Problems solved by technology

Its production efficiency is low and the product cost is high
In addition, after carbon dioxide supercritical extraction, there is still a small amount of oil that has not been extracted. The existence of these oils directly affects the extraction rate of amygdalin

Embodiment 1

[0024]Example 1 Get 100 kilograms of bitter almond meal with a particle size less than 3 mm, and check that the proportion of oil is 5%, and the proportion of amygdalin is 6.7%. Put the above-mentioned bitter almond meal into the extraction kettle of the supercritical carbon dioxide extraction equipment, adjust the pressure in the kettle to 26Mpa, and the temperature to 82°C, start the operation of the equipment, add carbon dioxide liquid and food-grade absolute ethanol into the extraction kettle, and the liquid carbon dioxide Add-on is 1000 kilograms, and dehydrated alcohol add-on is 1206 kilograms. The two are introduced into the extraction kettle and extracted for about 15 minutes. Carbon dioxide and its extract bitter almond oil, absolute ethanol and its extract amygdalin are introduced into the primary separator. The temperature and pressure in the primary separator are respectively 45°C and 17Mpa, in the primary separator, the fat is separated from carbon dioxide, absolu...

Abstract

The invention relates to an extraction method for laetrile. Hypercritical carbon dioxide is adopted to be added with an absolute ethyl alcohol entraining agent; in hypercritical carbon dioxide equipment, extraction is carried out to bitter almond meal after degreasing in an extraction kettle; then primary separation, secondary separation and low-temperature crystallization are carried out, and a crude product of the laetrile is obtained. After the crude product of the laetrile is dissolved by using absolute ethyl alcohol secondarily, the temperature is reduced to -3 DEG C-4 DEG C, thus obtaining a fine product of the laetrile. The extraction method for the laetrile has simple and convenient extraction procedure, short extraction time, target products with high yield and low overall cost; the products do not have harmful residual solvents.

Description

technical field [0001] The invention relates to a method for extracting active substances from plants, in particular to a method for extracting and refining amygdalin from plants. Background technique [0002] In the prior art, the methods for extracting amygdalin from wild plants are generally as follows: one is to degrease (skim) the almonds by pressing, and then add solvents such as ethanol and ether to the defatted almond meal to extract amygdalin under low pressure. Glycosides, such as the "Extraction, Separation and Refining Method of Active Ingredient Amygdalin" disclosed in Chinese Patent No. 02100460.9; and "Research on Ethanol Extraction Technology of Amygdalin" disclosed in "Food Industry Science and Technology" 2005, 26 (3) 118-119, etc. , this process squeezes bitter almonds to remove oil, adds 3-6 times the amount of ethanol to extract 3 times, filters under reduced pressure, combines the filtrates, recovers ethanol to an appropriate amount under reduced pressu...
