Description
Technical field
The present invention relates to a kind of edible blend oils, and in particular to a kind of high stability plant blend oil rich in DHA and its
Preparation method.
Background technology
DHA (docosahexaenoic acid) is a kind of to be distributed in the long-chain omega-fatty acid of human body everywhere.More particularly, it goes back
It is brain and the main composition fat of eyes and the important component of heart.The data constantly accumulated shows DHA in life
Safeguard that health plays very important role in each stage.
Human body maintains the normal function of various tissues, it is necessary to assure there are sufficient various aliphatic acid, it can if lacking them
Cause a series of symptoms, including growth retardation, the skin abnormality scales of skin that peel off, dysnoesia etc..DHA is as a kind of required fat
The effects that acid, enhancing memory is with thinking ability, raising intelligence, is more notable.Population epidemiology is the study found that DHA contains in vivo
Measure that the Psychological Endurance of high people is relatively strong, mental development index is also high.
With scientific and technical personnel to DHA's the study found that due to its active character make its exposure in air quickly occur from
Dynamic oxidation is rotten, or even generates fishlike smell, to influence product mouthfeel and nutritive value.To solve the problems, such as this, conventional oil is added
The common antioxidant such as fat, vitamin E or vitamin C or anti-oxidant auxiliary agent, still, antioxidant effect is general, moreover,
Want the ready-mixed oil of raw material based on DHA and common plant grease, it is with single nutrient component, Fatty acids composition is unreasonable, it is more difficult to by people
Body fully absorbs, and effect is not obvious in terms of intelligence development.
Invention content
In view of the above technical problems, the present invention provides a kind of rich in the high stability plant blend oil of DHA and its preparation
Method.
Technical solution is used by the present invention solves the technical problem：A kind of high stability plant reconciliation rich in DHA
Oil includes the raw material of following weight percent：DHA0.5~1.2%, strange Asia seed 20~30%, grape pip 20~30% are red
Flower seed 10~20%, peony seeds 10~20%, tea seed 10~20% and seabuckthorn seeds 10~20%.
The present invention solves another technical solution used by the technical problem：A kind of high stability plant rich in DHA
The preparation method of ready-mixed oil, includes the following steps：
First, according to weight ratio by the strange sub- seed 20~30%, grape pip 20~30%, kardiseed 10~20%,
It is added to multistage point after peony seeds 10~20%, tea seed 10~20% and the drying of seabuckthorn seeds 10~20%, mixing and crushing
From supercritical CO2In the extraction kettle of extraction equipment, extractant condition, 40~50 DEG C of extraction temperature, extracting pressure 32- are adjusted
40MPa, 2.5~5.0h of extraction time enter the decompression separation for carrying out carbon dioxide and grease in separating still, adjust after the completion of extraction
The process conditions of separating still are saved, 40~60 DEG C of I temperature of separating still, I 10~18MPa of pressure of separating still obtain plant from separating still I
Ready-mixed oil crude oil；
Then plant blend oil crude oil is refined：The plant blend oil crude oil of extraction gained is added to molecule
It distills in sample jar, adjusts molecular distillation technological parameter, 3~7Pa of vacuum degree, 110~130 DEG C of vapo(u)rizing temperature, knifing rotating speed 120
~240rmin-1, 40~60mLmin of charging rate-1And 30~40 DEG C of condensation temperature, carry out refining treatment, refining process
After the completion, the DHA that the plant blend oil after refining mixes the weight ratio is collected, the high stability for being rich in DHA is both obtained
Plant blend oil.
Compared with prior art, there is following good effect：The high stability plant blend oil rich in DHA of the present invention,
By adding the higher strange sub- seed oil of inoxidizability, grape seed oil, safflower seed oil, peony seed oil, camellia seed oil and Seabuckthorm Seed Oil,
Effective protection DHA is not oxidized, avoids generating bad eating mouth feel and fishlike smell；Wherein, strange sub- seed oil is rich in flavonoids antioxygen
Compound, such as chlorogenic acid, caffeic acid, myricetin not only itself have and remove free radical, prevent unsaturated fatty acid peroxidating
The effects that, more can preferably it be acted on ω -3 Coordinated Plays of DHA.In addition, grape seed oil, safflower seed oil, peony seed oil, oil tea
Seed oil and Seabuckthorm Seed Oil, not only be rich in various nutritional ingredients (vitamin E, phytosterol, minerals etc.), but also rich in oleic acid,
The unsaturated fatty acids such as linoleic acid plus linolenic acid, have greatly enriched the nutritive value of the plant blend oil of the present invention, and collocation is more closed
Reason, it is easier to it is fully absorbed by human body, it is better in terms of intelligence development.
With reference to embodiment, the invention will be further described.
