Abstract

The invention discloses a method for extracting rapeseed oil by using microwaves. The method comprises the following steps that (1) rapeseed raw materials are cleaned, dried and crushed so as to obtain rapeseed meal; (2) the rapeseed meal and a cellulase aqueous solution are uniformly mixed, and microwave treatment is carried out so as to obtain a mixed material; (3) the mixed material is filtered, washed with water and dried so as to obtain dried rapeseed meal; and (4) the dried rapeseed meal is soaked with a leaching agent and is filtered, and the leaching agent is removed so as to obtain afinished product of the rapeseed oil. The method for extracting the rapeseed oil has the advantages that the process is simple, the production conditions are mild, the loss of nutritional ingredientsis small, the oil yield is high, the product quality is good, refining is not needed, and the production is convenient, rapid and efficient.

Description

technical field [0001] The invention belongs to the technical field of edible oil processing, and in particular relates to a method for extracting rapeseed oil. Background technique [0002] Rapeseed oil, commonly known as rapeseed oil and coriander oil, is a transparent or translucent liquid made from the seeds of Brassica cruciferae, that is, rapeseed. Rapeseed oil is rich in nutrients and can be well absorbed by the body. It not only contains unsaturated fatty acids such as oleic acid, linoleic acid, and linolenic acid, but also contains essential nutrients such as vitamin E, protein, and phospholipids. The effect of aging is very beneficial to human health. The average content of oleic acid in rapeseed oil is about 61%, second only to olive oil, and it is a healthy and high-quality vegetable oil variety. Existing methods for preparing rapeseed oil are mainly pressing method and leaching method. The oil yield rate of the pressing method is low, and the quality of the fi...
