Embodiment Construction

[0007] (1) Raw material screening and billet making

[0008] The impurity in the raw material is removed by means of air separation with a specific gravity machine, and flax (flax) seeds are crushed and poured into a material cylinder by a rolling mill method, and nitrogen gas is introduced into the material cylinder at the same time.

[0009] (2) Oil steaming and frying, nitrogen protection cooling

[0010] Put the raw material obtained in the step (1) into the steaming wok for steaming and frying, and control the steaming temperature at 100°C to 120°C by controlling the amount of steam in the steaming wok, steam for 30 minutes and then pour into the Cool the container under nitrogen.

[0011] (3) Nitrogen is introduced, and flax (flax) seed crude oil is initially pressed

[0012] Send the raw materials obtained in step (2) into the oil press for oil extraction. Nitrogen gas is introduced into the feeding port along the feeding direction, and the amount of nitrogen gas fee...

Abstract

Disclosed is a method for producing flax (benne) seed oil under nitrogen protection, belonging to the technical field of grain and oil processing. The invention specifically relates to a processing and production method for flax (benne) seed oil under nitrogen protection. According to the invention, in order to increase the content of alpha-linolenic acid in flax (benne) seed oil and prevent or reduce oxidation of alpha-linolenic acid in the production process of flaxseed oil, all the production links are carried out in the presence of nitrogen and light-tight ceramic bottles are employed to subpackage flax (benne) seed oil (PET bottles are not used so as to avoid the oxidation of alpha-linolenic acid under irradiation of sunlight) besides the adoption of conventional method of controlling squeezing temperatures (no more than 90 DEG C), thereby solving the problems existing in the conventional processes for producing flax (benne) seed oil that the functional component alpha-linolenic acid in the product is oxidized and the value of flaxseed oil is reduced due to no control of the influence of oxygen on flaxseed oil.

Description

technical field [0001] The invention belongs to the technical field of grain and oil processing, and in particular relates to a processing and production method for processing linseed oil with nitrogen protection in the whole process of linseed oil processing. Background technique [0002] The oil content of flax (flax) seeds is generally about 40%, and the content of unsaturated fatty acids in flax (flax) oil is as high as 90%, especially the content of α-linolenic acid is 45% to 60%. Flax (flax) seed is the largest resource of α-linolenic acid, its content is about dozens of times that of animal oils such as pigs, cattle, and sheep, more than 5 times that of rapeseed oil and soybean oil, 2.5 times that of marine fish, and shellfish 1.5 times that of perilla seed oil, but the planting area is dozens of times that of perilla seed oil. α-linolenic acid is an essential fatty acid that is necessary for the growth and development of animals, but cannot be synthesized in animals...
