Problems solved by technology

There are potential safety problems in organic reagents, and crude oil must be refined, and the organic reagents used are easy to volatilize and pollute the environment. In addition, the disposal of organic reagents is also troublesome, requiring special workshops and equipment
The natural nutrients in the refined camellia oil are almost completely lost, high-temperature deodorization produces trans fatty acids or benzopyrene, which are harmful to health, and organic solvents are left in organic extraction, which greatly reduces the quality of camellia oil

Abstract

A method for extracting tea-seed oil by microwave expansion assisted biological enzymolysis includes steps of cleaning and removing impurities, unshelling, smashing, preprocessing by a microwave expander, subjecting to enzymolysis, physically cold pressing, dehydrating and removing impurity to obtain tea-seed oil, wherein the enzymes fluid system comprises pectinase, cellulose, protease and alpha-amylase according to the volumetric ratio (1-2): (2-3): (1-2): (2-3). By the aid of the microwave expansion assisted biological enzymolysis, the method is a novel organic tea oil extracting method combined with an ultrasonic wave processing extraction technology. Microwave assistance has efficiency and selectivity in promoting reaction and has the advantages of convenience in operation, few side products, high yield and easy purification of products and the like.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a method for extracting tea seed oil through microwave puffing-assisted biological enzymatic hydrolysis. Background technique [0002] Camellia oil is a high-grade healthy edible vegetable oil, the main component is oleic acid, and contains linoleic acid, palmitic acid, stearic acid, etc. The relative content of oleic acid in camellia oil accounts for 76-85%, which is almost oleic acid in all common vegetable oils. highest content. It also contains 7-8% linoleic acid and 9-10% saturated acid. Due to its high degree of unsaturation, it is very beneficial for patients with heart disease, arteriosclerosis, hypertension, and hyperlipidemia. It is an ideal nutritional and health-care oil. Tea oil is cool in nature and has the effect of cooling blood and stopping bleeding. Long-term consumption can have a special effect on suppressing blood pressure in hypertensive patients c...
