The invention belongs to the technical field of edible oil processing, in particular to a dephosphorization method using high-speed shear eddy current mixing assistant biological enzymes. The compound enzyme solution composed of phospholipase A1 and phospholipase C is used for enzymatic dephosphorization of crude oil. In the process, high-speed shearing and eddy current mixing are used to promote the full enzymatic hydrolysis reaction between the compound enzyme and phospholipid, so that the phospholipid can be converted into diethyl glyceride, and the diethyl glyceride can be dissolved in the oil as a part of edible oil, without producing other by-products, and the safety is better, and the degumming oil is improved. Yield. Compared with the existing traditional degumming method, the amount of enzymatic raw materials in the method is greatly reduced, the compound enzymes can be recycled, and the flavor of pressed peanut oil can be well preserved, the amount of enzymatic addition can be greatly reduced, the enzymatic hydrolysis time can be shortened, the sewage discharge can be reduced, the production cost can be reduced, and the oil yield can be improved. The method has good popularization value and application prospect.
【技术实现步骤摘要】
一种利用高速剪切涡流混合辅助生物酶的脱磷方法
本专利技术属于食用油加工
,尤其涉及一种利用高速剪切涡流混合辅助生物酶的脱磷方法。
技术介绍
植物油精炼一般包括脱磷、脱酸、脱色、脱蜡和脱臭等工序。脱磷是毛油精炼的第一工序,用于从毛油除去磷脂和粘液物质。毛油中的磷脂分为水化磷脂和非水化磷脂,水化磷脂具有亲水性,非水化磷脂含量较高的毛油适合采用生物酶法进行脱磷。酶法有反应专一、反应条件温和及较少的环境污染等优点,使其更具有竞争力。与传统的水化脱磷工艺相比,酶法脱磷可以减少大量的酸和碱的使用,降低脱胶油的精炼损失,且很好地保留压榨压榨花生油的风味,大大节约化学物质的消耗量,减少精炼过程中产生的废水,提高产品质量和降低操作成本,在环保、经济、质量等方面具有潜在的优势。已有文献报道的食用油脱磷普遍采用化学法脱磷和单一酶法脱磷。化学法脱磷主要采用磷酸溶液对毛油进行处理,该方法不仅对食用油风味影响很大,而且使得脱磷后的食用油酸价增加,为降低酸价,需要加碱进行碱炼,使得毛油发生乳化,大大降低油脂得率;单一酶法脱磷主要是只采用一种磷脂酶对毛油进行处理,该方法酶制剂用量大,酶处理 ...
