摘要

研究了大麦麦苗粉经,60,Co γ射线辐照杀菌效果以及对其主要成分的影响。结果表明，辐照处理可有效地杀灭麦苗粉中的菌落总数、霉菌、大肠菌群。辐照对其主要成分蛋白质、总糖、游离氨基酸、粗纤维无显著变化.但维生素E的含量随辐照剂量的增加而下降, 辐照10kG比对照下降约35%。建议大麦麦苗粉的商业化辐照加工剂量为7.5－10kGy。

Abstract

Radiation decontamination of barley plant powder by ,60,Co γ-rays and the effect on its components were studied. Results showed that irradiation was very effective in killing the microorganisms in barley plant powder. The irradiation did not cause obvious changes of the major components of protein, total sugar, free amino acid, crude fiber, but 35% loss of vitamin E was observed after 10kGy irradiation. It is suggested that 7.5-10kGy irradiation is good enough for decontamination of the barley plant powder.
