摘要
以姜油树脂为原料,研究其对油脂的抗氧化作用及其稳定性。结果表明:油脂中添加一定量的姜油树脂后,油脂的抗氧化能力得到了提高,但随着添加量的增大,体系过氧化值减小的幅度减少,添加量在100-150 mg/kg较为适宜。姜油树脂稳定性较好,在100℃,太阳光照射、酸性条件下呈现良好的稳定性,并可长期常温存储,但其在碱性溶液中不稳定。
Using ginger oleoresin as raw materials,this paper focused on antioxidation and stabiliy of ginger oleoresin on fat and oil.The results showed that when a certain quantity ginger oleoresin were added in oil,the antioxidation of oil were improved.But as the quantity enlarging,the system peroxide number decreased in descending extent.Generally,the suitable addition was 100 -150 mg/kg.The ginger oleoresin was stable under temperature 100 ℃,sunlight,acidic condition.However,it was not good in alkalinity,and could storage for long time.
