Abstract
The invention discloses a process for extracting black tea oil. The process comprises the following steps: (1) selecting, washing, drying and crushing 60-100 kg of choice black tea seeds; (2) uniformly mixing the crushed black tea seeds in a centrifugal pipe after water is added inside; (3) performing enzyme killing of the uniformly-mixed black tea seeds in a water bath; (4) cooling to the room temperature, adjusting the pH value, performing enzymolysis in a frozen constant-temperature oscillator under the conditions of set enzymolysis temperature and set enzymolysis time; (5) performing enzyme killing after the reaction is finished; and (6) centrifuging for 35-40 minutes in a centrifugal machine. The process for extracting the black tea oil disclosed by the invention has lower requirements for equipment and mild action conditions, and oil extracted according to the process disclosed by the invention has higher quality; the process for extracting the black tea oil disclosed by the invention can effectively recover tea saponin, protein and carbohydrates in plant raw materials while extracting the oil, and truly meets the requirements of safe, high-efficiency and green production of edible oil.
Description
Technical field
The present invention relates to a kind of extraction process of oil, particularly relate to a kind of extraction process of black tea oil.
Background technology
The extraction process kind of tea oil is more various, and modal have milling process, organic solvent extractionprocess, solvent extraction method, microwave treatment method etc., but milling process exists oil yield is low, labour intensity is large, production efficiency is low, cake slag resid amount is high shortcoming; The shortcoming of organic solvent extractionprocess and solvent extraction method is that in Extractive crudeoil, oleaginous materials is more, and color and luster is dark, second-rate, and containing a certain amount of residual solvent; Microwave treatment method is on the certain influence impact again of the quality parameter such as POV value, acid value, color of tea oil.Therefore, need to find that a kind of extraction process is simple, oil yield is high, the extraction process of fuel-displaced quality better.
Summary of the invention
The present invention is exactly for the problems referred to above, proposes a kind of extraction process of the black tea oil based on aqueous enzymatic method, and the tea oil oil yield that this technique is extracted is high, tea oil quality better, can preserve the nutritive substance in tea oil in good condition, and technique is simple.
For reaching above-mentioned technical purpose, present invention employs a kind of extraction process of black tea oil, being made up of following steps:
(1) choose without mildew, evengranular black tea seed 60-100kg, and clean, dry, pulverize;
(2) the black tea seed after pulverizing is put into 600 milliliters of centrifuge tubes, add water 260-280 milliliter, and mix;
(3) the black tea seed of mixing being carried out under the temperature condition of 90-95 DEG C 12-15 divides water-bath to go out enzyme;
(4) be down to after room temperature enzyme-added after adjust ph, be positioned in freezing thermostat vibrator, under the hydrolysis temperature and enzymolysis time of setting, carry out enzymolysis;
(5) under 90-95 DEG C of temperature condition, carry out water-bath 10-15 minute after having reacted to go out enzyme;
(6) with the centrifugal 35-40 minute of 8000-9000r/min.
In described step (4), pH value is 7.6-7.9.
In described step (4), the hydrolysis temperature of setting is 60-65 DEG C, and described enzymolysis time is 30-35 minute.
The extraction process of black tea oil of the present invention is not high to equipment requirements, action condition is gentleer, oil plant is without high thermal treatment, do not relate to organic solvent, institute's oil quality of carrying is higher, while carrying oil, and the tea soap in energy efficient recovery plant material, protein and carbohydrate, really meet the requirement that edible fat production is safe, efficient, green.
Embodiment
Embodiment is adopted to be described in more detail the present invention below.
An extraction process for black tea oil, is made up of following steps:
(1) choose without mildew, evengranular black tea seed 60-100kg, and clean, dry, pulverize, preferably use special cleaning machine to clean, to improve cleaning performance during cleaning; Dry and pulverizing also preferably adopts special siccative and pulverizer;
(2) the black tea seed after pulverizing is put into 600 milliliters of centrifuge tubes, add water 260-280 milliliter, and mix;
(3) the black tea seed of mixing being carried out under the temperature condition of 90-95 DEG C 12-15 divides water-bath to go out enzyme;
(4) be down to after room temperature enzyme-added after adjust ph, be positioned in freezing thermostat vibrator, under the hydrolysis temperature and enzymolysis time of setting, carry out enzymolysis;
(5) under 90-95 DEG C of temperature condition, carry out water-bath 10-15 minute after having reacted to go out enzyme;
(6) with the centrifugal 35-40 minute of 8000-9000r/min.
In step of the present invention (4), pH value is 7.6-7.9.
In step of the present invention (4), the hydrolysis temperature of setting is 60-65 DEG C, and described enzymolysis time is 30-35 minute.
In the present invention, the account form of final oil extracting rate is: the quality * 100% of oil in (quality oily in quality-residue oily in raw material)/raw material, draws final oil extracting rate.
Reach a conclusion through test of many times: the oil yield of the black tea oil adopting extraction process of the present invention to extract is at 92-93%.
