Abstract
A kind of preparation method of camellia oil, include the following steps: to produce tea seed kernel and rice bran mixture, tea seed is dried, is cleaned, is shelled, selects excellent impurity elimination, curing, the rice bran fried is added and stirs evenly, mixture is obtained, wherein rice bran and the tea seed kernel weight ratio after curing are 1:5-10;Then by squeezing twice, obtained camellia oil content of phytosterol is high, and quality is high.
Description
Technical field
The invention belongs to agricultural technology fields, and in particular to a kind of camellia oil that content of phytosterol is high and its preparation side
Method.
Background technique
Vegetable oil is one of content of phytosterol food more abundant, is white powder, can also have ester shape to be dissolved in grease,
Phytosterol is divided into 4- demethlyate sterol, 4- methylsterol and 4,4 '-dimethylsterols three classes, and demethlyate sterol mainly has Β-
Sitosterol, stigmasterol, campesterol and brassicasterol etc. are primarily present in the structure of phytosterol and animal in the seed of plant
The structure of property sterol is substantially similar, is uniquely a difference in that the difference of c-4 connected number of methyl groups and c-11 side chains, exactly this
Small different causes on a little side chains make it have various physiological functions.
Phytosterol is used for the heart disease of prophylactic treatment coronary atherosclerosis class, to treatment ulcer, Skin Squamous Cell Carcinoma, palace
Neck cancer etc. has apparent curative effect;In addition, phytosterol is also important the raw materials for production of steroid drugs and vitamine D3.Plant steroid
Alcohol has good antioxidant, can make food additives (antioxidant, nutritional additive);Also it is former to can be used as growth of animal agent
Material promotes growth of animal, promotes animal health.
What content of phytosterol was minimum in vegetable oil is camellia oil, content be only 110mg/100g or so namely content only
It is 0.1% or so;And content is 4.5-6.5% in rice bran oil, in order to improve content of phytosterol in tea oil, keeps its nutrition balanced,
Rice bran can be added to extract oil together.
Summary of the invention
There is provided it is an object of the invention to overcome the deficiencies in the prior art a kind of camellia oil that content of phytosterol is high and
Preparation method.
The technical scheme is that a kind of preparation method of camellia oil, in turn includes the following steps:
(1) tea seed kernel and rice bran mixture are produced: tea seed being dried, is cleaned, is shelled, selects excellent impurity elimination, curing, addition fries
Rice bran stir evenly, obtain mixture, wherein rice bran and curing after tea seed kernel weight ratio be 1:6-11;Rice bran was added
Few, obtained oily content of phytosterol is low, and rice bran is added excessively, and oil production is low, and production efficiency is low;
(2) single pressing: the mixture that step (1) is obtained squeezes camellia oil sedimentation filtration into oil press, obtains oil cake;
(3) twice pressing: adding camellia oil into oil cake, obtains withered oil cake mixture, wherein making in withered oil cake mixture
Reach 25-30 mass % containing camellia oil;The crusher that withered oil cake mixture is put into after an other preheating is squeezed, is filtered
To camellia oil and filter residue;
Curing described in step (1) is that parch curing is carried out to tea seed kernel, and parch temperature is 130-150 DEG C, tea seed kernel moisture control
For system in 3-5 mass %, tea seed kernel color is changed into yellow or yellowish-brown from faint yellow.
Step (2) is that the mixture for obtaining step (1) is cooled to 50-80 DEG C, is squeezed into oil press.
Camellia oil is added excessive in step (3), be easy to cause waste, and addition is very few, and the moist degree of rice bran is inadequate, wherein
Oil yield it is low.
Need to carry out water before traditional rice bran oil expression and steam moisture absorption, finally to carry out heating aquation dehydration, nutrition therein at
Phosphatide is divided also to be deviate from, and the rice bran oil after aquation is apt to deteriorate, rice bran oil is squeezed in camellia oil and formed by the method for the present invention
Ready-mixed oil not only simplifies the milling process of rice bran oil, also adds the content of phytosterol in camellia oil, keeps its nutrition balanced.
The method of the present invention further includes following steps:
(4) it cleans: including stirring growing the grain, being filtered to remove crystal, it is specific as follows: the camellia oil that step (3) obtains is cooled to 5-8
DEG C, stirring, speed of agitator 20-30r/min keeps stirring 24-30h at this temperature;Then -10--5 DEG C are cooled to, is stirred
Growing the grain is mixed, speed of agitator 5-10r/min keeps growing the grain 5-9h at this temperature, precipitates crystal;It is filtered to remove crystal;Obtain mountain
Tea oil.
The filter residue that step of the present invention (3) obtains, the weight with camellia oil can also be added during step (4) stirring growing the grain
The camellia oil purity is high obtained than the tea seed cake for 1-2:100, is added, the crystal of precipitation have BaP, wax, colloid, moisture and
It is wrapped in the harmful substances such as heavy metal therein, pesticide residue, protein, cellulose.
The method of the present invention further includes following steps:
(5) filling: nitrogen charging is filling.
The invention also includes the camellia oil that above method is prepared, content of phytosterol 300-400mg/100g.
