Abstract

Belonging to the technical field of fine processing of quinoa bran, the invention discloses an extraction method of grease in quinoa bran and application of the grease in food. The method has simple extraction process and high extraction efficiency, the extracted quinoa bran grease can be applied to the food field to prepare plant blend oil, thus increasing the utilization value of quinoa bran andenhancing the economic benefits. The obtained blend oil is rich in arachidonic acid and unsaturated fatty acid, wherein arachidonic acid is an important substance for the development of human brain and optic nerves, plays an important role in improving intelligence and enhancing visual acuity, has a series of physiological activities like esterifying cholesterol, increasing vascular elasticity, reducing blood viscosity, regulating blood cell function, etc., and has important efficacy on prevention of cardiovascular diseases, diabetes, tumors and the like.

Description

technical field [0001] The invention relates to the technical field of quinoa bran finishing, in particular to a method for extracting oil from quinoa bran and its application in food. Background technique [0002] Quinoa, a dicotyledon pseudocereal of the genus Amaranthaceae, is usually discarded, causing a lot of waste, because the bran is too bitter in the process of traditional quinoa processing and eating, so it is not suitable for feeding and eating. It also pollutes the natural environment. Quinoa bran is rich in nutrients, such as protein, dietary fiber and oil. Quinoa oil is rich in unsaturated fatty acids, which have health effects on diseases such as hypertension, hyperglycemia and hyperlipidemia. [0003] It is known that the oil extraction rate of quinoa in the supercritical extraction method is 4.13%, while the oil content in quinoa bran can reach 14.15%, which is much higher than the extraction rate of quinoa. Among them, in the oil extracted from quinoa bra...
