One of the organic compounds more sensitive to temperature, storage and radiation is ascorbic acid. In an irradiation plant quarantine treatment, be processed fruits and vegetables, vegetable carriers of vitamin C. Was irradiated at a given concentration of vitamin C (42.24 mg/100 ml) contained in 3 different media: orange juice in water solution and pure ascorbic acid crystals, then diluted in water, we applied different doses of radiation Gamma (0, 0.1, 1.0, and 10 kGy), the dose rate was 7.433 GY / min.The results showed that higher percentages of vitamin C destruction irradiated to the respective doses were presented in the solution of vitamin C contained in water, (15.62, 64.11 and 84.38%) due to the indirect effect of gamma radiation , then vitamin C contained in orange juice, (5.25, 7.33 and 50.50%) This is because the other constituents of orange juice, have a protective effect o...

irradiation technology replaces additives and chemical fumigants in the conservation and elimination of insects in food. These chemicals are very questionable to be highly toxic, harmful to health and the environment. We present research using gamma radiation in Peruvian asparagus (fresh asparagus, freeze-dried and flour). Doses of 1 kGy extend the half-life of fresh green asparagus for 20 days and of the control for only 10 days. The quality of freeze-dried asparagus irradiated to 3, 5 and 7 kGy was evaluated by microbiological, physicochemical and sensorial tests. a dose of 3 kGy improved the hygienic quality of freeze-dried asparagus. irradiation was evaluated as a quarantine treatment for the disinfestation of copitarsia decolora in asparagus. a dose of 0.10 kGy applied to the second instar of copitarsia decolora larvae was required to prevent adult emergence. Gamma radiation in Peru...
