Description
Technical field
The present invention relates to the use of high valent acid vegetable oil and produce the preparation method being rich in plant sterol ester biodiesel, specifically relate to
And utilize high valent acid vegetable oil to be raw material, by the side rich in plant sterol ester biodiesel for the lipase-catalyzed esterification method one step preparation
Method, belongs to oils and fatss deep processing and higher value application field.
Background technology
Normal vegetable oil its acid value typically ratio producing is relatively low, but in particular cases, such as in oil plant, moisture is high, preserve not
When and processing in play the role of enzyme etc., lead to the acid value of lipids produced higher, wherein have high acid value Semen Tritici aestivi than more typical
Germ oil and high acid value Testa oryzae oil.High acid value oils and fatss are primarily referred to as the oils and fatss that acid value is more than 20mgkoh/g.The generation of high acid value oils and fatss
Not only its Fatty acid compositions is more reasonable for table Testa oryzae oil, and containing abundant oryzanol, Squalene, ve (tocopherol, life
Educate trienol), the various active material such as sterol, therefore there is enhance immunity, reduce cholesterol, adjust blood fat, prevent tremulous pulse
The physiologically active such as atherosis, is described as " nutrition oil " by nutritionist, is a kind of ideal edible oil and fat.Contain in Testa oryzae and live
Property higher lipolytic enzyme, lead to the free fatty acid content in Testa oryzae oil higher, typically more than 10%, some even exist
Between 30%-40%.At present, high acid value oils and fatss be mainly used in deacidification become low acid value oils and fatss, preparation biodiesel and fatty acid etc..
High acid value oils and fatss carry out deacidification according to conventional grease acid stripping method and can have that environmental pollution is serious, energy consumption big, neutral fat yield
Low problem.Testa oryzae oil acid number can be reduced to regulation and require by traditional alkali-refining deacidification method, but alkali refining makes paddy in Testa oryzae oil
The nutritional labelings such as dimension element run off in a large number, simultaneously as soap is carried secretly and inevitable fat saponification to the emulsifying of oils and fatss, serious shadow
Ring oil and fat refining yield.With the development of biotechnology, this reaction condition of zymotechnic is gentle, the novel process of high catalytic efficiency
Technology causes the attention of related scholar.Being used at present relatively broad is to be as acyl acceptor using glycerol or monoglyceride
Esterifying agent, occurs esterification to reach the purpose of deacidification with free fatty.
The physiology such as plant sterol ester not only remains plant sterol reduction cholesterin and regulating blood-fat, antiinflammatory is brought down a fever, anticancer are lived
Property, also have preferably fat-soluble, in oils and fatss or containing the application more broad range in fatty foods.In addition, plant sterol ester
Absorption rate be 5 times of plant sterol, and there is more preferably Lowering cholesterol effect, be a kind of new functional food base
Material.2010, plant sterol ester was listed in new food resource by China's Ministry of Public Health.
The present invention is using plant sterol as dissociating in acry radical donor and the high-acid value grease such as Testa oryzae oil or Semen Tritici aestivi germ oil
There is enzymatic esterification in fatty acid, on the one hand can substantially reduce the acid value of high-acid value grease, on the other hand can generate new
Functional active components plant sterol ester, may finally obtain the biodiesel rich in plant sterol ester.At present, carry out both at home and abroad
The report of plant sterol ester study on the synthesis is more, but is not yet related to high-acid value greases such as peracid value rice bran oil, Semen Tritici aestivi germ oils
For raw material, the research report rich in plant sterol ester biodiesel for the preparation.
Content of the invention
It is an object of the invention to provide a kind of utilization high valent acid vegetable oil produces rich in plant sterol ester biodiesel
Method, the acid value of high-acid value grease (Testa oryzae oil etc.) can substantially drop in the method one side, on the other hand can generate new function
Active component plant sterol ester, product need not assist and isolate and purify, easy and simple to handle.
For achieving the above object, the technical solution used in the present invention is as follows: a kind of rich using high valent acid vegetable oil production
