棉籽油冬化分提中试试验工艺研究
China Oils and Fats(2013)
Abstract
介绍了以三级棉籽油为原料,采用冬化分提工艺制取高品质棉籽油的工艺。试验表明:采用分提工艺得到的棉籽油液体油冷冻试验可达11 h以上,完全符合一级棉籽油冷冻试验的要求;与未分提棉籽油脂肪酸组成相比,棉籽油液体油中棕榈酸降低1.81个百分点,棕榈一烯酸降低0.062 2个百分点,硬脂酸降低0.395个百分点,油酸增加0.17个百分点,亚油酸增加1.79个百分点,亚麻酸增加0.104 9个百分点;棉籽油固体脂中棕榈酸增加13.19个百分点,棕榈一烯酸降低0.210 5个百分点,硬脂酸增加1.582个百分点,油酸降低2.02个百分点,亚油酸降低10.85个百分点,亚麻酸降低0.047 6个百分点。
