摘要/Abstract

摘要：

以60Coγ射线辐照怀山药，抑制怀山药贮藏期间的生理代谢活动，研究常温贮藏条件下不同辐射剂量抑制发芽和减少贮藏期间重量损失的效果；研究辐射处理对贮藏怀山药主要营养成分的影响，探讨了常温贮藏条件下辐照怀山药蛋白质、氨基酸、可溶性糖的变化规律。实验结果表明，大于70Gy 的辐射剂量可以有效抑制坏山药发芽。经辐照，怀山药的可溶性总糖、粗蛋白和灰分含量均得到提高，其中粗蛋白含量显著提高；但是经过辐照的怀山药的氨基酸含量却低于未辐照的。

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
