Problems solved by technology

For the processing of rapeseed oil, general-purpose refining technology is commonly used in the prior art, which generally has serious over-processing problems, which increases the amount of raw and auxiliary materials used in rapeseed oil refining, increases the consumption and energy consumption of oil refining, and processes waste water. , The discharge of waste residues exceeds the standard, which damages the environment, and also causes the original nutrients in the rapeseed oil to be removed by over-processing, resulting in a decline in the nutritional quality of the rapeseed oil. At the same time, over-processing also makes trans fatty acids in the oil The content of harmful oil accompanying substances increases, which reduces the safety of oil consumption

Abstract

The invention discloses a processing technology for rapeseed oil. As ultrasonic waves can be adopted to assist a phospholipase C degumming process to perform degumming processing on rapeseed crude oil, the water using amount of degumming can be greatly reduced, and the generated wastewater amount can be greatly reduced as well, so that the processing technology is green and environmentally friendly; and the degumming time can be shortened to 60 min, and the processing technology can accord with the moderate refining of oils and fats. The processing technology is safe, environmentally friendly,simple, convenient in operation, low in cost, high in refining rate and suitable for the industrial production of rapeseed oil processing.

Description

technical field [0001] The invention relates to a processing technology of rapeseed oil. Background technique [0002] Rapeseed oil is what we commonly call rapeseed oil, also called coriander oil. It is a transparent or translucent liquid obtained by pressing or leaching the seeds of Brassica cruciferae (that is, rapeseed). It is the most commonly eaten oil in my country. one. Studies have shown that among vegetable oils, rapeseed oil contains the least saturated fatty acid, only 6%, and unsaturated fatty acid accounts for more than 90%. Rapeseed oil is also rich in vitamin E and oleic acid, linoleic acid, linolenic acid and so on. The human body has a high rate of digestion and absorption of rapeseed oil, and the rate of digestion and utilization can reach 99%. Its nutrients can be fully absorbed by the body to promote growth and development, maintain physiological metabolism, reduce cholesterol levels, soften blood vessels, delay aging, and prevent diseases And so on. ...
