Problems solved by technology

The research report on this technology in our country is relatively late. Since Wang Zhang and Professor Xu Shiying reported the extraction of soybean oil by aqueous enzymatic method for the first time in China in 1994, the application of this technology is limited to soybean, corn germ, rapeseed and peanut and other oil crops.

Abstract

The invention discloses a method for extracting a fragrant sunflower seed oil and belongs to the extraction processing technique of plant fat. The method comprises the following steps: (1) frying cleaned sunflower seeds; (2) carrying out extrusion puffing pre-treatment to the fried sunflower seeds to obtain pressed fragrant sunflower oil and a puffed product; (3) mixing the puffed product obtained in the step (2) with water to obtain mixed solution, adding compound cellulose to the mixed solution to enzymatically hydrolyze and obtain an enzymatic hydrolysate; (4) enzyme-inactivating the enzymatic hydrolysate and centrifugally separating to obtain the free fragrant sunflower seed oil. According to the method of extracting the fragrant sunflower seed oil, the sunflower seed oil is separated in a method of combining frying, extrusion puffing pretreatment and bio-enzyme; after the emulsified oil subjected to separation is demulsified, the oil of high quality can be obtained without refining and has high nutritional value; the total oil extraction rate is up to 96.98 percent; the action conditions are mild and degradation products in the system are not reacted with the extract, so that the qualities of various components can be protected effectively.

Description

technical field [0001] The invention belongs to the extraction and processing technology of vegetable oil, and in particular relates to an extraction method of strong fragrance sunflower oil. Background technique [0002] At present, the mechanized oil processing technology used in sunflower seed oil production has gradually developed from the cumbersome manual workshops and semi-mechanized production of oil processing in the 1950s and 1960s. The technological process of sunflower seed oil production is: shelling, pre-pressing, and leaching. The sunflower seed extraction process and equipment are the same as soybean and rapeseed processing. [0003] The pressing method is also called the physical oil production method, which produces vegetable oil through raw material grinding, pressing, refining and other processes. The leaching method is also called the chemical oil production method, which produces vegetable oil through raw material crushing, solvent soaking, precipitat...
