摘　　要：采用堆码方式和双源位辐射杀菌工艺,研究了大豆蛋白产品的剂量分布。将钴源先后提升至低位和高位进行一半剂量的产品辐照,产品换位后再如法辐照至设定剂量。检测分析了不同剂量对大豆蛋白卫生学质量、理化指标、功能性和感官等影响。结果表明:用此法进行3—5kGy辐照可达了大豆蛋白辐射杀菌目的,产品的个各项指标良好,也提高了辐射源的利用效率。Dose distribution of soybean protein product irradiated by ^60Co γ-ray with a pile-up irradiation technology was studied. The product bags were irradiated to half dose by the γ-ray source at two positions （low and high）, and the second half dose was delivered in the same way to the product after position-change of the bags. Effects of the γ-ray irradiation, which included hygiene quality, physical and chemical index, functions and appearance of the soybean protein product, were investigated. The results show that decontamination of the product can be achieved by 3-5kGy of the irradiation, with improved utilization efficiency of irradiation source and high quality of the product.
