Abstract
The invention relates to a method for removing bitter taste from green tea seed oil. The method comprises the following steps of: 1, squeezing oil, namely squeezing oil by selecting green tea seeds by the traditional method, wherein the squeezing temperature is controlled to be lower than 70 DEG C; 2, washing by using water, namely washing green tea seed crude oil by using clean water or light saline at the temperature of about 40 DEG C; 3, performing alkali refining, namely performing alkali refining on the green tea seed crude oil which is washed by water and a sodium hydroxide solution with 18 to 45 baume degrees to remove acid; 4, adsorbing, namely mixing the green tea seed oil which is subjected to alkali refining and active carbon to adsorb to remove taste and color; 5, removing taste by using water vapor, namely distilling the green tea seed oil by using thermally saturated vapor at high temperuatre and in high-vacuum state to remove taste; and 6, encapsulating, namely pumping the green tea seed oil subjected to the procedures into a packaging workshop for encapsulation. The method has the advantages that: the bitter taste is removed from the green tea seed oil, the finished green tea seed oil can reach the national edible oil standards and the taste-removing process is simple and convenient.
Description
Technical field
The present invention relates to the processing of green tea seed oil, relate in particular to a kind of removal method of green tea seed oil bitter taste.
Background technology
Green tea is the main teas of China, and the whole nation is produced per year more than 100,000 tons, and the scope of China's green tea production has covered the most of areas of China.The green tea seed is the fruit of green tea tree, and the grease that squeezes with the green tea seed is a kind of grease that is rich in high unsaturated fatty acid, but hardship is puckery again, and palatability is poor.Therefore, ripe tealeaves seed is except that the breeding tea tree, and all the other major parts come off naturally, rot in the ground, have caused the waste of resource.There are more than 180 ten thousand mu of tea places in China, and sufficient green tea seed resource is arranged, and output is calculated by 450 kg/ mus; Potential green tea seed resource is about 800,000 t; If can solve the not only bitter but also puckery technical barrier of green tea seed oil, can turn waste into wealth, increase tea grower's income; Promote the agricultural structure adjustment, the sustainable development that keeps green tea to produce.
Summary of the invention
The removal method that the purpose of this invention is to provide a kind of green tea seed oil bitter taste, the green tea seed oil with this method preparation does not have bitter taste, good palatability, and have certain function of health care and nutritive value.
The present invention is achieved in that its method step is:
1, oil expression: the green tea seed of selecting drying and ripening is controlled pressing temperature by the conventional method oil expression: less than 70 ℃, obtain green tea seed crude oil;
2, washing: with about 40 ℃ clear water or light salt brine flushing green tea seed crude oil, washed time 15-30 minute, remove the water-soluble pained material in the green tea seed crude oil;
3, alkali refining: carry out alkali-refining deacidification, alkali refining temperature: 45-60 ℃ with the sodium hydroxide solution of 18-45 Baume degrees and the green tea seed crude oil after the washing;
4, absorption: the tea seed oil behind the alkali refining is mixed with activated carbon, and at vacuum 720mmHg, under the state that temperature is 90 ℃, 1 hour time adsorbed taking off and distinguish the flavor of to decolour;
5, water vapour removes flavor: under high temperature, high vacuum state, green tea seed oil is distilled flavor with overheated saturated vapor, and 160 ℃ of overheated saturated steam temperature, vacuum 750MM mercury column, distillation time are 200 minutes.
6, can: the green tea seed oil pump that will pass through above-mentioned operation is gone into packing shop and is carried out can; Strict control packing shop remains drying, cleaning, bright environment, more than each indoor ultraviolet lamp sterilization 30min, personnel and equipment are by sanitary standard sterilization, the sterilization of regulation.
Advantage of the present invention is: the technology of going to distinguish the flavor of is simple and convenient; And both removed the oily bitter taste of green tea seed, can guarantee that again finished product green tea seed oil reaches national edible oil standard.
The practical implementation method
The present invention is achieved in that its method step is:
1, oil expression: the green tea seed of selecting drying and ripening is by the conventional method oil expression, and the control pressing temperature obtains green tea seed crude oil less than 70 ℃;
2, washing: with about 40 ℃ clear water or light salt brine flushing green tea seed crude oil, washed time 15-30 minute, remove the water-soluble pained material in the green tea seed crude oil;
3, alkali refining: carry out alkali-refining deacidification with the sodium hydroxide solution of 18-45 Baume degrees and the green tea seed crude oil after the washing, the alkali refining temperature is 45-60 ℃;
4, absorption: the tea seed oil behind the alkali refining is mixed with activated carbon, and at vacuum 720mmHg, under the state that temperature is 90 ℃, 1 hour time adsorbed taking off and distinguish the flavor of to decolour;
5, water vapour removes flavor: under high temperature, high vacuum state, green tea seed oil is distilled flavor with overheated saturated vapor, and 160 ℃ of overheated saturated steam temperature, vacuum 750MM mercury column, distillation time are 200 minutes.
6, can: the green tea seed oil pump that will pass through above-mentioned operation is gone into packing shop and is carried out can; Strict control packing shop remains drying, cleaning, bright environment, more than each indoor ultraviolet lamp sterilization 30min, personnel and equipment are by sanitary standard sterilization, the sterilization of regulation.
