Gamma radiation effects on some biochemical changes in potato tubers at different storage periods [electronic resource].

Includes reference.

The effect of gamma irradiation on some biochemical compounds of potato tubers "alph''; during different periods of storage; was studied. Irradiation doses 0, 10, 20 and 40 Gy before planting and 0, 80,160 and 320 Gy after planting were used as two different storage methods. Also, the effect of periodic time storage at 0. 30, 60. 90 and 120 days on biochemical compounds Was investigated. The changes in biochemical compounds such as; total phenolic compounds, chlorogenic acid and peroxidase enzyme activity by colorometric spectroscopic analysis were followed. Glycoalkaloids were determined by HPLC technique. The results proved that the storage was much better and more predominent in the first than the second method.
