Description
Technical field
The invention belongs to oils processing technique fields, and in particular to a kind of clean preparation method of original flavor camellia oil.
Background technique
Camellia oil also known as tea oil, tea-seed oil, camellia seed oil are derived from the seed of Camellia Theaceae tea oil tree.Camellia oil
In be free of erucic acid, cholesterol, while unsaturated fatty acid is up to 90% or more in camellia oil, oleic acid reaches 80-83%, and linoleic acid reaches
To 7-13%, and rich in protein and vitamin A, B, D, E etc., the especially linolenic acid abundant contained by it be it is needed by human and
Cannot synthesize again, furthermore in camellia oil also contain camellianin, tea polyphenols, saponin, tannin, and rich in antioxidant and have disappear
The squalene of scorching effect, and squalene and Flavonoid substances play the role of to anticancer it is splendid.Camellia oil, which has, remains cardiovascular
System improves the immunity of the human body, and reduces cholesterol, prevents and treats hypertension, clearing away heat and eliminating dampeness, desinsection removing toxic substances, clearing stomach ease constipation etc.
Function.
The preparation method of existing camellia oil mainly has more mature mechanical pressing method in production, solvent extraction method, overcritical
Fluids extraction, and producing for China's camellia oil generally takes mechanical pressing method and solvent extraction method, mechanical expression can divide again
It is squeezed for high temperature machine and low temperature machine squeezes, it is deep that high temperature machine squeezes camellia oil color, and makes trans-fatty acid and 3, the production of 4- BaP
Raw probability increases, and high temperature is easily destroyed the effective components such as tocopherol, squalene, sterol in camellia oil, to seriously affect
Camellia oil quality；However low temperature machine squeezing production efficiency is low, can take a small amount of saponin out of into oil, easily forms muddy state,
And saponin sense of taste is bitter, pungent, and consumption is poor, it is difficult to reach the requirement of respective country standard；The essence of existing camellia oil simultaneously
Refining is directly connect in production using chemical substance with camellia oil frequently with techniques such as phosphoric acid degumming, caustic soda depickling, activated decolorations
Touching, be easy to cause secondary pollution, there are the hidden danger of food safety and sanitation.
Summary of the invention
In view of the above deficiencies, the present invention provides a kind of clean preparation method of original flavor camellia oil, lower squeezing is controlled
Temperature, and carry out without using chemical reagent the refining of camellia oil solves in camellia oil during effective component is easily destroyed and produces
Chemical substance directly contacts the problem of causing secondary pollution with camellia oil.
The present invention is achieved by the following technical scheme:
A kind of clean preparation method of original flavor camellia oil comprising following steps:
(1) processing of camellia oleifera fruit: the camellia oleifera fruit of picking is screened, and is selected mature camellia oleifera fruit and is impregnated 20~30 in lye
Minute, then with clear water rinse 2~3 times, then camellia oleifera fruit is dried 30~40 minutes at 80~90 DEG C, then by camellia oleifera fruit into
The conventional shelling of row obtains tea seed；Because of the easy to carry various moulds in the surface of camellia oleifera fruit, the present invention uses dipping by lye
Camellia oleifera fruit can effectively kill mould, prevent mould to be brought into subsequent step and be infected with tea seed or camellia seed kernel, so as to cause
The mildew of tea seed or camellia seed kernel, while camellia oleifera fruit is dried into reduction moisture content, mildew is reduced, but also the pericarp of camellia oleifera fruit
Cracking is convenient for shelling peeling；
(2) processing of tea seed: by tea seed obtained in step (1) carry out selection by winnowing deviate from ghost, then by tea seed according to
Particle size is divided into three-level, and the partial size of first order tea seed is greater than or equal to 30mm, and the partial size of second level tea seed is greater than 20mm
And it is less than 30mm, the partial size of third level tea seed is less than or equal to 20mm, then successively by first order tea seed, second level oil tea
Seed, third level tea seed are sent into the tea seed that color selector carries out color sorting removing mildew, then by first order tea seed, second level oil tea
Seed, third level tea seed are sequentially placed into pair roller type decorticator and peel off, and obtain camellia seed kernel of the shell-containing rate less than 5%, will be each
It is cleaned, is then crushed in crusher, then by oil tea after the camellia seed kernel mixing obtained after grade shelling camellia seeds
It is 15% that seed benevolence, which is air-dried at room temperature to moisture content, then camellia seed kernel is carried out microwave baking, the tiling thickness of camellia seed kernel
For 2~5cm, stoving temperature is 60~90 DEG C, and the power of microwave is 50~120KW, and moisture content is obtained after microwave baking
For 4~6% camellia seed kernel；When first reducing moisture content using the mode of air-drying, then carrying out microwave baking drying and can reduce baking
Between, avoid the heating of long-time microwave baking to the destruction in tea seed vulnerable to thermal metamorphism ingredient；
(3) cold pressing: by the camellia seed kernel handled by step (2) microwave baking 60~80 DEG C at a temperature of carry out
Squeezing, the oil after squeezing obtain crude oil after oil filter is filtered；
(4) physics refines: crude oil obtained in step (3) being placed in adsorption moisture and ionized impurity in high-voltage electrostatic field, is being stirred
Under the conditions of mixing, 30KV is boosted to uniformly with the speed of 1.5~2KV/S, prevents electric current from may not exceed 2A, constant pressure 0.5~2 hour,
Then 35-38KV is uniformly boosted to according to the speed of 0.5~1.0KV/S, prevents electric current from may not exceed 2A, constant pressure 0.5~2 hour
Afterwards, it separates except obtaining original flavor camellia oil after water content in oil and ionized impurity.
Further, it according to mass ratio is (0.5~1) that the lye in above-mentioned steps (1), which is with food grade sodium hydroxide and water:
100 ratio is mixed to get.
Further, in above-mentioned steps (2), the charging rate of first order tea seed color sorting is 15~20 per second, second
The charging rate of grade tea seed color sorting is 20~30 per second, and the charging rate of third level tea seed color sorting is per second 30~40
Grain.
Further, the frequency of microwave is 2400~2500MHz in above-mentioned steps (2).
Further, the mixing speed in above-mentioned steps (4) is 30~100r/min.
The technical program has the advantages that compared with prior art
1, the present invention carries out low temperature oil expression using mechanical system, and this using Electrostatic Absorption water content in oil and separation ionized impurity
The method of physical removal impurity does not use chemical solvent, on the one hand avoids chemical substance caused by due to using solvent extraction residual
Problem is stayed, destruction of the excessive temperature to nutritional ingredient is on the other hand avoided, so that production obtains the original flavor camellia oil of high-quality；Together
When high pressure be divided into two pressure stages when separating and carry out, be conducive to the absorption of water content in oil and ionized impurity, be easy to use physics
Method separate removal.
2, tea seed is being pressed grain size grading by the present invention, and suitable color sorting item is arranged according still further to the tea seed of different-grain diameter
Part is avoided because tea seed partial size difference is big, and thickness of feed layer is uneven during color sorting, influences the normal detection of color sorting sensor,
The problem of leading to signal acquisition misalignment, reducing precision of color separation, effectively removes the tea seed of mildew, improves the original flavor mountain that squeezing obtains
The quality of tea oil.
3, the clean preparation method of original flavor camellia oil of the invention is easy to operate, and technology stability is good, is suitble to camellia oil
Automation, large-scale production.
