Description
Technical field
Present invention relates particularly to a kind of linseed oil and preparation method thereof.
Background technology
Flax (Classification system Linum usitatissimum L.), also known as linum sativum, crow fiber crops, belong to Angiospermae
The annual herb plant of Dicotyledoneae linum.Linseed is the seed of flax.
Linseed oil extracting methods mainly have milling process, lixiviation process, supercritical CO2Method and aqueous enzymatic method.Edible linseed oil is normal
Produced with mechanical expression method, be divided into two kinds of hot moulding and cold press.Hot moulding is to fry linseed to 120 DEG C or so, then enter by stir-frying
Row mechanical expression.Linseed oil fragrant odour made from hot moulding, but color is deeper, in yellowish-brown to black.Cold press is by flax
Seed is slightly handled at a temperature of less than 60 DEG C, then carries out mechanical expression.It is to utilize organic solvent energy dissolved oil that lixiviation process, which carries oil,
The property of fat, by moistening, permeating, the effect that molecule spreads, it will expect that the grease in embryo extracts, then again by oil and solvent
It is isolated the process of crude oil.In order to improve the extraction efficiency of grease and yield, in addition to solvent is added, ultrasonic wave is also used
Etc. supplementary means.Supercritical CO2Extraction process is to utilize CO2With the relation of density, i.e. pressure dissolves with temperature to supercritical fluid
Ability difference and carry out, because its operation temperature is low, no solvent residue, retain it is original active the advantages that and be widely used in
The extraction of grease.
Turn into a kind of new technology being widely studied recent years, oil extraction by enzymatic processing tool using enzyme-added method extraction grease type
There is oil yield high, oil colours pool is as clear as crystal, and the oil quality of extraction is good, and the extraction process consumption energy is low, and treatment conditions are gentle, operation
The advantages that safer, therefore had a wide range of applications in terms of grease extraction.The enzyme of oil extraction by enzymatic processing mainly has pectin
Enzyme, proteolytic enzyme, cellulase etc..Destruction of the enzyme to cell membrane, and the decomposition to lipopolysaccharides, lipoprotein, can increase
Refuel and expect mobility oily in tissue, so as to improve oil yield.Affinity difference and profit using non-oil component to oil and water
Proportion is different, is separated oily with non-oil component.
The research of the large oils of aqueous enzymatic extraction is a lot, and the research on extracting linseed oil by water-enzyme process is seldom.With
Linseed oil is increasingly welcome by consumer, and developing a kind of efficient, safe, economic linseed oil extracting method turns into urgently
The problem of to be solved.
Present invention optimizes the extraction and purification process of linseed oil, processes obtained linseed oil quality better, and VE contents are high,
Long-term consumption has the effect of improvement three is high.
