INFLUENCE OF $gamma$-IRRADIATION ON SOME KINDS OF FRUITS AND ON CANNED FRUIT (in Russian)
Some results of observations of changes in organoleptic properties of different fresh fruits, their juices, and canned fruit under the influence of gamma irradiation (Co/sup 60/) are given. Irradiation of green persimmons to 1.5 million roentgen at 8500 r/hr leads to the gradual artificial ripening of the fruits. They do not gain any strange taste and are sweeter than the controls. During the same period of time the control green persimmons wither. Figs irradiated with 1.5 million roentgen are well conserved in hermetically closed jars for several weeks without changing their taste. Control flgs go sour in 2 to 3 days under the same conditions. A wild plum is well conserved under gamma irradiation during a month without any changes of its taste or appearance. The total dose reached 1 miilion rcentgen per month. Control plums wither and rot after two or three days. Peaches irradiated in hermetically closed jars conserve their freshness, consistence, color, and taste for weeks when irradiated with 1.5 million roentgen at 8500 r/hr. With further storage the smell and taste of peaches changes sharply, but the appearance and consistence are conserved without any changes for more than 7 months. The control peaches under the same conditions of storage rot after 4 to 5 days. Tangerines and lemons under irradiation acquire a strange taste beginning at 100 thousand roentgen. If they are irradiated with 750 thousand roentgen, the period of storage is doubled or tripled. The irradiated tangerines have the taste of boiled ones. Grapes under the influence of gamma irradiation begin to spoil at 10000 r. Pink and black cherries are conserved for several weeks without changing their organoleptic properties if the dose is 750,000 r and the dose rate is 8500 r/hr. (auth)
