以橡胶籽仁为原料,采用压榨法、浸出法、超声波辅助溶剂法和水酶法制备橡胶籽油。比较不同提取工艺的油脂提取率、理化性质及脂肪酸组成。结果表明:超声波辅助溶剂法油脂提取率最高,水酶法的最低;水酶法得到的橡胶籽油的水分及挥发物含量较高;浸出法所得橡胶籽油的酸价最高,压榨法的最低;压榨法橡胶籽油过氧化值最高,水酶法的最低; 4种提取工艺所得橡胶籽油的脂肪酸组成基本相同。

Rubber seed oil was separately extracted from rubber seed by pressing method,leaching method, ultrasound - assisted solvent method and aqueous enzymatic method. The oil extraction rates,physicochemical properties and fatty acid compositions of rubber seed oils obtained by different processes were compared. The results showed that the ultrasound - assisted solvent method had the highest oil extraction rate,while that of aqueous enzymatic method was the lowest. The content of water and volatile matter in the oil obtained by aqueous enzymatic method was higher. The leached rubber seed oil had the...
