Abstract
The invention provides a method for preparing black snake oil. The method comprises the following steps: mashing adipose tissues of black snakes; uniformly filling the mashed adipose tissues in an extraction kettle; pressurizing liquid CO2 to a necessary pressure via a high pressure pump; heating the liquid CO2 to a set temperature via a heating kettle; conveying the liquid CO2 into the extraction kettle from the bottom for extraction; conveying the CO2 dissolved with black snake grease into a separation kettle with lower pressure through a reducing valve to reduce the solubility, so that a solute separates out and deposits on the bottom of the separation kettle, the CO2 is hermetically and circularly used in the entire device; and stopping extracting when a set CO2 circulation volume is up, discharging a product in the separation kettle, and filtering to obtain a black snake oil product. The product prepared by the preparation method provided by the invention is high in oil yield, light in color, high in transparency, free of precipitates and suspended solids, small in viscosity and high in linoleic acid content.
Description
Technical field
The invention belongs to animal oil extraction technical field, be specifically related to a kind of preparation technology of zaocys dhumnades oil.
Background technology
Snake oil contains abundant natural active matter and antipathogenic composition, has superpower seepage force, directly can permeate human body skin, promotes skin cell metabolism, strengthens skin immunization regulatory function; Be a kind of not only being rich in nutrition but also be beneficial to the material of health care, China's traditional Chinese medical science or happiness snake oil disease-treatment and health-care among the people, have endocrine regulation imbalance, relax bowel, skin maintenance, prevents skin aging, prevents arteriosclerosis from having good effect.
Snake oil contains 12 kinds of lipid acid, mainly contains the unsaturated fatty acids such as linolic acid, linolenic acid and glycerine palmitinic acid etc.Wherein maximum unsaturated fatty acidss---linolic acid, the excessive temperature of long period can cause it to be oxidized.
Traditional method is the fat peeling off in health, tempers and form in pot, tempers and unsaturated fatty acids in snake oil can be made easily to be oxidized, and functional component is destroyed, and drug effect is reduced.Disclosed in Chinese patent application " a kind of method of refining snake oil " (CN103468390A), with the fatty tissue of snake for raw material, heating is refined produce liquid, and it is the main liquid of snake oil that filtered while hot obtains filtrate; Remaining filter residue is carried out squeezing to obtain pressed liquor, filters to get filtrate as snake oil contained in filter residue; Snake oil contained in main for snake oil liquid and filter residue is merged, obtains the thick product of snake oil; Thick for snake oil product is dissolved in organic solvent repeatedly extract, extracts under ultrasonic wave, adopt the method recycling design of distillation, and logical nitrogen, obtain this refining snake oil.Although the method has done certain improvement in traditional method; shorten and boil the time; quality product is had a certain upgrade, but still does not depart from high temperature and boil this link, the snake oil preparation method tool therefore developing a kind of available protecting snake oil functional component is of great significance.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, order of the present invention is just to provide the preparation method that a kind of extraction efficiency is high, improve the zaocys dhumnades oil of functional component in snake oil
.
For achieving the above object, the present invention adopts following technical scheme: a kind of zaocys dhumnades oil preparation method, with the fatty tissue of zaocys dhumnades for raw material, suitably smash to pieces, uniform filling in extraction kettle, liquid CO
2be forced into required pressure through high-pressure pump, be heated to the temperature set by heating kettle, entered in extraction kettle by bottom and extract, be dissolved with the CO of zaocys dhumnades grease
2enter the lower separating still of pressure through reducing valve and cause solubleness to reduce, solute is separated out, and is deposited on the bottom of separating still, CO
2in whole device, sealing and circulating utilizes, when reaching the CO of setting
2stop extraction during internal circulating load, release the product in separating still, filter and be zaocys dhumnades oil production.
The preparation method of described zaocys dhumnades oil, comprises the following steps:
(1) by smash to pieces snake fat uniform filling to supercritical CO
2in the extraction kettle of abstraction instrument, and close extractor;
(2) gas cylinder is opened, liquid CO
2after cooling, be forced into 20-30MPa through high-pressure pump, then be heated to 45-50 DEG C by heating kettle, entered in extraction kettle by bottom and extract, be dissolved with the CO of zaocys dhumnades grease
2entering through reducing valve the separating still that setting pressure is 6-8MPa, temperature is 45-50 DEG C causes solubleness to reduce, and solute is separated out, and is deposited on the bottom of separating still, CO
2in whole device, sealing and circulating uses;
(3) CO is worked as after 5-6 hour
2internal circulating load stops extraction when reaching 10-12kg, and open separating still baiting valve, obtain product, 300 orders filter and obtain zaocys dhumnades oil production.
As optimization, in step (1), the fatty tissue of described snake is the fat that zaocys dhumnades belly obtains.
As optimization, in step (2), described extracting pressure is 20MPa, and extraction temperature is 50 DEG C; Parsing pressure is 8MPa, and resolution temperature is 40 DEG C
As optimization, in step (3), described CO
2internal circulating load is 10kg.
Advantage of the present invention is: what present method adopted is the zaocys dhumnades fat be relatively easy to get is raw material, does not adopt traditional method of tempering completely, but adopts supercritical CO
2extraction process extraction snake oil, mild condition, temperature is low to moderate 50 DEG C and following, effectively avoids that Yin Wendu in traditional snake oil refining method is too high and functional component that is that cause destroys a difficult problem.It is about 10% that tradition tempers method gained snake oil linoleic acid content, supercritical CO of the present invention
2extraction process linolic acid is about 19%.The product oil yield that the present invention obtains is high, lighter color, and transparency is high, and without precipitation and suspended substance, stickiness is less, and linoleic acid content is high.
