  1. Food irradiation and combination processes

    International approval of food irradiation is being given for the use of low and medium doses. Uses are being permitted for different categories of foods with maximum levels being set between 1 and 10 kGy. To maximize the effectiveness of these mild irradiation treatments while minimizing any organoleptic quality changes, combination processes of other technologies with irradiation will be useful. Combinations most likely to be exploited in optimal food processing include the use of heat, low temperature, and modified-atmosphere packaging. Because irradiation does not have a residual effect, the food packaging itself becomes an important component of a successful process. These combination processes provide promising alternatives to the use of chemical preservatives or harsher processing techniques. (author)

  2. Pallet irradiators for food processing

    McKinnon, R.G.; Chu, R.D.H.

    This paper looks at the various design concepts for the irradiation processing of food products, with particular emphasis on handling the products on pallets. Pallets appear to offer the most attractive method for handling foods from many considerations. Products are transported on pallets. Warehouse space is commonly designed for pallet storage and, if products are already palletized before and after irradiation, then labour could be saved by irradiating on pallets. This is also an advantage for equipment operation since a larger carrier volume means lower operation speeds. Different pallet irradiator design concepts are examined and their suitability for several applications are discussed. For example, low product holdup for fast turn around will be a consideration for those operating an irradiation 'service' business; others may require a very large source where efficiency is the primary requirement and this will not be consistent with low holdup. The radiation performance characteristics and processing costs of these machines are discussed. (author)

    The number of products being radiation processed is constantly increasing and today include such diverse items as medical disposable, fruits and vegetables, bulk spices, meats, sea foods and waste effluents. Not only do the products differ but also many products, even those within the same groupings, require different minimum and maximum radiation doses. These variations create many different requirements in the irradiator design. The design of Cobalt-60 radiation processing facilities is well established for a number of commercial applications. Installations in over 40 countries, with some in operation since the early 1960s, are testimony to the fact that irradiator design, manufacture, installation and operation is a well established technology. However, in order to design gamma irradiators for the preservation of foods one must recognize those parameters typical to the food irradiation process as well as those systems and methods already well established in the food industry. This paper discusses the basic design concepts for gamma food irradiators. They are most efficient when designed to handle a limited product density range at an established dose. Safety of Cobalt-60 transport, safe facility operation principles and the effect of various processing parameters on economics, will also be discussed. (Author)

    Teufel, P.

    1981-01-01

    The Joint FAO/IAEA/WHO Expert Committee on the wholesomeness of irradiated food which met in 1976 concluded after a detailed and critical review of the available information, that the microbiological aspects of food irradiation were fully comparable to those of conventional processes used in modern food technology. Processing of food by irradiation may be considered from the microbiological point of view as separate procedures: high dose treatment (> 10 kGy), for sterilisation (radappertization) and low dose treatment (< 10 kGy) for pasteurisation (radicidation, radurization), (for definitions see p. 43), disinfestation, or inhibition of sprouting. No public health hazards related to micro-organisms arise from high dose irradiation because this process results in commercially sterile products. On the other hand, it is important to consider the possible microbiological hazards when food is irradiated with a low dose. The microbiological implications relate to the natural radiation resistance of bacteria, yeasts, fungi and viruses or to the mutagenic effects of ionising radiation in micro-organisms. Both areas of concern were reviewed in detail by Ingram and Ingram and Farkas. (orig.)

  10. Food irradiation : estimates of cost of processing

    Krishnamurthy, K.; Bongirwar, D.R.

    1987-01-01

    For estimating the cost of food irradiation, three factors have to be taken into consideration. These are : (1) capital cost incurred on irradiation device and its installation, (2) recurring or running cost which includes maintenance cost and operational expenditure, and (3) product specific cost dependent on the factors specific to the food item to be processed, its storage, handling and distribution. A simple method is proposed to provide estimates of capital costs and running costs and it is applied to prepare a detailed estimate of costs for irradiation processing of onions and fish in India. The cost of processing onions worked out to be between Rs. 40 to 120 per 1000 Kg and for fish Rs 354 per 1000 Kg. These estimates do not take into account transparation costs and fluctuations in marketing procedures. (M.G.B.). 7 tables

    Economic constraints require that a food irradiation processing facility have a throughput of approximately 1 MGy ton/day (0.91 MGy m.t./day) requiring 3 MegaCuries (MCi) of cobalt-60 at each site. This requirement means that the total world amount of cobalt-60 would have to be increased by about 60 percent just to handle the California almond and raisin crop during peak season. It is doubtful that public opinion would allow the increased distribution of radioactive isotopes, with the resultant burden upon the transportation networks, as a price to be paid to eat irradiated food. Electric sources have characteristics that allow the production of more penetrating, uniform, and efficient radiation that is available from nuclear isotopes. The heart of the electric radiation source is the electron accelerator. At present, there are no accelerators commercially available that can meet the requirements for food irradiation processing. However, the U.S. Department of Defense-funded beam weapons programs have provided a very promising accelerator technology at the Lawrence Livermore National Laboratory. If this technology were to be commercialized, it appears that the required accelerators would be available for US$1.5 million apiece, and quite possibly for less than this amount. A conceptual design for a portable electric food irradiation processing machine is presented and analyzed for cost, assuming the required accelerators are available for $1.5 million each. It is shown that food can be processed for 1 kGy for a price of $5.98/ton ($6.59/m.t.)

    Statistics show that over forty per cent of the human population, a large portion of which come from the Third World, are suffering from hunger and malnutrition. While the solution to these problems depends to a great extent on the food production strategies of the various governments, equally important is the need to preserve existing food supply by reducing food and crop spoilage. It has been reported that estimated losses due to bacterial spoilage are heavy; those of highly perishable commodities such as fish and fishery products have been reported as amounting to thirty per cent of the total catch. An additional loss of five to ten per cent due to insects and microbes during lengthy periods of drying and/or storage has also been reported. After about thirty years of research, treatment with ionizing radiations has been proved to be a valuable potential tool for reducing post-harvest storage losses and for preserving quickly perishable food from deterioration. Since irradiation is a purely physical method of food conservation, it may for many purposes become the preferred method, for it is an environmentally clean process not tainted with the chemical residue problem, it is energy saving, and it can, in many cases, produce effects that cannot be achieved by conventional techniques (e.g. decontamination of frozen food without significant temperature changes, disinfestation and decontamination of food in bulk and packaged). The preservative effects of ionizing radiations can often be advantageously combined with effects of other physical or chemical agents. The resulting ''combination treatments'' may involve synergistic or cumulative action of the combination partners, leading to a decreased treatment requirement for one or both agents. This in turn may result in cost and/or energy savings and may bring about improvements in the sensory properties and bacteriological quality of the food thus treated.

    The applied dose range of irradiation processing of 4 kinds of pet foods had been studied. More than 92% microorganisms was inactive at the irradiation dose of 4 kGy, while more than 99% was inactive at 6 kGy. The microorganism load of irradiated pet food by 8 kGy met the requirement of national standards. The 10 kGy irradiation could sterilize the treated pet food. Salmonella had not been checked in irradiated or unirradiated samples. When irradiation dose ranged 4-10 kGy, there was no significant difference on contents of moisture, fat, protein, coarse fiber, carbohydrates, minerals (not including Calcium) or amino acids between irradiated and un-irradiated pet food. There was also no significant change on sensory quality of irradiated samples within this dose range. It is concluded that the recommended irradiation processing dose range for pet foods is 4-10 kGy.

    Globalization has led to rapid increases in international food trade. About 460 million metric tonnes of foodstuffs are traded annually of a value to the order of 300 billion US dollar. With such high trade figures, it is imperative to provide safe and nutritious foods to consumers and to minimize food losses due to spoilage. Food irradiation is a technology which has been under study and debate since fifties for the purpose of food preservation. This technology has been extensively reviewed and studied at international levels and by several countries and on the basis of these, a number of countries have permitted the use of irradiation for specified foods and are also applying it on commercial scale. In this paper, a review of the status and importance of this technology has been brought out to include the application of the technology and its perceived benefits, acceptance of the technology at the international level and by different countries including the scenario in India, the various types of concerns expressed by Governments as well as consumers and specific areas with regard to exports for which the technology would be beneficial.

    The film shows how irradiation of food by ionizing energy (gamma rays or beams of electrons) can help cut down post-harvest losses of food such as cereals, meat, fish and shellfish and fresh or dried fruits and vegetables. One quarter to one third of the total world food production is lost due to sprouting, destruction by insects and parasites, spoilage by micro-organisms such as bacteria and funghi, and premature ripening. Food contamination not only leads to economic problems but can also cause diseases such as trichinosis, toxoplasmosis, etc. The new technique of food irradiation has been studied by independent groups of experts whose evaluations without exception have been favourable. One of the main advantages is that there are no chemical residues. On the long run, food irradiation will help to assure world-wide food security

    Food irradiation can have a number of beneficial effects, including prevention of sprouting; control of insects, parasites, pathogenic and spoilage bacteria, moulds and yeasts; and sterilization, which enables commodities to be stored for long periods. It is most unlikely that all these potential applications will prove commercially acceptable; the extend to which such acceptance is eventually achieved will be determined by practical and economic considerations. A review of the available scientific literature indicates that food irradiation is a thoroughly tested food technology. Safety studies have so far shown no deleterious effects. Irradiation will help to ensure a safer and more plentiful food supply by extending shelf-life and by inactivating pests and pathogens. As long as requirement for good manufacturing practice are implemented, food irradiation is safe and effective. Possible risks of food irradiation are not basically different from those resulting from misuse of other processing methods, such as canning, freezing and pasteurization. (author)

    The food industry has used a variety of methods over the years to preserve or extend the shelf life of food. These have included cooking, packaging, smoking, chilling, freezing, dehydrating and using chemical additives. More recently, ionising radiation has been used to extend the storage life of foods. More research has been focussed on the effects of irradiation on foods than has been directed at any other form of food processing. This research has spanned 40 years and has been carried out in many countries. Food irradiation can be used to: (a) inhibit the sprouting of vegetables; (b) delay the ripening of fruits; (c) kill insect pests in fruit, grains or spices; (d) reduce or eliminate food spoilage organisms; (e) reduce food poisoning bacteria on some meats and sea food products. This chapter includes sections on the historical background; general aspects of radiation; scientific, technological, microbiological and toxicological aspects of food irradiation; nutritional aspects of food irradiation; consumer attitudes; current status and legislation; labelling. It concludes that the relatively new process of preserving food by irradiation compliments rather than competes with the presently available traditional methods. (author)

    Food preservation by irradiation is one part of Eisenhower's Atoms for Peace program that is enjoying renewed interest. Classified as a food additive by the Food, Drug, and Cosmetic Act of 1958 instead of a processing technique, irradiation lost public acceptance. Experiments have not been done to prove that there are no health hazards from gamma radiation, but there are new pressures to get Food and Drug Administration approval for testing in order to make commercial use of some radioactive wastes. Irradiation causes chemical reactions and nutritional changes, including the destruction of several vitamins, as well as the production of radiolytic products not normally found in food that could have adverse effects. The author concludes that, lacking epidemiological evidence, willing buyers should be able to purchase irradiated food as long as it is properly labeled

    Food can be provided with extra beneficial properties by physical processing. These benefits include a reduced possibility of food poisoning, or an increased life of the food. We are familiar with pasteurisation of milk, drying of vegetables, and canning of fruit. These physical processes work because the food absorbs energy during treatment which brings about the changes needed. The energy absorbed in these examples is heat energy. Food irradiation is a less familiar process. It produces similar benefits to other processes and it can sometimes be applied with additional advantages over conventional processing. For example, because irradiation causes little heating, foods may look and taste more natural. Also, treatment can take place with the food in its final plastic wrappers, reducing the risk of re-contamination. (author). 1 ref., 4 figs., 1 tab

    A worldwide standard on food irradiation was adopted in 1983 by codex Alimentarius Commission of the Joint Food Standard Programme of the Food and Agriculture Organization (FAO) of the United Nations and The World Health Organization (WHO). As a result, 41 countries have approved the use of irradiation for treating one or more food items and the number is increasing. Generally, irradiation is used to: food loses, food spoilage, disinfestation, safety and hygiene. The number of countries which use irradiation for processing food for commercial purposes has been increasing steadily from 19 in 1987 to 33 today. In the frames of the national programme on the application of irradiation for food preservation and hygienization an experimental plant for electron beam processing has been established in Inst. of Nuclear Chemistry and Technology. The plant is equipped with a small research accelerator Pilot (19 MeV, 1 kW) and industrial unit Electronika (10 MeV, 10 kW). On the basis of the research there were performed at different scientific institutions in Poland, health authorities have issued permissions for irradiation for; spices, garlic, onions, mushrooms, potatoes, dry mushrooms and vegetables.

    Processing of food with low levels of radiation has the potential to contribute to reducing both spoilage of food during storage - a particular problem in developing countries - and the high incidence of food-borne disease currently seen in all countries. Approval has been granted for the treatment of more than 30 products with radiation in over 30 countries but, in general, governments have been slow to authorize the use of this new technique. One reason for this slowness is a lack of understanding of what food irradiation entails. This book aims to increase understanding by providing information on the process of food irradiation in simple, non-technical language. It describes the effects that irradiation has on food, and the plant and equipment that are necessary to carry it out safely. The legislation and control mechanisms required to ensure the safety of food irradiation facilities are also discussed. Education is seen as the key to gaining the confidence of the consumers in the safety of irradiated food, and to promoting understanding of the benefits that irradiation can provide. (orig.)

    International Nuclear Information System (INIS)

    Kampelmacher, E.H.

    1981-01-01

    Food-borne diseases are an increasing health hazard throughout the world. Some of these diseases, such as salmonellosis, staphylo-entero-toxicosis, botulism, vibriosis and parasitic infections have always played an important role, whereas some other food-borne pathogens, such as Campylobacter, Vibrio parahaemolyticus and toxin-producing fungi have only been recognised in recent decades. Changing food-production methods, food processing and especially food habits, together with the enormous trade in foods and feeds from one part of the world to the other, are responsible for the increase of these diseases. To meet this situation, prevention and control of food-borne diseases, which involve large groups of persons and play a major socio-economic role in many parts of the world, are of utmost importance. In prevention and control programmes food irradiation can be applied successfully and may solve some of the food and feed contamination problems. The author summarizes to-day's most important food-borne diseases, the type of foods which are responsible for infections in man and animals, and the commodities in which low-dose food irradiation may be of great value in preventing these diseases. The advantages of irradiation versus the use of chemical additives and pesticides and with respect to the prevention of cross-contamination (which plays a very important role in initiating food-borne diseases) by pre-packaging, are emphasized. The required irradiaton doses to eliminate or reduce the number of pathogenic organisms which may be present in foods, the problem of radioresistance and the acceptability of irradiated food are discussed. Finally to-day's situation of irradiated foods with regard to legislation, consumers' information and economic feasibility is summarized. (author)

    In the irradiation process, absorbed dose is the key parameter that must be controlled. In general, the minimum absorbed dose needed to accomplish a desired effect, such as insect disinfestation or pathogen reduction, is already known from previous research, and is often prescribed by government regulations. The irradiation process is effective, however, only if the food can tolerate this dose without experiencing unwanted changes in flavor or appearance. The dose that food can tolerate often depends on such things as the variety of the fruit or vegetable, where it was grown, the season in which it was harvested and the length of time between harvesting and irradiation. Once the minimum and maximum doses are established, the irradiator operator must make sure that these dose limits are not exceeded. First, a dose mapping using many dosimeters must be undertaken to determine the locations of the minimum and maximum dose in the overall process load. From then on, the process load must always be the same, and, as a key step in the overall process control, dosimeters need to be placed from time to time only at the minimum or maximum locations. The dosimeters must be calibrated and directly trackable to national or international standards, and a fool-proof method of labelling and segregating irradiated from unirradiated product must be used. Radiation sensitive indicators that may help identify irradiated from unirradiated food should not be relied upon, and are not a substitute fro proper dosimetry. (Author)

    1981-01-01

    Irradiation can facilitate preservation and distribution of food; it can reduce the need for chemical additives and pesticides; and it can reduce the overall use of energy. Often, industry must make changes because of seasonal variation in supply. Application of food irradiation will be difficult, therefore, unless industry can adjust to these changes, which require a broad clearance, or that food irradiation be cleared as a process. Basic to such broad clearance is a thorough understanding of the changes that take place so that the results of animal feeding studies can be extrapolated to foods similar to those used in the animal feeding studies. Such extrapolation is sometimes called chemiclearance. The extensive research on the safety of irradiated foods is summarized and the following major categories discussed: (a) theory of interaction of radiation with food; (b) chemical analysis of the radiolytic products and measurements of their yields as a function of the chemical composition of the food, temperature, dose, and dose-rates; (c) toxicological evaluation of the radiolytic compounds; and (d) toxicological evaluation of short-term and long-term animal feeding studies, mutagenicity studies, teratogenicity studies, and anti-metabolite studies.

    The article explains what radiation does to food to preserve it. Food irradiation is of economic importance to Canada because Atomic Energy of Canada Limited is the leading world supplier of industrial irradiators. Progress is being made towards changing regulations which have restricted the irradiation of food in the United States and Canada. Examples are given of applications in other countries. Opposition to food irradiation by antinuclear groups is addressed

    Food irradiation has become a matter of topical interest also in the Federal Republic of Germany following applications for exemptions concerning irradiation tests of spices. After risks to human health by irradiation doses up to a level sufficient for product pasteurization were excluded, irradiation now offers a method suitable primarily for the disinfestation of fruit and decontamination of frozen and dried food. Codex Alimentarius standards which refer also to supervision and dosimetry have been established; they should be adopted as national law. However, in the majority of cases where individual countries including EC member-countries so far permitted food irradiation, these standards were not yet used. Approved irradiation technique for industrial use is available. Several industrial food irradiation plants, partly working also on a contractual basis, are already in operation in various countries. Consumer response still is largely unknown; since irradiated food is labelled, consumption of irradiated food will be decided upon by consumers.

    The Queensland Government has given its support the establishment of a food irradiation plant in Queensland. The decision to press ahead with a food irradiation plant is astonishing given that there are two independent inquiries being carried out into food irradiation - a Parliamentary Committee inquiry and an inquiry by the Australian Consumers Association, both of which have still to table their Reports. It is fair to assume from the Queensland Government's response to date, therefore, that the Government will proceed with its food irradiation proposals regardless of the outcomes of the various federal inquiries. The reasons for the Australian Democrats' opposition to food irradiation which are also those of concerned citizens are outlined

    This paper reviews researches, commentaries, and conference and public records of food irradiation, published mainly during the period 1987-1989, focusing on the current conditions of food irradiation that may pose not only scientific or technologic problems but also political issues or consumerism. Approximately 50 kinds of food, although not enough to fill economic benefit, are now permitted for food irradiation in the world. Consumerism is pointed out as the major factor that precludes the feasibility of food irradiation in the world. In the United States, irradiation is feasible only for spices. Food irradiation has already been feasible in France, Hollands, Belgium, and the Soviet Union; has under consideration in the Great Britain, and has been rejected in the West Germany. Although the feasibility of food irradiation is projected to increase gradually in the future, commercial success or failure depends on the final selection of consumers. In this respect, the role of education and public information are stressed. Meat radicidation and recent progress in the method for detecting irradiated food are referred to. (N.K.) 128 refs

    Food irradiation has been the subject of concern and controversy for many years. The advantages of food irradiation include the reduction or elimination of dangerous bacterial organisms, the control of pests and insects which destroy certain foods, the extension of the shelf-life of many products, for example fruit, and its ability to treat products such as seafood which may be eaten raw. It can also replace existing methods of treatment which are believed to have hazardous side-effects. However, after examining the evidence produced by the proponents of food irradiation, the author questions whether it has any major contribution to make to the problems of foodborne diseases or world food shortages. More acceptable solutions, he suggests, may be found in educating food handlers to ensure that hygienic conditions prevail in the production, storage and serving of food. (author)

    In order to determine radial decay behaviors of γ-irradiated food, we analyzed radicals in the food using ESR. We detected the ESR signal of specimens just several minutes after irradiation. The singlet signal intensity at g=2.0, originated from organic free radicals was increased as followed by the increasing radiation dose. Singlet signal intensity that increased by γ-irradiation was decreased with time. The phenomena of decay of the ESR singlet signal showed two phase that are rapid decay and slow decay. It was suggested that those two phase decay is due to at least the two radical species. Also we concluded that after three hours of radiation treatment long life radical as ESR signal intensity was detected in irradiated specimen; black pepper, green coffee bean and ginseng, showed the same decay phenomena. But the signal intensity of irradiated black pepper was three times larger than that of irradiated green coffee bean and irradiated ginseng. (author)

    The detection of radiation-specific degradation products in fat has become an established method which has successfully been applied to egg products. This study is making evident the detectability of irradiated eggs as an ingredient of specified processed foods. Tart layers were produced from both irradiated and non-irradiated liquid whole egg. When the fat components were isolated from the tart layers and investigated by GC/MS, the presence of irradiated eggs could clearly be shown. While the radiation-induced hydrocarbons and 2-alkylcyclobutanones could not be found in unirradiated samples, tart layers from irradiated eggs contained these substances. Especially for the hydrocarbons a satisfying correlation between radiation dose and concentration could be observed. The concentrations of radiation-induced compounds were generally lower in the tart layers than in the liquid egg samples they had been produced from. (orig.) [de

    The associations between the dosimetry concepts, Minimum absorbed dose (Dsub(min)), maximum absorbed dose (Dsub(max), and average dose and median dose are investigated for the case of a large cobalt-60 plaque source irradiating homogeneous bulk product in a two-pass, two-sided irradiation. It is assumed that to a first approximation the intensity of radiation decreases exponentially with the depth, t, in the product. A series of mathematical relationships is derived for the average dose, the maximum and minimum dose, the median dose [defined as (Dsub(maX) + Dsub(min)/2], and the uniformity ratio (defined U.R. = (Dsub(max)/Dsub(min). The relationships are derived in terms of a constant D 0 (the dose on the surface of the products in the pass close to the source) and the relaxation length (μt) of the radiation in the product. Since the uniformity ratio and other dose parameters can be calculated for certain chosen values of μt, the individual values Dsub(min) to Dsub(max) into 10 equal fractions, the amount of product irradiated to each of the fractions is calculated and it is shown that, independent of the value of U.R., about a third of the product receives a dose in the first fraction above Dsub(min). It is also shown that for a given median dose, the average dose decreases as U.R. increases. The calculated dose relationships are confirmed by measurement in homogeneous dummy product, using the lyoluminescence of glutamine to measure dose. The implications of these results for the regulation of the food irradiation process and for the design of irradiation facilities are discussed. (author)

    In spring and early summer 1992, a number of irradiated egg products were illegally imported into Germay. To prove the irradiation of these egg products, mainly combined gas chromatography-mass spectrometry was applied. With this present study we wanted to answer the question if we were also able to detect the use of irradiated eggs in processed foods. The processed food we chose to produce and to investigate was a tart layer. For this product, dilution effects are of minor importance as no extra fat was added. Thus, the layers' fat almost exclusively came from the eggs. To study the influence of emulsifiers, we produced batters both with and without adding an emulsifer. The unsaturted hydrocarbons C14:1, C16:3, C16:2, C17:2, and C17:1 served as markers for an irradiation. In the non-irradiated egg samples and in the tart layers produced from them, these compounds could not be detected (or in some cases only in small amounts). They were, however, detectable in all irradiated samples. DCB could be found in all irradiated egg samples and in the tart layers that were baked from irradiated eggs. It was not present in non-irradiated eggs and in tart layers produced from them. (orig./Vhe)

    Markedly improved measures of hygiene, including those attaining generally accepted GMP, are effective in reducing the contamination rate markedly, without completely eliminating the pathogens concerned though. Attempts to identify contaminated consignments by sampling examination were demonstrated to be unsuccessful, even when linked to certification by producing countries. The only practicable solution of this serious health problem has to rely on terminal processing for safety, as introduced in the twenties in the dairy industry and somewhat later in the manufacture of egg products. Gamma irradiation (radicidation) at a level of <= 4 kGy was found to be most effective for a more than adequate degree of elimination of pathogens as judged by Risk Analysis. Radicidation for this purpose did not entail immediate flora changes or even shifts in the microbial community structure secondary to slight temperature abuse, that presented any health risk. Neither were organisms isolated that could not be identified with types customarily encountered in fresh or processed food. Consequently, health authorities and the food industry alike henceforth have means available to protect consumers against the perennial food-transmitted enteric infectious diseases by the application of low amounts of ionizing energy. They should not postpone these or similar measures of intervention unnecessarily because otherwise they risk being blamed by history for being reprehensibly over-anxious

    Several kinds of spices and processed food namely onion, garlic, turmeric, red chillies, black pepper, cloves, cinnamon, simple curry, meat curry, curry prepared from irradiated onions and potatoes and curry from irradiated fish were tested for cytotoxocity and mutagenicity. Onion root tips were used in the studies of cytotoxicity. Pseudomonas fluorescens strain NCTC-9428, a streptomycin-sensitive strain, was used as the test organism in mutagenicity studies. Wide range of cytoxicity was observed in all spices and food tested, varying from 48% abnormality in root tips in black pepper to 97.7% in garlic extract. The degrees of cytotoxic abnormality of irradiated potatoes and onions appeared to be lower than in their control counterparts. The average percentages of cytotoxic abnormality in curry prepared from irradiated fish and the one prepared from irradiated potatoes and onions, at their original concentration, were 95.92% and 99.5% resp. Digesting curry prepared from irradiated potatoes and onions with bile salts appeared to show some detoxification characteristics. The mutation rate of Pseudomonas fluorescens grown in media containing unirradiated spice extract was significantly higher than in the control (media without spice extract). However, the mutation rate of an extract of irradiated onions (10 krad) showed no difference from the control. There was no difference in the mutation rate on extracts of curry prepared from irradiated onions and potatoes from the one prepared from unirradiated onions and potatoes

    Various aspects of food treatment by cobalt 60 or caesium 137 gamma radiation are reviewed. One of the main applications of irradiation on foodstuffs lies in its ability to kill micro-organisms, lethal doses being all the lower as the organism concerned is more complex. The effect on parasites is also spectacular. Doses of 200 to 300 krad are recommended to destroy all parasites with no survival period and no resistance phenomenon has ever been observed. The action of gamma radiation on macromolecules was also investigated, the bactericide treatment giving rise to side effects by transformation of food components. Three examples were studied: starch, nucleic acids and a whole food, the egg. The organoleptic aspect of irradiation was examined for different treated foods, then the physical transformations of unpasteurized, heat-pasteurized and radio-pasteurized eggs were compared. The report ends with a brief analysis of the toxicity and conditions of application of the treatment.

    Irradiation is a physical process for treating food and as such it is comparable to other processing techniques such as heating or freezing foods for preservation. The energy level used in food irradiation is always below that producing radioactivity in the treated food, hence this aspect can be totally excluded in wholesomeness evaluations. Water is readily ionized and may be the primary source of ionization in foods with secondary effects on other molecules, possibly more a result of water ionization than of direct hits. In the presence of oxygen, highly reactive compounds may be produced, such as H, H 3 0+ and H 2 O 2 . Radiation at the energy flux levels used for food (<2 MeV) does not induce radioactivity. Food irradiation applications are already technically and economically feasible and that food so treated is suitable for consumption. Food irradiation techniques can play an important role for an improved preservation, storage and distribution of food products. (author)

    Food irradiation is used to improve the safety of food by killing insects and microorganisms, to inhibit sprouting in crops such as onions and potatoes and to control ripening in agricultural produce. In order to prevent re-infestation and re-contamination it is essential that the food is suitably packed. Consequently, the packaging material is irradiated whilst in contact with the food, and it is important that the material is resistant to radiation-induced changes. In this paper the nature of the irradiation process is reviewed briefly, together with the known effects of irradiation on packaging materials and their implications for the effective application of food irradiation. Recent research carried out at the Leatherhead Food RA on the possibility of taint transfer into food is described. (author)

    Since 1967 research activities on food irradiation in Japan have been carried out under the National Food Irradiation Programme by the Japanese Atomic Energy Commission. The programme has been concentrated on the technological and economical feasibility and wholesomeness testings of seven irradiated food items of economic importance to the country, i.e. potatoes, onions, wheat, rice, 'kamaboko' (fish-paste products), 'Vienna' sausages and mandarin oranges. By now most studies, including wholesomeness testings of these irradiated food items, have been completed. In Japan, all foods or food additives for sale are regulated by the Food Sanitation Law enforced in 1947. Based on studies made by the national programme, irradiated potatoes were given 'unconditional acceptance' for human consumption in 1972. At present, irradiated potatoes are the only food item which has so far been approved by the Minister of Health and Welfare. Unless the Minister of Health and Welfare has declared that items are not harmful to human health on obtaining comments from the Food Sanitation Investigation Council, no irradiated food can be processed or sold. In addition, the import of irradiated foodstuffs other than potatoes from foreign countries is prohibited by law.

    Food irradiation offers tremendous potential as a means of food preservation, particularly for developing countries. Irradiating food on a commercial scale has distinct advantages. Through irradiation, the keeping quality of a variety of food will be increased, insect infestation will be controlled, and dangerous intestinal pathogens will be eliminated. It will also facilitate export of food, which will aid national economic development, provide employment opportunities and foster the development of personnel trained in the technology. While food irradiation may be of importance and use in developing countries, it is equally important that developing countries are not used as `testing grounds` for commercial food irradiation. By and large, public reluctance to accept food irradiation is deep-rooted. Fears need to be allayed through exposure to research results and extensive talks by experts and individuals from research institutions and the United Nations. If such attempts fail, it may be necessary for the government to embark on a program of introducing alternative food processes or technologies, e.g. food dehydration, fermentation, thermal or chemical treatments. In the eventual adoption of food irradiation, inspection of plants and manufacturing and distribution practices, monitoring of production lines, and testing of final product samples will be necessary

If such attempts fail, it may be necessary for the government to embark on a program of introducing alternative food processes or technologies, e.g. food dehydration, fermentation, thermal or chemical treatments. In the eventual adoption of food irradiation, inspection of plants and manufacturing and distribution practices, monitoring of production lines, and testing of final product samples will be necessary

  9. Induction and reversion process of molecular and cytological alterations after highly irradiated food ingestion in mice

    The molecular and cytological alterations induced in a mammal (Mus musculus) fed ad libitum with a balanced pellet diet irradiated with 50 KGy gamma radiation from weaning, for different periods, are analyzed. The transient chromosomal changes that recall tumor-like phenomena could be the expression of the damage and repair processes induced by changed molecules present in irradiated food. The reversible alterations of DNA structure and cytoplasmatic soluble proteins observed in mice fed with irradiated pellet diet could be interpreted as a result of the enhancement of the repair processes which could also explain the significant increase of the radioresistance of DNA found at 200 days after irradiated food ingestion. Finally, our results would suggest an induction of a pseudo-neoplasia due to a prolongated and exclusive ingestion of food irradiated with sterilizing gamma dose. Moreover, the maintenance of the irradiated diet induce the reversion of the observed phenomena by an eventual activation of the repair mechanisms. (Author)

  10. Food irradiation in perspective

    Henon, Y.M.

    1995-01-01

    Food irradiation already has a long history of hopes and disappointments. Nowhere in the world it plays the role that it should have, including in the much needed prevention of foodborne diseases. Irradiated food sold well wherever consumers were given a chance to buy them. Differences between national regulations do not allow the international trade of irradiated foods. While in many countries food irradiation is still illegal, in most others it is regulated as a food additive and based on the knowledge of the sixties. Until 1980, wholesomeness was the big issue. Then the ''prerequisite'' became detection methods. Large amounts of money have been spent to design and validate tests which, in fact, aim at enforcing unjustified restrictions on the use of the process. In spite of all the difficulties, it is believed that the efforts of various UN organizations and a growing legitimate demand for food safety should in the end lead to recognition and acceptance.

    Many foods carry microorganisms that may have serious consequences for the health of the consumer. There is thus often a need for processing to eliminate the resulting health hazards. Concern has been expressed that treatments, especially irradiation, might be applied to clean up food that has not been hygienically processed. Adherence to good manufacturing practice can greatly assist food processors to ensure food quality and safety. Figs

  19. Development of shelf stable, processed, low acid food products using heat-irradiation combination treatments

    Minnaar, A.

    1998-01-01

    The amount of ionizing irradiation needed to sterilize low acid vegetable and starch products (with and without sauces) commercially impairs their sensorial and nutritive qualities, and use of thermal processes for the same purpose may also have an adverse effect on the product quality. A systematic approach to the establishment of optimized combination parameters was developed for heat-irradiation processing to produce high quality, shelf stable, low acid food products. The effects of selected heat, heat-irradiation combination and irradiation treatments on the quality of shelf stable mushrooms in brine and rice, stored at ambient temperature, were studied. From a quality viewpoint, use of heat-irradiation combination treatments favouring low irradiation dose levels offered a feasible alternative to thermally processed or radappertized mushrooms in brine. However, shelf stable rice produced by heat-irradiation combination treatments offered a feasible alternative only to radappertized rice from the standpoint of quality. The technical requirements for the heat and irradiation processing of a long grain rice cultivar from the United States of America oppose each other directly, thereby reducing the feasibility of using heat-irradiation combination processing to produce shelf stable rice. The stability of starch thickened white sauces was found to be affected severely during high dose irradiation and subsequent storage at ambient temperature. However, use of pea protein isolate as a thickener in white sauces was found to have the potential to maintain the viscosity of sauces for irradiated meat and sauce products throughout processing and storage.

    This fact sheet considers the microbiological safety of irradiated food, with especial reference to Clostridium botulinum. Irradiated food, as food treated by any ''sub-sterilizing'' process, must be handled, packaged and stored following good manufacturing practices to prevent growth and toxin production of C. botulinum. Food irradiation does not lead to increased microbiological hazards, nor can it be used to save already spoiled foods. 4 refs

    Although irradiation is being investigated for the last more than 50 years for the application in preservation of food, it has not yet been exploited commercially in some countries like India. No other food processing technique has undergone such close scrutiny. There are many advantages to this process, which few others can claim. The temperature remains ambient during the process and the form of the food does not change resulting in very few changes in the sensory and nutritive quality of the food product. At the same time the microorganisms are effectively destroyed. Most of the spoilage and pathogenic organisms are sensitive to irradiation. Fortunately, most governments are supportive for the process and enacting laws permitting the process for foods

    In discussing the need for food irradiation the author examines the problems that arise in processing foods of different kinds: spices, meat, fruits and vegetables. It is demonstrated that the relatively low dose of radiation required to eliminate the reproductive capacity of the pest can be tolerated by most fruits and vegetables without damage. Moreover the safety of irradiated food is acknowledged by major national and international food organizations and committees. The author agreed that when food irradiation has been approved by a country, consumers should be able to choose between irradiated and non-irradiated food. To enable the choice, clear and unambiguous labelling must be enforced. 13 refs., 1 tab., ills

    The energy used in food systems in the US amounts to about 16.5% of total US energy. An analysis has been made of the energy used in the many steps of the food-irradiation process. It is found that irradiation pasteurization uses only 21kJ/kg and radappertization 157kJ/kg, which is much less than the energy used in the other food processes. A comparison has also been made with other methods of preserving, distributing and preparing the meat for servings. It is found that the food irradiation can save significant amounts of energy. In the case of heat-sterilized and radiation-sterilized meats the largest fraction of the energy is used in the packaging, while in the frozen meats the largest energy consumption is by refrigeration in the distribution channels and in the home.

    With the increased consumption of processed food, quality control techniques are inevitably required in the food industry for its mass production and distribution. Recently, there has been a growing interest in the use of irradiation for solving the infrastructural problems in the food industry by developing viable alternatives to conventional technology and by improving the quality of processed foods. Even though food irradiation technology has been commercialized in 25 countries, and 18 items of irradiated foods have been approved for human consumption domestically, infrastructural studies are needed for the practical application of this technology. In order to enlarge the utilization of irradiation technology in solving the infrastructural problems of the food industry, this project was designed to investigate the efficacy of gamma irradiation for improving the process and physical properties of dried foods (corn and soybean), for preserving the reserved foods for emergency (red pepper) and for producing natural products (red polyketied pigment) using microbial immobilization with radiation-induced polymer

    The House of Commons was asked to support the Government's intention to allow the use of the irradiation of foodstuffs under conditions that will fully safeguard the interests of the consumer. The Government, it was stated, regards this process as a useful additional way to ensure food safety. The effect of the radiation in killing bacteria will enhance safety standards in poultry meat, in some shell-fish and in herbs and spices. The problem of informing the public when the food has been irradiated, especially as there is no test to detect the irradiation, was raised. The subject was debated for an hour and a half and is reported verbatim. The main point raised was over whether the method gave safer food as not all bacteria were killed in the process. The motion was carried. (U.K.)

    The number of products being radiation processed worldwide is constantly increasing and today includes such diverse items as medical disposables, fruits and vegetables, spices, meats, seafoods and waste products. This range of products to be processed has resulted in a wide range of irradiator designs and capital and operating cost requirements. This paper discusses the economics of low dose food irradiation applications and the effects of various parameters on unit processing costs. It provides a model for calculating specific unit processing costs by correlating known capital costs with annual operating costs and annual throughputs. It is intended to provide the reader with a general knowledge of how unit processing costs are derived. (author)

    Food irradiation is one of the most extensively and thoroughly studied methods of food preservation. Despite voluminous data on safety and wholesomeness of irradiated foods, food irradiation is still a “process in waiting.” Although some countries are allowing the use of irradiation technology on certain foods, its full potential is not recognized. Only 37 countries worldwide permit the use of this technology. If used to its full potential, food irradiation can save millions of human lives being lost annually due to food‐borne diseases or starvation and can add billions of dollars to the world economy. This paper briefly reviews the history and chemistry of food irradiation along with its main applications, impediments to its adoption, and its role in improving food availability and health situation, particularly in developing countries of the world

  16. Combination processes for food irradiation. Proceedings of the final research co-ordination meeting

    International Nuclear Information System (INIS)

    1998-01-01

    There is an increasing consumer demand for food that is safe, minimally processed, visually attractive, full flavoured, nutritious, and convenient to prepare and serve, that has fewer preservatives, and that is available throughout the year at an affordable cost. Consumer concern and regulatory restrictions on the use of preservatives and pesticides in food are adversely affecting international trade in many food products. As a result, minimally processed, chilled foods and ready to eat foods are increasingly being marketed to satisfy consumer demand in both developed and developing countries. However, such foods could introduce new microbiological risks to the population, especially to those who are immunocompromised or generally at risk (children, pregnant women, the elderly, etc.). In view of these factors, a 5 year Co-ordinated Research Programme (CRP) on Irradiation in Combination with Other Processes for Improving Food Quality was initiated in 1991 by the Food and Agriculture Organization of the United Nations and the International Atomic Energy Agency through their Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture. The objectives of this CRP were to evaluate: 1) Combination treatment involving irradiation in order to extend the self-life of meat, seafood, fruits and vegetables at refrigeration temperatures and under ambient conditions; 2) Combination treatment involving irradiation in order to ensure the microbiological safety of foods, both individual and composite, including prepared meals; 3) Shelf-life extension of chilled, prepared meals and the development of shelf stable food and food components through combination treatment involving irradiation; 4) Energy requirements of combination processes involving irradiation in comparison to other food processes. Scientists from 14 countries participated in the CRP by carrying out the work under Research Contracts and Agreements with the Joint FAO/IAEA Division. The first Research Co

    This international document highlights the major issues related to the acceptance of irradiated food by consumers, governmental and intergovernmental activities, the control of the process, and trade. The conference recognized that: Food irradiation has the potential to reduce the incidence of foodborne diseases. It can reduce post-harvest food losses and make available a larger quantity and a wider variety of foodstuffs for consumers. Regulatory control by competent authorities is a necessary prerequisite for introduction of the process. International trade in irradiated foods would be facilitated by harmonization of national procedures based on internationally recognized standards for the control of food irradiation. Acceptance of irradiated food by the consumer is a vital factor in the successful commercialization of the irradiation process, and information dissemination can contribute to this acceptance

    1988-01-01

    The nuclear industry has promoted food irradiation as an effective and safe means of preserving food at minimum risk to the public. However, wide-scale food irradiation programmes such as that approved in the United States of America would have an adverse impact on public health in the following ways: through the consumption of carcinogenic substances generated in irradiated foods, through the use of irradiation to mask bacteriological contamination of spoiled food, through the replacement of fresh foods with nutritionally depleted foods, through accidents with leaks or mishandling of the radiation sources used and through the environmental damage resulting from reactor operation or spent fuel reprocessing necessary to produce the required isotopes for food irradiation. The food irradiation market is potentially enormous, requiring a large number of facilities and isotopes, some, such as caesium-137, would come from the production of nuclear weapons. Evidence of the presence of carcinogenic or mutagenic activity in irradiated foods is discussed. Although the US Federal Drug Administration (FDA) has approved a food irradiation programme it would actually be against the FDA's legal obligation which is to protect the health and safety of the American people.

    The microbe-count reducing effects of gamma radiation and of ethylene oxide were compared in ground paprika and dried onion flakes. It was established that the commercially applied ethylene oxide gas treatment has the same bactericidal effect (2-3 log cycles reduction of the total viable bacterial count) as a 5kGy radiation dose. However, ethylene oxide treatment of paprika was practically ineffective in relation to the mould count, while irradiation with 5kGy destroyed the moulds very effectively. The colour and pigment content of paprika powder were not diminished by this radiation dose. A dry mixture intended for use in canned luncheon meat was treated with 5kGy. The canned meat product produced with the radiation-decontaminated ingredients was microbiologically stable even when heat-sterilized by a sterilization equivalent of F 0 =1.1. Considering the organoleptic features and microbiological safety, a heat treatment of about F 0 =3 is suggested when using irradiated ingredients. This is about the half of the F 0 value generally proposed for completely stable canned meat products. Besides the saving of energy, a good quality can be achieved by using radiation-decontaminated ingredients. (author)

    In this article the author presents the sanitary advantages that are brought by food irradiation. OMS experts state that this technique is safe and harmless for any average global dose between 10 KGy and 100 KGy. Whenever a seminar is held on the topic, it is always concluded that food irradiation should be promoted and favoured. In France food irradiation is authorized for some kinds of products and exceptionally above a 10 KGy dose. Historically food irradiation has been hampered in its development by its classification by American Authorities as food additives in 1958 (Delanay clause). The author draws a parallel between food irradiation and pasteurization or food deep-freezing in their beginnings. (A.C.)

  2. Food irradiation and sterilization

    Science.gov (United States)

    Josephson, Edward S.

    Radiation sterilization of food (radappertization) requires exposing food in sealed containers to ionizing radiation at absorbed doses high enough (25-70 kGy) to kill all organisms of food spoilage and public health significance. Radappertization is analogous to thermal canning is achieving shelf stability (long term storage without refrigeration). Except for dry products in which autolysis is negligible, the radappertization process also requires that the food be heated to an internal temperature of 70-80°C (bacon to 53°C) to inactivate autolytic enzymes which catalyze spoilage during storage without refrigeration. To minimize the occurence of irradiation induced off-flavors and odors, undesirable color changes, and textural and nutritional losses from exposure to the high doses required for radappertization, the foods are vacuum sealed and irradiated frozen (-40°C to -20°C). Radappertozed foods have the characteristic of fresh foods prepared for eating. Radappertization can substitute in whole or in part for some chemical food additives such as ethylene oxide and nitrites which are either toxic, carcinogenic, mutagenic, or teratogenic. After 27 years of testing for "wholesomeness" (safety for consumption) of radappertized foods, no confirmed evidence has been obtained of any adverse effecys of radappertization on the "wholesomeness" characteristics of these foods.

    Food irradiation is a physical method of processing food (e.g. freezing, canning). It has been thoroughly researched over the last four decades and is recognized as a safe and wholesome method. It has the potential both of disinfesting dried food to reduce storage losses and disinfesting fruits and vegetables to meet quarantine requirements for export trade. Low doses of irradiation inhibit spoilage losses due to sprouting of root and tuber crops. Food- borne diseases due to contamination by pathogenic microorganisms and parasites of meat, poultry, fish, fishery products and spices are on the increase. Irradiation of these solid foods can decontaminate them of pathogenic organisms and thus provide safe food to the consumer. Irradiation can successfully replace the fumigation treatment of cocoa beans and coffee beans and disinfest dried fish, dates, dried fruits, etc. One of the most important advantages of food irradiation processing is that it is a coldprocess which does not significantly alter physico-chemical characters of the treated product. It can be applied to food after its final packaging. Similar to other physical processes of food processing, (e.g. canning, freezing), irradiation is a capital intensive process. Thus, adequate product volume must be made available in order to maximize the use of the facility and minimize the unit cost of treatment. Lack of harmonization of regulations among the countries which have approved irradiated foods hampers the introduction of this technique for international trade. Action at the international level has to be taken in order to remedy this situation. One of the important limitations of food irradiation processing is its slow acceptance by consumers, due inter alia to a perceived association with radioactivity. The food industry tends to be reluctant to use the technology in view of uncertainties regarding consumer acceptance of treated foods. Several market testing and consumer acceptance studies have been carried

  5. The wholesomeness of irradiated food

    International Nuclear Information System (INIS)

    Elias, P.S.

    1976-01-01

    The acceptance of food irradiation as a safe process of preservation by national authorities concerned with the safety of foodstuffs has hitherto made slow progress. The technology has existed for some 25 years but the general attitude towards official acceptance of the process has been marred by irrational and unscientific fears. As may have been mentioned by previous speakers,'the basic process of food irradiation does not differ in the physical sense from any other food processing techniques which involve the application of radiation energy to food. The energy level used in food irradiation is too low ever to lead to any production of radioactivity in the irradiated food, hence wholesomeness considerations can totally exclude this aspect. The uniqueness of food irradiation rests inherently on the particular type of energy employed and has aroused special attention because of this fact. The wholesomeness of food treated by heat or microwaves has not been questioned to the same extent, yet the very same question has been raised in relation to treatment by gamma rays and electron beams. Being a new process it requires not only a toxicological but also a microbiological as well as nutritional approach to the assessment of the wholesomeness of irradiated food. Studies on the radiation chemistry of proteins, lipids and carbohydrates, the main constituents of foods, when irradiated in the Mrad range, have yielded information which shows that these substances react in a reasonably uniform manner to irradiation. Many of the irradiation-induced compounds identified in irradiated foods can also be found in various non-irradiated foods. For those products that have been identified, the quantities found are in the parts per million range or less. Available data on the structures of radiation chemical products in food and the very low concentrations at which they occur, suggest the general conclusion that the health hazard they might represent is negligible

    Food irradiation technology in South Africa is about to take its rightful place next to existing food preservation methods in protecting food supplies. This is as a result of several factors, the most important of which is the decision by the Department of Health and Population Development to introduce compulsory labelling of food irradiation. The factors influencing food irradiation technology in South Africa are discussed

    This presentation will focus on regulatory and administrative procedures recently developed to strengthen the control aspect of commercial use of food irradiation. Most of these developed by the International Consultative Group on Food Irradiation (ICGFI) established under the aegis of FAO, IAEA and WHO since 1984. ICGFI has produced a number of guidelines/codes of practice to assist national authorities in regulating the commercial use of food irradiation. The following regulatory control provisions will be highlighted: 1. Codes of good irradiation practice for specific application of food irradiation. 2. International inventory of authorised food irradiation facilities. 3. International training programmes for operators/plant managers of irradiation facilities and food inspectors. 4. International Dose Assurance Service (IDAS). 5. Labelling. 6. Certificate of irradiated food. (orig.) [de

    Food irradiation process has been studied and researched during 40 years, therefore it has been demonstrated its technical and economical feasibility, the advantages of this technology have been given to know to the consumers through educative campaigns. The marketing tests done in different countries mark the beginning of the trade because the consumers preferred irradiated food due to its quality and the increase of shelf life. This fact marks the incorporation of the irradiation techniques into the food industry. (Author)

  9. Food irradiation and the consumer

    Thomas, P.A.

    1990-01-01

    The poster presents a review of research work undertaken on the perception and understanding that consumers have of food irradiation. Food irradiation is not a revolutionary new food processing technique, in fact it is probably one of the most investigated methods presently available. Many countries such as Belgium, France, Denmark, Italy, Spain, the Netherlands and the United States of America permit food irradiation. In Britain it is presently banned although this is currently under review. Awareness of food irradiation by the general public in Britain, although not extensively researched would appear to be increasing, especially in the light of recent media coverage. New quantitative and qualitative work indicates that the general public are concerned about the safety and effectiveness of food irradiation. Research has shown that a large proportion of consumers in Britain, if given the opportunity to purchase irradiated food, would not do so. Further exploration into this response revealed the fact that consumers are confused over what food irradiation is. In addition, there is concern over the detection of irradiated food. The views presented in this paper, of the consumer reaction to irradiated food are of great importance to those involved in the food industry and industries allied to it, which are ultimately dependent on the consumer for their commercial survival.

    This article examines the cost competitiveness of the food irradiation process. An analysis of the principal factors--the product, physical plant, irradiation source, and financing--that impact on cost is made. Equations are developed and used to calculate the size of the source for planned product throughput, efficiency factors, power requirements, and operating costs of sources, radionuclides, and accelerators. Methods of financing and capital investment are discussed. A series of tables show cost breakdowns of sources, buildings, equipment, and essential support facilities for both a cobalt-60 and a 10-MeV electron accelerator facility. Additional tables present irradiation costs as functions of a number of parameters--power input, source size, dose, and hours of annual operation. The use of the numbers in the tables are explained by examples of calculations of the irradiation costs for disinfestation of grains and radicidation of feed

  14. Food irradiation receives international acceptance

    1982-04-01

    Irradiation has advantages as a method of preserving food, especially in the Third World. The author tabulates some examples of actual use of food irradiation with dates and tonnages, and tells the story of the gradual acceptance of food irradiation by the World Health Organization, other international bodies, and the U.S. Food and Drug Administration (USFDA). At present, the joint IAEA/FAO/WHO standard permits an energy level of up to 5 MeV for gamma rays, well above the 1.3 MeV energy level of /sup 60/Co. The USFDA permits irradiation of any food up to 10 krad, and minor constituents of a diet may be irradiated up to 5 Mrad. The final hurdle to be cleared, that of economic acceptance, depends on convincing the food processing industry that the process is technically and economically efficient.

  15. Recent developments in food irradiation

    Nowadays there is growing interest by the food industry, government and consumers in the use of food irradiatin to kill harmful insects, prevent diseases and keep food fresher longer. This interest has been stimulated by growing public concern over chemicals used in foods. While food irradiation technologies have been around for more than 50 years, only recently have they become cost effective and gained prominent attention as potentially safer ways of protecting food products and public health. This paper looks at recent developments in food irradiation processing and discusses the issues that lie ahead. (author)

    The effect of gamma-irradiation pretreatment on some mass transfer driven operations such as dehydration, osmotic dehydration and rehydration, commonly used in food processing, was studied. Applied irradiation up to 12.0 kGy resulted in decrease in hardness of the samples, as indicated by texture analysis. The effective diffusion coefficients of water and solute determined for dehydration, osmotic dehydration as well as for rehydration using a Fickian diffusion model. The effective diffusion coefficients for water (in case of osmotic dehydration and dehydration) and solid diffusion (in case of osmotic dehydration) were found to increase exponentially with doses of gamma-irradiation (G) according to an equation of the form D=A exp(-B/G), where A and B are constants. Microstructures of irradiated-carrot samples revealed that the exposure of carrot to gamma irradiation resulted in the breakage of cell wall structure, thereby causing softening of irradiated samples and facilitating mass transfer during dehydration and osmotic dehydration. The rehydration characteristics showed that gamma-irradiated sample did not absorb as much water as control, probably due to loss of cell integrity.

    2004-01-01

    Full text: A proper reaction mechanism was searched by analyzing the inactivation processes of microorganisms during food irradiation by ionizing radiation. By employing transition-state theory, it was assumed that the overall inactivation process involves a reversible sub-lethal stress and repair reactions to form reversibly injured cell or sensitized cell, which then undergoes irreversible injury leading to dead cell. A shoulder in low dose range in survival kinetics was associated with the repair process. Depending on the postulated mechanism, kinetic model equations were derived. The kinetics of cell inactivation by irradiation was expressed as depending on irradiation dose. By using experimental data in the developed model the inactivation parameters including threshold dose, radiation yield, decimal reduction dose and minimum sterilization dose were evaluated and microbial inactivation by irradiation was simulated by using the numerical values of the parameters. Developed model and model parameters may be used for the process control and the assessment of product quality in radiation preservation of food

    Malaysia recognised the potential of food irradiation as a technology that can contribute to solving some preservation problems associated with local agricultural produce. Research studies in this technology were initiated in late 1970s and since 1985, all activities pertaining to R and D applications, adoption and technology transfer of food irradiation were coordinated by The National Working Committee on Food Irradiation which comprises of members from research institutes, universities, regulatory agencies and consumer association. To date, technical feasibility studies conducted on 7 food items / agricultural commodities of economic importance demonstrated the efficacy of irradiation in extending shelf-life, improving hygienic quality and overcoming quarantine barriers in trade. Presently, 1 multipurpose Co-60 irradiator (I MCi), 2 gammacells and an electron beam machine (3 MeV) are available at MINT for research and commercial runs. The Malaysian Standards on Guidelines for Irradiation of Food was formulated in 1992 to facilitate application by local food industries. However, Malaysia has not yet commercially adopt the technology. Among many factors contributing to the situation is the apparent lack of interest by food industries and consumers. Consumer attitude study indicated majority of consumers are still unaware of the benefits of the technology and expressed concern for the safety of process and irradiated products due to limited knowledge and adverse publicity by established consumer groups. Although the food processors indicate positive attitude towards food irradiation, there remain many factors delaying its commercial application such as limited knowledge, cost-benefit, logistics and consumer acceptance. On the regulatory aspect, approval is required from the Director-General of Ministry of Health prior to application of irradiation on food and sale of irradiated food but efforts are being geared towards approving irradiation of certain food

    This practice describes dosimetric procedures to be followed in facility characterization, process qualification, and routine processing for electron beam and bremsstrahlung irradiation facilities for food processing to ensure that product receives an acceptable range of absorbed doses. Other procedures related to facility characterization, process qualification, and routine product processing that may influence and be used to monitor absorbed dose in the product are also discussed. Information about effective or regulatory dose limits for food products is not within the scope of this practice (see ASTM Guides F 1355 and F 1356). The electron energy range covered in this practice is from 0.3 MeV to 10 MeV. Such electrons can be generated in continuous or pulse modes. The maximum electron energy of bremsstrahlung facilities covered in this practice is 10 MeV. A photon beam can be generated by inserting a bremsstrahlung converter in the electron beam path (See ISO/ASTM Practice 51608

    The German official method L 06.00-37 (Para. 35 German Act on Food Irradiation) is used for the identification of irradiated fat-containing food by GC-analysis of radiation-induced hydrocarbons. Simple modifications in sample preparation allow a distinctive improvement in detection possibilities and detection limits as well. The applicability of the modified method for the detection of irradiated ingredients in model-like processed food is shown. An identification of only 3% (irradiated fat to total fat ratio) irradiated ingredient (1,5 kGy) in processed food was possible. Additionally, the kind of irradiated ingredient could be identified by the pattern of radiation induced hydrocarbons. Their concentrations are corresponding with the fatty acid composition of the irradiated compound. (orig.) [de

    Absorbed dose in a food product is determined and controlled by several components of the LINAC irradiation facility as well as the product. Standardization of the parameters characterizing the facility components, process load and the irradiation conditions collectively termed as 'process parameters' are of paramount importance for successful dose delivery to the food products. In the present study alanine-EPR dosimetry system was employed to optimize the process parameters of 10 MeV electron beam of a LINAC facility for commercial irradiation of food. Three sets of experiments were carried out with different food commodities namely, mango, potato and rawa with the available product conveying system of different irradiation geometry like one sided or both sided mode of irradiation. Three dimensional dose distributions into the process load for low dose requiring food commodities (0.25 to 1 kGy) were measured in each experiment. The actual depth dose profile in food product and useful scan width of the electron beam were found out to be satisfactory for commercial radiation processing of food. Finally a scaled up experiment with commercial food product (packets of Rawa) exhibited adequate dose uniformity ratio of 3 proving the feasibility of the facility for large scale radiation processing of food commodities.

    Twenty-five years of development work on the preservation of food by irradiation have shown that this technology has the potential to reduce post-harvest losses and to produce safe foods. The technological feasibility has been established but general acceptance of food irradiation by national regulatory bodies and consumers requires attention. The positive aspects of food preservation by irradiation include: the food keeps its freshness and its physical state, agents which cause spoilage (bacteria, etc.) are eliminated, recontamination does not take place, provided packaging materials are impermeable to bacteria and insects. It inhibits sprouting of root crops, kills insects and parasites, inactivates bacteria, spores and moulds, delays ripening of fruit, improves the technological properties of food. It makes foods biologically safe, allows the production of shelf-stable foods and is excellent for quarantine treatment, and generally improves food hygiene. The dose ranges needed for effective treatment are given

    Radiation processing of foods has been studied for over 30 years. To a considerable extent this research was carried out in the framework of various international projects. After optimistic beginnings in the 1950s and long delays, caused by uncertainty about the health safety of foods so treated, food irradiation has now reached the stage of practical application in several countries. In order to prepare the way for world-wide accceptance of the new process, the Codex Alimentarius Commission has accepted an 'International General Standard for Irradiated Foods' and an 'International Code of Practice for the Operation of Irradiation Facilities Used for the Treatment of Foods'. Psychological barriers to a process associated with the word 'radiation' are still formidable; it appears, however, that acceptance by authorities, food industry and consumers continues to grow

    Foods, e.g. chicken, shrimps, frog legs, spices, different dried vegetables, potatoes and fruits are legally irradiated in many countries and are probably also exported into countries, which do not permit irradiation of any food. Therefore all countries need analytical methods to determine whether food has been irradiated or not. Up to now, two physical (ESR-spectroscopy and thermoluminescence) and two chemical methods (o-tyrosine and volatile compounds) are available for routine analysis. Several results of the application of these four mentioned methods on different foods are presented and a short outlook on other methods (chemiluminescence, DNA-changes, biological assays, viscometric method and photostimulated luminescence) will be given.

    From the start the Netherlands has made an important contribution to the irradiation of food through microbiological and toxicological research as well as through the setting-up of a pilot plant by the government and through the practical application of 'Gammaster' on a commercial basis. The proceedings of this tenth anniversary symposium of 'Gammaster' present all aspects of food irradiation and will undoubtedly help to remove the many misunderstandings. They offer information and indicate to the potential user a method that can make an important contribution to the prevention of decay and spoilage of foodstuffs and to the exclusion of food-borne infections and food poisoning in man. The book includes 8 contributions and 4 panel discussions in the field of microbiology; technology; legal aspects; and consumer aspects of food irradiation. As an appendix, the report 'Wholesomeness of irradiated food' of a joint FAO/IAEA/WHO Expert Committee has been added. (orig./G.J.P.)

    Food irradiation principles; its main applications, advantages and limitations; wholesomeness, present activities at Ezeiza Atomic Centre; research coordinated by the International Atomic Energy Agency; capacity building; and some aspects on national and international regulations, standards and commercialization are briefly described. At present 56 countries authorize the consumption of varied irradiated foods; trade is performed in 32 countries, with about 200 irradiation facilities. Argentina pioneered nuclear energy knowledge and applications in Latin America, food irradiation included. A steady growth of food industrial volumes treated in two gamma facilities can be observed. Food industry and producers show interest towards new facilities construction. However, a 15 years standstill in incorporating new approvals in the Argentine Alimentary Code, in spite of consecutive request performed either by CNEA or some food industries restricts, a wider industrial implementation, which constitute a drawback to future regional commercialization in areas such as MERCOSUR, where Brazil since 2000 freely authorize food irradiation. Besides, important chances in international trade with developed countries will be missed, like the high fresh fruits and vegetables requirements United States has in counter-season, leading to convenient sale prices. The Argentine food irradiation facilities have been designed and built in the country. Argentina produces Cobalt-60. These capacities, unusual in the world and particularly in Latin America, should be protected and enhanced. Being the irradiation facilities scarce and concentrated nearby Buenos Aires city, the possibilities of commercial application and even research and development are strongly limited for most of the country regions.

  6. Food irradiation - Problems and promises

    Hickman, J.R.

    1974-01-01

    It has been stated that food irradiation represents the most significant discovery in food processing since Nicholas Appert invented canning in 1810. Certainly it is a process with great future potential; it is attractive because it works without heating the product, it is effective within sealed containers as well as for bulk usage, and it does not leave chemical residues on the treated food. Of course, no one process can be expected to solve all problems relating to preservation of food. Ionizing radiation can be used effectively to solve many of these problems, but the process is no panacea to cure the world's food problems. Unfortunately, early ill-founded claims about irradiation led to expectations which have proved beyond the reasonable capabilities of the process. Nevertheless, the number of foods that have been successfully treated, and the broad range of effects that can be achieved by radiation processing is impressive. (author)

    The need for forensic tests to identify irradiated foods has been widely recognised at a time of growing international trade in such products and impending changes in UK and EEC legislation to control the process. This paper outlines the requirements for and of such tests, and discusses recent developments in luminescence approaches aimed at meeting the needs of public analysts, retailers and consumers. Detecting whether or not food has been irradiated, and if so to what dose, is one of the challenges which food irradiation poses to the scientist. (author)

    The third phase of the Asian Regional Cooperative Project on Food Irradiation RPFI (Phase III) emphasized process control of pilot- and commercial scale irradiation of food according to the principle of the Codex General Standard for Irradiated Foods, and on gaining the acceptance of the process by governments, food industry and consumers. Phase III of the RPFI was funded by UNDP and was in operation from 1989-1993. Fifteen institutions in Australia, Bangladesh, China, India, Indonesia, Japan, the Republic of Korea, Pakistan, Philippines, Sri Lanka, Thailand and Viet Nam participated. Proper process control of irradiation with emphasis on dosimetry techniques was emphasized. A number of market testing, transportation trials and consumer acceptance studies was carried out during this period. Refs, figs, tabs.

  11. Food irradiation nears commercial development

    International Nuclear Information System (INIS)

    1981-01-01

    One person out of eight in the world today suffers from chronic undernourishment. This problem is likely to get worse as the world's population doubles during the next thirty to forty years. Since about 25% or more of our harvested food is lost due to various kinds of wastage and spoilage, food preservation is no less important than food production. To supply the world's demand for food, it is more reasonable to conserve what is produced than to produce more to compensate for subsequent losses. Thus, it is obvious that all methods of preserving food and agricultural produce should be examined to see if their use might alleviate the world's food shortage, and that to develop better and safer techniques of food preservation will improve food supplies. Food preservation is an ever greater problem for the developing countries, not only because of their chronic problems of undernourishment, but also because most of them are in tropical or sub-tropical regions where food spoilage is rapid. The IAEA and the Food and Agriculture Organization (FAO) held a symposium on food irradiation at Colombo in Sri Lanka. The symposium paid special attention to the use of food irradiation in preserving tropical fruits as well as fish and fish products. It also examined the cost of the food irradiation process and compared it with those of conventional processes. Food irradiation is one field in which advance is most likely to be achieved through international co-operation. This co-operation has been supported by the IAEA and FAO in a number of ways. During the last 15 years three previous symposia (Karlsruhe, 1966; Bombay, 1972; Wageningen, 1977), numerous panel meetings, and training courses, have been held on this subject and many nations' food irradiation projects have been supported by technical assistance and co-ordinated research programmes

    The authors' findings indicate that irradiation confers no advantage over heat processing in respect of bacterial toxins (clostridium botulinum, neurotoxin A and staphylococcal enterotoxin A). It follows that irradiation at doses less than the ACINF recommended upper limit of 10 kGy could not be used to improve the ambient temperature shelf life on non-acid foods. (author)

    IAEA was founded in 1957. 122 countries take part in it. It is operated with the yearly ordinary budget of about 20 billion yen and the technical cooperation budget of about 6 billion yen and by 2200 personnel. Its two important roles are the promotion of the peaceful utilization of atomic energy and the prevention of nuclear proliferation. The activities of IAEA are shown. The cooperation with developing countries and the international research cooperation program are the important activities. The securing of foods is an urgent subject, and the utilization of radiation and isotopes has been promoted, aiming at sustaining agriculture. The necessity of food irradiation is explained, and at present, commercial food irradiation is carried out in 28 countries including Japan. The irradiation less than 10 kGy does not cause poisonous effect in any food, according to JECFI. The new international agreement is expected to be useful for promoting the international trade of irradiated foods. The international cooperation for the spread of food irradiation and the public acceptance of food irradiation are reported. (K.I.)

    The basic research on food irradiation in Japan was begun around 1955 by universities and national laboratories. In 1967, food irradiation was designated to the specific general research on atomic energy, and the national project on large scale was continued until 1983. As the result, the treatment of germination prevention for potatoes was approved by the Ministry of Health and Welfare in 1972. The Co-60 gamma ray irradiation facility of Shihoro Agricultural Cooperative is famous as the facility that succeeded in the practical use of food irradiation for the first time in the world. But the practical use of food irradiation stagnates and the research activities were reduced in Japan due to the circumstances thereafter. The effect of radiation to foods and living things is explained. The features of the radiation treatment of foods are small temperature rise, large transmissivity, no residue, the small loss of nutrition and large quantity, continuous treatment. The safety of irradiated foods is explained. The subjects for hereafter are discussed. (K.I.)

    This Ghana Standard specifies the requirements and methods of sampling and testing for foods processed by irradiation for sprout inhibition, insect disinfestation, microbial decontamination, delaying ripening, shelf-life extension and general phytosanitary treatment. The absorbed dose range covered by this guide is between 0.2kGy and 10kGy. The practical minimum or maximum dose of a treatment may be lower or higher than this range, depending on the purpose of irradiation and the radiation tolerance of the particular type of food. This standard does not apply to foods exposed to radiation imparted by measuring instruments used for inspection purposes

    Irradiation of food has been promoted as a new technology in the preservation of food. Several countries have already introduced the technology for selected food items. However, there remain several questions that have yet to be answered. Foremost is the question of its safety. Proponents have argued that it is safe. Others cast doubts on these studies and the interpretations of their results. Second is the question of the nutritive value of the food that is irradiated. These and many other questions related to safety will be discussed in this paper

    Morrison, R.M.

    1986-01-01

    The first experimental studies on the use of ionizing radiation for the preservation of foods were published over thirty years ago (1, 2) . After a period of high expectations and perhaps exaggerated optimism a series of disappointments occurred in the late '60s .The first company specifically created to operate a food irradiation plant, Newfield Products Inc, ran into financial difficulties and had to close its potato irradiation facility in 1966. The irradiator, designed to process 15,000t of potatoes per month for inhibition of sprouting, was in operation during one season only. In 1968 the US Food an Drug Administration refused approval for radiation-sterilisation of ham and withdrew the approval it had granted in 1963 for irradiated bacon. An International Project on the Irradiation of Fruit and Fruit juices, created in 1965 at Seibersdorf, Austria, with the collaboration or 9 countries, ended with general disappointment after three years. The first commercial grain irradiator, built in the Turkish harbour town of Iskenderun by the International Atomic Energy Agency with funds from the United Nations Development Program, never received the necessary operating licence from the Turkish Government and had to be dismantled in 1968. The US Atomic Energy Commission terminated its financial support to all research programmes on food irradiation in 1970. For a number of years, little chance seemed to remain that the new process would ever be practically used. However, research and development work was continued in a number of laboratories all over the world, and it appears that the temporary setbacks now have been overcome. Growing quantities of irradiated foods are being marketed in several countries and indications are that irradiated foods will eventually be as generally accepted as are frozen, dried or heatsterilised foods

    Hartmann, M.; Ammon, J.; Berg, H.

    1997-01-01

    Detection of irradiated components in processed food with complex lipid matrices can be affected by two problems. First, the processed food may contain only a small amount of the irradiated component, and the radiation-induced hydrocarbons may be diluted throughout the lipid matrix of the whole food. Second, in complex lipid matrices, the detection of prior irradiation is often disturbed by fat-associated compounds. In these cases, common solid phase extraction (SPE) Florisil clean-up alone is inadequate in the detection of prior irradiation. Subsequent SPE argentation chromatography of the Florisil eluate allows the measurement of small amounts of irradiated lipid-containing ingredients in processed food as well as the detection of prior irradiation in complex lipid matrices such as paprika and chilli. SPE argetation chromatography is the first method available for the selective enrichment of radiation-specific hydrocarbons from even complex lipid matrices, thus enabling the detection of irradiation does as low as 0.025 kGy. Furthermore, by using radiation-induced hydrocarbons in the detection of prior irradiation of paprika and chilli powder, a second independent method, the first being measurement of thermoluminescence, is available for the analysis of these matrices. Such analysis could be achieved by using this highly sensitive, cheap and easy to perform combined SPE Florisil/argentation chromatography method, without the need for sophisticated techniques like SFE-GC/MS or LC-GC/MS, so that highly sensitive detection of prior irradiation colud be performed in almost every laboratory

    1985-01-01

    The aim of food irradiation is to extend shelf-life of food commodities by delaying fruit ripening, inhibition of vegetable sprouting, desinfestation of grains and seeds, and in general by controlling microbial or parasitic food-transmitted infections. It was stated by the 1980 Joint FAO/IAEA/WHO Expert Committee that food irradiated up to 10 kGy does not pose any human health or nutritional problems. Following this recommendation, irradiation programmes are being developed at a good pace in several countries. It is hoped that commercial drawbacks now existing, such as psychological apprehension of consumers to radiation-treated products and innovative inertia to changes of the food chain, will be removed through appropriate information schemes and legislative advancement.

    Food preservation by means of ionizing radiation has been technically feasible for more than a decade. Its utilization could increase food safety, extend the transport and shell life of foods, cut food losses, and reduce dependence upon chemical additives. The prime obstacles have been the strict safety requirements set by health authorities to this preservation method and the high costs of the long-term animal tests necessary to fulfil these requirements. An International Food Irradiation Project, expected to establish the toxicological safety of 10 foods by about 1976, is described in some detail. (author)

    Food irradiation has recently been visited as a technology that can contribute to the solution of problems associated with food preservation of Malaysia's agriculture produce and products thereby improving the economic status of the rural sector. However, the history of food irradiation in Malaysia is very recent. Research carried out on food irradiation only began in 1974 as a result of the installation of a 60 Co facility (initially 10,000 Ci) at the National University of Malaysia. Since its installation several studies have been carried out pertaining to the food irradiation. Presently its development has been slow. Research in this area has been confined to laboratory scale and purely academic. This limitation is due to a number of reasons, among others are: a) limited number of facilities; b) lack of expertise to conduct its research; c) other preservation methods can be improved with lower capital output. An important step towards its development was made when Malaysia actively participated in the RCA/IAEA food irradiation project, viz. the irradiation of pepper which was carried out at the National University of Malaysia in the 80's. As a result of this venture, research and development activities in food irradiation have been geared toward semi-plot scale with the view ot commercialization in the future. In 1982, a group of researchers was formed to conduct feasibility studies using irradiation techniques in trying to overcome several problems associated with our local paddy and rice. Another group is being organized by the National University of Malaysia to look into the problems associated with the preservation of frozen shrimps. (author)

    The Chinese officials outlined China's past and future directions at a recent international food irradiation seminar in Shanghai sponsored by the FAO and IAEA. The meeting was attended by about 170 participants from China and 22 other countries, primarily from the Asian and Pacific region. Three food irradiation plants currently are operating in the region and 14 more are planned over the next 5 years. It was reported that China continues to suffer high food losses, up to 30% for some commodities, primarily due to preservation and storage problems. In January 1986, the first of five regional irradiation facilities planned in China officially opened in Shanghai. The Shanghai irradiation centre plans to process up to 35,000 tons of vegetables a year, as well as some spices, fruits, and non-food products. The Ministry of Public Health has approved seven irradiated foods as safe human diets: rice, potatoes, onions, garlic, peanuts, mushrooms and pork sausages; approval for apples is expected shortly. The Chinese officials at the Shanghai meeting stressed their openness to foreign participation and cooperation in food irradiation's development

    The Canadian government are discussing the legislation, regulations and practical protocol necessary for the commercialization of food irradiation. Food industry marketing, public relations and media expertise will be needed to successfully introduce this new processing choice to retailers and consumers. Consumer research to date including consumer opinion studies and market trials conducted in the Netherlands, United States, South Africa and Canada will be explored for signposts to successful approaches to the introduction of irradiated foods to retailers and consumers. Research has indicated that the terms used to describe irradiation and information designed to reduce consumer fears will be important marketing tools. Marketers will be challenged to promote old foods, which look the same to consumers, in a new light. Simple like or dislike or intention to buy surveys will not be effective tools. Consumer fears must be identified and effectively handled to support a receptive climate for irradiated food products. A cooperative government, industry, health professional, consumer association and retailer effort will be necessary for the successful introduction of irradiated foods into the marketplace. Grocery Products Manufacturers of Canada is a national trade association of more than 150 major companies engaged in the manufacture of food, non-alcoholic beverages and array of other national-brand consumer items sold through retail outlets

    Trade in food and agricultural products is important to all countries, the economies of many developing countries would be significantly improved if they were able to export more food and agricultural products. Unfortunately, many products can not be traded because they are infested with, or hosts to, harmful pests, contaminated with microorganisms, or spoil quickly. Foods contaminated with microorganisms cause economic losses, widespread illness and death. Several technologies and products have been developed to resolve problems in trading food and to improve food safety, but none can provide all the solutions. Irradiation is an effective technology to resolve technical problems in trade of many food and agricultural products, either as a stand- alone technology or in combination with others. As a disinfestation treatment it allows different levels of quarantine security to be targeted and it is one of few methods to control internal pests. The ability of irradiation virtually to eliminate key pathogenic organisms from meat, poultry, and spices is an important public health advantage. In addition to controlling pests and eliminating harmful bacteria, irradiation also extends the storage life of many foods. In the laboratories of Turkish Atomic Energy Authority, many research projects were completed on the effects of gamma irradiation to the storage life of chicken meat, anchovy, Turkish fermented sausage, dried and fresh fruits and vegetables and also research projects were conducted on the effects of gamma irradiation on microorganisms (Salmonella, Campylo-bacteria, E.coli and S.aureus in white and red meat) and parasites (food-borne, trichostrongylus spp. and Nematodes spp.)

    For the exact understanding on food irradiation in Japan, it is important to provide information of food irradiation to consumers, industries and government offices. However, many of information on food irradiation are only restricted in a few experts or institutes relating to this field. For this reason, data base of food irradiation has been completed together with the systems necessary for input the data using computer. In this data base, about 630 data with full reports were inputted in computer in the field of wholesomeness studies, irradiation effects on food, radiation engineering, detection methods of irradiated food and Q and A of food irradiation for easy understanding. Many of these data are inputted by Japanese language. Some English reports on wholesomeness studies are also included which were mainly obtained from international projects of food irradiation. Many of data on food irradiation are responsible in the fields of food science, dietetics, microbiology, radiation biology, molecular biology, medical science, agricultural science, radiation chemistry, radiation engineering and so on. Data base of food irradiation contains many useful data which can apply to many other fields of radiation processing not only on food irradiation but also on sterilization of medical equipments, upgrading of agricultural wastes and others.

    A new kind of label dosimeters based on the polyvinyl butyral and dye compounds including leuco malachite green and methyl orange was developed for use as devices for discriminating and monitoring radiation treatment in food irradiation. The dosimeters change their color from orange-yellow to greenish under irradiation with gamma rays or electrons to dose just about 3 kGy. The greenish continue to develop to deep-green upon the increase of dose to 10 kGy. This makes the indicators useful for the dose range of food irradiation application, especially in treatment of frozen meat and sea products for elimination of micro-organism. The indicators were made in a stick-on label type showing attractive characteristics in use. The orange-yellow color before irradiation keep well stable under normal conditions in laboratory. The green after irradiation maintained as long as 6 months in practical conditions of products. New indicators can fill the gap in the demand of labeling indicators of food irradiation in our country as well as the world. (author)

    This paper deals with a solid phase extraction (SPE) method for the isolation of irradiation induced hydrocarbons which can replace the column chromatography described in the paragraph 35 LMBG (German Food Law) procedure L06.00-37. Using this new method, only a tenth of solvents and column material is necessary. The SPE method was a good as LC-LC-GC/FID or LC-LC-GC/MS in analyzing new or complex matrices like paprika or salmon. Additionally, it is fast, cheap and easy to perform. As far as we know, the detection of irradiation traetment in paprika powder by analyzing irradiation induced hydrocarbons has not been described before. The new method is a good alternative for the commonly used thermoluminescence procedure. (orig.) [de

    Food irradiation is to contribute to the stable security of foodstuffs which is the fundamental condition of human survival by improving the preservation of foodstuffs and food sanitation utilizing the biological effect due to irradiation. The research and development have been carried out internationally since 1950s, but after the safety declaration of irradiated foods in 1980 by the international organ concerned, the permission and practical use for foods in various foreign countries, the technology transfer to developing countries and so on have been advanced. At present, food irradiation is permitted in 38 countries, and the practical irradiation is carried out in 24 countries. In Japan, the irradiation of potatoes to prevent germination was permitted in 1972, and the practical irradiation on potatoes of yearly 15,000 t is carried out. In the near future, irradiated foods will appear in international foodstuff market, and Japan which imports foodstuffs must cope with them. Foodstuffs and the safety, food irradiation, the soundness of irradiated foods, food irradiation in various foreign countries and Japan, the trend of international organs and the criticism of food irradiation are reported.

    Food Technology Division, Bhabha Atomic Research Centre, Mumbai has demonstrated that radiation processing of foods can contribute to nations food security by reducing post-harvest losses caused by insect infestation, microbial-spoilage and physiological changes. The technology has commercial potential for the conservation of cereals, pulses and their products, spices, onions, potatoes, garlic, some tropical fruits, sea foods, meat and poultry. Irradiation can ensure hygienic quality in foods including frozen foods by eliminating food borne pathogens and parasitic organisms. It offers a viable environment friendly alternative to chemical fumigants for quarantine treatment against insect pests in agricultural and horticultural products entering international trade. The safety and nutritional adequacy of irradiated foods for human consumption is well established. About 40 countries including India have regulations permitting irradiation of foods and 28 countries are irradiating foods for processing industries and institutional catering

    This report describes developments and applications of the thermoluminescence (TL) analysis of mineral contaminants in foods. Procedures are presented to obtain minerals from most different products such as pepper, mangos, shrimps and mussels. The effect of light exposure during the storage of foods on the TL intensity of minerals is examined and corresponding conclusions for routine control are drawn. It is also shown that the normalization of TL intensities - the essential step to identify irradiated samples - can not only be achieved by γ, X or β rays but also by UV radiation. The results allow the conclusion that a clear identification of any food which has been irradiated with more than 1 kGy is possible if enough minerals can be isolated. (orig.)

    A survey was conducted on Malaysian food industries to determine the interest and potential applications of food irradiation as an alternative or to complement existing food preservation treatments. A total of 37 food processors representing 5 subsectors of the food industry participated in the survey. Information collected showed that majority of respondents were aware of food irradiation but the level of knowledge was low. Half of respondents perceived food irradiation as safe and 23% will consider using it for commercial purposes. Main concerns of the food processors were safety of the process, safety of irradiated food, efficacy of the process and consumer acceptance. Food irradiation applications considered to have the most potential for use by the food industry, were those which would improve the hygienic quality of food products. Despite the limited knowledge, respondents strongly supported the need to promote food irradiation technology in Malaysia. In view of this finding. various promotional activities have been continuously carried out to increase public awareness and understanding of the technology so as to facilitate acceptance of food irradiation in Malaysia.

    For some years research has been done in several countries, with the object of contributing to the world's food supplies, on the application of nuclear methods to food preservation and processing. The importance of food preservation is of particular relevance in certain regions of the world where up to thirty per cent of harvested foodstuffs are being lost because of damage by animal pests and microorganisms. A series of international meetings have been held on this subject; the first, held in 1958 at Harwell, was followed by further meetings in 1960 in Paris and in 1961 in Brussels. The International Symposium on Food Irradiation organized by the International Atomic Energy Agency and the Food and Agriculture Organization of the United Nations through their Joint Division of Atomic Energy in Agriculture, and held at the Karlsruhe Nuclear Research Centre, Karlsruhe, from 6 to 10 June 1966, at the generous invitation of the Government of the Federal Republic of Germany, is the most recent of this series of meetings. It was held for the purpose of exchanging the most up-to-date results of research, of contributing towards co-operative efforts between Member States, and of stimulating trade in the international exchange of irradiated products between nations. Papers describing research over the past fourteen years were given by outstanding authorities; the results point to a breakthrough having been achieved in the use of ionizing radiation in food preservation, notwithstanding some problems still to be solved, such as overcoming changes in colour, flavour, odour or texture. The Symposium was attended by over 200 scientists from 25 countries and four international organizations. Sixty-nine papers were presented. It was shown that a wide variety of foodstuffs exist for which radiation could be used for three different purposes: to produce indefinitely stable products, to rid food of organisms that constitute health hazards, and to extend the normal shelf or market life

    A mail survey technique was used to determine if value hierarchy, locus of control, innovativeness, and demographic parameters could distinguish between subjects expressing different levels of concern and willingness to buy irradiated food. Concern toward irradiated food was lower than concern for other food safety issues, probably because many expressed uncertainty regarding irradiation. Those ranking the value “an ecologically balanced world” expressed the greatest irradiation concern. Factors which could predict high irradiation concern were being highly concerned about the use of chemical sprays on food, completing more formal education and being female; those believing that life was controlled by luck were less concerned. Irradiation concern was a principal factor determining willingness to buy irradiated foods. Innovative consumers were more likely to try irradiated foods than noninnovative. Implications for consumer education are presented

    Food irradiation, a controversial technology, has captured the interest of government, industry and consumers in recent years. Consumers need to learn what irradiation is, why it is used to process foods, what the government thinks about it, what foods are being irradiated, and what its chances are for successful commercialization. That information will better enable them to make informed decisions about irradiated foods

    Effects of combined heating and gamma radiation on Clostridium sporogenes spores and Salmonella seftenberg were examined. The order in which irradiation and heat were applied had a profound effect on the survival of the organisms. Heating of C.sporogenes spores at 95 degrees Celsius had very little effect on their sensitivity to subsequent irradiation, but irradiation of the spores at 0 degrees Celsius increased their sensitivity to subsequent heat treatment and thus reduced their heat D 10 values (time required to activate the spores to 10% of their initial number). This radiation-induced heat sensitivity increased with the increase in radiation dose. The Z values (change in temperature required for a tenfold change in D 10 values) of the spores were found to increase with the increase in pre-irradiation dose. Radiation-induced heat sensitivity was found to persist for at least 35 days in spores irradiated in frozen or freeze-dried states in distilled water or in phosphate buffer suspensions, and for at least 14 days in a number of food slurries. In phosphate buffer and nutrient broth suspensions, the radiation-heat synergism decreased with increasing pH of the media from pH 4.7 to pH 7.5. However, the effect of pH on synergism was less pronounced in spores suspended in some food slurries. Preliminary results indicate that pre-irradiation of S. senftenberg at 0.5 kGy did not change the heat sensitivity of this organism at 52 degrees Celsius, but when radiation and heat were applied simultaneously, synergistic inactivation was observed even at 50 degrees Celsius. Practical implications of these results are discussed

From the sixties food irradiation has been applied more and more, so that the consumer movement has become alert to this technology. Since then a lot of controversies have arisen in the literature about wholesomeness, safety, effects, etc. Food irradiation is currently permitted on a small scale in about 30 countries; in some countries or states food irradiation has been put under a ban (e.g. Australia, New Zealand, New Jersey). The World Health Organization (WHO) and the Food and Agriculture Organization of the United Nations (FAO) have, however, chosen food irradiation as a safe and sound method for preserving and improving the safety of food. Reactions on the part of the consumer organizations of many countries are however not in favour of or are even opposed to food irradiation. In this chapter consumer acceptance related to technological developments is described, then the convergence of the consumer movement on public opinion and concern on food irradiation is discussed. The need for labelling of irradiated food products is discussed and finally recommendations are given of ways to change consumers attitudes to food irradiation. (author)

    Recent positive developments in regulatory matters involving food irradiation appear to be opening the door to commercial implementation of the technology. Experience gained over five years in operating multi-purpose food irradiation facilities in the United States have demonstrated the technical and economic feasibility of the radiation preservation of food for a wide variety of purposes. Public education regarding food irradiation has been intensified especially with the growing favorable involvement of food trade associations, the USDA, and the American Medical Association. After 41 years of development effort, food irradiation will become a commercial reality in 1985. (author)

  13. Ways in which irradiation could improve the effectiveness of several existing food preservation processes in South Africa

    1982-01-01

    With the introduction of irradiation as a possible food preservation method nearly three decades ago, there was a tendency to over-emphasise the advantages to be gained with this new process to the extent that some regarded this new technique as a panacea for most of the problems experienced in the preservation of food at that time. The pendulum swung to the other extreme when irradiation did not come up to the expectations associated with a so-called 'wonder' treatment and others took a decidedly pessimistic attitude towards the future of this process. The answer obviously lies between these two extreme views and fortunately this is the attitude prevailing in many countries towards irradiation treatment at the present time. The role of irradiation can be seen as supplementary and indeed complementary to existing preservation methods instead of being regarded as directly competitive. In this paper, several preservation processes will be considered such as heat treatment, canning and refrigeration, and the effectiveness of these methods in combination with irradiation treatment will be considered with respect to shelf-life extension of several important fruits and vegetables in South Africa. The possible mechanism of the combined or synergistic effect in relation to disease control in selected biological systems will also be discussed

    Irradiation is a technology which has been exploited in a wide variety of industries ranging from sterilization of medical products and polymer modification to applications with respect to food. Whilst food irradiation has recently become a controversial subject, the process has been studied for many years. Many products could be irradiated to advantage and these need to be thoroughly investigated before final recommendations can be made as to the commercial feasibility and suitability of the processing technology in the Northern Ireland context

    Dutch research showed great interest in the potential of food irradiation at an early stage. The positive research results and the potential applications for industry encouraged the Ministry of Agriculture and Fisheries to construct a Pilot Plant for Food Irradiation. In 1967 the Pilot Plant for Food Irradiation in Wageningen came into operation. The objectives of the plant were: research into applications of irradiation technology in the food industry and agricultural industry; testing irradiated products and test marketing; information transfer to the public.

    The commercial use of irradiated food technology in Brazil has a slow growing due to misinterpretation by most Brazilian consumers, who have been mislead by wrong ideas about the meaning of what is nuclear energy. Researches indicate that consumers have difficult in accepting such a technology due to the confusion between the terms irradiation and radioactivity, which are often related to health risks. When properly informed about the process, its purpose and the benefits offered by food irradiation technology, most consumers react positively. Therefore, this work aims to: first, to evaluate the acceptance of irradiated foods by Brazilian consumers; second, to verify the teaching at school about the food irradiation process; third, to analyze the Brazilian school curriculum from elementary school to high school, regarding nuclear energy applications; then, to compare the content taught in Brazil with the content covered in other surveyed countries, such as France, United States, and China. The methodology of this study consisted of a systematic survey of the specific literature, and a questionnaire to verify the acceptance of irradiated food by Brazilian consumers. According to the researched bibliography, it was clear the recommendation of an early school education about the usage of nuclear energy, more specifically, food irradiation. Such a recommendation is due to the fact that the consulted costumers, in Brazil and other countries mentioned in this work, do not clearly understand the full benefits of irradiated food. Hence, education is fundamental for the acceptance of new technologies by consumers, as it is the case with irradiated food. (author)

    Anticipating that food irradiation may soon become an important addition to the many food processing techniques currently available, this article discusses many aspects of this process. Primarily, the benefits of irradiation for all foods include insect and bacterial control, increasing the potential to reduce incidences of food-borne illnesses, in addition to delaying the deterioration of fruits and vegetables. Currently approved uses of food irradiation in the U.S. and other countries, a summary of the proposed rule for wider application, and the labeling issue encompassed in the proposal are addressed. Additionally, the areas of great consumer concern--safety and public health implications, are talked about with the conclusion that food irradiation has been declared safe

    Many fields such as industry, agriculture, medical treatment and environment use radiation. This report explained some examples of irradiation applications. Radiation source is {sup 60}Co {gamma}-ray. Polymer industry use radiation for radiation curing (thermally stable polymer), tire, expanded polymer, radiation induced graft copolymerization and electron beam curing. On environmental conservation, radiation is used for elimination of NOx and SOx in exhaust combustion gas. In the medical treatment, radiation is applied to sterilization of medical instruments, that occupied about 50% volume, and blood for transfusion, which is only one method to prevent GVHD after transfusion. On agriculture, irradiation to spice, dry vegetable, frozen kitchen, potato and garlic are carried out in 30 countries. However, potato is only a kind food in Japan. Radiation breeding and pest control are put in practice. (S.Y.)

    Full-text: India recently celebrated 50 years of nuclear application and criticality. Radiation processing Technology has been investigated and demonstrated for nearly four decades by food scientists and technologists at Bhabha Atomic Research Center, (BARC), India. It is quite essential to clarify unambiguously that under no circumstances can radiation processing using cobalt-60 radiation induce any radioactivity and naturally, leave residual radioactivity in the material being processed. To this extent, the word IRRADIATION has been replaced by the word Radiation Processing. The Indian Navy had recently approved the use of radiation processing for preserving high value food products and to optimize the procurement cost and maximize the product availability. The Board of Radiation and Isotope Technology (BRIT), India has achieved significant milestones in encouraging private entrepreneurs to set up Radiation Processing plants for food preservation and safety as well as for non-food products and medical equipment sterilization. Today there are about 25 private radiation processing plants getting ready to meet the demand and many more are following the trend. With the growing demand for Cobalt-60 source, India has exported the technology and the source to many neighboring countries and is prepared to meet the demand and support the requirements of the Cobalt-60 source in Thailand. Innovative Food Technologies Co. Ltd provide consultancy and turnkey projects to set up Radiation processing Plants, Supply of Cobalt-60 source, Refurbishing Cobalt-60 source, provide comprehensive training in Plant safety, maintenance and security in Thailand and ASEAN

    A US survey assessed the extent of attitude change toward food irradiation when consumers were given the opportunity to read about and discuss food irradiation. Consumers showed a higher level of concern for preservatives and chemical sprays than for the use of food irradiation for ensuring food safety. The study further revealed that consumer attitudes toward food irradiation can be positively influenced by an educational effort, and that this influence is most effective when the consumer can interact with someone knowledgeable about food irradiation. Willingness to buy irradiated foods was based on the safety of the process rather than on the advantages of any specific food product

    Over 3 decades of research and developmental effort in India have established the commercial potential for food irradiation to reduce post-harvest losses and to ensure food safety. Current regulations permit irradiation of onions, potatoes and spices for domestic consumption and operation of commercial irradiators for treatment of food. In May 1997 draft rules have been notified permitting irradiation of several additional food items including rice, wheat products, dry fruits, mango, meat and poultry. Consumers and food industry have shown a positive attitude to irradiated foods. A prototype commercial irradiator for spices set up by Board of Radiation and Isotope Technology (BRIT) is scheduled to commence operation in early 1998. A commercial demonstration plant for treatment of onions is expected to be operational in the next 2 years in Lasalgaon, Nashik district. (author)

    It has been suggested that the minor losses of nutrients associated with radiation processing may be further reduced by irradiating foods at the high dose rates generally associated with electron beams from accelerators, rather than at the low dose rates typical of gamma irradiation (e.g. 60 Co). This review briefly examines available comparative data on gamma and electron irradiation of foods to evaluate these suggestions. (137 refs., 27 tabs., 11 figs.)

    The detection of irradiated constituents in processed food with a complex lipid matrix can be adversely affected by two conditions. The small amounts of radiation-induced hydrocarbons are diluted by the fat matrix of the food, or there are substances accompanying the lipids in the matrix and thus make the analysis more difficult. In those cases, sample preparation alone by means of Florisil SPE (solid-phase extraction) is not enough and requires additional, subsequent SPE argentation chromatography of the Florisil eluate, as this latter analytical method permits reliable detection down to very small amounts of irradiated, fat-containing constituents even in a complex lipid matrix. SPE-Florisil/argentation chromatography detects and selects radiation-induced hydrocarbons in a complex lipid matrix, so that detection of irradiation at even very low doses down to 0.025 kGy is possible. The method described is highly sensitive, inexpensive, and easy to apply. It efficiently substitutes such complex preparation or measuring methods as SFE-GC/MS or LC-GC/MS. This highly sensitive testing method for detection of food irradiation can be carried out in almost any analytical laboratory. (orig./CB) [de

  11. Is irradiation of food stuffs safe?

    2014-01-01

    Many advanced and several developing countries have abundant supplies of fresh, safe and nutritious food stuffs. Yet, despite the many precautions and processes in place to ensure safe food supply, microbial contamination is still a concern. There are a number of food processing tools available that provide additional protection for the food we consume. One very promising tool is food irradiation, which is a process of imparting ionizing energy to food to kill microorganisms. Food irradiation is the process of exposing food to a controlled source of ionising radiation for the purposes of reduction of microbial Ioad, destruction of pathogens, extension of product shelf life, and/or disinfection of produce. The term irradiation often evokes fears of nuclear radioactivity and cancer among consumers. The process seems frightening because it is powerful and invisible. Consequently questions and concerns exist particularly about the safety or wholesomeness of irradiated food. The paper highlights food irradiation as a food safety measure and the issues of concerns for consumers. (author)

    Doellstaedt, R.; Huebner, G.

    After the acceptance of food irradiation up to an overall average dose of 10 kGy recommended by the Joint FAO/IAEA/WHO Expert Committee on the Wholesomeness of Irradiated Food in October 1980, the G.D.R. started a programme for the development of techniques for food irradiation. A special onion irradiator was designed and built as a pilot plant for studying technological and economic parameters of the irradiation of onions. The new principle of bulk-cargo irradiation allows the integration of this technology into the usual harvest technology for onions on the way from field to storage. Scientific and applied research work has been carried out in the past 3 yr on the irradiation of spices, potatoes, eviscerated chicken, animal feeds, fodder yeast, drugs and vaccines. In connection with the irradiation of eviscerated chicken, fodder yeast and animal feeds the basis of an antisalmonella programme has been discussed. Germ-count-reduced spices were employed for the production of test charges of preserves and tinned products. The results have led to the decision to design and build a new multipurpose irradiator for food irradiation. In order to cover the legal aspects of food irradiation the Ministry of Health issued regulations concerning the recommendation of irradiated food in the G.D.R.

    Living frogs and their internal organs are highly contaminated with several serotypes of Salmonella. The high level of contamination was carried along with frog legs upon arrival at processing plants. Washing in chlorinated water and freezing reduced but did not eliminate Salmonella from the product. Irradiating frog legs artificially contaminated with Salmonella up to 10 6 /g before freezing showed that a dose of 3 kGy and above resulted in no detection of the bacteria. If irradiation was carried out after freezing, a dose of 4 kGy and above has to be used. The latter procedure appears to be more feasible commercially than the former one. It was concluded that a combination of chlorination, freezing and irradiation with a dose ranging from 3 to 6 kGy should provide sufficient conditions for elimination of Salmonella in the product. The treatment also results in lowering the total viable count to less than 500,000 cells/g to conform with the standard requirements for export

    With respect to the safety of irradiated food, the Korean government has accepted in principle the recommendations of international organization (FAO, WHO, IAEA, CAC, etc) as well as the national-based evaluations. Gamma radiation from Co-60 is now authorized to be used for food irradiation of 26 food items (or classes). Two multipurpose gamma-irradiation facilities (Greenpia Tech. Inc. since 1987; SOYA Co. Ltd. since 2002) are now operating for the treatments of selected food items as well as medical supplies. At present, labeled-irradiated products are not yet being marketed at the consumer level. As an alternative process of chemical fumigants, however, irradiation is being partially utilized for the microbial decontamination and pest control of dried spices, vegetable ingredients, etc. for their use in processed foods as minor ingredients. Commercial applications of food irradiation, though small in number, have been steady ever since. This article introduces the commercial progress in food irradiation technology in Korea in terms of research activities, legislation, commercialization, and the control of irradiated foods. (author)

    The UK Government has decided to lift the ban on food irradiation. The proponents of food irradiation claim it is an effective and safe means of preserving food, at minimum risk to the public. However, the prospect of irradiated food being on the shelves has created considerable opposition from environmental, consumer, public health groups and trade unions. The long list of unanswered health and safety questions means the public could be exposed to a whole new range of risks. The consumer is justified as saying ''if food has to be irradiated, what was wrong with it, good food does not need irradiating''. The answer to food contamination is improved hygiene and training in farm, factory and shop. (author)

    Food irradiation has a direct impact on society by reducing the occurrence of food-borne illness, decreasing food spoilage and waste, and facilitating global trade. Food irradiation is approved in 40 countries around the world to decontaminate food of disease and spoilage causing microorganisms, sterilize insect pests, and inhibit sprouting. A recent estimate suggests that 500,000 metric of food is currently irradiated worldwide, primarily to decontaminate spices. Since its first use in the 1960s the use of irradiation for food has grown slowly, but it remains the major technology of choice for certain applications. The largest growth sector in recent years has been phytosanitary irradiation of fruit to disinfest fruit intended for international shipment. For many countries which have established strict quarantine standards, irradiation offers as an effective alternative to chemical fumigants some of which are being phased out due to their effects on the ozone layer. Insects can be sterilized at very low dose levels, thus quality of fruit can be maintained. Irradiation is also highly effective in destroying microbial pathogens such as Salmonella spp., E. coli, and Listeria, hence its application for treatment of spices, herbs, dried vegetables, frozen seafood, poultry, and meat and its contribution to reducing foodborne illnesses. Unfortunately the use of irradiation for improving food safety has been under-exploited. This presentation will provide details on the use, benefits, opportunities, and challenges of food irradiation. (author)

    In Japan, the first food irradiation research was carried out on the preservation of fish and fishery products. In 1966, the Atomic Energy Commission of the Japanese Government (JAEC) decided to promote the National Project on Food Irradiation and, in 1967, the Steering Committee on food irradiation research in the Atomic Energy Bureau, Science and Technology Agency, selected the following food items as of economic importance to the country, i.e., potatoes, onions, rice, wheat, ''Vienna'' sausage, ''kamaboko'' (fish meat jelly products) and mandarin oranges. The National Project is expected to finish at the end of the 1981 fiscal year. Based on the studies by the National Project, irradiated potatoes were given ''unconditional acceptance'' for human consumption in 1972. Already in 1973, a commercial potato irradiator was built at Shihoro, Hokkaido. In 1980, the Steering Committee submitted a final report on the effectiveness and wholesomeness studies on irradiated onions to the JAEC. This paper gives a brief explanation of the legal aspects of food irradiation in Japan, and the present status of wholesomeness studies on the seven items of irradiated foods. In addition, topics concerning food irradiation research on ''kamaboko'', especially on the effectiveness and a new detecting method for the irradiation treatment of these products, are outlined.

  3. Wholesomeness and safety of irradiated foods

    International Nuclear Information System (INIS)

    Swallow, A.J.

    1991-01-01

    Irradiation with gamma-rays, X-rays or fast electrons can be used to change foodstuffs in beneficial ways or to destroy harmful organisms. Gamma rays do not induce radioactivity in foods, but X-rays and fast electrons can induce short lived radioactivity if sufficiently energetic. This imposes limitations on the energies which can be used, and a short wait between irradiation and consumption may be advisable. Irradiation produces chemical changes in foodstuffs, and some foods are unsuitable for irradiation. With appropriate foods, trials with animals and human volunteers generally show that the product is safe. Some loss in nutritional quality can take place, which could be significant for some individuals, but are unlikely to be important for those on a balanced diet. Irradiation does not eliminate all risk from microbial contamination. Foods to be irradiated should be good quality, and need to be kept under proper conditions after irradiation. Irradiated foods should be appropriately labelled. Tests for radiation would help to enforce necessary controls. If the process is properly carried out on appropriate foods, and all due precautions are taken, irradiated foods are wholesome and safe. 52 references

    Official attitude towards irradiated food is determined by factors such as: level of scientific knowledge, consumer habits, food shortages, agricultural production and technological know-how. To date, 39 countries have accepted the process for one or more food items while 27 nations carry out the process on a commercial basis. Regulations and codes of practice is essential for consumer confidence while uniformity of regulations, at the international level, will enhance international trade in irradiated food items. The internationally accepted Codex Standard on irradiated food and Codes of Practice for the operation of irradiation facilities, adopted in 1983, forms the basis for International regulations and a template for nations in the development of regulations. This paper discusses the basic legal requirements for licensing the process, procedures, facility and the operator and suggests a framework for a national regulation based on experiences of Hungary, Brazil and Israel

    There was a widely held opinion during the 1970`s and 1980`s that consumers would be reluctant to purchase irradiated food, as it was perceived that consumers would confuse irradiated food with food contaminated by radionuclides. Indeed, a number of consumer attitude surveys conducted in several western countries during these two decades demonstrated that the concerns of consumers on irradiated food varied from very concerned to seriously concerned.This paper attempts to review parameters conducting in measuring consumer acceptance of irradiated food during the past three decades and to project the trends on this subject. It is believed that important lessons learned from past studies will guide further efforts to market irradiated food with wide consumer acceptance in the future. (Author)

    There was a widely held opinion during the 1970`s and 1980`s that consumers would be reluctant to purchase irradiated food, as it was perceived that consumers would confuse irradiated food with food contaminated by radionuclides. Indeed, a number of consumer attitude surveys conducted in several western countries during these two decades demonstrated that the concerns of consumers on irradiated food varied from very concerned to seriously concerned.This paper attempts to review parameters conducting in measuring consumer acceptance of irradiated food during the past three decades and to project the trends on this subject. It is believed that important lessons learned from past studies will guide further efforts to market irradiated food with wide consumer acceptance in the future. (Author)

    A food is eatable and innocuous when it has an acceptable nutritional quality, it is toxicological and microbiologically safe for the human consumption. Not one preservation treatment allows to assure this in absolute form. As it happens with other conservation methods, the irradiation produce biological, chemical and physical changes in the treated food. For to check if such changes could cause damages to the health of the consumer, its have been carried out extensive studies to evaluate the inoculate of the irradiated foods. Analyzing diverse toxicity studies to prove the eatability of the irradiated foods, in this work those are presented but important in chronological order. In summary, until today it exists a great heap of tests that they demonstrate without place to doubts that the foods irradiated with a dose up to 10 KGy its are capable for the human consumption, for what can to be concluded that a safety margin exists to consume foods irradiated.

    1979-01-01

    The three international organizations competent in the field of irradiation processing for the preservation of food (FAO, WHO, IAEA), convened, at the end of 1977, an Advisory Group to revise and update the recommendations of a similar group which met in early 1972. The Advisory Group considered how national regulations could be harmonized so as to facilitate the international movement of irradiated food. This publication contains the Report of the Advisory Group, which summarizes the considerations of the Group on regulatory control over the irradiation plant and irradiation of foods, and on assurances for comparability of control (international labelling and documentation). Annexes 1 to 6 are included in order to complete the relevant information on the legal aspects of this subject. They include a Draft General Standard for Irradiated Foods, a Draft Code of Practice for the Operation of Radiation Facilities Used for the Treatment of Foods, Recommendations of a Consultation Group on the Legal Aspects of Food Irradiation, a Listing of the Legislation on Food Irradiation Adopted in Member States (1971-1976), and Model Regulations for the Control of and Trade in Irradiated Food

    2-dodecylcyclobutanone (DCB) and 2-tetradecylcyclobutanone (TCB) are specific radiolytic products in irradiated lipid-containing food and can be used to detect irradiated foods. We previously reported a performance evaluation test in a single laboratory for qualitative detection methods using DCB and TCB as markers for irradiated foods. EN1785, a European Committee Standardization Method, has been widely used for qualitative detection of DCB and TCB in irradiated foods. Here, we evaluated the applicability of EN1785 to camembert cheese, liquid whole egg, sausage and eel grilled without seasoning by using our evaluation test. In this test, extracted lipids from the food were used as negative samples. The lipids spiked with DCB and TCB were used as positive samples. For each food type, 4 negative and 16 positive samples were analyzed by EN1785. All of the negative samples were judged negative and all of the positive samples were judged positive. Thus, EN1785 should be able to detect irradiation in the tested food. Additionally, to confirm the ability of the validated method to detect irradiated food, the same type of food examined above, both unirradiated and irradiated at doses of 0.5-4 kGy, were analyzed by the method. All of the unirradiated samples were judged negative and all of the irradiated samples were judged positive. (author)

  11. Nutritional aspects of food irradiation

    Murray, T.K.

    1981-01-01

    From the nutritional point of view the irradiation of fruits and vegetables presents few problems. It should be noted that irradiation-induced changes in the β-carotene content of papaya (not available to the Joint Expert Committee in 1976) have been demonstrated to be unimportant. The Joint Expert Committee also noted the need for more data on thiamine loss. These have been forthcoming and indicate that control of insects in rice is possible without serious loss of the vitamin. Experiments with other cereal crops were also positive in this regard. The most important evidence on the nutritional quality of irradiated beef and poultry was the demonstration that they contained no anti-thiamine properties. A point not to be overlooked is the rather serious loss of thiamine when mackerel is irradiated at doses exceeding 3 kGy. Recent evidence indicates that thiamine loss could be reduced by using a high dose rate application process. Though spices contribute little directly to the nutritional quality of the food supply they play an important indirect role. It is thus encouraging that they can be sterilized by irradiation without loss of aroma and taste and without significant loss of β-carotenes. Of future importance are the observations on single cell protein and protein-fat-carbohydrate mixtures. The reduction of net protein utilization in protein-fat mixtures may be the result of physical interaction of the components. (orig./AJ)

    1986-01-01

    Consumer attitudes toward food irradiation were evaluated. The influence of educational efforts on consumer concern for the safety of irradiated products and willingness to buy irradiated foods were measured. Demographic and psychological factors were studied in relation to attitudes. An educational leaflet describing current scientific information regarding the safety, advantages, and disadvantages of food irradiation was developed and used in two studies evaluating attitude change. In the first study, attitude change among two groups of consumers with different philosophic orientations was measured. In a second study, the effectiveness of an educational leaflet received through the mail and a poster display were examined. In a third study response to food irradiation was related to value hierarchy, locus of control, innovativeness, and demographic parameters. Initially, subjects showed a higher concern for other areas of food safety, particularly the use of chemicals and sprays on food, than toward food irradiation. After educational efforts, conventional consumers expressed minor concern toward irradiation whereas ecologically sensitive alternative consumers obtained from a food cooperative expressed major concern. A knowledgeable discussion leader lowered irradiation concern among conventional consumers. In contrast, concern among alternative consumers did not diminish when given the opportunity to discuss safety issues with a knowledgeable person

    1991-02-01

    The material available for this review, as well as the Guidelines for Preparing Regulations for the Control of Food Irradiation Facilities adopted by ICGFI, the international Conference Document on the Acceptance, Control of and Trade in Irradiated Food, the draft European Economic Community Directive and the Codex General Standard and Code of Practice on food irradiation suggest that the following aspects may be subject to regulation: Food irradiation licensing, radiation safety, food hygiene, package labelling, inspection, certification for commercial purposes. The purpose of this review is to provide Member States with the information necessary for and special to the control of food processing by irradiation, so as to enable them to ensure that they have or they can adopt effective regulations governing all aspects of trade in irradiated food. Three countries have introduced in their food laws special provisions to regulate the processing of food by radiation. Twenty-three countries have issued such special regulations under the existing statutory authority of one of the executive branches: Seven countries either by reference or by incorporation in whole or in part in their regulations, gave recognition to the Codex Standard and Code of Practice. The absence of such specific recognition should not be interpreted, however, to mean that those countries have not accepted the Codex recommendations. Many provisions seem to have taken the Codex recommendations as a guide. 16 refs

    A national food irradiation forum was held to further promote the use of irradiation for food applications. This offered opportunity for the Department of National Health to announce new legislation for the labelling of irradiated foodstuffs. Subjects which dominated the proceedings included the implementation of labelling legislation and consumer education; cost implications and commercialisation of radurisation; the increasing trend towards the radurisation of processed foodstuffs as opposed to fresh and the future of food irradiation in South Africa. The safety of the irradiation process was stressed. The forum came to the conclusion that South Africa has this technology which has the government's stamp of approval and it is now up to the food industry, the Consumer Council, etc., to educate consumers into realising that they are buying quality products - and that the Radura symbol is a symbol of quality

    Canada has been in the forefront of irradiation technology for over 30 years. Some 83 of the 147 irradiators used worldwide are Canadian-built, yet Canadian food processors have been very slow to use the technology. This paper is an update on the food irradiation regulatory situation in Canada and the factors that influence it. It also reviews some significant non-regulatory developments. (author)

    1983-01-01

    The interest of the industrial food producer is increasing in having the irradiation facility installed in the food processing chain. The throughput of the irradiator should be high and the residence time of the product in the facility should be short. These conditions can be accomplished by electron irradiators. To clarify the irradiation conditions spices taken out of the industrial process, food grade salt, sugar, and gums as models of dry food products were irradiated. With a radiation dose of 10 kGy microbial load can be reduced on 10**4 microorganisms/g. The sensory properties of the spices were not changed in an atypical way. For food grade salt and sugar changes of colour were observed which are due to lattice defects or initiated browning. The irradiation of several gums led only in some cases to an improvement of the thickness properties in the application below 50 deg C, in most cases the thickness effect was reduced. The products were packaged before irradiation. But it would be possible also to irradiate the products without packaging moving the product through the irradiation field in a closed conveyor system.

    One of the most important steps, in order to improve the quality of foodstuffs, in the last forty years is represented by fortified foods. The fortification foods means complementary addition of nutrients to content of foodstuffs. The macro-nutrients (carbohydrates, proteins and lipids) are relativity steady when submitted to irradiation. The micro-nutrients, speciality the vitamins, can be sensible to any method. This work has analysed fortified foods with Fe, Ca, Mg, Zn, vitamin A, riboflavine, vitamin C and folic acid , as well as, the perspective of adjusting the food irradiation process with fortification foods

    A number of design and fabrication aspects of food irradiation facilities have been evolved during past few years. These concepts are basically aimed at providing compact and optimal energy efficient designs for processing of foods. This paper discusses the economics of food irradiation applications and the effects of various parameters on unit processing costs. It provides a model for calculating specific unit processing costs by correlating known capital cost with annual operating costs and annual through puts. 6 figs

    Food irradiation technology is rapidly gaining worldwide acceptance as a promising tool to help alleviate some important food security and safety concerns, and to facilitate the international trade in food. Because of the different priorities that these issues receive in various countries, food irradiation is being considered by developing countries as the technology of choice over chemical fumigants in applications related to the reduction of food losses such as the insect disinfestation of stored staple and export commodities and the inhibition of sprouting of bulb and tuber crops. In contrast, the use of irradiation as a 'cold pasteurization' method to improve the hygienic quality and safety of foods is emerging as the primary field of application in developed countries. Moreover, the use of irradiation as an alternative, non-chemical quarantine treatment for fresh fruits, vegetables and other agricultural commodities entering international trade will no doubt benefit exporting as well as importing countries. 4 figs

    Coghlan, Andy.

    1990-01-01

    This article discusses current arguments for and against the irradiation of food for human consumption. The technique, which involves bombarding batches of food with gamma rays, x rays or accelerated electrons, is claimed to halt spoilage, kill bacteria and thus extend the shelf-life of various foodstuffs. Irradiated foods are at present indistinguishable from non-irradiated food and this problem may not be solved before the government's bill legalizes the process. Opponents claim the technique may not be safe and that the food industry may use it to fool consumers into buying rotten foods. Proponents say that even though many foods, such as poultry, seafood, fruits, vegetables and spices may be treated, it is unlikely that more than a small proportion will be. They reject safety worries as alarmist exaggeration. (UK)

  8. Use of electron accelerators in food irradiation

    International Nuclear Information System (INIS)

    Sanyal, Bhaskar

    2013-01-01

    Preservation of food by ionizing radiations involves controlled application of energy of radiation to agricultural commodities, foods and food ingredients, for improving storage life, hygiene and safety. Insects and microbes cause major economic losses to stored crops. Many of our food products are contaminated with diseases causing germs and toxin producing molds. Without improvement in microbial quality and getting properly treated to overcome quarantine barriers our agricultural products cannot get international markets. In this respect electron accelerators have immense potential in commercial radiation processing of foods. Both low and high dose applications with increased process rates can be achieved using accelerators to cover a wide spectrum of food commodities approved for commercial radiation processing as per the recent gazette notification under Atomic Energy (Radiation Processing of Food and Allied Products) Rule, 2012. The effectiveness of processing of food by ionizing radiation depends on proper delivery of absorbed dose and its reliable measurement. For food destined for international trade, it is important that the dosimetry used for dose determination is carried out accurately and that the process is monitored in accordance with the internationally accepted procedures. Experiments using alanine-EPR system were carried out to optimize the process parameters of 10 MeV electron beam for commercial irradiation of food. Different food commodities namely, mango, potato and rawa (semolina) were irradiated to measure the absorbed dose distribution. The actual depth dose profile in food products and useful scan width of the electron beam were determined for commercial radiation processing of food using electron beam. (author)

  9. Food irradiation: current problems and future potential

    International Nuclear Information System (INIS)

    Kilcast, D.

    1995-01-01

    Food irradiation is one of a set of processing technologies that can be used to increase the microbiological safety and shelf-life of a wide range of foods. Ionizing radiation is used to generate highly active chemical species within the food, which react with DNA. Under normal usage conditions, the food receives a pasteurizing treatment that gives a valuable reduction in common food-spoilage organisms and food pathogens. This review describes how the process is used in practice, including the benefits and limitations. The nature of changes to food components are outlined, together with the development of practical detection methods that utilize these changes. The legislative position of food irradiation is outlined, with the specific example of the introduction of the technology within the UK. The reasons for the slow uptake in the use of the technology are discussed, and the problem of consumer acceptance is addressed. (author)

  10. ENHANCING FOOD SAFETY AND STABILITY THROUGH IRRADIATION: A REVIEW

    Directory of Open Access Journals (Sweden)

    Manzoor Ahmad Shah

    2014-04-01

    Full Text Available Food irradiation is one of the non thermal food processing methods. It is the process of exposing food materials to the controlled amounts of ionizing radiations such as gamma rays, X-rays and accelerated electrons, to improve microbiological safety and stability. Irradiation disrupts the biological processes that lead to decay of food quality. It is an effective tool to reduce food-borne pathogens, spoilage microorganisms and parasites; to extend shelf-life and for insect disinfection. The safety and consumption of irradiated foods have been extensively studied at national levels and in international cooperations and have concluded that foods irradiated under appropriate technologies are both safe and nutritionally adequate. Specific applications of food irradiation have been approved by national legislations of more than 55 countries worldwide. This review aims to discuss the applications of irradiation in food processing with the emphasis on food safety and stability.

  11. Food irradiation: Some regulatory and technical aspects

    1985-10-01

    An Advisory Group by IAEA and FAO on Regulatory and Technological Requirements for Authorization of the Food Irradiation Process was held at IAEA Headquarters in Vienna from 5 to 9 November 1984. The task of the Advisory Group was to advise on the scientific and technological considerations affecting the implementation of the food irradiation process, with particular reference to the facilitation of international trade in irradiated foods and to develop guidance on how the various provisions of the Codex General Standard on Irradiated Foods could be incorporated into national legislation in order to facilitate international trade and avoid the occurence of trade barriers. Separate abstracts were prepared for the various presentations at this meeting

  12. Safety and nutritional adequacy of irradiated food

    International Nuclear Information System (INIS)

    1994-01-01

    The exposure of food to controlled levels of ionizing radiation has a number of beneficial effects, including delaying of ripening, inhibition of sprouting, and inactivation of insects, parasites, helminths, bacteria, moulds and yeasts. However, in general, governments have been slow to authorize the routine use of this technique of food processing, often because of a lack of understanding of what it entails, and a fear of untoward effects on the treated food. This report presents an up-to-date review of the many scientific studies that have been carried out on the safety and nutritional quality of irradiated food. Starting from a brief outlineof the history of food preservation, it goes on to consider in detail the chemistry and potential applications of food irradiation, and to discuss possible ways of determining whether food has been irradiated. Toxicological studies are reviewed, and the effects of irradiation on microorganisms and on the nutritional quality of the food itself are examined. The report concludes that food irradiation is a thoroughly tested technique, that it has not been shown to have any deleterious effects when performed in accordance with good manufacturing practice, and that it can help to ensure a safer and more plentiful food supply by extending shelf-life, eradicating pests and inactivating pathogens

    Food irradiation is at a political crossroad. In one direction, it is moving forward supported by overwhelming scientific evidence of its safety and benefits to economy and health. In the opposite direction, it threatens to be derailed by misleading claims about its safety and usefulness. Whether people will ultimately benefit from the use of irradiation to help fight serious food problems, or whether they will allow the technology to go to waste, will be determined by how successful people are in separating the facts from the fiction of food irradiation

    Recent international moves that are likely to result in an increasing acceptance of irradiated foods are reviewed. Particular attention is given to the activities of the FAO, WHO, Codex Alimentarius and to attitudes in the United States and the Asian-Pacific region. In 1979, the Codex Alimentarius Commission adopted a Recommended General Standard for Irradiated Food. A resume is given of a revised version of the standard that is presently under consideration. However, remaining barriers to trade in irradiated food are briefly discussed, such as legal and regulatory problems, labelling, public acceptance and economic viability

  15. Safety evaluation on irradiated food ingestion

    International Nuclear Information System (INIS)

    1986-01-01

    This paper reports double-blind observations of volunteers who took 35 kinds of irradiated foods as their main diet for 90 days. The subjects consisted of 70 medical students and 8 staff members in the Shanghai Medical University. They were randomly divided into two groups. One group was supplied with irradiated foods, the other acted as controls eating the same food but non-irradiated. The 35 kinds of irradiated foods were grain, meat products, vegetables, fruits, dried fruits etc. The absorbed dose of irradiation from the processed foods varied from 0.1 to 8.0 kGy. The irradiated foods made up 60.3% of the total food intake by weight. Observations during 90 days indicated that the subjects were all pleased with their diets and no adverse effects on their health were seen. Clinical and laboratory examinations included routine blood and urine tests, blood biochemical examinations, hepatic and renal function tests, endocrinological assays, cellular immunity tests, and mutagenetic studies (such as the incidence of polyploid cells, chromosomal structural aberration, rates of sister chromatid-exchanges, micronuclei test, urine Ames' test). These studies showed that the ingestion of these foods are safe for humans

    1993-01-01

    Irradiation or ionization of foodstuffs and agricultural products is an efficient but controversial method which can lead to the post-harvest spoilages reduction, the extension of shelf-life and to provide the food safety. This paper presents the status of food irradiation research and technologies in our country, and throughout the world, too. In Romania the food processing by irradiation (ionization) is not used for commercial purposes and there are not food irradiation plants, yet. There have been performed only research and pilot-experiments, only by the Institute of Food Research in co-operation and using the 6 0C o gamma-ray sources of the Institute of Chemical and Pharmaceutical Research and the Institute of Physics and Nuclear Engineering, both from Bucharest. These experiments have referred both to the basic aspects of the ionizing radiation interactions with the food essential constituents and to the technological aspects of irradiation from different items like: potatoes, onions, garlic, grain, cereals, wheat flour, fresh and dehydrated fruits and vegetables, mushrooms, meat, eggs, spices, ingredients, and biotechnological products. There are also presented the advantages and disadvantages of food irradiation, the world trends in this field and the future in Romania of this technology which was named, in 1989, by the Institute of Food Technologies (US), t he most versatile technology of the 20 -th Century, for tomorrow .

    1978-01-01

    It is apparent that there is a need for protection of the consumer and a need for governmental authorities to insure a safe and wholesome food supply for the population. Based on objective and scientific evidence regarding the safety of food irradiation, national and international health authorities are able to determine whether irradiated food is acceptable for human consumption. Following a thorough review of all available data, the Joint FAO/IAEA/WHO Expert Committee unconditionally approved wheat and ground wheat products and papaya irradiated for disingestation at a maximum dose of 100 krad, potatoes irradiated for sprout control at a maximum dose not exceeding 15 krad, and chicken irradiated at a maximum dose of 700 krad to reduce microbiological spoilage. Lastly, it unconditionally approved strawberries irradiated at a maximum dose of 300 krad to prolong storage. Onions at irradiated for sprout control at a maximum dose of 15 krad were temporarily approved, subject to preparation of further data on multigeneration reproduction studies on rats. Codfish and redfish eviscerated after irradiation at a maximum dose of 220 krad to reduce microbiological spoilage were also approved, based on the results of various studies in progress. Temporary, conditional approval of rice irradiated for insect disinfestation at a maximum dose of 100 krad was based on results of long-term studies on rats and monkies, available in the next review. Due to insufficient data, no decision regarding irradiated mushrooms was made. (Bell, E.)

    Extensive research carried out for more than three decades at Bhabha Atomic Research Centre, and among other laboratories in India had conclusively demonstrated application of food irradiation for commercialization of domestic and export market. The radiation processing has definite economic role to play in food preservation industries in developed countries and developing countries. The possible application of food irradiation in developing countries belong to improvement of the hygienic quality of foods when no other methods are available to achieve this purpose, replacement of chemical treatments, improvement of shelf life of certain fruits, improvement of sensory quality, potential application to a quarantine treatment

    The benefits and concerns about treating foods with ionizing radiation are reviewed. Radioactivity cannot be induced in foods by treatment with gamma rays from 137 Cs or 60 Co, X-ray sources of 5 MeV or lower energy, or electrons of 10 MeV or lower energy. The evidence supports the safety and efficacy of using ionizing radiation for insect disinfestation of grains; dried spices, vegetables and fruits; and fresh fruit. Species and dose dependent phytotoxic and vitamin changes may occur in some fruits at greater doses than currently approved by the U.S. Food and Drug Administration. Irradiation can inactivate protozoan or helminth parasites and significantly decrease the probability of viable food-borne bacterial pathogens in fish, poultry, and red meats. The titers of amino acids, fatty acids, and vitamins of chicken meat sterilized by thermal, electron-beam, or gamma radiation are presented. On the whole, the data support the safely and efficacy of the process

    2014-01-01

    The potential benefits of food irradiation are yet to be realized due to slow progress in the commercialization of the technology. Processing food with ionizing radiation has encountered several barriers, one of which is the belief that consumers will not purchase irradiated food and a consequent caution among food retailers and producers. There is sufficient evidence that consumers will purchase irradiated foods when offered at retail in contrast to the data from many surveys of general public opinion. Communicating this evidence to food retailers and producers is essential if a major barrier to a greater use of the technology is to be overcome. - Highlights: • Food irradiation is safe and can benefit food safety, security and trade. • Commercial use remains limited. • The food trade tends to believe consumers will not buy irradiated food. • There is good evidence that consumers buy irradiated food when it is offered. • Demonstrating this evidence to industry is vital for commercial success

    The number of products being radiation processed worldwide is constantly increasing and today includes such diverse items as medical disposable, fruits and vegetables, spices, meats, sea foods and waste products. Their range of products being processed has resulted in a wide range of irradiator designs and capital and operating cost requirements. The paper discusses the economics of food irradiation applications and the effects of various parameters on unit processing costs. The food under investigation were smoked fish, spices and dried vegetables. It provides a model for calculating specific unit processing costs by correlating know capital costs with annual operation costs and annual throughputs. It is intended to provide the investors with a general knowledge of how unit processing costs are derived, and enough information to assist in the choice of the irradiator model best suited for specific needs

    To detect irradiated foods, ESR method is most frequently used, but its application is limited to a very narrow range of foods. So, the authors have attempted to introduce ortho-tyrosine method in this area. In this study, the possibility that ortho-tyrosine may be generated during analysis was examined and the results were compared with those obtained by other detection methods. The production of ortho-tyrosine by γ-ray was demonstrated to be due to secondary effects of the irradiation. The lower limit of this method was thought to be in a range, 0.1 - 0.2 kGy in consideration of individual difference depending on the method of processing, measurement, etc. The specificity and sensitivity of ortho-tyrosine method were remarkably improved compared with other methods. Realization of automatic analysis resulted to exclude the analytical difficulties due to labeling. However, the sensitivity of ESR method was much higher than that of ortho-tyrosine method. The present results show that further improvement of ortho-tyrosine method is necessary for practical application. (M.N.)

    History has shown that man has continued to search for methods to protect his food from various spoilage agents. Traditional methods of food preservation such as drying, salting, fermentation, have been known for centuries and are being practised even today. Within the past century, modern technologies such as canning, freezing, refrigeration, the use of preservatives and pesticides, have further equipped man with an arsenal of methods to combat food losses and to increase the quantity, quality and safety of our food supplies. The most recent technology, irradiation, has gone through a great deal of research and development in the past 40 years and has shown a strong potential as another method for food preservation. As irradiation is still not familiar to the public at large, this paper attempts to inform scientists, officials, representatives of the food industry, and consumers of the global situation of the safety, benefits and applications of food irradiation by answering common questions often asked about the technology today. Special emphasis will be placed on the possible contribution of food irradiation to ASEAN

    There is no item of more primary importance to the welfare of the human race than food. It has long been realized that even small increases in the quality and/or quantity of food mean great benefits to people everywhere, particularly to those who are undernourished or on the threshold of starvation. Therefore, the application of food preservation technology to prevent food losses has become a major factor in solving the world's food problems. Some of the chemical additives used to preserve food have caused harmful effects on the well-being of the consumer, but the newly-developing commercial treatment of a number of food products with low doses of ionizing radiation has been shown to be technologically advantageous and economically viable.The Food Preservation Section of the Joint FA O/lAEA Division decided to set up a data system whereby wholesomeness information on irradiated food can be easily obtained and disseminated by means of publication. The data will be related to toxicological safety, nutritive value and microbial innocuity. To do this the Division has sent a questionnaire to institutes and scientists involved in programmes dealing with wholesomeness of irradiated food, requesting them to provide information on investigations already completed, on those which are currently in progress and on programmes projected for the future. Based on the responses received, a list of wholesomeness investigations recently carried out in Member Countries on different food items, can be found. Summarily it can be stated that the results from these investigations do not indicate any detrimental effects on health. Detailed data will be published periodically by the International Project in the Field of Food Irradiation in 'Food Irradiation Information'. The project has been established under the auspices of FAO, IAEA and OECD (NEA) with 22 countries at present contributing financially to the Project

    Viet Nam has emerged as one of the three top producers and exporters of rice in the world. Tropical climate and poor infrastructure of preservation and storage lead to huge losses of food grains, onions, dried fish and fishery products. Based on demonstration irradiation facility pilot scale studies and marketing of irradiated rice, onions, mushrooms and litchi were successfully undertaken in Viet Nam during 1992-1998. Irradiation technology is being used commercially in Viet Nam since 1991 for insect control of imported tobacco and mould control of national traditional medicinal herbs by both government and private sectors. About 30 tons of tobacco and 25 tons of herbs are irradiated annually. Hanoi Irradiation Centre has been continuing open house practices for visitors from school, universities and various different organizations and thus contributed in improved public education. Consumers were found to prefer irradiated rice, onions, litchi and mushrooms over those nonirradiated. (author)

    The last decade has witnessed significant advancement of the acceptance of food irradiation processing. At present 37 countries have approved one or more food items for human consumption and 25 countries have commercialized this process. More developing countries are showing keen interest to introduce irradiation processing in order to reduce post-harvest food losses, to increase export potentials and to ensure safety of food to their people. Although progress towards acceptance of food irradiation by the industry is slow, actual market trials have shown that once consumers have understood this technology, they are willing to buy irradiated foods. This paper deals with the latest developments in the field of food irradiation with particular reference to legislation, consumer acceptance, commercialization and potential application in developing countries. This paper also deals with the role played by the International Organizations, aimed at facilitating the acceptance of food irradiation.

  5. Toxicological studies on irradiated food and food constituents

    International Nuclear Information System (INIS)

    Schubert, J.

    1978-01-01

    Selected aspects of the genotoxicology and chemistry of irradiated foods and food components are critically examined and compared with other food processing operations such as cooking, and intentional use of food additives. For example, it is estimated that if 10% of an average daily diet contained irradiated (<1.0Mrad) foods, the daily consumption of radiolytic products would be 2-20mg/d compared with a total of approximately 4000mg/d of intentional food additives and approximately 80mg/d of toxic inorganic and organic environmentally derived contaminants. Several recommendations for the genotoxicological testing of irradiated foods are given, including: (1) that feeding tests include a control diet consisting of food processed by one of the standard methods such as thermalization; (2) that more use be made of positive controls so as to have a 'built-in' measure of sensitivity and responsiveness; (3) that a battery of in vitro and in vivo short-term mutagenicity tests be performed prior to the carrying out of the long-term feeding tests; and (4) that an irradiated food be tested after it is cooked in the manner normally consumed, which may, of course, include the raw or uncooked state as well. An outline of current genetic-toxicological testing schemes is provided and examined. Emphasis is given to a modification in the protocols for the Ames mutagenicity tests leading to a reduction in the evidence of false positives and false negatives. Also described is a procedure for systematically studying combined or interactive effects, acute or chronic, which requires no more effort than that needed for testing a single agent and which yields complete dose-response curves. It is concluded that food irradiation, as a physical process, appears more advantageous from the genotoxicological, chemical, and pollution aspects than well-accepted, but actually rarely tested, physical processes such as canning.

    In view of the enormous health and economic consequences of foodborne diseases, the World Health Organization (WHO) encourages its Member States to consider all measures to eliminate or reduce foodborne pathogens in food an improve their supplies of safe and nutritious food. With the wholesomeness of irradiated food clearly established by extensive scientific studies, food irradiation has important roles to play in both ensuring food safety and reducing food losses. Food irradiation may be one of the most significant contributions to public health to be made by food science and technology since the introduction of pasteurization. Because the promotion of a safe, nutritious and adequate food supply is an essential component of its primary health care strategy, WHO is concerned that the unwarranted rejection of this process may endanger public health and deprive consumers of the choice of foods processed for safety.

    1996-01-01

    Food irradiation is a technique which is increasingly being recognised as an effective method for reducing post-harvest food losses, ensuring hygienic quality of food and facilitating wider trade of certain food items. Irradiation of food may be used to achieve a variety of desirable objectives including the following which are classified according to the average radiation dose requirement: i. Low dose application (up to about 1 kg), for inhibition of sprouting in yams, potatoes, onions, etc. insect disinfestation and delay of ripening in fruits. ii. Medium dose applications (about 1-10kgy), for reduction of micro-organisms and improvement in technological properties of food. iii. High dose application (about 10-50kgy) which is used for sterilization for commercial purposes and elimination of viruses. From the point of view of food safety the energy level of the radiation applied to food is the most important characteristics that has to be regulated in order to prevent the possible formation of induced radio activity. Fortunately, the most commonly used isotopic sources 60Co and 137Cs; and machine sources such as the electron beam generators, induced radio activity is negligible, short lived and lower than that causing radio activity. This and other scientific and technical aspects of the commercial application irradiation technology with respect Nigeria have been examined in this paper along side with those of its politics and social policy

    Research and development work in food irradiation over the past several years has been essentially directed towads answering all possible questions in respect of the suitability of the process, quality of materials and safety for human use. A major effort was indeed, around the toxicological evaluation, till it was recognised internationally that irradiated items of food do not present any health hazards. This recognition along with the awareness of the hazards in the use of chemicals has resulted in a renewed interest in the use of radiations for preservation of food. Radiation preservation of food would reach the stage of practical application with additional information on design and functional aspects of radiation sources, appropriate for specific commodities. Each items has a particular dose requirement depending on the purpose of irradiation and the type of handling. 21 refs. (author)

    We tried to detect whether foods were irradiated or not by the o-tyrosine method and the mtDNA method. The o-tyrosine method was applied to four kinds of meat (beef, pork, chicken and tuna). The results showed the linear relation between amount of o-tyrosine and dose (0-10 kGy). However, small amount of o-tyrosine were produced in some cases which application of the method summed to be very difficult because small difference between irradiated foods and untreated foods. Possibility of mtDNA method was investigated. Work and time for separation of mitochondria and extraction of DNA were reduced by a protease-solid phase extraction method. By PCR method, accurate mtDNA could be detected from very small amount of DNA. The irradiation effect is able to detect from 50 Gy. (S.Y.)

  15. Legal, administrative and psychological barriers against industrial application of food irradiation and the trade in irradiated food

    Cornelis, J.C.

    1977-11-01

    In the author's view, the legal and administrative barrier against industrial application of food irradiation and trading can be described as follows: even if public health authorities in each country concerned, are convinced by the scientific evidence that the food irradiation process is acceptable, they will only be willing to accept irradiated food exported from another country if they are assured that irradiation has been performed in an approved and acceptable manner. The psychological barrier which is more complex consists of three interconnected factors: attitude of the public towards irradiated food, confidence of national authorities in the capability of food processors, the lack of cooperation between government Agencies.

    For some special cases, the use of low energy electrons has advantages over the use of gamma-rays or higher energy electrons for the direct irradiation of food. These advantages arise from details of the interaction processes which are responsible for the production of physical, chemical and biological effects. Factors involved include depth of penetration, dose distribution, irradiation geometry, the possible production of radioactivity and costs

    As shortages of food and energy still continue to constitute the major threats to the well-being of the human race, all actions aiming at overcoming these problems must be assigned vital importance. Of the two complementary ways of solving the food problem (i.e., increasing the production of food and decreasing the spoilage of food) a novel method designed to contribute to the latter purpose has been discussed at this symposium hosted by The Netherlands and held under the aegis of the Food and Agriculture Organization of the United Nations, the International Atomic Energy Agency and the World Health Organization. Progress made since the last symposium of this kind (Bombay, India, 1972) was reviewed from the technological, economic and wholesomeness points of view by participants from 39 countries (60% of the latter were of the developing world). From the reports presented on the use of radiations to control physiological changes in plants, feasibility of radiation preservation of potatoes, onions, garlic, as well as of some tropical and subtropical fruits (mangoes, papayas, litchis and avocado) was confirmed. For potatoes, onions and mangoes, optimal conditions of treatment and storage were established on a larger scale, combined with sizeable consumer trials. Combinations of ionizing radiation with chemicals (salycilic acid, for potatoes), and physical agents (ultraviolet rays, for papayas) have been reported to be successful against the incidence of rot. A considerable number of papers dealt with the control of microbiological spoilage of foods. Work since 1972 has shown that radurization of fruits and vegetables (bananas, mangoes, dried dates, endive, chickory, onions, soup-greens), meat, poultry, marine products (mackerel, cod and plaice fillets, shrimps), decontamination of food ingredients and food technology aids (enzyme preparations, proteins, starch, spices), radappertization of meat and animal feedstuffs as well as combination treatments with salt, heat

    Many of the foods that will be consumed in the 21st century have not yet been invented. New methods of production need new methods of conservation. Food irradiation by gamma radiation or electron beam is a new technology. The intensive production methods of today lead to several potential dangers. For example - if just one chicken is diseased this bird can contaminate all of one days' production at the slaughter house - on average 300,000 birds per day. One has to have conservation methods that can decontaminate the poultry meat. Irradiation is a method that achieves this. The consumer is becoming more and more sophisticated and demanding with regard to the quality of food products, rejecting chemical additives for example, irradiation is a physical method of conservation, this means that there is no residue left in the product, and that there are no changes in the physical characteristics of the food. This paper examines the use of irradiation technology as a food conservation method in today's industry. (author). 4 refs., 2 tabs

    2005-01-01

    In the last years, an increasing amount of people is consuming more fruits, vegetables, seeds and sprouts, with the health effects of food in mind. Otherwise, the accepted shelf food safety found in some countries led to a growing trust in the product's hygienic quality, that leads to behaviors like opening a package and immediately consume the contents. Besides the well disseminated knowledge of good cooking practices, the lack of time, found mainly in big cities, may take to the dinning tables food with an increasing potential of pathogenic organisms contamination. For instance, the alfalfa, beam, clover and radish sprouts caused many reported Salmonella and E. coli outbreaks in countries like the USA, United Kingdom, Japan, Sweden, Finland, Canada and Denmark. Many of the likely source of contaminations were the contamination of the seeds before sprouting. To control these contaminations, the irradiation doses over 1 kGy is effective and the association of irradiation and chemical treatments is being studied. The bacteriological control performance of the irradiation becomes this technique one of the most applied to dry herbs and spices witch, without adequate treatment, could be important sources of foodborne outbreaks. Good production, handling, packing and distribution practices may, with the use of ionizing radiation to reach the desired bacteriological inactivation or decontamination level, significantly contribute to the necessary food safety, allowing it to be safely ready to eat.

    By electron spin resonance (ESR) spectroscopy, we revealed free radicals in γ-ray irradiated foods; black pepper, green coffee bean and ginseng. We also analyzed the decay behavior of radiation induced free radicals during storage of irradiated foods. The ESR spectrum of experimental irradiated foods consists of a sextet signal centered at g=2.0 and a singlet signal at the same g-value position and a singlet signal at g=4.0. The singlet signal at g=2.0 is originated from organic free radicals and its peak intensity showed the dependence of γ-ray irradiation dose levels. The signal intensity was decreased during storage. Only after 3 hours of radiation treatment the peak intensity was decreased fast and after that the intensity was decreased slowly. The relaxation times, T 1 and T 2 , of radiation induced free radicals showed the variations before and after irradiation. During long time storage period it was shown that T 1 was increased and T 2 was decreased. By analysis of decay process using the simulation methods based on the theory of reaction speed, it is considered that at least two kinds of radicals were induced in irradiated foods during long time storage.

    The use of ionizing radiation in food processing has received increased interest as a means of reducing the level of foodborne pathogens. This overview discusses the regulatory issues connected with the use of this technology in the United States. Several recent changes in the FDA's review process are discussed. These include the current policy that utilizes an expedited review process for petitions seeking approval of additives and technologies intended to reduce pathogen levels in food, and the recent USDA rule that eliminates the need for a separate rulemaking process by USDA for irradiation of meat and poultry. Recently promulgated rules and pending petitions before the FDA associated with the use of ionizing radiation for the treatment of foods are also discussed along with the current FDA labeling requirements for irradiated foods and the 1999 advanced notice of proposed rule on labeling. Another issue that is presented is the current status of the approval of packaging materials intended for food contact during irradiation treatment of foods

    Gamma irradiation was applied to chickens for evaluation of their possible genotoxicity, acute toxicity, four-week oral toxicity and nutritional safety. The results were negative in the bacterial reversion assay with S. typhimurium TA98, TA100, TA1535, TA1537. Clastogenic effects of the irradiated samples tested were not shown in vivo mouse micronucleus assay and in chromosomal aberration tests with CHL cells. In an acute toxicity test, the maximal dose of 5,000 mg/kg did not change any toxic parameter examined in this study. In four-week oral toxicity study, appearance, behavior, mortality, food and water consumption of mouse of treated groups were not affected during the experimental periods(four-weeks). In urine analysis, in hematological examination as well as in serum biochemical experiment, no significant differences were found between the control and treatment groups. Although minor changes in some hematological and biochemical parameters were observed, they were in the normal range and were not dose dependent. In nutritional safety, the proximate composition of foods were not significantly changed by irradiation dose. No significant difference in the components of fatty acids were observed by gamma irradiation. In general, the amount of released free amino acid was not significantly changed by gamma irradiation. There was no difference in total amino acid content between non irradiated and irradiated samples. The SDS electrophoresis patterns of samples were not significantly different between nonirradiated and irradiated samples. The major mineral compositions of chicken were phosphorus, potassium, sodium, magnesium. The content of mineral was not significantly changed by gamma irradiation. 58 refs., 11 figs., 16 tabs.

    Safety tests of radiation irradiated foods started as early as from 1967 in Japan and genotoxicity tests in the Hatano Res. Inst., from 1977. The latter is unique in the world and is reviewed in this paper. Tests included those for the initial injury of DNA, mutagenicity, chromosomal aberration and transformation with use of bacteria, cultured mammalian cells and animals (for chromosomal aberration, micronucleus formation and dominant lethality). Foods tested hitherto were onion, rice, wheat and flour, Vienna sausage, fish sausage (kamaboko), mandarian orange, potato, black pepper and red capsicum, of which extract or powder was subjected to the test. Irradiation doses and its purposes were 0.15-6 kGy γ-ray ( 60 Co) or electron beam by the accelerator (only for the orange), and suppression of germination, pesticide action or sterilization, respectively. Genotoxicity of all foods under tested conditions is shown negative. (N.I.)

    Irradiation combined with other processes can contribute to insuring food safety to consumers and controlling severe losses during transportation and commercialisation. We have demonstrated that using in synergy with other treatments; a lower dose could be used to eliminate pathogenic bacteria and permit a better protection of the sensorial quality and to prolong the shelf life of foods. Results indicated that some bacteria are more sensitive to irradiation under modified atmosphere (MAP) and the presence of active compound can increase the bacterial radiosensitivity by more than 4 times under air and by more than 10 times under MAP. Mild heat treatment or addition of natural antimicrobial compounds before irradiation treatment has also permitted an increase of Bacillus cereus radiosensitization. An increase of the bacterial radiosensitization of 1.5 and 1.56 was respectively observed. The effectiveness of the use of edible coating containing natural antimicrobial compounds, modified atmosphere packaging (MAP) or mild treatment before irradiation treatment was demonstrated in order to inactivate Listeria monocytogenes, Salmonella typhimurium, Escherichia coli and Bacillus cereus growth or B. cereus spore germination, to increase the bacterial sensitivity to irradiation, to reduce the water loss and to extend the shelf life of the food when stored at 4 deg C. Also, the use of edible coating previously crosslinked by irradiation have permitted a better control of the active compounds release. Studies of combined treatments were used in ready to eat vegetables, fruits and meat products. (author)

    Irradiation is a mature technology for many uses, such as medical product sterilization, crosslinking of plastics, application of coatings, stabilization of natural and synthetic rubbers prior to vulcanization, and in plant genetics. It also has many potential applications in the food and agriculture industries, especially in the postharvest activities associated with processing, storing, and distribution and in utilization and consumption. The safety of food irradiation has been thoroughly studied and established by distinguished scientists of international stature and unimpeachable credentials. Approximately 30 countries permit food irradiation and it is commercially used in 21. Parasites are of serious concern since their impact on human health and economic productivity is significant, especially in developing countries with sanitation and food control problems. Parasites in meat and fish can be rendered sterile or inactivated with irradiation, and the potential for improved human health is significant. The second area for immediate use of irradiation is in meeting plant quarantine requirements. The benefits described above and the approval of the scientific community are moving the technology toward greater utilization

    1980-06-01

    Studies are carried out on the wholesomeness of irradiated food with special reference to gamma irradiation (0.75 kGy) maize, (1 kGy) walnuts and (2 kGy) prune-plums. These include physico-chemical changes in the food constituents as well as toxicity and mutagenic effects on animals after long-term feeding test. The results indicate an increase of the carbonyl compounds after irradiation in all studied foodstuffs, but there is not significant difference in the number of the new-formed carbonyl compounds when compared with controls. Biomedical investigation are carried out to define any toxicity, consideration being given to both direct effects in adult or growing organisms and to effect in their progeny. Effects of gamma irradiated diet, including maize, walnuts and prune-plums, exposed to the above mentioned doses fed to three consecutive generations of mice have been studied. A 35% addition of irradiated feed to standard diet is shown to produce no deleterious effects as judged by mean litter size, body weight at weaning, adult body weight and organ weight, haematological measures and some enzyme activities

    Radiation processing of foods and allied products is one of the important techniques to extend shelf-life. The success of this technology depends on the adequate dose delivery to the food products. The absorbed doses are functions of several irradiation parameters based on the design of the facility. The variable bulk density of the process load is of paramount importance in determining the dose uniformity. Bulk densities of the product in the range of 0.01 to 0.75 gm/cc were prepared and its influence on absorbed dose was studied in a "6"0Co based food package irradiator. The results established that the bulk densities of the process loads would considerably change the absorbed doses and dose uniformity. The data would be useful to the facility operators to take adequate decision in dosimetry procedures. (author)

    In a reply to a critical article on food irradiation, Dr Ari Brynjolfsson of the International Facility of Food Irradiation Technology contends that the food industry has no interest in supporting the nuclear industry by using nuclear wastes as radiation sources - high voltage electron generators are more practical and economic. Also World Health Organization Toxicologists have concluded irradiated food is safe toxicologically, nutritionally and microbiologically. A study in India found no difference in polyploidy in children fed irradiated or non-irradiated food. In reply Dr Richard Piccioni suggests that the cancer risk from irradiated food is high, that the Indian study showed that irradiated food can cause an increase in polyploidy in well-fed adults, and suggests that Cs-137 from nuclear reactors will be used in food irradiation.

  6. International standards, Agreements and Policy of food Irradiation

    International Nuclear Information System (INIS)

    Roberts, P.B.

    1997-01-01

    There are few internationally recognised standards and agreements related to irradiated foods. Codex Alimentarius has its General standard for Irradiated foods. This sets standards for the production of irradiated foods that are safe and nutritionally adequate. Guidelines for the proper processing of foods by irradiation are covered in the Codex Recommended International Code of Practice for the Operation of Radiation Facilities Used for the Treatment of Food. For irradiation as a quarantine treatment for fruit, vegetables and other plants, the relevant international organization is the International Plant Protection Convention (IPPC), IPPC has no standards or guidelines for irradiation treatments. However, regional organizations within IPPC are moving towards recognition of irradiation as a technically viable and effective method of insect disinfestation. Especially notable are actions within the North American Plant Protection Organisation (NAPPO). NAPPO has endorsed a standard on the use of irradiation as a quarantine treatment. Other speakers have provided considerable detail on the Codex standard and on the situation with regard to quarantine issues. In this talk I will concentrate on irradiated foods as commodities that will be traded internationally in increasing amounts as we approach the next century. International trade is governed by bilateral arrangements. However, these arrangements should be consistent with the overarching multilateral agreements of the World trade Organization (WTO). The WTO Agreements do not refer directly to irradiation or irradiated foods. However, in this talk I will try to interpret the implications of the Agreements for trade in irradiated food. (Author)

    Progress made during these 30 years in the field of radiation treatment of food is reviewed by describing features of the process including elementary processes, quality control of the products and the dosimetric techniques widely employed. The Co-60 gamma-ray irradiation facilities to be used for radiation-sterilization of medical supplies and food preservation are presented. For electron beam irradiation, accelerators for processing with the energy from 0.3 to 10 MeV are generally employed. The electron-guns, the method of acceleration such as rectification, types of acceleration as Cockcroft-Walton, dynamitron, or linear acceleration and X-ray producing facility, with various countermeasures for safety management, are briefly explained. The concepts of dose and traceability are given. The dosimeters including reference dosimeter and routine ones with validation are explained. (S. Ohno)

    The study of food irradiation in Japan begun in 1955. The national project investigated the irradiation technologies and the irradiation effects on seven foods such as potato, rice, wheat, wiener wheat, orange and processed marine products. Only irradiation technique of potato has been made practical use since 1974. After this project, some researches on food irradiation were reported. For examples, the radiation sterilization of feed, spice, grapefruit, frozen shrimp, cock and beef. Some databases of irradiated foods are opened. The biological and radiochemical effects of gamma ray, X-ray and electron ray on food has not been observed. New aspects of irradiation, the measures for food poisoning, food safety and sanitary, has a great deal of public attention. In order to prepare the distribution of irradiated food in the world, we should develop a detection method, prevention technology of bad-tasting, quarantine treatment technology and control technology of irradiation process. History of food irradiation in Japan and future subjects are explained. (S.Y.)

    2010-01-01

    Food irradiation is an efficient technology that can be used in the conservation of foods. However, consumers' knowledge about irradiated foods has proved insufficient resulting in low acceptance of such foods. Considering that dietitians and nutritionists are the qualified health professionals to guide patients and consumers towards the ingestion and selection of foods, this study aims to evaluate the knowledge and views about radiated foods of professors of nutrition working in higher education institutions in the city of Belo Horizonte - MG, Brazil. A total of 86.4% out of the 66 participants had general knowledge about irradiated foods. However, 71.2% were not familiar with the process, 75.8% were totally unaware of the specific legislation, 21.2% were not sure of the purposes of irradiation, 12.1% considered irradiated foods radioactive, and 31.8% believed that food irradiation results in the reduction of the nutritional value of foods. Irradiated foods would not be rejected by professionals with Ph.D. degree, but they would be rejected by five masters and six experts questioned. The study concluded that the current higher education of future dietitians and nutritionists has been provided without the minimum necessary knowledge regarding irradiated foods corroborating the negative view of consumers about this kind of food.

  11. Food irradiation - pros and cons

    International Nuclear Information System (INIS)

    1983-01-01

    The use of ionising radiation for food preservation is a much-disputed topic, both among experts and among consumers. Pros and cons of this issue were discussed in detail at the consumers' forum. Professor Dr. Johannes Friedrich Diehl, Director of the Institute for Biochemistry of the Food Research Centre, Karlsruhe, is a well-known supporter of the new method of food preservation; he sees advantages in the radiopreservation of food because, for example, losses due to inedibility are reduced, the danger of salmonellosis is decreased, just as the use of chemicals. He thinks this method to be without danger to health, shown by many years of experience. Opponents to food irradiation like Prof. Dr. Konrad Pfeilsticker, Professor for food science and food chemistry at the Bonn University deem the method to be unnecessary and raise the problem of qualitative changes caused in the food. In the course of the discussions, the pros and cons seemed to balance each other out. (orig./AJ) [de

    In view on the enormous health and economic consequences of foodborne diseases, irradiation decontamination and disinfestation of pathogen-containing foods must be considered one of the most significant recent contributions to public health made by food science and technology. Food irradiation has an important part to play with in the promotion of food safety and in the reduction of food losses. The unwarranted rejection of the process, often based on a lack of understanding of what food irradiation entails, may hamper its use in most countries that could benefit most

    Highlights: ► Different considerations are required in PSA for Non-Reactor Nuclear Facilities. ► We carried out PSA for food irradiation facility as a part of safety evaluation. ► The results indicate that the fatal exposure risk is below the ‘acceptable risk’. ► Adequate operator training and observing good safety culture would reduce the risk. - Abstract: Probabilistic safety assessment (PSA) is widely used for safety evaluation of Nuclear Power Plants (NPPs) worldwide. The approaches and methodologies are matured and general consensus exists on using these approaches in PSA applications. However, PSA applications for safety evaluation for non-reactor facilities are limited. Due to differences in the processes in nuclear reactor facilities and non-reactor facilities, the considerations are different in application of PSA to these facilities. The food irradiation facilities utilize gamma irradiation sources, X-ray machines and electron accelerators for the purpose of radiation processing of variety of food items. This is categorized as Non-Reactor Nuclear Facility. In this paper, the application of PSA to safety evaluation of food irradiation facility is presented considering the ‘fatality due to radiation overexposure’ as a risk measure. The results indicate that the frequency of the fatal exposure is below the numerical acceptance guidance for the risk to the individual. Further, it is found that the overall risk to the over exposure can be reduced by providing the adequate operator training and observing good safety culture.

    Issues as relevant to wide scale application of food irradiation are presented in this paper to provide current status of the technology. Global development on key issues such as public acceptance, public health improvement, safety and wholesomeness, regulatory aspects, potential application of the technology to ease quarantine problems in the trade of food and agricultural commodities as a viable alternative to fumigation with methyl bromide have been presented. Irradiation ensures the hygienic quality of food and extends shelf-life. Many international organizations and respected regional/national bodies agree on the merits of the technique and valuable contribution that the process can offer to safeguard the food supply worldwide. Codex General Standard for irradiated food and the associated Code of Practice for operation of the irradiation facilities used for the treatment of foods adopted in 1983 forms the regulatory basis for commercial utilization of the processing technology. More than 40 countries of the world have Standards/Regulations to process one or more food products by the irradiation process. Efforts are underway to harmonise national regulations on food irradiation to remove obstacles for international trade of irradiated products. There is a rapid development on commercial application of food irradiation in the USA and elsewhere in the past few months. There are already several existing commercial irradiators available for treating food in the USA and many more are planned to be built. Such commercial food irradiation facilities are also in different stage of development in Brazil, India, Mexico, Thailand, People's Republic of China, Republic of Korea. Roles of irradiation ensuring food safety, contributing food security and facilitating trade are more and more recognized in developed and developing countries alike. (author)

    1996-01-01

    In Korea, the health authorities and food industry emphasize the need of sanitary food production, which is mainly resulted from the recent growing of consumer's interest in the safety of food. For that reason, development of a new alternative technology of chemicals currently used for decontamination and disinfestation has become an urgent task in the domestic and worldwide food industry. Furthermore, the improvement of quality and manufacturing process of processed foods is a requisite for winning the competition in export fields. Irradiation technology being practically applicable in the food industry has been well established on the basis of more than 40 years of R and D work in the fields of the increasing availability of food-stuffs, sanitary food production and quarantine treatment in a food trade. The wholesomeness of irradiated foods has been officially approved in 37 countries, of which 25 countries are commercially utilizing food irradiation technology. The first commercial irradiator in Korea (18.5 PBq : 500 kCi 60 Co, max. cap ; 4 MCi) was established at Kyungki-do, Yeoju-gun by Greenpia Tech. Inc. with the technical assistance of Korea Atomic Energy Research Institute in June 1987. As of 1996, thirteen irradiated food groups (above 25 items) have been domestically approved for human consumption and an industrial irradiation facility is also available. However, the promotion of consumer acceptance toward irradiated foods is considered as a confronted subject to be studied for a commercial utilization of this technology

    This paper deals with Micrococcus radiodurans, Arthrobacter radiotolerance, etc., which were isolated and discovered as radioresistant microorganisms. As for the explanation of the mechanism of radioresistance of these microorganisms, the consideration that these organisms have marked repair power of the damaged DNA and have many opportunity to repair the damaged DNA because of their long fission term were cited. The relationship between the radioresistance of microorganisms and food irradiation was also mentioned.

    The mutagenicity of ''standard'' food pellets from three different suppliers was tested after radappertization and after sterilization with steam, respectively. The histidine-deficient mutants G-46 and TA-1530 of salmonella typhimurium were used as indicators in a hostmediated assay. The mutant TA-1530 showed a highly sighificant increase of the back-mutation frequency after feeding with pellets irradiated with 3 Mrad gamma radiation. There were, however, large quantitative differences between the products of different suppliers. (G.G.)

    In Denmark food irradiation is not allowed. However, with the consideration within EEC about directives regulating food irradiation and the development of methods for detection, it has been found necessary to ascertain that illegally irradiated foods are not found on the Danish market. Irradiation of spices is allowed in many countries even without being declared in the foods. It thus seemed logical to begin the control of food irradiation by screening a number of spices. This resulted in 1992 in the assessment of 105 samples and in 1993 of 48 samples. (author)

    Recent approvals of food irradiation processes by the U.S. Food and Drug Administration have led to a search for packaging approved for use with ionizing radiation. Though 13 packaging materials were approved several years ago as food contactants for gamma irradiation up to 10 kGy at refrigeration temperatures and 4 packaging materials were approved for up to 60 kGy at cryogenic temperatures, no currently used packaging is approved for irradiated foods. Extensive research was conducted by the U.S. Army and others on the suitability of both flexible packaging and metal cans for packaging irradiated foods. The results of the studies of packaging for irradiated foods will be described and discussed in context of currently used packaging materials for non-irradiated meats and poultry

    Electronic accelerator was applied to instead of cobalt sources for food irradiation, to keep food quality and to improve the effect of the treatment. Appropriate accelerator parameters lead to optimal technique. The irradiation effect is associated with the relationship between uniformity and irradiating speed, the effect of cargo size on radiation penetration, as well as other factors that affect the irradiation effects. Industrialization of electron accelerator irradiation will be looked to the future. (authors)

    1978-01-01

    In the task of alleviating the distress caused by the world-wide food shortage it is essential to preserve what has been grown and harvested in the fields. Clearly all suitable methods for preserving agricultural produce and food should be made use of. In this context treatment with ionizing radiation has proved its value as an environmentally clean, physical method of food preservation which is low in its energy requirement, but the volume of food being processed in this way is still low. The introduction of food irradiation on a global basis poses certain economic, legal, regulatory and health-related questions, the solution of which requires close international collaboration. Such collaboration between many international, intergovernmental and national organizations began over a decade ago. The need for dissemination and discussion of information gained through research and development work on this subject became apparent, and a number of inter-regional meetings were held. The last international symposium on the topic was held jointly by FAO and the IAEA in 1972 in Bombay. To review progress made since then, FAO and the IAEA, together with WHO, convened the present Symposium on 21-25 November 1977. It appeared timely to hold this Symposium for the following reasons: (1) Apart from significant scientific work reported in the literature, progress in other directions between 1972 and 1977 had also been made. For example, the number of food items authorized by governments, with or without restriction, had grown from 19 to 26, and the number of countries accepting one or more irradiated foods for human consumption had increased from 11 to 19. (2) Largely on the basis of the work of the International Project in the Field of Food Irradiation (Karlsruhe), already described at the Bombay Symposium, an international expert committee, jointly convened by FAO, the IAEA and WHO in August-September 1976, had made important statements on the philosophy of wholesomeness studies

    Insects are of value to man in many scientific studies. Microsomal detoxication systems exist in both insects and mammals. In the preliminary investigations it was found that irradiated cocoa beans and white and red kidney beans (Phaseolus spp.) did not significantly change the percentage of egg-hatch in the insects tested. In more detailed investigations food samples that are susceptible to insect spoilage and are representatives of widely consumed human foods were fed to various insect species. The development, sex distortion and reproductivity of the insects were investigated. Cytogenetic aberrations as related to dominant lethality were studied in insects with reasonably clear chromosomal patterns. The meiosis stage was examined, using the squash technique and Aceto-orcein staining. Black beans, Phaseolus spp., irradiated with up to 200 krad of gamma rays did not apparently change the percentage of survival and the sex ratio of the bean weevil, Zabrotes subfasciatus. Dominant lethality in the German cockroach, Blatella germanica, fed on irradiated black beans did not apparently occur when considering the results of cytological investigation and the number of offspring obtained. Dried sardine samples irradiated with up to 400 krad of gamma rays neither apparently affected the survival nor caused sex distortion in the cheese skipper, Piophila casei. This irradiated product apparently did not induce dominant lethality in the German cockroach as tested. Coffee processed from coffee beans that had been irradiated with up to 100 krad of gamma rays did not apparently cause adverse effects on the experimental insects. (author)

    Post-harvest losses due to sprouting, insect infestation and spoilage by microorganisms is a serious problem in many countries and commonly aggravates the problem of food shortages. In addition, many developing countries also depend largely on agricultural produce, such as grain, tuber and tropical fruit, as major export crops to earn foreign exchange. The use of ionizing radiation as an effective means of disinfecting and/or prolonging the self-life of several food products has been well documented in a number of developing countries. The World health organization (WHO) encourages its Member States to consider all measures to eliminate or reduce food borne pathogens in food and improve their supplies of safe and nutritious food. In regard to its contribution to food safety, food irradiation may be one of the most significant contributions to public health to be made by food science and technology since the introduction of pasteurization. Because the promotion of a safe, nutritious and adequate food supply is an essential component of its primary health care strategy, WHO is concerned that the unwarranted rejection or limitation of this process may endanger public health and deprive consumers of the choice of foods processed for safety.

    The design and the operation of a food irradiator is a complex process. Inevitably it results in a compromise between the Cobalt-60 utilization efficiency and the desired flexibility in operating parameters and costs. It is therefore essential that the operating scenario of an irradiation facility is established in detail so that costing can result in an optimal final product. It is also clear that a given irradiation facility may not require the ultimate flexibility in processing parameters as described above. In order to generate accurate cost/Kg estimates for food irradiation applications, it is essential that each case be examined in the context of a precise scenario. This examination is best done through the collaborative efforts of the intended operator and the equipment supplier. By correlating known capital costs with known annual operating costs and estimated annual throughputs, a proper comparison of relative irradiation costs per kilogram of product can be achieved. This in turn, facilitates the choice of optimum plant design and capacity. (author). 4 refs

    1998-01-01

    For years most consumers have expressed less concern about food irradiation than other food processing technologies. Attitude studies have demonstrated that when given science-based information, from 60% to 90% of consumers prefer the advantages irradiation processing provides. When information is accompanied by samples, acceptance may increase to 99%. Information on irradiation should include product benefits, safety and wholesomeness, address environmental safety issues, and include endorsements by recognized health authorities. Educational and marketing programs should now be directed toward retailers and processors. Given the opportunity, consumers will buy high quality, safety-enhanced irradiated food

    This study is to investigate ways to improve the marketability of irradiated food materials, through examining reports on toxicological safety and public acceptance of irradiated food materials. Many studies have reaffirmed the mutagenic, genotoxicological, microbiological, and nutritional safety of food irradiation, and consider it an important tool to reduce loss of food due to spoilage and pests. Although food irradiation could provide an opportunity to replace certain pesticides and food additives, there is ambivalence among consumers on whether or not the technology provides a real benefit. An easy and inexpensive tool to identify irradiation trace residue in foods, public trust building in industry through educating consumers with the benefit and uses of irradiation process are thought to be key elements for a successful market for irradiated food. Gamma irradiation at 50 kGy was applied to food materials for institutional food-service to evaluate their possible genotoxicity. The genotoxicity of 12 kinds of food materials irradiated at 50 kGy for institutional food-service was evaluated by Salmonella typhimurium reversion assay, chromosomal aberration test and in vivo micronucleus assay. The results of bacterial reversion assay with S. typhimurium TA98, TA100, TA1535 and TA1537 were negative in the 12 kinds of food materials irradiated at 50 kGy. No mutagenicity was detected in the assay with and without metabolic activation. In chromosomal aberration tests with CHL cells and in vivo mouse micronucleus assay, no significant difference in the incidences of chromosomal aberration and micronuclei was observed between non-irradiated and 50 kGy-irradiated food materials. These results indicate that food materials irradiated at 50 kGy for institutional food-service did not show any genotoxic effects under these experimental conditions.

    The hydrocarbon method for the detection of irradiated foods is now recognized as the international technique. This method is based on radiolysis of fatty acids in food to give hydrocarbons. In order to expand this technique's application, ten foods (butter, cheese, chicken, pork, beef, tuna, dry shrimp, avocado, papaya, and mango) were irradiated in the range from 0.5 to 10 kGy and the hydrocarbons in them were detected. Recoveries of the hydrocarbons from most foods were acceptable (38-128%). Some hydrocarbons were found in non-irradiated foods, particularly, in butter, cheese, tuna, and shrimp. Seven irradiated foods, butter, cheese, chicken, beef, pork, tuna, dry shrimp, and avocado were detectable at their practical doses by measuring the appropriate marker hydrocarbons. In most case, marker hydrocarbon will be 1,7-hexadecadiene. However, the marker hydrocarbons produced only in irradiated foods varied from food to food; therefore, it is necessary to check a specific irradiated food for marker hydrocarbons. On the other hand, two irradiated foods (papaya and mango which were irradiated at their practical doses) were difficult to distinguish from non-irradiated foods using this method. (author)

    The present state of studies on feasibility and wholesomeness of irradiated food is presented. Irradiation projects were realized of potatoes, onions, wheat, Vienna sausages, fish-paste products, and mandarine oranges. Mutagenecity tests with Salmonella or E. coli, chromosome aberration tests, dominant lethal tests, fibroblasts and micronucleus tests, and toxicity tests performed in amimals fed with irradiated food showed no positive results

  2. Current status and regulation of food irradiation

    1987-01-01

    It is estimated by the Food and Agricultural Organization (FAO) of the United Nations that 25 to 35 percent of world food production is lost through natural causes such a pests, microbes, and insects. In the ASEAN countries alone, postharvest losses of cereals are estimated at 30 percent, fruits and vegetables at 20 to 40 percent, and up to 50 percent for fish. Some products in Africa suffer postharvest losses as high as 50 percent. One of the best responses to the problem of world hunger is preservation of what has already been grown. If postharvest losses worldwide could be minimized, food supply gains could be made without allocation of additional resources. The problems of food production, processing and storage require a continuing search for effective, technically and economically feasible alternative methods of food preservation. Food irradiation is not a panacea for this problem, however. Alone, it cannot change conditions or solve the problems of world hunger, but it can become a factor in the improvement of conditions where improved human nutrition is an immediate need. Food irradiation has progressed steadily over the past 40 years in terms of research, development, and legislative or regulatory activities

    Losses of agricultural produce in Thailand are due to the hot climate accelerating the ripening of fruits and sprouting of vegetables, spoilage microorganisms, pathogenic microorganisms, and insect infestation. Losses amount to as much as 30%. Onion, garlic and potato which have a short shelf-life, for instance, cannot be stored long enough for off-season domestic consumption. The annual production and domestic consumption of onion in Thailand is approximately 50,000 and 30,000 tons respectively. However, about 50% of the harvest is discarded during storage because of rotting and sprouting. Fresh onion can be stored for only a few months under tropical conditions. Therefore during the scarce season of 1982, Thailand had to import 4,760 tons of onion at a cost of 56 million baht. Other major problems for fruit are short shelf-life and insect infestation. Food items for export may meet with rejection by importing countries due to insect infestation and microbial contamination. This can mean considerable economic loss. In order to solve these problems, the government of Thailand is interested in setting up a multi-purpose agricultural pilot plant demonstration facility for government-industry-consumer benefit. Since 1963, the Office of Atomic Energy for Peace (OAEP) has been responsible for carrying out research and development in food irradiation in the areas of extending shelf-life, insect disinfestation, radicidation, and inhibition of sprouting in food and agricultural produce. There are many well-trained scientists able to assist in the commercialization of food irradiation. The multi-purpose agricultural pilot plant demonstration facility in this project will be operated by the staff of OAEP. The service will be available for irradiation of eight selected food items, initially for 6,084 operating hours. These are onion, potato, and garlic at 6,000, 2,000, 6,000 tons respectively; salted and dried fish at 1,000 and mungbeans at 3,000 tons; fermented pork, Vietnam

  5. Irradiated food: validity of extrapolating wholesomeness data

    Criteria are considered for validly extrapolating the conclusions reached on the wholesomeness of an irradiated food receiving high doses to the same food receiving a lower dose. A consideration first is made of the possible chemical mechanisms that could give rise to different functional dependences of radiolytic products on dose. It is shown that such products should increase linearly with dose and the ratio of products should be constant throughout the dose range considered. The assumption, generally accepted in pharmacology, then is made that if any adverse effects related to the food are discerned in the test animals, then the intensity of these effects would increase with the concentration of radiolytic products in the food. Lastly, the need to compare data from animal studies with foods irradiated to several doses against chemical evidence obtained over a comparable dose range is considered. It is concluded that if the products depend linearly on dose and if feeding studies indicate no adverse effects, then an extrapolation to lower doses is clearly valid. This approach is illustrated for irradiated codfish. The formation of selected volatile products in samples receiving between 0.1 and 3 Mrads was examined, and their concentrations were found to increase linearly at least up to 1 Mrad. These data were compared with results from animal feeding studies establishing the wholesomeness of codfish and haddock irradiated to 0.2, 0.6 and 2.8 Mrads. It is stated, therefore, that if ocean fish, currently under consideration for onboard processing, were irradiated to 0.1 Mrad, it would be correspondingly wholesome

    The International Conference on the Acceptance, Control of, and Trade in Irradiated Food, jointly sponsored by FAO, IAEA, WHO and ITC-UNCTAD/GATT, Geneva, Switzerland, December 1988, recognized that (1) food irradiation has the potential to reduce the incidence of foodborne diseases; (2) food irradiation can reduce post-harvest food losses and make available a larger quantity and a wider variety of foodstuffs for consumers - It can also be an effective quarantine treatment for certain food and thus contribute to international trade; (3) international trade in irradiated foods would be facilitated by harmonization of national procedures based on internationally recognized standards for the control of food irradiation. The ''International Document on Food Irradiation'' adopted by consensus at the Conference is included in this issue, which also contains excerpts of the 5th Annual Meeting of the International Consultative Group on Food Irradiation (ICGFI), convened in Vienna, September 1988, and reports of two co-ordinated meetings, the second Research Co-ordination Meeting on the Use of Irradiation as a Quarantine Treatment of Food and Agricultural Commodities, and the Second Co-ordination Meeting on Food Irradiation Programme for Developing Countries in Middle East and Europe. 3 tabs

    Irradiation of foods drew attention mostly in 1960s for disinfestation of food grains, spices and sprout inhibition in mainly potato and onion. γ-irradiation at 0.25 to 1 kGy dosage levels are usually used for irradiating grains, legumes, spices and sprout-prone vegetables. Irradiation of foods with in permissible dosage levels of 0.25 to 5 kGy is usually considered fairly safe from human consumption point of view not withstanding usual health concerns about its usage in foods. Irradiation of foods, in mostly solid or semi-solid form, at 5 kGy levels of γ-irradiation can achieve radicidation or, radiation equivalent of pasteurization and, if γ-irradiation is used at 10 kGy, it can achieve radappertization or, radiation equivalent of thermal commercial sterilization. However, the food industry uses γ-irradiation at 0.25 to 2 kGy only for mostly disinfestation of food grains/legumes, spices, sprout inhibition in potato and onion and, for surface sanitation of frozen fish, poultry and meat. Exposure to irradiation creates free radicals in foods that are capable of destroying some of the spoilage and pathogenic microflora but the same can also damage vitamins and enzymes besides creating some new harmful new chemical species, called unique radiolytic products (URPs), by combining with certain chemicals that a food may be laced with (like pesticides/fungicides). Exposure to high-energy electron beams are also known to create deleterious biological effects which may even lead to detection of trace amounts of radioactivity in the food. Some possible causes delineated for such harmful biological effects of irradiation include: irradiation induced vitamin deficiencies, the inactivity of enzymes in the foods, DNA damage and toxic radiolytic products in the foods. Irradiation, a non-thermal food preservation technique, has a role in salvaging enormous post harvest losses (25-30%) in developing economies to increase the per capita availability of foods.

  8. Irradiated food for immunocompromised people

    Immune-compromise is a condition in which the natural defenses against diseases are dimished; several situations can be cited as examples, including mis nourishment, pregnancy, young and old age. This enhances the probability of suffering microbial diseases, caused by food borne pathogens. Traditionally, immune-suppressed patients in hospitals were isolated from the environment, being their food sterilized by different treatments, including irradiation. At present the medical opinion differs from this approach due to the costs and specialized requirements, uncertainties about the clinical benefits, and psychological convenience. So, the tendency nowadays seems to move, when the patient's condition allows it, from 'sterile diets' to 'low microbe diets' (or 'clean diets'). At the National Atomic Energy Commission, Argentina, under Coordinated Research Programmes of the Food and Environmental Preservation Section, International Atomic Energy Agency, in which 14 countries participated, treatments at pasteurizing doses were studied to widen the meals availability for vulnerable persons, to include some products usually considered as 'high risk' , but nutritionally or psychologically adequate. In a first experience, nutritionists working at the corresponding Service in a Buenos Aires hospital elaborated diets suitable for patients with different immune-compromise degrees, and advised on the interesting meal types to be studied. In a second experience, advanced nutrition students of the Entre Rios University performed a sensory evaluation in which 44 immune- compromised patients at the Jose de San Martin Clinical School Hospital, Buenos Aires, tasted a whole irradiated lunch composed of meals usually forbidden due to high microbial risk, though highly desired. The patients evaluated this lunch with high scores and showed enthusiastic towards the irradiation treatment. This preservation treatment could not only be useful to supply hospitals but also supermarkets. (author)

    Despite the poverty in the world, part of all food produced in the world is wasted. The contrast of high food production in the world with hunger, food insecurity and food waste points to the need for combined action and the use of technologies as a solution to combat and eradicate hunger and food waste. Food banks have sprung up worldwide receiving food surpluses and passing on to the needy. These have been encouraged by the ONU - United Nations Organization, however, the lack of quality assurance of these foods already in the food bank has restricted the desired shipment. In this sense, ionizing radiation applied in food brought many positive results, such as increased validity and control insect infestation. So, the aim of this study was to initiate a partnership between irradiation and the food bank through the development of a questionnaire to evaluate the knowledge and acceptance of individuals in the food bank in Brazil. In addition, this study aimed to standardize a basis questionnaire for future research assessment of irradiated foods and disseminate irradiated food. For the construction of the questionnaire as a measuring instrument, a comprehensive and rigorous literature review was made. The questionnaire as a measurement instrument was submitted to the research ethics committee and approved. As a result, the questionnaire has three parts, personal issues, assertive issues and questions of multiple choices and finally an informative question with video. The questionnaire was applied in Ceagesp food bank in the biggest center of food in Brazil. (author)

    The British government has approved food irradiation in Britain on a much wider scale than has taken place previously. The implications for one of the companies currently offering a gamma irradiation service are explored. Irradiation is by a large Cobalt 60 source. Currently the customers are medical, cosmetic and packaging firms. It does not yet have the facilities necessary for large-scale food irradiation, nor does it expect a huge demand for food irradiation as customer resistance is strong. However some dry spices and herbs may be treated next year. (UK)

    Ionising radiation is fatal to all known life forms given sufficient exposure in terms of dose and duration. This property has been used beneficially to sterilise a range of materials, particularly medical products where the removal of all contaminating organisms is deemed essential. Irradiation has long been used to sterilise food for consumption by certain categories of patients. The method is attractive because all potentially contaminating organisms can be removed by one simple treatment. Irradiation also slows down or stops certain processes such as sprouting. There are, however, disadvantages to irradiating food. It is not only DNA that is affected as alterations in lipid and protein components of the food may lead to a loss of quality. Although irradiation will kill bacteria it will probably not affect any toxin produced by those bacteria prior to treatment. Irradiation achieves its effects by damaging molecules, particularly nucleic acids. Consequently, if any of the damage to nucleic acids could be shown to by by a process unique to irradiation, and the products of this unique process could be measured, then there is the basis for a detection system. Furthermore, if the damage could be shown to be proportional to the dose of radiation received then the dose could also be quantified. Legislation, therefore, requires that assays be developed for use in different countries, those which totally ban irradiated food, those which require irradiated food to be labelled and those which have selective laws relating to specific foods and specific levels of irradiation.

  1. Round-table discussion on food irradiation

    1973-01-01

    The possibilities of using radiation for food preservation as a way of alleviating the food deficiency problem in a large part of the world has been studied for some 20 years. Since the idea was recognized as a viable one, scientists had to develop it along three levels: firstly, the technological problems and economic viability had to be faced; at the same time tests had to be initiated to prove the wholesomeness of the irradiated foodstuffs, and then public acceptance and confidence in the end product had to be established. Work is proceeding along these three lines and in some cases, success has been won on all fronts. In others, it is continuing. As a FLASHBACK to the situation TWO YEARS AGO, we thought it interesting to reprint excerpts from a round-table discussion at which scientists from five countries sat down to discuss the pros and cons of food irradiation. ost at the gathering was Dr. Rocco Basson, Director of Chemistry at Pelindaba, South Africa, and the man responsible for directing radiation processing in that country. With him were Dr. Lapidot, Head of the Radiation and Engineering and Processing Section of the Israel Atomic Energy Commission at Soreq; Dr. Saint-Lebe of the Radioagronomy Service, French Atomic Energy Commission, at Cadarache; Dr. Ulmann, then Director of the Food Irradiation Pilot Plant at Wageningen in Holland; and Mr. Roy Hickman, leader of the International Project in the Field of Irradiation, sponsored by the FAO, IAEA and the OECD Nuclear Energy Agency, centred at Karlsruhe in Germany.

  2. Irradiation pilot plants and experimental facilities available for food preservation

    International Nuclear Information System (INIS)

    1975-01-01

    With the ever-increasing world food crisis mankind has to face today, the prevention of spoilage of perishable food is gaining in momentum. The World Food Conference (Rome, November 1974) of the United Nations clearly recognized the importance of food preservation and urged action in this field. Irradiation is one of the recently discovered methods to preserve food. Its practical introduction largely depends on three main factors: (a) proof of the safety for human consumption of the irradiated product, (b) technological feasibility and (c) economic competitiveness of the process. As data on safety for consumption ('wholesomeness') continue to become available, the number of countries authorizing the irradiation of certain food items is growing (present total: 17 countries), and the same is true for the number of licensed irradiated commodities (total: 23). Under these conditions, testing of the technological and economic feasibility of food irradiation is a matter of increasing importance. Economic feasibility of any industrial operation can only be studied in larger-scale experiments. Thus, they can only be performed with radiation sources larger than those found in laboratories, i.e. in pilot irradiators, capable of handling from a few hundred to a few thousand kilograms of material within a short period of time. The Food Preservation Section of the Joint FAO/IAEA Division of Atomic Energy in Food and Agriculture has attempted to collect data on the availability, for food preservation, of suitable irradiators in Member States

    The applications of ionizing radiation for the preservation of food and agricultural products by delaying ripening, destruction of insect pests and pathogenic microorganisms have shown great promise in the country. For more than 30 years, the Philippine Nuclear Research Institute (PNRI) in collaboration with other government and private sectors, has undertaken research and development studies and pilot and semi-commercial scale irradiation of foods. Some of the foods found to be benefit from the use of irradiation technology are mangoes and papayas for disinfestations and delay ripening; onions and garlic for inhibition of sprouting; spices and dehydrated products for reduction of microbial growth and rice and corn for insect and shelf-life extension. Two regulations approved by the Department of Health and the Bureau of Plant Industry are in place creating an enabling environment for food safety and trade of irradiated food. The conduct of awareness program in various parts of the country provided knowledge and information about the food irradiation technology. The Institute has been part of the international projects (IAEA and USDA) on the use of irradiation for sanity and phytosanitary treatment of food. The projects not only established the potential benefits of food irradiation for socio-economic development of the country but also built considerable capacity to properly treat foods. Some of the recent developments in the area of food irradiation include publication of Philippine National Standard (PNS) on Food Irradiation: Code of Good Irradiation Practices which will serve as a guide for stakeholders to irradiate food, a newly-established Electron Beam Facility to demonstrate the potential use of EB and a feasibility study of putting-up a commercial irradiation facility in the country.

    1999-01-01

    Studies performed on behalf of the International Project on Food Irradiation in the period from 1971 until 1980 resulted in the concluding statement that ''.the irradiation of any food commodity up to an overall average dose of 10 kGy presents no toxicological hazard; hence, toxicological testing of foods so treated is no longer required.'' Since then, licenses for food irradiation have been restricted to this maximum dose in any country applying this technology. Further testing programmes have been carried out investigating the wholesomeness or hazards of high-dose irradiation, but there has been little demand so far by the food industry for licensing of high-dose irradiation, as there is only a small range of products whose irradiation at higher doses offers advantages for given, intended use. These include eg. spices, dried herbs, meat products in flexible pouch packagings for astronauts, or patients with immune deficiencies. (orig./CB) [de

    In 2008, Japan Atomic Energy Commission of Cabinet Office performed the study of current status of food irradiation in the world. The results showed that the total quantity of irradiated foods in 2005 was 405,000 tons. Seven main countries for food irradiation were China, USA, Ukraine, Brazil, South Africa, Vietnam and Japan. In Japan, only the potato irradiation for sprout inhibition is continued more than 35 years since 1974 but the quantity is decreasing. On the other hand, the food irradiation of Vietnam has been developed rapidly in a short time to export the frozen seafood and fruit. This paper shows the status of food irradiation in Vietnam and Japan, and the progress in both countries after 2005. (author)

    1988-01-01

    Two arguments are being used by the opponents of food irradiation. One is that the process is hazardous to both plant operators and members of the public who live nearby. The second is that the irradiation process harms the eventual consumers of the food from either induced radiolytic products or substantially reduced nutritional loss and vitamin loss. This paper argues that whether or not the second point is valid, the process itself is inherently safe and does not present any untoward radiological hazard

    This survey was conducted to determine the level of understanding on radiation and irradiated food products amongst students during an exhibition in conjunction with Nuclear Malaysia Innovation Day 2008, on 16-18 July 2008 at Dewan Tun Dr. Ismail, Malaysian Nuclear Agency. Data were collected from 180 respondents comprising students from various schools visiting the exhibition. The results revealed that 55.56 % of the respondents knew of radiation and 81.11 % agreed that food could be irradiated. However, 53.33 % respondents misunderstood that there was presence of radioactivity in the food after irradiation. The results also showed that respondents knew that various foods can be irradiated and the type of radiation used in irradiation of food products. This survey indicates more aggressive work must be done to educate and introduce the public the application of nuclear technology in modern life, including in food preservation. (Author)

  10. Regulations relating to trading of irradiated food in Europe Countries

    Ehlermann, D.

    1997-01-01

    Only recently, the European Union has prepared a new draft of a Directive to harmonize the food laws of the 15 member states with regard to food irradiation. At present 3 members have not regulated food irradiation, 4 other members have a total ban, the remaining 8 members have widely varying clearances. Members of the European Economic Area (zone of associated European states) will have to adopt such a Directive once in force. It is expected that the European Parliament soon will pass the Directive which only provides for spices irradiated up to 10 kGy. However, for a transition period of five years it will allow members states to continue with national regulations. The European Single Market should provide for free trade in any item legally marketed in any member state and, hence, for marketing irradiated food to member states which have not yet a clearance or not for that particular food. Other European countries, i e the former members of the COMECON, have widely varying clearances; some are still in the process of renewing their respective juridical systems, and food irradiation is not a priority. For such reasons, imports of irradiated food from such countries into the E U are difficult and diverse. The main factor causing a lack of commercial application of food irradiation and of inter-E U trade is the low interest of food industry and food trade. Consumer acceptance is of second consideration. The European Directive will fulfill the most prominent demand of consumer organization, the labelling of irradiated food with no exception, even for the most minute ingredient. There is no reliable information about quantities of irradiated food in Europe; for official statistics it is considered not different from other food. (Author)

  12. Why the concern about irradiation as a food preservation technique?

    International Nuclear Information System (INIS)

    Anon

    2001-01-01

    Full text: Irradiation is a food preservation process that like the more traditional and alternative methods is intended to keep food safe to eat by delaying the natural decomposition processes that result from bacterial action. Preservation of foods by irradiation, although still not available in Australia, is readily accepted in some 44 countries, including France. This project is set up to examine if a sample of fresh fruits and vegetables, when irradiated to the recommended 'preservation' dose level, becomes 'radioactive'. By placing the 'irradiated' sample, together with an identical 'control' sample of the same fresh fruit and vegetables, in an x-radiography cassette in a shielded 'cave', differences in film 'blackening' over the exposure period would indicate relative radioactivity from within the respective samples. Also, using simultaneous daily photographs of both the 'irradiated' and non-irradiated 'control' samples, the delay of onset of visible decay of both can be determined

    The food irradiation has the history of more than 60 years in its development. However, its commercial application has not been promoted well in Japan even though the safety of irradiated foods was confirmed. Recently, relevant authorities in 52 countries have given clearance to many commodities, and irradiated foods are commercially distributed in USA and EU countries. The international situation makes some unavoidable circumstances which can not close the commercialization of food irradiation in Japan. The present report contains the basis and application of food irradiation, and history of development in the World and Japan. Moreover, the safety of irradiated foods are demonstrated from many evidences of researches in animal feeding tests, in analysis of radiolytic products, in nutritional evaluations and in microbiological studies of irradiated foods. Especially, it makes obvious from the results of many researches that unique radiolytic products can not be produced by irradiation of foods. Because main radiation effects are induced by oxidation degradation of food components as similar to natural oxidation by heating or UV light. Radiation engineering for commercial process and identification methods of irradiated foods are also presented. (author)

    The use of irradiation to preserve food has the potential to significantly enhance our capacity to maximize the quality and quantity of the food we consume. In a world in which distribution of food occurs across continents and in which malnourished populations are in dire need of basic food products, any safe, effective, and efficient means of preserving food is more than welcome. Irradiation, as a method for food preservation, has been studied for more than 30 years. This discussion focuses on this most recent method for the preservation of food with particular emphasis on its effects on the safety, nutritive, and aesthetic values of the food preserved by irradiation. The use of ionizing radiation as a method to preserve foods is one that has been demonstrated to be effective for a variety of food classes. Irradiation offers a means to decontaminate, disinfest, and retard the spoilage of the food supply. At the same time, it appears that the wholesomeness of these food products is maintained. Nutritive value can be sustained by use of effective doses of radiation. Concerns over the safety of irradiated food are rooted in questions regarding the potential induction of radioactivity, harmful radiolytic products, and pathogenic radiation-resistant or mutant strains of microorganisms. Research findings have allayed concerns over safety. However, more research is necessary to conclusively resolve these safety issues. Food irradiation is a promising technology that has and will contribute to our ability to feed the people of this world. This technology is but one of many available ways to preserve our greatest natural resource, the food supply. Enhancement of the ability to preserve food by irradiation will facilitate the distribution of food from fertile developed regions to the malnourished peoples of underdeveloped countries. 21 references

    Information is unanimously recognised as the key to a wide acceptance of irradiated food. A case by case approach is necessary as the context may vary greatly from one country to another. Some actions that took place in the particular French situation are reported. The various targets are addressed and the theoretical product adoption process is described. In spite of several encouraging facts, it appears that a lot has yet to be done before any reliable conclusion on the acceptation or rejection of the process can be reached

    This paper reviews researches, commentaries, and conference and public records of food irradiation, published mainly during the period 1987-1989, focusing on the current conditions of food irradiation that may pose not only scientific or technologic problems but also political issues or consumerism. Approximately 50 kinds of food, although not enough to fill economic benefit, are now permitted for food irradiation in the world. Consumerism is pointed out as the major factor that precludes the feasibility of food irradiation in the world. In the United States, irradiation is feasible only for spices. Food irradiation has already been feasible in France, Hollands, Belgium, and the Soviet Union; has under consideration in the Great Britain, and has been rejected in the West Germany. Although the feasibility of food irradiation is projected to increase gradually in the future, commercial success or failure depends on the final selection of consumers. In this respect, the role of education and public information are stressed. Meat radicidation and recent progress in the method for detecting irradiated food are referred to. (N.K.) 128 refs.

    This paper reviews the status and acceptance of food irradiation worldwide, focusing on Europe and the United States. Today no less than 38 countries including the USA and 14 European countries, have approved the irradiation of food. Across Europe there is a very wide variation, with a variety of foods being irradiated and eaten in Belgium and France but a total ban on food irradiation in Germany. Progress towards a directive harmonising the position across all countries in the European Union is slow. In the USA there is a growing awareness of the advantages of using food irradiation to combat the increasing risk of the food-borne diseases, and media coverage and consumer attitudes are considerably more favourable than previously. The use of irradiation instead of pesticides for spice treatment is gaining acceptance within the North American spice industry and the NA meat industry is recognising the potential of food irradiation as one way of meeting its obligations under the new HACCP regulations. Food irradiation is also being seriously considered as an alternative to the use of methyl bromide for quarantine treatment of fruit and vegetables. The establishment of the World Trade Organisation in 1995 to enforce various agreements concluded during the GATT Uruguay Round is expected to impact trade liberalisation. In particular the agreements pertaining to the Application of Sanitary and Phytosanitary Measures (SPS) and on Technical Barriers to Trade (TBT) have particular reference to track in irradiated food. In this respect, it is particularly important for potential training partners (food producing countries) to ensure that they have domestic approvals in place for any irradiated foods they provide to western countries.

    Food contamination corresponds to the undesired presence of radioactive products in food, while irradiation is a process to which food can be deliberately submitted to improve its preservation or hygiene. This publication explains this difference. It describes the process, physical effects and health impacts of radioactive contamination of food. It briefly describes irradiation or ionisation processes, their objectives, doses of ionising radiations used on food products, undesired and harmful effects. It also indicates food products concerned by these irradiation processes, and the associated legal framework, evokes the lack of information of consumers regarding such practices, briefly evokes risks associated with irradiation installations, and indicates where these installations are located in France

  9. Economics of gamma irradiation processing

    International Nuclear Information System (INIS)

    Tani, Toshio

    1980-01-01

    The gamma-ray irradiation business started at the Takasaki Laboratory of Japan Atomic Energy Research Institute. The irradiation facilities were constructed thereafter at various sites. The facilities must accept various types of irradiation, and must be constructed as multi-purpose facilities. The cost of irradiation consists of the cost of gamma sources, construction expense, personnel expense, management expense, and bank interest. Most of the expenses are considered to be fixed expense, and the amount of irradiation treatment decides the original costs of work. The relation between the irradiation dose and the construction expense shows the larger facility is more economical. The increase of amount of treatment reduces the original cost. The utilization efficiency becomes important when the amount of treatment and the source intensity exceed some values. The principal subjects of gamma-ray irradiation business are the sterilization of medical tools and foods for aseptic animals, the improvement of quality of plastic goods, and the irradiation of foods. Among them, the most important subject is the sterilization of medical tools. The cost of gamma irradiation per m 3 in still more expensive than that by ethylene oxide gas sterilization. However, the demand of gamma-ray irradiation is increasing. For the improvement of quality of plastic goods, electron irradiation is more favourable than the gamma irradiation. In near future, the economical balance of gamma irradiation can be achieved. (Kato, T.)

    International interest in the industrial use of ionizing radiation as a means of food preservation has increased rapidly following the favourable outcome of many years of intensive research on the health implications of food irradiation. The introduction in the U.S. and elsewhere of legislation restricting the use of chemical additives to foods for both human and animal consumption has contributed to this development. A high priority must be given to coordinating legislation on food irradiation within the European Community if international trade in irradiated foods is to make progress and food losses by spoilage and by insect infestation are to be minimised. Speakers from the United Kigdom, France and Germany describe the legislative and developmental situation in their respective countries. The implication for the Irish food industry is presented by scientists working on food research and development and regulatory aspects in Ireland are also discussed

    Irradiation treatment of food is becoming an increasingly accepted processing option for countries in the Asia Pacific region wishing to meet growing sanitary and phytosanitary requirements in international trade. There remain however, large differences between the regulatory requirements in the countries in this region. This paper gives an outline on existing food irradiation regulations in the separate countries of the Asia Pacific region. New developments such as the recent decision by the Australia New Zealand Food Authority to start assessing applications for food irradiation treatment are discussed. Australia's intention to regulate the export of food treated by irradiation will also be outlined. Details of the decision to harmonise food irradiation regulations by 13 countries in the Asia Pacific region based on conformance with Codex requirements is outlined. The likelihood of other Asia Pacific countries enacting similar harmonisation of their regulations will be examined. Future development such as certification of irradiation as a sanitary treatment for food are discussed. The expected result of these initiatives is a likely increase in irradiated foods traded within the Asia Pacific region

    This study was exploratory in nature, with emphasis on initial purchases and not repeat purchases or long-term loyalties to either irradiated or non-irradiated produce. The investigation involved the actual sale of irradiated and non-irradiated apples to consumers. Limited information about the process was provided, and apples were sold at roadside stands. Prices for the irradiated apples were varied while the price for the non-irradiated apples was held constant. Of these 228 West-Central Missouri shoppers, 101 (44%) bought no irradiated apples, 86 (38%) bought only irradiated apples, and 41 (18%) bought some of both types, Results of probit regressions indicated three significant independent variables. There was an inverse relationship between the price of irradiated apples and the probability of purchasing irradiated apples. There was a positive relationship between the purchasers’ educational level and the probability of purchasing irradiated apples. Predicted probabilities for belonging to categories in probit models were computed. Depending on particular equation specification, correctly placed were approximately 70 percent of the purchasers of the two categories--bought only non-irradiated apples, or bought some of both irradiated and non-irradiated apples or only irradiated apples. This study suggests that consumers may be interested in food irradiation as a possible alternative or supplement to current preservation techniques

  1. Anticipated consumer reaction to irradiated foods

    Young, M.

    1983-01-01

    The reaction on first hearing of food irradiation is horror, revulsion, and disbelief that we could seriously anticipate such a thing. Ignorance coupled with fear of anything to do with the nuclear industry is the reason for such extreme reaction. Before anyone rushes into marketing irradiated foods, a lot of careful preparation must be done. A consumer education program is essential. The consumers must be told why it is proposed to irradiate food, what benefits it will bring to the public. Enough need will have to be demonstrated to overcome the supposed risk factor. Symbol on all irradiated foods must not be used to alert or alarm the consumer but rather as a piece of information. It will be necessary to be ever vigilant, to keep up the diligent training of food irradiators, food handlers and food inspectors. Irradiation is not a substitute for good manufacturing practice. So by using a different name or symbol, irradiated foods will soon be a part of our lives

The effect of food irradiation as a convenience to the consumer is discussed, i.e. the prevention of food deterioration and also the prevention of disease that could be passed on to the consumer by ingestion. On the other hand, the effects that could possibly be created by the application of radiation are also evaluated using toxicological and microbiological considerations. (Auth.)

    The situation regarding food irradiation in France is one of cautious progress, with clearance of specific food items including onions, garlic, shallots, deboned poultry meats and 72 spices. A general clearance for the use of ionizing radiation treatment up to 1 kilogray is under consideration. A most important guiding principle has apparently been accepted in France that no further toxicological studies are required for food irradiation dose levels up to ten kilograys

    The quick development concerning the commercial application of food irradiation in the USA recently resulted in growing marketing of irradiated red meat as well as irradiated fresh and dried fruits. These gamma and electron irradiation technologies require specific dosimetry systems for process control. The new version of the Sunna dosimeter has been characterized in gamma, electron and bremsstrahlung radiation fields by measuring the optically stimulated luminescence (osl) at 530 nm both below and above 1 kGy, i.e. for disinfestation and for meat irradiation purposes. No humidity and no significant dose rate effect on the green osl signal was observed. The temperature coefficient was determined from 0 deg. C up to about 40 deg. C and to stabilize the osl signal after irradiation a heat treatment method was introduced. Based on these investigations the Sunna 'gamma' film is a suitable candidate for dose control below and above 1 kGy for food irradiation technologies

    Proceedings of an International Conference on the Acceptance, Control of and Trade in Irradiated Food jointly organized by the Food and Agriculture Organization of the United Nations, the World Health Organization, the International Atomic Energy Agency and the International Trade Centre-UNCTAD/GATT and held in Geneva, 12-16 December 1988. The Conference was prompted by the lack of acceptance by some governments, which do not see a need for the application of food irradiation technology in their own countries, and as a consequence may hamper its use in other countries where its application could significantly improve consumer health and nutrition, as well as national economic and trading potential. This publication contains discussions on the key issues of the wholesomeness of irradiated food, the contribution of this technology to public health, food security and international trade, the control of the process to ensure its correct application for consumer protection, and the acceptance of irradiated food by industry and consumers. The proceedings include the International Document on Food Irradiation, highlighting the major issues related to the acceptance of irradiated food by consumers, governmental and intergovernmental activities, the control of the process, and trade. A number of Member States formally expressed their views on this International Document, expressing either endorsement or reservation, and their statements are included in these proceedings.

  8. Irradiation: a safe measure for safer food

    Beef is one of the U.S. food industry's hottest sellers--to the tune of 8 billion pounds a year, according to trade figures. Whether at a fast-food meal, a dinner on the town, or a backyard barbecue, beef is often front and center on America's tables. But in recent years, beef, especially ground beef, has shown a dark side: It can harbor the bacterium E. coli O157:H7, a pathogen that threatens the safety of the domestic food supply. If not properly prepared, beef tainted with E. coli O157:H7 can make people ill, and in rare instances, kill them. In 1993, E. coli O157:H7-contaminated hamburgers sold by a fast-food chain were linked to the deaths of four children and hundreds of illnesses in the Pacific Northwest. In 1997, the potential extent of E. coli O157:H7 contamination came to light when Arkansas-based Hudson Foods Inc. voluntarily recalled 25 million pounds of hamburger suspected of containing E. coli O157:H7. It was the largest recall of meat products in U.S. history. Nationally, E. coli O157:H7 causes about 20,000 illnesses and 500 deaths a year, according to the federal Centers for Disease Control and Prevention. Scientists have only known since 1982 that this form of E. coli causes human illness. To help combat this public health problem, the Food and Drug Administration, in December 1997, approved treating red meat products with a measured dose of radiation. This process, commonly called irradiation, has drawn praise from many food industry and health organizations because it can control E. coli O157:H7 and several other disease-causing microorganisms. As with other regulations governing meat and poultry products, irradiation will be authorized when the U.S. Department of Agriculture completes its implementing regulations. Though irradiation is the latest step toward curbing food-borne illness, the federal government also is implementing other measures, which include developing new technologies and expanding the use of current technologies

    Radiation processing is a highly versatile preservation technique for the food industry. It is a cold treatment which can inhibit sprouting, eliminate insects and food pathogens, extend shelf life, decontaminate raw materials, and pasteurise or sterilise food and packaging materials. Recent developments, such as an International Standard for Irradiated Foods and a Code of Practice for the Operation of Radiation Facilities for the Treatment of Foods, are expected to stimulate and facilitate trade in radiation processed foods. These developments and prospects for commercialisation of this new technology in Australia are discussed

    Using radiation to kill bacteria and other pathogens in food is called food irradiation. Irradiating food kills bacteria and molds that can make people sick. Irradiation does not remove toxins that are already in food. The high energy of the radiation breaks chemical bonds to stop bacteria and other pathogens from multiplying. Irradiation does not make food radioactive.

    The present project was related to the development and establishment of the detection techniques for the safety management of gamma-irradiated food and particularly conducted for the establishment of standard detection method for gamma-irradiated dried spices and raw materials, dried meat and fish powder for processed foods, bean paste powder, red pepper paste powder, soy sauce powder, and starch for flavoring ingredients described in 3, 6, 7 section of Korean Food Standard. Since the approvement of gamma-irradiated food items will be enlarged due to the international tendency for gamma-irradiated food, it was concluded that the establishment of detailed detection methods for each food group is not efficient for the enactment and enforcement of related regulations. For this reason, in order to establish the standard detection method, a detection system for gamma-irradiated food suitable for domestic operation was studied using comparative analysis of domestic and foreign research data classified by items and methods and European Standard as a reference. According to the comparative analyses of domestic and foreign research data and regulations of detection for gamma-irradiated food, it was concluded to be desirable that the optimal detection method should be decided after principal detection tests such as physical, chemical, and biological detection methods are established as standard methods and that the specific descriptions such as pre-treatment of raw materials, test methods, and the evaluation of results should be separately prescribed

  2. Detecting irradiated foods: use of hydroxyl radical biomarkers

    Karam, L.R.; Simic, M.G.

    1988-01-01

    Recent legislation in the United States has increased the probability of using ionizing radiation for preserving food. The possible increased use of food irradiation in this country, in addition to current use of the technique in other countries, makes it important to develop a method whereby the extent of irradiation of foods can be determined. Both opponents and proponents of this particular food-processing technique support postirradiation dosimetry (PID) as a way to measure the extent of changes in irradiated products. To prevent tampering and alteration of the dosimeters, the best postirradiation dosimeters are those that are inherent in the product exposed to the ionizing radiation. Therefore detection of the intermediates and subsequent products arising from the interaction of ionizing radiation with biomolecules in food should be a viable means by which the irradiated status of a food sample can be determined. To be useful as biomarkers, however, the products formed by irradiation must be detectable by routine analytical methods, formed exclusively by ionizing radiation (unless formation from alternate methods can be readily determined), and stable for the duration of the expected shelf life of the food product. In this article Lisa R. Karam and Michael G. Simic of the National Institute of Standards and Technology describe methodology developed to identify the irradiated status of foods using hydroxyl radical biomarkers

    Research on food irradiation in Brazil started in 1968 at the Center of Nuclear Energy for Agriculture (CENA), Piracicaba, Sao Paulo. At the Institute of Nuclear and Energy Research (IPEN-CNEN/SP), Sao Paulo, Sao Paulo, research on detection of irradiated foods is in progress. In 1973, the Brazilian government established a regulation about food irradiation. Nowadays, the products authorized to be irradiated are: rice, poultry, fish and fish products, potatoes, onions, avocados, persimmons, pineapples, wheat flour, maize, beans, spices, tomatoes, guavas, oranges, lemons, strawberries, mangoes, melons and papayas. The other recommended products to be approved in the future are: acerolas, apples, beans (dose > 1 kGy), beef, blueberries, cherries, cheeses, coffee, figs, fresh guaranas, garlics, grapefruits, grapes, mushrooms, nuts and pork. Today, there is only one commercial facility for irradiation services in the country, the Empresa Brasileira de Radiacoes Ltda. (EMBRARAD). This company operates a Nordion JS-7500 irradiator, with a present activity of about 1,000 kCi, designed for sterilizing medical devices. It also irradiates spices, dried foods, gemstones, cosmetics, wood and raw materials for pharmaceuticals. The plant operates 24 hours a day and the spices and dried foods represent 15% of the business. Powder of guarana seeds is irradiated also for exportation. There are two other commercial facilities for radiation sterilization in Brazil, operating exclusively for their own production. (J.P.N.)

    Economic and social factors as cost, availability and food habits usually influence the consumer's choice. Nowadays other factors like legislation, rising of meals eaten out-of-home and the application of new technologies have been affected the shopping decision. In this direction it is necessary to have more explanations about food irradiation as a method to conserve food. Its commercial use has been slow because most of the consumers misunderstands or has wrong belief about this technique. In such a manner, this work aimed at realizing a survey of knowledge and acceptance level of food irradiation in Belo Horizonte (MG), Brazil, and also to elucidate its real meaning to consumers. A total of 218 people were interviewed and the results showed that 59.6% of them have not known that irradiation is a method to preserve food, thus they have no idea if they consume or not this kind of food. About 16% believe that irradiated food means the same of radioactive food. Besides that, 89% of people interviewed could become consumers of this product if they know that irradiation raises the food safety. (author)

  5. Food irradiation combined with refrigeration in food industrial plants

    Food irradiation and refrigeration are both physical treatments used for food preservation. The complementarity of their effects on food is the best reason for their combination. Irradiation is essentially used for disinfestation and refrigeration to protect food against non microbial degradations. Refrigeration and irradiation could be combined for shelf life extension of fresh fruits and vegetables or reduction of microflora in animal products, without loss of quality. Freezing must be combined with ionizing treatments if high doses are necessary as it is the case with destruction of pathogens in meat or food sterilization. Some examples of combination of refrigeration and irradiation are routinely applied in some industrial plants in France but it is expected that more and more combined treatments will be used thanks to research

    The foods availability is a worldwide problem at present, it looks two paradoxical aspects at first appearance. The malnutrition grade and the great losses by rottenness after the harvest time. An alternative to reduce these losses is the use of modern technologies such as food irradiation, which is a recognized process as like as secure and efficient how a conservation process by the FAO, the WHO and the Codex Alimentarius Commission. At present this process is accepted in 40 countries. Since 1986 the National Institute of Nuclear Research in Mexico offers irradiation services to the dried foods enterprises. This work contains magistral conferences dictated by international experts, reflecting the situation of this technology at the present time, the consumer position about the acceptance of irradiated foods, as well as regulations and standards applied in different continents. In the process part there are the installations would be required and the control to carry out. (Author)

    Preservation of food by gamma radiation is technically feasible and economically viable under conditions existing in Pakistan. To educate the consumers, programme for dissemination of information regarding food irradiation was implemented to educate the consumers. Test marketing of irradiated products was carried out for 5-6 years and more than 8 tons of irradiated vegetables were sold to consumers who were briefed about the advantages of radiation technology. A number of condiments including pepper and chillies were irradiated on a large scale (more than 10 tons) at the Pakistan Radiation Service (PARAS) during the years 1996-1998. Comprehensive Harmonised food irradiation regulations, covering all foods in seven classes, were approved in 1996. The charges for irradiating various food commodities ranged from US$19.71/ton potatoes (0.10 kGy) to US$38.32/ton for spices (10.0 kGy). Once the techno-economic feasibility is demonstrated, huge post-harvest losses of different food commodities can be avoided. This will make the country not only self-sufficient in food, but with enough surplus for export. (author)

    2007-01-01

    A brief history of food processes using irradiation is presented with focusing on such specific problems as possible induction of radioactivity by using high-energy X-rays or electron beams and possible formation of mutants or nutritive breakdown of the food. The basis of the argument is mainly the researches carried out in 1960's in USA and 1970's in UK and France, and also Food and Drug Administration (FDA) results on evaluation of wholesomeness of irradiated food using animal breeding during 1954 to 1980. An extensive study on safety test as food and qualifying test for nutrition carried out by the international project group (USA, France, West Germany, Netherlands, UK, and Japan) are also included as an important basis. The author concludes that the safety of food irradiation is well confirmed by continuous researches which have been widely done for these 60 years, as have been guaranteed by WHO. (S. Ohno)

    Studies on various aspects of food irradiation have been done in Indonesia since 1968, mainly at the Centre for the Application of Isotopes and Radiation, National Atomic Energy Agency of Indonesia. Three irradiation facilities available at the Centre are gamma cell-220, panoramic batch irradiator, and latex irradiator with the present source capacities of about 1.1, 40, and 163.8 kCi Co-60, respectively. In this paper, the present status of research and development on irradiation is presented, covering (1) spices and medicinal plants, (2) rice, wheat flour and coffee bean, (3) fish and fishery products, (4) animal feed, and (5) ongoing projects including fresh fruits, cacao beans, and cashew nut. The Sub-Committee for the Control of Irradiation of Food and Medical Products, set up in August 1984, has prepared the draft of recommendations regarding the regulation for application of food irradiation in Indonedia and the draft of Regulation for the Control of and Trade in Irradiated Food and Traditional Drug to be issued by the government.

    1992-01-01

    In Korea, the well-integrated research of biological effects of radiation has been launched from the late 1960s. As research activities, the following food items have been dealt with: sprouting foods, fruits, mushrooms, grains, spices or mixed condiments, fish or fishery products, meat or meat products, and fermented foods. The usage of gamma radiation from 60 Co source is now authorized for food irradiation of the following items: potato, onion, garlic, chestnut, mushroom, dried mushroom, dried spices (including red pepper, garlic, black pepper, onion, ginger, and green onion), dried meat, powdered fish and shellfish, soybean paste powder, hot pepper paste powder, soybean sauce powder, and starch. Since the authorization of food irradiation in 1985, consumers' acceptance has been considered the most important. The survey evaluating the basic perception and attitule toward food irradiation revealed the following results. Consumers' awareness of food irradiation was 82%, with significantly higher in radiation workers than the general public (p<0.0001). Seventy-five percent distinguished the contaminated food by radionuclides from irradiated food. In purchasing irradiated foods, 50.9% required more information. The contribution of irradiated foods to wholesomeness was suspicious in 51%, acceptable in 33%, and uncertain in 16%. If information about the benefits of irradiation is provided to consumers, positive response was increased to 60%. The most critical impediment in the commercial application of food irradiation was found to have resulted from the general consumers' slow acceptance; however, consumers' attitude to irradiated food became positive if they understood the safety and advantages of this technology. The most important task is to overcome consumers' psychological resistance and transporting matters of the products to be irradiated. (N.K.)

    1999-04-01

    To identify irradiated foods, studies have been carried out with electron spin resonance (ESR) spectroscopy on bone containing foods, such as chicken, pork, and beef. The intensity of the signal induced in bones increased linearly with irradiation doses in the range of 1.0 kGy to 5.0 kGy, and it was possible to distinguish between samples given low and high doses of irradiation. The signal stability for 6 weeks made them ideal for the quick and easy identification of irradiated meats. The analysis of DNA damage made on single cells by agarose gel electrophoresis (DNA 'comet assay') can be used to detect irradiated food. All the samples irradiated with over 0.3 kGy were identified to detect post-irradiation by the tail length of their comets. Irradiated samples showed comets with long tails, and the tail length of the comets increased with the dose, while unirradiated samples showed no or very short tails. As a result of the above experiment, the DNA 'comet assay' might be applied to the detection of irradiated grains as a simple, low-cost and rapid screening test. When fats are irradiated, hydrocarbons contained one or two fewer carbon atoms are formed from the parent fatty acids. The major hydrocarbons in irradiated beef, pork and chicken were 1,7-hexadecadiene and 8-heptadecene originating from leic acid. 1,7 hexadecadiene was the highest amount in irradiated beef, pork and chicken. Eight kinds of hydrocarbons were identified from irradiated chicken, among which 1,7-hexadecadiene and 8-heptadecen were detected as major compounds. The concentration of radiation-induced hydrocarbons was relatively constant during 16 weeks

  5. Detection of food irradiation - two analytical methods

    International Nuclear Information System (INIS)

    1994-01-01

    This publication summarizes the activities of Nordic countries in the field of detection of irradiated food. The National Food Agency of Denmark has coordinated the project. The two analytical methods investigated were: the gas-chromatographic determination of the hydrocarbon/lipid ratio in irradiated chicken meat, and a bioassay based on microelectrophoresis of DNA from single cells. Also a method for determination of o-tyrosine in the irradiated and non-irradiated chicken meat has been tested. The first method based on radiolytical changes in fatty acids, contained in chicken meat, has been tested and compared in the four Nordic countries. Four major hydrocarbons (C16:2, C16:3, C17:1 and C17:2) have been determined and reasonable agreement was observed between the dose level and hydrocarbons concentration. Results of a bioassay, where strand breaks of DNA are demonstrated by microelectrophoresis of single cells, prove a correlation between the dose levels and the pattern of DNA fragments migration. The hydrocarbon method can be applied to detect other irradiated, fat-containing foods, while the DNA method can be used for some animal and some vegetable foods as well.Both methods allow to determine the fact of food irradiation beyond any doubt, thus making them suitable for food control analysis. The detailed determination protocols are given. (EG)

    1986-01-01

    Food treatment by stream of electrons, X or gamma photons, induces an ionization in the medium whom consequences are very more important for contaminants than for food components. Effects upon insects are spectacular at very low doses of about 0.15 kGy and so it is for microoganisms at doses of some 1 kGy. Products consecutive to this radiolysis are of the same nature that the one induced by thermolysis. Ionizing treatments are the only ones allowing an efficacious sterilization of foods without any cooking. Irradiation plants are yet ready and of two types: large for multiple applications, small for single product. Small gamma irradiators and electron accelerators allow line treatment [fr

    1985-01-01

    The Food Terminal Inc. in Manila, in cooperation with the Philippine Atomic Energy Agency and with funding support from the International Atomic Energy Agency in Vienna has been conducting storage and marketing studies on onions, garlic and mangoes. The objective is to gather loss reduction data and consumer reaction information that can serve as a basis for evaluating the risks and benefits involved in the establishment of a commercial food irradiator in the country. These studies show that irradiation reduces low-temperature storage losses in onions and garlic by 10-40% and post-storage marketing losses at ambient conditions by 16-50% in onions. Post-storage marketing trials not only indicate a significant reduction in losses during shipping and retail sale but a large increase in the marketability of irradiated commodities as measured by the rate of sale of the commodity and the price which it commands during the selling period. No adverse consumer reaction occurred during the sale of irradiated foods labelled as such except for a few comments indicating fear, ignorance and/or curiosity. The importance of irradiation as a substitute quarantine treatment for mangoes and for eliminating Salmonella in frozen foods for export is discussed in relation to the growing importance of these commodities to the Philippines' non-traditional export markets. Other applications of irradiation that could result in a perceptible improvement in the marketability of food commodities in the Philippines are discussed. Marketing studies are invaluable in evaluating the potential benefits of a new technology as food irradiation. In view of this, there is great interest in the completion of a pilot plant for food irradiation by the Philippine Atomic Energy Commission. The design and capacity of this plant are discussed

    Chronic toxicity of irradiated salted and dried mackerel was evaluated by multi-generation rat feeding studies. Salted and dried mackerel samples were irradiated with 200krad, ground and mixed with a standard laboratory animal diet at 28% w/w. Wistar strain rats were used in the experiment and were divided into 3 groups and fed their respective diets, i.e. stock ration, diet containing 28% of non-irradiated salted and dried mackerel and diet containing 28% of irradiated salted and dried mackerel. The test was carried out for 3 generations. The results revealed no significant difference that would impose a hazard attributable to consumption of irradiated salted and dried mackerel with respect to longevity, carcinogenicity, teratogenicity, dominant lethal, reproductive function and biophysiological function in animals tested

    1984-01-01

    Studies were made on the use of irradiation in combination with curing salts to control Salmonella in meat products. Irradiation of meat samples with a dose of 3kGy resulted in 3.6-7.1 log cycle reduction of different strains of Salmonella. Salmonella which survived irradiation treatment appeared to die at a faster rate at 0-2 deg. C and showed retarded growth during storage at 8-10 deg. C as compared to untreated culture subjected to the same conditions. Irradiation at 1kGy and 3-6% NaCl had a strong influence on the reduction of Salmonella in ground meat. The addition of 200mg/kg of NaNO 2 or 200mg/kg NaNO 2 and 3% NaCl into ground meat irradiated with 1kGy and stored either at 0-2 deg. C or 20 deg. C had a synergistic effect on the reduction of Salmonella. Irradiation did not change the overall acceptability of the meat samples. A synergistic effect of irradiation and curing salts on the acceptability of ground meat stored at 0-2 deg. C was observed. However, when the samples were stored at 20 deg. C, no advantage from irradiation could be demonstrated on the shelf-life and acceptability

    In spite of an irradiated food is innocuous for health and that the irradiation process offers great advantages as conservation and hygiene method and it has been recognised by the Agriculture and Health International organizations and although the adequate equipment exists to make this treatment in the majority of countries, an international trade of irradiated foods has not been established and it is that it has to be required that the quality control of the treatment should be regulated by the corresponding authorities and it also should be harmonized with other countries for the commercial interchange. Owing to up to present an identification method of irradiated foods which is validated, the unique quality control for irradiated foods is realized in the irradiation plant, measuring the absorbed dose in products, using dosimetric systems justly calibrated and standardized to be used the adequate for the type of product and dose level which is wanted to be measured for foods mainly for quarantine treatment which is very important to determine that any part of the irradiation system has reached the minimum dose to obtain the technical effect which is desired and that it does not exceed the maximum dose for that the product quality not to be altered.

  16. Analytical detection methods for irradiated foods

    International Nuclear Information System (INIS)

    1991-03-01

    The present publication is a review of scientific literature on the analytical identification of foods treated with ionizing radiation and the quantitative determination of absorbed dose of radiation. Because of the extremely low level of chemical changes resulting from irradiation or because of the lack of specificity to irradiation of any chemical changes, a few methods of quantitative determination of absorbed dose have shown promise until now. On the other hand, the present review has identified several possible methods, which could be used, following further research and testing, for the identification of irradiated foods. An IAEA Co-ordinated Research Programme on Analytical Detection Methods for Irradiation Treatment of Food ('ADMIT'), established in 1990, is currently investigating many of the methods cited in the present document.

    MacPhee, D.; Hall, W.

    1988-01-01

    A series of studies undertaken at the National Institute of Nutrition (NIN) in India in the 1970s reported the occurrence of polyploidy in bone-marrow or peripheral lymphocytes in a number of species, including children, fed on freshly irradiated wheat. Opponents of food irradiation use these studies as evidence that genetic damage is caused by the consumption of irradiated food. This review of those NIN studies and of the attempts to replicate them and of two other relevant studies concludes that the claim that consumption of irradiated food causes genetic damage has not been substantiated. Other researchers have been unable to replicate the NIN studies. Polyploidy appears to be a poor indicator of genetic damage and the NIN results are biologically implausible

    The effect of gamma radiation on Aspergillus flavus and some of its toxic metabolites has been studied. This involved the determination of radio-sensitivity of aflatoxins to gamma radiation and the toxicity of irradiated aflatoxins, the effect of irradiation on the formation of aflatoxins in some Nigerian foodstuffs and on the macronutrients of soya-gari diet, and isolation and characterisation of radiation-induced mutants in A. flavus. A research project is now underway to investigate the effect on nutrients in foodstuffs following the destruction of fungal toxins (aflatoxins) and fungi by gamma irradiation (OGBADU, Ahmadu Bello University, Zaria).

    The irradiation of foods is accepted by international agencies (FAO, OMS) like a healthy and effective technology at the moment the irradiated foods are marketed easily in many countries, however in other countries exist several factors that affect the practical application of this process. In this work is planned about an educational campaign about the irradiation process directed to the consumers. (Author)
