Studies on the storage of irradiated potatoes

Abstract

Tubers of alpha and king edward potato cultivars were exposed to O, 10 or 50 krad and stored under room temperature and good ventilation in perforated standard carton boxes. 10 Krad was the promising dosage for sprouting inhibition for both the two cultivars. Total losses in weight were partially dependent on the volume of the dosage, the time elapsed after irradiation and cultivar used. Ascorbic acid slightly decreased, whilst sugar fractions were increased during storage in irradiated tubers. Sugar fractions were sharply decreased in boiled or fried potatoes. Also, chlorogenic acid was increased by prolonging the storage time and/or increasing the exposure dose. After-cooking discoloration (darkening) was reduced by gamma irradiation and/or extending the storage period. Using 0.5% citric acid or 0.5% sodium citrate solution inhibited the after-cooking discoloration. 8 tabs.
