Problems solved by technology

[0003] The traditional rapeseed oil production process is divided into two types: mechanical pressing and solvent leaching. The mechanical pressing process uses physical extrusion to squeeze oil out of rapeseed. It is divided into hot pressing and cold pressing. General hot pressing will seriously damage rapeseed cells, and will destroy the nutrients in the oil after high temperature, reducing the nutritional value and quality of rapeseed oil, while the oxidation stability of cold-pressed oil is not very ideal, and the oil yield is low

Abstract

The invention discloses a processing method for high-quality rapeseed oil. The processing method comprises the following steps: dehulling rapeseeds, and then carrying out microwave treatment on the dehulled rapeseeds to obtain rapeseed kernels; adding lotus oligomeric proantho cyanidins oligomer in ethyl acetate, stirring uniformly and then adding sodium bicarbonate and stearyl chloride, feeding nitrogen and carrying out oscillatory reaction, filtering, washing, carrying out rotary evaporation, drying and grinding to obtain modified lotus oligomeric proantho cyanidins oligomer; ultrasonicallyextracting honeysuckles, pomegranate barks, eucommia ulmoides, star anise, pyracantha fortuneana fruits, fructus forsythiae and lygodium japonicum, filtering, adding the modified lotus oligomeric proantho cyanidins oligomer, and stirring uniformly to obtain a soak solution; heating the soak solution, adding the rapeseed kernels, soaking the rapeseed kernels in the soak solution, filtering and thendrying, parching, and adding water to carry out tempering so as to obtain the tempered rapeseed kernels; squeezing the tempered rapeseed kernels in a screw press to obtain crude oil, and precipitating, filtering, decoloring and centrifuging the crude oil to obtain rapeseed oil; and mixing the rapeseed oil with soybean oil and peanut oil.

Description

Technical field [0001] The invention relates to the technical field of rapeseed oil, in particular to a processing method of high-quality rapeseed oil. Background technique [0002] Rapeseed is one of the main oil crops in my country, with an annual output of 13 million tons. The rapeseed oil produced from it has high nutritional value and is easily absorbed by the human body. Its main component is triacylglycerol, and it also contains rapeseed polyphenols and tocopherols. , Plant rapeseed sterols and rapeseed polyphenols and other micronutrients, these nutrients have a variety of physiological activities and health functions, making rapeseed oil one of the traditional edible vegetable oils in my country. [0003] The traditional rapeseed oil production process is divided into two types: mechanical pressing and solvent extraction. The mechanical pressing process uses physical extrusion to squeeze the oil from the rapeseed. It is divided into two types: hot pressing and cold pressing...
