk.

    Usually spices are identified morphologically using simple methods like magnifying glasses or microscopic instruments. On the other hand, molecular biological methods like the polymerase chain reaction (PCR) enable an accurate and specific detection also in complex matrices. Generally, the origins of spices are plants with diverse genetic backgrounds and relationships. The processing methods used for the production of spices are complex and individual. Consequently, the development of a reliable DNA-based method for spice analysis is a challenging intention. However, once established, this method will be easily adapted to less difficult food matrices. In the current study, several alternative methods for the isolation of DNA from spices have been developed and evaluated in detail with regard to (i) its purity (photometric), (ii) yield (fluorimetric methods), and (iii) its amplifiability (PCR). Whole genome amplification methods were used to preamplify isolates to improve the ratio between amplifiable DNA and inhibiting substances. Specific primer sets were designed, and the PCR conditions were optimized to detect 18 spices selectively. Assays of self-made spice mixtures were performed to proof the applicability of the developed methods.

  11. Viscosity measurement - probably a means for detecting radiation treatment of spices?

    Heide, L.; Albrich, S.; Boegl, K.W.

    1987-12-01

    The viscosity of 13 different spices and dried vegetables in total was measured. Optimal conditions were first determined for each product, i.e. concentration, pH-value, temperature, particle size and soaking time. For method evaluation, examinations were primarily performed to study the effect of storage, the reproducibility and the influence of the different varieties of the same spice. In supplement, for pepper, the viscosity was measured as a function of radiation dose. In summation, significant changes in the gel forming capability after irradiation could be observed after preliminary experiments in 8 dried spices (ginger, carrots, leek, cloves, pepper, celery, cinnamon and onions). With 3 spices (ginger, pepper and cinnamon) could the results from examining all different varieties of the same spice be substantiated. An additional influence of storage time on viscosity could not be proved during the investigative period of 8 months. Generally seen, there is no possibility of being able to identify an irradiated spice on the basis of viscosity measurements alone, since the difference between the varieties of one and the same spice is considerably great. However, radiation treatment can be reliably excluded with ginger, pepper and cinnamon, if the viscosities are high (10-20 Pa x s). (orig./MG) [de

    Dietary spices have been adopted in cooking since ancient times to enhance flavor and also as food preservatives and disease remedies. In China, the use of spices and other aromatic plants as food flavoring is an integral part of dietary behavior, but relatively little is known about their functions. Fatty acid synthase (FAS) has been recognized as a remedy target, and its inhibitors might be applied in disease treatment. The present work was designed to assess the inhibitory activities on FAS of spices extracts in Chinese menu. The in vitro inhibitory activities on FAS of 22 extracts of spices were assessed by spectrophotometrically monitoring oxidation of NADPH at 340 nm. Results showed that 20 spices extracts (90.9 %) exhibited inhibitory activities on FAS, with half inhibition concentration (IC(50)) values ranging from 1.72 to 810.7 μg/ml. Among them, seven spices showed strong inhibitory effect with IC(50) values lower than 10 μg/ml. These findings suggest that a large proportion of the dietary spices studied possess promising inhibitory activities on FAS, and subsequently might be applied in the treatment of obesity and obesity-related human diseases.

    Bioactive components of many foods added during cooking have potential antioxidant, anti-inflammatory, antimicrobial, antibacterial and chemopreventive properties. However, epidemiologic studies generally do not collect detailed information on these items which include spices, chilies, coconuts, garlic, onions, and oils. Since India has some of the highest spice consumption in the world, we developed a computer-based food preparer questionnaire to estimate per capita consumption of 19 spices, chilies, coconuts, garlic, onions, and 13 cooking oils among 3,625 participants in the India Health Study, a multicenter pilot study in three regions of India. We observed notable regional differences in consumption of spices, chilies, coconut, garlic, and onions. In Trivandrum, over 95 percent of the participants consumed 12 different spices, while in New Delhi and Mumbai, 95 percent of participants consumed only four and five spices, respectively. Cooking oil use also varied, as ghee was most common in New Delhi (96.8%) followed by mustard seed oil (78.0%), while in Trivandrum the primary oil was coconut (88.5%) and in Mumbai it was peanut (68.5%). There was some variation in consumption by education, income, and religion. Using a novel method for assessing food items primarily added during cooking, we successfully estimated per capita consumption within an epidemiologic study. Based on basic science research and suggestive ecologic level data on cancer incidence and spice consumption, improving epidemiologic assessment of these potentially chemopreventive food items may enhance our understanding of diet and cancer risk.

  14. Assessment of the microbiological safety of dried spices and herbs commercialized in Spain.

    Sospedra, Isabel; Soriano, Jose M; Mañes, Jordi

    2010-12-01

    Spices and herbs are natural products or their blends that must be free of extraneous matter content. Conventional production of these products implicates a number of hygienic problems so spices and herbs may be exposed to a wide range of microbial contamination during pre- and post-harvest and they can present high microbial counts. In this study, we have analyzed the microbial quality of 53 samples of spices and dry herbs collected from Spanish markets detecting a contamination of samples of spices with mesophilic aerobic counts (10%) and Enterobacteriaceae (20%). The analysis from herbs showed that the percentage of contamination was 26% in both microbiological values. Pathogenic microorganisms like Staphylococcus aureus, Yersinia intermedia, Shigella spp., Enterobacter spp., Acinetobacter calcoaceticus and Hafni alvei were also isolated from spices and herbs. These unsatisfactory results showed a poor microbiological quality. Spices and dry herbs are used as ingredients in a variety of products prepared in different ways, this fact suggests the need to provide a control system to improve the quality of herbs and spices.

  15. Effect of gamma irradiation on essential oils and lipids in spices

    Kaneko, Nobutada; Ito, Hitoshi; Ishigaki, Isao

    1991-01-01

    Seven kinds of spices were irradiated with gamma-rays at the dose of 5 to 80 kGy. Studies of radiation effect on lipids in each spice were carried out by measuring peroxide value (POV), iodine value (IV), acid value (AV) and analysis of gas-chromatography (GC). POV in each spice was gradually increased with increasing absorbed doses. The increase of POV in nutmeg was higher than those of other spices, and it was suggested that those increase of POV values were related to lipid contents in spices. A little increase of IV and AV were also observed as same amount of POV by the irradiation up to 80 kGy. From the GC analysis of lipids in each spice, components were not changed even irradiated up to 50 kGy of gamma-rays. Radiation effect on components of essential oils in each spice were also analyzed by headspace-GC (HS-GC), and any degradation of components were not observed up to 50 kGy of irradiation even analyzed by GC after separation to hydrocarbon and oxygen compounds. On the contrary, essential oils of cloves sterilized by heat treatment were apparently decreased as compared with irradiated and non-irradiated cloves. (author)

    Garvey, Thomas D; Lincoln, Patrick; Pedersen, Charles John; Martin, David; Johnson, Mark

    2003-01-01

    The goal of the BioSPICE program is to create a framework that provides biologists access to the most current computational tools. At the program midpoint, the BioSPICE member community has produced a software system that comprises contributions from approximately 20 participating laboratories integrated under the BioSPICE Dashboard and a methodology for continued software integration. These contributed software modules are the BioSPICE Dashboard, a graphical environment that combines Open Agent Architecture and NetBeans software technologies in a coherent, biologist-friendly user interface. The current Dashboard permits data sources, models, simulation engines, and output displays provided by different investigators and running on different machines to work together across a distributed, heterogeneous network. Among several other features, the Dashboard enables users to create graphical workflows by configuring and connecting available BioSPICE components. Anticipated future enhancements to BioSPICE include a notebook capability that will permit researchers to browse and compile data to support model building, a biological model repository, and tools to support the development, control, and data reduction of wet-lab experiments. In addition to the BioSPICE software products, a project website supports information exchange and community building.

    To determine whether an experiential nutrition education intervention focusing on spices and herbs ("Spice MyPlate") is feasible and improves diet quality and healthy eating attitudes among an urban and predominantly African-American sample of adolescents more than standard nutrition education alone. A nonrandomized controlled trial compared standard nutrition education in U.S. Department of Agriculture MyPlate guidelines (control group) with standard nutrition education plus adjuvant Spice MyPlate curriculum (intervention group). Data were collected at baseline and after 3, 6, and 10 weeks. Study setting was two public high schools in Baltimore, Maryland. A total of 110 students in grades 9 to 12 participated. The 6-week school-based intervention conducted during health class focused on cooking using spices and herbs to eat healthier diets according to MyPlate. Dietary intake reported on 3-day food records and healthy eating attitudes questionnaires was analyzed. Differences in diet quality and healthy eating attitudes between study groups were estimated by t-tests, Wilcoxon-Mann-Whitney tests, and covariate-adjusted regression models. Spice MyPlate was feasible and there were modest but significant improvements (p ≤ .05) in the Spice MyPlate group compared with control in whole grains (31.2 g/wk) and protein foods (13.2 ounces per week) intake, and attitudes toward eating vegetables, whole grains, lean protein, and low-fat dairy. Although randomized trials are needed, experiential nutrition education focusing on spices and herbs may help urban and predominantly African-American adolescent populations eat healthier diets. © The Author(s) 2016.

  18. Thermoluminescence analysis to detect irradiated spices, herbs and spice-and-herb mixtures - an intercomparison study. A report in English and German

    1993-01-01

    This report describes in detail an inter-laboratory test to detect the irradiation of spices, herbs and spice-and-herb mixtures in the dose range used for reduction of the number of contaminating microorganisms. Approx. 3 months and 9 months after irradiation the 14 participating laboratories determined the thermoluminescence (TL) of mineral contaminations that were isolated from coded samples. 18 different products (six spices, six herbs and six spice-and-herb mixtures) were examined. By whole sample analysis results were obtained in the inter-laboratory test which are typical for this method: Only one non-irradiated sample was classified as irradiated. By contrast, from some spice or herb products (5) all irradiated samples were correctly identified. From other products (3) some irradiated samples could not be identified as irradiated. From the rest of products (4) the majority of the irradiated samples was not identified as irradiated. Therefore, it is not possible to state definitively whether the whole sample method can be recommended as a screening technique. The decision rests with the user. However, data analysis of whole sample measurements revealed that the TL intensities of non-irradiated samples were within the same order of magnitude. Thus, there is no further need for establishing product-specific threshold values. The results make it clear that irradiation of spices, herbs and spice-and-herb mixtures with commercially used doses can be clearly detected by determination of TL signals of contaminating minerals throughout the entire period in which the products are normally stored and that the methods described are suitable for routine analysis in food inspection laboratories.

  19. Enhancing consumer liking of low salt tomato soup over repeated exposure by herb and spice seasonings.

    Ghawi, Sameer Khalil; Rowland, Ian; Methven, Lisa

    2014-10-01

    There is strong evidence for the link between high dietary sodium and increased risk of cardiovascular disease which drives the need to reduce salt content in foods. In this study, herb and spice blends were used to enhance consumer acceptability of a low salt tomato soup (0.26% w/w). Subjects (n = 148) scored their liking of tomato soup samples over 5 consecutive days. The first and last days were pre-and post-exposure visits where all participants rated three tomato soup samples; standard, low salt and low salt with added herbs and spices. The middle 3 days were the repeated exposure phase where participants were divided into three balanced groups; consuming the standard soup, the low salt soup, or the low salt soup with added herbs and spices. Reducing salt in the tomato soup led to a significant decline in consumer acceptability, and incorporating herbs and spices did not lead to an immediate enhancement in liking. However, inclusion of herbs and spices enhanced the perception of the salty taste of the low salt soup to the same level as the standard. Repeated exposure to the herbs and spice-modified soup led to a significant increase in the overall liking and liking of flavour, texture and aftertaste of the soup, whereas no changes in liking were observed for the standard and low salt tomato soups over repeated exposure. Moreover, a positive trend in increasing the post-exposure liking of the herbs and spices soup was observed. The findings suggest that the use of herbs and spices is a useful approach to reduce salt content in foods; however, herbs and spices should be chosen carefully to complement the food as large contrasts in flavour can polarise consumer liking.

  1. Historical aspects of Mexican psychiatry.

    Bayardo, Sergio Javier Villaseñor

    2016-04-01

    Mexican psychiatry initiated since pre-Hispanic times. Historically, treatments were a mixture of magic, science and religion. Ancient Nahuas had their own medical concepts with a holistic view of medicine, considering men and cosmos as a whole. The first psychiatric hospital appeared in 1566 and a more modern psychiatric asylum emerged until 1910. International exchanges of theoretical approaches started in the National University with the visit of Pierre Janet. There were other important figures that influenced Mexican psychiatry, such as Erich Fromm, Henri Ey, Jean Garrabé and Yves Thoret. Regarding Mexican psychiatrists, some of the most important contributors to Mexican psychiatry were José Luis Patiño Rojas, Manuel Guevara Oropeza and Ramón de la Fuente Muñiz. This article includes excerpts from "Clinical Psychiatry", a book by Patiño Rojas where he tries to understand and describe the inner world experienced by patients with schizophrenia; also, the thesis conducted by Guevara Oropeza ("Psychoanalisis"), which is a critical comparison between the theories of Janet and Freud. Finally, we include "The study of consciousness: current status" by Ramón de la Fuente, which leads us through the initial investigations concerning consciousness, its evolution, and the contributions made by psychology, philosophy and neurobiology.

    2014-06-01

    Full Text Available One among several equally important subsystems of a standalone photovoltaic (PV system is the circuit for maximum power point tracking (MPPT. There are several algorithms that may be used for it. In this paper we choose such an algorithm based on the maximum simplicity criteria. Then we make some small modifications to it in order to make it more robust. We synthesize a circuit built out of elements from the list of elements recognized by SPICE. The inputs are the voltage and the current at the PV panel to DC-DC converter interface. Its task is to generate a pulse width modulated pulse train whose duty ratio is defined to keep the input impedance of the DC-DC converter at the optimal value.

  10. Essential and trace elements in differential pulses, spices and vegetables

    Chowdhury, M.Z.A.

    2004-01-01

    The amounts of bio-chemically important elements for human bodies such as Na, K, Ca, P, Mg, Fe and Cu in some widely used pulses and spices in Chittagong were determined by using flame photometry and UV-Visible spectrophotometry. Similarly, the amounts of Mg, Fe and Cu in some leafy and non-leafy vegetable in Chittagong were determined by the UV-Visible spectrophotometric method. The essential elements such as Na, K, Ca and P were found in mg/kg levels. The amounts of trace metal such as Mg, Fe and Cu in pulses and species were just within the range of human necessity. However, the amounts of Mg, Fe and Cu in leafy and non-leafy vegetables were so negligible that they can not be considered as adequate for health, except their food-values constituted by the higher contents of starch.

Se recomienda enfatizar el abordaje de las variables que resultaron relevantes en la prevención de la recaída.

  12. The effect of irradiation, packaging and storage on the quality of spices

    Langerak, D.I.; Stegeman, H.

    1983-01-01

    Spices are contaminated by nature with micro organisms. The processing industry, however, requires 'clean' spices. The most applied technique has been fumigation with ethylene oxide. However, fumigation causes a number of difficulties; viz. the presence of residues and the possible forming of toxic compounds like ethylene chlorohydrine. The latest method is the decontamination by means of ionizing rays. Research on the effect of irradiation and packaging on the different quality aspects of spices proves that an irradiation dose of 3-8 kGy produces the same or better results with regard to decontamination effect as a fumigation treatment does. The applied dose has no adverse effect on the sensoric and chemical properties of the product. With respect to the wholesomeness the irradiation process can be applied safely. Furthermore, this process offers the possibility to choose an optimal packaging for spices, thus preventing quality deterioration. (orig.)

  14. Plant foods in the management of diabetes mellitus: spices as beneficial antidiabetic food adjuncts.

    Srinivasan, K

    2005-09-01

    Diet has been recognized as a corner stone in the management of diabetes mellitus. Spices are the common dietary adjuncts that contribute to the taste and flavour of foods. Besides, spices are also known to exert several beneficial physiological effects including the antidiabetic influence. This review considers all the available information from animal experimentation as well as clinical trials where spices, their extracts or their active principles were examined for treatment of diabetes. Among the spices, fenugreek seeds (Trigonella foenumgraecum), garlic (Allium sativum), onion (Allium cepa), and turmeric (Curcuma longa) have been experimentally documented to possess antidiabetic potential. In a limited number of studies, cumin seeds (Cuminum cyminum), ginger (Zingiber officinale), mustard (Brassica nigra), curry leaves (Murraya koenigii) and coriander (Coriandrum sativum) have been reported to be hypoglycaemic.

  15. Detection of irradiated spices using photo-stimulated luminescence technique (PSL)

    2014-09-03

    Photo-stimulated luminescence (PSL) technique was applied to detect irradiated black pepper (Piper nigrum), cinnamon (Cinnamomum verum) and turmeric (Curcuma longa) after dark storage for 1 day, 3 and 6 months. Using screening and calibrated PSL, all samples were correctly discriminated between non-irradiated and spices irradiated with doses 1, 5 and 10 kGy. The PSL photon counts (PCs) of irradiated spices increased with increasing dose, with turmeric showing highest sensitivity index to irradiation compared to black pepper and cinnamon. The differences in response are possibly attributed to the varying quantity and quality of silicate minerals present in each spice sample. PSL signals of all irradiated samples reduced after 3 and 6 months storage. The results of this study provide a useful database on the applicability of PSL technique for the detection of Malaysian irradiated spices.

  16. Monitoring of lead levels in spices and food colors using atomic absorption spectroscopy

    Rahman, S.; Khalid, N.; Ahmad, S.

    2001-01-01

    The concentration of lead has been monitored in various commercial brands of spices and food colours using atomic absorption spectrometry after digestion in a mixture of nitric acid and perchloric acid. The reliability of the procedure used was checked by analyzing the standard reference materials namely wheat flour (NBS-1567) and rice flour (NBS-1568), for their lead contents. The determined concentration of lead ranged from 5.60 to 10.12 mg g-1 in food spices and from 1.62 to 1.81 mg g-1 in food colours. The study revealed that the piper nigrum contains higher lead contents as compared to capsicum. The effect of processing/milling on the concentration of lead in spices was also studied and discussed. The daily intake of lead by adults through spices and food colours was estimated and was found to be within the recommended WHO tolerance levels. (author)

  20. Uranium isotopes distinguish two geochemically distinct stages during the later Cambrian SPICE event

    Dahl, Tais Wittchen; Boyle, Richard A.; Canfield, Donald E.

    2014-01-01

    . Here we report high-precision uranium isotopic data in marine carbonates deposited during the Late Cambrian 'SPICE' event, at ca. 499 Ma, documenting a well-defined -0.18‰ negative δ238U excursion that occurs at the onset of the SPICE event's positive δ13C and δ34S excursions, but peaks (and tails off......) before them. Dynamic modelling shows that the different response of the U reservoir cannot be attributed solely to differences in residence times or reservoir sizes - suggesting that two chemically distinct ocean states occurred within the SPICE event. The first ocean stage involved a global expansion...... depletion in the oceans (Gill et al., 2011). We discuss scenarios for how an interval of elevated pyrite and organic carbon burial could have been sustained without widespread euxinia in the water column (both non-sulfidic anoxia and/or a more oxygenated ocean state are possibilities). Either way, the SPICE...

    Spices were analyzed by ICP-MS for determination of the ultra-micro trace elements in the human adult, Bi, Cd, Co, Ni, Pd, Pt, Se, Sn, Te, Tl, to complement previous results obtained by INAA and by EDXRF. The spices, originating from Sri Lanka, were curry, chilli powder and turmeric powders, coriander, cinnamon, black pepper, fennel, rampeh and curry leaves, and cumin. The analytical procedure was validated by analyzing the certified reference materials NIST SRM 1572 Citrus Leaves and NIST SRM 1573 Tomato Leaves. The results indicate that spices may contribute well to the daily optimal uptake of nutrients of a human adult. The adequacy of spices as a reference material with certified ultra micro trace elements is suggested. (author)

    Food commonly is associated with emotion. The study was designed to determine if a spice blend (cinnamon, ginger, nutmeg, and cloves) high in antioxidants can evoke changes in consumer emotions. This was an exploratory study to determine the effects of these four spices on emotions. Three extruded, dry snack products containing 0, 4, or a 5% spice blend were tested. One day of hedonic and just-about-right evaluations (n = 100), followed by three days of emotion testing were conducted. A human clinical trial (n = 10), using the control and the 4% samples, measured total antioxidant capacity and blood glucose levels. The emotion “Satisfied” increased significantly in the 5% blend, showing an effect of a higher spice content. The 4% blend was significantly higher in total antioxidant capacity than the baseline, but blood glucose levels were not significantly different. PMID:28820459

    2014-09-01

    Photo-stimulated luminescence (PSL) technique was applied to detect irradiated black pepper (Piper nigrum), cinnamon (Cinnamomum verum) and turmeric (Curcuma longa) after dark storage for 1 day, 3 and 6 months. Using screening and calibrated PSL, all samples were correctly discriminated between non-irradiated and spices irradiated with doses 1, 5 and 10 kGy. The PSL photon counts (PCs) of irradiated spices increased with increasing dose, with turmeric showing highest sensitivity index to irradiation compared to black pepper and cinnamon. The differences in response are possibly attributed to the varying quantity and quality of silicate minerals present in each spice sample. PSL signals of all irradiated samples reduced after 3 and 6 months storage. The results of this study provide a useful database on the applicability of PSL technique for the detection of Malaysian irradiated spices.

  6. Flash spice as a tool for analysing the impact of radiation

    Charlot, J.J.; Alali, O.

    1997-01-01

    The Spice simulator must be enhanced with behavioural capabilities for analysing the effects of hostile environments (e.g. radiation exposure) on components, circuits and systems. One solution for achieving this uses the in-house BVHDLA translator to convert from models in analog VHDL Language to models that will be recognized by Spice. This article gives an example combined with self-heating in a MOS transistor. (authors)

    2003-01-01

    The changes in spice paprika powder induced by ionizing radiation, saturated steam (SS) and their combination were studied as a function of the absorbed radiation dose and the storage time. The SS treatment lead to a decrease in color content (lightening) after 12 weeks of storage, together with the persistence of free radicals and viscosity changes for a longer period. The results suggest that ionizing radiation is a more advantageous method as concerns preservation of the quality of spice paprika

It may be the risk for human health. The prognosis has been shown, the microbiological decontamination of spices by irradiation may be one of the elements of new system - Hazard Analysis Critical Control Point (HACCP). (author)

  9. Scent and synaesthesia: The medical use of spice bags in early China.

    Lu, Di; Lo, Vivienne

    2015-06-05

    The history of Chinese spices has received increasing attention in recent years, but little research been carried out on where they fit on the food-medicine continuum for early China, during the formation of the classical medical system. This paper describes how the synaesthetic qualities of spices attracted a particular analysis in that emerging system which serves to mark them as different to other medical materials and foodstuffs. We aim to clarify the special role created for spices to accommodate their boundary-crossing synaesthetic action on the body. This paper analyses the contents of several spice bags excavated in 1972 from a tomb that was closed in the second century BCE. It uses archaeological reports of material culture together with the early Chinese textual record, extant in both manuscripts and received texts, to bring out the role of spices in ritual, food and medicine. Noting that the flavours and aromas of early China were assigned physiological potency in the first centuries BCE, we argue that by medieval times the unique synaesthetic role that spices played in mediating the senses was systematically medicalised. While being deployed for the purpose of curing disease in medicine, they also remained within the realm of everyday healthcare, and religious practice, deployed both as aromatics to perfume the environment, attracting benign spirits, but also to ward off the agents of disease, as well as for enhancing health through their use in cookery. While foodstuffs entered the digestive system spices were all considered 'pungent' in the emerging clasical medical system. They acted on the body through the nose and lungs, making them neither food nor drug. This implicit categorisation medicalised spices which, like music, could affect the passions and lighten the spirit, codifying observations about the impact on the body of the ritual environment.

  10. Cold adaptive thermogenesis following consumption of certain pungent spice principles: A validation study.

    Pandit, Chaitanya; Anilakumar, K R

    Identifying a means to activate or potentiate thermogenic mechanisms through ingestion of dietary compounds have important implications in cold endurance and survival. Although many reports discuss the thermogenic potential of spices, it is surprising that none of the studies verify whether consumption of spices can improve cold endurance. In this study, we have attempted to evaluate if ingestion of certain spices can activate heat-generating mechanisms in the body such that a fall in. core body temperature (CBT) can be delayed or prevented when faced with a cold challenge. Ten commonly used spices in the Indian cuisine were chosen and 70% ethanol extract of the spices were fed orally to male Wistar rats at a dose of 250mg/kg for a period of 7 days. A change in CBT during cold exposure was recorded before and after treatment. At the end of the experiment, plasma norepinephrine and serum free fatty acid levels were estimated. We observed that among the ten spices, treatment with cinnamon and pepper extracts showed significant improvement in comparison to the control group. Based on evidence in literature and the HPLC-MS analysis from our lab, we hypothesized that the effects of the pepper and cinnamon extracts might be due to their piperine and cinnamaldehyde content respectively. However, no improved endurance was observed when they were administered alone. Poor endurance following depletion of endogenous norepinephrine levels using reserpine indicated its involvement in mediating the heat generating processes. However, it is noteworthy that green tea and spice treated animals exhibited a fall in CBT which was lower than their initial fall. In conclusion, our findings provide experimental evidence that ingestion of spices, viz., pepper and cinnamon, might elicit thermogenic responses such that hypothermia can be delayed or prevented upon cold exposure.

    2015-08-01

    The cultivation of spices and herbs in parts of the world characterized by warm climate and high humidity provides excellent conditions for the development of microorganisms, including the undesirable ones. The aim of this study was to determine the microbiological quality of spices and herbs available on the Polish market, considering the occurrence of Cronobacter species bacteria. Analyses covered 60 samples of commercial spices and herbs, including 38 samples of dried herbs (basil, bay leaves, thyme, oregano, tarragon, marjoram, dill, parsley, rosemary, lovage) and 16 samples of seasoning blends as well as 6 samples of spices seeds and fruits (pimento, black pepper, coriander). All samples were tested for the total count of aerobic mesophilic bacteria (TAMB) and for the presence of Cronobacter spp. In most of the samples of spices and herbs (60.0%), the TAMB did not exceed 10(4) CFU/g, and the level regarded as unacceptable (>10(6) CFU/g) was not identified in any of the samples. The presence of Cronobacter spp. was demonstrated in 10 (16.7%) samples of the analyzed products, however these were mainly samples of herbs (basil, tarragon, parsley) and one sample of a seasoning blend (Provence herbs). The highest microbiological contamination (TAMB) was found in samples of herbs (oregano, tarragon, basil) and in ready seasoning blends, in 21.1% and 25.0% of which the total count of aerobic mesophiles was in the range of 10(5)-10(6) CFU/g. In all samples of spices seeds and fruits (coriander, black pepper and pimento), the total count of aerobic bacteria reached spices and herbs available on the Polish market. The study demonstrated also that dried spices and herbs may be carriers of Cronobacter species bacteria, though their presence in not often detected in products of this type.

    1982-01-01

    Results of separation and determination of zinc present in four spices, viz. Coriander, King's cumin, Fennel and Fenugreek seeds by IDA are presented. It is observed that zinc could be estimated by substoichiometric extraction as dithiozonate followed by IDA, in spices. The substoichiometric extraction results at lower concentrations of zinc also, but better results are obtained by increasing the concentration of zinc. The substoichiometric IDA agrees fairly with the conventional chemical analysis.

    For the identification of irradiated food, current analysis methods have limitations regarding presence and stability of radiation-induced markers. In this study, different spice blends with small quantity of different irradiated (0, 1 and 10 kGy) spice powders, such as red pepper, garlic or ginger, were investigated using PSL and TL techniques. In PSL-based screening analysis, the spice blends containing 10% of irradiated materials (1 or 10 kGy) were determined as intermediate or positive. In TL results, the blends containing 1% of 1 or 10 kGy-irradiated spices showed the typical TL glow curves that could be interpreted as positive. The blends with irradiated garlic powder provided more good results where identification was possible at 0.5% mixing of irradiated sample. However, the TL ratios of all spice blends were <0.1 and only TL glow curve shape and intensity may be used to discriminate the samples having irradiated component. - Highlights: ► Sample blends with small quantities of irradiated spices were evaluated. ► The PSL was inappropriate to detect irradiated ingredient in small quantity. ► TL glow curve shape and intensity could be used as conclusive evidence of irradiation. ► TL ratios of all irradiated and nonirradiated samples were <0.1.

    The shelf-life of packed minced meat has been increased at least threefold at 4{sup 0}C by applying a 2 kGy dose. Results have been confirmed by detailed quantitative microbiological examinations. Sensory evaluations show no significant difference between the unirradiated and irradiated samples. The optimal average dose was 4 kGy for packed-frozen chicken. The number of mesophilic aerobic microbes was reduced by 2, that of psychrotolerant by 2-3 and that of Enterobacteriaceae by 3-4 orders of magnitude by 4 kGy. S. aureus and Salmonella could not be detected in the irradiated samples. in 1984-1985 5100 kg irradiated chickens were marketed labelled as radiation treated. Irradiated spices (5 kGy) were used in the production of sausages (heat-treated and non-heat-treated) under industrial conditions. The microbiological contamination of irradiated spices was lower than that of ethylene oxide treated ones. The cell count in products made with irradiated spices was lower than in those made with unirradiated spices. The sausages proved to be of very good quality. In accordance with the permission, products were marketed and because of the low ratio of spices there was no need to declare them as using irradiated spices. (author).

    In the recent years, there has been a growing interest in monitoring heavy metal contamination of spices/herbs. Spices and herbs are sources of many bioactive compounds that can improve the tastes of food as well as influence digestion and metabolism processes. In the present study, the levels of some essential and toxic elements such as iron (Fe), zinc (Zn), copper (Cu), chromium (Cr), manganese (Mn), cobalt (Co), nickel (Ni), lead (Pb), and cadmium (Cd), present in common spices/herbs that were purchased from the local market in Saudi Arabia, were analyzed by atomic absorption spectroscopy after digestion with nitric acid/hydrogen peroxide mixture. Samples from the following spices/herbs were used: turmeric, cloves, black pepper, red pepper, cumin, legume, cinnamon, abazir, white pepper, ginger, and coriander. The concentration ranges for the studied elements were found as 48.8-231, 4.7-19.4, 2.5-10.5, below detection level (BDL)-1.0, 8.8-490, 1.0-2.6, and BDL-3.7 µg g(-1) for Fe, Zn, Cu, Cr, Mn, Ni, and Pb, respectively, while Cd and Co levels were below the detection limit. Consumers of these spices/herbs would not be exposed to any risk associated with the daily intake of 10 g of spices per day as far as metals Fe, Zn, Cu, Cr, Mn, Ni, and Pb are concerned. © The Author(s) 2013.

    Spices have enjoyed a long history and a worldwide application. Of particular interest is the pharmaceutical value of spices in addition to its basic seasoning function in cooking. Concretely, equipped with complex chemical compositions, spices are of significant importance in pharmacologic actions, like antioxidant, antibacterial, antitumor, as well as therapeutical effects in gastrointestinal disorders and cardiovascular disease. Although increasing evidences in support of its distinct role in the medical field has recently reported, little information is available for substantive, thorough and sophisticated researches on its chemical constituents and pharmacological activities, especially mechanism of these actions. Therefore, in popular wave of studies directed at a single spice, this review presents systematic studies on the chemical constituents and pharmacological activities associated with common used spices, together with current typical individual studies on functional mechanism, in order to pave the way for the exploitation and development of new medicines derived from the chemical compounds of spice (such as, piperine, curcumin, geniposide, cinnamaldehyde, cinnamic acid, linalool, estragole, perillaldehyde, syringic acid, crocin).

    Tosun, Halil; Arslan, Recep

    2013-01-01

    Organically produced spices and herbs were analyzed for determination of aflatoxin B1 (AFB1) by ELISA using immunoaffinity column. For this purpose 93 organic spices and 37 organic herbs were randomly selected from organic markets and organic shops in Turkey. AFB1 was detected in 58 organic spice and 32 organic herb samples. Among organic spice samples, the maximum value was detected in cinnamon sample (53 μg/kg). AFB1 was not detected in thyme samples. AFB1 levels of 41 organic spice samples were above the EU regulatory limit (5 μg/kg). Among organic herb samples the highest concentration of AFB1 (52.5 μg/kg) was detected in a rosehip sample. AFB1 levels of 21 organic herb samples were above the regulatory limits of the European Union. These results showed that more stringent measures must be taken for the prevention of mold contamination in the production of organic spices and herbs. PMID:23766719

    2018-06-01

    A simple and solvent-free method was developed for the authentication of commercial spices. The similarities between gas chromatographic fingerprints were measured using similarity indices and multivariate data analyses, as morphological differentiation between dried powders and small spice particles was challenging. The volatile compounds present in 11 spices (i.e. allspice, anise, black pepper, caraway, clove, coriander, cumin, dill, fennel, star anise, and white pepper) were extracted by headspace solid-phase microextraction, and analysed by gas chromatography-mass spectrometry. The largest 10 peaks were selected from each total ion chromatogram, and a total of 65 volatiles were tentatively identified. The similarity indices (i.e. the congruence coefficients) were calculated using the data matrices of the identified compound relative peak areas to differentiate between two sets of fingerprints. Where pairs of similar fingerprints produced high congruence coefficients (>0.80), distinctive volatile markers were employed to distinguish between these samples. In addition, hierarchical cluster analysis and principal component analysis were performed to visualise the similarity among fingerprints, and the analysed spices were grouped and characterised according to their distinctive major components. This method is suitable for screening unknown spices, and can therefore be employed to evaluate the quality and authenticity of various spices. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

  2. Effect of the dose of irradiation on the conservation of the spice

    2008-01-01

    The effect of the gamma rays treatment emitted by a source of cobalt 60 in dose of 0, 3, 6 and 10 kGy on the microbiological and psycho-chemical properties of three samples of spice (hot pepper, fennel and coriander) have been studied. This study allowed us to measure the effect of these doses of irradiation on the lengthening of the lengthen conservation during storage of eight weeks to ambient temperature. The results show that the irradiation is very effective from a microbiological stand point. In fact, starting from 10 kGy the spices was not contaminated any more. The irradiation until a dose of dose 10 kGy has not generated any significant modifications, mainly in the physico-chemical parameters of the spices. But high diminishing has ac cured in water potency. Regarding colour variation, the irradiation has permitted the creation of a brighter colour for the three spices treated. A long the follow up we have an important multiplication in all bacteria existent in the three spices. Hew ever for the spices treated in 10 kGy we did not get any recontamination. (Author)

    Coventry, M J; Hickey, M W

    1993-01-01

    Three species, two proprietary spice blends and six starter preparations used in commercial salami manufacture were analysed for manganese and magnesium content. A mettwurst spices blend showed the highest levels of manganese (0·77 ppm expressed as effective product level assuming a 1% spice content) while mild and hot paprika and milano blend contained levels of manganese 1 4 - 1 3 lower. Magnesium levels for spices ranged from 3·14 to 25·81 ppm. Only two of the six meat starter cultures showed high levels of manganese (7·77 and 16·12 ppm as effective product level based on inoculation rate) while magnesium levels for all starter cultures did not exceed 0·37 ppm. The pH of salami products made with starter cultures containing no added manganese lagged behind that of products made with added mangenese (5 ppm) by 0·2 pH units at 48 h. The effect of manganese ions on the fermentation rate of starter bacteria was studied further in a salami model system, in the absence and presence of added spices. The mettwurst blend produced greatest stimulation and the milano the least. A level of 1·2 ppm of added manganese was sufficient to achieve an optimal (spices tested in the salami model system.

    Full Text Available Bee honey is nutritious and has numerous health benefits, but its taste is for many people too bland. Honey with addition of spices could be important to the food industry as a functional product with positive health image and interesting taste. Such product would definitely meet health-driven consumers’ expectations. Therefore, the aim of this study was to evaluate the effect of addition of selected spices on sensory, antimicrobial, and antioxidant properties of honey. Results showed that the addition of spices significantly affected the taste and the smell of honey (p<0,05 and that honey with the cinnamon was the most desired and easily accepted product by the consumers. The addition of spices had no significant effect on texture and appearance. All tested samples showed the ability to inhibit the growth of bacteria and, contrary to the assumptions, the addition of spices did not cause an increase of antimicrobial activity. The results also showed that the kind and amount of added spice significantly affected the antioxidant activity: ability to scavenge free radicals and total phenolics content. The highest antioxidant activity revealed the honey with cinnamon and the lowest revealed the honey with cardamom addition.

    Full Text Available El objetivo fundamental de este artículo consiste en analizar y explicar, a través del libro XI de la novela apuleyana, aspectos significativos de los usos religiosos y de su comportamiento en el imaginario de una sociedad. En este sentido las religiones de misterios pueden llegar, en su complejidad y a través de sus diversas máscaras, a simbolizar la integración de las fuerzas del cosmos, presentando un sistema de representación y de integración global del mundo y de la sociedad. La universalidad de las mismas es el escenario en donde los fieles creen que conseguirán la igualdad prometida, aunque ficticia, ya que en realidad implica una sumisión y dependencia de las órdenes y dictados de los dioses, en nuestro caso de la diosa Isis, cuya supremacía y soteriología garantizará a los fieles la protección y salvación en esta vida y en el más allá. El análisis del léxico de dependencia, presente en todo el texto, desvela a nivel simbólico-religioso las relaciones sociales propias de la sociedad romana, reforzandorenovando, a través de los nuevos valores proporcionados por el isismo, el control ideológico sobre los creyentes-fieles, hasta el punto de interiorizar estas relaciones de dependencia y considerarlas como igualitarias en un horizonte de dominación-sumisión.

  8. New tariffs confuse Mexican market

    Coeyman, M.

    1992-01-01

    Indelpro - the Grupo Alfa/Himont joint venture 150,000-m.t./year polypropylene (PP) plant in Altamira, Mexico - has been working to find its place in the Mexican market since coming onstream in March. At the same time, that market has been complicated by the imposition of import and export tariffs by the U.S. Department of Commerce early this fall. Commerce's accession to a 10% ad valorem tax on US PP exports to Mexico surprised some industry observers. The tariff is scheduled to be phased out within 10 years and is partly countermanded by a 5% tariff over a five-year period on Mexican PP exports to the US. But some market analysts say the arrangement is baffling

  9. Intakes of culinary herbs and spices from a food frequency questionnaire evaluated against 28-days estimated records.

    2011-05-16

    Worldwide, herbs and spices are much used food flavourings. However, little data exist regarding actual dietary intake of culinary herbs and spices. We developed a food frequency questionnaire (FFQ) for the assessment of habitual diet the preceding year, with focus on phytochemical rich food, including herbs and spices. The aim of the present study was to evaluate the intakes of herbs and spices from the FFQ with estimates of intake from another dietary assessment method. Thus we compared the intake estimates from the FFQ with 28 days of estimated records of herb and spice consumption as a reference method. The evaluation study was conducted among 146 free living adults, who filled in the FFQ and 2-4 weeks later carried out 28 days recording of herb and spice consumption. The FFQ included a section with questions about 27 individual culinary herbs and spices, while the records were open ended records for recording of herbs and spice consumption exclusively. Our study showed that the FFQ obtained slightly higher estimates of total intake of herbs and spices than the total intake assessed by the Herbs and Spice Records (HSR). The correlation between the two assessment methods with regard to total intake was good (r = 0.5), and the cross-classification suggests that the FFQ may be used to classify subjects according to total herb and spice intake. For the 8 most frequently consumed individual herbs and spices, the FFQ obtained good estimates of median frequency of intake for 2 herbs/spices, while good estimates of portion sizes were obtained for 4 out of 8 herbs/spices. Our results suggested that the FFQ was able to give good estimates of frequency of intake and portion sizes on group level for several of the most frequently used herbs and spices. The FFQ was only able to fairly rank subjects according to frequency of intake of the 8 most frequently consumed herbs and spices. Other studies are warranted to further explore the intakes of culinary spices and herbs.

  18. Spore prevalence and toxigenicity of Bacillus cereus and Bacillus thuringiensis isolates from U.S. retail spices.

    Hariram, Upasana; Labbé, Ronald

    2015-03-01

    Recent incidents of foodborne illness associated with spices as the vehicle of transmission prompted this examination of U.S. retail spices with regard to Bacillus cereus. This study focused on the levels of aerobic-mesophilic spore-forming bacteria and B cereus spores associated with 247 retail spices purchased from five states in the United States. Samples contained a wide range of aerobic-mesophilic bacterial spore counts (spices had high levels of aerobic spores (> 10(7) CFU/g). Using a novel chromogenic agar, B. cereus and B. thuringiensis spores were isolated from 77 (31%) and 11 (4%) samples, respectively. Levels of B. cereus were spice isolates to form spores, produce diarrheal toxins, and grow at moderately abusive temperatures makes retail spices an important potential vehicle for foodborne illness caused by B. cereus strains, in particular those that produce diarrheal toxins.

    The Federal Law on Metrology and Normalization operative since July 16 1992, establishes that it corresponds to the dependencies of Federal Public Administration (APF), in its scope of competence, to constitute the National Consultative Committee of Normalization (CCNN) to issue the Mexican official norms (NOM) on products, systems, processes, methods, facilities, services or activities, as well as to certify, to verify and inspect its fulfillment. The NOMs are of obligatory application since their purpose is the establishment of the characteristics and/or specifications, criteria and procedures that allow to protect and to promote the improvement of the environment and ecosystems, as well as the preservation of the natural resources. The normalization for the power efficiency in the constructions represents an effort directed to the improvement of the thermal design of buildings and to the obtaining of its inhabitants' comfort with a smaller energy consumption. The heat gain by solar radiation is the source most important to control, a control obtained with a suitable design of the building covering. [Spanish] La Ley Federal sobre Metrologia y Normalizacion en vigor desde el 16 de julio de 1992, establece que corresponde a las dependencias de la Administracion Publica Federal (APF), en su ambito de competencia, constituir los Comite consultivo Nacional de Normalizacion (CCNN) para expedir las normas oficiales mexicanas (NOM) sobre productos, sistemas, procesos, metodos, instalaciones, servicios o actividades, asi como certificar, verificar e inspeccionar su cumplimiento. Las NOM son de aplicacion obligatoria porque tienen como finalidad establecer las caracteristicas y/o especificaciones, criterios y procedimientos que permitan proteger y promover el mejoramiento del ambiente y los ecosistemas, asi como la preservacion de los recursos naturales.

  20. Investigations on the detection of irradiated food by measuring the viscosity of suspended spices and dried vegetables

    Heide, L.; Nürnberger, E.; Bögl, K. W.

    Studies on the viscosity behavior were performed with 20 different spices or dried vegetables. In nine spices (cinnamon, ginger, mustard seed, celery, onions, shallots, lemon peel, black and white pepper) differences between unirradiated and irradiated samples were observed. Further lots were investigated to estimate the variations of viscosity depending on the origin of the samples. Additional storage experiments showed that measuring the viscosity may be a simple method to identify some radiation treated spices even after years.

  1. Data-driven analysis of biomedical literature suggests broad-spectrum benefits of culinary herbs and spices.

    Rakhi, N K; Tuwani, Rudraksh; Mukherjee, Jagriti; Bagler, Ganesh

    2018-01-01

    Spices and herbs are key dietary ingredients used across cultures worldwide. Beyond their use as flavoring and coloring agents, the popularity of these aromatic plant products in culinary preparations has been attributed to their antimicrobial properties. Last few decades have witnessed an exponential growth of biomedical literature investigating the impact of spices and herbs on health, presenting an opportunity to mine for patterns from empirical evidence. Systematic investigation of empirical evidence to enumerate the health consequences of culinary herbs and spices can provide valuable insights into their therapeutic utility. We implemented a text mining protocol to assess the health impact of spices by assimilating, both, their positive and negative effects. We conclude that spices show broad-spectrum benevolence across a range of disease categories in contrast to negative effects that are comparatively narrow-spectrum. We also implement a strategy for disease-specific culinary recommendations of spices based on their therapeutic tradeoff against adverse effects. Further by integrating spice-phytochemical-disease associations, we identify bioactive spice phytochemicals potentially involved in their therapeutic effects. Our study provides a systems perspective on health effects of culinary spices and herbs with applications for dietary recommendations as well as identification of phytochemicals potentially involved in underlying molecular mechanisms.

    The irradiation of foods is one of the common practices in several countries of the American and European continents. In spite of the widespread use of irradiation methods and technics of nutritious products, it doesn't exist a method of general use at the present time for the detection of previously submitted foods to irradiation with pasteurization ends or sterilization. In the present work the results are presented obtained in the detection of herbs and spices exposed to radiation in the range of 0.1 - 3 KGy, by means of the photostimulation with light of 470 nm. It was used for it a RIS0 model team TL/OSL-GIVE-15 conditioned with a β ray source, 90 Sr/ 90 Y and a source of light of 50 mW/cm2. samples of chili guajillo were studied, pepper, cumin, mint and camomile; achieving you to detect exhibitions of the order of 8.33x10 -4 KGy that which is indicative of the high sensitivity of the luminescence technique optically stimulated. The answer of the samples with regard to the radiation dose presents a range of lineality for low dose of the order of 0.5 KGy; and supralineal for further dose without to arrive to a saturation stage.

    2015-01-01

    The analysis of aflatoxins (B1, B2, G1 and G2) and ochratoxin A (OTA) was performed in processed spices marketed in Penang, Malaysia, using immunoaffinity columns and HPLC equipped with fluorescence detector (HPLC-FD). The processed powdered spices analysed include dried chilli, fennel, cumin, turmeric, black and white pepper, poppy seed, coriander, 'garam masala', and mixed spices for fish, meat and chicken curry. Two different studies were carried out. The limit of detection (LOD) was 0.01 ng g(-1) for each aflatoxin (AF) and 0.10 ng g(-1) for OTA (signal-to-noise ratio = 3:1). In the first study, 34 commercial processed spices analysed with a mean level, range and incidence of positive samples for total AF were 1.61 ng g(-1), 0.01-9.34 ng g(-1) and 85%, respectively, and for AFB1 were 1.38 ng g(-1), 0.01-7.68 ng g(-1) and 85%, respectively. The mean level, range and incidence of positive samples for OTA were 2.21 ng g(-1), 0.14-20.40 ng g(-1) and 79%, respectively. Natural co-occurrence of AF and OTA was found in 25 (74%) samples. In the second study of 24 commercial processed spices, the mean level, range and incidence of positive samples for total AF were 8.38 ng g(-1), 0.32-31.17 ng g(-1) and 88%, respectively, and for AFB1 were 7.31 ng g(-1), 0.32-28.43 ng g(-1) and 83%, respectively. Fifteen positive samples for total AF and two positive samples for OTA exceeded the permissible Malaysian limit of 5 ng g(-1). Contamination of both mycotoxins in spices may represent another route of exposure to consumers due to their frequent and prolonged consumption, as spices are common ingredients in popular dishes among Asian countries.

  9. Inhibitory activity of Asian spices on heterocyclic amines formation in cooked beef patties.

    Puangsombat, Kanithaporn; Jirapakkul, Wannee; Smith, J Scott

    2011-10-01

    Heterocyclic amines (HCAs) are mutagenic compounds formed when foods are cooked at high temperatures. Numerous reports have shown that natural antioxidants from spices, fruits, chocolate, and tea can inhibit formation. In this study, we evaluated HCA formation in the presence of 5 of Asian spices: galangal (Alpinia galangal), fingerroot (Boesenbergia pandurata), turmeric (Curcuma longa), cumin (Cuminum cyminum), and coriander seeds (Coriandrum sativum). HCA levels were compared to patties containing rosemary (Rosmarinus officinalis), of which the inhibitory effect is well documented. Inhibition of HCA formation by the spices was evaluated in beef patties cooked at 204 °C (400 °F) for 10 min. All spices were mixed into patties at 0.2% before cooking, and HCAs levels were measured in the final product. All patties, including the control, contained 2-amino-3,8-dimethylimidazo [4,5-f]quinoxaline (MeIQx) and 2-amino-1-methyl -6-phenylimidazo [4,5-b]pyridine (PhIP). The average HCA content of the control patties was 7 ng/g MeIQx and 6.53 ng/g PhIP. Turmeric (39.2% inhibition), fingerroot (33.5% inhibition), and galangal (18.4% inhibition) significantly decreased HCAs compared with the control. But, only turmeric and fingerroot were as effective as rosemary in preventing HCA formation. The HCA inhibition in patties containing spices was significantly correlated to the total phenolic content (R(2) = 0.80) and the scavenging activity (R(2) = 0.84) of the spices as measured by the 2,2-diphenyl-β-picrylhydrazyl assay. Results of this study suggest that addition of Asian spices can be an important factor in decreasing the levels of HCAs in fried beef patties. © 2011 Institute of Food Technologists®

    Full Text Available Se presenta la evolución de la protección social de la dependencia en España desde la década de los noventa hasta el momento actual y se plantean las consecuencias de la falta de acuerdo político respecto a las medidas a implementar. Se analizan los elementos en los que se basan las políticas de dependencia, resaltando sus aspectos positivos y negativos, así como las consecuencias para los ancianos y sus cuidadores informales. También se pone de manifiesto cómo, ante la posibilidad de quiebra del papel de la familia en el cuidado de los dependientes, se están implementando políticas que tienen como objetivo reforzar el rol cuidador de la familia y que se enmarcan dentro de la denominada "Conciliación de la Vida Familiar y Laboral". Estas políticas, más allá de sus contribuciones positivas, implican también importantes costes personales y de oportunidad para los cuidadores informales.

Ha sido utilizado, entre otras áreas, en el contexto de los problemas de ansiedad, observándose una relación no con el "rasgo", pero sí con el "estado" de ansiedad. Nosotros lo hemos utilizado con una muestra de 79 sujetos, junto con el ISRA, para veri¬ficar si la Dependencia de campo es un factor de vulnerabilidad para la ansiedad y, con 53 sujetos, para ver si tiene repercusión en el aprovechamiento terapéutico. Resultados: los Dependientes tienen unos niveles de ansiedad mayores (p=0,018. El tratamiento beneficia más a los Independientes, y lo hace en el sistema de respuesta cognitivo (p=0,047. Se aconseja atomizar el constructo en subprocesos que permitan una mejor identificación de los mecanismos implicados en la desventaja que presentan los Dependientes de campo ante los problemas de ansiedad.

  15. Comparison of the Effect of New Spice Freon Extracts Towards Ground Spices and Antioxidants for Improving the Quality of Bulgarian-Type Dry-Cured Sausage

    Balev Dessislav Kostadinov

    2017-03-01

    Full Text Available Ground spices are a source of hazards for dry-fermented meat products. Since dry-cured sausages are not subjected to heat treatment, there is a high risk of microbial cross-contamination and physical impurities. The aim of this study was to determine effects of the replacement of 3 g/kg of ground black pepper (Piper nigrum L., and cumin (Cuminum cyminum with their aliquots of new freon extracts, and compare them with the effect of 0.2 g/kg antioxidant addition (taxifolin extract from Siberian larch (Larix sibirica Ledeb, rosemary (Rosmarinus officinalis L. extract, and butylated hydroxytoluene on sensory properties, color stability, proximate composition, free amino nitrogen and pH of Bulgarian-type dry-cured „Sudjuk“ sausages. The replacement of natural ground spices with aliquots of their extracts improved sensory properties and stabilized the color characteristics of the final product during 30 days of storage at 0–4°C. The addition of 0.2 g/kg rosemary extract was as effective as the addition of freon extracts on the overall assessment to the 14th day of the experiment. It was determined that the addition of antioxidants or spice extracts had no significant effect on proximate composition, pH, and free amino nitrogen accumulation of the “Sudjuk”. The addition of 0.2 g/kg, taxifolin or rosemary extracts and butylated hydroxytoluene was not so efficient in improving the sensory properties and color stabilization in comparison to the new freon spice extracts. The examined spice extracts can be successfully used to improve the quality of “Sudjuk” sausages.

    Jimenez C, M.J.

    2005-01-01

    50% of the Mexican territory is formed by volcanic sequences of the Pliocene type, which appear extensively in the northwest states (Sonora, Sinaloa, Chihuahua, Durango) and west of Mexico (Jalisco and Nayarit), in central Mexico (Zacatecas, Guanajuato, San Luis Potosi, Queretaro, Hidalgo) and south of Mexico (Guerrero, Oaxaca); therefore, it is to be expected that in our country big locations of natural zeolites exist in its majority of the clinoptilolite type. The present study was focused toward the characterization of two Mexican natural zeolite rocks presumably of the clinoptilolite and filipsite types, one of them comes from the state of Chihuahua and the other of a trader company of non metallic minerals, due that these materials are not characterized, its are not known their properties completely and therefore, the uses that can be given to these materials. In this investigation work it was carried out the characterization of two Mexican zeolite rocks, one coming from the Arroyo zone, municipality of La Haciendita, in the state of Chihuahua; and the other one was bought to a trader company of non metallic minerals. The two zeolites so much in their natural form as conditioned with sodium; they were characterized by means of X-ray diffraction, scanning electron microscopy of high vacuum and elementary microanalysis (EDS), surface area analysis (BET), thermal gravimetric analysis. To differentiate the heulandite crystalline phase of the other clinoptilolite rock, its were carried out thermal treatments. The quantification of Al, Na, Ca, K, Mg, Fe was carried out in solution, by means of atomic absorption spectroscopy and the quantity of Si was determined by gravimetry. The zeolite rocks presented for the major part the crystalline heulandite and clinoptilolite phases for the most part, and it was found that the zeolite coming from the state of Chihuahua possesses a bigger content of heulandite and the denominated filipsite it is really a zeolite

  18. Effect of electron-beams irradiation for inactivation of microorganisms on spices

    Ito, Hitoshi; Islam, Md.S.

    1993-01-01

    Total aerobic bacteria in spices used in this study were determined to be 1x10 6 to 6x10 7 per gram. A study on the inactivation of microorganisms in spices showed that doses of 6 to 9 kGy of EB (electron-beams) or gamma irradiation were required to reduce the total aerobic bacteria tobelow 10 3 per gram. However, a little increase of resistance was observed on the inactivation of total aerobic bacteria in many spices in case of EB irradiation. These difference of radiation sensitivities between EB and gamma-rays was explained by dose rate effect on oxidation damage to microorganisms from the results of radiation sensitivities of Bacillus pumilus and B. megaterium spores at dry conditions. On the other hand, these high dose rate of EB irradiation suppressed the increase of peroxide values in spices at high dose irradiation up to 80 kGy. Components of essential oils in spices were not changed even irradiated up to 50 kGy with EB and gamma-rays. (author)

  19. Evaluation of identification methods of irradiated spices and dehydrated vegetables in Brazil

    Bernardes, D.M.L.; Del Mastro, N.L.

    1998-01-01

    Complete text of publication follows. This paper deals with the use of analytical methods to determine whether imported or for export Brazilian spices and dehydrated vegetables were irradiated. Viscosimetry, thermoluminescence (TL) and electron spin resonance (ESR) were used for the identification of some irradiated products: black pepper, white pepper, cinnamon, nutmeg, garlic, cumin, oregano, celery, paprika and coriander. Viscosimetry was performed in suspensions of irradiated spices and dehydrated vegetables which had been gellified by heat. Thermoluminescence (TL) is based on the transference of electrons to an excited state by radiation with emission of light when the electrons are thermally stimulated. The thermoluminescent signal of spices can be explained by the presence of mineral grains adhering on the surface of the samples. Free radicals produced by irradiation of spices were analyzed by electron spin resonance (EPR) signals. The results of this study lead to the conclusion that viscosimetry, thermoluminescence and electron spin resonance are analytical methods that can be use to detect whether spices and dehydrated vegetables were irradiated, specially when a combination of different methods was used

  1. Health, wellness and the allure of spices in the Middle Ages.

    Freedman, Paul

    2015-06-05

    During the European Middle Ages aromatic products imported from Asia and Africa were credited with both preventive and curative medical properties. In addition spices provided an image of wellness and as they were expensive and had many uses in cuisine and fragrance, they functioned as prestige consumer goods. This is an effort to look historically at a social and cultural phenomenon for the period roughly A.D. 1200-1500. Sources of information about the demand for and uses of spices include lists of materia medica, medical treatises, cookbooks, religious writings, descriptions of banquets and court ceremonial and literary works showing what might be called aspirational lifestyles. It is important to focus on the demand side of the spice trade rather than simply assuming a consistent demand and looking only at the supply (prices, routes, for example). The demand for spices must be understood in terms of their attributed medical and wellness powers, but these in turn are related to the mysterious Eastern origins of spices that enhanced their image as elite consumer products and their association with spiritual as well as medical healing.

    Peters, John C; Polsky, Sarit; Stark, Rebecca; Zhaoxing, Pan; Hill, James O

    2014-08-01

    Most adults consume more fat than is recommended in the Dietary Guidelines for Americans. We examined whether adding herbs and spices to reduced-fat foods would improve their consumer liking. We recruited adults 18-65 years old to taste three lunch conditions: full fat (FF), reduced fat with no added spice (RF), and reduced fat plus spice (RFS). Subjects rated their liking of a meatloaf entrée, vegetable side dish, pasta side dish, and overall meal on a 9-point hedonic Likert scale. Subjects came weekly for 3 weeks to consume meals and were randomized to the condition order. We enrolled 148 subjects who were predominantly female (n = 101, 68%), had a mean age of 35.9 years, and body mass index of 24.4 kg/m2. Subjects reported habitual diets as 36% of total calories from fat (2005 Block Food Frequency Questionnaire). Reducing fat content alone significantly dropped overall liking of the meal compared with FF and RFS conditions (6.29 RF vs. 7.05 FF, P spices to reduced fat foods restored liking of the overall meal, meatloaf, and vegetables to that of FF conditions, and significantly improved the liking of RF pasta. Herbs and spices can be a useful tool to improve liking of foods consistent with national guidelines. Copyright © 2014 The Author. Published by Elsevier Ltd.. All rights reserved.

  3. Dietary spices as beneficial modulators of lipid profile in conditions of metabolic disorders and diseases.

    Srinivasan, Krishnapura

    2013-04-25

    Spices are valued for their medicinal properties besides their use as food adjuncts to enhance the sensory quality of food. Dietary garlic, onion, fenugreek, red pepper, turmeric, and ginger have been proven to be effective hypocholesterolemics in experimentally induced hypercholesterolemia. The hypolipidemic potential of fenugreek in diabetic subjects and of garlic and onion in humans with induced lipemia has been demonstrated. Capsaicin and curcumin - the bioactive compounds of red pepper and turmeric - are documented to be efficacious at doses comparable to usual human intake. Capsaicin and curcumin have been shown to be hypotriglyceridemic, thus preventing accumulation of fat in the liver under adverse situations by enhancing triglyceride transport out of the liver. Capsaicin, curcumin, fenugreek, ginger, and onion enhance secretion of bile acids into bile. These hypocholesterolemic spices/spice principles reduce blood and liver cholesterol by enhancing cholesterol conversion to bile acids through activation of hepatic cholesterol-7α-hydroxylase. Many human trials have been carried out with garlic, onion, and fenugreek. The mechanism underlying the hypocholesterolemic and hypotriglyceridemic influence of spices is fairly well understood. Health implications of the hypocholesterolemic effect of spices experimentally documented are cardio-protection, protection of the structural integrity of erythrocytes by restoration of membrane cholesterol/phospholipid profile and prevention of cholesterol gallstones by modulation of the cholesterol saturation index in bile.

    Garcia, Marcelo Valle; Mallmann, Carlos Augusto; Copetti, Marina Venturini

    2018-04-01

    During their processing, spices usually remain close to the ground for drying, a fact that disposes to fungal contamination, as well as moisture transferred from the tropical environment can allow their multiplication and synthesis of mycotoxins. The objective of this study was to evaluate the presence of potentially toxigenic fungi and mycotoxins in spices marketed in Brazil. The fungal contamination was evaluated by direct plating for samples of clove, black and white peppers. Spread plate was used for the samples of rosemary, cinnamon, fennel, pepperoni pepper and oregano. Analyses were performed in triplicate in DG18 media with incubation at 25°C for 7days. The isolation and identification of fungi followed specific recommendations of culture media and incubation period for each genus. The presence of mycotoxins in spices was verified by high-performance liquid chromatography (HPLC) coupled to fluorescence. The frequency of species potentially toxigenic was high in white and black peppers with presence of both aflatoxigenic and ochratoxigenic fungi. Only rosemary and fennel showed contamination with aflatoxin B1 and there was a positive correlation (ρspices covered by Brazilian regulation of mycotoxins. On the other hand, these contaminants were present in other spices consumed by population and not mentioned in the regulation, which could be considered a cause to concern. Copyright © 2017.

  8. Oxygen-isotope trends and seawater temperature changes across the Late Cambrian Steptoean positive carbon-isotope excursion (SPICE event)

    Elrick, M.; Rieboldt, S.; Saltzman, M.; McKay, R.M.

    2011-01-01

    The globally recognized Late Cambrian Steptoean positive C-isotope excursion (SPICE) is characterized by a 3???-5??? positive ??13C shift spanning SPICE represents a widespread ocean anoxic event leading to enhanced burial/preservation of organic matter (Corg) and pyrite. We analyzed ??18O values of apatitic inarticulate brachiopods from three Upper Cambrian successions across Laurentia to evaluate paleotemperatures during the SPICE. ??18O values range from ~12.5??? to 16.5???. Estimated seawater temperatures associated with the SPICE are unreasonably warm, suggesting that the brachiopod ??18O values were altered during early diagenesis. Despite this, all three localities show similar trends with respect to the SPICE ??13C curve, suggesting that the brachiopod apatite preserves a record of relative ??18O and temperature changes. The trends include relatively high ??18O values at the onset of the SPICE, decreasing and lowest values during the main event, and an increase in values at the end of the event. The higher ??18O values during the global extinction at the onset of the SPICE suggests seawater cooling and supports earlier hypotheses of upwelling of cool waters onto the shallow shelf. Decreasing and low ??18O values coincident with the rising limb of the SPICE support the hypothesis that seawater warming and associated reduced thermohaline circulation rates contributed to decreased dissolved O2 concentrations, which enhanced the preservation/burial of Corg causing the positive ??13C shift. ?? 2011 Geological Society of America.

    Koshikawa, Tomihiko; Matsushima, Masako; Hironiwa, Takayuki; Takekawa, Tetsuya; Miyahara, Makoto

    2009-01-01

    The identification of the surviving bacteria isolated from 5 kinds of irradiated spices (all-spice, oregano, sage, paprika and black pepper) was carried out to know whether these bacteria were marker organisms to determine the efficacy of the irradiation treatment. Except in paprika, B.megaterium was detected. In allspice, paprika and black pepper B.pumilus was detected. B.cereus was detected in allspice, oregano and black pepper. Gram negative bacteria such as Methylobacterium and Enterobacter genus were also detected in oregano, sage and paprika. These bacteria were strongly resistant to radiation, and can be used as marker organisms for the determination of the efficacy of the irradiation treatment of spices. (author)

    Nordin, N; Selamat, J

    2013-01-01

    As, Cd, Pb and Hg were analysed in commonly consumed spices and herbs in Malaysia. The range of As, Cd, Pb and Hg content was 0.24-2.54, 0.23-8.07, 1.54-8.94 and 0.06-0.52 µg g(-1), respectively. The highest concentration of Cd, Pb and Hg in spices and herbs exceeded the maximum permitted proportion, which are 1, 2 and 0.05 µg g(-1), respectively. This study suggests further monitoring of Cd, Pb and Hg on daily consumption of spices and herbs and its toxicological implication for consumers since only the amount of As was lower than the permitted concentration.

  16. The corner rounding modeling technique in SPICE simulations for deeply scaled MOSFETs

    Sun Wei; Yang Dake

    2013-01-01

    This paper presents a novel poly (PC) and active (RX) corner rounding modeling approach to SPICE simulations. A set of specially designed structures was used for measurement data collection. PC and RX corner rounding equations have been derived based on an assumption that the corner rounding area is a fragment of a circle. The equations were modified to reflect the gouging effect of physical silicon wafers. The modified general equations were implemented in the SPICE model to enable the model to describe the corner rounding effect. The good fittings between the SPICE model simulation results and the silicon data demonstrated in this paper proved that the designed corner rounding model is practical and accurate.

    1985-01-01

    The effects of gamma irradiation (5.6 kGy) and ethylene oxide fumigation on the antioxidative activity of marjoram, nutmeg, paprika and black pepper were investigated. Sunflower oil in water emulsion (1:1), dark, at 30 deg C, lard, dark, at 40 deg C, lard, illuminated, at 50 deg C, and lard, dark, at 50 deg C were the substrates utilized for the investigation. Oxidation of the substrates in the presence of 0.2% (by weight) of spices were followed by the determination of peroxide value (PO) and free fatty acide value (FFA). No significant effect of irradiation on the antioxidant activities of spices was revealed. Fumigated marjoram tended to be less antioxidative in lard kept in dark storage at 60 deg C than the non-treated or irradiated spice. Marjoram and nutmeg lost their antioxidant properties in the presence of light. This loss, however, was not influenced by the irradiation or fumigation treatments. (author)

  18. Chemoluminescence measurement of 16 spices as a method to identify ionizing radiation treatment

    1984-09-01

    This report is based on a series of experiments conducted with 16 spices to find out whether the chemiluminescence intensity measurements of the reaction to luminol solution is appropriate as an indicator of treatment with ionizing radiation. For this purpose the optimum conditions of reaction were first assessed for each spice in order to determine the dependence of the chemiluminescence intensity on the radiation dose and storage time after irradiation. Only in garlic the irradiation was not able to be identified any more after 3 days of storage time. In most of the spices it is possible to take proof of radiation exposure even after storage times of more than 2 months. (orig./PW) [de

    2016-09-01

    Objective of this study was to determine the content of Cd, Hg, As and Pb in common spices traded in the Italian market, using inductively coupled plasma-mass spectrometry (ICP-MS). The results were compared with the maximum limits established by the national Legislative Decree (LD) no. 107 implementing the Council Directive 88/388/EEC and by international organisations, such as Food and Agriculture Organization (FAO) and World Health Organization (WHO). Food safety for spices was assessed considering the tolerable weekly intake (TWI) and the provisional tolerable weekly intake (PTWI), respectively, for Cd and Hg and the 95% lower confidence limit of the benchmark dose of 1% extra risk (BMDL01) for As and Pb. Investigated elements in all samples were within the maximum limits as set by the national and international normative institutions. Nevertheless, the heavy metal content of some spices exceeded the PTWI, TWI and BMDL01, which needs attention when considering consumer's health.

    The chemical compositions and antioxidant capacities of seven spices consumed in Southern Nigeria were determined. They were purchased from majors markets in the study area. Edible portions of the spices were ground into fine powder and their nutrient and phytochemical compositions determined using standard methods. Antioxidant activity were determined on aqueous extract using standard assays, namely, 1,1-diphenyl-2picrylhydrazyl (DPPH) free radical ability and ferric reducing antioxidant potential (FRAP). The spices were rich in macro-and micro-nutrients. Ricinodendron heudelotii had the highest protein (30.6%) and fat (24.6%) contents. Tetrapleura tetraptera had the least fat content. The total phenol, flavonoid and vitamin C contents differed significantly (pspices have good nutrient profile and antioxidant potentials. Their increased consumption is recommended and use as functional foods needs to be exploited. Copyright © 2017 Elsevier Ltd. All rights reserved.

  2. Circuit models and SPICE macro-models for quantum Hall effect devices

    Ortolano, Massimo; Callegaro, Luca

    2015-01-01

    Precise electrical measurement technology based on the quantum Hall effect is one of the pillars of modern quantum electrical metrology. Electrical networks including one or more QHE elements can be used as quantum resistance and impedance standards. The analysis of these networks allows metrologists to evaluate the effect of the inevitable parasitic parameters on their performance as standards. This paper presents a concise review of the various circuit models for QHE elements proposed in the literature, and the development of a new model. This last model is particularly suited to be employed with the analogue electronic circuit simulator SPICE. The SPICE macro-model and examples of SPICE simulations, validated by comparison with the corresponding analytical solution and/or experimental data, are provided. (paper)

    Akgül, A; Kivanç, M

    1988-05-01

    The inhibitory effects of 10 selected Turkish spices, oregano essential oil, thymol and carvacrol towards growth of 9 foodborne fungi were investigated in culture media with pH 3.5 and 5.5. The antifungal effects of sodium chloride, sorbic acid and sodium benzoate and the combined use of oregano with sodium chloride were also tested under the same conditions for comparison. Of the spices tested, only sodium chloride were also tested under the same conditions for comparison. Of the spices tested, only oregano at 1.0, 1.5, 2.0% (w/v) levels showed effect on all fungi. 8% (w/v) sodium chloride was less effective than oregano. Oregano essential oil, thymol or carvacrol at concentrations of 0.025% and 0.05% completely inhibited the growth of all fungi, showing greater inhibition than sorbic acid at the same concentrations. The combined use of oregano and sodium chloride exhibited a synergistic antifungal effect.

    2013-01-01

    Spice is a smoking mixture containing synthetic cannabinoids with psychoactive effects similar to herbal cannabis. It is sold on the Internet and has become popular among young people. The purpose of the present study was to investigate experiences of intoxication induced by Spice, as described on a Swedish internet-based discussion forum. A systematic search yielded 40 reports, which were analyzed using phenomenological method. A total of 7 themes (composed of 27 categories) emerged from the analysis: 1. Spice use as social ritual; 2. Social secretiveness; 3. Intoxication remarks; 4. Well-being and elation; 5. Altered perception of reality; 6. Fears and coping; 7. Unpleasant physical effects. The results show that smoking was a social activity mostly carried out in small peer-groups, and that the substances induced strong intoxication with both positive and negative effects. Despite fears and unpleasant effects, the intoxication was often considered fascinating and rewarding.

    Fundamento y objetivo Determinar la asociación entre fragilidad y mortalidad, dependencia funcional, caídas y hospitalizaciones en el Estudio Nacional de Salud y Envejecimiento en México (ENASEM). Sujetos y métodos Estudio prospectivo poblacional en México en el que se seleccionaron sujetos de 60 años o más, que fueron evaluados en las variables de fragilidad durante la primera vuelta del estudio en el año 2001 y que incluyó: dificultad para levantarse de una silla después de haber estado sentado(a) durante largo tiempo, pérdida de peso de 5 kilogramos o más en los últimos dos años y falta de energía. Los sujetos fueron catalogados como robustos, prefrágiles y frágiles cuando tenían cero, una o dos de las características anteriores, respectivamente. La mortalidad, hospitalizaciones, caídas y dependencia funcional fueron evaluadas en la segunda vuelta del estudio en el año 2003. Se calculó el riesgo relativo para cada una de las complicaciones, así como análisis multivariado con regresión de Cox para el caso de mortalidad y regresión logística para el resto. Resultados Los estados de prefragilidad y fragilidad se asociaron independientemente con mortalidad, con índices de riesgo ajustados de 1,61 (intervalo de confianza del 95% [IC 95%] 1,01-2,55) y 1,94 (IC 95% 1,20-3,13), respectivamente. Sólo el estado de fragilidad se asoció independientemente con hospitalización y dependencia funcional, con una razón de momios ajustada de 1,53 (IC 95% 1,13-2,07) y 3,07 (IC 95% 1,76-5,34), respectivamente. No hubo asociación entre los estados de prefragilidad y fragilidad con caídas. Conclusión El estado de fragilidad se asocia independientemente con mortalidad, hospitalizaciones y disfuncionalidad en actividades básicas de la vida diaria en los siguientes dos años en población mexicana.

    Spices from Egyptian local markets were irradiated with different recommended doses (0, 5, 10, 20 and 30 kGy). The spices tested included dried leaves of marjoram (Majorana hortensis Moench), rhizomes of ginger (Zingiber officinale Roscoe) and powdered hot pepper (Capsicum annum L.). The study included the isolation and identification of micro-organisms in spices following their irradiation, as well as gas chromatographic (GLC) chemical analysis for the presence and structure of volatile oils, pungent and pigment materials. The results showed that hot pepper was contaminated more (9.2x10 5 /g) than marjoram (4.2x10 3 /g) and ginger (14.3x10 3 /g) with respect to total aerobic bacterial content. The total contents of moulds were 4.8x10 3 /g, 5.7x10 3 /g and 19x10 3 /g in the same spices, respectively, but the pathogenic moulds and bacterial strains differed according to the type of spice. Irradiation at 10, 20 and 30 kGy caused complete elimination of mirco-organisms, whereas 5 kGy was less effective. With the GLC method chosen 18 and 50 compounds could be detected in the extracts of marjoram and ginger, respectively; γ-terpinen and zingiberen being the major compounds in marjoram and ginger, respectively. A noticeable reduction was observed in the amount of terpenes present in irradiated marjoram; they were converted to monoterpensalcohols. Ginger was more sensitive to irradiation, especially at high doses, but moderate changes were detected at low doses (5 and 10 kGy). A slight, but significant effect on the capsaicin (pungent compound) in hot pepper was observed following irradiation, whereas no changes in total pigments resulted at any dose. These results prove that 10 kGy is a sufficiently high dose to eliminate the microorganisms in spices, causing only slight changes in the flavouring materials. (orig.)

    Spices and condiments are an important part of human history and nutrition, and have played an important role in the development of most cultures around the world. According to the Codex Alimentarius, the category of salts, spices, soups, sauces, salads, and protein products includes substances added to foods to enhance aroma and taste. Spices have been reported to have health benefits as antioxidant, antibiotic, antiviral, anticoagulant, anticarcinogenic, and anti-inflammatory agents. Health claims about the benefits of condiments for disease prevention or health improvement need to be science based and extensively supported by evidence; data on their preventive or protective potential in humans are currently limited. The condiments market has been growing continuously over the last few years, with the quantity of products sold under the category of sauces, dressings, and condiments during the period 2008-2013 increasing from 31,749,000 to 35,795,000 metric tons. About 50 of the 86 spices produced in the world are grown in India. From 2008 to 2013, the United States was the largest importer of spices, followed by Australia, the United Kingdom, Canada, and Russia. The main buyers of fish sauce are Vietnam and Thailand, with purchases of 333,000 and 284,000 metric tons in 2013, respectively. The sauces and condiments category is dynamic, with large differences in consumption in habits and practices among countries. This paper aims to establish definitions and discuss potential health benefits, consumption patterns, and global markets for sauces, spices, and condiments. © 2016 New York Academy of Sciences.

    The scattering of X-rays at low angles (LAXS) is a technique dominated by the coherent scattering process. One characteristic observation of low-angle coherent scattering is the so-called molecular interference effect, being characterized by the presence of one or more peaks in the forward direction of scattering. In the present study, LAXS profiles from five different spices are carefully measured in order to establish characteristic scattering signatures. Samples of Ceylon cinnamon, cumin, nutmeg, paprika and black pepper were bought in local market in Rio de Janeiro, Brazil. The LAXS patterns were obtained using a Shimadzu DRX 6000 diffractometer in reflection geometry. Coherent scattering patterns are measured for the samples for θ=5-35 o . The data were collected in 0.05 o increments every 3 s. In order to evaluate the possible molecular structure changes caused to the irradiation procedure, the signatures obtained for control (non-irradiated) spices were compared with spice samples irradiated with different doses varying from 3 to 40 kGy. The LAXS patterns of all samples were obtained after 30, 60, 90, 120 days to evaluate the effect of storage period. Scattering profiles from spices irradiated with different irradiation doses were obtained and the results compared. For each spice, there is no considerable deviation in shape in function of the irradiation dose. It indicates that the molecular structure of each analyzed spices is preserved considering the dose range chosen. The results show that the molecular structure was found to be stable during storage at the ambient temperature for up to 4 months

  11. Beneficial effects of herbs, spices and medicinal plants on the metabolic syndrome, brain and cognitive function.

    Panickar, Kiran S

    2013-03-01

    Herbs and spices have been used since ancient times to not only improve the flavor of edible food but also to prevent and treat chronic health maladies. While the scientific evidence for the use of such common herbs and medicinal plants then had been scarce or lacking, the beneficial effects observed from such use were generally encouraging. It is, therefore, not surprising that the tradition of using such herbs, perhaps even after the advent of modern medicine, has continued. More recently, due to an increased interest in understanding the nutritional effects of herbs/spices more comprehensively, several studies have examined the cellular and molecular modes of action of the active chemical components in herbs and their biological properties. Beneficial actions of herbs/spices include anti-inflammatory, antioxidant, anti-hypertensive, gluco-regulatory, and anti-thrombotic effects. One major component of herbs and spices is the polyphenols. Some of the aforementioned properties are attributed to the polyphenols and they are associated with attenuating the metabolic syndrome. Detrimental changes associated with the metabolic syndrome over time affect brain and cognitive function. Metabolic syndrome and type-2 diabetes are also risk factors for Alzheimer's disease and stroke. In addition, the neuroprotective effects of herbs and spices have been demonstrated and, whether directly or indirectly, such beneficial effects may also contribute to an improvement in cognitive function. This review evaluates the current evidence available for herbs/spices in potentially improving the metabolic syndrome, as well as their neuroprotective effects on the brain, and cognitive function in animal and human studies.

  12. The microbiological quality of ready-to-eat foods with added spices.

    2003-03-01

    A microbiological study of ready-to-eat foods with added spices or spice ingredients was undertaken to identify any risk factors in the production, storage and display of this product and to establish their effect on microbiological quality. Examination of 1946 ready-to-eat foods from sandwich bars, cafés, public houses, restaurants, specialist sandwich producers, bakers, delicatessens, market stalls and mobile vendors found that 1291 (66%) were of satisfactory/acceptable microbiological quality, 609 (32%) were of unsatisfactory quality, and 46 (2%) were of unacceptable quality. Unacceptable results were due to high levels of B. cereus and/or other Bacillus spp. (>/=10(5) cfu g(-1)). Unsatisfactory results were mostly due to high Aerobic Colony Counts (up to >/=10(7) cfu g(-1)), Enterobacteriaceae (>/=10(4) cfu g(-1)), Escherichia coli (>/=10(2) cfu g(-1)), and Bacillus spp (>/=10(4) cfu g(-1)). Examination of 750 spices and spice ingredients revealed that B. cereus were present in 142 (19%) samples, other Bacillus spp. in 399 (53%) samples, and Salmonella spp. (S. enteritidis PT 11) in one (/=10(4) cfu g(-1)) of B. cereus and/or other Bacillus spp., and appeared to be associated with the corresponding ready-to-eat foods containing similar high counts of these organisms (Pquality of ready-to-eat foods to which spices or spice ingredients have been added was associated with premises that had management food hygiene training and hazard analysis in place. Poor microbiological quality was associated with preparation on the premises, premises type, little or no confidence in the food business management of food hygiene, and small premises as indicated by local authority inspectors' confidence in management and consumer at risk scores.

The total contents of moulds were 4.8x10{sup 3}/g, 5.7x10{sup 3}/g and 19x10{sup 3}/g in the same spices, respectively, but the pathogenic moulds and bacterial strains differed according to the type of spice. Irradiation at 10, 20 and 30 kGy caused complete elimination of mirco-organisms, whereas 5 kGy was less effective. With the GLC method chosen 18 and 50 compounds could be detected in the extracts of marjoram and ginger, respectively; {gamma}-terpinen and zingiberen being the major compounds in marjoram and ginger, respectively. A noticeable reduction was observed in the amount of terpenes present in irradiated marjoram; they were converted to monoterpensalcohols.

A slight, but significant effect on the capsaicin (pungent compound) in hot pepper was observed following irradiation, whereas no changes in total pigments resulted at any dose. These results prove that 10 kGy is a sufficiently high dose to eliminate the microorganisms in spices, causing only slight changes in the flavouring materials. (orig.)

    2012-10-01

    Spices are rich sources of antioxidants due to the presence of phenols and flavonoids. In this study, the DNA protecting activity and inhibition of nicotine-induced cancer cell migration of 9 spices were analysed. Murine fibroblasts (3T3-L1) and human breast cancer (MCF-7) cells were pre-treated with spice extracts and then exposed to H₂O₂ and nicotine. The comet assay was used to analyse the DNA damage. Among the 9 spices, ginger, at 50 μg/ml protected against 68% of DNA damage in 3T3-L1 cells. Caraway, cumin and fennel showed statistically significant (pspices reduced this migration. Pepper, long pepper and ginger exhibited a high rate of inhibition of cell migration. The results of this study prove that spices protect DNA and inhibit cancer cell migration.

    2001-01-01

    lrradiation of 6 kGy could make the MPN of coliform bacteria in irradated spices and dehydrated vegetables meet the demands of the national microbiological examination of food hygiene. No new irradiation-resistance organism in coliform bacteria was found in 188 spices samples treated. The mistake in the MPN of coliform bacteria detection was caused mainly by operation. The main cause was that the detected bacteria for lactose refermentation and Gram-stain tests were not picked from the same colony. (authors)

    2013-12-01

    We performed a laboratory analysis of spices sold in Sri Lanka for lead content. Samples of curry powder, chili powder and turmeric powder from seven provinces, collected using the market basket survey method, underwent atomic absorption spectrometry. Blanks and standards were utilised for instrument calibration and measurement accuracy. The results were validated in two different laboratories. All samples were found to have lead levels below the US Food and Drug Administration's action level of 0.5 μg/g. Spices sold in Sri Lanka contain lead concentrations that are low and within the stipulated safety standards.

  1. Más allá de las limitaciones económicas y legales de la dependencia: caso de Castilla y León

    María Cristina Fernández Ramos

    2013-10-01

    Full Text Available La falta de autonomía es una situación que se presenta con mayor frecuencia dentro del colectivo de personas mayores. Para paliarlo en España se encuentra vigente la Ley de Dependencia, donde se confiere un grado de gestión de prestaciones al sector privado y a las Comunidades Autónomas. Entre ellas, Castilla y León debido a su población tan envejecida debiera ser uno de los territorios más interesados en desarrollar la normativa relativa a la dependencia. Por otra parte, el momento económico actual ha dado como resultado fuertes recortes del gasto público. En particular, el capítulo de Atención a la Dependencia ha sido especialmente afectado. Además, el incremento en los precios de los servicios que se prestan en este ámbito, lleva a considerar que las ayudas públicas no son suficientes. Por ello, se deberían estudiar opciones que las complementen. El desarrollo normativo de la dependencia otorga un derecho subjetivo de carácter universal a los individuos y otorga a las empresas, la seguridad jurídica necesaria para poder operar en los mercados. Del estudio del marco normativo tanto a nivel estatal como a nivel regional, se puede concluir que es factible desarrollar productos financieros y actuariales que limen las diferencias entre los territorios de las comunidades autónomas. The lack of independence is a frequent problem faced by the elderly population. In order to combat this situation, the Spanish Dependent Persons´ Law decrees that benefits for elderly people be managed by the private sector and/or local government. Among the Spanish regions, Castilla and León being a region with one of the highest number of elderly citizens in the Spanish state, has a vested interest in providing adequate coverage for the elderly. The current economic climate has led to severe cuts in public spending. Spending on Dependent Persons´ benefits has been particularly affected. As the result of a concurrent increase in the cost of those

Se aplica la metodología de la cointegración de Engle y Granger (1987 y de Johansen(1988 para contrastar la hipótesis de la paridad de tipos de interés no cubierta y se llega a la conclusión de que ambas políticas están cointegradas porque mantienen una relación de equilibrio a largo plazo. También se deduce una dependencia de la política del Banco de Inglaterra de la política del Banco Central Europeo, lo que confirma la importancia y el liderazgo de la Unión Económica y Monetaria.This study is to investigate the long-run relationship and dependence between the UME´s monetary policy and non-euro zone´s monetary policy for the period from January 4, 1999 to September 30, 2009. We use cointegration methodology to test the Uncovered Interest Parity Hypothesis and the results indicate a long-run cointegration and empirical evidence testifies a leader-follower pattern between the two central banks. According to this pattern, the Bank of England does follow the European Central Bank.

    Full Text Available Una de las contingencias para causar la prestación en un plan de pensiones es la dependencia en grado de severa o gran dependencia. Su inclusión en las especificaciones conlleva la necesidad de realizar una serie de consideraciones para ser contemplada como contingencia.El objetivo de este trabajo es desarrollar la metodología para incorporar esta prestación en un plan de pensiones que ya se encuentre implantado y tenga en cuenta la mortalidad inherente al dependiente severo o gran dependiente. Esto conduce a un sistema que permite una equivalencia financiero-actuarial que determine la prestación actuarialmente equivalente para el beneficiario fijándose un factor de conversión equivalente. De este modo se consigue un sistema justo y equitativo con cada situación personal del dependiente, entendido como una adaptación de la pensión a la situación biométrica del beneficiario favoreciendo el aspecto social de la prestación. One of the contingencies into a pension plan is the dependence in high degrees (severe or great dependence. The inclusion into the pension scheme asks a series of considerations to face this contingency. The aim of this work is to develop the methodology to incorporate this benefit into a pension plan that is running and bears in mind the different mortality rates between the beneficiary and the dependent. Upon this point of view, the system allows a financial - actuarial equivalence to determine the equivalent benefit for the beneficiary under an equivalent actuarial factor. Thus, there is obtained an equitable system according to every personal situation. That is doing an adjustment of the benefit under biometric situation of the beneficiary adding a social aspect to the pension plan.

    2017-12-01

    For the past 25 years, polar-orbiting satellite radar altimeters have provided a valuable record of ice sheet elevation change and mass balance. One of the principle challenges associated with radar altimetry comes from the relatively large ground footprint of conventional pulse-limited radars, which reduces their capacity to make measurements in areas of complex topographic terrain. In recent years, progress has been made towards improving ground resolution, through the implementation of Synthetic Aperture Radar (SAR), or Delay-Doppler, techniques. In 2010, the launch of CryoSat-2 heralded the start of a new era of SAR Interferometric (SARIn) altimetry. However, because the satellite operated in SARIn and LRM mode over the ice sheets, many of the non-interferometric SAR altimeter processing techniques have been optimized for water and sea ice surfaces only. The launch of Sentinel-3, which provides full non-interferometric SAR coverage of the ice sheets, therefore presents the opportunity to further develop these SAR processing methodologies over ice sheets. Here we present results from SPICE, a 2 year study that focuses on (1) developing and evaluating Sentinel-3 SAR altimetry processing methodologies over the Polar ice sheets, and (2) investigating radar wave penetration through comparisons of Ku- and Ka-band satellite measurements. The project, which is funded by ESA's SEOM (Scientific Exploitation of Operational Missions) programme, has worked in advance of the operational phase of Sentinel-3, to emulate Sentinel-3 SAR and pseudo-LRM data from dedicated CryoSat-2 SAR acquisitions made at the Lake Vostok, Dome C and Spirit sites in East Antarctica, and from reprocessed SARIn data in Greenland. In Phase 1 of the project we have evaluated existing processing methodologies, and in Phase 2 we are investigating new evolutions to the Delay-Doppler Processing (DDP) and retracking chains. In this presentation we (1) evaluate the existing Sentinel-3 processing chain by

    Olive oil flavouring with aromatic plants and spices is a traditional practice in Mediterranean gastronomy. The aim of this work was to compare the influence of two different flavouring techniques (infusion of spices into the oil vs. combined malaxation of olives paste and spices) on chemical and sensory quality of flavoured olive oil. In particular, oxidative and hydrolytic degradation (by routine and non-conventional analyses), phenolic profiles (by HPLC), volatile compounds (by SPME-GC/MS), antioxidant activity, and sensory properties (by a trained panel and by consumers) of the oils were evaluated. The obtained results evidenced that the malaxation method was more effective in extracting the phenolic compounds, with a significantly lower level of hydrolysis of secoiridoids. As a consequence, antioxidant activity was significantly lower in the oils obtained by infusion, which were characterized by a higher extent of the oxidative degradation. The volatile compounds were not significantly influenced by changing the flavouring method, apart for sulfur compounds that were more abundant in the oils obtained by the combined malaxation method. From a sensory point of view, more intense bitter and pungent tastes were perceived when the infusion method was adopted. Copyright © 2016 Elsevier Ltd. All rights reserved.

  10. Locomotion of Mexican jumping beans

    West, Daniel M; K Lal, Ishan; Leamy, Michael J; Hu, David L

    2012-01-01

    The Mexican jumping bean, Laspeyresia saltitans, consists of a hollow seed housing a moth larva. Heating by the sun induces movements by the larva which appear as rolls, jumps and flips by the bean. In this combined experimental, numerical and robotic study, we investigate this unique means of rolling locomotion. Time-lapse videography is used to record bean trajectories across a series of terrain types, including one-dimensional channels and planar surfaces of varying inclination. We find that the shell encumbers the larva's locomotion, decreasing its speed on flat surfaces by threefold. We also observe that the two-dimensional search algorithm of the bean resembles the run-and-tumble search of bacteria. We test this search algorithm using both an agent-based simulation and a wheeled Scribbler robot. The algorithm succeeds in propelling the robot away from regions of high temperature and may have application in biomimetic micro-scale navigation systems. (paper)

  11. Mexican gems as thermoluminescent dosimeters

    Azorin N, J.

    1979-01-01

    The possibility of using naturally ocurring mexican gems as thermoluminescent dosimeters (TLD) was investigated. Twelve types of gems were irradiated with X and gamma rays in order to determinate their dosimetric properties. Three of these gems showed favorable thermoluminescent characteristics compared with commercial thermoluminescent dosimeters. The plots of their thermoluminescent response as a function of gamma dose are straight lines on full log paper in the dose range 10 -2 to 10 2 Gy. The energy dependence is very strong to low energies of the radiation. Their fading was found to be about 5%/yr. and they may be annealed as reused without loss in sensitivity. Therefore, these gems can be used as X and gamma radiation dosimeters. (author)

    1996-01-01

    Full Text Available The present work involves integration of the simulation stage of design of a VLSI circuit and its testing stage. The SPICE simulator, TEK LV500 ASIC Design Verification System, and TekWaves, a test program generator for LV500, were integrated. A software interface in ‘C’ language in UNIX ‘solaris 1.x’ environment has been developed between SPICE and the testing tools (TekWAVES and LV500. The function of the software interface developed is multifold. It takes input from either SPICE2G.6 or SPICE 3e.1. The output generated by the interface software can be given as an input to either TekWAVES or LV500. A graphical user interface has also been developed with OPENWlNDOWS using Xview tool kit on SUN workstation. As an example, a two phase clock generator circuit has been considered and usefulness of the software demonstrated. The interface software could be easily linked with VLSI design such as MAGIC layout editor.

  17. Heavy Metal Contents in Spices from Markets in Sarajevo, Bosnia and Herzegovina

    Huremović, J.

    2014-05-01

    Full Text Available Spices are some of the most common foods in the human diet around the world. Spices are dried parts of plants used often as diet components to improve aroma and acceptability of food. The aim of this work was to determine the contents of seven heavy metals (Cr, Cu, Fe, Mn, Ni, Pb and Zn in spices available at local markets in Sarajevo. Metal concentrations in six spice samples (black pepper (Piper nigrum, basil (Ocimum basilicum, oregano (Oreganum vulgaris, paprika (Capsicum annuum, parsley (Petroselinum crispum and rosemary (Rosmarinus officinalis were determined by flame atomic absorption spectrometry. The content of chromium and nickel in all samples was below 5 mg kg-1 . Copper levels were in the range of 2.36-19.47 mg kg-1 , iron 6.80-785.56 mg kg-1 , manganese 6.14-59.36 mg kg-1 , lead 0.74-20.35 and zinc 6.93-85.44 mg kg-1 . These results were in agreement with other published data except in the case of Pb which content was slightly higher. Daily intake of different metals was calculated and compared with the MRL values given by ATSDR (2013. The content of lead in most of the samples was above the maximum permitted concentrations recommended by WHO and national regulations of Bosnia and Herzegovina.

  20. Active vibration control testing of the SPICES program: final demonstration article

    Dunne, James P.; Jacobs, Jack H.

    1996-05-01

    The Synthesis and Processing of Intelligent Cost Effective Structures (SPICES) Program is a partnership program sponsored by the Advanced Research Projects Agency. The mission of the program is to develop cost effective material processing and synthesis technologies to enable new products employing active vibration suppression and control devices to be brought to market. The two year program came to fruition in 1995 through the fabrication of the final smart components and testing of an active plate combined with two trapezoidal rails, forming an active mount. Testing of the SPICES combined active mount took place at McDonnell Douglas facilities in St. Louis, MO, in October-December 1995. Approximately 15 dB reduction in overall response of a motor mounted on the active structure was achieved. Further details and results of the SPICES combined active mount demonstration testing are outlined. Results of numerous damping and control strategies that were developed and employed in the testing are presented, as well as aspects of the design and fabrication of the SPICES active mount components.

  1. Identification of irradiated spices by the use of thermoluminescence method (TL)

    Sharifzadeh, M.; Sohrabpour, M. (Atomic Energy Organization of Iran, Teheran (Iran, Islamic Republic of))

    In this paper the results of the investigation of identification of irradiated spices by the use of thermoluminescence method is reported. The materials used were black and red peppers, turmeric, cinnamon, and garlic powder. Gamma Cell 220 was used for irradiating samples at dose values of 2.5, 5, 7.5 and 10 kGy respectively. The TL intensity of the unirradiated spices as well as the fading characteristics of the irradiated samples having received a dose of 10 kGy have been measured. Post-irradiation temperature treatment of the irradiated (10 kGy) and unirradiated samples at 60[sup o]C and 100[sup o]C for 24 hours have also been performed. The results show that the TL intensities of unirradiated and irradiated samples from different batches of each spice are fairly distributed. A reasonable TL intensity versus dose has been observed in nearly all cases. Based on the observation made it is possible to distinguish irradiated spices after (4-9) months post-irradiation.

    Spintronics aims at extending the possibility of conventional electronics by using not only the charge of the electron but also its spin. The resulting spintronic devices, combining the front-end complementary metal oxide semiconductor technology of electronics with a magnetic back-end technology, employ magnetic tunnel junctions (MTJs) as core elements. With the intent of simulating a circuit without fabricating it first, a reliable MTJ electrical model which is applicable to the standard SPICE (Simulation Program with Integrated Circuit Emphasis) simulator is required. Since such a model was lacking so far, we present a MTJ SPICE model whose magnetic state is written by using the spin-transfer torque effect. This model has been developed in the C language and validated on the Cadence Virtuoso Platform with a Spectre simulator. Its operation is similar to that of the standard BSIM (Berkeley Short-channel IGFET Model) SPICE model of the MOS transistor and fully compatible with the SPICE electrical simulator. The simulation results obtained using this model have been found in good accord with those theoretical macrospin calculations and results.

    2014-09-01

    Changes in cumin and chili powder from India resulting from electron-beam irradiation were investigated using 3 analytical methods: electronic nose (E-nose), Fourier transform infrared (FTIR) spectroscopy, and electron paramagnetic resonance (EPR) spectroscopy. The spices had been exposed to 6 to 14 kGy doses recommended for microbial decontamination. E-nose measured a clear difference in flavor patterns of the irradiated spices in comparison with the nonirradiated samples. Principal component analysis further showed a dose-dependent variation. FTIR spectra of the samples showed strong absorption bands at 3425, 3007 to 2854, and 1746 cm(-1). However, both nonirradiated and irradiated spice samples had comparable patterns without any noteworthy changes in functional groups. EPR spectroscopy of the irradiated samples showed a radiation-specific triplet signal at g = 2.006 with a hyper-fine coupling constant of 3 mT confirming the results obtained with the E-nose technique. Thus, E-nose was found to be a potential tool to identify irradiated spices. © 2014 Institute of Food Technologists®

  6. Potent Chemopreventive/Antioxidant Activity Detected in Common Spices of the Apiaceae Family.

    Jeyabalan, Jeyaprakash; Aqil, Farrukh; Soper, Lisa; Schultz, David J; Gupta, Ramesh C

    2015-01-01

    Spices are used worldwide, particularly in the Asian and Middle Eastern countries, and considered protective against degenerative diseases, including cancer. Here, we report the efficacy of aqueous and non-aqueous extracts of 11 Apiaceae spices for free radical-scavenging activity and to inhibit cytochrome P450s in two separate reactions involving: 1) 4-hydroxy-17ß-estradiol (4E2), DNA, and CuCl2 and 2) 17ß-estradiol, rat liver microsomes, cofactors, DNA and CuCl2. Oxidative DNA adducts resulting from redox cycling of 4E2 were analyzed by (32)P-postlabeling. Aqueous (5 mg/ml) and non-aqueous extracts (6 mg/ml) substantially inhibited (83-98%) formation of DNA adducts in the microsomal reaction. However, in nonmicrosomal reaction, only aqueous extracts showed the inhibitory activity (83-96%). Adduct inhibition was also observed at five-fold lower concentrations of aqueous extracts of cumin (60%) and caraway (90%), and 10-fold lower concentrations of carrot seeds (76%) and ajowan (90%). These results suggests the presence of 2 groups of phytochemicals: polar compounds that have free radical-scavenging activity and lipophilic compounds that selectively inhibit P450 activity associated with estrogen metabolism. Because most of these Apiaceae spices are used widely with no known toxicity, the phytochemicals from the Apiaceae spices used in foods may be potentially protective against estrogen-mediated breast cancer.

  8. Evaluation of the Antioxidant Activity of Extracts and Active Principles of Commonly Consumed Indian Spices.

    Patra, Kartick; Jana, Samarjit; Mandal, Deba Prasad; Bhattacharjee, Shamee

    2016-01-01

    Accumulating evidence suggests that free radical reactions play a key part in the development of degenerative diseases and that an antioxidant-rich diet is a major defense against these free radical reactions. In this study, we explore comparative antioxidant capacities of extracts of some commonly used in Indian spices (anise, cardamom, Ceylon cinnamon, and clove) along with their purified components (anethole, eucalyptol, cinnamaldehyde, and eugenol, respectively). Eugenol shows the highest 1,1-diphenyl-2-picrylhydrazyl, hydroxyl, and superoxide scavenging and reducing power activity in terms of weight; however, this was not found when compared in terms of equivalence. Extracts of the other three spices were found to be more potent antioxidants than their corresponding active components. Interestingly, clove extract, despite possessing the highest phenol and flavonoid content, is not the most potent radical scavenger. At low concentrations, both the crude extracts and their purified components (except for anethole and eugenol) have low hemolytic activity, but at higher concentrations purified components are more toxic than their respective crude extract. This study suggests that spices as a whole are more potent antioxidants than their purified active components, perhaps reflecting the synergism among different phytochemicals present in spice extracts.

  9. Nation-Based Occurrence and Endogenous Biological Reduction of Mycotoxins in Medicinal Herbs and Spices.

    Do, Kee Hun; An, Tae Jin; Oh, Sang-Keun; Moon, Yuseok

    2015-10-14

    Medicinal herbs have been increasingly used for therapeutic purposes against a diverse range of human diseases worldwide. Moreover, the health benefits of spices have been extensively recognized in recent studies. However, inevitable contaminants, including mycotoxins, in medicinal herbs and spices can cause serious problems for humans in spite of their health benefits. Along with the different nation-based occurrences of mycotoxins, the ultimate exposure and toxicities can be diversely influenced by the endogenous food components in different commodities of the medicinal herbs and spices. The phytochemicals in these food stuffs can influence mold growth, mycotoxin production and biological action of the mycotoxins in exposed crops, as well as in animal and human bodies. The present review focuses on the occurrence of mycotoxins in medicinal herbs and spices and the biological interaction between mold, mycotoxin and herbal components. These networks will provide insights into the methods of mycotoxin reduction and toxicological risk assessment of mycotoxin-contaminated medicinal food components in the environment and biological organisms.

    2017-03-01

    Full Text Available Introduction There is a growing interest in determining the concentration of various elements in food spices. In the present study, the instrumental neutron activation analysis (INAA was employed to measure the trace elements in 11 commonly food spices consumed in Tehran, Iran. Materials and Methods The levels of K, Mn, Na, Cl, V, Br, Al, and As were determined and their effects on human health were discussed. The results were compared with the values reported in the literature. The accuracy and precision of the analytical procedure was estimated by analyzing the Lichen (IAEA-336 reference material. Results The concentrations of the measured elements in the spices were 3850-29157, 10-335, 153-2849, 186-3063, 0.2-2.8, 2.1-58.7, and 72-2102 ppm for K, Mn, Na, Cl, V, Br, and Al, respectively. As was only detected in thyme (0.8 ppm and plantain (0.42 ppm. Conclusion As the findings of the present study indicated, the concentrations of K and Na in the black pepper, garlic, and ginger were significantly higher than the values reported in other countries. The Mn levels in the black pepper and garlic consumed in Tehran were comparable with those in Poland. Furthermore, the concentration of As in these spices were lower than the maximum permissible limit.

  13. Prevalence, serotype diversity, and antimicrobial resistance of Salmonella in imported shipments of spice offered for entry to the United States, FY2007-FY2009.

    Van Doren, Jane M; Kleinmeier, Daria; Hammack, Thomas S; Westerman, Ann

    2013-06-01

    In response to increased concerns about spice safety, the U.S. FDA initiated research to characterize the prevalence of Salmonella in imported spices. Shipments of imported spices offered for entry to the United Sates were sampled during the fiscal years 2007-2009. The mean shipment prevalence for Salmonella was 0.066 (95% CI 0.057-0.076). A wide diversity of Salmonella serotypes was isolated from spices; no single serotype constituted more than 7% of the isolates. A small percentage of spice shipments were contaminated with antimicrobial-resistant Salmonella strains (8.3%). Trends in shipment prevalence for Salmonella associated with spice properties, extent of processing, and export country, were examined. A larger proportion of shipments of spices derived from fruit/seeds or leaves of plants were contaminated than those derived from the bark/flower of spice plants. Salmonella prevalence was larger for shipments of ground/cracked capsicum and coriander than for shipments of their whole spice counterparts. No difference in prevalence was observed between shipments of spice blends and non-blended spices. Some shipments reported to have been subjected to a pathogen reduction treatment prior to being offered for U.S. entry were found contaminated. Statistical differences in Salmonella shipment prevalence were also identified on the basis of export country. Published by Elsevier Ltd.

  14. A comparative assessment of the role of anoxia during the Cambrian SPICE event

    LeRoy, M.; Gill, B. C.; Sperling, E. A.

    2017-12-01

    The Cambrian SPICE (Steptoean Positive Carbon Isotope Excursion) is recognized as a major oceanographic event recorded in globally-distributed stratigraphic sections as positive isotopic excursions in marine carbonates (δ13Ccarb), organic matter (δ13Corg), sulfate (δ34SCAS) and pyrite (δ34Spy). A proposed mechanism for these observed isotopic trends is that a transient increase in the areal extent of anoxic conditions within the oceans fostered enhanced burial of organic carbon and pyrite. However, direct sedimentary (e.g., abundant black shale) and geochemical (e.g., redox proxy) evidence for such a shift is scant. While the antiquity of this event is likely responsible for loss of much of this evidence, through destruction by tectonic processes, a number of stratigraphic successions suitable for investigating this hypothesis exist. Here we explore the relationship between anoxia and the SPICE using previously published and novel data generated from core material from three sedimentary basins distributed along the margins of the Iapetus Ocean. The units studied are: the Nolichucky Formation of eastern Laurentia, the Alum Shale of Baltica, and the Outwoods Shale of Avalonia. Our iron speciation data indicate consistently oxic conditions prior to the SPICE along Laurentia, while Avalonia was oxic with intervals of anoxia, and Baltica was persistently anoxic. With the initiation of the SPICE, anoxic conditions intensified in Laurentia and Avalonia and continued to persist in Baltica. This redox shift was coupled with a sharp rise in δ34Spy at all three locations. Average total organic carbon (TOC) showed little change in relation to the SPICE at the Laurentia location ( 0.15 wt%), but showed an increase in conjunction with the excursion in both the Avalonia ( 1 to 1.5 wt%) and Baltica ( 8 to 12 wt%) sections. Large differences in nutrient availability and sedimentation rates are likely responsible for the between-site disparity in TOC, while overall, anoxia

    2015-01-01

    Full Text Available The effect of selected spices included in the recipe of rye-buckwheat cakes on sensory quality, nutritional value, and Maillard reaction (MR products formation was addressed in this study. The cakes with cloves, nutmeg, allspice, cinnamon, vanilla, and spice mix addition revealed the highest overall quality values. Cakes enriched with cloves, allspice, and spice mix showed the highest rutin content and almost threefold higher available lysine contents whereas cakes enhanced with mix, cloves, and cinnamon were the richest source of phenolic compounds. The highest antioxidant capacity showed cakes with cloves and spice mix. The furosine, a marker of early stage of MR, was decreased in cakes with cloves, allspice, spice mix, and vanilla whereas fluorescent intermediatory compounds were reduced in cakes enhanced with cloves, allspice, and cinnamon. In contrast, browning index was increased as compared to cakes without spices. The FAST index was significantly lowered in all cakes enriched with spices, especially with cloves, allspice, and mix addition. The presence of cloves, allspice, and vanilla in cake formula was the most efficient in acrylamide strategy. It can be suggested that cloves, allspice, and vanilla might be used for production of safety and good quality cakes.

  16. Viscosity measurement - probably a means for detecting radiation treatment of spices. Viskositaetsmessung - ein Verfahren zur Identifizierung strahlenbehandelter Gewuerze

    Heide, L; Albrich, S; Boegl, K W; Mohr, E; Wichmann, G

    1987-12-01

    The viscosity of 13 different spices and dried vegetables in total was measured. Optimal conditions were first determined for each product, i.e. concentration, pH-value, temperature, particle size and soaking time. For method evaluation, examinations were primarily performed to study the effect of storage, the reproducibility and the influence of the different varieties of the same spice. In supplement, for pepper, the viscosity was measured as a function of radiation dose. In summation, significant changes in the gel forming capability after irradiation could be observed after preliminary experiments in 8 dried spices (ginger, carrots, leek, cloves, pepper, celery, cinnamon and onions). With 3 spices (ginger, pepper and cinnamon) could the results from examining all different varieties of the same spice be substantiated. An additional influence of storage time on viscosity could not be proved during the investigative period of 8 months. Generally seen, there is no possibility of being able to identify an irradiated spice on the basis of viscosity measurements alone, since the difference between the varieties of one and the same spice is considerably great. However, radiation treatment can be reliably excluded with ginger, pepper and cinnamon, if the viscosities are high (10-20 Pa x s).

    K2 and Spice consist of an herbal blend of plant matter and chemical synthetic cannabinoids. These substances emerged in the early 2000s as a popular alternative to marijuana among youth and young adults. This study sought to identify rates and correlates of K2 and Spice at college entry and first use during college. In Fall 2010, 3146 students at 11 colleges in North Carolina and Virginia were recruited to participate in a longitudinal cohort survey. The cohort was invited to participate in a total of six surveys over their college career. Random-effects logistic regression models were used to identify factors associated with lifetime K2 and Spice use at college entry and first use during college, adjusting for clustering within schools and sample weights. Weighted lifetime prevalence of K2 and Spice use at college entry was 7.6%. An additional 6.6% of students reported first use during college. By the cohort's fourth year, 17.0% reported lifetime K2 and Spice use. While lifetime prevalence increased, past 6-month prevalence decreased substantially over time. K2 and Spice use at college entry was associated with sensation seeking; hookah, marijuana, and illicit drug use; and low religiosity. First use during college was associated with having a father with less than a four-year degree; alcohol and hookah use. Universities should ensure that prevention efforts address current substance use, including K2/Spice, and that treatment options are available for first year students who use substances.

    The objective of this study was to evaluate preferences and frequency choice of commercially available powdered spices, applied to the dishes prepared at home by professionally working persons as well as factors which determine the acceptance of innovative changes in relation to the number and type of components used for their manufacturing. It was shown that above 80% mixtures of spices contained except vegetable spices also other flavourings, spice-products and functional additives but mostly monosodium glutamate (MSG) and sodium chloride. The respondents mostly accepted multicomponent powdered spices, manufactured with the application of new technologies which permitted creation original tastes and next their health-promoting role as well as convenience in use however, without changes in recipe. The women declared that to the dishes prepared at home usually applied herb spices. Conversely, the men mostly liked and often chose spices with savoury and distinctive taste and most willingly multicomponent ones which were suitable for flavour improvement of many dishes.

  19. Effect of spices commercial mixture with GDL on the quality of fermented dry-cured sausages

    Miroslav Kročko

    2016-06-01

    Full Text Available The main fermented meat products are fermented sausages in which lactic acid bacteria (LAB are the essential agents of the ripening process. Their application as starter organisms ensures the dominance of the starter during the whole ripening process. However, when no starter cultures are used, direct addition of acids like a glucono-delta-lactone (GdL is preferred. The goal of this study was to determine the influence of commercial spices mixtur (containing GdL on selected technological parameters of fermented dry-cured sausages - Danube sausage in comparison with currently available conventional spices. Comparison was evaluated also with addition of starter cultures. Determinations of technological (value of pH, water activity, color and microbiological properties (count of Lactobacillus spp., Enterobacteriaceae family, yeasts and moulds were realized after 24 hours, 5 and 30 days. The sensory analysis of sausages was carried out after 30 days of ripening process. In sausages with the addition of commercial spice mixture in combination with starter culture were determined the lowest values of pH and aw at the end of ripening process (30 days. Bacteria of Enterobacteriaceae family were occurred in the samples with the addition of currently available conventional spices at the beginning of ripening, but after 5 days of ripening were bacteria of this family not detected. The counts of yeasts in analyzed samples were not detected. Counts of LAB at the end of ripening proccess (30 days were lower in coparison with result obtained after 5 days; however their count was comparable with count determined at the beginig of the ripening. Our results show, that the combination of starter culture and commercial spice mixture containig GdL may cause excesive sour taste and sensory defect of dry fermented meat products.

    2018-06-01

    In the present study, 18 plasticizers and residues in 10 different Tunisian and Italian culinary herbs and spices (black pepper, mint, caraway, coriander, oregano, rosemary, thyme, fennel, verbena, and laurel) were determined by GC/MS. Di-methylphthalate, di-(2-methylpropyl)adipate, di-n-butyladipate, di-propylphthalate, benzylbenzoate, di-phenylphthalate, and bisphenol A were lower than their LOQ in all 118 samples. Among the Tunisian samples, di-(2-ethylhexyl)phthalate was found in all types of samples and di-butylphthalate in 50% of types; all other phthalates were rarely dectected. Among the adipates, only di-methyladipate was found in 90% of types; di-ethyladipate was seldom found and di-(2-ethylhexyl)adipate only in samples of caraway. Di-(2-ethylhexyl)terephthalate was found in all types of samples; di-(2-ethylhexyl)sebacate was detected rarely but with high values. Among the Sicilian samples, di-ethylphthalate and di-(2-methylpropyl)phthalate were detected only in samples of mint; di-methyladipate, di-butylphthalate, and benzylbutylphthalate were identified in oregano and laurel; di-(2-ethylhexyl)terephthalate and di-(2-ethylhexyl)sebacate only in oregano. In any case, the results suggested that intake of these contaminants through spices and herbs is not a dangerous risk to the consumers. Probably, as already observed for the other food, these contaminants could result from pollution of the environment (air, water, and/or soil) and/or farming methods. Plasticizers and BPA in Tunisian and Italian spices were determined by GC/MS. Tunisian spices seem to contain more residues than Italian samples. Intake of these contaminants by spices is not a dangerous risk to the consumers. These pollutants could result from environmental pollution or agricultural practices. © 2018 Institute of Food Technologists®.

  1. Detection of Certain Spices Subjected to Gamma Irradiation By Using Thermal Analysis Technique

    Sayed, M.S.; Ali, H.G.M.; Abdeldaiem, M.H.

    2013-01-01

    The present investigation was carried out to apply a detection method of some irradiated spices using thermal analysis technique. Black pepper, cumin and ginger were irradiated using gamma irradiation at dose levels 5, 10 and 15 kGy and stored for 12 months at room temperature. Thermal analysis techniques TGA and DTA were studied for characterizing irradiated spices. Thermo gravimetric analysis (TGA) is a method where the measurement of mass as a function of heating is recorded. TGA was used to determine the moisture and ash contents and thermal stabilities. Non-significant changes of the weight loss percent due to the irradiation were occurred on the studied spices up to 10 kGy. The weight loss was decreased at the first step up to 100 degree C due to the release of water of hydration. Another sharp decreasing in weight loss percent at the second step 220-300 degree C may be due to volatilization of the sample. The final weight loss weight loss stage up to 500 degree C may be due to burn out the fixed carbon remaining in the sample. As the irradiation dose increased from control up to 15 kGy, the weight loss percent at the dehydration step was decreased. The kinetics of the spices decomposition were studied in order to ascertain the type of weight loss mechanism and calculate the activation energy (E a ). The differential thermal analysis (DTA) of the studied samples showed two main characteristic peaks; endothermic one due to the dehydration process and the second peak may be due to the partial volatilization of the aromatic compounds of the main constituent of the studied spices. It could be concluded that using gamma irradiation (up to 15.0 kGy) for black pepper, cumin and ginger are thermally stable to human consumption.

    Commercial spices represent an emerging class of fuels for improvised explosives. Being able to classify such spices not only by type but also by brand would represent an important step in developing methods to analytically investigate these explosive compositions. Therefore, a combined ambient mass spectrometric/chemometric approach was developed to quickly and accurately classify commercial spices by brand. Direct analysis in real time mass spectrometry (DART-MS) was used to generate mass spectra for samples of black pepper, cayenne pepper, and turmeric, along with four different brands of cinnamon, all dissolved in methanol. Unsupervised learning techniques showed that the cinnamon samples clustered according to brand. Then, we used supervised machine learning algorithms to build chemometric models with a known training set and classified the brands of an unknown testing set of cinnamon samples. Ten independent runs of five-fold cross-validation showed that the training set error for the best-performing models (i.e., the linear discriminant and neural network models) was lower than 2%. The false-positive percentages for these models were 3% or lower, and the false-negative percentages were lower than 10%. In particular, the linear discriminant model perfectly classified the testing set with 0% error. Repeated iterations of training and testing gave similar results, demonstrating the reproducibility of these models. Chemometric models were able to classify the DART mass spectra of commercial cinnamon samples according to brand, with high specificity and low classification error. This method could easily be generalized to other classes of spices, and it could be applied to authenticating questioned commercial samples of spices or to examining evidence from improvised explosives.

    Spices and herbs have been used in food since ancient times to give taste and flavor and also as food preservatives and disease remedies. In Cameroon, the use of spices and other aromatic plants as food flavoring is an integral part of dietary behavior, but relatively little is known about their antifungal potential.The present work was designed to assess the antifungal properties of extracts from spices used in Cameroonian dietary. The in vitro antifungal activities of twenty three extracts from twenty one spices were assessed by the broth micro-dilution method against eight fungi. Also, the in vivo activity of Olax subscorpioidea extract (the most active extract) was evaluated in rat model of disseminated candidiasis due to Candida albicans by estimating the fungal burden in blood and kidney. Seven extracts (30%) exhibited moderate to significant antifungal activities, inhibiting the growth of the microorganisms at concentrations ranging from 0.048 to 0.39 mg/mL. Olax subscorpioidea extract exhibited the highest antifungal activity particularly against Candida albicans and Candida tropicalis (MIC of 0.097 mg/mL and 0.048 mg/mL respectively). Sixteen extracts (70%) were weakly active (MICs > 6.25 mg/mL). Oral administration of O. subscorpioidea extract at the dose 2 g/kg of body weight (bw) to artificially infected rats revealed a drop in the number of colony forming units per milliliter (cfu/mL) of Candida albicans cells in the blood below the detection limit (100 cfu/mL) while a modest decrease was observed in the kidney. The present work shows that some of the spices studied possess interesting antifungal properties and could be used to treat candidiasis. Among the plant species tested, Olax subscorpioidea displayed the most promising result.

    The study of fungal contamination in food and mycotoxicoses is a priority today, both internationally and nationally. The purpose of this study is to have a general view over the quality of the most common spices that are sold in Romanian markets, by assessing the degree of fungal, bacterial and mycotoxin contamination in pepper and chili powders. We tested four types of spices: white pepper, black pepper, sweet and hot chili powders from 12 different distributing companies, summing a total of 35 sample types. The fungal and bacterial load was assessed by Standard Plate Count, while the mycotoxin content by High-performance liquid chromatography. Environmental conditions (humidity, pH) and the selling price for each product were also followed. Fungi were observed in 72.7% of black pepper samples, 33.3% in white pepper, 30% in sweet chili and 25% in hot chili products. The most common isolated fungus was Aspergillus spp., while Rhizopus, Mucor, Fusarium, Penicillium, Absidia species were found, in smaller percentage. Four producers (44.4%) presented fungal contamination of over 10^3 CFU/g and two producers (22.2%) presented no fungal contamination in their products. Bacterial contamination was found in 85.7% of the tested products, consisting mostly in Bacillus spp. Aflatoxin B1 was present in all the tested products, mostly in black pepper (mean value 126.3 ng/g); Ochratoxin A was present in sweet chili (mean value 328 ng/g) and Zearalenone in hot chili (mean value 604 ng/g) and sweet chili (mean value 382 ng/g). All spices presented either fungal contamination, mycotoxin contamination, or both. The high humidity and the high pH of spices represent favorable conditions for fungal growth. The selling price was partly related to the physic-chemical conditions and microbiological quality of the spices.

  5. Identification of dehydrated spices and herbs subjected to the irradiation process

    Bernardes, Dulcila Maria Lessa

    1996-01-01

    This research shows the possibility of determining through a combination of analytical methods whether dehydrated spices and herbs were irradiated. The methods used were the following: viscosimetry, thermoluminescence (TL) and electron paramagnetic resonance (EPR). Viscosimetry was applied in suspensions of dehydrated and irradiated spices and herbs which had been gellified by heat. It was observed that the viscosity of the samples decreases when the radiation dose increases. It was also observed that the temperature of the gelification is linked to the viscosity. The variation of the capability of gelification of the samples in relation to the storage time (30 and 60 days) does not have any consequence on the viscosity. Thermoluminescence is based on the transference of electrons to an excited state by ionizing radiation with emission of light when the electrons thermally stimulated. The thermoluminescent signals of the spices can be explained by the presence of mineral grains adhering to the surface of the samples. The thermoluminescent signal increased in intensity with the amplification of the radiation dose. The study of the signal in relation to the storage time (30 and 60 days) showed that it weakened and decreased. Free radicals produced by irradiation of spices were analyzed by the electron spin resonance method (ESR). It was checked that increasing the radiation dose meant an intensification of the ESR signal. Within a 30 day storage time, a fading of the signal was observed. The results of this study lead us to the following conclusion: viscosimetry, thermoluminescence and electron spin resonance are methods of analysis which are proper to detect whether dehydrated spices and herbs were irradiated, especially when these different methods were used in combination.

    2012-01-01

    The authors analyze the Mexican energy policy taking as reference the methodological framework for sustainable energy development proposed by the Economic Commission for Latin America and the Caribbean. This methodology takes eight related indicators to the social, environmental and economic dimensions in order to calculate a general sustainability indicator for the energy sector. In this methodology, the weight of each dimension is different; namely, the social and environmental issues have less relevance than the economic issues. The authors use this methodology because government institutions as the Department of Energy and the Department of Environment and Natural Resources have used some indicators from such a methodology to propose plans, programs, projects and bills. Authors know of the existence of other methodologies about sustainability. Nonetheless, opting for the Economic Commission for Latin America and the Caribbean's methodology is convenient because this organization is a respectable authority for civil servants from the Mexican institutions. Our objective is just to contrast the sustainability grade of the energy sector between 1990 and 2008 for Mexico whose government started reforms in the 1990s. It concludes that those reforms did not bring about a higher sustainability level for the energy sector. - Highlights: ► We used the OLADE, CEPAL and GTZ's methodology to calculate sustainability indicators for the Mexican energy sector. ► We studied the Mexican energy policy from 1990 to date and presented it. ► Currently, the Mexican energy sector is less sustainable than in 1990.

    2012-01-01

    Full Text Available El Sistema para la Autonomía y Atención a la Dependencia (SAAD fue creado con el fin de proporcionar un marco de protección a las personas en situación de dependencia. La prioridad de las prestaciones en servicios frente a las económicas, según la Ley, y la gestión eficiente de los recursos públicos destinados al SAAD hacían prever retornos económicos, como la generación de empleo. Las variables que influyen en la implantación del SAAD son extremadamente complejas y dinámicas, existiendo múltiples relaciones entre las mismas. El objetivo de este trabajo es analizar la problemática de satisfacer una demanda creciente de protección al mínimo coste y aprovechar los retornos económicos mediante la lógica borrosa (mapa cognitivo borroso. Esta técnica se configura como una herramienta para la toma de decisiones en este ámbito, porque permite analizar la evolución de las variables causales hasta un estado de equilibrio. Para ello, se han ideado 4 escenarios (E1:Envejecimiento, E2: Envejecimiento y prestaciones en servicios, E3: Envejecimiento y prestaciones económicas, E4: Envejecimiento y prestación económica para cuidados en el entorno familiar, con el fin de analizar la evolución de las variables, especialmente el gasto público y el empleo. Entre los principales resultados obtenidos destacan: el envejecimiento es determinante en el incremento del gasto en todos los escenarios, pero solamente en E1 y E2 se genera empleo. La prestación residencial no se altera, ni siquiera en E2. La teleasistencia aumenta en todos los escenarios y la prestación económica por asistente personal aumenta en E1 y E2.

    Ghalachyan, L.M.; Kocharyan, K.A.; Aristakesyan, A.A.; Asatryan, A.Z.

    2015-01-01

    Peculiarities of some heavy metals (HM), (Mn, Ni, Ti, V, Co, Cu, Pb, Mo, Cr, Zr) accumulation have been studied in spice herbs (basil, dill, coriander, savory) grown in open-air hydroponics and soil cultures of the Ararat Valley. It turned out that the amount of HM content in spice herbs grown in open-air hydroponic conditions was less than in the ones grown in soil conditions. The content of Pb and Ni in spice herbs exceeded the allowed concentration limits (ACL), especially in soil plants. Practical recommendations on obtaining ecologically safe agricultural products have been prepared. The biotechnological hydroponics method of producing spice herbs in the Ararat Valley is ecologically more beneficial than the soil method. Practical proposals of obtaining ecologically safe agricultural products have been developed

  16. Craniofacial Secular Change in Recent Mexican Migrants.

    Spradley, Katherine; Stull, Kyra E; Hefner, Joseph T

    2016-01-01

    Research by economists suggests that recent Mexican migrants are better educated and have higher socioeconomic status (SES) than previous migrants. Because factors associated with higher SES and improved education can lead to positive secular changes in overall body form, secular changes in the craniofacial complex were analyzed within a recent migrant group from Mexico. The Mexican group represents individuals in the act of migration, not yet influenced by the American environment, and thus can serve as a starting point for future studies of secular change in this population group. The excavation of a historic Hispanic cemetery in Tucson, Arizona, also allows for a comparison between historic Hispanics and recent migrants to explore craniofacial trends over a broad time period, as both groups originate from Mexico. The present research addresses two main questions: (1) Are cranial secular changes evident in recent Mexican migrants? (2) Are historic Hispanics and recent Mexican migrants similar? By studying secular changes within a migrant population group, secular trends may be detected, which will be important for understanding the biological variation of the migrants themselves and will serve as a preliminary investigation of secular change within Mexican migrants. The comparison of a sample of recent Mexican migrants with a historic Hispanic sample, predominantly of Mexican origin, allows us to explore morphological similarities and differences between early and recent Mexicans within the United States. Vault and face size and a total of 82 craniofacial interlandmark distances were used to explore secular changes within the recent Mexican migrants (females, n = 38; males, n = 178) and to explore the morphological similarities between historic Hispanics (females, n = 54; males, n = 58) and recent migrants. Sexes were separated, and multivariate adaptive regression splines and basis splines (quadratic with one knot) were used to assess the direction and magnitude

  20. Nervios and dysphoria in Mexican American widows.

    Kay, M; Portillo, C

    1989-01-01

    One hundred widows participating in experimental research entitled Efficacy of Support Groups for Mexican American Widows were studied to learn how they express the loss of their husbands. Mourning practices, acknowledged symptoms of dysphoria, and somatic reactions were studied to learn if the syndrome of nervios subsumes their reaction to bereavement. In addition, their responses to instruments designed to measure depression, the Spanish version of the Beck Depression Inventory and the Center for Epidemiologic Studies Depression Scale, were examined for correlation with nervios and relationships to Mexican American acculturation. Nervios seems to be a manifestation of dysphoria rather than a specific syndrome for these women.
