Problems solved by technology

[0003] At present, edible oil is mostly produced by pressing method or atmospheric pressure solvent extraction method. The yield of refined oil is low, the solvent residue is high, and the nutritional components in the oil are seriously damaged under high temperature conditions. Not only the nutritional value of edible oil products is low, but also the safety is guaranteed. Poor, no competitive advantage, and there is still a lot of waste of raw materials and resources
There are very few powerful companies that have adopted CO2 supercritical extraction technology, which can extract better quality oil products, but the one-time investment in equipment is large, and because the extraction is carried out under high pressure, the extraction volume is small (maximum 1000 liters), the production capacity is limited, it is impossible to form industrialized large-scale production, the product cost is high, and the product has no market competitive advantage

Abstract

The invention provides a method for extracting wheat germ compound oil, comprising 7 steps of raw material crushing-microwave treatment-compound enzymatic oil extraction-demulsification-oil cleaning-decolorization-deodorization; The blasting of germ and sesame can fully inactivate various enzymes in wheat germ and sesame, and avoids the damage of high-temperature inactivation of enzymes to nutrients, creating conditions for the subsequent extraction process; the microwave treatment process in the present invention can make Part of the cell wall of the crushed wheat germ and sesame is broken and expanded, so that part of the fat is in a free state, which can effectively improve the extraction efficiency of the compound oil; in addition, the present invention combines the process of enzyme extraction-de-emulsification to effectively reduce the loss of oil , improved the extraction rate of oil; moreover, the present invention adopts the technology of salt washing-water washing, can wash away the impurity in the oil, makes the obtained oil product high in purity, good in color and luster, excellent in quality.

Description

technical field [0001] The invention belongs to the technical field of edible oil refining methods, and in particular relates to a method for extracting wheat germ compound oil. Background technique [0002] Wheat germ oil is a kind of grain oil made from wheat germ. It is rich in various nutrients in wheat and has always been favored by people. Wheat germ oil is rich in unsaturated fatty acids, natural vitamin E, sterols, octacosyl alcohols, cephalin, lecithin and many other beneficial ingredients. It is a nutritional and health-care substance with high nutritional value. The nutritional components and proportions in wheat germ oil are very in line with human health standards. A large amount of unsaturated fatty acids in it can protect the human blood circulation system, treat cardiovascular and cerebrovascular diseases, prevent arteriosclerosis, and lower blood sugar and blood pressure. and cholesterol content have good effect; wheat germ oil has been widely used in food,...
