Summary

HERITAGE RASPBERRIES, MATURE AND IMMATURE, WERE SUBJECTED TO GAMMA RADIATION DOSES OF 1, 2 AND 3 KILOGRAYS. THE TREATMENT VERY STRONGLY REDUCES MICROBIAL COUNTS, ESPECIALLY YEASTS. SOME PATHOGENIC MOULD SPECIES ARE LESS AFFECTED BY IONIZATION (PENICILLIUM AND CLADOSPORIUM). THE TREATMENT WITH 1 KILOGRAY MAINTAINS THE TEXTURE AT A LEVEL COMPARABLE TO THAT OF THE CONTROL SAMPLE. THE FIRMNESS OF MATURE OR IMMATURE FRUIT IS MARKEDLY AFFECTED ABOVE 2 KILOGRAYS. IONIZING TREATMENT CAUSES A DECREASE IN CO2 EMISSION AND ETHYLENE PRODUCTION, ALL THE MORE THE HIGHER IS THE DOSE APPLIED. PRACTICALLY, THE TREATMENT WITH 1 KILOGRAY MAINTAINS A SUITABLE SHELF LIFE OF MATURE FRUIT 6 DAYS AT 277 K (4 DEG C), THEN 2 DAYS AT 293 K (20 DEG C) AND OF IMMATURE FRUIT 9 DAYS AT 277 K, THEN 2 TO 3 DAYS AT 293 K.
