Process for enriching unsaturated fatty acid from safflower seed oil via enzymatic hydrolysis

The invention belongs to the field of food processing and particularly relates to a process for enriching unsaturated fatty acid from safflower seed oil via enzymatic hydrolysis. The process comprises: adding an enzyme to safflower seed oil, enzymatically hydrolyzing, enzymatically deactivating, centrifuging to obtain supernate oil, freezing the supernate oil, and thawing to room temperature to obtain supernate that is unsaturated fatty acid. Through reaction, lipase herein is effective in separating saturated fatty acid and unsaturated fatty acid in oil; the saturated fatty acid is frozen and solidified during low-temperature freeze-centrifuging, and the unsaturated fatty acid is separated. The process is good in convenience and higher in extraction rate of unsaturated fatty acid. 本发明属食品加工领域，具体涉及种酶法水解红花籽油富集不饱和脂肪酸工艺。所述工艺包括：将红花籽油中加入酶，酶解，灭酶，离心得到上清油脂进行冷冻处理，再解冻至室温，上清液即为不饱和脂肪酸。本发明脂肪酶通过反应有效分离油脂中饱和脂肪酸与不饱和脂肪酸，在低温、冷冻离心的过程中，使得饱和脂肪酸冷冻凝固，不饱和脂肪酸得以分离出来。此方法便捷，又加大了不饱和脂肪酸的提取率。
