Description
Technical field
The present invention relates to microbial grease and vegetable fat field, be specifically related to a kind of vegetable seed ready-mixed oil containing DHA algal oil and preparation method thereof.
Background technology
Protein, sugar and fat are the main greatly nutrients of the mankind three, indispensable.Aliphatic acid is again the key component of lipid, whether exists according to double bond, point saturated fatty acid and unrighted acid; According to the position of double bond from methyl end, be divided into again the unrighted acids such as ω-3, ω-6, ω-9.
People will take in fat every day, fat is not only the Ministry Of Fuel And Power power source of body cell, and have close relationship with the growth of human body cell and decline, particularly polyunsaturated fatty acid (polyunsaturated fatty acid, PUFAs) is the constituent of human body cell and various tissue and participates in multiple metabolism.DHA gains great popularity because it is described as " docosapentaenoic acid " to the specific function of human body by scientist.Develop DHA resource and become one of popular direction of the researchs such as whole world biologist, nutritionist, grease scholar, medical scholar.
Although the DHA in deep sea fish oil also derives from algae, containing the carcinogen such as bioxin, biphenyl in fish oil, and have a fish like smell, cause the very high or quality of purifying cost can not be up to standard.And utilize the DHA of Production by Microorganism Fermentation, there is the advantages such as aliphatic acid composition is simple, DHA content is high, pollution-free chemical substance.At present, DHA is mainly used in baby formula milk powder and food, and general population not yet has the approach being convenient to take in DHA in diet.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of containing the vegetable seed ready-mixed oil of DHA algal oil and the preparation method of this vegetable seed ready-mixed oil, this vegetable seed ready-mixed oil is with rapeseed oil, palm oil, corn wet goods is as base oil, add DHA algal oil, the vegetable seed ready-mixed oil be mixed with is containing DHA, and the saturated fatty acid (SFAs) containing proper ratio, monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acid (PUFAs), make general population can take in the DHA of aequum when edible, and take in the SFAs of proper ratio, MUFAs and PUFAs, and this vegetable seed ready-mixed oil has good stability and longer shelf life.The technical scheme adopted is as follows:
A vegetable seed ready-mixed oil containing DHA, is characterized in that the component containing following weight proportioning: DHA algal oil 1.37-2.74%, rapeseed oil 49.50%, palm oil 19.32-20.69%, corn oil 25.94%, linseed oil 2.5%.
In preferred version, the above-mentioned vegetable seed ready-mixed oil containing DHA contains the component of following weight proportioning: DHA algal oil 2.06%, rapeseed oil 49.50%, palm oil 20.00%, corn oil 25.94%, linseed oil 2.5%.
After being mixed by DHA algal oil, rapeseed oil, palm oil, corn oil and linseed oil five kinds of oil products according to the above ratio, be deployed into the vegetable seed ready-mixed oil containing DHA.
Above-mentioned DHA algal oil, rapeseed oil, palm oil, corn oil and linseed oil all can commercially buy.Such as:
The DHA algal oil that DHA algal oil can adopt fermentation method to produce, algae kind used is the hidden dinoflagellate of Kou Shi, split kettle algae etc. (as the DHA algal oil that Guangdong Runke Bioengineering Co., Ltd.'s fermentation method is produced, algae kind used is for splitting kettle algae), this DHA algal oil meets the standard-required of GB26401-2011, safe, nontoxic.In preferred above-mentioned DHA algal oil, DHA content is 35-45% (weight).
The rapeseed oil adopted meets standard-required (the milt refining one-level rapeseed oil as imperial in commercially available gold of GB1536-2004, benefit Hai Jiali food marketing Co., Ltd produces), its mid-oleic is 45.5 ~ 47.7% (weight), and linoleic acid content is 14.87 ~ 17.02% (weight).The nutritional labelings such as rapeseed oil is rich in oleic acid and linoleic acid, its unrighted acid can be absorbed by body well, have certain softening blood vessel, delay senility effect; Rapeseed oil contains certain seed phosphatide, very important to the growth of blood vessel, nerve, human brain; The cholesterol of rapeseed oil seldom or hardly contains, so be afraid of that the crowd of cholesterol also can relievedly eat.Frequent edible rapeseed oil, can prevent wrinkled skin aging, and protection vascular wall, prevents thrombosis, contributes to prevention of arterial sclerosis and coronary heart disease, improves the memory of human brain, delay brain function decline.
The palm oil adopted meets the standard-required (as the palm oil that beneficial Hai Jiali (Wuhan) cereal and oil industry Co., Ltd produces) of GB15680-2009, and wherein palmitic acid content is 41.5-43.7% (weight).
The corn oil adopted meets standard-required (the fish corn oil as imperial in commercially available gold of GB19111-2003, benefit Hai Jiali food marketing Co., Ltd produces), containing the unrighted acid of more than 80%, its mid-oleic is 28.0-34.2% (weight), and linoleic acid content is 48.0-56.5% (weight).Corn oil is containing oleic acid and linoleic acid, be easy to human consumption and absorption, the function reducing body's cholesterol, hypotensive, softening blood vessel, increase human muscle and heart, cardiovascular system can be played, prevent and improve artery sclerosis, reduce the effects such as heart disease generation, and the outbreak of human prostate's illness and the generation of dermatitis can be alleviated.
The linseed oil adopted meets the standard-required of DB64/673-2010, and wherein linolenic acid content is 52.8-53.2% (weight).Alpha-linolenic acid content in linseed oil is higher, belonging to ω-3 is polyunsaturated fatty acid (ω-3 polyunsaturated fatty acids), appropriate interpolation linseed oil, can make the composition of SFAs, MUFAs and PUFAs in vegetable seed ready-mixed oil, and in polyunsaturated fatty acid, the composition of ω 6/ ω 3 meets desirable recommendation more.
The present invention also provides a kind of preparation method of above-mentioned vegetable seed ready-mixed oil, it is characterized in that comprising the steps: successively
