Abstract

The invention discloses a cold-pressing production method of linseed oil and relates to the technical field of edible oil processing. The method includes: preprocessing, to be more specific, screeninglinseeds with a screening device, and using a chain type dryer to dry the linseeds; performing one-step pressing; filtering; performing winterization and dewaxing, to be more specific, cooling the filtered crude oil in a cooling tank at 6-12 DEG C for 4-8 hours while keeping the slow flowing of the crude oil, and storing the crude oil in a crystallization tank for 6-10 hours, wherein the storagetemperature is 4-8 DEG C lower than the temperature in the cooling tank; performing refined filtration. The cold-pressing production method has the advantages that compared with a solvent extraction method, the cold-pressing production method greatly reduces the use of organic solvents and can produce the linseed oil without solvent residues; compared with a traditional hot pressing method, the cold-pressing production method keeps the rich active substances such as alpha-linolenic acid and vitamin E in the linseeds to a great extent and solves the problem that the linseed oil produced by theexisting hot pressing method is low in quality.

Description

technical field [0001] The invention relates to the technical field of edible oil processing, in particular to a cold pressing production method of linseed oil. Background technique [0002] Flax, also known as flax, is an annual herb and is also the main economic oil crop in my country. Flaxseed is the seed of flax, and its oil content is generally 38%-45%. The main component of linseed oil is unsaturated fatty acid—α - Linolenic acid and linoleic acid, of which alpha-linolenic acid content is 45%-65%. Flaxseed oil has special physiological effects due to its unique fatty acid composition. The intake of α-linolenic acid is of great significance to human metabolism. Not only does it have certain nutritional functions, but it can also be converted into EPA and DHA in the body. Clinical studies have shown that α-linolenic acid has various important physiological functions and pharmacological activities such as regulating blood lipids, lowering cholesterol, anti-inflammation, a...
