摘要:

薏苡仁油富含不饱和脂肪酸,具有较高的营养与药用价值。以酸价和过氧化值为指标对不同温度、光线、空气和抗氧化剂存放条件下的薏苡仁油进行氧化稳定性研究。结果表明:温度、光线和空气均可加速薏苡仁油的氧化,其中温度对薏苡仁油的氧化影响最大;添加抗氧化剂可明显提高薏苡仁油的稳定性,其抗氧化效果VE 强于TBHQ。

关键词: 薏苡仁油, 氧化稳定性, 酸价, 过氧化值

Abstract:

In order to explore the oxidative stability of coix seed oil, acid value and peroxide value of coix seed oil stored under different conditions such as temperature, light, air and antioxidants were measured. Results showed that temperature, light and air all could accelerate the oxidation of coix seed oil and among them temperature was the most critical factor. Higher stability was observed in coix seed oil with the additions of antioxidants such as vitamin E and TBHQ. Furthermore, vitamin E exhibited stronger antioxidant effect than TBHQ.

Key words: coix seed oil, oxidative stability, acid value, peroxide value
