Abstract

The invention discloses a method of treating water and sediments in crude rapeseed oil by utilizing a cold filtering process technology and relates to a method of carrying out freezing crystallization by adding water to the squeezed crude rapeseed oil and removing the water and the sediments by segmented multistage filtering. The method comprises the following steps: (1) selecting rapeseeds, and removing the water and the sediments; (2) carrying out flaking by virtue of a flaking mill; (3) carrying out frying by virtue of a roller seed frying machine; (4) squeezing to obtain thick aroma crude rapeseed oil; (5) removing large impurities by virtue of an oil clarification tank; (6) carrying out primary filtration; (7) carrying out freezing crystallization by adding water; (8) filtering in a blade; (9) fine filtration by virtue of pressure; and (10) filling. By adopting the method, any chemical component such as acid, base and the like is not added, the nutritional ingredients of the rapeseed oil needed by a human body such as inherent fragrance, vitamins, phytosterol and the like are also reserved to the maximum, the method accords with the green processing requirement, and food safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a method for treating oil and water impurities of Luzhou-flavored rapeseed by cold refining technology. 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 (rapeseed rape), 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, and its quality is related to the health of Chinese people. , It also reflects the processing level of my country's oil industry. Rapeseed is an importa...
