摘要
黄须菜是一种真盐土植物 ,其籽可榨油供食用。黄须菜籽油中含有 90 %以上的不饱和脂肪酸 ,是一种重要的营养保健食品原料。本文研究了用脂肪酶水解黄须菜籽油及其水解产物的后处理工艺。试验了酶、溶剂、温度、碱的流加等条件对水解率的影响 ,确定了适合黄须菜籽油的条件 ,即用质量分数为 5 % L ipolase10 0 T时 ,5 0℃ ,5 h,每 10 min流加碱 ,p H值为 6～ 8时 ,水解率可达 92 %～ 95 %。水解产物中亚油酸含量约72 %。
A process of hydrolyzing Suueda Sulsa seed oil with lipase was studied in this paper. The operating conditions, such as type of lipase, temperature, and reaction time have been studied,. The degree of hydrolysis could be up to 92 [similar to] 95% by 5% Lipolase 100T under optimum conditions, 50°C, 5hr and pH of 6 [similar to] 8. h was experimentally indieated that the hydrolysate contains above 70% Linoleic acid, 13% Oleic acid, 60% Palmitic acid etc. The proposed process is likely a useful method for of producting Linoleic acid.
