Description

A kind of Alpha-ethyl linolenate microemulsion and preparation method thereof
Technical field
The present invention relates to Alpha-ethyl linolenate microemulsion, more particularly to a kind of Alpha-ethyl linolenate microemulsion and its preparation side Method belongs to chemical field.
Background technology
Alpha-linolenic acid (α-Linolenic Acid, abbreviation ALA）, scientific name：Allcis-9,12,15-Oc-tadecatrienoic acid, It is a kind of advanced polyunsaturated fatty acid, it is that constitute the important substance and Ω -3 of brain cell and retina be unsaturated lipid The parent of fat acid, by its metabolizable generation eicosapentaenoic acid needed by human（EPA）, clupanodonic acid（DPA）, 20 Two carbon acids（DHA）Three big trophic factors, therefore, alpha-linolenic acid are indispensable nutritional factors in health, and belonging to must Aliphatic acid is needed, however, it is unable to Synthesis in human body, it is necessary to be supplemented by being absorbed in food, supplement this nutrition daily Ingredient has particularly significant effect to health.
Scientific investigations showed that alpha-linolenic acid has reducing blood lipid, blood pressure lowering, antiallergy, antithrombotic, protection eyesight, prevents inflammation Disease increases brain cell substance, improves the effects that memory.Human body lacks alpha-linolenic acid for a long time, and Human Lipid Metabolism can be caused disorderly Disorderly, the symptoms such as immunity reduction, hypopsia, decrease of memory, artery sclerosis are caused to occur, due to general in population of China diet All over alpha-linolenic acid is lacked, causes the cardiovascular and cerebrovascular diseases number such as China's hyperlipidemia and hypertension to increase, directly affect people's Health, for this purpose, the products such as the health products and nourishing additive agent of exploitation rich in alpha-linolenic acid and its derivative are imperative 's.However, alpha-linolenic acid is oxidizable rotten under air, light and heating state, to improve its stability, currently, in the market Existing health products containing alpha-linolenic acid mainly occur with capsule and emulsion form, as 105707568 A of Chinese patent CN are disclosed " a kind of alpha-linolenic acid soft capsule and preparation method with auxiliary lipid-lowering function " passes through microencapsulation form and improves α-flax Absolute acid stability, but it is more due to the use of auxiliary materials such as glycerine, gelatin, to increase liver metabolism burden, moreover the price mesh of capsule It is preceding relatively high.For another example Chinese patent CN104957622 A disclose " one grow flax stable emulsion and preparation method thereof " and pass through The manufactured stable emulsion after emulsification such as protein, flavoring agent, stabilizer or antioxidant is added after flax instant powder is dissolved, Since flax instant powder is using linseed as made of Raw material processing, alpha-linolenic acid content is low, is actually in the breast of less stable Liquid is easily layered, is oxidized easily after layering, and is not easy to the absorption of human body stomach.In order to improve alpha-linolenic acid utilization rate, α-is expanded Leukotrienes application range, it is necessary to carry out Alpha-ethyl linolenate microemulsion and preparation method research.
Microemulsion be two kinds of immiscible oil are formed into Thermodynamically stable with water under Action of Surfactant, appearance is in Transparent or semitransparent, stable homogeneous system of the grain size between 1-100nm, the system is with good stability and dispersed. And the grain size of common emulsion is larger and be unevenly distributed, usual grain size is more than 100nm, and the system is unstable.Microemulsion system Because grain size is smaller, stomach can be convenient for drug absorption, drug effect and utilization ratio of drug is improved and be applied to doctor as pharmaceutical carrier Medicine field.The key technology that microemulsion is formed is found between suitable surfactant and oil phase, water phase and surfactant Proportioning, the microemulsion stability and dispersibility that suitable surfactant and good compatibility are formed is more excellent.China Disclose a variety of other microemulsions in patent application, for example, disclosed in Chinese Patent Application No. 2016111343095 it is a kind of micro- Lotion and preparation method thereof, a kind of water in oil microemulsion detergent for ink disclosed in 2016108448443 and preparation method thereof Deng.But the component selection and compatibility in these microemulsions are not suitable for Alpha-ethyl linolenate microemulsion, seek to develop α-flax Acetoacetic ester microemulsion is the effective way for expanding its application.
Invention content
It is an object of the invention to overcome the above problem present in current Alpha-ethyl linolenate microemulsion preparation, provide A kind of Alpha-ethyl linolenate microemulsion and preparation method thereof.
To achieve the purpose of the present invention, following technical solutions is used：A kind of Alpha-ethyl linolenate microemulsion, including α- Ethyl linolenate or oil phase, surfactant water containing Alpha-ethyl linolenate, also contain cosurfactant, the microemulsion The parts by weight of middle each component are as follows：4-70 parts of Alpha-ethyl linolenate；6-40 parts of surfactant and cosurfactant；It is inorganic 0-1.5 parts of salt；0.1-1.5 parts of antioxidant, surplus are water, Alpha-ethyl linolenate Alpha-ethyl linolenate or purple perilla after purification It is detached after oil and the ethyl esterified perilla herb oil or linseed oil and ethyl alcohol esterification that isolate and purify rear gained after ethyl alcohol esterification pure The ethyl esterified linseed oil of gained after change；The surfactant is Tween80, and cosurfactant is salicylic acid；Further 's；Tween80 and salicylic mass ratio are 10 in the complexed surfactant:1 ；Further；The inorganic salts For sodium chloride or sodium bicarbonate or sodium carbonate, the antioxidant is ascorbic acid or vitamin E or tea polyphenols or dibutyl The combination of hydroxy-methylbenzene or butylated hydroxy anisole or tert-butyl hydroquinone or above-mentioned two of which.
A kind of preparation method of Alpha-ethyl linolenate microemulsion, above-mentioned each component and parts by weight proportioning, including it is following Step：
A：Accurately weigh required each component；
B：Heating temperature is controlled within the scope of 20-30 DEG C, by Alpha-ethyl linolenate or the oil phase containing Alpha-ethyl linolenate and antioxygen Then under slow stirring composition mixing oil phase after agent mixing adds surfactant and cosurfactant thereto, and It is allowed to uniformly mixed；
C：Under slow stirring, water or the water dissolved with inorganic salts are added in the mixed system that above-mentioned steps B is obtained, stirring is equal After even, obtain at this time clear, stable homogeneous nanometer micro-emulsion.
The present invention is with Alpha-ethyl linolenate or ethyl esterified perilla herb oil or ethyl esterified linseed oil, surfactant and helps surface Property agent, water constituent form a kind of stable homogeneous, clear grain size between 1-100nm microemulsion system, formed after measured Microemulsion is oil-in-water, can ensure that it is not oxidized in storage and use, since this microemulsion after dilution can be with Oil-in-water microemulsion characteristic is kept, so the microemulsion of the present invention can be present in the various beverages largely drunk with low concentration Among, the usage scenario of alpha-linolenic acid is expanded significantly, since concentration is low, cost will not be very high, and ordinary consumer can receive, Since this Alpha-ethyl linolenate microemulsion system stability is good, grain size is small and uniform, is convenient for the absorption of human body stomach, makes α-flax Acid absorption rate is high, is a kind of human body supplement effective approach of facility of alpha-linolenic acid to improve the utilization rate of its nutritional ingredient.Together When preparation process of the present invention it is simple, convenient for large-scale production so that the alpha-linolenic acid in microemulsion is protected and is made full use of.
