【摘要】 研究了国内市场上销售的不同产地红曲米粉的辐射灭菌效果,对辐照红曲米粉的感官指标、理化指标和微生物指标进行了检测,结果表明:6kGy以上的γ射线可以有效杀灭红曲米粉中的微生物,辐照红曲米粉的感官指标、主要营养成分与未辐照无明显差异,但会导致色价的降低。商业化应用效果表明,采用静态堆码辐照,工艺剂量上限和下限分别为6kGy和8kGy,总体平均吸收剂量控制在7kGy,可确保红曲米粉的卫生质量、色价损失率在2%以下。更多还原

【Abstract】 The effect of radiation sterilization of red kojic rice powder sold in domestic market was studied. The indices of sensory organ,nutrition and microbe of irradiated red kojic rice powder were tested.It shows that microorganism in red kojic rice powder can be killed effectively byγ-rays of more than 6 kGy and there is no significant difference in the sensory organ index and nutritional composition of red kojic rice powder between irradiated and non-irradiated powder.Irradiation can result in decrease of chroma of red kojic rice powder.The effect of commercial application indicated hygienic quality of irradiated red kojic rice powder in radiation dose between 6-8 kGy is superior and the rate of chroma loss was less than 2%.更多还原
