γ-辐照处理对谷物储藏及品质特性的影响研究进展

Reasearch progress in gamma-irradiation research on storage and quality of cereals

辐照作为一种低能耗、安全、有效的加工方式在食品工业上得到广泛应用。辐照对储藏谷物的主要作用包括:适宜剂量的辐照可杀害储粮中的害虫,且不会影响谷物品质;控制谷物中常见的致病菌,产毒菌素的生长,降解致病霉菌;通过作用于淀粉颗粒,提高谷物的营养品质和食用品质;另外,辐照还可延缓谷物老化,劣变的过程,提高保鲜期,提高谷物成品的生产效率。本文综述了辐照对谷物食品品质和营养的影响,分析评价了食品辐照的优劣及国际机构对辐照食品的认可进程,并对消费者的接受度等辐照领域的相关问题提出建议。

Food irradiation was a low -energy, safety and effective way of storing and processing foods, which was widely used in food industry. There are lots of advantages of irradiation in stored grain： appropriate dose of radiation could kill pests in stored grain,and does not affect the grain quality. Controlling the growing of some common pathogenic bacteria and toadstool, degrading the disease -causing mold. By acting on starch particles, irradiation could improve the nutritional quality and eating quality of grain. In addition, irradiation could delay the ageing of the grain, and the deterioration process, improving the shelf time and increasing the productivity of the grain. This paper combined the effect of irradiation in the field of food quality and nutrition, evaluated the advantages and disadvantages of food irradiation and the recognition process of irradiated foods among international institutions. In the end ,some advices about the acceptance of the consumer and other related issues were gived in the field of irradiation.
