Abstract

The invention discloses a co-production method for extracting idesia polycarpa oil and idesia polycarpa whitening essence with multi-enzymatic and wet processes. The co-production method includes pretreatment, boiling, enzymolysis, centrifugation, oil extraction and idesia polycarpa whitening essence extraction. The co-production method is a wet-process oil extraction technique, idesia polycarpa fruit are taken as raw materials, the idesia polycarpa whitening essence is extracted from pomace while the idesia polycarpa oil is extracted to turn waste into treasure, high added value of production and economic benefit are brought to planting farmers and enterprises, and the method has great practical significance and strategic significance; with the method, co-production and comprehensive utilization of oil and active ingredients are realized, the traditional oil refining process is simplified, and energy consumption is lowered; the idesia polycarpa oil prepared with the method is free of bitterness, and the problem that bitterness of the idesia polycarpa oil is hard to remove is solved; the method is simple to operate, convenient for preparation, low in cost and suitable for industrial large-scale production.

Description

technical field [0001] The invention relates to a method for extracting oil and whitening essence, in particular to a co-production method for extracting Jatropha jatropha oil and Jatropha jatropha oil and whitening essence by a multi-enzyme wet method. Background technique [0002] Tung tree is a native tree species in my country. Its fruit, pericarp and seeds all contain oil, among which the oil content of pulp is 40%-45%, and the oil content of zongzi is 22%-25%. The linoleic acid in the tung seed oil is as high as 51%-81%. It has a good ratio of fat and acid. It is a high-quality health-care woody edible oil. In particular, Jatropha jatropha oil contains DHA, which is rarely found in other vegetable oils. Since linoleic acid is related to the synthesis of prostaglandins and squalene in the human body, and DHA is an important substance that constitutes the plasma membrane of the brain, Jatropha jatropha Oil has high nutritional value and health care. The iodine value of...
