Description
Technical field
The invention belongs to food processing technology fields, are related to a kind of nano-emulsion liquid prepared by perilla herb oil or linseed oil
System and preparation method.
Background technique
Perilla herb oil rich in nutrition content does not contain only the fat-soluble functional component such as vitamin E, phytosterol, squalene, and so far
The highest vegetable oil of alpha-linolenic acid content found until the present has the function such as apparent antibacterial, antiallergy, anti-aging, reducing blood lipid
Energy.In addition to this, the volatile materials such as perillaldehyde, limonene contained in perilla herb oil assign its unique faint scent, increase to food
Taste plays an important role.Alpha-linolenic acid content is 53% in linseed oil, and alpha-linolenic acid is essential fatty acid, in human body
It can be converted into eicosapentaenoic acid and docosahexaenoic acid, they are the effective active composition in fish oil.Alpha-linolenic acid has anti-
The effects of tumour, antithrombotic, reducing blood lipid, nourishing brain cell, adjusting vegetative nerve, by more concern.
On the other hand, unsaturated fatty acid content is high in perilla herb oil and linseed oil, and a large amount of unsaturated fatty acid is easily
It is influenced by factors such as illumination, temperature, leads to the problem of oxidation deterioration, not only caused the loss of nutritional ingredient, also bring along flavor
Deterioration, to limit its application in food；And unsaturated fatty acid is macromolecular substances, and physiological absorption degree is poor,
It can not all absorb in vivo, cause the loss of nutritional ingredient.
Nanoemulsions by water, oil, surfactant and cosurfactant etc. spontaneously form the Thermodynamically stable formed,
Isotropism, transparent or semitransparent homogeneous dispersion system.Emulsion oil-in-water is that oil is passed through emulsifier as dispersed phase
Effect, is embedded in inside by water, so that starvation, delays to aoxidize, increases stability.
Summary of the invention
The purpose of the present invention is overcome the deficiencies of the prior art and provide a kind of nanometer prepared by perilla herb oil or linseed oil
The preparation method of emulsion system and the nanoemulsions, with the physiology for delaying perilla herb oil oxidation, improving perilla herb oil and linseed oil
Trap.
The present invention is to solve technical solution to adopt the following technical scheme that:
