摘要:

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。

关键词: &gamma, 辐射, 亚麻酸, 过氧化值, 氢过氧化物

Abstract:

α-linolenic acid and α-linoleate ethylester were sampled in glass bottles charged with air and nitrogen and were irradiated with 60Co at different dose levels.Peroxide values of the samples were determined every two days.The results showed that the irradiat ion dose and t ime have great effects on the peroxide value of the linolenic acid.Relationships between the peroxide value and reaction mechanism under the γ-irradiation were discussed.

Key words: γ, -irradiation, linolenic acid, peroxide value, hydroperoxide
