Embodiment Construction

[0015] A process for producing rapeseed oil includes the following steps:

[0016] (1) Clean the rapeseed and dry it to a moisture content of 5-8%;

[0017] (2). After the dried rapeseed is fried and fragrant, crush it;

[0018] (3) Send the crushed rapeseed to the oil press to squeeze the oil to obtain virgin rapeseed oil;

[0019] (4) Take out the pressed rapeseed cake, put it in a steamer, steam it in steam at 120-130℃ for 15 minutes; then grind the rapeseed with 7% white vinegar as a medium, stand still, and filter to obtain a vinegar mill Rapeseed oil

[0020] (5) After the virgin rapeseed oil and vinegar-milled rapeseed oil are combined, add 60% of the oil weight of deionized water and 3.5% sodium bicarbonate, heat to 60-70°C, stir for 40 minutes, and let stand Precipitate for 5-6 hours, filter to remove impurities; then, add citric acid equivalent to 2% of the oil weight, dissolve in the water phase, heat to 40-50℃, stir for 30-40 minutes, stand still, filter to remove the prec...

Abstract

The invention discloses a production technology of rapeseed oil. The production technology comprises the following steps of: (1) washing rapeseeds cleanly, and drying until the moisture content is 5-8%; (2) frying the dried rapeseeds to have fragrance, and then grinding; (3) feeding the ground rapeseeds into an oil press for pressing oil to obtain primarily pressed rapeseed oil. The harmful substances in the rapeseeds can be effectively damaged by grinding rapeseed cakes with white vinegar after the fried rapeseed cake is primarily pressed, the oil yield of the rapeseeds can be greatly increased, and the decoloration and heavy metal ion removal effects can be improved by adopting a modified decolorizing agent.

Description

Technical field [0001] The invention mainly relates to a rapeseed oil and a preparation method thereof, and belongs to the field of edible oil production. Background technique [0002] Rapeseed oil is what we call rapeseed oil, also known as rapeseed oil and coriander oil. It is squeezed out of rapeseed. It is one of the main edible oils in China. Rapeseed oil is golden or brownish in color and has a certain pungent smell. The folk citation is called "green smell". This smell is caused by a certain amount of mustard ring, but the special quality rapeseed does not contain this substance. The seeds (oil content of 22% -49%, average 40%) of cabbage type rape and cabbage type oil lai, containing 21%-27% protein and about 1% phospholipid, are one of the main edible oils in China. The existing production process of fried seed rapeseed oil has the problems of toxic residue and low oil yield. Summary of the invention [0003] The purpose of the present invention is to provide a rapesee...
