Abstract
A kind of camellia seed oil low-temperature cold pressing preparation technology, comprises the following steps: the pre-treatment of (1) tea seed; (2) the strong tea seed stored carry out clearing up, shell shell, pulverize, add water modified, squeezing; (3) adopt the filter of two kinds of different sizes to carry out multi-filtering to above-mentioned coarse tea oil and obtain tea oil; (4) filter at low temperature; (5) decolorization adsorption.This processing method is simple and easy to do, and expressing process does not lose the fragrance of sincere nutritive ingredient, active substance and tea oil itself, and refining process does not produce secondary pollution, and the pressed tea seed oil obtained presents the limpid exterior beauty of oil colours.
Description
Technical field
The present invention relates to the processing technique field of camellia seed oil, specifically a kind of camellia seed oil low-temperature cold pressing preparation technology.
Background technology
Camellia oil refines in Wild Woody oil section fruit, is one of large xylophyta oil in the world four.In fact the dietotherapy dual-use function of China's tea oil is better than sweet oil, except the lipid acid composition of two kinds of greases and oil property, nutritive ingredient similar except, tea oil is also containing the unexistent specific physiologically active substance tea-polyphenol of sweet oil and camellianin (i.e. TS, or title tea saponin).
The noble quality of tea oil Normal juice, the requirement of meet again people's uphold nature, improving the quality of living is the fine work in current edible oil.
Tea oil has satisfactory stability, long quality-guarantee period, and smoke point height is high temperature resistant, and good antioxidant property is easy to digest and assimilate.The method of existing tea seed oil expression, QI-insufficiency part is that tea seed will enter to steam and fries operation, and steams the fragrance that the high temperature fried is easy to lost sincere nutritive ingredient, active substance and tea oil itself.The coarse tea oil that traditional refinery practice also will come squeezing out carries out vacuum-drying, vacuum decoloration, high temperature high vacuum deodorization processing, and the effective constituents such as the sterol in tea-seed oil can be caused to cause a large amount of loss simultaneously.
Summary of the invention
The present invention aims to provide a kind of camellia seed oil low-temperature cold pressing preparation technology, overcome the deficiencies in the prior art, improve the quality of the tea seed of raw material, ensure that the quality of raw tea material seed, through multi-filtering, filter at low temperature refinery practice, avoid the secondary pollution that the chemical substance in common process directly contacts with tea oil
The invention provides following technical scheme:
A kind of camellia seed oil low-temperature cold pressing preparation technology, comprises the following steps:
(1) pre-treatment of tea seed: dried by the oil tea fresh fruit of collection, carries out the separation of stripping Pu and obtains fresh tea seed, store after 0-5 DEG C of cryodrying;
(2) the strong tea seed stored carry out clearing up, shell shell, pulverize, add water modified, squeezing;
(3) adopt the filter of two kinds of different sizes to carry out multi-filtering to above-mentioned coarse tea oil and obtain tea oil;
(4) filter at low temperature: tea oil is carried out multi-filtering and low temperature crystallization in the low temperature environment of about 9-10 DEG C;
(5) decolorization adsorption: be first 96kpa by filtration tea oil in vacuum tightness, temperature is under the condition of 70-100 DEG C, dehydration is stirred with the stirrer that setting rotating speed is 60r/min, then add the filler atlapulgite had no side effect by weight of oil 2%, then stirrer adjustment of rotational speed is greater than 60r/min rapid stirring, decolouring 0.5h, tea oil after decolouring is 100kpa in vacuum tightness, temperature is carry out distillation 5h under 110 DEG C of conditions, is then cooled to less than 70 DEG C vacuum breakers, obtains finished product tea oil after filtration.
The described cryodrying part of step (1) is carried out for twice, and drying temperature is 50-55 DEG C for the first time, and time of drying is 50-60min, and second time drying temperature is 60-65 DEG C, and time of drying is 40-45min.
Fresh tea seed after peeling off described in step (1) at 3 hours inner dryings to moisture 8%.
Add water described in step (2) modified in the temperature of moisture be 60 DEG C.
Add water described in step (2) modified in water volume be 2-3%.
Add water described in step (2) modified step: the tea seed powder after pulverizing is added modified pot, modified pot is upright three-decker, every layer height is consistent, every layer of feed opening is in the same size and be in staggered distribution, add water at upper first layer, add water and be stirred to the second layer, after second, third layer continues to stir, enter the materials-stored box of squeezing.
Compared with prior art, beneficial effect of the present invention is as follows:
(1) improve the quality of the tea seed of raw material, ensure that the quality of raw tea material seed;
(2) the inferior tea seed raw material unavoidably gone mouldy enters in production technique, ensure that squeezing quality of crude oil;
(3) high temperature is avoided and the tea oil color and luster that causes is dark, burning and tea saponin sex change;
(4) through multi-filtering, filter at low temperature refinery practice, the secondary pollution that the chemical substance in common process directly contacts with tea oil is avoided.
