Gamma-irradiation and storage effects on some chemical aspects of carrots. 1977

F A Ismail, and S A Afifi, and A A Fahmy

Studies on chemical changes induced by gamma-irradiation at optimum dose of 75 krad in carrots were undertaken. Sugars, nitrogen, free amino acids, amino acids of alcohol insoluble solids, and pectin fractions were determined. The results indicate that the postharvest irradiation of carrots does not dramatically affect their chemical composition during storage. However, it was observed that storage time affected significantly the biochemical changes occurring in the constituents of carrots exposed to gamma-irradiation.
