高能电子束辐照对奇亚籽发芽率及奇亚籽毛油品质的影响

摘要

奇亚籽繁殖力超强,引入我国易形成优势种群,破坏生态系统,因此考虑对奇亚籽进行灭活后引入.探究利用辐照技术使奇亚籽丧失活力,并研究辐照对奇亚籽毛油品质的影响.结果表明:辐照处理可延缓奇亚籽开始萌发的时间,并使其发芽率降低,随着辐照剂量的增大,10 kGy处理时奇亚籽发芽率为0;10 kGy辐照处理与不经辐照处理的奇亚籽毛油相比,酸值显著升高(P＜0.05)(但仍符合亚麻籽油的一级标准),过氧化值、脂肪酸组成差异不显著(P＞0.05);辐照处理后奇亚籽毛油的品质高,符合亚麻籽油的一级标准.%Chia(Salvia hispanica) seed with super fertility introduced into China easily formed the dominant population,and destructed the ecological system.Therefore,the Chia(Salvia hispanica) should be introduced after the seeds were inactivated.Chia(Salvia hispanica) seed lost vitality because of irradiation,and the effects of irradiation on crude Chia(Salvia hispanica) seed oil quality were studied.The results showed that the irradiation could delay Chia(Salvia hispanica) seed germination,and the germination rate decreased with irradiation dose increasing.The germination rate of Chia(Salvia hispanica) seed decreased to 0 after 10 kGy treatment.The acid value of crude Chia(Salvia hispanica) seed oil with 10 kGy irradiation increased significantly (P ＜ 0.05)(still in accordance with the first level standard of linseed oil) compared with no irradiation,peroxide value and the fatty acid composition had no significant difference (P ＞ 0.05).The quality of crude Chia (Salvia hispanica) seed oil after irradiation was high,in accordance with the first level standard of linseed oil.
