食品经~(60)Co-γ射线照射后,可以延长其保存期限,这对减少食品损失,丰富市场供应具有重要意义。本试验通过血浆皮质醇含量测定来评价辐照食品对机体的肾上腺皮质功能有无影响,作为安全性评价的一部分。 对象与方法 1.动物实验 选用重约50 g左右的Wistar大鼠187只,分四组:甲组(56只)全部用辐照食品饲养;乙组(54只)仅蔬菜为辐照食品;丙组(60只)用未辐照食品饲养,食谱同上,作对照组;丁组(17只)饲 After the food is irradiated by ~ (60) Co-γ rays, the shelf life of the food can be prolonged, which is of great significance for reducing food loss and enriching the market supply. This test to assess the plasma cortisol content of irradiated foods on the body’s adrenal function have no effect, as part of safety evaluation. Subjects and methods 1. Animal experiments 187 Wistar rats weighing about 50 g were selected and divided into four groups: Group A (56) were all irradiated with irradiated food; Group B (54) only irradiated food; Group C (60) were fed with unirradiated food, the same recipe as the control group; group D (17)
