The effect of gamma radiation on the chemical content texture and shelf life of papaya

Muhamad Samudi Yasir, . The effect of gamma radiation on the chemical content texture and shelf life of papaya. pp. 15-23. ISSN 0128-0155

Commercially matured papaya carica papaya var. solo were gamma irradiated at doses of 0 kGy 0.75 kGy 1.0 kGy and 1.5 kGy. The production rate of ethylene development of ripening colour pectin substances and ascobic acid content as well as the weight losses were studied during storage at room temperature. Ethylene production development of ripening colour and softening were found to be retarded by irradiation. Irradiation also slowed down the reduction rate of alcohol insoluble substances and hydrochloric acid soluble pectin and the increment of water soluble pectin and hexametaphosphate soluble pectin. Doses of 1.0 kGy and 1.5 kGy effectively suppressed the synthesis of vitamin C although no effect on the exixting ascorbic acid was detected. The weight losses of papaya were not affected by irradiation treatment

Abstract

Commercially matured papaya carica papaya var. solo were gamma irradiated at doses of 0 kGy 0.75 kGy 1.0 kGy and 1.5 kGy. The production rate of ethylene development of ripening colour pectin substances and ascobic acid content as well as the weight losses were studied during storage at room temperature. Ethylene production development of ripening colour and softening were found to be retarded by irradiation. Irradiation also slowed down the reduction rate of alcohol insoluble substances and hydrochloric acid soluble pectin and the increment of water soluble pectin and hexametaphosphate soluble pectin. Doses of 1.0 kGy and 1.5 kGy effectively suppressed the synthesis of vitamin C although no effect on the exixting ascorbic acid was detected. The weight losses of papaya were not affected by irradiation treatment
