荠蓝籽冷榨制油和荠蓝籽油精炼工艺研究

Preparation of Camelina sativa seed oil by cold-pressing and its refining technology

以冷榨技术获取88％．92％的荠蓝籽压榨油，采用磷酸脱胶-干法脱胶-脱色-脱酸脱臭工艺实现荠蓝籽油的物理精炼，得到了占压榨油收率95．5％的精炼荠蓝籽油。荠蓝籽油脂肪酸组成中，n-3不饱和脂肪酸α-亚麻酸含量达到34．5％，必需脂肪酸（n-6系列的亚油酸、花生四烯酸和n-3系列的α-亚麻酸）达到53．9％，各种不饱和脂肪酸含量达91％，荠蓝籽油是一种高价值食用植物油。

88% - 92% pressed oil from Camelina sativa seed was obtained with cold pressing. Camelina sativa oil with 95.5 % refining yield was got by using phosphorus acid deguming - dry deguming - bleaching - physical purifying process to deacidfy and deodor. In Camelina sativa oil, the α- linolenic acid（ 18：3n - 3PUFA） content was 34.5%, essential PUFA（ 18： 3 n - 3 a - linolenic acid and 18 ： 2 n - 6 linolenic acid, etc） content was 53.9 %, unsaturated fatty acid content was 91%. Camelina sativa oil is a super- value edible oil.
