Problems solved by technology

[0008] 2. Comprehensive loss of vitamin components
Natural linseed oil contains more than 80mg / 100g of vitamin E and rich carotenoids, but the vitamin E in refined linseed oil is reduced to less than 5mg / 100g, and almost all carotenoids are lost due to decolorization and deodorization
[0009] 3. Cause protein denaturation
[0010] 4. Reduce the viscosity of linseed gum

Embodiment Construction

[0023] Embodiment: In order to ensure the quality of cold-pressed linseed oil, the quality of raw material of linseed is strictly controlled at first. It is required that the raw materials must be cleaned up with a purity of over 99.5%. The raw materials cannot be wetted by water, because the raw materials that have been exposed to water will become moldy. The raw materials should not contain impurities such as rapeseed and bitter mustard, and should not contain metal, sand and stone energy sundries. The raw materials are best harvested in the same year, and old materials cannot be used.

[0024] 10,000kg of linseed raw materials must be tempered before being squeezed, and the moisture content of the raw materials should be controlled between 8-10%. The pressing process uses a twin-screw oil press. The raw materials are not fried or steamed before being squeezed, but directly squeezed at room temperature for one time. The maximum oil output temperature during pressing is c...

Abstract

The present invention provides a low temperature cold pressed method of a linseed oil, the main process includes: directly processing disposable press after cleaning, quenching and tempering the linseed raw material, the press oil yield is less than 80 DEG C. The wool oil refining process adopts drying method and physical absorption method, completely processing under the normal temperature. The preparing method wholly retains all kinds of nutritious components of the linseed oil, linseed protein, flaxseed gum and wood phenol components in the oil cake are not damaged, further developed and utilized. The oil cake after pressed is directly utilized as a food nutritious additive composition.

Description

technical field [0001] The invention relates to a production method of linseed oil, in particular to a production method of low-temperature cold pressing of linseed oil. Background technique [0002] Flax (commonly known as flax) is a traditional edible oil species in Northwest my country, and it is also one of the few oil crops rich in α-linolenic acid. Flaxseed (linseed) contains 38%-42% oil, of which α-linolenic acid content is about 57%, which is a typical omega-3 edible oil. At the same time, flaxseed also contains protein, edible gum, vitamins, lignans and other nutritional components, which have great development and utilization value. [0003] α-linolenic acid is the matrix of the omega-3 series of fatty acids. It has various health care functions for the human body. It is the most beneficial type of fatty acids for the human body. It is known as the core substance of life. Since the human body is indispensable and cannot be synthesized, it can only be supplemented...
