Abstract

The invention discloses a processing process for rapeseed oil. The process comprises the following steps of (1) carefully selecting rapeseeds of the year, drying the rapeseeds in the sun until the water content is 9 to 11 percent, and removing impurities, wherein the oil content of the rapeseeds is 36 to 39 percent; (2) crushing the rapeseeds, and performing flasking to obtain rapeseed flakes; (3) steam-roasting the rapeseed flasks for 70 to 80 minutes by utilizing the natural water of the flasks; (4) placing the steam-roasted rapeseeds in an oil press, and pressing the rapeseeds to extract crude oil at low temperature of 60 to 70 DEG C; (5) filtering the crude oil by using a conventional method, and performing refining to obtain a rapeseed oil finished product. According to the process, the rapeseeds with the oil content of 36 to 39 percent are taken as raw materials, and are subjected to the steps of drying in the sun, steam-roasting, low-temperature pressing and the like, the obtained rapeseed oil is a non-transgenic product, the intrinsic flavor, aroma and nutrient substances of the rapeseed oil are maximally maintained, the oil yield is over 35 percent, the requirements of green processing are met, and the food safety is ensured.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a processing technology of rapeseed oil. Background technique [0002] Rapeseed oil, commonly known as rapeseed oil, also known as coriander seed oil, is a transparent or translucent liquid obtained by pressing the seed rapeseed of the cruciferous plant Brassica (ie rapeseed). Generally dark yellow or brown. Rapeseed oil contains 0.4-1.0% arachidic acid, 14-19% oleic acid, 12-24% linoleic acid, 31-55% erucic acid, and 1-10% linolenic acid. From the perspective of nutritional value, the human body can digest and absorb rapeseed oil as high as 99%, and it has a gallbladder function. Therefore, rapeseed oil is the main dietary oil for consumers in our country. Its quality is related to the health of Chinese people and also reflects the processing level of my country's oil industry. Rapeseed is an important oil crop among the four major oil crops in the world, and it is al...
