摘  要：
研究了γ射线辐照红枣的杀菌效果及其对主要有机营养成分、矿物质、维生素、氨基酸含量及感官品质的影响。试验结果表明:红枣辐照杀菌效果显著,经3×103Gy辐照处理后,5个红枣样品的微生物数量均达到国家标准;辐照对红枣中总糖、蛋白质、矿物质及VA、VE、VB1、VB2含量和感官品质无显著影响;辐照后红枣中粗脂肪含量和氨基酸总量比辐照前有所增加,但不显著(P>0.05);VC含量随辐照剂量的增加显著下降(P<0.01),当辐照剂量为3×103Gy时,其含量比对照降低了20.5%;辐照对红枣的感官品质不仅无不良影响,而且在一定程度上还有改善作用。提出了红枣辐照杀菌的适宜剂量为3×103Gy。

摘  要：
The purpose of this study was to analyze the sterilization effects of irradiation on dried jujubes,and the changes caused by the irradiation in jujube qualities,such as contents of organic nutrition,minerals,vitamins,amino acids as well as sensory qualities of dried jujubes.The results indicated that 1) the microbe indices of the 5 jujube samples sterilized by irradiation with a dosage of 3×10~3 Gy reached the China standard of dried jujube;2) no marked changes in the contents of total sugar,crude protein,minerals,V_A,V_E,V_(B1) and V_(B2),and in the sensory indices were observed;3) the contents of crude fat and the gross of amino acids after irradiation were a little more than those before irradiation(P>0.05);4) the V_C content of dried jujubes sterilized by irradiation decreased significantly with the increases in irradiation dose((P<0.01)),by 20.5% compared with the control at the dosage of 3×10~3 Gy;and 5) irradiation had no adverse effects on sensory qualities,but caused somewhat of improvements in the sensory qualities.It was presented that the feasible irradiation dose for sterilization is 3×10~3 Gy.
