    Full Text Available One of the main process industries in Cuba is that of the sugarcane. Among the characteristics of this industry is the high demand of water in its processes. In this work a study of water integration was carried out from the different operations of the production process of raw sugar, in order to reduce the fresh water consumption. The compound curves of sources and demands were built, which allowed the determination of the minimum water requirement of the network (1587,84 m3/d, as well as the amount of effluent generated (0,35 m3/tcane.The distribution scheme of fresh water and water reuse among different operations were obtained from the nearest neighbor algorithm. From considering new quality constrains was possible to eliminate the external water consumption, as well as to reduce the amount of effluent in a 37% in relation to the initial constrains.

  14. Tracing and control of raw materials sourcing for vaccine manufacturers.

    Science.gov (United States)

    Faretra Peysson, Laurence

    2010-05-01

    The control of the raw materials used to manufacture vaccines is mandatory; therefore, a very clear process must be in place to guarantee that raw materials are traced. Those who make products or supplies used in vaccine manufacture (suppliers of culture media, diagnostic tests, etc.) must apply quality systems proving that they adhere to certain standards. ISO certification, Good Manufacturing Practices for production sites and the registration of culture media with a 'Certificate of Suitability' from the European Directorate for the Quality of Medicines and Healthcare are reliable quality systems pertaining to vaccine production. Suppliers must assure that each lot of raw materials used in a product that will be used in vaccine manufacture adheres to the level of safety and traceability required. Incoming materials must be controlled in a single 'Enterprise Resource Planning' system which is used to document important information, such as the assignment of lot number, expiration date, etc. Ingredients for culture media in particular must conform to certain specifications. The specifications that need to be checked vary according to the ingredient, based on the level of risk. The way a raw material is produced is also important, and any aspect relative to cross-contamination, such as the sanitary measures used in producing and storing the raw material must be checked as well. In addition, suppliers can reduce the risk of viral contamination of raw materials by avoiding purchases in countries where a relevant outbreak is currently declared. 2010 The International Association for Biologicals.

  15. Raw materials in the manufacture of biotechnology products: regulatory considerations.

    Science.gov (United States)

    Cordoba-Rodriguez, Ruth

    2010-01-01

    The Food and Drug Administration's Pharmaceutical cGMPs for the 21st Century initiative emphasizes science and risk-based approaches in the manufacture of drugs. These approaches are reflected in the International Conference on Harmonization (ICH) guidances ICH Q8, Q9, and Q10 and encourage a comprehensive assessment of the manufacture of a biologic, including all aspects of manufacture that have the potential to affect the finished drug product. Appropriate assessment and management of raw materials are an important part of this initiative. Ideally, a raw materials program should strive to assess and minimize the risk to product quality. With this in mind, risk-assessment concepts and control strategies will be discussed and illustrated by examples, with an emphasis on the impact of raw materials on cell substrates. Finally, the life cycle of the raw material will be considered, including its potential to affect the drug product life cycle. In this framework, the supply chain and the vendor-manufacturer relationship will be explored as important parts of an adequate raw materials control strategy.

    In SugarTech project, spruce, forest residue, birch and sugar cane bagasse have been studied as a raw material for production of sugars to be processed further to ethanol and other chemicals. These raw materials containing high proportion of carbohydrates have been analysed and pretreated for enzyme hydrolysis by steam explosion and oxidative methods. The pretreated materials have been studied in respect to yield and enzymatic hydrolysability. Birch and bagasse could easily be pretreated with steam explosion. Catalytic oxidation treatment of spruce produced material with superior hydrolysability to steam exploded material. Enzyme adsorption and desorption were studied aiming at recycling of enzymes in the hydrolysis process. Purified cellulase enzymes were found to have high tendency to adsorption on lignocellulosic substrate. Adsorption could be decreased by additives, e.g. urea and BSA. In addition, the hydrolytic system of Trichoderma reesei in the presence of different substrates has been studied. (orig.)

    In the SugarTech project, spruce, forest residue, birch and sugar cane bagasse have been studied as raw materials for production of sugars to be processed further to ethanol or other chemicals. These raw materials, containing high proportion of carbohydrates have been analysed and pretreated for enzymatic hydrolysis by steam explosion and oxidative methods. The pretreated materials have been studied in respect to yield and enzymatic hydrolysability. Small carboxylic acids were an interesting side product from oxidation pretreatment. For feasibility study, 8 process cases have been selected and will be compared. Optimal enzyme mixtures have been determined for hydrolysis of pretreated materials. Results show that optimal enzyme composition depends clearly on the raw material and the pretreatment method. Pretreated raw materials were also hydrolysed efficiently in high dry matter conditions with commercial enzymes. Enzyme adsorption and desorption were studied with lignocellulosic substrates aiming at recycling of enzymes in the hydrolysis process. After enzymatic hydrolysis, a major part of the enzymes remained bound to substrate in spite of high degree of hydrolysis. Desorption of enzymes could only be detected with catalytically oxidised spruce. In addition, the induction of hydrolytic system of Trichoderma reesei, which is a widely used fungus for cellulase enzyme production, has been studied in the presence of different substrates. The substrate and the pretreatment method had clear effects on gene expression profile. (orig.)

  5. USED IN THE MANUFACTURE OF EMULSION RUBBER WASTE OF SUGAR MANUFACTURE – MOLASSES

    Directory of Open Access Journals (Sweden)

    S. S. Nikulin

    2015-01-01

    Full Text Available Currently, much attention is paid to development, allowing use of waste and by-products formed during certain manufacturing processes. This allows you to either reduce or completely eliminate the use of valuable and expensive raw materials. The use of this raw material in the production of synthetic rubber will not only reduce the cost of coagulation and acidifying agents, but also to improve the environmental situation. Featured in some cases effective coalescing agents based on polymeric quaternary ammonium salts (PCHSA have a high coagulating power, and hence low consumption of the allocation of the rubber latex (3-5 kg0t-1 rubber. Scarcity and high cost of these drugs leads to higher prices resulting rubber. Furthermore it is known that the application requires keeping PCHSA sufficiently precise dosage administered substances by the action of a latex, owing to the high capacity of the antiseptic may lead to discharge into natural waters polluted waters. However, using as the coagulating agent departing sugar production molasses solves a number of problematic steps in the production of synthetic rubber. First, a well-studied effective coagulation effect of different nitrogen derivatives relating to cationic surfactants. In freshly prepared solutions of molasses contained about 9 wt%, and this value increases significantly during enzymatic fermentation. Secondly, highly acidic environment of aqueous solutions of molasses after storage can allow their use in addition to or instead of the sulfuric acid used in large amounts (up to 15 kg m-1 rubber technology selection tests carried found that vulcanizates derived from rubber samples isolated molasses, consistent with the requirements and were similar to control samples prepared from the latex using sodium chloride.

  6. Chemistry Based on Renewable Raw Materials: Perspectives for a Sugar Cane-Based Biorefinery

    Directory of Open Access Journals (Sweden)

    Murillo Villela Filho

    2011-01-01

    Full Text Available Carbohydrates are nowadays a very competitive feedstock for the chemical industry because their availability is compatible with world-scale chemical production and their price, based on the carbon content, is comparable to that of petrochemicals. At the same time, demand is rising for biobased products. Brazilian sugar cane is a competitive feedstock source that is opening the door to a wide range of bio-based products. This essay begins with the importance of the feedstock for the chemical industry and discusses developments in sugar cane processing that lead to low cost feedstocks. Thus, sugar cane enables a new chemical industry, as it delivers a competitive raw material and a source of energy. As a result, sugar mills are being transformed into sustainable biorefineries that fully exploit the potential of sugar cane.

    The objective of this study was to examine the extractive, holocellulose, alpha cellulose, lignin, starch, and sugar contents of oil palm biomass and to evaluate its suitability in binderless particleboard production. In this study, bark, leaves, fronds, mid-parts and core-parts of the trunks were used to produce experimental binderless particleboard panels. Binderless particleboard panels were made with a target density of 0.80 g/cm 3 at a temperature of 180 o C and a pressure of 12 MPa in a computer controlled hot press. The modulus of rupture, the internal bond strength, the thickness swelling and the water absorption of the panels were evaluated. Fourier transform infrared spectroscopy and field emission scanning electron microscopy were used to characterize the properties of the raw materials and the manufactured panels. The chemical composition of the oil palm biomass consisted of high holocellulose, lignin, starch and sugar contents that have been found to aid in the production of binderless particleboard. The core-part of the trunk contained the highest amount of starch and total sugar. Samples made from the core-parts and fronds had sufficient modulus of rupture and internal bond strength to meet the Japanese Industrial Standard. The internal bond strength of the mid-part panels also met the standard. However, binderless board prepared from bark and leaves showed poor modulus of rupture and internal bond strength. Samples from the core-parts had the lowest thickness swell and water absorption but did not meet the above standard. The Fourier transform infrared spectroscopy spectra did not show any substantial difference between the raw materials and the manufactured panels. Field emission scanning electron microscopy indicated that the compressed cells varied between raw material types and showed the presence of compressed cells with some starch granules that facilitated adhesion. Based on the findings of this study, oil palm has the potential to be used to

  11. Sweet sorghum: A new raw material source for the sugar industry

    Energy Technology Data Exchange (ETDEWEB)

    El Bassam, N; Dambroth, M; Ruehl, G

    1987-01-01

    The primary uses of sweet sorghum have been as a syrup for human consumption and as a livestock feed. More recently, interest in sweet sorghum has risen because of its potential use as a source of sugar and/or as a raw material for the production of energy and for different biotechnological processes. However, before sweet sorghums may be utilized as a source for both sugar and energy, adequate and adapted genotypes must be identified. The objective of this study is to measure the agronomic performance of different lines and cultivars of sweet sorghum for cold tolerance yield of biomasse, yield of sugar and sugar quality. Of the more than 1000 entries from 20 different world-wide origins, 614 accessions have been cultivated for evaluation purposes in the last 2 years. Among the tested material 18 genotypes exhibited more than 90 tons biomass (FM) per hectare in 1985 and 32 types in 1986. The number of accessions which produced more than 90 th FM/ha in both years was 10, one type produced more than 11 tons FM/ha. The biomasse production of one accession achieved 169 t FM/ha in 1986. The highest sugar content in FM mounted to 9,2% in 1985 and 11,1% in 1986. Five genotypes produced more than 10 tons sugar per hectare, the highest sugar yield was 12 t/ha. In average of the high sugar yielding accessions, more than 50% of the sugar consists of saccharose, 28% of glucose and 19% of fructose. The corresponding quantity of alcohol which can be produced amounts to 7 000 l/ha. (orig.)

  12. Raw materials evaluation and process development studies for conversion of biomass to sugars and ethanol

    Energy Technology Data Exchange (ETDEWEB)

    Wilke, C.R.; Yang, R.D.; Sciamanna, A.S.; Freitas, R.P.

    1978-06-01

    A range of cellulosic raw materials in the form of agricultural crop residue was analyzed for chemical composition and assessed for potential yields of sugars through chemical pretreatment and enzymatic hydrolysis of these materials. Corn stover was used as a representative raw material for a preliminary process design and economic assessment of the production of sugars and ethanol. With the process as presently developed, 23 gallons of ethanol can be obtained per ton of corn stover at a processing cost of about $1.80 per gallon exclusive of by-product credits. The analysis shows the cost of ethanol to be highly dependent upon (1) the cost of the biomass, (2) the extent of conversion to glucose, (3) enzyme recovery and production cost and (4) potential utilization of xylose. Significant cost reduction appears possible through further research in these directions.

    2010-01-01

    Full Text Available Response surface methodology (RSM was used for selecting optimal fermentation time and initial sugar mass fraction in cultivation media based on raw juice from sugar beet in order to produce ethanol. Optimal fermentation time and initial sugar mass fraction for ethanol production in batch fermentation by free Saccharomyces cerevisiae cells under anaerobic conditions at the temperature of 30 °C and agitation rate of 200 rpm were estimated to be 38 h and 12.30 % by mass, respectively. For selecting optimal conditions for industrial application, further techno-economic analysis should be performed by using the obtained mathematical representation of the process (second degree polynomial model. The overall fermentation productivity of five different types of yeast was examined and there is no significant statistical difference between them.

    The aim of this paper was to analyze the sugar cane bagasse ash from three Sugar and Alcohol Plant of the State of Sao Paulo - Brazil. We intend to show the discrepancies between them, so that this raw material could be used with greater quality control in ceramic industries. The bagasse were analyzed by differential scanning calorimetry (DSC), thermogravimetry (TG) and scanning electron microscopy. The ashes were analyzed by X-ray diffraction, X-ray fluorescence, scanning electron microscopy, energy dispersive spectroscopy, and granulometric separation. The results indicated that the content of SiO 2 ranging from 50-80% by weight depends on the granulometry of the bagasse and on the region where it was collected. The analyses of X-ray diffraction indicate SiO 2 , Fe 2 O 3 , K 2 SO 4 and Mg 2 P 2 O 7 as crystalline phases. (author)

    New Caledonian crows use a range of foraging tools, and are the only non-human species known to craft hooks. Based on a small number of observations, their manufacture of hooked stick tools has previously been described as a complex, multi-stage process. Tool behaviour is shaped by genetic predispositions, individual and social learning, and/or ecological influences, but disentangling the relative contributions of these factors remains a major research challenge. The properties of raw materials are an obvious, but largely overlooked, source of variation in tool-manufacture behaviour. We conducted experiments with wild-caught New Caledonian crows, to assess variation in their hooked stick tool making, and to investigate how raw-material properties affect the manufacture process. In Experiment 1, we showed that New Caledonian crows' manufacture of hooked stick tools can be much more variable than previously thought (85 tools by 18 subjects), and can involve two newly-discovered behaviours: 'pulling' for detaching stems and bending of the tool shaft. Crows' tool manufactures varied significantly: in the number of different action types employed; in the time spent processing the hook and bending the tool shaft; and in the structure of processing sequences. In Experiment 2, we examined the interaction of crows with raw materials of different properties, using a novel paradigm that enabled us to determine subjects' rank-ordered preferences (42 tools by 7 subjects). Plant properties influenced: the order in which crows selected stems; whether a hooked tool was manufactured; the time required to release a basic tool; and, possibly, the release technique, the number of behavioural actions, and aspects of processing behaviour. Results from Experiment 2 suggested that at least part of the natural behavioural variation observed in Experiment 1 is due to the effect of raw-material properties. Our discovery of novel manufacture behaviours indicates a plausible scenario for the

    The batch fermentation process of sugar beet processing intermediates by free yeast cells is the most widely used method in the Autonomous Province of Vojvodina for producing ethanol as fuel. In this study a process and cost model was developed for producing ethanol from raw juice. The model can be used to calculate capital investment costs, unit production costs and operating costs for a plant producing 44 million l of 99.6% pure ethanol annually. In the sensitivity analysis the influence of sugar beet and yeast price, as well as the influence of recycled biomass on process economics, ethanol production costs and project feasibility was examined. The results of this study clearly demonstrate that the raw material costs have a significant influence on the expenses for producing ethanol. Also, the optimal percentage of recycled biomass turned out to be in the range from 50% to 70%. Copyright © 2011 Elsevier Ltd. All rights reserved.

    The industrial conditions for the combined use of these raw materials varies considerably from those for separate application. Calculation formulas are developed, and example calculations are shown, for yields, purity coefficient, conversion values after saccharification of potato and grain starches, and mash concentrations prior to mixing with molasses mash for optimum yields. Of high importance is the acidity adjustment prior to fermentation. The molasses mash joining the saccharified starch mash is so adjusted as to produce a final mixture of pH 5.3 to 5.6, and to titrate with saccharified grain starch 0.25 to 0.3/sup 0/ acidity, and with potato starch 0.3 to 0.4/sup 0/. The reduction of molasses alkalinity by 1/sup 0/ (1/sup 0/ alkalinity corresponds during titration to 1 cc. of N H/sub 2/SO/sub 4/ in 100 g. molasses) for 1 ton requires 270 cc. H/sub 2/SO/sub 4/ (monohydrate) or 770 cc. HCl (sp. gr. 1.19). For acidifying 1 m./sup 3/ molasses mash by 0.1/sup 0/, 140 cc. H/sub 2/SO/sub 4/ or 400 cc. HCl are needed. Molasses are diluted and sterilized at 85 to 90/sup 0/ for 30 to 45 minutes, cooled down, and adjusted with cold water to the required sugar content. Yeast is added to provide a concentration of 80 to 90 million/cc. in grain- or potato-starch mash prior to admixture of molasses mash; it reaches 130 to 140 million cc. after completion of admixture. The molasses mash is added after the starch mash has fermented down to 10 to 11% and the addition takes 8 to 10 hours for a total fermentation time of 48 hours.

    About 6 to 7 million tons of sugar cane leaves are available per year as agricultural residue and can be utilized for manufacture of cheap grades of paper and board. An unbleached yield of 56% could be obtained using 10% NaOH at a temperature of 170/sup 0/C with a bath ratio of 1 to 4 and cooking time of 10 min. Sulfate pulping with equivalent conditions gave a bleached pulp with comparatively higher brightness values, other properties remaining almost same. Bleaching of 10% soda pulp with 10 and 12% chlorine have given 42 and 40% yields at 71 to 72 and 77 to 78% Elrepho brightness, respectively. In case of 9% sulfate pulp the yields are 36 to 37% at 77 to 79% brightness when bleached with the same sequence as above with 10 to 10.5% chlorine. The pulps are strong for preparation of cheap grades of bleached as well as unbleached varieties of paper. Double fold and tear are however medium to low and hence need long fibered pulp blending to improve these characteristics.

    Full Text Available The substantiation for using techniques of fish raw material canning has been presented, raw fish being caught or farmed in aquaculture. The main problems in raw fish canning have been reviewed, including significant reduction in thermolabile vitamins in the ultimate product as compared with the raw material due to the thermal processing. Promising canning technique – vacuum drying – has been proposed. This technique makes possible to reduce the temperature of thermal processing down to 50…55 °С and significantly enlarge preservation of thermolabile vitamins from the raw fish. Sampling of raw materials, semi-finished products, finished products, including preparation for analysis has been conducted by standard methods. Disadvantages of this way have been found, it is low energy efficiency of the process. The way to intensify the vacuum drying of aquatic organisms has been proposed based on the method of preliminary pore-forming due to augmenting the area of moisture evaporation. The design of the pilot plant has been proposed in order to research the process of pore forming and vacuum drying. Target species for processing have been suggested. They are as follows: Azov goby (fillet for food products and Black Sea sprat for feeds. The recipes of the feed mixture for granulated floating food for trout have been developed. The results of the first series of the pilot research have been provided. The experiments have proved that preliminary pore forming immediately before vacuum drying makes possible to enlarge the surface area of moisture evaporation by 15…25 %. By processing photomicrographs of sections by means of a special software the authors have got the results demonstrating that when manufacturing dried products by pore forming and drying under pressure 10 kPa the pore take 35...38 % of the inner volume of the product and with drying under pressure 10 kPa – only 18...21 %, and when drying under the atmospheric pressure – 11...13 %.

  5. Lime kiln dust as a potential raw material in portland cement manufacturing

    Miller, M. Michael; Callaghan, Robert M.

    2004-01-01

    In the United States, the manufacture of portland cement involves burning in a rotary kiln a finely ground proportional mix of raw materials. The raw material mix provides the required chemical combination of calcium, silicon, aluminum, iron, and small amounts of other ingredients. The majority of calcium is supplied in the form of calcium carbonate usually from limestone. Other sources including waste materials or byproducts from other industries can be used to supply calcium (or lime, CaO), provided they have sufficiently high CaO content, have low magnesia content (less than 5 percent), and are competitive with limestone in terms of cost and adequacy of supply. In the United States, the lime industry produces large amounts of lime kiln dust (LKD), which is collected by dust control systems. This LKD may be a supplemental source of calcium for cement plants, if the lime and cement plants are located near enough to each other to make the arrangement economical.

  6. Energy consumption for sugar manufacturing. Part I: Evaporation versus reverse osmosis

    Removing water from various feeds is usually carried out using evaporation process especially in food industry. Due to the high latent heat of water, this unit operation results in consumption of unacceptable amount of energy. Finding low energy consuming processes which could be replaced with this process is still a challenge. The processes with no phase inversion may be considered for concentration purposes with reasonable energy consumption in comparison with the other various separation procedures. Reverse osmosis and most of the other membrane technologies are separation techniques without any change in the phase and therefore consume low amount of energy. Concentrating the sugar thin juice in the classical sugar manufacturing procedure is carried out using conventional evaporation. Reverse osmosis membranes may be used as a pre-concentration step to partially separate water from the sugar thin juice in combination with this part of the plant. Final concentration and thick juice preparation for crystallization may be carried out in the evaporation unit. In this study, membranes were employed for sugar thin juice concentration using a two-stage reverse osmosis process in two different arrangements. The energy consumption was calculated and compared for conventional evaporation versus reverse osmosis combined with evaporation. The results indicate that the employment of reverse osmosis membranes for concentrating the sugar thin juice leads to sensibly lower energy requirements. Furthermore, there is no thermal loss of sugar in the membrane process.

    Traditional Indian Dairy Products are manufactured in India using an age old practice which varies from place to place. For manufacture of these products industrially, a standard formulation is required. Thabdi, a region specific, very popular heat desiccated milk product is one of such products which has not been studied scientifically. Sugar plays an important role in physico-chemical, sensory, textural characteristics and also the shelf life of any milk sweet. Hence for process standardization of Thabdi manufacture, different levels of sugar i.e. 4, 6, 8 and 10 (percent of milk) were studied so that an optimum level yielding best organoleptic characteristics in final product can be selected. The product was made from milk standardized to 0.66 Fat:SNF level and added with ghee @ 1.2 % of milk at the time of colour and texture development stage as selected from the earlier phase of study. Based on the results obtained, a level of 8 % sugar addition on the milk basis at the time of manufacture has been selected to have full taste and sensory attributes.

    2016-12-01

    Full Text Available Levulinic acid (LA is one of the top bio-based platform molecules that can be converted into many valuable chemicals. It can be produced by acid catalysis from renewable resources, such as sugars, lignocellulosic biomass and waste materials, attractive candidates due to their abundance and environmentally benign nature. The LA transition from niche product to mass-produced chemical, however, requires its production from sustainable biomass feedstocks at low costs, adopting environment-friendly techniques. This review is an up-to-date discussion of the literature on the several catalytic systems that have been developed to produce LA from the different substrates. Special attention has been paid to the recent advancements on starting materials, moving from simple sugars to raw and waste biomasses. This aspect is of paramount importance from a sustainability point of view, transforming wastes needing to be disposed into starting materials for value-added products. This review also discusses the strategies to exploit the solid residues always obtained in the LA production processes, in order to attain a circular economy approach.

    Oxidative stress modulates the osteoclast differentiation via redox systems, and thioredoxin 1 (Trx) promotes the osteoclast formation by regulating the activity of transcription factors. The function of Trx is known to be regulated by its binding partner, thioredoxin-interacting protein (TXNIP). We previously reported that the expression of TXNIP gene is strongly induced by a rare sugar D-allose. In this study, we tested the hypothesis that D-allose could inhibit the osteoclast differentiation by regulating the Trx function. We used a murine Raw264 cell line that differentiates to the osteoclast by the receptor activator of nuclear factor-κB ligand (RANKL) treatment. The effect of sugars was evaluated by tartrate-resistant acid phosphatase staining. The expression and localization of TXNIP and Trx protein were examined by Western blotting and immunohistochemisty. The activity of the nuclear factor-κB, nuclear factor of activated T cells, and activator protein 1 transcription factors was measured by the luciferase reporter assay. The addition of D-allose (25 mmol/L) inhibited the osteoclast differentiation down to 9.53% ± 1.27% of a receptor activator of nuclear factor-κB ligand-only treatment. During the osteoclast differentiation, a significant increase of TNXIP was observed by D-allose treatment. The immunohistochemical analysis showed that both Trx and TXNIP existed in the nucleus in preosteoclasts and osteoclasts. Overexpression of TXNIP by plasmid transfection also inhibited the osteoclast formation, indicating the functional importance of TXNIP for the osteoclast differentiation. Transcriptional activity of the activator protein 1, nuclear factor-κB, and nuclear factor of activated T cells, known to be modulated by Trx, were inhibited by D-allose. In conclusion, our data indicate that D-allose is a strong inhibitor of the osteoclast differentiation, and this effect could be caused by TXNIP induction and a resulting inhibition of the Trx function

    The nuclear fuel for Cernavoda Romanian nuclear power plant is based on natural uranium cycle implying mining, concentration-refining and UO 2 manufacturing. For the Uranium National Company securing the raw materials necessary for fuel element manufacturing implies the following sources: - from the production cumulated till the year 2001 in the Security and Consumption Stock; - from the current production of uranium ore. Romania posses two categories of deposits which ensure at present and in the future the uranium ore production: active deposits and production center at Crucea-Botusana; - deposits proposed for the exploitation activity at Tulghes - Grinties. Other two important centers of production in Banat and Bihor ceased the production since 1999 due to the deposit depletion. The uranium reserve of Romania is estimated to 9,233 tones in geological deposits of high confidence level plus 6,344 tones in resources still not searched. The medium- and long-term strategy of CNU to fructify the uranium reserves of Romania is in concordance with the current government policy and is based upon two major investments: - opening a new production unit at Tulghes-Grinties; - Refurbishment of plants R1 and E1. The main amount of uranium currently used for making the needed nuclear fuel comes today from the production center Crucea-Botusana. Here the exploitation is based mainly on pitchblende-rich deposits. Uranium ore processing and concentration is made at 'R' and 'E' plants at Feldioara able to ensure an annual capacity of 300 tones UO 2 . In the assesment of the amount of uranium needed in the nuclear fuel fabrication the degree of uranium recovery was also taken into account. The uranium supply implied by the new electro-nuclear plants to be installed till 2025 was evaluated by taking into account the future advanced fuel solutions, SEU and RU, what will diminish the natural uranium consumption to 55% and 66%, respectively. The price of nuclear fuel has been estimated

    Full Text Available The presence and/or accumulation of mycotoxins in foods intended for human and animal nutrition is a constant concern for the harmful health effects resulting from ingestion. The aims of this communication were to analyze samples of feed and raw materials for manufacturing and to determine the presence of strains of filamentous fungi with toxigenic capacity. The values of frequency in the total samples (N = 422, indicated 63% of contamination, where A. flavus represented the most common (29.8%, while in feed and raw materials separately, indicated A. flavus has the highest value in both categories. In the analysis of different type of raw materials, A. flavus contaminated all types of samples, with the bran and soybean meal substrates having higher values for this Aspergillus, and corn substrate more fungal contamination. These results would demonstrate that the presence of mycobiota with toxigenic potential in food for animal feed is a disturbing reality.

    Tuberculosis (TB) remains one of the leading causes of morbidity and mortality among indigenous peoples in Brazil, and identifying the risk factors for TB in this population secondary to specific epidemiological conditions is essential for recommending interventions aimed at disease control. This case-control study was conducted with an indigenous population between June 2009 and August 2011 in Dourados, Brazil. Tuberculosis cases reported to the national disease surveillance programme were paired with two control cases matched by age and geographic location. There were 63 cases included in this study, and the annual incidence of TB in the indigenous communities examined was 222 (95% CI, 148-321) per 100 000 inhabitants. The multivariate analysis demonstrated that the variables associated with TB infection included male gender (OR 2.6; 95% CI 1.3-5.3), not owning a home (OR 3.4; 95% CI 1.2-10.1), illiteracy (OR 2.4; 95% CI 1.1-5.0), TB contact (OR 2.4; 95% CI 1.2-4.8) and work performed in a sugar cane factory (OR 6.8; 95% CI 1.2-36.9). There is a potential relationship between exposure to sugar cane manufacturing processes and tuberculosis infection among indigenous populations.

    Active Pharmaceutical Ingredients (API) raw material variability is not always thoroughly considered during pharmaceutical process development, mainly due to low quantities of drug substance available. However, synthesis, crystallization routes and production sites evolve during product development and product life cycle leading to changes in physical material attributes which can potentially affect their processability. Recent literature highlights the need for a global approach to understand the link between material synthesis, material variability, process and product quality. The study described in this article aims at explaining the raw material variability of an API using extensive material characterization on a restricted number of representative batches using multivariate data analysis. It is part of a larger investigation trying to link the API drug substance manufacturing process, the resulting physical API raw material attributes and the drug product continuous manufacturing process. Eight API batches produced using different synthetic routes, crystallization, drying, delumping processes and processing equipment were characterized, extensively. Seventeen properties from seven characterization techniques were retained for further analysis using Principal Component Analysis (PCA). Three principal components (PCs) were sufficient to explain 92.9% of the API raw material variability. The first PC was related to crystal length, agglomerate size and fraction, flowability and electrostatic charging. The second PC was driven by the span of the particle size distribution and the agglomerates strength. The third PC was related to surface energy. Additionally, the PCA allowed to summarize the API batch-to-batch variability in only three PCs which can be used in future drug product development studies to quantitatively evaluate the impact of the API raw material variability upon the drug product process. The approach described in this article could be applied to any

    Phage endolysins have received increased attention in recent times as potential antibacterial agents and the biopreservatives in food production processes. Staphylococcus aureus is one of the most common pathogens in bacterial food poisoning outbreaks. In this study, the endolysin Lysdb, one of the two-component cell lysis cassette of Lactobacillus delbrueckii phage phiLdb, was shown to possess a muramidase domain and catalytic sites with homology to Chalaropsis-type lysozymes. Peptidoglycan hydrolytic bond specificity determination revealed that Lysdb was able to cleave the 6-O-acetylated peptidoglycans present in the cell walls of S. aureus. Turbidity reduction assays demonstrated that Lysdb could effectively lyse the S. aureus live cells under acidic and mesothermal conditions. To further evaluate the ability of Lysdb as a potential antibacterial agent against S. aureus in cheese manufacture, Lactobacillus casei BL23 was engineered to constitutively deliver active Lysdb to challenge S. aureus in lab-scale cheese making from raw milk. Compared with the raw milk, the viable counts of S. aureus were reduced by 10(5)-fold in the cheese inoculated with the engineered L. casei strain during the fermentation process, and the pathogenic bacterial numbers remained at a low level (10(4) CFU/g) after 6 weeks of ripening at 10 °C. Taken together, all results indicated that the Lysdb has the function as an effective tool for combating S. aureus during cheese manufacture from raw milk.

    Ensuring the virological safety of biologicals is challenging due to the risk of viral contamination of raw materials and cell banks, and exposure during in-process handling to known and/or emerging viral pathogens. Viruses may contaminate raw materials and biologicals intended for human or veterinary use and remain undetected until appropriate testing measures are employed. The outbreak and expansive spread of the mosquito-borne flavivirus Zika virus (ZIKV) poses challenges to screening human- and animal -derived products used in the manufacture of biologicals. Here, we report the results of an in vitro study where detector cell lines were challenged with African and Asian lineages of ZIKV. We demonstrate that this pathogen is robustly detectable by in vitro assay, thereby providing assurance of detection of ZIKV, and in turn underpinning the robustness of in vitro virology assays in safety testing of biologicals.

  20. Lack of Detection of Bt Sugarcane Cry1Ab and NptII DNA and Proteins in Sugarcane Processing Products Including Raw Sugar

    2018-03-01

    Full Text Available Brazil is the largest sugarcane producer and the main sugar exporter in the world. The industrial processes applied by Brazilian mills are very efficient in producing highly purified sugar and ethanol. Literature presents evidence of lack of DNA/protein in these products, regardless of the nature of sugarcane used as raw material. Recently CTNBio, the Brazilian biosafety authority, has approved the first biotechnology-derived sugarcane variety for cultivation, event CTC175-A, which expresses the Cry1Ab protein to control the sugarcane borer (Diatraea saccharalis. The event also expresses neomycin-phosphotransferase type II (NptII protein used as selectable marker during the transformation process. Because of the high purity of sugar and ethanol produced from genetically modified sugarcane, these end-products should potentially be classified as “pure substances, chemically defined,” by Brazilian Biosafety Law No. 11.105. If this classification is to be adopted, these substances are not considered as “GMO derivatives” and fall out of the scope of Law No. 11.105. In order to assess sugar composition and quality, we evaluate Cry1Ab and NptII expression in several sugarcane tissues and in several fractions from laboratory-scale processing of event CTC175-A for the presence of these heterologous proteins as well as for the presence of traces of recombinant DNA. The results of these studies show that CTC175-A presents high expression of Cry1Ab in leaves and barely detectable expression of heterologous proteins in stalks. We also evaluated the presence of ribulose-1,5-bisphosphate carboxylase/oxygenase protein and DNA in the fractions of the industrial processing of conventional Brazilian sugarcane cultivars. Results from both laboratory and industrial processing were concordant, demonstrating that DNA and protein are not detected in the clarified juice and downstream processed fractions, including ethanol and raw sugar, indicating that protein

    The aim of this study was to determine the transmission routs of Listeria spp. in dairy farms manufacturing fresh cheese made from ovine and caprine raw milk and to evaluate the impact of Listeria monocytogenes mastitis on raw milk contamination. Overall, 5,799 samples, including 835 environmental samples, 230 milk and milk product samples, and 4,734 aseptic half-udder foremilk samples were collected from 53 dairy farms in the dairy intensive area of Lower Austria. Farms were selected for the study because raw milk was processed to cheese that was sold directly to consumers. A total of 153 samples were positive for Listeria spp., yielding an overall prevalence of 2.6%; L. monocytogenes was found in 0.9% of the samples. Bulk tank milk, cheese, and half-udder samples were negative for Listeria spp. Because none of the sheep and goats tested positive from udder samples, L. monocytogenes mastitis was excluded as a significant source of raw milk contamination. L. monocytogenes was detected at 30.2% of all inspected farms. Swab samples from working boots and fecal samples had a significantly higher overall prevalence (P < 0.001) of L. monocytogenes (15.7 and 13.0%, respectively) than did swab samples from the milk processing environment (7.9%). A significant correlation was found between the prevalence of L. monocytogenes in the animal and in the milk processing environment and the silage feeding practices. Isolation of L. monocytogenes was three to seven times more likely from farms where silage was fed to animals throughout the year than from farms where silage was not fed to the animals.

    The aim of this paper was to analyze the sugar cane bagasse ash from three Sugar and Alcohol Plant of the State of Sao Paulo - Brazil. We intend to show the discrepancies between them, so that this raw material could be used with greater quality control in ceramic industries. The bagasse were analyzed by differential scanning calorimetry (DSC), thermogravimetry (TG) and scanning electron microscopy. The ashes were analyzed by X-ray diffraction, X-ray fluorescence, scanning electron microscopy, energy dispersive spectroscopy, and granulometric separation. The results indicated that the content of SiO{sub 2} ranging from 50-80% by weight depends on the granulometry of the bagasse and on the region where it was collected. The analyses of X-ray diffraction indicate SiO{sub 2}, Fe{sub 2}O{sub 3}, K{sub 2}SO{sub 4} and Mg{sub 2}P{sub 2}O{sub 7} as crystalline phases. (author)

    An improved continuous fermentation technique consists of using a special strain of yeast, GN/1942-2 (C), having high attenuating power and high alcohol tolerance which can function efficiently in the higher concentrations of sugars necessary to produce a mash containing 10 to 12% alcohol. The yeast is fed with suitable nutrients in the pre-fermentors at a regulated rate to maintain a constant cell population at all stages, thus enhancing the speed of fermentation. Thus, double the normal quantity of molasses can be fermented without sacrificing the efficiency of fermentation.

    Glass-ceramic material prepared with sugar cane bagasse ash as one of the raw materials was characterized to determine some important properties for its application as a coating material. X-ray diffraction patterns showed that wollastonite-2M (CaSiO{sub 3}) was the major glass-ceramic phase. The Rietveld method was used to quantify the crystalline (60 wt.%) and vitreous (40 wt.%) phases in the glass-ceramic. The microstructure (determined by scanning electron microscopy) of this material had a marble appearance, showing a microporous network of elongated crystals with some areas with dendritic, feather-like ordering. Microhardness data gave a mean hardness value of 564.4 HV (Vickers-hardness), and light microscopy disclosed a greenish brown colored material with a vitreous luster. - Highlights: • We studied the properties of a glass-ceramic material obtained from sugarcane ash. • This material has the appearance and hardness of natural stones. • A refining method gave information about its amorphous and crystalline phases. • This material has potential to be used as coating plates for buildings.

    2010-01-01

    Full Text Available Increasing exports by stimulating the foreign direct investment could be a solution to the problem of the persistent trade balance deficit of Romania. However, in such an attempt there have to be taken into consideration the potential effects of the foreign direct investment on some categories of imports. This paper explores the dynamic relation between the foreign direct investment from the manufacturing sector and the Romanian imports of intermediate goods and raw materials. We found causality linkages between the foreign direct investment and the imports of intermediate goods, meaning that Romanian branches of the multinational companies prefer to import such goods instead of producing or buying from the domestic markets. Instead, we failed to identify any causality between the foreign direct investment and the imports of raw materials.

    assortments was undertaken using a small Metador press machine. To study the effect of variations in the raw material on pellets quality, the setting of the press equipment was kept unchanged during the pressing of all assortments. Many technical difficulties were encountered during the small-scale manufacturing of the pellets. We only succeeded in pelletizing sawdust from fresh and four-months stored pine but not from 8-months stored pine or spruce assortments. The ash content in sawdust taken from different material was low and varied between 0.2 and 0.35 % of dry weight. The content of ash in the small-scaled produced pellets was close to that of the raw material. The initial average calorific heating values of pine, both thin and large diameter trees, were higher than that of spruce. The concentration of extractives, both those extracted with acetone or with alcohol, were generally higher in pine compared to spruce samples. A marked increase in the concentration of alcohol-soluble extractives was measured during the storing of sawdust from both pine and spruce. The pellets made from this material showed a similar pattern. This increase possibly reflects changes in some chemical components that were affected by the high temperature developed during storage. Attempts to relate the changes occurred in the raw material to the quality of the produced pellets were not totally successful partly due to the large variations within the raw material itself and partly because of the failure to palletise certain assortments. However, general conclusion are still possible to draw. The compact density of individual pellets varied very little between various samples produced by the small-scale pelletizing method. Similar results were obtained in pellets manufactured at the industrial factories. The durability of pellets produced using the small-scale method was generally higher when the raw material was stored before pelletizing. This observation is in agreement with the general opinion

    In order to decrease environmental impact, caused by mud discarding and clay extraction in the ceramic industry, it was used residual mud from marble and granite companies for structural ceramic. Samples were collected in twelve different marble companies located at the metropolitan region of Sao Paulo. However, only four samples were selected, based on its different characteristics. Clay stone was the raw material chosen to prepare the structural ceramic, considering its high use in this segment. Samples and clay stone were both analysed by the following procedures: granulometric analysis, x-rays fluorescent chemical analysis and x-rays diffraction mineralogical analysis, besides, tests in the samples were conducted following NBR 10004 standards. Once raw materials were characterized, the plasticity test was conducted. Test specimen were molded with different levels of mud, then burned and submitted to technological tests, such as: mechanical resistance, water absorption, porosity, specific gravity and retraction, material dilation before burning process and scanning electron microscopy. The final results have shown the viability of using this kind of mud, and pointed some advantages on its usage, but taking in consideration some previous conditions to be adopted. (author)

    Based on results of evaluation and breeding programmes with beets, potato, Jerusalem artichoke and chicory the following conclusions can be drawn: For breeding beets with a high sugar yield it seems favourable to produce hybrids between sugar and fodder beet. Compared to the average of their parents the sugar beet x fodder beet and fodder beet x sugar beet hybrids produced 3,8 and 12,9% resp., higher sugar yields. It is, however, from this experiment not fully clear if heterosis allone is the explanation for this increase. Several preselected populations of the primitive potato species S. tuberosum subsp. andigena and S. phureja from the United States, Scotland and the Netherlands have been tested in a field trial. Compared to Phureja the Andigena material has reached a high level of adaptation. An immediate use in commercial breeding programmes for the production of high yielding Tuberosum-Andigena hybrids is possible. In Jerusalem artichoke the production of new genetic variability by crossing is complicated by the bad fertility of this species. Because of the very limited breeding activities in the past a large advance is possible. Even though the species C. intybus is of many shapes, only the root chicory is suitable for use as an industrial crop. Leaf chicory produces only low to medium sugar yields and is badly adapted to mechanical harvest. (orig.)

    Research undertaken in France on the upgrading of colliery shale has made it possible to extend the range of markets available for these products and to promote their utilization either in the untreated state or after processing. In the more specific field of lightweight building materials, our research has culminated in the development of manufacturing processes for aggregates and expanded nodular sands. The 100 mat3/day factory stage in the case of aggregates and the pilot plant (capacity several hundred kg/h) stage in the case of sands has been reached. However, the overall picture of slack demand for lightweight aggregates on the French market is little incentive for the rapid industrial development of manufacture of these materials.

    Tests were carried out to determine the effect of manufacturing procedures for a Camembert-type cheese from raw goats' milk on the growth and survival of Staphylococcus aureus organisms added to milk at the start of the process, and to study the possible presence of staphylococcal enterotoxin A in these cheeses. The initial staphylococcal counts were, respectively, 2, 3, 4, 5 and 6 log cfu ml-1. Cheese was prepared following the industrial specifications and ripened for 41 d. Detection of enterotoxins was done by the Vidas SET test and by an indirect double-sandwich ELISA technique using antienterotoxin monoclonal antibodies. Generally, numbers of microbes increased at a similar rate during manufacture in all cheeses until salting. During the ripening period, the aerobic plate count population and Staph. aureus levels remained stable and high. There was an approximately 1 log reduction of Staph. aureus in cheeses made with an initial inoculum of Staph. aureus greater than 10(3) cfu ml-1 at the end of the ripening period (41 d) compared with the count at 22 h. The level of staphylococcal enterotoxin A recovered varied from 1 to 3.2 ng g-1 of cheese made with an initial population of 10(3)-10(6) cfu ml-1. No trace of enterotoxin A was detected in cheeses made with the lowest Staph. aureus inoculum used in this study.

    Sugars are used by the industry to enhance the attractiveness of foods and drinks. These added sugars, or 'free sugars', are not easily identified in food or drink labels. Certain manufactured foods and drinks with 'safe' names, such as dried fruit and fruit juice, still contain free sugars and can be confusing. Guidance states that daily consumption of free sugars should be less than 10% of total energy intake (no more than 5% in the UK). However, it is found that both tooth decay and obesity are associated with consumption of free sugars in large quantities and at inappropriate times.

    Full Text Available Introduction: The consumption of meals outside the home has become an increasingly common practice in the life of the Brazilian population and of everyone. Objective: The aim of this work was to evaluate the microbiological quality of raw white cabbage (Brassica oleracea var. capitata f. alba, served in an institutional self-service restaurant, in the different stages of processing (reception, sanitation, slicing, cooling and distribution. In addition, Good Manufacturing Practices (GMP were evaluated through a checklist. Method: Total coliform, Escherichia coli and total aerobic bacteria were counted and Salmonella spp. was searched. Results: A sample collected at the reception stage showed Salmonella spp. Sanitization eliminated Salmonella spp. and reduced total coliforms and E. coli to undetectable numbers. The environment, the equipment and the manipulation strongly influenced the microbiological quality of food. Samples collected on day 4, after slicing, showed 3.2 log CFU of E. coli per g and at distribution 4.1 log CFU/g, which indicates unsatisfactory hygienic conditions. The restaurant had 55.75% compliance with GMP items, being classified as regular (Group 2, in accordance with RDC n° 275/2002. Conclusions: The non-conformities (37.00% observed in the exposure to prepared food consumption may be influencing the microbiological quality of raw white cabbage salad served. In this way we highlight the importance of the application of GMP in the production process to obtain a safe food and the compliance with the four POP required by RDC n° 216/2004.

    The thermal behaviour, mineralogy, texture and micro-structure of the original rocks used as raw materials in the manufacture of ceramics of the potter community in Fran Ali (Oued Laou, Tetouan, Morocco) were studied. The original rocks of the alteration deposit are metapelites and altered philites from the Units Malaguide-Gomaride in the Baetic-Rifian mountain system. The techniques used by local potters and the water used to prepare the ceramic bodies were also studied. Original rocks are metapelites or filadios and raw materials belong to levels caused by exogenous or supergene alteration (quartz-illite and chlorite type clays). The ceramics studied by microscopy exhibit anisotropy. (Author) 15 refs.

    The factor which determines the economy in the EtOH industry which uses sugar beets as raw materials is the rapid and complete recovery of the sugar contained in the beets for fermentation purposes. It is best to extract the beets at 70 to 75/sup 0/. Thorough shredding of the beets then need no longer form part of the operation, and the protein compounds, which give rise to fuel oils, are extracted in small amounts only.

This study compared the growth potential of Listeria monocytogenes on cheeses manufactured from raw or pasteurized milk and held for > 60 days at 4 degrees C. Final cheeses were within federal standards of identity for soft ripened cheese, with low moisture targets to facilitate the holding period. Wheels were surface inoculated with a five-strain cocktail of L. monocytogenes at approximately 0.2 CFU/ cm2 (low level) or 2 CFU/cm2 (high level), ripened, wrapped, and held at 4 degrees C. Listeria populations began to increase by day 28 for all treatments after initial population declines. From the low initial inoculation level, populations in raw and pasteurized milk cheese reached maximums of 2.96 +/- 2.79 and 2.33 +/- 2.10 log CFU/g, respectively, after 60 days of holding. Similar growth was observed in cheese inoculated at high levels, where populations reached 4.55 +/- 4.33 and 5.29 +/- 5.11 log CFU/g for raw and pasteurized milk cheeses, respectively. No significant differences (P milk types. Independent of the milk type, cheeses held for 60 days supported growth from very low initial levels of L. monocytogenes introduced as a postprocess contaminant. The safety of cheeses of this type must be achieved through control strategies other than aging, and thus revision of current federal regulations is warranted.

    This paper describes the achievement in fiscal 1997 of analyzing practical application of a technology to manufacture solar cell silicon raw materials. Silicon consumption for solar cells in fiscal 1997 has increased to 2000-ton level, and the supply has been very tight. For drastic improvement in the demand and supply situation, development of SOG-Si manufacturing technology and its early practical application are desired. The development of the NEDO mass-production technology using melting and refining has completed constructing the process facilities in fiscal 1998, and will enter the stage of operational research. However, insufficiency in the basic data about behavior of impurities is inhibiting the development. In the substrate manufacturing technology, discussions have shown progress on use of diversifying silicons outside the standard by using the electromagnetic casting process. For slicing and processing the substrates, development of a high-performance slicing equipment and automatic rough rinsing machine is under way. Properties required on silicon raw materials vary considerably widely because of difference in cell making systems and conditions, which is attributable to unknown impurity behavior. When 1GW production is assumed, the cell module manufacturing cost is calculated as 137 yen/W, for which low-cost mass production for its realization, slicing productivity enhancement, and cost reduction are required. The paper also describes site surveys in overseas countries. (NEDO)

    In order to support the development and practical application of a mass production technology for manufacturing silicon raw materials for solar cells, research and study were performed on trends of developing the related technologies, and movements in markets and industries. This paper reports the achievements thereof in fiscal 1999. Markets for solar cells are growing favorably, and the worldwide solar cell production in 1999 was 200 MWp, of which 80% or more is occupied by crystalline silicon solar cell. While development of the manufacturing technology for SOG-Si mass-production is in the stage of operation research of pilot plants, it has been verified that problems of impurity contamination was resolved, and high-purity silicon can be manufactured. In developing the silicon scrap utilization technology and a technology to integrate silicon refinement with casting, a conversion efficiency of 14% or higher was acquired in prototype sample substrates. It has been verified that a variety of raw materials can be dealt with by using the above technology, which has a possibility of cost reduction. In developing a substrate manufacturing technology, a great progress has been made in enhancing the productivity and reducing the cost by developing the continuous casting in the electromagnetic casting and the automation technology.

    The demand for gluten-free foods is certainly increasing. Interest in teff has increased noticeably due to its very attractive nutritional profile and gluten-free nature of the grain, making it a suitable substitute for wheat and other cereals in their food applications as well as foods for people with celiac disease. The main objective of this article is to review researches on teff, evaluate its suitability for different food applications, and give direction for further research on its applications for health food market. Teff is a tropical low risk cereal that grows in a wider ecology and can tolerate harsh environmental conditions where most other cereals are less viable. It has an excellent balance of amino acid composition (including all 8 essential amino acids for humans) making it an excellent material for malting and brewing. Because of its small size, teff is made into whole-grain flour (bran and germ included), resulting in a very high fiber content and high nutrient content in general. Teff is useful to improve the haemoglobin level in human body and helps to prevent malaria, incidence of anaemia and diabetes. The nutrient composition of teff grain indicates that it has a good potential to be used in foods and beverages worldwide. The high levels of simple sugars and α-amino acids as a result of breakdown of starch and protein, respectively, are essential for fermentation and beer making.

This paper summarizes the achievements in fiscal 1998. The worldwide production amount of solar cells in 1998 is estimated to have achieved 150 MW, and the silicon consumption reached the level of 2,300 tons. In spite of the economic recession environment, there was no change in the expansion trend. In developing an SOG-Si mass production and manufacturing technology, construction of pilot plants for each process has been completed, and entered into the operation research phase. In developing a technology to manufacture high quality poly-crystalline silicon substrates, fabrication has been completed on the on-line ingot cutting equipment and the plasma heating equipment, and the stage is now in operation research of continuous electromagnetic casting process. The conversion efficiency of the poly-crystalline silicon solar cells is 14 to 16% at the mass production level, whose enhancement requires indispensably the improvement in quality of the substrate. Discussions are required on the ingot manufacturing conditions in coordination with improvement in the cell manufacturing technology. (NEDO)

    Anthocyanin, which is soluble in water and released into sugar steam during extraction, was investigated in this study. The anthocyanin content in refined sugar, plantation white sugar, soft brown sugar and raw sugar was determined using electron spin resonance (ESR) spectroscopy, which was operated at room temperature, and compared with spectra from standard anthocyanin. The ESR spectra of red and violet anthocyanins was predominantly g ≈ 2.0055, which corresponded to an unpaired electron located in the pyrylium ring. Signals for Fe(III) and Mn(II), which naturally occur in plants, were found in raw sugar, soft brown sugar and standard anthocyanin but were absent from refined sugar and plantation white sugar due to the refining process. In addition, the ESR results were correlated with the apparent colour of the sugar, which was determined using the method of the International Commission for Uniform Methods of Sugar Analysis and inductively coupled plasma optical emission spectroscopy.

    Sugarcane has been used as raw material in crystal sugar industry. Sugar cane that contains high sugar will be utilized into crystals sugar. In addition, the productivity of sugarcane is large enough in 2016 approximately 360 713 tons/year. Crystal sugar itself is a daily necessity for its use in the food and beverage industry. Problem that occurs in Indonesia is the energy consumption. The sugar mills supposed to be an independent energy source which means it can produce its own energy by utilization the material that is available in the sugar mills such as by-product (bagasse, molasses, filter cake, etc.), the by product in every production stage are quite a lot in sugar industry especially in Indonesia. In this paper, a comparison between two sugar mills was examined between Ngedirejo sugar mill and Mauritius sugar mill which has the same geological state as Indonesia. The results of comparison between the two sugar factories demonstrated the difference in terms of productivity of the sugar that has been produced and the effectiveness of the production process in a sugar mill seen from the amount of waste and the by product.

    Directory of Open Access Journals (Sweden)

    Gillian Eggleston

    2015-09-01

    Full Text Available Like many other industries, the sugar and sugar-bioproduct industries are facing important sustainability issues and opportunities. The relatively low and fluctuating profit for sugar, surpluses of sugar, world-wide trend to produce alternative, renewable bio-based fuels and chemicals to those derived from petroleum and reduce greenhouse gases, water- and energy-intensive factories and refineries, and increased consumer demands for sustainably manufactured products are putting pressure on the industries to diversify for sustainability. Sugar crops, including sugar and energy cane (Saccharum officinarum, sugar and energy beets (Beta vulgaris, and sweet sorghum (Sorghum bicolor L. Moench, are excellent, renewable biomass feedstocks because of their availability, their being amongst the plants that give the highest yields of carbohydrates per hectare, and high sugar contents. While much research has been focused on conversion technologies for advanced biofuels and bioproducts, attention is now focused on developing sustainable supply chains of sugar feedstocks for the new, flexible biorefineries, with customers wanting maximum feedstock reliability and quality, while minimizing cost. All biomass from sugar crops are potential feedstocks. The cogeneration of bioelectricity from bagasse and leaf residues is being increasingly manufactured in more countries and, due to the high carbon content of bagasse and leaves, can also be converted into value-added products such as biochar. Sugar crops are superior feedstocks for the production of platform chemicals for the manufacture of a range of end-products, e.g., bioplastics, chemicals, and biomaterials. In several countries and regions, green sustainability criteria are now in place and have to be met to count against national biofuel targets. Processes to convert high-fiber sugar crop biomass into biofuel have been developed but there has only been limited commercialization at the large-scale.

  13. Sugars as tobacco ingredient: Effects on mainstream smoke composition.

    Science.gov (United States)

    Talhout, Reinskje; Opperhuizen, Antoon; van Amsterdam, Jan G C

    2006-11-01

    Sugars are natural tobacco components, and are also frequently added to tobacco during the manufacturing process. This review describes the fate of sugars during tobacco smoking, in particular the effect of tobacco sugars on mainstream smoke composition. In natural tobacco, sugars can be present in levels up to 20 wt%. In addition, various sugars are added in tobacco manufacturing in amounts up to 4 wt% per sugar. The added sugars are usually reported to serve as flavour/casing and humectant. However, sugars also promote tobacco smoking, because they generate acids that neutralize the harsh taste and throat impact of tobacco smoke. Moreover, the sweet taste and the agreeable smell of caramelized sugar flavors are appreciated in particular by starting adolescent smokers. Finally, sugars generate acetaldehyde, which has addictive properties and acts synergistically with nicotine in rodents. Apart from these consumption-enhancing pyrolysis products, many toxic (including carcinogenic) smoke compounds are generated from sugars. In particular, sugars increase the level of formaldehyde, acetaldehyde, acetone, acrolein, and 2-furfural in tobacco smoke. It is concluded that sugars in tobacco significantly contribute to the adverse health effects of tobacco smoking.

  14. Evaluation of Apple Pomace as a Raw Material for Alternative Applications in Food Industries

    2007-01-01

    Full Text Available In order to measure the potential of apple pomace as a raw material for manufacturing food-related products (such as lactic acid, fiber-rich concentrates and pectin, samples from cider industry were assayed for composition and enzymatic digestibility. Alcohol-soluble compounds (monosaccharides, oligosaccharides and malic acid accounted for 32–45 mass percent of oven-dry pomace. Glucose and fructose were the major components of this fraction. The alcohol-insoluble fraction accounted for 55–68 mass percent of oven-dry pomace and was mainly made up of neutral detergent fiber (62–69 percent of the mass fraction and pectin (16.2–19.7 percent of the mass fraction. The feedstock content of N, P and metal ions (K, Mg, Fe and Mn was favourable for further manufacture of lactic acid fermentation media. Apple pomace showed a high susceptibility to enzymatic hydrolysis: in media with a cellulase loading of 8.5 FPU/g of apple pomace and a cellobiase loading of 5 IU/FPU, about 80 % of the total glucan was converted into glucose after 15 h. Considering the low enzyme charge, liquor to solid ratio employed, reaction time needed to achieve the maximal sugars concentration and N, P and metal ion (K, Mg, Fe and Mn content of samples, it can be concluded that apple pomace is a promising raw material for lactic acid production.

    Full Text Available Contrary to the safe practices of milk pasteurization or sterilization, which effectively reduce foodborne outbreaks incidence associated with raw milk and dairy products use, outbreaks caused by such products continue to occur. Despite this fact, a worldwide movement advocating for the rights of raw milk and cheese selling and consumption, due to their specific nutritive characteristics, has strengthened significantly in recent years. Traditional agricultural manufacturers from Serbia still sell products related to thermally unprocessed milk, such as cottage cheese and raw cream. In AP Vojvodina during the period of 1981-2010 a total of 179 foodborne outbreaks were reported, where the incriminated cause of the outbreak were milk or diary. In 126 (70.39% outbreaks, totaling 2276 sick individuals and one casualty, it was confirmed that the incriminated food was from the group of dairy products. In 48 instances (26.82%, bacteriological tests confirmed that milk and dairy products were excluded as the outbreak causes, while in another 5 (2.79% outbreaks, microbiological analysis of food failed to confirm any relation to the actual epidemiological instances. In some cases, bacteriological testing of incriminated foods was not possible. In the cases of outbreaks associated with the consumption of milk and dairy products, traditional raw milk products were cited as being used. Consumption of unpasteurized milk and cheese represents public health threat. National and international rules ensuring use of safe products for human consumption have to set rules of trade of thermally processed milk and products on the market.

    An increasing number of people are consuming raw unpasteurized milk. Enhanced nutritional qualities, taste, and health benefits have all been advocated as reasons for increased interest in raw milk consumption. However, science-based data to substantiate these claims are limited. People continue to consume raw milk even though numerous epidemiological studies have shown clearly that raw milk can be contaminated by a variety of pathogens, some of which are associated with human illness and disease. Several documented milkborne disease outbreaks occurred from 2000-2008 and were traced back to consumption of raw unpasteurized milk. Numerous people were found to have infections, some were hospitalized, and a few died. In the majority of these outbreaks, the organism associated with the milkborne outbreak was isolated from the implicated product(s) or from subsequent products made at the suspected dairy or source. In contrast, fewer milkborne disease outbreaks were associated with consumption of pasteurized milk during this same time period. Twenty nine states allow the sale of raw milk by some means. Direct purchase, cow-share or leasing programs, and the sale of raw milk as pet food have been used as means for consumers to obtain raw milk. Where raw milk is offered for sale, strategies to reduce risks associated with raw milk and products made from raw milk are needed. Developing uniform regulations including microbial standards for raw milk to be sold for human consumption, labeling of raw milk, improving sanitation during milking, and enhancing and targeting educational efforts are potential approaches to this issue. Development of pre- and postharvest control measures to effectively reduce contamination is critical to the control of pathogens in raw milk. One sure way to prevent raw milk-associated foodborne illness is for consumers to refrain from drinking raw milk and from consuming dairy products manufactured using raw milk.

    Full Text Available Sugar, with good taste and high caloric, is one of the most popular human food. Consumers sugar must be sure that the sugar under normal conditions of use is of high quality and is not harmful to the health of the product. One reason for the decline in the quality of sugar is bacterial contamination. This is because the sugar industry products are good targets for the development of different groups of microorganisms, e.g., Bacillus subtilis, Clostridium perfringes, Leuconostoc dextranicum, Torula alba, Pseudomonas fluorescens, Sarcina lutea and others. These organisms are affected with beets, and then with sugar beet chips and diffusion juice fall into the processing line of sugar production. Their number in the diffusion juice varies and depends on many facto rs such as the quality of raw materials, the quality of cleaning beet root colonization of transporter-washing and the supply of water to the diffusion process, the temperature of the diffusion and others. In the diffusion unit has the most favorable conditions for the development of micro-organisms. Some of them, especially resistant bacteria and thermophilic bacteria or their spores, forming a capsule which protects against external influences occur in the final product sugar. When injected into the fresh crop of product (juice, syrup, they begin to multiply rapidly, causing difficulties in the process. The higher seeding beet microorganisms, the more they decompose and emit sucrose metabolism byproducts. To reduce the negative impact of microbiological and reduce losses from decomposition of sucrose conducted research on the possibility of using chlorine-containing substances in the sugar industry. It was established experimentally that the investigated chlorinated drug has bacteriostatic action and can be recommended for use in sugar beet production.

    In order to decrease environmental impact, caused by mud discarding and clay extraction in the ceramic industry, it was used residual mud from marble and granite companies for structural ceramic. Samples were collected in twelve different marble companies located at the metropolitan region of Sao Paulo. However, only four samples were selected, based on its different characteristics. Clay stone was the raw material chosen to prepare the structural ceramic, considering its high use in this segment. Samples and clay stone were both analysed by the following procedures: granulometric analysis, x-rays fluorescent chemical analysis and x-rays diffraction mineralogical analysis, besides, tests in the samples were conducted following NBR 10004 standards. Once raw materials were characterized, the plasticity test was conducted. Test specimen were molded with different levels of mud, then burned and submitted to technological tests, such as: mechanical resistance, water absorption, porosity, specific gravity and retraction, material dilation before burning process and scanning electron microscopy. The final results have shown the viability of using this kind of mud, and pointed some advantages on its usage, but taking in consideration some previous conditions to be adopted. (author)

    1999-01-01

    Wood pellets have many advantages compared to other fuels. It is longest processed biofuel with favorable energy content. It is simple to use, transport and store. Heating with wood pellets is cheaper than with light fuel oil, and approximately as cheap as utilization of heavy fuel oil, about 110 FIM/MWh. The taxable price of wood pellets is about 550 FIM/t. Stokers and American iron stoves are equally suitable for combustion of wood pellets. Chip fueled stokers are preferred in Finland, but they are also suitable for the combustion of wood pellets. Wood pellets is an environmentally friendly product, because it does not increase the CO 2 load in the atmosphere, and its sulfur and soot emissions are relatively small. The wood pelletizing plant of Biowatti Oy in Turenki was started in an old sugar mill. The Turenki sugar mill was chosen because the technology of the closed sugar factory was suitable for production of wood pellets nearly as such, and required only by slight modifications. A press, designed for briquetting of sugar beat clippings makes the pellets. The Turenki mill will double the volume of wood pellet manufacture in Finland during the next few years. At the start the annual wood pellet production will be 20 000 tons, but the environmental permit allows the production to be increased to 70 000 tons. At first the mill uses planing machine chips as a raw material in the production. It is the most suitable raw material, because it is already dry (moisture content 8-10%), and all it needs is milling and pelletizing. Another possible raw material is sawdust, which moisture content is higher than with planing machine chips. Most of the wood pellets produced are exported e.g. to Sweden, Denmark and Middle Europe. In Sweden there are over 10 000 single-family houses using wood pellets. Biowatti's largest customer is a power plant located in Stockholm, which combusts annually about 200 000 tons of wood pellets

    In order to keep the pellet prices stable, producers look for new raw materials. Sawdust as a former basis also competes with the manufacturers of chip boards and paper. Three classes of quality are discussed by the pellet manufacturers: (a) the DINplus pellet as a premium segment for which high-quality sawdust are used; (b) a wood pellet from natural wood with varying quality for the utilization in larger plants with filters; (c) the inexpensive industrial wood pellet which deviates from the DINplus commodity regarding to the ingredients and form and could be fired in larger power stations.

  12. Raw materials for reflector graphite (for reactors)

    Wilhelmi, G.; Mindermann, D.

    1992-01-01

    The manufacturing concept for the core components of German high temperature reactor (HTR) types of graphite was previously entirely directed to the use of German tar coke (St coke). As the plants for producing this material no longer complied technically with the current environmental protection requirements, one had to assume that they would soon be shut down. To prevent bottlenecks in the erection of future HTR plants, alternative cokes produced by modern processes by Japanese manufacturers were checked for their suitability for the manufacture of reactor graphite. This report describes the investigations carried out on these materials from the safe delayed coking process. The project work, apart from analysis of the main data of the candidate coke considered, included the processing of the raw materials into directly and secondarily extruded graphite rods on the laboratory scale, including characterisation. As the results show, the material data achieved with the previous raw material can be reproduced with Japanese St coke. The tar coke LPC-A from the Nippon Steel Chemical Co., Ltd was decided on as the new standard coke for manufacturing reflector graphite. (orig.) With 15 tabs., 2 figs [de

    In solving the problems in developing technologies peculiar to developing countries, Japan will provide cooperation. This paper describes the achievements in diagnosis and survey in fiscal 1994. Development will be made on a manufacturing process for dimethylether (DME), a synthesizable and portable clean fuel, by using coal produced in China. Annual DME production of 10,000 tons will make it possible to supply 50,000 households with the fuel of one year consumption, whereas return on the construction investment and profit can be expected. At the Shanxi Coal Chemistry Research Institute, a 500 tons a year plant making DME from gasified coal gas is scheduled to begin operation. Development will be made on a pulp manufacturing technology in China, in which environmental pollution due to waste water is largely reduced, and operation cost is reduced. Application of the oxygen-alkaline evaporation and decomposition process developed in Japan will be considered, which uses non-wood raw material such as rice straw, wheat straw and megass). The raw materials are immersed continually in low-concentration alkaline solution, dehydrated, and then lignin is oxidized and decomposed by using oxygen in a continuous oxidation reactor to make the material into pulp. China uses non-wood materials as paper raw materials at 80%, whereas effects are expected in waste water pollution prevention, energy saving, resource saving and economics. (NEDO)

  15. Catalytic production of sugar alcohols (polyols) and their application

    Energy Technology Data Exchange (ETDEWEB)

    Albert, R; Straetz, A; Vollheim, G

    1980-07-01

    The article surveys the numerous applications of the principal sugar alcohols sorbitol and xylitol and their world production in 1978. Nowadays, the industrial production of sugar alcohols is almost exclusively by catalytic hydrogenation of the corresponding sugars; thus sorbitol is manufactured by hydrogenation of D-glucose, xylitol by hydrogenation of xylose, and mannitol by hydrogenation of invert sugar or fructose. Some 80% of the world production of sugar alcohols are manufactured in batch suspension processes using Raney nickel catalysts. Apart from the Atlas Powder continuous suspension process employing nickel-carrier catalysts, continuous processes have recently been developed which use Raney nickel and prove more economical owing to the lower catalyst costs. Trickling processes with fixed catalyst continue to play a minor role. Available production capacity based on batch suspension processes can be expanded by process optimization and new catalyst developments. A newly developed special Raney nickel catalyst reduces the specific catalyst consumption by about 50%.

    2004-01-01

    Starch, whey or hemicellulosic waste can be used as a raw material for the industrial production of rare sugars. D-glucose from starch, whey and hemicellulose, D-galactose from whey, and D-xylose from hemicellulose are the main starting monosaccharides for production of rare sugars. We can produce all monosaccharides; tetroses, pentoses and hexoses, from these raw materials. This is achieved by using D-tagatose 3-epimerase, aldose isomerase, aldose reductase, and oxidoreductase enzymes or whole cells as biocatalysts. Bioproduction strategies for all rare sugars are illustrated using ring form structures given the name Izumoring.

  7. System simulation application for determining the size of daily raw material purchases at PT XY

    2018-02-01

    Every manufacturing company needs to implement green production, including PT XY as a marine catchment processing industry in Sumatera Utara Province. The company is engaged in the processing of squid for export purposes. The company’s problem relates to the absence of a decision on the daily purchase amount of the squid. The purchase of daily raw materials in varying quantities has caused companies to face the problem of excess raw materials or otherwise the lack of raw materials. The low purchase of raw materials will result in reduced productivity, while large purchases will lead to increased cooling costs for storage of excess raw materials, as well as possible loss of damage raw material. Therefore it is necessary to determine the optimal amount of raw material purchases every day. This can be determined by applying simulation. Application of system simulations can provide the expected optimal amount of raw material purchases.

    Full Text Available Summary. Priority social problem in the Russian Federation is to provide diverse populations rational healthy diet, taking into account their traditions and economic status. Solving this problem requires the development of processing industries of agriculture on the basis of the improvement of existing and creation of new energy-saving environmentally friendly technologies that can provide deep, if possible without waste, recycling of raw materials. Therefore, the aim of research was the development of technology for production of sugar beet chips. Technology is as follows: sugar beet supplied into the washing machine to remove dirt from its surface. Washed roots inspect on conveyor belts. Next pure sugar beets sent to steam-heat treatment for cleaning the skin. After the beets is subjected to cutting by combining this process with a treatment with an aqueous solution of citric acid. Then he sent for the drying process is completed upon reaching a product of moisture content of 4-5 %. Drying chips feature is that under the high temperature reaction proceeds melanoidins between proteins and sugars present in sugar beet. As a result, the product obtained has the following characteristics: gold-yellow color; absence of a characteristic odor of sugar beet; pleasant sour taste; humidity of 4-5%. Thus, the new technology is relevant, because now the chips are one of the most popular products, ready to eat. A beet chips are rich in dietary fiber (pectin, hemicellulose and cellulose - 4-5 % minerals - macroelements (potassium, sodium, magnesium, calcium, phosphorus, trace elements (iron, zinc, copper, manganese - 0.5-0.6 %, and are the product of a functional food.

    Oxidative damage is implicated in the etiology of cancer, cardiovascular disease, and other degenerative disorders. Recent nutritional research has focused on the antioxidant potential of foods, while current dietary recommendations are to increase the intake of antioxidant-rich foods rather than supplement specific nutrients. Many alternatives to refined sugar are available, including raw cane sugar, plant saps/syrups (eg, maple syrup, agave nectar), molasses, honey, and fruit sugars (eg, date sugar). Unrefined sweeteners were hypothesized to contain higher levels of antioxidants, similar to the contrast between whole and refined grain products. To compare the total antioxidant content of natural sweeteners as alternatives to refined sugar. The ferric-reducing ability of plasma (FRAP) assay was used to estimate total antioxidant capacity. Major brands of 12 types of sweeteners as well as refined white sugar and corn syrup were sampled from retail outlets in the United States. Substantial differences in total antioxidant content of different sweeteners were found. Refined sugar, corn syrup, and agave nectar contained minimal antioxidant activity (sugar had a higher FRAP (0.1 mmol/100 g). Dark and blackstrap molasses had the highest FRAP (4.6 to 4.9 mmol/100 g), while maple syrup, brown sugar, and honey showed intermediate antioxidant capacity (0.2 to 0.7 mmol FRAP/100 g). Based on an average intake of 130 g/day refined sugars and the antioxidant activity measured in typical diets, substituting alternative sweeteners could increase antioxidant intake an average of 2.6 mmol/day, similar to the amount found in a serving of berries or nuts. Many readily available alternatives to refined sugar offer the potential benefit of antioxidant activity.

    Brooks, L; Parravicini, V; Svardal, K; Kroiss, H; Prendl, L

    2008-01-01

    Sugar beet press pulp (SBP) accumulates as a by-product in sugar factories and it is generally silaged or dried to be used as animal food. Rising energy prices and the opening of the European Union sugar market has put pressure on the manufacturers to find alternatives for energy supply. The aim of this project was to develop a technology in the treatment of SBP that would lead to savings in energy consumption and would provide a more competitive sugar production from sugar beets. These goals were met by the anaerobic digestion of SBP for biogas production. Lab-scale experiments confirmed the suitability of SBP as substrate for anaerobic bacteria. Pilot-scale experiments focused on process optimization and procedures for a quick start up and operational control. Both single-stage and two-stage process configurations showed similar removal efficiency. A stable biogas production could be achieved in single-stage at a maximum volumetric loading rate of 10 kgCSB/(m(3) x d). Degradation efficiency was 75% for VS and 72% for COD. Average specific gas production reached 530 NL/kgCOD(SBP) or 610 NL/kgVS(SBP). (CH(4): 50 to 53%). The first large-scale biogas plant was put into operation during the sugar processing period 2007 at a Hungarian sugar factory. Digesting approximately 50% of the SBP (800 t/d, 22%TS), the biogas produced could substitute about 40% of the natural gas required for the thermal energy supply within the sugar processing.

    2014-12-01

    Full Text Available The article presents the results of the research on the current state of the beet sugar subcomplex of Ryazan region in the context of the need of improving its efficiency. The study let the author determine that currently the beet sugar subcomplex of Ryazan region does not ensure domestic demand in sand sugar. However, there are reserves of providing more efficient use of soil and climate capacity as well as the productivity potential of the region. When applying the technology of field beet piling, the period of sugar production at sugar factories may be extended up to 200 days. At this, up to 51 thousand tons of sand sugar can be produced. This amount will completely cover the annual demand for sugar in Ryazan region. In order to further study the feasibility of this approach, zoning was carried out and let allocate the zones of beet seeding. As a result, it was determined that a number of areas are far removed from the place of treatment, and in terms of transportation costs minimization the sugar beet cultivation in these areas is not rational. As an alternative, the author proposes to consider the possibility of building a new sugar factory in Ryazhsky district with the processing capacity of 1,000 tons of sugar beet per day. Taking this into account, the recommended acreage of sugar beet by districts and zones of raw material supply were obtained through corresponding calculations.

    Full Text Available Deficit of raw materials is becoming an important concern for the Chinese economy as it continues to grow. This deficit is amended with imports, which – in their own turn – are limited by the high level of global prices. The build-up issue of raw materials imports is going to solve by the measures of monetary policy (RMB’s revaluation against the USD. Analysis of China’s market of raw materials reveals that the largest increase in the physical volume of imports is concentrated in crude oil, LNG, iron ore and coal. As for Russia, its supplies and share in total Chinese imports of raw materials tend to increase. Author employs regression equations based on international statistics data to show that RMB’s revaluation, ceteris paribus, increases physical volumes of raw materials imports. However, the main factor of coal and LNG imports growth is energy consumption by Chinese heavy industry; imports of oil products – producers’ prices; meanwhile imports of steel products tend to decrease with the growth of steel exports. RMB’s revaluation increases physical volumes of imports of low value added raw materials from Russia (coal, crude oil, iron ore

    There is a direct link between a variety of addictions and mood states to which exercise could be relieving. Sugar addiction has been recently counted as another binge/compulsive/addictive eating behavior, differently induced, leading to a high-significant health problem. Regularly exercising at moderate intensity has been shown to efficiently and positively impact upon physiological imbalances caused by several morbid conditions, including affective disorders. Even in a wider set of physchiatric diseases, physical exercise has been prescribed as a complementary therapeutic strategy. A comprehensive literature search was carried out in the Cochrane Library and MEDLINE databases (search terms: sugar addiction, food craving, exercise therapy, training, physical fitness, physical activity, rehabilitation and aerobic). Seeking high-sugar diets, also in a reward- or craving-addiction fashion, can generate drastic metabolic derangements, often interpolated with affective disorders, for which exercise may represent a valuable, universal, non-pharmachological barrier. More research in humans is needed to confirm potential exercise-mechanisms that may break the bond between sugar over-consumption and affective disorders. The purpose of this review is to address the importance of physical exercise in reversing the gloomy scenario of unhealthy diets and sedentary lifestyles in our modern society.

    Acetic acid ethanol-based organosolv pretreatment of sugar cane bagasse was performed to enhance enzymatic hydrolysis. The effect of different parameters (including temperature, reaction time, solvent concentration, and acid catalyst dose) on pretreatment prehydrolyzate and subsequent enzymatic digestibility was determined. During the pretreatment process, 11.83 g of xylose based on 100 g of raw material could be obtained. After the ethanol-based pretreatment, the enzymatic hydrolysis was enhanced and the highest glucose yield of 40.99 g based on 100 g of raw material could be obtained, representing 93.8% of glucose in sugar cane bagasse. The maximum total sugar yields occurred at 190 °C, 45 min, 60:40 ethanol/water, and 5% dosage of acetic acid, reaching 58.36 g (including 17.69 g of xylose and 40.67 g of glucose) based on 100 g of raw material, representing 85.4% of total sugars in raw material. Furthermore, characterization of the pretreated sugar cane bagasse using X-ray diffraction and scanning electron microscopy analyses were also developed. The results suggested that ethanol-based organosolv pretreatment could enhance enzymatic digestibilities because of the delignification and removal of xylan.

    This paper introduced the sensor technology for food manufacturing industry. If sugar concentration in main raw material is too high in the amino acid fermentation, control of the concentration is required because fungi growth is inhibited. A controlling method for sugar concentration was developed by using the correlation between consumption of NH {sub 3} for pH adjustment and sugar consumption in place of conventional analyzing method and was introduced in the gulutamic acid fermantation. BOD sensor was developed to enable the selective measurement of organic substances which can be processed by organisms, and measuring time was shortened from previous five days to 30 minutes. Since many organics absorb infrared ray, near infrared analysis is suitable for food analysis and on-line analysis has high possibility. When this method is applied to measure moisture in fishes and meats, continuous measurement can be made nondestructively and without contacting, and further the precision is {plus minus} 0.1%. Simultaneous multi-composition analyses are carried out by continuous spectrum and near infrared method using higher rate scanning. Sensor development for taste and smell has started. 10 refs., 4 figs., 4 refs.

    1956-01-01

    Technological properties of cane sugar syrup, obtained on refining of raw cane sugar, were investigated. Its poor fermentation is caused by the lack of nitrous substances (1/10 as much as in sugar beet) necessary for the nutrition of yeast. It is necessary to introduce into the mixture of yeast and must 0.8% (NH/sub 4/)/sub 2/SO/sub 4/ based on weight of syrup (at a permanent aeration the assimilability of N from (NH/sub 4/)/sub 2/SO/sub 4/ by the yeast will be higher and the dosage has to be increased), 1% of superphosphate or 0.12% of a 70% phosphoric acid solution, and 0.5% of a yeast autolyst. For the fermentation of cane sugar syrup the mixture of yeast and must has to be prepared with a concentration of 10 to 11/sup 0/ by the saccharometer scale, but the average initial concentration of the fermentive must has to be 17 to 18/sup 0/ with the intention to keep the alcohol content of the ripe must at 8.7 to 8.8% by volume. Considering the low buffer ability of the syrup from cane sugar, the acidity of the must, mixed with yeast, has to be kept less than or equal to 0.4 to 0.5/sup 0/, the pH at 4.6 to 4.8; on a higher acidity the pH drops to a value which inhibits the fission of the yeast cells. On a joint fermentation of syrup from sugar cane and sugar beets 1% of superphosphate in the form of an aqueous extract and an autolyst of yeast in an amount of 0.5% of the weight of syrup was introduced into the must; the yield of alcohol from cane sugar syrup increased compared with the yield on separate processing.

  12. MICROFLORA OF BEET SUGAR PRODUCTION: PROBLEMS AND SOLUTIONS

    Full Text Available Summary. Sugar beet is one of the strategic crops for food safety of Russia. The lack of specialized warehouse for harvest does not provide storage of roots for a long time. In the case of a thaw roots that have been defrosted unsuitable for processing. Beet and products of its processing is a good object for the development of microorganisms. Permanent microflora of sugar production are: Bacillus subtilis, Clostridium perfringes, Leuconostoc dextranicum, Torula alba, Pseudomonas fluorescens, Sarcina lutea and other kinds of microorganisms, leading to a problem processing of beet root and reduced quality of sugar. The most dangerous is the slimy bacteriosis is a bacterial disease beet caused by heterofermentative cocci of Leuconostoc (Leuconostoc mesenteroides, L. dextranicum. Product of the vital activity of microorganisms is dextran, which is synthesized from sucrose as a result of dextrany or mucous fermentation and leads to significant technological problems in processing of infected beet. Improving the efficiency of sugar production is connected with decrease in loss of quality of raw material preparation, storing and processing of sugar beet. At sugar plants use a variety of drugs that suppress the growth of pathogenic microflora, but there comes a rapid adaptation of microorganisms, therefore there is a need to implement new products to prevent damage to roots and improve the quality of produced sugar. To resolve this problem experimentally selected bactericidal drug, defined its rational concentration and conditions for the use in sugar beet production. The use of antibacterial drug in the process of extraction allows to increase the purity of diffusion juice 1.3 %, reduce the protein content in it (12.5 %; with the purity of the pure juice increases by 1.1 %, its color index is reduced by 44.7 %.

    The demand for biofuel pellets has increased considerably in recent years, causing shortage of the traditional raw materials sawdust and wood shavings. In this study, the costs and energy requirements for the production of pellets from agricultural raw materials were analysed. The materials studied were Salix, reed canary grass, hemp, straw, screenings, rape-seed meal, rape cake and distiller's waste. Four production scales were analysed, having an annual output of 80,000, 8000, 800 and 80 tonnes of pellets per year. It was concluded that the raw materials of greatest interest were Salix and reed canary grass. They had competitive raw material costs and acceptable fuel properties and could be mixed with sawdust in existing large-scale pelleting factories. Straw had low production costs but can cause serious ash-related problems and should, as also is the case for screenings, be avoided in small-scale burners. Hemp had high raw material costs and is of less commercial interest, while distiller's waste, rape-seed meal and rape cake had higher alternative values when used as protein feed. The scale of production had a crucial influence on production costs. The machinery was used much more efficiently in large-scale plants, resulting in clear cost savings. Small-scale pelleting, both static and mobile, required cheap raw materials, low labour costs and long utilisation times to be profitable. In most cases, briquetting would be more commercially viable. The energy use in manufacturing pellets from air-dried crops was generally no higher than when moist sawdust was used as the raw material. (author)

    Historic manufacturing enterprises based on vertically optimized companies, practices, market share, and competitiveness are giving way to enterprises that are responsive across an entire value chain to demand dynamic markets and customized product value adds; increased expectations for environmental sustainability, reduced energy usage, and zero incidents; and faster technology and product adoption. Agile innovation and manufacturing combined with radically increased productivity become engines for competitiveness and reinvestment, not simply for decreased cost. A focus on agility, productivity, energy, and environmental sustainability produces opportunities that are far beyond reducing market volatility. Agility directly impacts innovation, time-to-market, and faster, broader exploration of the trade space. These changes, the forces driving them, and new network-based information technologies offering unprecedented insights and analysis are motivating the advent of smart manufacturing and new information technology infrastructure for manufacturing.

    2011-03-01

    Full Text Available The rising prevalence of obesity, not only in adults but also in children and adolescents, is one of the most important public health problems in developed and developing countries. As one possible way to tackle obesity, a great interest has been stimulated in understanding the relationship between different types of dietary carbohydrate and appetite regulation, body weight and body composition. The present article reviews the conclusions from recent reviews and meta-analyses on the effects of different starches and sugars on body weight management and metabolic disturbances, and provides an update of the most recent studies on this topic. From the literature reviewed in this paper, potential beneficial effects of intake of starchy foods, especially those containing slowly-digestible and resistant starches, and potential detrimental effects of high intakes of fructose become apparent. This supports the intake of whole grains, legumes and vegetables, which contain more appropriate sources of carbohydrates associated with reduced risk of cardiovascular and other chronic diseases, rather than foods rich in sugars, especially in the form of sugar-sweetened beverages.

    Enzymatic conversion is very important to produce functional rare sugars, but the conversion rate of single enzymes is generally low. To increase the conversion rate, a dual-enzyme coupled reaction system was developed. Dual-enzyme coupled reaction system was constructed using D-psicose-3-epimerase (DPE) and L-rhamnose isomerase (L-RhI), and used to convert D-fructose to D-psicose and D-allose. The ratio of DPE and L-RhI was 1:10 (W/W), and the concentration of DPE was 0.05 mg/mL. The optimum temperature was 60 degrees C and pH was 9.0. When the concentration of D-fructose was 2%, the reaction reached its equilibrium after 10 h, and the yield of D-psicose and D-allose was 5.12 and 2.04 g/L, respectively. Using the dual-enzymes coupled system developed in the current study, we could obtain sugar syrup containing functional rare sugar from fructose-rich raw material, such as high fructose corn syrup.

    The basic requirements for plant growth are light, CO2, water, and minerals. However, the absorption and utilization of each of these requires investment on the part of the plant. The primary products of plants are sugars, and the hexose sugars glucose and fructose are the raw material for most of the metabolic pathways and organic matter in plants. To be metabolized, hexose sugars must first be phosphorylated. Only two families of enzymes capable of catalysing the essential irreversible phosphorylation of glucose and fructose have been identified in plants, hexokinases (HXKs) and fructokinases (FRKs). These hexose-phosphorylating enzymes appear to coordinate sugar production with the abilities to absorb light, CO2, water, and minerals. This review describes the long- and short-term effects mediated by HXK and FRK in various tissues, as well as the role of these enzymes in the coordination of sugar production with the absorption of light, CO2, water, and minerals.

    Full Text Available The unique set of physical and chemical properties of asbestos has led to its many industrial applications, such as roof coverings, textiles, rope, cord and yarn, paper, friction and composition materials, household product, acid-resistant filters, packing, insulation, and certain types of lagging, amongst others. In Poland asbestos-containing products were manufactured from raw materials imported mainly from the former Soviet Union, with production launched at the beginning of 20th century. According to Annex 4 to the Act of 19 June 1997 on the prohibition of the use of asbestos-containing products, there were 28 asbestos manufacturing plants in Poland located in 11 provinces throughout the country. The current survey was undertaken to enable asbestos manufacturing plants to be arranged, described and divided in order to contribute to further surveys.

  5. The ultrasound-assisted sugar extraction from sugar beet cossettes

    2005-01-01

    The aim of this work was to study the ultrasound-assisted water extraction of sugar from sugar beet cossettes. The ultrasound bath device (25 kHz, 200 W) was used. The sonication accelerated sugar diffusion at both temperatures 18 deg C and 77.6 deg C and gave the higher level of dry matter content SS (4-6 percent) and sugar content CK (7-22 percent) in juice. The SS and CK depended on time of exposition, time and temperature of extraction. In particular, the effects of 5 min ultrasound-assisted extraction were equal to 20 min extraction in traditional conditions. The shorter time, lower temperature, higher efficiency and purity of juice could be the effects of sugar extraction with ultrasound. The change of thickness of diffusion membrane, microflows in tissue as well as it's environment caused by ultrasound was the reason of acceleration of sugar extraction

  6. Free Sugar Profile in Cycads

    Thomas Edward Marler

    2014-10-01

    Full Text Available The sugars fructose, glucose, maltose, and sucrose were quantified in seven tissues of Zamia muricata Willd. to determine their distribution throughout various organs of a model cycad species, and in lateral structural roots of 18 cycad species to determine the variation in sugar concentration and composition among species representing every cycad genus. Taproot and lateral structural roots contained more sugars than leaf, stem, female strobilus, or coralloid roots. For example, taproot sugar concentration was 6.4-fold greater than stem sugar concentration. The dominant root sugars were glucose and fructose, and the only detected stem sugar was sucrose. Sucrose also dominated the sugar profile for leaflet and coralloid root tissue, and fructose was the dominant sugar in female strobilus tissue. Maltose was a minor constituent of taproot, leaflet, and female strobilus tissue, but absent in other tissues. The concentration of total free sugars and each of the four sugars did not differ among genera or families. Stoichiometric relationships among the sugars, such as the quotient hexoses/disaccharides, differed among organs and families. Although anecdotal reports on cycad starch have been abundant due to its historical use as human food and the voluminous medical research invested into cycad neurotoxins, this is the first report on the sugar component of the non-structural carbohydrate profile of cycads. Fructose, glucose, and sucrose are abundant in cycad tissues, with their relative abundance highly contrasting among organs. Their importance as forms of carbon storage, messengers of information, or regulators of cycad metabolism have not been determined to date.

    A challenge facing the biofuel industry is to develop an economically viable and sustainable biorefinery. The existing potential biorefineries in Louisiana, raw sugar mills, operate only 3 months of the year. For year-round operation, they must adopt other feedstocks, besides sugar cane, as supplemental feedstocks. Energy cane and sweet sorghum have different harvest times, but can be processed for bio-ethanol using the same equipment. Juice of energy cane contains 9.8% fermentable sugars and that of sweet sorghum, 11.8%. Chemical composition of sugar cane bagasse was determined to be 42% cellulose, 25% hemicellulose, and 20% lignin, and that of energy cane was 43% cellulose, 24% hemicellulose, and 22% lignin. Sweet sorghum was 45% cellulose, 27% hemicellulose, and 21% lignin. Theoretical ethanol yields would be 3,609 kg per ha from sugar cane, 12,938 kg per ha from energy cane, and 5,804 kg per ha from sweet sorghum.

    The aim of the present study was to investigate the sensory attributes, dry matter and sugar content of five varieties of Jerusalem artichoke tubers and their relation to the appropriateness of the tubers for raw and boiled preparation. Sensory evaluation of raw and boiled Jerusalem artichoke tubers was performed by a trained sensory panel and a semi-trained consumer panel of 49 participants, who also evaluated the appropriateness of the tubers for raw and boiled preparation. The appropriateness of raw Jerusalem artichoke tubers was related to Jerusalem artichoke flavour, green nut flavour, sweetness and colour intensity, whereas the appropriateness of boiled tubers was related to celeriac aroma, sweet aroma, sweetness and colour intensity. In both preparations the variety Dwarf stood out from the others by being the least appropriate tuber. A few sensory attributes can be used as predictors of the appropriateness of Jerusalem artichoke tubers for raw and boiled consumption. Knowledge on the quality of raw and boiled Jerusalem artichoke tubers can be used to inform consumers on the right choice of raw material and thereby increase the consumption of the vegetable. © 2012 Society of Chemical Industry.

  2. Hot-melt extrusion of sugar-starch-pellets.

    Science.gov (United States)

    Yeung, Chi-Wah; Rein, Hubert

    2015-09-30

    Sugar-starch-pellets (syn. sugar spheres) are usually manufactured through fluidized bed granulation or wet extrusion techniques. This paper introduces hot-melt extrusion (HME) as an alternative method to manufacture sugar-starch-pellets. A twin-screw extruder coupled with a Leistritz Micro Pelletizer (LMP) cutting machine was utilized for the extrusion of different types (normal-, waxy-, and high-amlyose) of corn starch, blended with varying amounts of sucrose. Pellets were characterized for their physicochemical properties including crystallinity, particle size distribution, tensile strength, and swelling expansion. Furthermore, the influence of sugar content and humidity on the product was investigated. Both sucrose and water lowered the Tg of the starch system allowing a convenient extrusion process. Mechanical strength and swelling behavior could be associated with varying amylose and amylopectin. X-ray powder diffractometric (XRPD) peaks of increasing sucrose contents appeared above 30%. This signified the oversaturation of the extruded starch matrix system with sucrose. Otherwise, had the dissolved sucrose been embedded into the molten starch matrix, no crystalline peak could have been recognized. The replacement of starch with sucrose reduced the starch pellets' swelling effect, which resulted in less sectional expansion (SEI) and changed the surface appearance. Further, a nearly equal tensile strength could be detected for sugar spheres with more than 40% sucrose. This observation stands in good relation with the analyzed values of the commercial pellets. Both techniques (fluidized bed and HME) allowed a high yield of spherical pellets (less friability) for further layering processes. Thermal influence on the sugar-starch system is still an obstacle to be controlled. Copyright © 2015 Elsevier B.V. All rights reserved.

    Full Text Available The somatic cell count (SCC and total bacterial count (TBC as well as the presence of major food-borne pathogens and udder pathogens in reindeer raw milk were studied. Two groups of 4 female reindeer were milked on alternate days for six weeks. A milk sample from each quarter was taken before milking and of the bulk milk at the end of milking. Micrococcus sp. was observed in one, Staphylococcus aureus in one and coagulase-negative staphylococci in five of the quarter samples (n=318. In the bulk milk (n=19 TBC varied between 700 and 1 700 000 cfu (colony forming units/ml and SCC between 52 000 and 183 000 cells/ml. No Bacillus cereus, S. aureus or Listeria monocytogenes were detected in the bulk milk, but Escherichia coli and Enterobacteriaceae were found in 5 bulk milk samples. According to the bacteriological examination the udder health of the reindeer was good. Indicative information on the SCC of healthy reindeer was obtained. None of the common potential food-poisoning bacteria were found in raw milk. There was great variation in the bulk milk TBC and the average TBC was rather high (ca. 300 000 cfu/ml. The hygienic quality of raw reindeer milk makes it well suited for food manufacture. However, the results indicate that the milking conditions may be crucial for the quality of raw milk.Abstract in Finnish / Yhteenveto:Tutkimuksen kohteena oli poron raakamaidon solupitoisuus ja kokonaispesäkeluku sekä tärkeimpien elintarvike- ja utarepatogeenien esiintyminen raakamaidossa.

    End-users and OEM's using or manufacturing on/off and control valves expect a permanent and effective increase in service life together with an increased sealing capability while at the same time minimizing maintenance concerns. Developing materials which provide consistency and repeatability are essential characteristics to optimizing valve performance. “New Generation” materials and yarn allow us to meet this growing demand while complying with the requirements related to chemical purity and an increased level of safety to both plant workers and equipment in the nuclear environment. Through R&D initiatives and developments in new and improved raw materials; a new mechanical packing generation which optimizes friction coefficients and extended life cycle has been introduced to the industry. Lower friction values drastically optimize actuator effort and size improving efficiency for stem operation with significant improvements in flow control of fluids. Combined with new and improved procedures (installation, torque levels and consolidation recommendations), this new packing generation has provided significant improvement in the mechanical behavior of packing materials (independent tests carried out in collaboration with AECL and CETIM) this has provided the opportunity to develop successful Valve Enhancement Programs which offer improved efficiency, valve operation and repeatability. These NEW generation yarns are available with or without wire reinforcement depending on specific operating parameters and conditions. The purpose of this presentation is to demonstrate that new generation material(s). Which are available to the industry for AOV, MOV and Manual valves? - To highlight the steps taken in R&D and manufacturing contributing to the much improved yarns and finished packing products. - Comply and are designed to meet the stringent requirements in the nuclear industry - Simplify valve maintenance without risk to safety or performance - Increase service

    Description is given of a method for manufacturing monocrystals, substantially free of disorder, of a metal showing an allotropic transformation at a temperature lower than its melting point. Monocrystals of the raw metal having undergone a uni-directional solidification are heated to a temperature between the allotropic transformation point and the metal melting point; the monocrystals are maintained in the vicinity of that temperature for a given period of time; they are cooled down to a temperature lower than the allotropic transformation point, then they are annealed and cooled down to room temperature. Such monocrystals are used in neutron monochromators [fr

    In order to enlight the strange problem of apparent perfume stability observed in manufactured talc powders sterilized by gamma rays, investigations were made on samples of odorant substances (raw materials, essential oils, or elaborated mixtures). As a rule, no immediate adulteration of olfactive caracteristics resulted at once from gamma irradiation. In several cases, a stabilizing effect appeared immediately and remained effective after long storage in various conditions (of temperature, or light, or oxygen exposure). This unexpected effect seems to be in accordance with previous experiments on gamma or electron irradiations of mixtures of organic molecules, reported in litterature: a mutual inhibition was observed to take place [fr

    Biorefinery of sugar cane is the first economic activity of Reunion Island. Some sugar cane manufactured products (juice, syrup, molasses) have antioxidant activities and are sources of both phenolic compounds and Maillard Reaction Products (MRP). The study aimed to highlight the global antioxidant activity of sugar cane stillage and understand its identity. Chromatographic fractionation on Sephadex LH-20 resin allowed the recovery of a MRP-rich fraction, responsible for 58 to 66% of the global antioxidant activity according to the nature of the sugar cane stillage (DPPH test), and a phenolic compounds-rich fraction for 37 to 59% of the activity. A good correlation was recorded between the antioxidant activity of the sugar cane stillage and its content in total reducing compounds amount (Folin-Ciocalteu assay), among them 2.8 to 3.9 g/L of phenolic compounds (in 5-caffeoylquinic acid equivalent). Preliminary experiments by HPLC-DAD-MS allowed to identify several free phenolic acids and gave clues to identify esters of quinic acids.

  16. Identification of Particles in Parenteral Drug Raw Materials.

    Lee, Kathryn; Lankers, Markus; Valet, Oliver

    2018-04-18

    Particles in drug products are not good and are therefore regulated. These particles can come from the very beginning of the manufacturing process, from the raw materials. To prevent particles, it is important to understand what they are and where they come from so the raw material quality, processing, and shipping can be improved. Thus, it is important to correctly identify particles seen in raw materials. Raw materials need to be of a certain quality with respect to physical and chemical composition, and need to have no contaminants in the form of particles which could contaminate the product or indicate the raw materials are not pure enough to make a good quality product. Particles are often seen when handling raw materials due to color, size, or shape characteristics different from those in the raw materials. Particles may appear to the eye to be very different things than they actually are, so microscope, chemical, and elemental analyses are required for accuracy in proper identification. This paper shows how using three different spectroscopy tools correctly and together can be used to identify particles from extrinsic, intrinsic, and inherent particles. Sources of materials can be humans and the environment (extrinsic), from within the process (intrinsic), and part of the formulation (inherent). Microscope versions of Raman spectroscopy, laser-induced breakdown spectroscopy (LIBS), and IR spectroscopy are excellent tools for identifying particles because they are fast and accurate techniques needing minimal sample preparation that can provide chemical composition as well as images that can be used for identification. The micro analysis capabilities allow for easy analysis of different portions of samples so multiple components can be identified and sample preparation can be reduced. Using just one of these techniques may not be sufficient to give adequate identification results so that the source of contamination can be adequately identified. The

    The paper manufacturing companies are facing challenges to implement sustainable manufacturing into their products and processes. Paper manufacturing has remarked as an intensive consumer of natural raw materials, energy and a major source of multiple pollutants. Thus, evaluating the sustainable manufacturing in these companies has become a necessity. This paper proposes a set of Performance Indicators (PIs) for evaluating the sustainable manufacturing appropriate to the paper manufacturing companies based on the triple bottom line of sustainability. The Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS), a multi-criteria decision analysis method is applied to prioritize the performance indicators by summarizing the opinions of stakeholders. It is hoped that the proposed PIs enables and assists the paper manufacturing companies to achieve the higher performance in sustainable manufacturing and so as to increase their competitiveness.

    2008-10-01

    The occurrence of Campylobacter spp. in a variety of foods from Ottawa, Ontario, Canada, and raw milk samples from across Canada was determined over a 2-year period. The samples consisted of 55 raw foods (chicken, pork, and beef), 126 raw milk samples from raw milk cheese manufacturers, and 135 ready-to-eat foods (meat products, salads, and raw milk cheeses). Campylobacter jejuni was detected in 4 of the 316 samples analyzed: 1 raw beef liver sample and 3 raw chicken samples. An isolation rate of 9.7% was observed among the raw chicken samples tested. This study also investigated the role of cross-contamination in disseminating Campylobacter from raw poultry within a food service operation specializing in poultry dishes. Accordingly, kitchen surfaces within a restaurant in Ottawa, Ontario, were sampled between March and August 2001. Tests of the sampling method indicated that as few as 100 Campylobacter cells could be detected if sampling was done within 45 min of inoculation; however, Campylobacter spp. were not detected in 125 swabs of surfaces within the kitchens of this food service operation. Despite the reported high prevalence of Campylobacter spp. in raw poultry, this organism was not detected on surfaces within a kitchen of a restaurant specializing in poultry dishes.

    The Additive Manufacturing (AM) processes open the possibility to go directly from Computer-Aided Design (CAD) to a physical prototype. These prototypes are used as test models before it is finalized as well as sometimes as a final product. Additive Manufacturing has many advantages over the traditional process used to develop a product such as allowing early customer involvement in product development, complex shape generation and also save time as well as money. Additive manufacturing also possess some special challenges that are usually worth overcoming such as Poor Surface quality, Physical Properties and use of specific raw material for manufacturing. To improve the surface quality several attempts had been made by controlling various process parameters of Additive manufacturing and also applying different post processing techniques on components manufactured by Additive manufacturing. The main objective of this work is to document an extensive literature review in the general area of post processing techniques which are used in Additive manufacturing.

    While demand for pulp and paper products in India is increasing at the annual rate of 7 to 8%, availability of cellulosic raw material to meet the ever increasing demand is becoming a serious problem. It has been estimated that bamboo, the traditional source of cellulosic raw material in India, even after ensuring the most scientific and best possible exploitation, could provide less than 50% of the requirement. In a big agricultural country like India, agri-residues like straws and bagasse, along with jute sticks, available in huge quantity, could provide substantial amount of cellulosic resources to the pulp and paper industry. Realizing the importance of agri-residue utilization in Indian economy, a series of research projects have been initiated and completed during the last 15 years to study the techno-economic feasibility of manufacturing pulp, paper, and industrial chemicals, based on rice and wheat straws, bagasse, and jute sticks. The economic advantages of the mechano-chemical pulping process, as compared to the conventional pressure, pulping process, for the conversion of agri-residues into pulp and paer is evaluated. For highlighting the importance of agri-residues in the field of useful chemical recovery possibilities, experimental data are given on the saccarification of agri-residues into reducing sugars by the simple acid hydrolysis method with the help of concentrated sulfuric acid.

    Full Text Available We address an important problem of a manufacturing system. The system procures raw materials from outside suppliers in a lot and processes them to produce finished goods. It proposes an ordering policy for raw materials to meet the requirements of a production facility. In return, this facility has to deliver finished products demanded by external buyers at fixed time intervals. First, a general cost model is developed considering both raw materials and finished products. Then this model is used to develop a simulated annealing approach to determining an optimal ordering policy for procurement of raw materials and also for the manufacturing batch size to minimize the total cost for meeting customer demands in time. The solutions obtained were compared with those of traditional approaches. Numerical examples are presented. .

    2012-01-01

    Understanding variability in raw materials and their impacts on product quality is of critical importance in the biopharmaceutical manufacturing processes. For this purpose, several spectroscopic techniques have been studied for raw material characterization, providing fast and nondestructive ways to measure quality of raw materials. However, investigations of correlation between spectra of raw materials and cell culture performance have been scarce due to their complexity and uncertainty. In this study, near-infrared spectra and bioassays of multiple soy hydrolysate lots manufactured by different vendors were analyzed using chemometrics approaches in order to address variability of raw materials as well as correlation between raw material properties and corresponding cell culture performance. Principal component analysis revealed that near-infrared spectra of different soy lots contain enough physicochemical information about soy hydrolysates to allow identification of lot-to-lot variability as well as vendor-to-vendor differences. The identified compositional variability was further analyzed in order to estimate cell growth and protein production of two mammalian cell lines under the condition of varying soy dosages using partial least square regression combined with optimal variable selection. The performance of the resulting models demonstrates the potential of near-infrared spectroscopy as a robust lot selection tool for raw materials while providing a biological link between chemical composition of raw materials and cell culture performance.

  12. Sugar Price Supports and Taxation

    Dilk, Abby; Savaiano, Dennis A.

    2017-01-01

    Domestic US sugar production has been protected by government policy for the past 82 years, resulting in elevated domestic prices and an estimated annual (2013) $1.4 billion dollar “tax” on consumers. These elevated prices and the simultaneous federal support for domestic corn production have ensured a strong market for high-fructose corn syrup. Americans have dramatically increased their consumption of caloric sweeteners during the same period. Consumption of “empty” calories (ie, foods with low-nutrient/high-caloric density)—sugar and high-fructose corn syrup being the primary sources—is considered by most public health experts to be a key contributing factor to the rise in obesity. There have been substantial efforts to tax sugar-sweetened beverages (SSBs) to both reduce consumption and provide a source of funds for nutrition education, thereby emulating the tobacco tax model. Volume-based SSB taxes levy the tax rate per ounce of liquid, where some are only imposed on beverages with added sugar content exceeding a set threshold. Nonetheless, volume-based taxes have significant limitations in encouraging consumers to reduce their caloric intake due to a lack of transparency at the point of purchase. Thus, it is hypothesized that point-of-purchase, nutrient-specific excise taxes on SSBs would be more effective at reducing sugar consumption. However, all SSB taxes are limited by the possibility that consumers may compensate their decreased intake from SSBs with other high-calorie junk foods. Furthermore, there are no existing studies to provide evidence on how SSB taxes will impact obesity rates in the long term. The paradox of sugar prices is that Americans have paid higher prices for sugar to protect domestic production for more than 80 years, and now, Americans are being asked to pay even more to promote public health. The effective use of sugar taxes should be considered based on their merits in reducing sugar consumption and making available a new

    Malrotation with a common mesentery is the classical pathology allowing midgut volvulus to occur. There are only a few reports of small bowel volvulus without malrotation or other pathology triggering volvulation. We describe three cases of small bowel volvulus in very premature newborns with a perfectly normal intra-abdominal anatomy and focus on the question, what might have set off volvulation. In 2005 to 2008, three patients developed small bowel volvulus without any underlying pathology. Retrospective patient chart review was performed with special focus on clinical presentation, preoperative management, intraoperative findings, and potential causative explanations. Mean follow-up period was 46 months. All patients were born between 27 and 31 weeks (mean 28 weeks) with a birth weight between 800 and 1,000 g (mean 887 g). They presented with an almost identical pattern of symptoms including sudden abdominal distension, abdominal tenderness, erythema of the abdominal wall, high gastric residuals, and radiographic signs of ileus. All of them were treated with intensive abdominal massage or pelvic rotation to improve bowel movement before becoming symptomatic. Properistaltic maneuvers including abdominal massage and pelvic rotation may cause what we term a "manufactured" volvulus in very premature newborns. Thus, this practice was stopped.

    The invention includes a method of dehydration of a sugar using a dehydration catalyst and a co-catalyst within a reactor. A sugar is introduced and H.sub.2 is flowed through the reactor at a pressure of less than or equal to about 300 psig to convert at least some of the sugar into an anhydrosugar product. The invention includes a process for producing isosorbide. A starting material comprising sorbitol is flowed into a reactor. H.sub.2 is counter flowed through the reactor. The starting material is exposed to a catalyst in the presence of a co-catalyst which comprises at least one metal. The exposing is conducted at a hydrogen pressure of less than or equal to 300 psig within the reactor and the hydrogen removes at least some of any water present during the exposing and inhibits formation of colored byproducts.

    In this paper the use of coal, found at Jabba Taar and Jabba Khushk Khyber Pakhtoon Khwa, in cement manufacturing as a major fuel and its impacts on the raw mix and clinker parameters has been discussed. The maximum amount of coal for pulverizing with raw mix was found to be 10% of the raw mix as calculated from the calorific value and the heat of clinkerization of coal. The coal residue left after burning was utilized in the cement raw material, for which a new raw mix was designed. The new raw mix was converted in to clinker. The resulting clinker was studied for all parameters as per British specification. It was found that the clinker obtained from the newly designed raw mix with coal ash, was in accordance to the British standard specifications. (author)

    Chimpanzee termite fishing has been studied for decades, yet the selective processes preceding the manufacture of fishing tools remain largely unexplored. We investigate raw material selection and potential evidence of forward planning in the chimpanzees of Issa valley, western Tanzania. Using traditional archaeological methods, we surveyed the location of plants from where chimpanzees sourced raw material to manufacture termite fishing tools, relative to targeted mounds. We measured raw material abundance to test for availability and selection. Statistics included Chi-Squared, two-tailed Wilcoxon, and Kruskall-Wallace tests. Issa chimpanzees manufactured extraction tools only from bark, despite availability of other suitable materials (e.g., twigs), and selected particular plant species as raw material sources, which they often also exploit for food. Most plants were sourced 1-16 m away from the mound, with a maximum of 33 m. The line of sight from the targeted mound was obscured for a quarter of these plants. The exclusive use of bark tools despite availability of other suitable materials indicates a possible cultural preference. The fact that Issa chimpanzees select specific plant species and travel some distance to source them suggests some degree of selectivity and, potentially, forward planning. Our results have implications for the reconstruction of early hominin behaviors, particularly with regard to the use of perishable tools, which remain archaeologically invisible. © 2017 Wiley Periodicals, Inc.

    Analytical tools that accurately predict the performance of raw milk following its manufacture into commercial food products are of economic interest to the dairy industry. To evaluate the ability of currently applied raw milk microbiological tests to predict the quality of commercially pasteurized fluid milk products, samples of raw milk and 2% fat pasteurized milk were obtained from 4 New York State fluid milk processors for a 1-yr period. Raw milk samples were examined using a variety of tests commonly applied to raw milk, including somatic cell count, standard plate count, psychrotrophic bacteria count, ropy milk test, coliform count, preliminary incubation count, laboratory pasteurization count, and spore pasteurization count. Differential and selective media were used to identify groups of bacteria present in raw milk. Pasteurized milk samples were held at 6°C for 21 d and evaluated for standard plate count, coliform count, and sensory quality throughout shelf-life. Bacterial isolates from select raw and pasteurized milk tests were identified using 16S ribosomal DNA sequencing. Linear regression analysis of raw milk test results versus results reflecting pasteurized milk quality consistently showed low R(2) values (tests and results from tests used to evaluate pasteurized milk quality. Our findings suggest the need for new raw milk tests that measure the specific biological barriers that limit shelf-life and quality of fluid milk products.

  10. Synthesis of the Sugar Moieties

    Science.gov (United States)

    Grynkiewicz, Grzegorz; Szeja, Wieslaw

    Biological activity of the anthracycline antibiotics, which have found wide application in clinical oncology, is strongly related to their glycosidic structure. Modification or switch of the saccharide moiety became an important line of new drug discovery and study of their mechanism of action. Natural glycons (sugar moieties) of the anthracycline antibiotics belong to the 2,6-dideoxypyranose family and their principal representative, daunosamine, is 3-amino-2,3,6-trideoxy- l-lyxo-pyranose. Some newer chemical syntheses of this sugar, from a chiral pool as well as from achiral starting materials, are presented and their capability for scale-up and process development are commented upon. Rational sugar structural modifications, which are either useful for synthetic purposes or offer advantages in experimental therapy of cancer, are discussed from the chemical point of view.

    Estimating trends in dietary intake data is integral to informing national nutrition policy and monitoring progress towards dietary guidelines. Dietary intake of sugars is a controversial public health issue and guidance in relation to recommended intakes is particularly inconsistent. Published data relating to trends in sugars intake are relatively sparse. The purpose of the present review was to collate and review data from national nutrition surveys to examine changes and trends in dietary sugars intake. Only thirteen countries (all in the developed world) appear to report estimates of sugars intake from national nutrition surveys at more than one point in time. Definitions of dietary sugars that were used include 'total sugars', 'non-milk extrinsic sugars', 'added sugars', sucrose' and 'mono- and disaccharides'. This variability in terminology across countries meant that comparisons were limited to within countries. Hence trends in dietary sugars intake were examined by country for the whole population (where data permitted), and for specific or combined age and sex subpopulations. Findings indicate that in the majority of population comparisons, estimated dietary sugars intake is either stable or decreasing in both absolute (g/d) and relative (% energy) terms. An increase in sugars intake was observed in few countries and only in specific subpopulations. In conclusion, the findings from the present review suggest that, in the main, dietary sugars intake are decreasing or stable. A consistent approach to estimation of dietary sugars intake from national nutrition surveys is required if more valid estimates of changes in dietary sugars intakes are required in the future.

    2013-01-01

    The EU imports both bioethanol and the raw material needed to produce it. Thirty percent of bioethanol is produced from sugar beets in the EU. However, sugar beet cultivated area and yields have fallen due to the 2006 sugar regime reform. Given the potential uncertainty about the future for sugar beet farmers, biofuels may represent an alternative market. This paper analyses potential contribution to the efficiency, in terms of environmental output, of the sugar beet crop both when production is oriented toward bioethanol and regarding the use of input. An empirical application is performed in Spain by Data Envelopment Analysis (DEA). The results show that 4% of farms have full technical efficiency, while the rest have an average efficiency of 55.9%. The figures show that inputs can be reduced over 40%, and also show the low average level of input-use efficiency. In addition, it cannot be said that there is a relationship between efficiency and farm scale. The consideration of aspects such as the environmental advantages of using sugar beet production for bioethanol can open new lines of action to support this crop in the EU. In addition, boosting sugar beet production may reduce potential dependency on importation. - Highlights: ► Analysing environmental outputs from agricultural input use and production orientation to bioethanol. ► DEA is applied to model farms’ efficiency in GHG emission and nitrous oxides emissions. ► A very low level of efficiency is found in sugar beet farms. ► Efficiency increase should be supported to reduce fertilizers and pesticides. ► Environmental advantages of addressing sugar beet to bioethanol open new lines to support crops

  18. Pyrolytic sugars from cellulosic biomass

    Science.gov (United States)

    Kuzhiyil, Najeeb

    Sugars are the feedstocks for many promising advanced cellulosic biofuels. Traditional sugars derived from starch and sugar crops are limited in their availability. In principle, more plentiful supply of sugars can be obtained from depolymerization of cellulose, the most abundant form of biomass in the world. Breaking the glycosidic bonds between the pyranose rings in the cellulose chain to liberate glucose has usually been pursued by enzymatic hydrolysis although a purely thermal depolymerization route to sugars is also possible. Fast pyrolysis of pure cellulose yields primarily levoglucosan, an anhydrosugar that can be hydrolyzed to glucose. However, naturally occurring alkali and alkaline earth metals (AAEM) in biomass are strongly catalytic toward ring-breaking reactions that favor formation of light oxygenates over anhydrosugars. Removing the AAEM by washing was shown to be effective in increasing the yield of anhydrosugars; but this process involves removal of large amount of water from biomass that renders it energy intensive and thereby impractical. In this work passivation of the AAEM (making them less active or inactive) using mineral acid infusion was explored that will increase the yield of anhydrosugars from fast pyrolysis of biomass. Mineral acid infusion was tried by previous researchers, but the possibility of chemical reactions between infused acid and AAEM in the biomass appears to have been overlooked, possibly because metal cations might be expected to already be substantially complexed to chlorine or other strong anions that are found in biomass. Likewise, it appears that previous researchers assumed that as long as AAEM cations were in the biomass, they would be catalytically active regardless of the nature of their complexion with anions. On the contrary, we hypothesized that AAEM can be converted to inactive or less active salts using mineral acids. Various biomass feedstocks were infused with mineral (hydrochloric, nitric, sulfuric and

  19. Aromatic raw materials from coal

    Energy Technology Data Exchange (ETDEWEB)

    Collin, G

    1982-06-01

    Liquid byproducts of coal carbonization meet some 25% of the world demand for aromatic chemicals, currently at approx. 30 million t/a, in particular 15% of the demand for benzene and over 95% of the demand for condensed aromatics and heteroaromatics. Industrial processing of the aromatic byproducts of coal pressure gasification is carried out to only a minor extent. Other methods that may be employed in future to obtain carbochemical aromatic compounds are solvolysis and supercritical gas extraction, the catalytic liquid-phase hydrogenation and hydropyrolysis of coal, which also permit recovery of benzene and homologues, phenols, and condensed and partially hydrogenated aromatics, and the synthesis of aromatics using methanol as the key compound. As with the present means of obtaining aromatic chemicals from coal, the processes that may in future be applied on an industrial scale to obtain pure aromatics will only be economically feasible if linked with the manufacture of other mass products and combined with the present production of carbochemical aromatics.

    Reflections on prospective mineral raw materials and materials must rest upon the expected demographic evolution, the evaluation of economic development and the development of manufacturing technologies and materials corresponding to them, trends in the consumption of mineral raw materials and possibilities of securing them. The evaluation of the given factors under conditions of the Czech Republic shows that one of the decisive prerequisites to transforming the Czech economy is to assure the fuel and energy security of the state. In addition to emphasis put on traditional and newly developed technologies of utilization of domestic resources of coal and the development of nuclear power, a diversification of supplies of oil and gas is necessary. Moreover, it is necessary to ensure domestic resources of raw materials to some prospective material areas, or to provide these raw materials by means of imports and/or entrepreneurial activity abroad. As far as raw materials for building and industrial rocks are concerned, it is necessary to support the exploitation and home utilization through laws and suitable economic tools at respecting environmental limitations. With non-traditional prospective raw materials, it will be desirable to promote exploration and mining especially in those cases when a precondition exists for the securing of sufficient reserves or when reserves are already known

  5. Manufacturing fuel-switching capability, 1988

    International Nuclear Information System (INIS)

    1991-09-01

    Historically, about one-third of all energy consumed in the United States has been used by manufacturers. About one-quarter of manufacturing energy is used as feedstocks and raw material inputs that are converted into nonenergy products; the remainder is used for its energy content. During 1988, the most recent year for which data are available, manufacturers consumed 15.5 quadrillion British thermal units (Btu) of energy to produce heat and power and to generate electricity. The manufacturing sector also has widespread capabilities to switch from one fuel to another for either economic or emergency reasons. There are numerous ways to define fuel switching. For the purposes of the Manufacturing Energy Consumption Survey (MECS), fuel switching is defined as the capability to substitute one energy source for another within 30 days with no significant modifications to the fuel-consuming equipment, while keeping production constant. Fuel-switching capability allows manufacturers substantial flexibility in choosing their mix of energy sources. The consumption of a given energy source can be maximized if all possible switching into that energy source takes place. The estimates in this report are based on data collected on the 1988 Manufacturing Energy Consumption Survey (MECS), Forms 846 (A through C). The EIA conducts this national sample survey of manufacturing energy consumption on a triennial basis. The MECS is the only comprehensive source of national-level data on energy-related information for the manufacturing industries. The MECS was first conducted in 1986 to collect data for 1985. This report presents information on the fuel-switching capabilities of manufacturers in 1988. This report is the second of a series based on the 1988 MECS. 8 figs., 31 tabs

Various BAILs were synthesized and characterized using NMR, FT-IR, TGA, and CHNS microanalysis and were used as the catalyst for raw biomass conversion. The remarkably high yield (i.e. 88%) of C5 sugars from bagasse can be obtained using 1-methyl-3(3-sulfopropyl)-imidazolium hydrogen sulfate ([C 3 SO 3 HMIM][HSO 4 ]) BAIL catalyst in a water medium. Similarly, the [C 3 SO 3 HMIM][HSO 4 ] BAIL also converts the bagasse into furfural with very high yield (73%) in one-pot method using a water/toluene biphasic solvent system.

  8. A Spoonful of (Added) Sugar Helps the Constitution Go Down: Curing the Compelled Speech Commercial Speech Doctrine with FDA’s Added Sugars Rule.

    Science.gov (United States)

    Smith, Colleen

    On May 27, 2016, the Food and Drug Administration (FDA) announced that it was adopting a new rule that requires food manufacturers to list—on the already mandated Nutrition Facts label—how many grams of sugar have been added to a food product. Many opponents have criticized this “added sugars” rule on First Amendment grounds, arguing that the rule violates the commercial speech rights of food manufacturers. Whether the rule would survive constitutional scrutiny or not is an open question because the compelled commercial speech doctrine is anything but clear. Courts are split over whether Zauderer’s rational basis test, Central Hudson’s intermediate scrutiny, or some combination of the two should apply to a mandated disclosure like FDA’s added sugars rule. This Paper explains that the added sugars rule is unique in the history of mandated nutrition labeling in that the rule is motivated largely by public health concerns and backed by reports that assert that consumers should limit their intake of added sugars. In contrast, correcting and preventing consumer deception has been a major driving force behind the remainder of FDA’s mandated nutrition labeling. Because of this distinct rationale, the added sugars rule does not fit neatly into any currently existing compelled commercial speech test. This Paper uses the added sugars rule to highlight the deficiencies in the existing tests. Finally, this Paper proposes a new compelled commercial speech test that would adequately balance the interest of all of the effected parties: the government, the public, and food manufacturers.

  15. Influence of raw milk quality on processed dairy products: How do raw milk quality test results relate to product quality and yield?

    Science.gov (United States)

    Murphy, Steven C; Martin, Nicole H; Barbano, David M; Wiedmann, Martin

    2016-12-01

    This article provides an overview of the influence of raw milk quality on the quality of processed dairy products and offers a perspective on the merits of investing in quality. Dairy farmers are frequently offered monetary premium incentives to provide high-quality milk to processors. These incentives are most often based on raw milk somatic cell and bacteria count levels well below the regulatory public health-based limits. Justification for these incentive payments can be based on improved processed product quality and manufacturing efficiencies that provide the processor with a return on their investment for high-quality raw milk. In some cases, this return on investment is difficult to measure. Raw milks with high levels of somatic cells and bacteria are associated with increased enzyme activity that can result in product defects. Use of raw milk with somatic cell counts >100,000cells/mL has been shown to reduce cheese yields, and higher levels, generally >400,000 cells/mL, have been associated with textural and flavor defects in cheese and other products. Although most research indicates that fairly high total bacteria counts (>1,000,000 cfu/mL) in raw milk are needed to cause defects in most processed dairy products, receiving high-quality milk from the farm allows some flexibility for handling raw milk, which can increase efficiencies and reduce the risk of raw milk reaching bacterial levels of concern. Monitoring total bacterial numbers in regard to raw milk quality is imperative, but determining levels of specific types of bacteria present has gained increasing importance. For example, spores of certain spore-forming bacteria present in raw milk at very low levels (e.g., products to levels that result in defects. With the exception of meeting product specifications often required for milk powders, testing for specific spore-forming groups is currently not used in quality incentive programs in the United States but is used in other countries (e.g., the

    2016-07-01

    Full Text Available Basic raw materials belong to the key input sources in the production of pig iron. The properties of basic raw materials can be evaluated using a variety of criteria. The essential ones include the physical and chemical properties. Current competitive pressures, however, force the producers of iron more and more often to include cost and logistic criteria into the decision-making process. In this area, however, they are facing a problem of how to convert a variety of vastly different parameters into one evaluation indicator in order to compare the available raw materials. This article deals with the analysis of a model created to evaluate the basic raw materials, which was designed as part of the research.

  1. The UK sugar tax - a healthy start?

    Science.gov (United States)

    Jones, C M

    2016-07-22

    The unexpected announcement by the UK Chancellor of the Exchequer of a levy on sugar sweetened beverages (SSBs) on the 16 March 2016, should be welcomed by all health professionals. This population based, structural intervention sends a strong message that there is no place for carbonated drinks, neither sugared nor sugar-free, in a healthy diet and the proposed levy has the potential to contribute to both general and dental health. The sugar content of drinks exempt from the proposed sugar levy will still cause tooth decay. Improving the proposed tax could involve a change to a scaled volumetric tax of added sugar with a lower exemption threshold. External influences such as the Common Agricultural Policy and the Transatlantic Trade and Investment Partnership may negate the benefits of the sugar levy unless it is improved. However, the proposed UK sugar tax should be considered as a start in improving the nation's diet.

  10. High energy beam manufacturing technologies

    International Nuclear Information System (INIS)

    Geskin, E.S.; Leu, M.C.

    1989-01-01

    Technological progress continues to enable us to utilize ever widening ranges of physical and chemical conditions for material processing. The increasing cost of energy, raw materials and environmental control make implementation of advanced technologies inevitable. One of the principal avenues in the development of material processing is the increase of the intensity, accuracy, flexibility and stability of energy flow to the processing site. The use of different forms of energy beams is an effective way to meet these sometimes incompatible requirements. The first important technological applications of high energy beams were welding and flame cutting. Subsequently a number of different kinds of beams have been used to solve different problems of part geometry control and improvement of surface characteristics. Properties and applications of different specific beams were subjects of a number of fundamental studies. It is important now to develop a generic theory of beam based manufacturing. The creation of a theory dealing with general principles of beam generation and beam-material interaction will enhance manufacturing science as well as practice. For example, such a theory will provide a format approach for selection and integration of different kinds of beams for a particular application. And obviously, this theory will enable us to integrate the knowledge bases of different manufacturing technologies. The War of the Worlds by H. G. Wells, as well as a number of more technical, although less exciting, publications demonstrate both the feasibility and effectiveness of the generic approach to the description of beam oriented technology. Without any attempt to compete with Wells, we still hope that this volume will contribute to the creation of the theory of beam oriented manufacturing

    1987-01-01

    The novelty of this approach was hydrolysis of the raw starch in ground corn to fermentable sugars that are simultaneously fermented to ethanol by yeast in a nonsterile environment. Thus, the conventional cooking step can be eliminated for energy conservation. A koji of Aspergillus niger grown on whole corn for 3 days was the crude enzyme source. A ratio of 0.2 g dry koji/g total solids was found sufficient. Optimum pH was 4.2. Ethanol concentration was 7.7% (w/w) in the aqueous phase with 92% raw starch conversion. Agitation increased rate. Sacharification was the rate-limiting step. The initial ethanol concentration preventing fermentation was estimated to be 8.3% by weight. (Refs. 96).

    1993-01-01

    A tropical clime culture, the sugar cane is planted mainly in underdeveloped countries, being a important economic source. The agricultural sector received during many years funds for technological development, but the sugar cane pressing system did not receive significant technical evolution since the fifties. One of the problem needs solution is the low quality of the raw material, caused by the difficulty of the reaping operation, it causes exaggerated addiction of impurities. The industrial ware down in plants and distilleries does not come exclusively from the action from mineral impurities, occurring also in the processing of pure raw material, free of soil, but is known that the great increase in ware down especially in the extraction system due to the presence of soil on the cane. Keeping the level of minerals to the minimum, makes the ware down to follow to acceptable technical and economical levels. This paper discusses the possibility of quantify the ware down of the extraction equipment by neutron activation of samples collected in one sugar cane plant. For that, the study of the behavior of the elements from sugar cane itself and soil present as impurity and the ware down of the metallic equipment. It was not possible quantify any addition of ware down elements in cane and its derivatives, by the processing system. The iron demonstrated to be a potential tracer element of ware down but the high rates of soil makes difficult the measurement of this element, when proceeding from of the ware down. The reason iron/scandium might be useful in identification of iron of mechanical ware down origin, serving as label of soil origin. Iron and thorium are good tracers of soil in sugar cane loads, being usable for the determination of the impurities levels once known their concentration in the sugar cane original soils

  19. Saccharification of recalcitrant biomass and integration options for lignocellulosic sugars from Catchlight Energy's sugar process (CLE Sugar).

    Gao, Johnway; Anderson, Dwight; Levie, Benjamin

    2013-01-28

    Woody biomass is one of the most abundant biomass feedstocks, besides agriculture residuals in the United States. The sustainable harvest residuals and thinnings alone are estimated at about 75 million tons/year. These forest residuals and thinnings could produce the equivalent of 5 billion gallons of lignocellulosic ethanol annually. Softwood biomass is the most recalcitrant biomass in pretreatment before an enzymatic hydrolysis. To utilize the most recalcitrant lignocellulosic materials, an efficient, industrially scalable and cost effective pretreatment method is needed. Obtaining a high yield of sugar from recalcitrant biomass generally requires a high severity of pretreatment with aggressive chemistry, followed by extensive conditioning, and large doses of enzymes. Catchlight Energy's Sugar process, CLE Sugar, uses a low intensity, high throughput variation of bisulfite pulping to pretreat recalcitrant biomass, such as softwood forest residuals. By leveraging well-proven bisulfite technology and the rapid progress of enzyme suppliers, CLE Sugar can achieve a high yield of total biomass carbohydrate conversion to monomeric lignocellulosic sugars. For example, 85.8% of biomass carbohydrates are saccharified for un-debarked Loblolly pine chips (softwood), and 94.0% for debarked maple chips (hardwood). Furan compound formation was 1.29% of biomass feedstock for Loblolly pine and 1.10% for maple. At 17% solids hydrolysis of pretreated softwood, an enzyme dose of 0.075 g Sigma enzyme mixture/g dry pretreated (unwashed) biomass was needed to achieve 8.1% total sugar titer in the hydrolysate and an overall prehydrolysate liquor plus enzymatic hydrolysis conversion yield of 76.6%. At a much lower enzyme dosage of 0.044 g CTec2 enzyme product/g dry (unwashed) pretreated softwood, hydrolysis at 17% solids achieved 9.2% total sugar titer in the hydrolysate with an overall sugar yield of 85.0% in the combined prehydrolysate liquor and enzymatic hydrolysate. CLE Sugar has

    Full Text Available Biogas is one alternative to replace the irreplaceable energy source that has begun to diminish its existence. The raw materials for biogas manufacture are renewable biomass, usually using plantation waste, agriculture, and livestock. Using biogas can also reduce environmental pollution. One of the agricultural waste that has great potential to become the raw material of biogas is teak sawdust. Wood processing industry in Indonesia quite a lot, but wood has a high lignosesluosa content, so it needs the right method to process it. With the delignification of lignin levels on teak sawdust will decrease. Wood sawdust is soaked using NaOH for 1, 2, 3, and 4 days with 4% w / v concentration. The lowest lignin and hemicellulose content was 25.79% and 87.9% in pretreatment for 4 days, while the highest cellulose level was 57, 34%. The accumulated volume of biogas at 1 day pretreatment, ie 709 ml / g TS. Gcms shows the enlarged peak area of methanamine, N-methyl from before pretreatment. The fastest biogas formation (λ in 4 days pretreatment, 1.60403 days and the largest constant A and U variables at 1 day were 914.5903 ml / g TS and 34.59765 ml / g TS.

    During the handling and/or processing of powdered materials in the CERAMICS INDUSTRY, one of the most important risks regarding the environmental and occupational health is the potential generation of dust. In this regard, a parameter of great interest is the dustiness of the processed materials; this parameter quantifies the tendency of the powdered materials to generate dust when handled. In this study, to determine the dustiness of a ceramic raw material composition (mixture of the body raw materials), the continuous drop method has been used. This test apparatus was selected because it is considered to better simulate how ceramic materials are handled in the CERAMICS INDUSTRY. The obtained results show that the dustiness of the same ceramic composition exhibits significant changes during the manufacturing process, depending on the presentation form. In this regard, the dry milling sample presents the highest dustiness, which can be significantly reduced (>75%) applying the the moisturization and agglomeration. The obtained results also shown that the best presentation form, regarding the minimization of the dust generation, is achieved in the spray-drying process, where the dustiness is reduced by 95%.

    Samples of portland cement manufactured in the North West frontier Province (NWFP) of Pakistan and its different raw materials have been investigated applying gamma-spectrometric techniques for natural gamma-emitting radionuclides. A high purity germanium detector (HPGE) was used for data acquisition. Average values of the total specific activity (in Bq.kg/sup -1/ ) due to all the three radionuclides (/sub 40/K, /sup 226/Ra and /sup 232/Th) were found to be 327.7+ - 168.2 for portland cement; 104.4 + - 21.1 for limestone; 193.2+ - 50.4 for gypsum; 890.4 + - 86.5 for state and 545.6+ - 56.6 for latrite. The average specific activities due to /sup 40/K in Portland cement and all the raw materials were found to be higher as compared to /sub 226/Ra and /sup 232/Th in the respective materials. It is concluded that such materials do not pose any health problem and are not a major source of radiation hazards. However, The data can be utilized in determining radioactivity associated with other building materials. (author)

    In the context of cellulosic ethanol production, special attention must be given to the raw material, as it affects final product yield. As observed for sugarcane, bagasse variations may derive from several elements, for instance edaphoclimatic factors, seasonality, maturation stage and harvesting techniques. Therefore, in the present work, to investigate the impact of raw material characteristics on process performance, sugarcane bagasse from four harvests from October/2010 to October/2011 was pretreated by steam explosion and had its soluble and insoluble solids contents measured, following enzymatic hydrolysis to assess glucan conversion. As confirmed by ANOVA, glucose concentration was related to the solids content in the reactor, whereas glucan conversion was related to the enzymatic load. Variations in raw material composition were indeed observed to significantly interfere in the final sugar recovery, probably due to the increase in the impurities observed as a result of the type of harvest performed in 2011.

    Volatile components of raw, dry roasted and oil roasted almonds were isolated by solvent extraction/solvent-assisted flavor evaporation and predominant aroma compounds identified by gas chromatography-olfactometry (GCO) and aroma extract dilutions analysis (AEDA). Selected odorants were quantitated by GC-mass spectrometry and odor-activity values (OAVs) determined. Results of AEDA indicated that 1-octen-3-one and acetic acid were important aroma compounds in raw almonds. Those predominant in dry roasted almonds were methional, 2- and 3-methylbutanal, 2-acetyl-1-pyrroline and 2,3-pentanedione; whereas, in oil roasted almonds 4-hydroxy-2,5-dimethyl-3(2H)-furanone, 2,3-pentanedione, methional and 2-acetyl-1-pyrroline were the predominant aroma compounds. Overall, oil roasted almonds contained a greater number and higher abundance of aroma compounds than either raw or dry roasted almonds. The results of this study demonstrate the importance of lipid-derived volatile compounds in raw almond aroma. Meanwhile, in dry and oil roasted almonds, the predominant aroma compounds were derived via the Maillard reaction, lipid degradation/oxidation and sugar degradation. Copyright © 2016 Elsevier Ltd.

    Biogenic amine accumulation was studied in spontaneously fermented sausages (Fuet) manufactured from unfrozen-fresh meat (U-sausages) and frozen-thawed meat (F-sausages). The aim was to investigate whether the frozen storage of raw materials affects the microbial composition and its aminogenic activity during sausage fermentation. Tyramine was the major amine in all sausages. Although the final levels were similar, tyramine accumulated more rapidly in F-sausages, which contained putrescine as the second amine. By contrast, U-sausages accumulated much more cadaverine than putrescine. F-sausages showed a slightly lower pH and free amino acid content as well as higher counts of technological flora (lactic acid and gram positive catalase positive bacteria) and lower counts of enterobacteria. Therefore, to freeze the meat raw materials for few days before sausage manufacture could be a useful practice, especially for the artisan fermented sausages (without starter), because it helps to reduce enterobacteria development and cadaverine production.

    common interoperable EU Geological Knowledge Base. Such a Knowledge Base will support exploration for indigenous mineral resources and strengthen policy and decision making. In 2010, the European Commission identified 14 non energy non-agricultural raw materials as being critical. Criticality is based on both the scarcity of supply and the importance to European industry. This list was updated in 2014 to include 7 new commodities with one being dropped from the original list. The list now comprises: antimony, beryllium, borates, chromium, cobalt, coking coal, fluorspar, gallium, germanium, graphite, indium, magnesite, magnesium, niobium, phosphate rock, platinum group metals, light and heavy rare earth elements (separately), silicon metal and tungsten. ProMine was a European Union (EU) co-funded project, which had as its main objective the stimulation of the extractive industry to deliver new products to manufacturing industry. A major deliverable of the project was the ProMine Mineral Deposit (MD) database that contains information related to almost 13,000 mineral deposits in Europe. In order to extract data to be displayed on the CRM map of Europe, the ProMine MD database was queried for all commodities on the EC CRM list which were in the medium to super-large deposit size. Following this, the dataset was circulated to MREG in order to verify, validate and update the list.

    No organism lives in a constant environment. Based on classical studies in molecular biology, many have viewed microbes as following strict rules for shifting their metabolic activities when prevailing conditions change. For example, students learn that the bacterium Escherichia coli makes proteins for digesting lactose only when lactose is available and glucose, a better sugar, is not. However, recent studies, including three PLOS Biology papers examining sugar utilization in the budding yeast Saccharomyces cerevisiae, show that considerable heterogeneity in response to complex environments exists within and between populations. These results join similar recent results in other organisms that suggest that microbial populations anticipate predictable environmental changes and hedge their bets against unpredictable ones. The classical view therefore represents but one special case in a range of evolutionary adaptations to environmental changes that all organisms face. PMID:25688600

    Raw accelerometry is increasingly being used in physical activity research, but diversity in sensor design, attachment and signal processing challenges the comparability of research results. Therefore, efforts are needed to harmonize the methodology. In this article we reflect on how increased methodological harmonization may be achieved. The authors of this work convened for a two-day workshop (March 2014) themed on methodological harmonization of raw accelerometry. The discussions at the workshop were used as a basis for this review. Key stakeholders were identified as manufacturers, method developers, method users (application), publishers, and funders. To facilitate methodological harmonization in raw accelerometry the following action points were proposed: i) Manufacturers are encouraged to provide a detailed specification of their sensors, ii) Each fundamental step of algorithms for processing raw accelerometer data should be documented, and ideally also motivated, to facilitate interpretation and discussion, iii) Algorithm developers and method users should be open about uncertainties in the description of data and the uncertainty of the inference itself, iv) All new algorithms which are pitched as "ready for implementation" should be shared with the community to facilitate replication and ongoing evaluation by independent groups, and v) A dynamic interaction between method stakeholders should be encouraged to facilitate a well-informed harmonization process. The workshop led to the identification of a number of opportunities for harmonizing methodological practice. The discussion as well as the practical checklists proposed in this review should provide guidance for stakeholders on how to contribute to increased harmonization.

    Sugar intake has been associated with an increased prevalence of obesity, other noncommunicable diseases, and dental caries. The WHO recommends that free sugars should be ENSANUT (National Health and Nutrition Survey) 2012], which represents 3 geographic regions and urban and rural areas. Dietary information was obtained by administering a 24-h recall questionnaire to 10,096 participants. Total sugar intake was estimated by using the National Institute of Public Health (INSP) food-composition table and an established method to estimate added sugars. The mean intakes of total, intrinsic, and added sugars were 365, 127, and 238 kcal/d, respectively. Added sugars contributed 13% of TEI. Sugar-sweetened beverages (SSBs) were the main source of sugars, contributing 69% of added sugars. Food products high in saturated fat and/or added sugar (HSFAS) were the second main sources of added sugars, contributing 25% of added sugars. The average intake of added sugars in the Mexican diet is higher than WHO recommendations, which may partly explain the high prevalence of obesity and diabetes in Mexico. Because SSBs and HSFAS contribute >94% of total added sugars, strategies to reduce their intake should be strengthened. This includes stronger food labels to warn the consumer about the content of added sugars in foods and beverages. © 2016 American Society for Nutrition.

    In Ukraine 13 VVER-1000 and 2 VVER-440 reactor units generate about 50 % of the country's energy production. By contrast, when looking at the large volume of radioactive waste of all categories, which is produced by these nuclear power plants (NPP), the radioactive waste (RAW) management - onsite of NPP, towards interim storage as well as towards final disposal - is still not adequately developed. Currently all operational waste of Ukrainian NPP is incompletely treated/conditioned and stored onsite, though insufficient storage capacity is available at the NPP. As no effective Ukraine-wide strategy is yet established to manage RAW beyond NPP a serious situation could arise, which even leads to constrained temporary shut-down of reactor units, threatening the energy supply of whole the country. In addition large quantities of RAW, partly badly sorted, derive from decommissioning of the shut-down Chernobyl NPP. Also other sources of RAW contribute to the whole volume, which has to be managed in Ukraine, as research reactors, reprocessing of spent nuclear fuel and other nuclear facilities and applications. Nevertheless, operational and shut-down NPP in Ukraine are by far the largest producers. To support Ukraine in managing their radioactive waste NUKEM Technologies GmbH was appointed to provide technical support for the improvement of the current situation in cooperation with responsible Ukrainian experts towards a targeted, comprehensive and effective RAW management.

    To contribute evidence and make recommendations to assist in achieving free sugars reduction, with due consideration to the broader picture of weight management and dietary quality. An expert workshop in July 2016 addressed options outlined in the Public Health England report 'Sugar reduction: The evidence for action' that related directly to the food industry. Panel members contributed expertise in food technology, public heath nutrition, marketing, communications, psychology and behaviour. Recommendations were directed towards reformulation, reduced portion sizes, labelling and consumer education. These were evaluated based on their feasibility, likely consumer acceptability, efficacy and cost. The panel agreed that the 5% target for energy from free sugars is unlikely to be achievable by the UK population in the near future, but a gradual reduction from average current level of intake is feasible. Progress requires collaborations between government, food industry, non-government organisations, health professionals, educators and consumers. Reformulation should start with the main contributors of free sugars in the diet, prioritising those products high in free sugars and relatively low in micronutrients. There is most potential for replacing free sugars in beverages using high-potency sweeteners and possibly via gradual reduction in sweetness levels. However, reformulation alone, with its inherent practical difficulties, will not achieve the desired reduction in free sugars. Food manufacturers and the out-of-home sector can help consumers by providing smaller portions. Labelling of free sugars would extend choice and encourage reformulation; however, government needs to assist industry by addressing current analytical and regulatory problems. There are also opportunities for multi-agency collaboration to develop tools/communications based on the Eatwell Guide, to help consumers understand the principles of a varied, healthy, balanced diet.

  16. Scientists Discover Sugar in Space

    2000-06-01

    The prospects for life in the Universe just got sweeter, with the first discovery of a simple sugar molecule in space. The discovery of the sugar molecule glycolaldehyde in a giant cloud of gas and dust near the center of our own Milky Way Galaxy was made by scientists using the National Science Foundation's 12 Meter Telescope, a radio telescope on Kitt Peak, Arizona. "The discovery of this sugar molecule in a cloud from which new stars are forming means it is increasingly likely that the chemical precursors to life are formed in such clouds long before planets develop around the stars," said Jan M. Hollis of the NASA Goddard Space Flight Center in Greenbelt, MD. Hollis worked with Frank J. Lovas of the University of Illinois and Philip R. Jewell of the National Radio Astronomy Observatory (NRAO) in Green Bank, WV, on the observations, made in May. The scientists have submitted their results to the Astrophysical Journal Letters. "This discovery may be an important key to understanding the formation of life on the early Earth," said Jewell. Conditions in interstellar clouds may, in some cases, mimic the conditions on the early Earth, so studying the chemistry of interstellar clouds may help scientists understand how bio-molecules formed early in our planet's history. In addition, some scientists have suggested that Earth could have been "seeded" with complex molecules by passing comets, made of material from the interstellar cloud that condensed to form the Solar System. Glycolaldehyde, an 8-atom molecule composed of carbon, oxygen and hydrogen, can combine with other molecules to form the more-complex sugars Ribose and Glucose. Ribose is a building block of nucleic acids such as RNA and DNA, which carry the genetic code of living organisms. Glucose is the sugar found in fruits. Glycolaldehyde contains exactly the same atoms, though in a different molecular structure, as methyl formate and acetic acid, both of which were detected previously in interstellar clouds

    Full Text Available The first part of this review article considers general data about ethanol as an industrial product, its qualities and uses. It is emphasized that, if produced from biomass as a renewable raw material, its perspectives as a chemical raw material and energent are brilliant. Starchy grains, such as corn, must be used as the main raw materials for ethanol production. The production of bioethanol by the enzyme-catalyzed conversion of starch followed by (yeast fermentation, distillation is the process of choice. If used as a motor fuel, anhydrous ethanol can be directly blended with gasoline or converted into an oxygenator such as ETBE. Finally, bioethanol production in Yugoslavia and the possibilities for its further development are discussed.

    When a raw sweet potato root is analysed, only sucrose, glucose and fructose are present but during cooking, starch is hydrolysed into maltose giving the sweet flavour to cooked roots. This study aimed at developing an HPTLC protocol for the rapid quantitative determination of maltose and total sugars in four commercial varieties and to compare them to 243 hybrids grouped by flesh colour (white, orange, purple). In commercial varieties, mean maltose content varied from 10.26 to 15.60% and total sugars from 17.83 to 27.77% on fresh weight basis. Hybrids showed significant variation in maltose content within each group, with means ranging from 7.65% for white-fleshed, to 8.53% in orange- and 11.98% in purple-fleshed. Total mean sugars content was 20.24, 22.11 and 26.84% respectively for white, orange and purple flesh hybrids. No significant correlations were detected between individual sugars but maltose and total sugars content were highly correlated. Compared to the best commercial variety ( Baby ), 25 hybrids (10.3%) presented a higher maltose content and 40 (16.5%) showed a higher total sugars content. HPTLC was observed as an attractive, cost efficient, high-throughput technique for quantitating maltose and total sugars in sweet potatoes. Perspectives for improving sweet potato quality for consumers' requirements are also discussed.

    The economic growth of an industrialized nation such as the United States requires raw materials for construction (buildings, bridges, highways, and so forth), defense, and processing and manufacture of goods and services. Since the beginning of the 20th century, the types and quantities of raw materials used have increased and changed significantly. This fact sheet quantifies the amounts of raw materials (other than food and fuel) that have been used in the U.S. economy annually for a period of 115 years, from 1900 through 2014. It provides a broad overview of the quantity (weight) of nonfood and nonfuel materials used in the economy and illustrates the use and significance of raw nonfuel minerals in particular as building blocks of society.These data have been compiled to help the public and policymakers understand the changing annual flow of raw materials put into use in the United States. Such information can be helpful in assessing the potential effects of materials use on the environment, assessing materials’ intensity of use, and examining the role that these materials play in the economy. The data presented indicate the substitution and shift in materials usage from renewable to nonrenewable materials during the 20th century. The disaggregated quantities by commodity (not shown in this fact sheet) may be tested against supply adequacy and end of life issues.

    Ethanol production from sugarcane bagasse requires a pretreatment step to disrupt the cellulose-hemicellulose-lignin complex and to increase biomass digestibility, thus allowing the obtaining of high yields of fermentable sugars for the subsequent fermentation. Hydrothermal and lime pretreatments have emerged as effective methods in preparing the lignocellulosic biomass for bioconversion. These pretreatments are advantageous because they can be performed under mild temperature and pressure conditions, resulting in less sugar degradation compared with other pretreatments, and also are cost-effective and environmentally sustainable. In this study, we evaluated the effect of these pretreatments on the efficiency of enzymatic hydrolysis of raw sugarcane bagasse obtained directly from mill without prior screening. In addition, we evaluated the structure and composition modifications of this bagasse after lime and hydrothermal pretreatments. The highest cellulose hydrolysis rate (70 % digestion) was obtained for raw sugarcane bagasse pretreated with lime [0.1 g Ca(OH)2/g raw] for 60 min at 120 °C compared with hydrothermally pretreated bagasse (21 % digestion) under the same time and temperature conditions. Chemical composition analyses showed that the lime pretreatment of bagasse promoted high solubilization of lignin (30 %) and hemicellulose (5 %) accompanied by a cellulose accumulation (11 %). Analysis of pretreated bagasse structure revealed that lime pretreatment caused considerable damage to the bagasse fibers, including rupture of the cell wall, exposing the cellulose-rich areas to enzymatic action. We showed that lime pretreatment is effective in improving enzymatic digestibility of raw sugarcane bagasse, even at low lime loading and over a short pretreatment period. It was also demonstrated that this pretreatment caused alterations in the structure and composition of raw bagasse, which had a pronounced effect on the enzymes accessibility to the

    Non-glucose sugars derived from lignocellulose cover approximately 40% of the total carbohydrates of lignocellulose biomass. The conversion of the non-glucose sugars to the target products is an important task of lignocellulose biorefining research. Here we report a fast and complete conversion of the total non-glucose sugars from corn stover into the corresponding sugar acids by whole cell catalysis and aerobic fermentation of Gluconobacter oxydans. The conversions include xylose to xylonate, arabinose to arabonate, mannose to mannonate, and galactose to galactonate, as well as with glucose into gluconate. These cellulosic non-glucose sugar acids showed the excellent cement retard setting property. The mixed cellulosic sugar acids could be used as cement retard additives without separation. The conversion of the non-glucose sugars not only makes full use of lignocellulose derived sugars, but also effectively reduces the wastewater treatment burden by removal of residual sugars.

    In commercial ethanol production procedures often use sugar cane molasses as a raw material due to- their abundance and low costs. The most employed microorganisms used for fermentation is Saccharomyces cerevisiae yeasts due to their ability to hydrolyze sucrose from sugar cane molasses into glucose and fructose; two easily assimilable hexoses. The aim of this study was to evaluate the effect of gamma irradiation on the activity of S. cerevisiae in the ethanol production yeast cells exposed to different doses of gamma rays (0.05, 0.1, 0.2, 0.4, 0.6, 0.8 and 1.0 KGy. The sugar cane substrate was optimized after maintaining deferent levels of sugar concentrations (12-21%), medium ph (4.0-5.5), incubation temperature (25-40 degree C) and rate of fermentation (24-168 h). The data showed that the rate of ethanol production reached its maximum by using the irradiated S. cerevisiae cells at 0.1 kGy dose at fermentation conditions as 15% sugar concentration, ph 4.5, incubation temperature 30 degree C, fermentation time 96 h at a fermentation medium volume 250 ml found in 500 ml Erlenmeyer flasks.

    2013-09-01

    To investigate what level of sugar reduction is accepted in flavored yogurt, we conducted a hedonic test focusing on the degree of liking of the products and on optimal sweetness and aroma levels. For both flavorings (strawberry and coffee), consumers preferred yogurt containing 10% added sugar. However, yogurt containing 7% added sugar was also acceptable. On the just-about-right scale, yogurt containing 10% sugar was more often described as too sweet compared with yogurt containing 7% sugar. On the other hand, the sweetness and aroma intensity for yogurt containing 5% sugar was judged as too low. A second test was conducted to determine the effect of flavoring concentration on the acceptance of yogurt containing 7% sugar. Yogurts containing the highest concentrations of flavoring (11% strawberry, 0.75% coffee) were less appreciated. Additionally, the largest percentage of consumers perceived these yogurts as "not sweet enough." These results indicate that consumers would accept flavored yogurts with 7% added sugar instead of 10%, but 5% sugar would be too low. Additionally, an increase in flavor concentration is undesirable for yogurt containing 7% added sugar. Copyright © 2013 American Dairy Science Association. Published by Elsevier Inc.

    As obesity rates continue to climb, the notion that overconsumption reflects an underlying 'food addiction' (FA) has become increasingly influential. An increasingly popular theory is that sugar acts as an addictive agent, eliciting neurobiological changes similar to those seen in drug addiction. In this paper, we review the evidence in support of sugar addiction. We reviewed the literature on food and sugar addiction and considered the evidence suggesting the addictiveness of highly processed foods, particularly those with high sugar content. We then examined the addictive potential of sugar by contrasting evidence from the animal and human neuroscience literature on drug and sugar addiction. We find little evidence to support sugar addiction in humans, and findings from the animal literature suggest that addiction-like behaviours, such as bingeing, occur only in the context of intermittent access to sugar. These behaviours likely arise from intermittent access to sweet tasting or highly palatable foods, not the neurochemical effects of sugar. Given the lack of evidence supporting it, we argue against a premature incorporation of sugar addiction into the scientific literature and public policy recommendations.

    The aim of this study was to investigate the effect of deer bone oil extract (DBOE) on lipopolysaccharide (LPS)-induced inflammatory responses in RAW264.7 cells. DBOE was fractionated by liquid-liquid extraction to obtain two fractions: methanol fraction (DBO-M) and hexane fraction (DBO-H). TLC showed that DBO-M had relatively more hydrophilic lipid complexes, including unsaturated fatty acids, than DBOE and DBO-H. The relative compositions of tetradecenoyl carnitine, α-linoleic acid, and palmitoleic acid increased in the DBO-M fraction by 61, 38, and 32%, respectively, compared with DBOE. The concentration of sugar moieties was 3-fold higher in the DBO-M fraction than DBOE and DBO-H. DBO-M significantly decreased LPS-induced nitric oxide (NO) production in RAW264.7 cells in a dose-dependent manner. This DBO-M-mediated decrease in NO production was due to downregulation of mRNA and protein levels of inducible nitric oxide synthase (iNOS). In addition, mRNA expression of pro-inflammatory mediators, such as cyclooxygenase (COX-2), interleukin (IL)-1β, and IL-12β, was suppressed by DBO-M. Our data showed that DBO-M, which has relatively higher sugar content than DBOE and DBO-H, could play an important role in suppressing inflammatory responses by controlling pro-inflammatory cytokines and mediators.

    Hot-melt extruded sugar-starch pellets are an alternative for commercial sugar spheres, but their coating properties remain to be studied. Both the European Pharmcopoeia 8.6 and the United States Pharmacopoeia 40 specify the composition of sugar-starch pellets without giving requirements for the manufacturing process. Due to various fabrication techniques, the physicochemical properties of pellets may differ. Therefore, the adhesion energies of three coating dispersions (sustained, enteric and immediate release) on different types of pellets were investigated. In this context, the surface energies of various kinds of corn starch (normal, waxy, high-amylose) and sucrose pellets were analyzed using the sessile drop method, whereas the surface tensions of the coating dispersions were examined using the pendant drop method. The adhesion forces were calculated from the results of these studies. Furthermore, sugar spheres were characterized in terms of particle size distribution, porosity and specific surface area. An increase of the pellets' sucrose content leads to a more porous surface structure, which gives them an enhanced wetting behavior with coating dispersions. The adhesion energies of extruded sugar-starch pellets are similar to those of commercial sugar spheres, which comply with pharmacopeial requirements. Both types of pellets are equally suited for coating.

  15. Reducing Added Sugars in the Food Supply Through a Cap-and-Trade Approach

    Objectives. We estimated the effect of a simulated cap-and-trade policy to reduce added sugar in the food supply. Methods. Using nationally representative data on added-sugar content and consumption, we constructed a mathematical model of a cap-and-trade policy and compared its health implications to those of proposals to tax sugar sweetened beverages or added sugars. Results. Capping added-sugar emissions into the food supply by food manufacturers at a rate of 1% per year would be expected to reduce the prevalence of obesity by 1.7 percentage points (95% confidence interval [CI] = 0.9, 2.4; a 4.6% decline) and the incidence of type 2 diabetes by 21.7 cases per 100 000 people (95% CI = 12.9, 30.6; a 4.2% decline) over 20 years, averting approximately $9.7 billion in health care spending. Racial and ethnic minorities would be expected to experience the largest declines. By comparison, equivalent price penalties through excise taxes would be expected to generate smaller health benefits. Conclusions. A cap-and-trade policy to reduce added-sugar intake may reduce obesity and type 2 diabetes to a greater extent than currently-proposed excise taxes. PMID:25365146

    Timson David J

    2003-11-01

    Full Text Available Abstract Background Galactokinase catalyses the first committed step of galactose catabolism in which the sugar is phosphorylated at the expense of MgATP. Recent structural studies suggest that the enzyme makes several contacts with galactose – five side chain and two main chain hydrogen bonds. Furthermore, it has been suggested that inhibition of galactokinase may help sufferers of the genetic disease classical galactosemia which is caused by defects in another enzyme of the pathway galactose-1-phosphate uridyl transferase. Galactokinases from different sources have a range of substrate specificities and a diversity of kinetic mechanisms. Therefore only studies on the human enzyme are likely to be of value in the design of therapeutically useful inhibitors. Results Using recombinant human galactokinase expressed in and purified from E. coli we have investigated the sugar specificity of the enzyme and the kinetic consequences of mutating residues in the sugar-binding site in order to improve our understanding of substrate recognition by this enzyme. D-galactose and 2-deoxy-D-galactose are substrates for the enzyme, but N-acetyl-D-galactosamine, L-arabinose, D-fucose and D-glucose are all not phosphorylated. Mutation of glutamate-43 (which forms a hydrogen bond to the hydroxyl group attached to carbon 6 of galactose to alanine results in only minor changes in the kinetic parameters of the enzyme. Mutation of this residue to glycine causes a ten-fold drop in the turnover number. In contrast, mutation of histidine 44 to either alanine or isoleucine results in insoluble protein following expression in E. coli. Alteration of the residue that makes hydrogen bonds to the hydroxyl attached to carbons 3 and 4 (aspartate 46 results in an enzyme that although soluble is essentially inactive. Conclusions The enzyme is tolerant to small changes at position 2 of the sugar ring, but not at positions 4 and 6. The results from site directed mutagenesis could

    Suspended particles released in glass manufacture were subjected to multielement analysis by means of instrumental neutron activation method and energy dispersive X-ray fluorescence spectrometry. Suspended particles emitted from glass manufacture generally consist of both particles emitted from glass fusion and those produced through fuel combustion (mainly oil combustion). Elemental compositions of suspended particles emitted from glass fusion were found to be strongly dependent on the kind and recipe of raw materials and additives. Of the various metallic elements involved in suspended particles emitted from glass fusion, the elements, As, Se, Cd, Sb, Pb and so on are regarded to produce the most serious air pollution. The amount of emission of these elements to the environment is, howerer, quite varied from manufacturer to manufacturer. The replacement of electric furnace by oil combustion in opal glass manufacture remarkably reduced the emission of metallic elements to the environment.

    Sugar is one of the basic needs of people and food and drink industry. As technology advances and the demand for efficient usage of sugar rises, crystal sugar is seen as less advantageous than liquid sugar. If sugar is always dissolved in water before use, then it will be more efficient and practical for consumers to use sugar in liquid form than in crystal form. Other than that, liquid sugar is also attractive to consumers because it is economical, hygienic, instantly soluble in hot and cold water, fresher and longer-lasting, able to thicken and enrich the texture of foods and drinks, and functions as sweetener, syrup, and flavor enhancer. Liquid sugar is also more beneficial for sugar producers because of simpler production process, cheaper production cost, and similar yield with no extra cost. In sugar production, separation process is found in most of its stages and therefore the use of membrane technology for separating solute and water content has a good potential. In this research, water content reduction of sugar solution was done in order to increase the sugar concentration of the solution. The parameters of this research were 4%, 5%, and 6% starting concentration of sugar solution; 20, 40, and 60 minutes of process time; and 85 and 60 PSI ΔP. The best result was acquired on 4% starting concentration, 60 PSI ΔP, and 60 minutes process time.

    Full Text Available Ice cream is a tasty and nutritious source of protein and calcium, but it is deficient in some minerals, as iron, but it is found in sugar cane juice, which is a source of minerals such as iron, phosphorus, calcium, sodium among others. The objective of the present study are: to develop sugar cane juice ice cream, in order to increase the mineral content replacing refined sugar and water during the manufacturing process by sugar cane juice; to analyze its physical-chemical composition; to check your sensory acceptance with children. Three formulations were prepared from sugar cane juice ice cream: sugar cane juice ice cream (SC, sugar cane juice ice cream with molasses (SCM and sugar cane juice ice cream with brown sugar (SCR. Sensory evaluation was conducted with 120 children (62 boys and 58 girls from 8 to 10 years old, students from 3rd to 5th years of primary school. Sensory tests were ordering-preference, intention to use and acceptance with facial hedonic scale of 7 points. The results of physico-chemical and acceptance testing were statistically analyzed by analysis of variance (ANOVA, the scores compared by Tukey test (p ? 0.05 and the result of the sensory test ordering-preference were assessed using the Friedman. The ice cream it presents has a reduced fat content because it was formulated with palm trans-fat free. The use of sugar cane juice in the formulation of the ice cream increased the amount of minerals when compared to ordinary ice cream. Therefore, sugar cane juice ice cream demonstrated to be more healthy and nutritious compared with traditional ice cream, besides being source of calcium, iron and phosphorus; serving the needs of the recommended daily intake (IDR for children from 7 to 10 years old. About the sensory evaluation, all formulations of sugar cane juice ice cream obtained great sensory acceptance among children in all sensory attributes evaluated, showing excellent percentages of acceptance and intention to use by

  5. Sugar-free medicines are counterproductive.

    Sundar, S

    2012-09-01

    Sugar in food and drinks is responsible for the poor dental health of many children and adults. On the other hand, there is no evidence that the small amount of sugar in medicines has been responsible for any dental problems. A recent British Heart Foundation survey found that nearly one in three UK children are eating sweets, chocolate and crisps three or more times a day. Hence it is futile administering sugar-free medicine to a child consuming lot of sweets. Moreover, sugar in medicines makes them palatable and bitter medicines inevitably affect compliance with the prescribed treatment. Poor compliance leads to inadequate treatment of illness and consequently increases the risk of complications from illness. Hence sugar-free medicines promoted as a public health policy could have actually caused more harm than any meaningful net benefit. There is an urgent need for a healthy debate and a fresh look at the policy of promoting sugar-free medicines.

    1998-12-01

    Two different concentrations (approx. 6 and 12%) and two presentations (raw and cooked) of dehydrated nopal were fed to laboratory rats and growth and serum total cholesterol, lipoprotein profile and glucose determined. Samples of raw and cooked nopal were chemically characterized for moisture, protein, ash, crude fiber, ether extract, total dietary fiber, reducing sugars, amino acids, minerals and gross energy. Cooking slightly affected some of the nutrients analyzed. After one month feeding, blood was withdrawn via intracardiac puncture and serum glucose, total cholesterol, HDL, LDL, and VLDL were determined. Rats fed 12% nopal had lower weight gains (P nopal or the control diet. Consumption of nopal did not affect (P > 0.05) glucose, total cholesterol and HDL cholesterol levels. However, rats fed raw nopal at the 12% concentration level had a 34% reduction in LDL cholesterol levels; thus, it was concluded that raw nopal had a potentially beneficial effect for hypercholesterolemic individuals.

    Effective analysis of protein samples by mass spectrometry (MS) requires careful selection and optimization of a range of experimental parameters. As the output from the primary detection device, the "raw" MS data file can be used to gauge the success of a given sample analysis. However, the closed-source nature of the standard raw MS file can complicate effective parsing of the data contained within. To ease and increase the range of analyses possible, the RawQuant tool was developed to enable parsing of raw MS files derived from Thermo Orbitrap instruments to yield meta and scan data in an openly readable text format. RawQuant can be commanded to export user-friendly files containing MS 1 , MS 2 , and MS 3 metadata as well as matrices of quantification values based on isobaric tagging approaches. In this study, the utility of RawQuant is demonstrated in several scenarios: (1) reanalysis of shotgun proteomics data for the identification of the human proteome, (2) reanalysis of experiments utilizing isobaric tagging for whole-proteome quantification, and (3) analysis of a novel bacterial proteome and synthetic peptide mixture for assessing quantification accuracy when using isobaric tags. Together, these analyses successfully demonstrate RawQuant for the efficient parsing and quantification of data from raw Thermo Orbitrap MS files acquired in a range of common proteomics experiments. In addition, the individual analyses using RawQuant highlights parametric considerations in the different experimental sets and suggests targetable areas to improve depth of coverage in identification-focused studies and quantification accuracy when using isobaric tags.

    2015-12-01

    Hauling is a critical part of the commercial milk supply chain, yet very few studies have aimed to understand its effect on raw milk quality. This study focused on the effect of extended-duration tanker use during hauling on raw milk quality at a commercial facility. Standard tanker use [cleaned-in-place (CIP) once per 24h] served as a control and an incremental between-load water rinse with sanitizer treatment (RS) was evaluated to mitigate any effect from extended duration hauling. During this study, 1 commercial truck with 2 trailers was monitored for 10d. The truck collected milk at a large dairy farm, transported the milk to a manufacturing facility, and then returned to the same farm for a second load. Each round-trip journey took between 10 and 12h, allowing for 2 loads per 24-h use period. Following the second delivery, the truck was cleaned by CIP treatment starting a new treatment day. Producer samples were collected from the raw milk bulk tank on the farm before loading milk into the tanker. The same milk was sampled directly out of the tanker truck before unloading at the manufacturer. Effect on individual bacteria count, thermophilic spore count, and preliminary incubation count was quantified through common industry tests. Surface sponge swabs were also used to monitor tanker sanitation and the efficacy of cleaning treatments. Results did not identify a negative effect on raw milk quality due to extended duration hauling. Whereas the addition of RS did not provide any measurable quality benefits for the microbial milk quality, swab results demonstrated that the RS treatment was able to reduce surface bacteria in the tanker, although not to the same level as the full CIP treatment. Based on this study, current CIP practices for long distance milk hauling appear to be effective in mitigating any measurable effect on raw milk quality.

    The consumption of sugars, particularly sugar-sweetened beverages (SSBs; beverages or drinks that contain added caloric sweeteners (ie, sucrose, high-fructose corn syrup, fruit juice concentrates), in European children and adolescents exceeds current recommendations. This is of concern because there is no nutritional requirement for free sugars, and infants have an innate preference for sweet taste, which may be modified and reinforced by pre- and postnatal exposures. Sugar-containing beverages/free sugars increase the risk for overweight/obesity and dental caries, can result in poor nutrient supply and reduced dietary diversity, and may be associated with increased risk of type 2 diabetes mellitus, cardiovascular risk, and other health effects. The term "free sugars," includes all monosaccharides/disaccharides added to foods/beverages by the manufacturer/cook/consumer, plus sugars naturally present in honey/syrups/unsweetened fruit juices and fruit juice concentrates. Sugar naturally present in intact fruits and lactose in amounts naturally present in human milk or infant formula, cow/goat milk, and unsweetened milk products is not free sugar. Intake of free sugars should be reduced and minimised with a desirable goal of advertising, introducing standards for kindergarten and school meals, and fiscal measures, depending on local circumstances.

    A laboratory procedure is described for hydrolyzing cellulose material to sugars by the use of hot sulfuric acid. The procedure has been used routinely for assessing raw materials. Raw materials used were radiata pine (fresh wood and decayed thinnings), pine needles, sawdust from old dumps, newspaper, cardboard, beech wood, and coconut wood. The neutralized sugar-liquors produced, supplemented with fertilizer grade nutrients, were fermented with bakers' yeast and gave near optimal conversion of hexoses to ethanol and of pentoses to protein biomass. From 100 g radiata pine (wood: bark mix 85:15) 25 ml (20 g) of ethanol and 2 g yeast biomass were routinely produced, although fermentation rates were lower than with pure sugars. The results, however, clearly showed that, by a hot dilute sulfure acid hydrolysis followed by a yeast fermentation process, cellulose resources avaliable in New Zealand are suitable for conversion to ethanol. 5 table, 1 figure.

  1. The model for the calculation of the dispersed iron ore resource purchase cost in the world class manufacturing (WCM logistics pillar context

    M. Dudek

    2014-10-01

    Full Text Available In the blast-furnace production, raw materials may account for approx. 50 % of the pig-iron manufacture costs. Therefore, any, even small, saving in the sphere of raw material purchasing will translate into the reduction in the cost of the pig-iron manufacture. The selection of appropriate supply sources and the associated raw material quality influencing the economic viability of the charge blend constitutes a multi-faceted optimization task. The paper presents a modified model for production cost estimation at the moment of making raw material purchasing, which is possible to be used in the logistics pillar of the WCM concept.

    During the manufacturing process in the cement industry, raw materials of different levels of natural radioactivity are utilized. In this study we present the radiological impact of cements as a building material and the different raw materials used in their manufacture. A total of 218 samples of raw materials and their end product cements were collected from the cement industry of Macedonia (The Former Yugoslav Republic) during the period 2005-2007. The specific activities, evaluated by gamma spectrometry analysis, showed the highest mean specific activity in fly ash ( 226 Ra, 107 ± 45 Bq kg -1 ; 232 Th, 109 ± 30 Bq kg -1 ; 40 K, 685 ± 171 Bq kg -1 ), which is used as a raw material. However, the final cement product usually has relatively lower activity compared with the activity of the raw material and the mean specific activity of the final cement products were lower ( 226 Ra, 42 ± 10 Bq kg -1 ; 232 Th, 28 ± 6 Bq kg -1 ; 40 K, 264 ± 50 Bq kg -1 ). The radium equivalent activity and the hazard index were calculated for each sample to assess the radiation hazard. The mean annual effective dose originating from the cements was found to be 111 ± 22 μSv y -1 , which is below the recommended EC limit of 300 μSv y -1 .

This paper is aimed at estimating those impacts on the international trade of manufacturing sector in Indonesia for period 2007 to 2014. To conduct estimation, it uses multiple regression analysis on two models: First, the import of raw-and-auxiliary materials; Second, the export of manufacturing sector. The results show that the exchange rate impacts both work significantly on the import of raw-and-auxiliary materials. The finding implies that, through the import of raw-and-auxiliary materials, manufacturing sector is very susceptible to the shock caused by exchange rate changes. Meanwhile, the export of manufacturing sector is not able to take advantage of the depreciation of the exchange rate due to the lack of competitiveness.DOI: 10.15408/sjie.v6i2.5210

    Sugar cane bagasse is waste from the sugar and ethanol industry and is primarily intended for burning in boilers to generate energy. As waste from the cogeneration of energy, sugar cane bagasse ashes (SCBA) are produced with no honorable destination. This paper studies the use of SCBA to partially replace Portland cement in producing cementitious composites. The ashes were processed by reburning and grinding, and after processing were characterized by a scanning electron microscope, x-ray diffraction, laser granulometry, and x-ray fluorescence spectrometry. After characterization, cement compounds were fashioned, replacing 0, 10, 20 and 30% of the cement with SCBA. The composites were mechanically evaluated by means of compression strength tests, tensile strength tests by bending. The results proved significant, indicating the possible use of SCBA when added to the cement on manufacture. (author)

    Full Text Available Sugar beet leaves now are very widely used for livestock feeding, as an organic fertiliser, and also as a raw material for the production of biogas. Therefore the harvest of the sugar beet tops (including leaves can be considered as current task for the sugar beet growing system. Modern technologies involve harvest of the tops of sugar beet in two stages: flat basic cut and collecting of the entire green mass at higher altitude and the subsequent cutting of the heads of root crops from the residues. Therefore, topical issues of the sensing of the heads of sugar beet roots arranged in rows, are related to the majority of the sugar beet toppers, cleaners of the sugar beet heads, leaves cutters and, digging up working bodies of some designs. The aim of this study is theoretical determination the optimum design and kinematic parameters of a new sensing mechanism of the sugar beet heads located in the soil on the basis of the theory of interaction of flat passive swath board sensing organ with the sugar beet heads during their topping when located in the soil. In the study there are used methods of creation of mathematical models of functioning of the agricultural machines and their working bodies with the using of main provisions of mathematics, theoretical mechanics, programming and numerical calculations on the PC. In this paper, there is presented a theoretical study of the interaction of passive sensing organ with the head of the sugar beet root when there are located residues of the leaves on a root head spherical surface in the form of short elastic rods. Thus, for such an interaction of the sensing organ and the head of sugar beet root head there is taken into account elastic-damping properties of the sugar beet leaves residues. In the study there was first of all developed a new design of the topper for sugar beet heads with the use of a flat swath board sensing organ, there was developed the equivalent scheme of the interaction of the

    Full Text Available Milk production in Thailand has gradually increased since 1961. Occasional oversupply of raw milk has become one of dairy farmers' major problems. Increasing the consumption of milk by making use of its separated nutrients may offer a solution. This study was to assess the composition of raw milk produced in Thailand, which included fat, protein, lactose, solid-not-fat (SNF and total solid (TS. A large dairy cooperatives in Saraburi Province was selected for the study. About 9% of its total members, constituting 108 farms, were randomly chosen. They consisted of small size (less than 20 cows/farm, medium size (21-100 cows/farm and large size (>100 cows/farm. The majority was medium-size. Raw milk from each farm was sampled at the delivery site of the cooperatives in the morning. Milk data of the 108 farms were compiled at 3 different periods between February and July 2003. The raw milk was analyzed by the Fourier Transform Infrared Analysis (FTIR using MilkoScan FT6000. The results showed the average fat content of 3.50±0.47%, protein of 3.13±0.16%, lactose of 4.59±0.12%, SNF of 8.42±0.20%, and TS of 11.92±0.54%. The samples were superior in all of the nutrients as compared to the standard levels set by the Department of Livestock Development, except for TS. This indicates the possibility of a local production of milk nutrients such as lactose and protein as ingredients for the pharmaceutical and health food industries.

    2014-03-01

    Full Text Available This paper deals with raw material problems in the territory of West Central Serbia geologically determined as the Čačak-Kraljevo (or West Morava basin. Our research is presented through the most striking case studies, Lojanik, Vlaška Glava and Lazac.  The Lojanik hill is a silicified forest by origin. It has occasionally been in use from the earliest periods of prehistory until today as a source of black and ochre-coloured flint, opal and silicified wood. A detailed prospection, including the mapping of surface finds using square nets, was conducted during two research campaigns.The Vlaška Glava is an open-air Palaeolithic site at which artefacts made of white, ochre, red, brown and black chert, silicified magnesite, volcanic and metamorphic rocks were found. Our research of primary and secondary geological deposits in the vicinity of the site showed equivalent raw material. We also found an interesting primary deposit of high quality bluish grey flint with outcrop activities (Workshop 1.The Lazac shaft is a contemporary magnesite mine, recently abandoned because of the high percentage of silicon-dioxide. We determined the same raw material in collections found at nearby Neolithic sites. Certain similarities between the wooden support systems of ore exploration in the Middle Ages and modern times were established at the entrance of the shaft.Our research in the territory of the West Morava basin resulted in reconstruction of some links between geological deposits and settlements and also creation of a relevant base for future raw material studies.

    Full Text Available Lignocellulosic biomass is a potential raw material that can be used in the synthesis (manufacture of porous carbon stuffs. The properties of such porous carbon products are affected by the species of the raw material and the manufacturing process, among other things. This paper scrutinizes the related characteristics of lignocellulosic raw materials that indicate potential for the production of porous carbon. Three species were used: pine (Pinus merkusii wood, mangium (Acacia mangium wood, and candlenut (Aleurites moluccana shells, representing softwoods, hardwoods, and non-wood stuffs, respectively. Analyses of their chemical compounds and proximate contents were carried out. Additionally, nano scale scrutiny of the lignocellulosic biomass was also conducted using the nano capable instruments, which consisted of SEM, EDS, XRD, FTIR, and DSC. Results revealed that pine wood had the most potential to produce porous carbon. Morphologically, pine wood afforded the best permeability, whereby at the structure of monoclinic cellulose crystals, there were cellulose-I(alpha structures, which contained less cellulose-I(beta structures. Furthermore, pine wood exhibited greater volatile matter content, as confirmed through the FTIR, which greatly assisted the forming of porosity inside its corresponding carbon.

  11. Microbiological Spoilage of High-Sugar Products

    Science.gov (United States)

    Thompson, Sterling

    The high-sugar products discussed in this chapter are referred to as chocolate, sugar confectionery (non-chocolate), liquid sugars, sugar syrups, and honey. Products grouped in the sugar confectionery category include hard candy, soft/gummy candy, caramel, toffee, licorice, marzipan, creams, jellies, and nougats. A common intrinsic parameter associated with high-sugar products is their low water activity (a w), which is known to inhibit the growth of most spoilage and pathogenic bacteria. However, spoilage can occur as a result of the growth of osmophilic yeasts and xerophilic molds (Von Richter, 1912; Anand & Brown, 1968; Brown, 1976). The a w range for high-sugar products is between 0.20 and 0.80 (Banwart, 1979; Richardson, 1987; Lenovich & Konkel, 1992; ICMSF, 1998; Jay, Loessner, & Golden, 2005). Spoilage of products, such as chocolate-covered cherries, results from the presence of yeasts in the liquid sugar brine or the cherry. Generally, the spoiled product will develop leakers. The chocolate covering the cherry would not likely be a source of yeast contamination.

    Full Text Available Since the early Colonial times sugar production has been a key sector in the Peruvian export economy. This article analyzes its evolution as from the beginning of its modern phase by mid 19th Century, its consolidation in the Northern coastal region, and its concentration in scale-economy plants. The prosperity of this type of production contributed to the formation of both an oligarchy which governed the country until 1968, and the populist party (APRA and its electoral basis (the so-called «Aprista North». In the sixties Velasco Alvarado’s military revolution nationalized the sugar industry, which underwent structural changes leading to a serious crisis in the eighties that has not been overcome up-todate.

Some genus are considered to be significant producers of proteolytic and lipolytic enzymes. In this work, we analysed raw milk samples (n = 109 originated from 26 different suppliers from the area of North and Middle Moravia. The screening was performed from March 2007 to February 2008. The total bacterial counts (TBC ranged between 3.2 × 103 to 8.3 × 106 CFU/ml. The psychrotrophic bacterial counts (PBC ranged between 1.0 × 103 to 8.2 × 106 CFU/ml. Total of 48.62 % and 48.62 % of samples exceeded the hygienic limit in raw milk for TBC and PBC, respectively. The correlation between TBC and PBC was highly significant (r = 0.87.Significantly higher (P < 0.05 numbers of psychrotrophic microorganisms were detected in summer months. The identification of isolates was carried out and all strains were sreened for ability to produce proteolytic and lipolytic enzymes. The most commonly identified genus in raw milk was of the genus Pseudomonas. The ability to produce proteases or lipases was found at 76 % identified bacterial strains.

    Galimberti, Matteo; Marinoni, Nicoletta; Della Porta, Giovanna; Marchi, Maurizio; Dapiaggi, Monica

    2017-10-01

    Limestone represents the main raw material for ordinary Portland cement clinker production. In this study eight natural limestones from different geological environments were chosen to prepare raw meals for clinker manufacturing, aiming to define a parameter controlling the burnability. First, limestones were characterized by X-Ray Fluorescence, X-Ray Powder Diffraction and Optical Microscopy to assess their suitability for clinker production and their petrographic features. The average domains size and the microstrain of calcite were also determined by X-Ray Powder Diffraction line profile analysis. Then, each limestone was admixed with clay minerals to achieve the adequate chemical composition for clinker production. Raw meals were thermally threated at seven different temperatures, from 1000 to 1450 °C, to evaluate their behaviour on heating by ex situ X-Ray Powder Diffraction and to observe the final clinker morphology by Scanning Electron Microscopy. Results indicate the calcite microstrain is a reliable parameter to predict the burnability of the raw meals, in terms of calcium silicates growth and lime consumption. In particular, mixtures prepared starting from high-strained calcite exhibit a better burnability. Later, when the melt appears this correlation vanishes; however differences in the early burnability still reflect on the final clinker composition and texture.

  16. Sugar cane consumption on Rapanui (Easter Island) and the indicence of caries : evidence from stable isotope values of human bone

    International Nuclear Information System (INIS)

    Leach, B.F.; Quinn, C.J.; Seelenfreund, A.

    2017-01-01

    Pre-European people on Rapanui are known to have had a high rate of dental caries. One proposed explanation for this is that the people consumed a considerable amount of sugar cane, as a thirst quencher, since fresh water is scarce on the island. Human bone samples were analysed by isotope analysis to see if this explanation could be sustained. Results for three isotopes δ"1"3C, δ"1"5N and δ"3"4S were then used in a stochastic model to estimate the proportions of five main food types in the diet of these people. This indicated that daily consumption of dry raw sugar cane was only about 32 to 42 g per day. This is very low and sugar cane consumption is therefore unlikely to be the only cause of the high rate of dental caries. (author).

    Keeping in view of the demand and need for alternate energy source, especially liquid fuels and the availability of raw materials in Pakistan, we have carried out biochemical and technological studies for ethanol through fermentation of renewable substrates. Molasses and sugar cane have been used as substrate for yeast fermentation. Selected yeast were used in both batch and semi continuous fermentation of molasses. Clarified dilute molasses were fermented with different strains of Saccharomyces cerevisiae. Ethanol concentration after 64 hours batch fermentation reached 9.4% with 90% yield based on sugar content. During feed batch system similar results were obtained after a fermentation cycle of 48 hours resulting in higher productivity. Similarly carbohydrates in fruit juices and hydro lysates of biomass can be economically fermented to ethanol to be used as feed stock for other chemicals. (author)

    Some Particular areas contain natural radionuclide at levels much higher than those usually present in earth's crust. The radiological impact of the use of zirconium ore in zirconium industry is due to internal exposure of the lung by alpha particles and external exposure of the body by the gamma rays. The result of gamma spectrometry measurement of the concentrations of the natural radionuclide in zirconium industry is described. Materials and Methods: Gamma spectrometry system with a shielded high pure germanium (HPGe) detector connected to multi channel analyzer (MCA) was used to determine concentrations of natural radionuclide in about 45 samples of imported zirconium minerals, tiles, stone ware and waste sludge's of Iranian ceramic industry. Results: The 238 U concentration in the samples, ranging from 3000 to 10000 Bq Kg -1 , is higher than the concentration of both 232 Th (500-1800 Bq Kg -1 ), and 40 K (50-800 Bq Kg -1 ). The measured specific activities in the mineral showed that specific activity of baddeleyite is higher than that of zircon. The results of ceramic tiles show that the tiles usually contain small amount of zirconium compound. Conclusion: Due to relatively high concentration level of uranium in imported zirconium samples, specific regulations is necessary for zirconium compound used in ceramic industry

Remarkably, many of them have various known physiological functions and biotechnological applications in cosmetics, nutrition, and pharmaceutical industries. Also, they can be exploited as starting materials for synthesizing fascinating natural bioproducts with significant biological activities. Regrettably, most of the rare sugars are quite expensive, and their synthetic chemical routes are both limited and economically unfeasible due to expensive raw materials. On the other hand, their production by enzymatic means often suffers from low space-time yields and high catalyst costs due to hasty enzyme denaturation/degradation. In this context, biosynthesis of rare sugars with industrial importance is receiving renowned scientific attention, across the globe. Moreover, the utilization of renewable resources as energy sources via microbial fermentation or microbial metabolic engineering has appeared a new tool. This article presents a comprehensive review of physiological functions and biotechnological applications of rare ketohexoses and aldohexoses, including D-psicose, D-tagatose, L-tagatose, D-sorbose, L-fructose, D-allose, L-glucose, D-gulose, L-talose, L-galactose, and L-fucose. Novel in-vivo recombination pathways based on aldolase and phosphatase for the biosynthesis of rare sugars, particularly D-psicose and D-sorbose using robust microbial strains are also deliberated.

    Full Text Available As the fossil energy decrease such as petroleum and natural gas, that are encourages a lot of research to develop new sources of energy from renewable raw materials. One of the source is through reducing sugar (glucose and xylose obtained from coffee pulp waste; this is due to abundant production of coffee pulp every year reaching 743 kg/ha. In addition, this waste has not been used optimally and the cellulose and hemicellulose content of the coffee is high. The purpose of this study is to get the optimal operating condition for reducing sugar production from coffee pulp waste. The method used for optimization is Response Surface Methodology with Central Composite Design. The optimum operation condition obtained was pH 4.63 at 34ºC for 16.29 hours of hydrolysis. As a result, the predicted yield gained was 0.147 grams of reducing sugars / gram of cellulose+hemicellulose. The result indicates the gained yield was 0.137 grams of reducing sugars / gram of cellulose+hemicellulose.

    Chemical pretreatment of lignocellulosic biomass has been extensively investigated for sugar generation and subsequent fuel production. Alkaline pretreatment has emerged as one of the popular chemical pretreatment methods, but most attempts thus far have utilized NaOH for the pretreatment process. This study aimed at investigating the potential of potassium hydroxide (KOH) as a viable alternative alkaline reagent for lignocellulosic pretreatment based on its different reactivity patterns compared to NaOH. Performer switchgrass was pretreated at KOH concentrations of 0.5-2% for varying treatment times of 6-48 h, 6-24 h, and 0.25-1 h at 21, 50, and 121 °C, respectively. The pretreatments resulted in the highest percent sugar retention of 99.26% at 0.5%, 21 °C, 12 h while delignification up to 55.4% was observed with 2% KOH, 121 °C, 1 h. Six pretreatment conditions were selected for subsequent enzymatic hydrolysis with Cellic CTec2® for sugar generation. The pretreatment condition of 0.5% KOH, 24 h, 21 °C was determined to be the most effective as it utilized the least amount of KOH while generating 582.4 mg sugar/g raw biomass for a corresponding percent carbohydrate conversion of 91.8%.

    Full Text Available Sugar factories do achieve an efficient use of process water, but this process should be self-sufficient for consumption because these sugar factories have the special characteristic of having as its main raw material, sugar cane, which consists in approximately 70% of water Those condensed recovered will be the first option to recover process water and are aimed to the feeding of boilers. The quantities of the condensate types are dependent of the evaporator’s configuration, also the grade in that show up the vapor extractions. In this paper the fundamental aspects are described as for the use and handling of water in the process of sugar production. Also, important considerations are shown on the treatment systems of residual that are generated in these factories. The evaporation system is shown as the most important area for the handling of water in the process, in it, vegetable vapor takes place and it is used in other technological equipment. A major surplus of steam will be produced in this area if the process is more energetically efficient. It is shown through a balance of water that the process is self-sufficient for water consumption.

    installation 'Technologies for treatment and conditioning of radwaste' consists mainly of two bituminization plants and Bohunice Conditioning Centre (BSC RAW). Bituminization plants with capacity of 120 l/hour each are determined for bituminization of concentrates from VVER type NPPs and from A1 NPP Bohunice which are put into 200 l drums. The first one has been in operation since 1994 and its modification for discontinuous bituminization of ion-exchange resins and sludge is under way. The second one the commissioning of which has been finished successfully is now under licensing process for operation. At the end of 2001 total amount of concentrates treated by bituminization reached 941,7 m3. BSC RAW is the basic installed facility for final radwaste conditioning is. Besides cementation the technologies of incineration, fragmentation, high-pressure compaction as well as evaporation are used for radwaste treatment and conditioning at BSC RAW. Due to a complexity of commissioning of individual technologies, BSC RAW commissioning was divided in two phases which were realised in 2000. At the beginning of 2001 UJD issued the permission for BSC RAW operation on the basis of assessment of commissioning report. 144 pieces of FRC containers have been filled in during BSC RAW operation in 2001. As much as 51 t of solid radwaste and 3,9 m3 of liquid radwaste were incinerated, 85,7 t of solid radwaste were compacted and 186 m3 of concentrates were treated by cementation. Two treatment facilities are operated by VUJE Trnava. The bituminization plant has been out of operation during 2001 and incinerator with additional cementation facility have been used only for experimental purposes. National near surface repository in Mochovce is determined for the disposal of low and intermediate level short-living radwaste in special FRC containers as additional engineering barrier of repository. The repository construction was finished in November 1992. 52 containers with radwaste were disposed of

    The effect of particle size, method of particle size reduction (grinding, flaking, slicing) and alginate or Fibrimex(™) binding systems on processing properties of restructured beef were investigated. The size of semimembranosus muscles was reduced with a meat slicer, grinder or flaker (Comitrol) through machine openings that were 2, 4 and 8 mm in size. Bind of meat pieces in raw and cooked beef steakettes were measured. Sensory evaluation to determine the effect of method of size reduction on texture of beef steakettes was done only on steakettes manufactured with alginate. Beef steakettes manufactured with the alginate binding system had significantly (p meat for the manufacture of restructured beef steakettes resulted in a higher raw bind than did either grinding or flaking the meat. Significant (p meat was sliced than when it was ground or flaked. However, when Fibrimex was used, bind was stronger when sliced meat was used. The alginate system resulted in higher binds for cooked product when particle size was smaller but with the Fibrimex system bind was higher when particle sizes were larger. A consumer panel on alginate restructured steakettes showed no preference for the texture produced by the different methods of particle size reduction.

    Sugar cane is a major source of food and fuel worldwide. Biotechnology has the potential to improve economically-important traits in sugar cane as well as diversify sugar cane beyond traditional applications such as sucrose production. High levels of transgene expression are key to the success of improving crops through biotechnology. Here we describe new molecular tools that both expand and improve gene expression capabilities in sugar cane. We have identified promoters that can be used to drive high levels of gene expression in the leaf and stem of transgenic sugar cane. One of these promoters, derived from the Cestrum yellow leaf curling virus, drives levels of constitutive transgene expression that are significantly higher than those achieved by the historical benchmark maize polyubiquitin-1 (Zm-Ubi1) promoter. A second promoter, the maize phosphonenolpyruvate carboxylate promoter, was found to be a strong, leaf-preferred promoter that enables levels of expression comparable to Zm-Ubi1 in this organ. Transgene expression was increased approximately 50-fold by gene modification, which included optimising the codon usage of the coding sequence to better suit sugar cane. We also describe a novel dual transcriptional enhancer that increased gene expression from different promoters, boosting expression from Zm-Ubi1 over eightfold. These molecular tools will be extremely valuable for the improvement of sugar cane through biotechnology.

  14. Sugar Metabolism in Hummingbirds and Nectar Bats.

    Hummingbirds and nectar bats coevolved with the plants they visit to feed on floral nectars rich in sugars. The extremely high metabolic costs imposed by small size and hovering flight in combination with reliance upon sugars as their main source of dietary calories resulted in convergent evolution of a suite of structural and functional traits. These allow high rates of aerobic energy metabolism in the flight muscles, fueled almost entirely by the oxidation of dietary sugars, during flight. High intestinal sucrase activities enable high rates of sucrose hydrolysis. Intestinal absorption of glucose and fructose occurs mainly through a paracellular pathway. In the fasted state, energy metabolism during flight relies on the oxidation of fat synthesized from previously-ingested sugar. During repeated bouts of hover-feeding, the enhanced digestive capacities, in combination with high capacities for sugar transport and oxidation in the flight muscles, allow the operation of the "sugar oxidation cascade", the pathway by which dietary sugars are directly oxidized by flight muscles during exercise. It is suggested that the potentially harmful effects of nectar diets are prevented by locomotory exercise, just as in human hunter-gatherers who consume large quantities of honey.

    Full Text Available The objective of this research is to develop firms’ project manufacturing coordination. The development will be made by centralizing the manufacturing information flows in one system. To be able to centralize information, a deep user need assessment is required. After user needs have been identified, the existing system will be developed to match these needs. The theoretical background is achieved through exploring the literature of project manufacturing, development project success factors and different frameworks and tools for development project execution. The focus of this research is rather in customer need assessment than in system’s technical expertise. To ensure the deep understanding of customer needs this study is executed by action research method. As a result of this research the information system for project manufacturing coordination was developed to respond revealed needs of the stakeholders. The new system improves the quality of the manufacturing information, eliminates waste in manufacturing coordination processes and offers a better visibility to the project manufacturing. Hence it provides a solid base for the further development of project manufacturing.

    Problems related to the use of personal protective equipment (PPE), specially the use of protective gloves for the manual sugar cane cutting, motivated this research, made possible by a tripartite negotiation involving the Ministry of Labor, the Union of Rural Workers and the Employer's Association of sugarcane agribusiness. The main objective was to evaluate, from an ergonomics perspective, the impact of use of the gloves during the manual cane sugar cutting, raising questions on safety, effectiveness and comfort. The research was carried in a sugarcane industry of São Paulo for two seasons involving 47 workers who made a qualitative analysis of acceptance of four models of protective gloves. The methodology included the use of semi-structured interviews, questionnaires and field observations and the experimental determination of the coefficient of static friction developed between the gloves and the surfaces of the machete handle. The main results indicate the general inadequacy of the gloves currently used forcing the employees to improvise. Workers found the glove of leather and nylon scraping the best reported for comfort in use. The overall results highlight the problem of detachment of test standards for the manufacture of PPE, ignoring users and the activity to be performed.

    A conceptual design for an orbital factory sized to process 1.5 million metric tons per year of raw lunar fines into 0.3 million metric tons of manufacturing materials is presented. A conservative approach involving application of present earth-based technology leads to a design devoid of new inventions. Earth based counterparts to the factory machinery were used to generate subsystem masses and lumped parameters for volume and mass estimates. The results are considered to be conservative since technologies more advanced than those assumed are presently available in many areas. Some attributes of potential space processing technologies applied to material refinement and component manufacture are discussed.

  7. A balancing method for calculating a component raw involving CGF

    International Nuclear Information System (INIS)

    Kim, K.; Kang, D.; Yang, J.E.

    2004-01-01

    In this paper, a method called the 'Balancing Method' to derive a component RAW (Risk Achievement Worth) with basic event RAWs including a CCF (Common Cause Failure) RAW is summarized, and compared with the method proposed by the NEI (Nuclear Energy Institute) by mathematically checking the background on which the two methods are based. It is proved that the Balancing Method has a strong mathematically background. While the NEI method significantly underestimates the component RAW and is a little bit ad hoc in handling CCF RAW, the Balancing Method estimates the true component RAW very closely. Validity of the Balancing Method is based on the fact that if an component is out-of-service, it does not mean that the component is non-existent, but integrates the possibility that the component might fail due to CCF. The validity of the Balancing Method is proved by comparing it to the exact component RAW generated from the fault tree model

    Cordoba, Elizabeth; Aceves-Zamudio, Denise Lizeth; Hernández-Bernal, Alma Fabiola; Ramos-Vega, Maricela; León, Patricia

    2015-01-01

    Sugars regulate the expression of many genes at the transcriptional level. In Arabidopsis thaliana, sugars induce or repress the expression of >1800 genes, including the STP1 (SUGAR TRANSPORTER PROTEIN 1) gene, which encodes an H+/monosaccharide cotransporter. STP1 transcript levels decrease more rapidly after the addition of low concentrations of sugars than the levels of other repressed genes, such as DIN6 (DARK-INDUCED 6). We found that this regulation is exerted at the transcriptional level and is initiated by phosphorylatable sugars. Interestingly, the sugar signal that modulates STP1 expression is transmitted through a HEXOKINASE 1-independent signalling pathway. Finally, analysis of the STP1 5′ regulatory region allowed us to delimit a region of 309bp that contains the cis elements implicated in the glucose regulation of STP1 expression. Putative cis-acting elements involved in this response were identified. PMID:25281700

The disposal canister consist of two major components: the nodular graphite cast iron insert and overpack of oxygen-free copper. The manufacturing process for copper components begins with a cylindrical cast copper billet. Three different manufacturing processes i.e. pierce and draw, extrusion and forging are being developed, which produce a seamless copper tube or a tube with an integrated bottom. The pierce and draw process, Posiva's reference method, makes an integrated bottom possible and only the lid requires welding. Inserts for BWR-element are cast with 12 square channels and inserts for VVER 440-element with 12 round channels. Inserts for EPR-elements have four square channels. Casting of BWR insert type has been studied so far. Experience of casting inserts for PWR, which is similar to the EPR-type, has been got in co-operation with SKB. The report describes the processes being developed for manufacture of disposal canister components and some results of the manufacturing experiments are presented. Quality assurance and quality control in manufacture of canister component is described. (orig.)

    The availability of reasonably priced coating systems which meet the criteria of low-energy cure and minimum effluent pollution is of critical concern to the coatings industry. To appreciate the problems associated with radiation curable coatings, those manufacturing and utilizing these materials should be aware of their raw material compositions and the starting products from which they are derived. The utility and economics of ultraviolet coatings are also of prime interest. These topics are discussed, with emphasis on the photocurable polymers and their cross-linking monomers as well as the economics of this new technology in relation to energy cost savings. 7 references

    This paper discusses the occurrence of silicified tree trunks and stumps in the Boehlen brown coal field. The trees, mainly Taxodium and Sequoia 25 million years old, are located within the top brown coal seam of the deposit and present a major obstacle to excavator operation, together with other forms of so-called 'brown coal quartzite'. The quartz of the silicified trees occurs as opal, cryptocrystalline quartz and low temperature quartz. The separate removal and disposal of this wood as well as efforts made to use selected wood as raw material are briefly summarized. Various products for interior house decoration have been manufactured from the wood. (4 refs.)

    The raw materials for the cement industry are prospected - according to the recommendations of national authorities - by geophysical methods, too. These include not the determination of the deposit boundary, but also an estimation of the quality of limestone and clay from the point of cement manufacture. No forerunners of such tests exist, so new methods were elaborated. After 12 years of site tests it was found that the correlation between laboratory quality tests and certain geophysical parameters of clay deposits is fair but less close in case of limestone deposits.

    The authors explain how the optimum mixing time for the raw materials for glass manufacture can be determined with the aid of the radioactive tracer method. Basing themselves on measurements, they indicate the change in the degree of mixing of the individual components (soda (Na-24), sodium sulphate, coke (La-140) and bone meal (P-32) as a function of mixing time. The optimum degree of mixing and mixing time for dry and for wet mixing are determined. Finally, data for determining the permissible storage time of the mixture are given.

    Full Text Available Root rot diseases of sugar beet caused by Rhizoctonia solani (AG 2-2 IIIB and AG 2-2 IV, R. crocorum, Aphanomyces cochlioides, Phoma betae, Macrophomina phaeseolina, Fusarium oxysporum f.sp. radicis-betae, Pythium aphanidermatum Phytophthora drechsleri, Rhizopus stolonifer, R. arrhizus and Sclerotium rolfsii cause significant losses wherever sugar beets are grown. However, not all these soil-borne pathogens have been reported in all sugar beet production areas. Losses include reduced harvestable tonnage and reduced white sugar recovery. Many of these pathogens also cause post harvest losses in storage piles. Control for diseases caused by these pathogens include disease resistant cultivars, avoidance of stresses, cultural practices such as water management and the use of fungicides.

  18. Effect of seasonal variation on the composition and properties of raw milk destined for processing in the UK.

    2014-09-01

    The composition and physical properties of raw milk from a commercial herd were studied over a 1 year period in order to understand how best to utilise milk for processing throughout the year. Protein and fat levels demonstrated seasonal trends, while minerals and many physical properties displayed considerable variations, which were apparently unrelated to season. However, rennet clotting time, ethanol stability and foaming ability were subject to seasonal variation. Many significant interrelationships in physico-chemical properties were found. It is clear that the milk supply may be more suited to the manufacture of different products at different times of the year or even on a day to day basis. Subsequent studies will report on variation in production and quality of products manufactured from the same milk samples described in the current study and will thus highlight potential advantages of seasonal processing of raw milk.

  19. Development of Advanced Ceramic Manufacturing Technology

    Pujari, V.K.

    2001-04-05

    Advanced structural ceramics are enabling materials for new transportation engine systems that have the potential for significantly reducing energy consumption and pollution in automobiles and heavy vehicles. Ceramic component reliability and performance have been demonstrated in previous U.S. DOE initiatives, but high manufacturing cost was recognized as a major barrier to commercialization. Norton Advanced Ceramics (NAC), a division of Saint-Gobain Industrial Ceramics, Inc. (SGIC), was selected to perform a major Advanced Ceramics Manufacturing Technology (ACMT) Program. The overall objectives of NAC's program were to design, develop, and demonstrate advanced manufacturing technology for the production of ceramic exhaust valves for diesel engines. The specific objectives were (1) to reduce the manufacturing cost by an order of magnitude, (2) to develop and demonstrate process capability and reproducibility, and (3) to validate ceramic valve performance, durability, and reliability. The program was divided into four major tasks: Component Design and Specification, Component Manufacturing Technology Development, Inspection and Testing, and Process Demonstration. A high-power diesel engine valve for the DDC Series 149 engine was chosen as the demonstration part for this program. This was determined to be an ideal component type to demonstrate cost-effective process enhancements, the beneficial impact of advanced ceramics on transportation systems, and near-term commercialization potential. The baseline valve material was NAC's NT451 SiAION. It was replaced, later in the program, by an alternate silicon nitride composition (NT551), which utilized a lower cost raw material and a simplified powder-processing approach. The material specifications were defined based on DDC's engine requirements, and the initial and final component design tasks were completed.

  20. Respiration-Dependent Utilization of Sugars in Yeasts: a Determinant Role for Sugar Transporters

    OpenAIRE

    Goffrini, Paola; Ferrero, Iliana; Donnini, Claudia

    2002-01-01

    In many yeast species, including Kluyveromyces lactis, growth on certain sugars (such as galactose, raffinose, and maltose) occurs only under respiratory conditions. If respiration is blocked by inhibitors, mutation, or anaerobiosis, growth does not take place. This apparent dependence on respiration for the utilization of certain sugars has often been suspected to be associated with the mechanism of the sugar uptake step. We hypothesized that in many yeast species, the permease activities fo...

It seeks to fill a lacuna left by the concentration of monographs on the eighteenth and nineteenth centuries, suggesting that we know less about the history of sugar than we thought we did. Perhaps in no other single place is such a range of information on so wide an area presented in such detail for so early a period. Ranging from Iberia to the Caribbean and including consumption as well as production of sugar, with a nod to the slave trade and a very useful note on weights and currencies, this volume is a gold mine of information. It considers (briefly the theoretical meaning as well as the growing of this important crop, contrasting its production in Iberia with that on the Atlantic islands of Madeira and the Canaries, colonized by Iberian powers, and continuing the contrast with São Tomé, off the coast of Africa, and on to Brazil and the Spanish American empire before ending with the British in Barbados. In the transit, it of necessity considers and complicates the meaning of “sugar revolution” and shows how scholars using that term do not always mean the same thing. John McCusker and Russell Menard, for example, tackling a cornerstone of the traditional interpretation of the development of sugar, argue that there

    In our studies biodegradation of four variants of polystyrene was performed. We tested: raw material (PS), processed polystyrene (PSr), building insulation material (EPS) and food packaging boxes (PSp). Materials were characterized by means melt flow ratio (MFR), shore hardness and gloss. The biochemical assessment of macromolecules (proteins, lipids and sugars) in the mealworms organisms fed with tested forms of polystyrene allowed us to set how efficient and beneficial the biodegradation of types of polystyrene is. We also evaluated the variability of bacterial community in larval guts by the use of denaturing gradient gel electrophoresis (DGGE) on the bacterial DNA of 16S rRNA genes amplified in polymerase chain reaction (PCR). The results suggest that EPS and PSp polystyrene are the most digestible for T. molitor larvae. The metabolic degradation of polystyrene is probably strictly connected with the changes in biodiversity of gut bacteria.

    The obesity epidemic has focused attention on relationships of sugars and sugar-sweetened beverages (SSB) to cardiovascular risk factors. Here we report cross-sectional associations of SSB, diet beverages, sugars with blood pressure (BP) for UK and USA participants of the International Study of Macro/Micro-nutrients and Blood Pressure (INTERMAP). Data collected includes four 24-h dietary recalls, two 24-h urine collections, eight BP readings, questionnaire data for 2,696 people ages 40-59 from 10 USA/UK population samples. Associations of SSB, diet beverages, and sugars (fructose, glucose, sucrose) with BP were assessed by multiple linear regression. Sugar-sweetened beverage intake related directly to BP, P-values 0.005 to Sugar-sweetened beverage intake higher by 1 serving/day (355 ml/24-h) was associated with systolic/diastolic BP differences of +1.6/+0.8 mm Hg (both P sugar-sodium interactions: for individuals with above-median 24-h urinary sodium excretion, fructose intake higher by 2 SD (5.6 %kcal) was associated with systolic/diastolic BP differences of +3.4/+2.2 mm Hg (both P sugar-BP differences for persons with higher sodium excretion, lend support to recommendations that intake of SSB, sugars, and salt be substantially reduced.

    Full Text Available Sugar and sweet consumption have been popular and intrinsic to Indian culture, traditions, and religion from ancient times. In this article, we review the data showing increasing sugar consumption in India, including traditional sources (jaggery and khandsari and from sugar-sweetened beverages (SSBs. Along with decreasing physical activity, this increasing trend of per capita sugar consumption assumes significance in view of the high tendency for Indians to develop insulin resistance, abdominal adiposity, and hepatic steatosis, and the increasing “epidemic” of type 2 diabetes (T2DM and cardiovascular diseases. Importantly, there are preliminary data to show that incidence of obesity and T2DM could be decreased by increasing taxation on SSBs. Other prevention strategies, encompassing multiple stakeholders (government, industry, and consumers, should target on decreasing sugar consumption in the Indian population. In this context, dietary guidelines for Indians show that sugar consumption should be less than 10% of total daily energy intake, but it is suggested that this limit be decreased.

    Sugars are sweet-flavored carbohydrates that provide energy to the body. The adult brain uses about 140 g of glucose per day, amount which can represent up to 50 of the total number of carbohydrates consumed. In our country the sugar in food consumption pattern remains constant, while the consumption of soft drinks has increased in the past four years. The national survey of dietary intake of Spain (ENIDE, 2010-11) estimated that 20% of calories intake comes from carbohydrates called sugars. Sugar consumption has been associated with various pathologies (diabetes, obesity, tooth decay, cardiovascular disease) but these relationships are not consistent enough. Food information through nutritional labeling, including sugars present in food, pretend to protect the consumer health and to guarantee their right to information so they can make their own decisions with criterion. In view of different appraisals and existing studies, and above all, in the absence of a solid scientific evidence that concrete data on which make recommendations, the best nutritional advice for the general population could be a diet varied and balanced with food and nutrients from different sources, combining such a diet with exercise and physical activity. More specifically in terms of moderate consumption of sugar in the previous context of varied and balanced diet is perfectly compatible. Copyright © AULA MEDICA EDICIONES 2013.

    A systematic review of studies in humans was conducted to update evidence on the association between the amount of sugars intake and dental caries and on the effect of restricting sugars intake to caries to inform the updating of World Health Organization guidelines on sugars consumption. Data sources included MEDLINE, EMBASE, Cochrane Database, Cochrane Central Register of Controlled Trials, Latin American and Caribbean Health Sciences, China National Knowledge Infrastructure, Wanfang, and South African Department of Health. Eligible studies reported the absolute amount of sugars and dental caries, measured as prevalence, incidence, or severity. The review was conducted and reported in accordance with the PRISMA statement, and the evidence was assessed according to GRADE Working Group guidelines. From 5,990 papers identified, 55 studies were eligible – 3 intervention, 8 cohort, 20 population, and 24 cross-sectional. Data variability limited meta-analysis. Of the studies, 42 out of 50 of those in children and 5 out of 5 in adults reported at least one positive association between sugars and caries. There is evidence of moderate quality showing that caries is lower when free-sugars intake is caries risk throughout the life course. PMID:24323509

    2012-08-01

    Real-time spectroscopic methods can provide a valuable window into food manufacturing to permit optimization of production rate, quality and safety. There is a need for cutting edge sensor technology directed at improving efficiency, throughput and reliability of critical processes. The aim of the research was to evaluate the feasibility of infrared systems combined with chemometric analysis to develop rapid methods for determination of sugars in cereal products. Samples were ground and spectra were collected using a mid-infrared (MIR) spectrometer equipped with a triple-bounce ZnSe MIRacle attenuated total reflectance accessory or Fourier transform near infrared (NIR) system equipped with a diffuse reflection-integrating sphere. Sugar contents were determined using a reference HPLC method. Partial least squares regression (PLSR) was used to create cross-validated calibration models. The predictability of the models was evaluated on an independent set of samples and compared with reference techniques. MIR and NIR spectra showed characteristic absorption bands for sugars, and generated excellent PLSR models (sucrose: SEP 0.96). Multivariate models accurately and precisely predicted sugar level in snacks allowing for rapid analysis. This simple technique allows for reliable prediction of quality parameters, and automation enabling food manufacturers for early corrective actions that will ultimately save time and money while establishing a uniform quality. The U.S. snack food industry generates billions of dollars in revenue each year and vibrational spectroscopic methods combined with pattern recognition analysis could permit optimization of production rate, quality, and safety of many food products. This research showed that infrared spectroscopy is a powerful technique for near real-time (approximately 1 min) assessment of sugar content in various cereal products. © 2012 Institute of Food Technologists®

After manufacturing process, the implants were measured, microscopically and mechanical analyzed. Implants manufactured by AM can be an attractive option for surface coatings to improve the osseointegration process. The main advantages of customized implants made by AM process are: the precise adaptation to the region of implantation, better cosmesis, reduced surgical times and better performance over their generic counterparts. These medical manufacturing changes the way that the surgeons are planning surgeries and engineers are designing custom implant. AM process has eliminated the constraints of shape, size, internal structure and mechanical properties making it possible for fabrication of implants that conform to the physical and mechanical requirements of implantation according to CT images.

  1. Environmental Assessment of Different Cement Manufacturing ...

    Science.gov (United States)

    Due to its high environmental impact and energy intensive production, the cement industry needs to adopt more energy efficient technologies to reduce its demand for fossil fuels and impact on the environment. Bearing in mind that cement is the most widely used material for housing and modern infrastructure, the aim of this paper is to analyse the Emergy and Ecological Footprint of different cement manufacturing processes for a particular cement plant. There are several mitigation measures that can be incorporated in the cement manufacturing process to reduce the demand for fossil fuels and consequently reduce the CO2 emissions. The mitigation measures considered in this paper were the use of alternative fuels and a more energy efficient kiln process. In order to estimate the sustainability effect of the aforementioned measures, Emergy and Ecological Footprint were calculated for four different scenarios. The results show that Emergy, due to the high input mass of raw material needed for clinker production, stays at about the same level. However, for the Ecological Footprint, the results show that by combining the use of alternative fuels together with a more energy efficient kiln process, the environmental impact of the cement manufacturing process can be lowered. The research paper presents an analysis of the sustainability of cement production , a major contributor to carbon emissions, with respect to using alternative fuels and a more efficient kiln.

    The peanut supply chain in Malaysia is dominated by three main stakeholders (importers, manufacturers, retailers). The present study, aimed to determine the levels and critical points of aflatoxins and fungal contamination in peanuts along the supply chain. Specifically, two types of raw peanuts and six types of peanut-based products were collected (N = 178). Samples were analysed for aflatoxins by using High Performance Liquid Chromatography. Results revealed that the aflatoxins contamination was significantly higher (P≤0.05) in raw peanuts and peanut-based products from the retailers. However, there was no significant different (P≥0.05) in fungal contamination for both types of peanuts except for the total fungal count in raw peanuts from the retailers. Furthermore, raw peanut kernels from the retailers were the most contaminated ones ranged from contamination (0.3 - 3.6 log CFU/g) was relatively higher in raw peanuts compared to that of peanut-based products (0.6 - 2.7 log CFU/g). In conclusion, the manufacturers and retailers were the critical points for aflatoxins contamination in peanuts. However, fungal contamination was more critical in the raw peanuts compared to peanut-based products. The study was limited by a minimal number of samples from the importer. Therefore, further investigations on a larger sample size should be conducted to confirm the findings in this present study.

    Methods for forming an identifying mark in a structure are described. The method is used in conjunction with an additive manufacturing method and includes the alteration of a process parameter during the manufacturing process. The method can form in a unique identifying mark within or on the surface of a structure that is virtually impossible to be replicated. Methods can provide a high level of confidence that the identifying mark will remain unaltered on the formed structure.

    The impact of manufacturer back orders on the supply chain for pharmaceuticals in the institutional setting was studied. A questionnaire was distributed during May and June 2000 to 600 institutional pharmacies affiliated with a major national drug and supply group purchasing organization. The instrument included questions on basic institutional demographics, perceptions about the frequency of manufacturer back orders for pharmaceuticals, the quality of communication with manufacturers and wholesalers about back orders, the two most significant back orders that had occurred in the 12 months preceding the survey, and the reasons for and impact of back orders. A total of 170 usable surveys were returned (net response rate, 28.3%). Reported manufacturer back orders included an array of drug classes, including blood products, antimicrobials, antiarrhythmics, benzodiazepine antagonists, thrombolytics, corticosteroids, and antihypertensives. Respondents perceived significant back orders as increasing in frequency. Communication by manufacturers and wholesalers about back orders was reported to be relatively poor. A raw-material shortage was the most common reason given by manufacturers for back orders (36.5%), followed by a regulatory issue (23.2%). In most cases (92%), medical staff members had to be contacted, indicating an interruption in the normal drug distribution process. In over a third of instances, respondents stated that the back order resulted in less optimal therapy. A survey found that manufacturer back orders for pharmaceuticals were increasing in frequency and that information flow within the supply chain was insufficient to meet the needs of end users.

    have a higher alternative value when used as protein feed. Cereal screenings can be a suitable raw material provided that they only make up a minor proportion in mixtures with other more problem-free raw materials. - The scale of production has a great influence on production costs. In large-scale plants, the machinery and equipment, etc. are used much more efficiently than in smaller plants, which results in lower costs. - Small-scale pelletizing, both static and mobile, requires cheap raw materials and a high through-put to be profitable. In most cases, briquetting would be more commercially viable. - The energy consumption in manufacturing pellets from dry farm by-products is generally no higher than when moist sawdust is used as the raw material. More energy is admittedly required for cultivation and transport of farm by-products, but since there is no need for drying the total energy consumption is often lower. However, wet raw materials such as fresh Salix and distiller's waste can increase the total energy consumption

    The impact of sugar restriction on subsequent sugar intake by overweight adolescents is unknown. Our aim was to examine the effect of sugar restriction on subsequent ad libitum sugar intake by overweight adolescents and whether habitual sugar intake and impulsivity influence the effect of sugar restriction on subsequent sugar intake. This was an in-laboratory crossover feeding trial with sugar-exposure and sugar-restriction conditions. Eighty-seven overweight Latino and African-American adolescents underwent both meal conditions in two separate 8-hour in-laboratory visits. Participants had access to ad libitum snack trays for 3 hours after the condition-specific meals. Ad libitum sugar intake during the snack period was measured at each visit. Habitual sugar intake and impulsivity were assessed at baseline. Repeated measures analysis of covariance was used to examine the within-person effect of meal condition on ad libitum sugar intake. Mixed models were used to examine the moderating effects of habitual sugar intake and impulsivity on the meal condition-ad libitum sugar intake relationship. Participants consumed more ad libitum sugar during the snack period in the sugar-restriction condition than in the sugar-exposure condition (sugar restriction=78.63±38.84 g, sugar exposure=70.86±37.73 g; F=9.64, P=0.002). There was no relationship between habitual sugar intake and how much ad libitum sugar participants consumed during either condition. Higher impulsivity was associated with greater ad libitum sugar intake during both conditions (sugar restriction: b=.029, standard error=.01, Poverweight adolescents restricted from sugar intake consume greater amounts of sugar when they are later given access to high-sugar foods. Overweight adolescents with higher impulsivity appear to consume greater amounts of sugar regardless of previous levels of sugar consumption. Compensatory sugar intake and trait impulsivity may have implications for dietary interventions in this

    Statistics are given on the energy and raw materials (coal, oil, etc.) production and consumption levels in France in November 1997: primary energy total consumption has increased (mobile year) of 0.6%, at a slightly inferior rate than the rate since 3 years. Interior demand has varied depending on the energy: strong decrease for coal (- 9.3%), slight increase for petroleum products (+ 1.2%), markedly slowing down increase for gas (+ 1.4%) and moderate increase for electricity (+ 1.3%). An increase in the dollar exchange rate and a high level of oil and gas imports have induced a maintained high energy cost level with + 14% on one year, reaching 86.8 billions Francs, to be compared to 76.1 in November 1996

    In January, 1980, six out of 13 persons (46%) attending a party in a small northwest Florida town near the Gulf of Mexico became ill with Norwalk virus gastroenteritis after eating raw oysters. Symptoms experienced by the ill persons were principally nausea (100%), vomiting (83%) and diarrhea (50%) and were of brief duration. The symptom complex and epidemiology of Norwalk virus infection closely resemble the gastrointestinal illness commonly referred to as the 24-hour intestinal flu or "stomach flu." Norwalk virus infection was identified in this outbreak by application of a recently developed sensitive and specific serologic radioimmunoassay. Oysters from the incriminated batch had fecal coliform levels above recommended standards; however, recent studies of oyster-harvesting waters have shown only a weak correlation between fecal coliforms and the presence of enteric viruses. Further studies are needed to determine whether modifications of monitoring modalities for oyster-harvesting waters are needed.

    It would be helpful for students to know: a) How measurements are made in physical detectors, for example how a tracking chamber "sees" a charged particle or how a calorimeter measures energy. b) That physics processes result in photons, leptons, etc., which we then want to detect and analyze. These series of lectures describes the work that lies between the raw data taken by the detector elements and the physics variables used to study particular reactions. We start with an example analysis to show the kinds of information needed. We then describe the fitting process used to extract values from the observed patterns in typical detectors. This is followed by a discussion of the various problems of pattern recognition in tracking, calorimetry and particle identification detectors. The role of Monte Carlo simulation in understanding the quality of the obtained information is examined. We discuss how the use of "composite" observables is required due to what our instrumentation and reconstruction can achieve. Th...

    These series of lectures describes the work that lies between the raw data taken by the detector elements and the physics variables used to study particular reactions. We start by defining some simple physics variables of interest, then describe the fitting process used to extract values from the observed patterns in typical detectors. This is followed by a discussion of the various problems of pattern recognition in tracking, calorimetry and particle identification detectors. The process of calibration and alignment is surveyed, with emphasis on getting "reasonable" results in the absence of formally complete information. Finally, the role of Monte Carlo simulation in understanding the quality of the obtained information is examined. Throughout, we emphasize how the use of "composite" observables is required due to what our instrumentation and reconstruction can achieve.

    Full Text Available Sugar, which can be extracted from sugar cane and sugar beet, is one of the most important ingredients of food. Conducting more research to increase the extraction efficiency of sugar is necessary due to high production of sugar beet and its numerous processing units in northern Khorasan province. In this research, the effect of temperature, time and the frequency of ultrasonic waves on mechanical properties of sugar beet and its extraction rate of sugar in moisture content of 75% were studied. In this regard, an ultrasonic bath in laboratory scale was used. The studied parameters and their levels were frequency in three levels (zero, 25 and 45 KHz, temperature in three levels (25, 50 and 70 ° C and the imposed time of ultrasonic waves in three levels (10, 20 and 30 min. Samples were prepared using planned experiments and the results were compared with control sugar beet samples. A Saccharimeter was used to measure the concenteration of sugar in samples. Two different types of probe including semi-spherical end and the other one with sharpened edges were used to measure mechanical properties. The studied parameters of frequency, temperature and time showed significant effect on sugar extraction and their resulted effect in optimized levels revealed up to 56% increase in sugar extraction compared with control samples. The obtained values of elastic modulus and shear modulus showed a decreasing trend. The obtained values of total energy of rupture, the total energy of shear, the maximum force of rupture, and the yield point of rupture showed an increasing trend. The frequency had no significant effect on the yield point of rupture and shear force.

    ABSTRACT At this time, about 3,000 different viruses are recognized, but metagenomic studies suggest that these viruses are a small fraction of the viruses that exist in nature. We have explored viral diversity by deep sequencing nucleic acids obtained from virion populations enriched from raw sewage. We identified 234 known viruses, including 17 that infect humans. Plant, insect, and algal viruses as well as bacteriophages were also present. These viruses represented 26 taxonomic families and included viruses with single-stranded DNA (ssDNA), double-stranded DNA (dsDNA), positive-sense ssRNA [ssRNA(+)], and dsRNA genomes. Novel viruses that could be placed in specific taxa represented 51 different families, making untreated wastewater the most diverse viral metagenome (genetic material recovered directly from environmental samples) examined thus far. However, the vast majority of sequence reads bore little or no sequence relation to known viruses and thus could not be placed into specific taxa. These results show that the vast majority of the viruses on Earth have not yet been characterized. Untreated wastewater provides a rich matrix for identifying novel viruses and for studying virus diversity. Importance At this time, virology is focused on the study of a relatively small number of viral species. Specific viruses are studied either because they are easily propagated in the laboratory or because they are associated with disease. The lack of knowledge of the size and characteristics of the viral universe and the diversity of viral genomes is a roadblock to understanding important issues, such as the origin of emerging pathogens and the extent of gene exchange among viruses. Untreated wastewater is an ideal system for assessing viral diversity because virion populations from large numbers of individuals are deposited and because raw sewage itself provides a rich environment for the growth of diverse host species and thus their viruses. These studies suggest that

    Full Text Available Milk is one of the most important sources of human nutrition and because of high nutrient content; it is a very suitable medium for microbial growth and spoilage. Sometimes farmers cheat and add some additives to milk in order to cover the spoilage or other defects in milk. In this study 120 samples of bulk raw milk (10 samples each month were collected from dairy farms of Pakdasht under sterile condition and send to veterinary faculty of GarmsarUniversity. The following tests were done on each sample: Anti-microbial residues, residues milk acidity neutralizer, evaluation of sugar, formalin, Hydrogen peroxide, Salicylic acid and salt presence. Results were analyzed with Spss software and the results of the first six months of the year were compared statistically with the results of the second six months of the year. The mean of antimicrobial agents, milk acid neutralizer, formalin, hydrogen peroxide and salicylic acid showed no significant difference.

    The reduction of free or added sugar intake (sugars added to food and drinks as a sweetener) is almost universally recommended to reduce the risk of obesity-related diseases and dental caries. The World Health Organisation recommends intakes of free sugars of less than 10% of energy intake. However, estimating and monitoring intakes at the population level is challenging because free sugars cannot be analytically distinguished from naturally occurring sugars and most national food composition...

    Increase the intake of sugars among the inhabitants of developed countries is related to, among others, increasing consumption of non-alcoholic beverages, for which the relationship with the epidemic of obesity, particularly among children and adolescents, has been proven. The most frequently cited are non-alcoholic beverages, sweetened glucose-fructose syrup, ie. colas, tonics, ice teas, lemonades. Fruit drinks, fruit juices and nectars are commonly cited as a healthy alternative to non-alcoholic beverages and, however, we do not pay attention to the high content of sugars in these products. Determine the content of sugars in non-alcohollic beverages popular among children and adolescents. 80 non-alcoholic beverages such as cola, tonic, lemonade, ice tea, flavored waters, fruit juices, fruit nectars and fruit drinks. Evaluation of the content of monosaccharides and sucrose was performed by high performance liquid chromatography method (HPLC). In the tested non-alcohollic beverages, monosaccharides ie. glucose and fructose and the disaccharide sucrose were detected in different proportions. The product with the lowest content of the total sugars content was flavored water with lemon flavor based on the mineral water (2.72 g/100 ml). In the group of fruit juices, fruit nectars and fruit drinks highest sugars content have been reported (12.94 g/100 ml for aronia nectar and 12.76 g/100ml for the juice of pomegranate and grapes). Significant monosaccharides and sucrose content in the tested non-alcohollic beverages tends to claim that their manufacturers should be obliged to place warnings on the labels addressed to patients suffering from disorders of carbohydrate metabolism. Educational programs for children and adolescents with diabetes should include information about the content of a large amount of sugars in fruit products: fruit juices, fruit drinks and fruit nectar. © Polish Society for Pediatric Endocrinology and Diabetology.

  18. INVESTIGATION OF BACTERIOSTATIC PROPERTIES OF CHLORINATED COMPOUNDS FOR BEET-SUGAR INDUSTRY

    2014-01-01

    Full Text Available Summary. One of the major causes of decline in the quality of granulated sugar is bacterial contamination of sugar beet. This is due to the fact that the beet-sugar industry is a good object for the development of different groups of microorganisms. The main sources of infection of products of sugar manufacture can be soil, water, air, packaging, packaging materials, vehicles, clothing, equipment. The higher the beet contamination with the microorganisms, the more they decompose sucrose and secrete metabolic byproducts. In this regard, there is a need to reduce the negative impact of various groups of microorganisms and to minimize the loss of sucrose from decomposition. In accordance with the problem given the studies to determine the bacteriostatic properties of chlorinated compounds for sugar production were carried out. We used the cultivated fluid colonized with a pure culture of Leuconostoc mesenteroides and reagent treated as an object of study. In the experiments, we determined the accumulation of biomass of L. mesenteroides with nephelometric method by measuring the optical density of bacterial suspension. It was found out that after 24 hours of bacterial culturing the level of optical density in the control and active acidity were considerably higher compared with the sample treated with germicide. The number of microorganisms in the nutrient medium was determined by Vinogradsky-Shulgina-Brid’s. According to the study in the control is 1,7*10^16, in experiment with the introduction of the chlorinated compound it is 5,8*10^14. The experimental results show that the investigated chlorinated compound has bacteriostatic action against grampositive cocci saprophytic of L. mesenteroides and can be recommended for use in a sugar beet production.

    The effect of the hygienic quality of milk on changes in microbial counts and biogenic amine content was evaluated during ripening of goat cheeses manufactured from pasteurized and raw milks at 1, 14, 30, 60 and 90 d. The original milk, rennet, curd and whey were also included in the study. The pH, salt content and extent of proteolysis in the cheese were also evaluated. Spermidine and spermine were the main amines in raw milk, while they were minor amines in cheeses. Other amines increased markedly during ripening, tyramine being the main amine in cheese made from raw milk and cadaverine and putrescine in those produced from pasteurized milk. Enterobacteriaceae counts decreased during ripening whereas those of lactic acid bacteria increased, especially lactobacilli and enterococci. Cheese made from raw milk showed higher microbial counts during ripening than those made from pasteurized milk, especially for Enterobacteriaceae and enterococci, counts being 2 or 3 log units higher. Raw milk cheese showed remarkably higher biogenic amines compared with pasteurized milk cheeses. Therefore, pasteurization of milk causes a decrease in final biogenic amine content of cheese as a result of the reduction of its microbial counts.
