对α-亚麻酸及其乙酯分别在氧气气氛和氮气气氛下进行一定剂量的γ辐射,每隔2d测定其过氧化值.研究结果表明,辐射剂量和时间对亚麻酸的过氧化值有较大影响;同时探讨了亚麻酸在γ辐射下过氧化值与反应机制之间的内在联系. A-linolenic acid and its ethyl ester were exposed to a certain amount of γ radiation in an oxygen atmosphere and a nitrogen atmosphere respectively, and the peroxide value was measured every 2 days. The results showed that the peroxide dose and time had a greater effect on the peroxide value of linolenic acid In addition, the intrinsic relationship between the peroxide value and the reaction mechanism of linolenic acid under γ irradiation was discussed.
