Abstract

The invention provides a microwave ultrasonic-assisted aqueous enzymatic method for extracting linseed oil. The method comprises the following steps: 1, screening linseed, and carrying out drying and pulverizing sequentially to obtain linseed powder; 2, uniformly mixing any one or more of cellulase, hemicellulase, pectolase and beta-glucanase with protease to obtain a complex enzyme; 3, adding deionized water, the linseed powder and the complex enzyme in a microwave ultrasonic wave combined type reaction kettle for enzymolysis to obtain an enzymatic hydrolysate; 4, performing solid-liquid separation to obtain the linseed oil. The method has the advantages of being high in oil content and extraction efficiency, so that a new effective way is provided for extraction of the linseed oil from the linseed.

Description

technical field [0001] The invention belongs to the technical field of vegetable oil extraction, and in particular relates to a method for extracting linseed oil by a microwave-ultrasonic assisted aqueous enzymatic method. Background technique [0002] Linseed oil, also known as linseed oil or flax oil, is mainly composed of linolenic acid, linoleic acid, oleic acid, stearic acid, palmitic acid and other fatty acids, of which the content of linolenic acid is as high as 55%, so linseed oil is the world's One of the vegetable oils with the highest linolenic acid content. The linolenic acid in linseed oil belongs to α-linolenic acid. α-linolenic acid is an essential fatty acid for the human body every day. It is a core substance of life and an important component of human brain cells and tissue cells. Humans cannot synthesize flax by themselves Acid must be obtained from food or nutritional supplements. At the same time, linseed oil has a strong effect of increasing intellige...
