AI Technical Summary

Problems solved by technology

Requires further technical treatment of demulsification, which causes waste of energy and time
At the same time, due to the high content of water in the traditional water enzymatic method, the phenolic substances have strong polarity and are easily soluble in water, resulting in the loss of trace nutrients.

Abstract

The invention discloses a production process of low-erucic acid rapeseed oil, wherein the production process comprises the following steps: (1) cleaning rapeseeds cleanly, and removing chippings, shriveled seeds and impurities; (2) carrying out moisture regulation on the rapeseeds subjected to impurity removal to enable the moisture content to be 0.5-1 wt%; (3) crushing, sieving and pressing the rapeseeds obtained in the step (2) to obtain primary crude oil; (4) taking water accounting for 0.05-0.1% of the weight of the primary crude oil and compound enzyme accounting for 0.09-0.3% of the weight of the primary crude oil, mixing, uniformly stirring, adding into the primary crude oil, and carrying out enzymolysis; (5) after the enzymolysis is finished, adding petroleum ether for extraction, and separating out a water layer to obtain an oil layer; and (6) after petroleum ether in the oil layer is completely recovered, obtaining rapeseed oil. The rapeseed oil prepared by the method retains more micronutrient active ingredients, and is high in tocopherol, sterol and beta-carotene content and low in erucic acid content.

Description

technical field [0001] The invention belongs to the technical field of rapeseed oil, and in particular relates to a low erucic acid rapeseed oil and a production process thereof. Background technique [0002] Rapeseed is one of the world's important grain and oil crops, accounting for about 25% of the world's total grain and oil production. Since the 1950s, with the development of the oil industry in the world, the production and output of rapeseed have increased significantly. Rapeseed oil is a kind of nutrient-rich oil. The content of unsaturated fatty acids accounts for more than 80%, of which oleic acid is more than 40%. It is easily absorbed by the human body and has good frying and anti-oxidation properties. The content of serum cholesterol in the body can prevent and treat arteriosclerosis, promote microvascular circulation, prevent colon cancer, reduce blood pressure and lose weight, especially beneficial to obesity, high blood pressure, heart disease, arteriosclero...
