Description
Technical field
The present invention relates to a kind of powdered oil and preparation method thereof, and in particular to one kind rich in middle low carbon acid powdered oil and
Its preparation method, belong to feed processing technology field.
Background technology
At present, with the development of feed manufacturing and cultivation industry, and the enhancing of Animal nutrition and epidemic preventive awareness, it is desirable to raise
Contain some special nutrient compositions in material, have excellent flavor, using convenience, storage-stable and to animal physiological and regulation work(
Important function can be produced, the functional nutrient feed of " herbal cuisine is homologous " is realized, by the favor of people.
Grease is the necessary nutrition of animal and energy substance, there is provided body necessary aliphatic acid, vitamin E, heat energy etc., but liquid
Body oil is using above there is the shortcomings that comparison is more, it is not easy to which water, exposure are easily oxidized in atmosphere, it is difficult to and Partial Food mixes
Close uniform.Therefore, people begin one's study and have developed powdered oil, powdered oil is oil made of the technology using microcapsules
Fat prod, not only stability is very high, shipping storage be also convenient for it is simple, be not easy to be aoxidized by oxygen in air.
Powdered oil foreign countries start from the fifties, have deeply been grown a lot with the progress and research of science and technology.Japan exists
There is advanced production technology in terms of powdered oil investigative technique, liquid oil and fish oil are mainly made into powdered oil, prevent oil
Lipid oxidation goes bad, while also reduces the storage cost of grease.
The nineties, China start to research and develop powdered oil.2005, stone swallow and Li Jihua of Jiangxi agricultural university et al. were carried out
Dietary fiber is made the Experimental Research of powdered oil, make dietary cellulosic not soluble in water that powdered oil be made, can be preferably
Human consumption can be helped.University Of Nanchang Li Chunli in 2007 etc. has carried out the experiment of anti-acid powdered oil, research and inquirement
Numerous emulsifiers dosage and core, wall material influence after, spray-dried to be made acidproof powdered oil, clad ratio is up to 90%
More than.2008, Chen Bin was prepared for being added in the powdered oil among bread pre-add powder, the pouch as condiment for instant noodles
Dress, allows dusty yeast and powdered oil to add together in this pre-add powder, facilitates the foaming of bread and keeps the complete of nutrition,
Make preferable bread.High red sun in 2011, Zheng Lianhe etc. are using cold pressing coconut oil as core, using emulsification and spray drying
The method of being combined prepares coconut oil powdered oil.
Powdered oil disclosure satisfy that the needs of a variety of processing, and its application field is also more and more extensive.Because powdered oil
Water-soluble and emulsibility is relatively good, is also not easy to be aoxidized by the oxygen in air, and stability is very high, and cost of transportation is also low, storage
Deposit and be also convenient for.
Ester exchange reaction is one of method for producing powdered oil.Just had been widely used early in the 1950s, be
The composition of oil fatty acid and glyceride, structure, property is set to change and there is the important method of brand new.Ester exchange makes grease
Be modified and there is raciness, isomers is few, aliphatic acid composition is constant and do not produce trans acids, better nutritivity can be produced
The fat of value.
At present, ester ester exchange has the country such as enzymatic and chemical modification, Japan, Britain, Denmark to there has been among palm oil
Fraction leach-s/tive is the production that raw material is enzymatically modified extraction of cocoa butter.In recent years, the distinctive oil resource-oleum sapii in China and
Enzymatically modified cacaolike butter processed there has also been more research to tea-seed oil.But carry out ester ester friendship using Glycerin, mixed triester with caprylic acid capric acid and coconut oil
Change and manufacture the grease of desirable trophic function and physical characteristic there is not been reported.
The triglycerides that the pungent sweet ester of capric acid is made up of the aliphatic acid of 8~10 carbon atoms, belongs to middle carbochain（Carbon number
For 6~12 fatty acid triglycercide）Fatty acid ester, abbreviation MCT.MCT confirms as GRAS materials through FDA, the pole in enteron aisle
Facile hydrolysis, absorb, 4 times faster than general grease of infiltration rate, and do not accumulated in liver and body.It can exist as fat substitute
Body absorption accretion rate is fast, available for adjusting fat metabolic disturbance, and can reduce cholesterol, high but also as prevention and treatment
The medicine of blood fat and fatty liver.National food safety standard（GB 2760-2011）Provide that the sweet ester of pungent capric acid can be used for beverage, ice
It is unlimited to swash industry, the highest usage amounts such as icepro, candy, chocolate, hydrogenated vegetable oil.
Phosphatide is human body cell（Cell membrane, nuclear membrane, plastid film）Basis, and have to work(such as nerve, reproduction, hormones
Important relationship, there is very high nutritive value and medical value.Countries in the world start phosphatide food heat, and person in middle and old age are in order to prevent
With treatment modern disease, particularly prevent senile dementia, numerous women are beauty and fat-reducing, and children and adolescent student are strong
The needs of brain intelligence development, extensive human consumption soybean phosphatide.The U.S. claims the most important nutritious subsidy product that phosphatide is exploitation in nearly 30 years,
Japanese then someone claims phosphatide to be generated based on modern medicine, pharmacy, nutritional knowledge *, is biochemical reaction process in human body
In can most play the material of useful effect, by the favor of people.
The content of the invention
The purpose of the present invention is overcome the deficiencies in the prior art, there is provided one kind is rich in middle low carbon acid powdered oil and its preparation
Method.This method uses enzymatic or chemical ester ester exchange modification technology using pungent capric acid glyceride with coconut oil, produces nutriture value
Value, the special modified grease based on middle low carbon acid of feature.Modified grease is adjusted with nutritional agents and emulsifying agent-soybean lecithin
Matter, then by mixing water made of core modified grease liquid addition wall material stabilizer quenched with phosphatide, emulsifying agent and other auxiliary materials
In system, then after emulsifying, oil-in-water type is made（O/W）System, the powder being processed into using microcapsules spray drying technology
Powder oil product.So as to impart many new characteristics of product, have higher energy and trophic function is rich in octanoic acid, capric acid
