Abstract

Abstract:

This study aimed to explore the application feasibility of 60Coγ radiation in storage of Huai Rhizoma dioscoreae. The effects of different radiation dosages of 60Coγ on inhibiting germination and reducing weight loss during storage at room temperature were investigated, and the contents of crude protein, soluble sugar, ash and amino acids of Huai Rhizoma dioscoreae before and after radiation were compared respectively. The results showed that more than 70 Gy of 60Co γ can effectively inhibit germination. 60Co γ radiation can increase the contents of crude protein, soluble sugar and ash increase, especially the ash content is increased markedly, whereas the contents of amino acids are decreased. In conclusion, 60Co γ radiation is available.

Key words: 60Coγ-ray radiation, Huai rhizome dioscoreae, radiation storage preservation
