Abstract

The invention discloses a method for preparing oil by a low aqueous enzymatic method and organic solvent extraction. The method comprises the following steps of: based on 100 Kg of oil plants, dissolving 0.5 to 3.0 Kg of complex enzyme which comprises cellulolytic enzyme, pectinase, protease, and flavourzyme in a ratio of 2 to 3 to 4 to 3 in 40 to 70L of buffer solution with the pH value of 5.0 to 7.0 to obtain enzyme solution; cleaning the oil plants and removing impurities, crushing and sieving, wherein the particle diameter is 40 to 80 meshes; spraying the enzyme solution onto the crushed oil plants, stirring uniformly, and reacting at the constant temperature of between 40 and 55 DEG C for 2 to 4 hours; placing the reacted materials in a drying oven at the temperature of between 40 and 65 DEG C and drying for 2 days; hardening and tempering the materials to ensure that the moisture content is kept to be 3+ / -5 percent; and extracting the dried, hardened and tempered materials by anorganic solvent at the temperature of between 50 and 70 DEG C for 1 to 2 hours to obtain the extraction oil and egg oil material cakes. The method is high in oil yield, and the obtained oil and cake have high quality.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to an enzyme-assisted oil production method. Background technique [0002] At present, the methods of extracting oil mainly include organic solvent extraction and aqueous enzymatic pretreatment oil extraction. The main method of the organic solvent extraction method is: after the oil is cleaned, crushed, and sieved, it is added to petroleum ether or No. 6 solvent, extracted for a period of time with an extractor, ultrasonic wave, etc., and then refined through deacidification, deodorization, etc. to obtain edible oil. This method is convenient to use and easy to operate, but it also has disadvantages such as relatively long oil extraction time, low oil extraction efficiency, and large solvent consumption. Aqueous enzymatic pretreatment oil extraction method is an enzyme preparation that can degrade vegetable oilseed cell walls, lipid bodies and their complexes (lipoprotein,...
