Abstract

The current trend towards establishing the national programme on food irradiation appears to be maturing with great interest in fundamental and practical problems. Efforts of the Atomic Energy Commission to devise a programme on development studies, and their practical application, which will probably commence in 1967, are now being made. The collaboration of researchers in this field has resulted in the setting-up of the Japanese Research Association. for Food Irradiation. This organization is expected to play an important role in promoting the national programme. At present there are in Japan about 30 kCi-scale sources of radioisotopes, and almost the same number of electron generators, including some pilot-scale irradiation facilities. Practical studies on food irradiation in Japan are classified into three categories, in terms of their purpose. The first is radiation preservation, to which major efforts have been devoted. Sprout inhibition of potatoes, onions and sweet potatoes, disinfestation of rice, wheat and their products, low-dose treatment of vacuum-sealed fish and shell-fish with doses of less than 0.5 Mrad, and of some fruits, such as strawberry and orange, are the examples which are considered to be potential subjects for radiation treatment. The first interesting observation was in rice irradiation where, at 5000  More>>

abstractNote = {The current trend towards establishing the national programme on food irradiation appears to be maturing with great interest in fundamental and practical problems. Efforts of the Atomic Energy Commission to devise a programme on development studies, and their practical application, which will probably commence in 1967, are now being made. The collaboration of researchers in this field has resulted in the setting-up of the Japanese Research Association. for Food Irradiation. This organization is expected to play an important role in promoting the national programme. At present there are in Japan about 30 kCi-scale sources of radioisotopes, and almost the same number of electron generators, including some pilot-scale irradiation facilities. Practical studies on food irradiation in Japan are classified into three categories, in terms of their purpose. The first is radiation preservation, to which major efforts have been devoted. Sprout inhibition of potatoes, onions and sweet potatoes, disinfestation of rice, wheat and their products, low-dose treatment of vacuum-sealed fish and shell-fish with doses of less than 0.5 Mrad, and of some fruits, such as strawberry and orange, are the examples which are considered to be potential subjects for radiation treatment. The first interesting observation was in rice irradiation where, at 5000 to 20 000 rad disinfestation dose, quality changes detectable immediately after irradiation became insignificant after eight months' storage according to the statistical analysis of organoleptic data. The second was in connection with studies on the elimination of harmful biological and biochemical factors in foods from the viewpoint of public health. Radiation sensitivity of the toxin produced by Cl. botulinum, Type E| was investigated in studying the wholesomeness of irradiated foods. The third was concerned with the utilization of the chemical effect of radiation. For example, studies were made of the irradiation of marine algae with 0.5 to 0.7 Mrad to improve quality and the yield of extracted agar and the radiation acceleration of the ageing of alcoholic beverages, particularly distilled liquors, with doses of up to 0.5 Mrad. Besides these practical investigations, extensive work has been conducted with the fundamental aspects, including the radiosensitization of microorganisms, enzyme inactivation by radiation, and other subjects in radiation chemistry associated with food irradiation. (author) [French] Actuellement, l'organisation du programme national d'irradiation de produits alimentaires semble se preciser, l'interet se portant a la fois sur les problemes fondamentaux et les questions pratiques. La Commission de l'energie atomique s'occupe activement d'elaborer le programme d'etudes et de realisations qui sera mis en oeuvre vraisemblablement en 1967. La collaboration des chercheurs dans ce domaine a abouti a la creation de l'Association japonaise de recherches sur l'irradiation des denrees alimentaires, organisme qui est appele a jouer un role important dans le developpement du programme national. Le Japon dispose actuellement de quelque 30 sources de radioisotopes de l'ordre du kCi et d'autant de generateurs d'electrons, y compris quelques installations experimentales. Les etudes pratiques sur l'irradiation de denrees alimentaires au Japon sont orientees dans trois directions. Premierement, la radioconservation, qui beneficie de l'effort principal. L'inhibition de la germination des pommes de terre, des oignons et des patates, la desinsection du riz, du ble et de leurs derives, et le traitement a faible dose (moins de 0,5 Mrad) en emballages sous vide du poisson et des crustaces et mollusques ainsi que de quelques fruits tels que la fraise et l'orange sont autant d'exemples des possibilites d'utilisation des rayonnements. L'irradiation du riz a permis de faire une observation interessante, a savoir qu'a la suite d'une irradiation de desinsection a des doses comprises entre 5000 et 20 000 rad, les modifications de qualite decelables immediatement apres l'irradiation se sont revelees insignifiantes apres huit mois de conservation d'apres l'analyse statistique des donnees organoleptiques. Deuxiemement, etude de l'elimination des agents biologiques et biochimiques nuisibles dans les produits, du point de vue de la sante publique. La sensibilite aux rayonnements de la toxine produite par Cl. botulinum E a ete etudiee en rapport avec l'innocuite des produits irradies. Troisiemement, l'utilisation des effets chimiques des rayonnements. On a etudie par exemple l'irradiation d'algues marines a des doses de 0,5 a 0,7 Mrad en vue d'ameliorer la qualite et la quantite de la gelose extraite, ainsi que l'acceleration, par des doses de rayonnement atteignant 0,5 Mrad, du vieillissement des boissons alcooliques, notamment des liqueurs distillees. Outre ces etudes de caractere pratique, on s'est occupe activement des problemes fondamentaux comprenant la radiosensibilisation des micro-organismes, l'inactivation des enzymes par les rayonnements et d'autres questions de radiochimie interessant l'irradiation des denrees alimentaires. (author) [Spanish] En la actualidad parecen perfilarse los planes para establecer en el Japon un programa nacional de irradiacion de alimentos orientado hacia los problemas fundamentales y practicos. La Comision de Energia Atomica ha comenzado ya a preparar el programa de estudios fundamentales y sus aplicaciones, que se emprendera probablemente en 1967. Gracias a la colaboracion de especialistas se ha constituido la Sociedad japonesa de investigaciones sobre irradiacion de alimentos; se espera que esta organizacion desempene una labor importante en la ejecucion del programa nacional. En la actualidad, el Japon dispone de unas 30 fuentes radioisotopicas del orden del kilocurie, y casi del mismo numero de generadores de electrones, incluidas varias plantas piloto de irradiacion. En el Japon los estudios practicos sobre irradiacion de alimentos se clasifican en tres.categorias, segun la finalidad. La primera comprende los estudios sobre conservacion, a los que se dedican los mayores esfuerzos. Entre las aplicaciones interesantes de las radiaciones que cabe mencionar figura la inhibicion de la germinacion de patatas, cebollas y batatas, la desinfestacion de arroz, trigo y sus derivados, el tratamiento-en dosis ligeras (inferiores a 0,5 Mrad) de pescado y mariscos envasados al vacio, asi como de algunas frutas, tales como fresas y naranjas. Una observacion interesante, en lo que se refiere a la irradiacion del arroz en dosis de 5000 a 20 000 rad para desinfestarlo, es que los cambios de calidad apreciables inmediatamente despues de la irradiacion resultaron insignificantes en el analisis estadistico de datos organolepticos efectuado al cabo de ocho meses de almacenamiento. La segunda categoria comprende los estudios sobre eliminacion de agentes nocivos (biologicos y bioquimicos) de los alimentos desde el punto de vista sanitario. Se ha investigado, en relacion con la comestibilidad de los alimentos irradiados, la sensibilidad a la irradiacion de la toxina producida por el Cl. botulinum tipo E. La tercera categoria comprende los estudios referentes al aprovechamiento de los efectos quimicos de las radiaciones. Cabe citar, como ejemplo, la irradiacion de algas marinas con dosis de 0,5 a 0,7 Mrad para mejorar la calidad y rendimiento del agar extraido, y la aceleracion por irradiacion del envejecimiento de bebidas alcoholicas, sobre todo de licores destilados, con dosis no superiores a 0,5 Mrad. Ademas de estas investigaciones practicas se han realizado amplios estudios sobre algunos aspectos fundamentales: radiosensibilizacion de microorganismos, inactivacion de enzimas por irradiacion y'otras cuestiones de radioquimica referentes a la irradiacion de alimentos. (author) [Russian] V nastojashhee vremja, kak predstavljaetsja, sushhestvuet bol'shoj interes i vyrisovyvaetsja tendencija v otnoshenii vyrabotki nacional'noj programmy po oblucheniju produktov pitanija v oblasti kak fundamental'nyh, tak i prakticheskih problem. V nastojashhee vremja Komissija po atomnoj jenergii predprinimaet usilija po razrabotke programmy issledovanij metodov i ih prakticheskogo primenenija, kotoraja, verojatno, nachnet osushhestvljat'sja v 1967 godu. Sotrudnichestvo issledovatelej v jetoj oblasti privelo k sozdaniju Japonskoj issledovatel'skoj associacii po oblucheniju produktov pitanija, i jeta organizacija, kak ozhidaetsja, budet igrat' vazhnuju rol' v razrabotke nacional'noj programmy. V nastojashhee vremja v Japonii imeetsja okolo 30 radioizotopnyh istochnikov porjadka kilokjuri i pochti takoe zhe chislo generatorov jelektronov, vkljuchaja neskol'ko krupnyh obluchajushhih ustanovok. Prakticheskie issledovanija po oblucheniju produktov v Japonii razdeljajutsja na tri kategorii v zavisimosti ot ih celi. Pervaja - jeto predohranenie produktov pitanija ot.porchi s pomoshh'ju obluchenija; jetim issledovanijam udeljaetsja glavnoe vnimanie. Zaderzhka prorastanija kartofelja, luka i batata, obezzarazhivanija risa, pshenicy i izdelij iz nih i obrabotka nebol'shimi dozami germeticheski upakovannoj ryby i vodnyh zhivotnyh, imejushhih pancir', pri velichine dozy menee 0,5 Mrad i nekotoryh fruktov, takih kak klubnika i apel'siny, - jeto primery potencial'nogo primenenija obluchenija. Interesnoe nabljudenie pri obluchenii risa sostojalo v tom, chto pri obezzarazhivajushhej doze v 5 000- 20 000 rad kachestvennye izmenenija, obnaruzhimye neposredstvenno posle obluchenija, stali posle vos'mimesjachnogo hranenija neznachitel'nymi pri statisticheskom analize organolepticheskih dannyh. Vtoraja kategorija - jeto issledovanija po ocenke vrednyh biologicheskih i biohimicheskih faktorov v produktah pitanija s tochki zrenija zdravoohranenija. Chuvstvitel'nost' k oblucheniju, proizvedennogo Cl. botulinum tipa E, issledovalas' v svjazi s celostnost'ju obluchennyh produktov pitanija. Tret'ja kategorija svjazana s ispol'zovaniem himicheskogo vozdejstvija obluchenija. Naprimer, issledovalos' obluchenie morskih vodoroslej dozami v 0,5 -0,7 Mrad dlja uluchshenija kachestva i vyhoda jekstragirovannogo agara i radiacionnoe uskorenie starenija alkogol'nyh napitkov, osobenno ochishhennyh likerov, dozami do 0,5 Mrad. Krome jetih prakticheskih issledovanij provodilas' shirokaja rabota po fundamental'nym aspektam, vkljuchaja radiochuvstvitel'nost' mikroorganizmov, inaktivaciju fermentov oblucheniem i drugie problemy radiacionnoj himii, svjazannoj s oblucheniem produktov, pitanija.
