Embodiment 1

[0018] A process for preparing rapeseed oil by biological enzymatic method, comprising the following steps:

[0019] (1) Use a windmill to remove the ash debris lighter than the rapeseed first, and then sieve it with a coarse and fine sieve to remove the debris larger and smaller than the rapeseed, then put the rapeseed into the water and rub it gently with your hands After 5 minutes, remove the sludge covering the surface of the rapeseed, then fish out the rapeseed and dry it in the sun;

[0020] (2) Peel the rapeseed, and then grind for 5 minutes;

[0021] (3) The compound wall-breaking enzyme enzymolyzes the cell wall of rapeseed to promote the release of oil;

[0022] (4) Extract erucic acid by lead salt method, filter impurities, and obtain crude oil;

[0023] (5) Raise the rapeseed crude oil to 60°C, hydrate and degumming it for 8 minutes, then cool it to room temperature, then add activated carbon and keep stirring, and heat it with steam for 30 minutes, in a distilla...

Embodiment 2

[0028] A process for preparing rapeseed oil by biological enzymatic method, comprising the following steps:

[0029] (1) Use a windmill to remove the ash debris lighter than the rapeseed first, and then sieve it with a coarse and fine sieve to remove the debris larger and smaller than the rapeseed, then put the rapeseed into the water and rub it gently with your hands After 10 minutes, remove the sludge covering the surface of the rapeseed, and then remove the rapeseed and dry it in the sun;

[0030] (2) Dehull the rapeseed, then grind for 30 minutes;

[0031] (3) The compound wall-breaking enzyme enzymolyzes the cell wall of rapeseed to promote the release of oil;

[0032] (4) Extract erucic acid by lead salt method, filter impurities, and obtain crude oil;

[0033] (5) Raise the rapeseed crude oil to 70°C, hydrate and degumming it for 10 minutes, then cool it to room temperature, then add activated carbon and keep stirring, and heat it with steam for 40 minutes, in a disti...

Abstract

The invention discloses a technology for preparing rapeseed oil according to a biological enzyme method. The technology comprises the following steps: firstly, removing dust sundries lighter than therapeseeds from the rapeseeds by using a winnower, then sieving by using coarse and fine sieves to remove sundries larger or smaller than the rapeseeds respectively, then putting the rapeseeds into water, gently rubbing the rapeseeds for 5-10 minutes by hand, removing sludge covering the surface of rapeseeds, then fishing out the rapeseeds and drying the rapeseeds in sunlight; peeling the rapeseeds, and then grinding for pulping for 5-30min; enzymolyzing rapeseed cell walls by using composite lyticase to promote oil release; extracting erucic acid according to a lead salt method, and filteringimpurities to obtain crude oil; refining the crude rapeseed oil to obtain finished rapeseed oil. The rapeseed oil is produced according to the biological enzyme method and the erucic acid is extractedaccording to the lead salt method, so that the erucic acid content of the rapeseed oil is reduced, and thus the rapeseed oil is healthier to eat.

Description

technical field [0001] The invention relates to the technical field of edible oil processing, in particular to a process for preparing rapeseed oil by a biological enzymatic method. Background technique [0002] Rapeseed oil is commonly known as rapeseed oil, also known as rapeseed oil. It is sweet, pungent, and warm in nature. It can moisten dryness and kill insects, disperse fire pills, and reduce swelling and poison. The human body has a high absorption rate of rapeseed oil, which can reach 99%. Therefore, the unsaturated fatty acids such as linoleic acid and vitamin E and other nutrients contained in it can be well absorbed by the body, and have certain effects of softening blood vessels and delaying aging. Since the raw material for oil extraction is the seed of a plant, it generally contains a certain amount of seed phospholipids, which is very important for the development of blood vessels, nerves, and brain. Rapeseed oil contains little or no cholesterol, so people...
