Abstract
The invention discloses a kind of methods that camellia seed kernel cold pressing produces tea-seed oil, are related to tea-seed oil production field;Fresh camellia oleifera fruit is coated with preservative film, saturated vapour pressure processing is put into, then shells, camellia seed kernel is immersed in inorganic agent, with being stirred by slow fire after drying, impregnated again with inorganic agent after stir-frying, finally use squeezer cold press fuel-displaced, after refined filtration, tea-seed oil is made;Organic solvent extract need not be added in extraction process, also high temperature need not be utilized to squeeze, tea-seed oil is squeezed out under conditions of low temperature is additive-free, the multiple nutritional components for remaining tea-seed oil are not destroyed, and tea-seed oil purity is high, yield is high, no objectionable impurities generates.
Description
Technical field:
The present invention relates to tea-seed oil production fields, and in particular to a kind of side of camellia seed kernel cold pressing production tea-seed oil
Method.
Background technology:
Tea-seed oil also known as camellia oil, tea pear oil, Wild camellia seed oil, camellia seed oil, tea oil seeds of trees oil.Camellia is Chinese big other
The ground specialty such as mountain, Fujian, Jiangxi, Hunan (Changning) can extract good camellia oil, i.e. tea-seed oil in fruit.Method one:Pressure
It squeezes.It is derived from the seed of tea oil tree.The manufacturing process of tea-seed oil can be divided into:Oil expression, filtering.Method two:Subcritical abstraction.It is subcritical
Low-temperature extraction technology is tea seed decladding, crushes, rolls embryo, subcritical low-temperature extraction, and finished product tea-seed oil is obtained after oil and fat refining.
Erucic acid, cholesterol, aflatoxins and other additives are free of in camellia seed oil.After tested:Insatiable hunger in camellia seed oil
Be up to 90% or more with aliphatic acid, oleic acid reaches 80-83%, and linoleic acid reaches 7-13%, and rich in protein and vitamin A,
B, D, E etc., the especially abundant leukotrienes contained by it are needed by human and cannot synthesize.The effect tea oil of camellia seed oil
It is the distinctive woody grease in China, aliphatic acid composition is similar to the best vegetable fat olive oil generally acknowledged in the world, there is " east
The laudatory title of square olive oil " contains several functions composition in tea oil, is eaten for a long time, and has the hardening of apparent prevention of cardiovascular, drop
The special efficacy of blood pressure, reducing blood lipid and other effects and cancer-resisting.
Currently, the preparation method that China produces camellia seed oil mainly has machinery pressure hot moulding method and solvent extraction method, squeezing method
Equipment is more, and fat residue rate is high, and conventional high-temperature hot moulding tea oil is easy that vitamin isoreactivity substance is made to be destroyed.Lixiviation process
Using 6# solvents, although having at low cost, the high advantage of oil yield, there are security risks for organic solvent, and the solvent discharged
Gas is unfriendly to environment.Therefore, how to research and develop and new squeeze technique so that can be effectively retained on the basis of additive-free
The nutritional ingredient of tea-seed oil, the problem of becoming urgent need to resolve.
Invention content:
Technical problem to be solved by the present invention lies in a kind of method for providing camellia seed kernel cold pressing and producing tea-seed oil,
Organic solvent extract need not be added in extraction process, need not also high temperature be utilized to squeeze, in the additive-free item of low temperature
Tea-seed oil is squeezed out under part, the multiple nutritional components for remaining tea-seed oil are not destroyed, and tea-seed oil purity is high, yield is high, nothing
Objectionable impurities generates.
The technical problems to be solved by the invention are realized using technical solution below:
A kind of method of camellia seed kernel cold pressing production tea-seed oil, includes the following steps:
(1) fresh camellia oleifera fruit is picked, one layer of preservative film is coated on camellia oleifera fruit surface, camellia oleifera fruit is put into 70 DEG C of vapor
60-90min is handled in saturated vapour pressure, naturally dry after cooling removes preservative film;
(2) tea seed after drying, which is sent into hulling machine, to shell, then is detached camellia seed kernel and shell with winnowing machine,
Collect camellia seed kernel;
(3) camellia seed kernel is immersed in inorganic agent the immersion 3-4h at 35-45 DEG C, 3-5 is cleaned with deionized water after immersion
It is secondary, it is put into curer and is dried at 55-65 DEG C;
(4) camellia seed kernel after drying is put into pot with being stirred by slow fire, camellia seed kernel quality is added during stir-frying
0.05% salt, stir-fry 3-5min, natural cooling;
(5) camellia seed kernel after cooling that will stir-fry crushes, and crosses 10 mesh sieve, is placed again into inorganic agent and is impregnated at 35-45 DEG C
