Example Embodiment

[0029] Example 1

[0030] The degummed flaxseed is dry crushed with a portable Chinese medicine crusher, the crushed flaxseed and water are mixed in a ratio of 1:5, the pH is adjusted to 9.0, the temperature is 60°C, and 1.5% alkaline of the raw material mass is added. Protease, after 5 hours of enzymolysis, adjust the pH to 5.0, cool to 50°C, add 1.5% composite cellulase of raw material mass, and then enzymolyse for 5 hours, centrifuge to obtain free oil, and centrifuge the obtained emulsion again to obtain The total free oil, calculated free oil yield, can reach 82.26%.

Abstract

The invention relates to aqueous enzymatic extraction of flax-seed oil. It uses degumming flax-seed as material, processes smashing, enzymolysis, and centrifuging to gain flax-seed oil. It is processed enzymolysis by alkali protease and compound cellulose enzyme to increase free oil yield which has higher quality, easy fining, higher nutritive value and functional performance. Compared with the traditional expression and solvent extraction method, it has the advantages of simple device, safe operation, litter pollution, low energy consumption etc.

Description

technical field [0001] The invention discloses a method for extracting linseed oil by an aqueous enzymatic method, which belongs to the technical field of oil extraction technology by an aqueous enzymatic method. Background technique [0002] With the improvement of people's living standards, there are further requirements for functional and nutritious edible oils. Flaxseed oil has attracted more and more attention because of its high nutritional value and good functional properties. The output of linseed has ranked seventh among the world's top ten oil crops. In my country, its annual output is about 400,000 tons, ranking fourth in the world, and has become an important vegetable oil in my country. [0003] Unsaturated fatty acids in linseed oil are more than 80%, oleic acid is 13% to 29%, linoleic acid is 15% to 30%, linolenic acid is 40% to 60%, of which α-linolenic acid content is very high, α-linolenic acid It is an essential fatty acid for the human body. It can be ...
