Embodiment 1

[0024] Take 100 kilograms of flaxseeds, remove impurities after cleaning, and obtain 96 kilograms of pure flaxseeds, fry them in an electric frying pan for 20 minutes, and obtain 90 kilograms of dry flaxseeds, and obtain 55 kilograms of flaxseed kernels through peeling and separation equipment, Use crushing equipment to crush to 6-20 mesh, then fry in an electric frying pan for 5 minutes, immediately pack the linseed kernel powder with a filter cloth, put it into a hydraulic oil press, and squeeze it under a pressure of 30MPa to obtain 32 kg of oil. After being filtered by a plate and frame filter, it was naturally precipitated for two days to obtain linseed oil. After testing, the color: Y40, R3.0; moisture and volatile matter 0.08%; insoluble impurities 0.04%; acid value 0.85mg / g; All meet or exceed the quality indicators of GB / T8235-2008 pressed first-grade linseed oil (color: Y45, R4.5; moisture and volatile matter 0.1%; insoluble impurities 0.05%; acid value 1.0mg / g; pero...

Embodiment 2

[0026] Take 100 kilograms of flaxseeds, remove impurities through cleaning, and obtain 96 kilograms of pure flaxseeds. Fry them in a frying pan on high heat for 1 minute to obtain 90 kilograms of dry flaxseeds. After peeling and separating equipment, 55 kilograms of flaxseed kernels are obtained. Use crushing equipment to crush to 6-16 mesh, then fry in a fire frying pan for 30 seconds, immediately pack flaxseed kernel powder with a filter cloth, put it into a hydraulic oil press, and squeeze it under a pressure of 60MPa to obtain 34 kg of oil. After filtering through a fine filter, it is naturally precipitated for one day to obtain linseed oil. After testing, the color: Y45, R3.0; moisture and volatile matter 0.07%; insoluble impurities 0.03%; acid value 0.8mg / g; All reached or surpassed the quality index of GB / T8235-2008 pressed first-grade linseed oil (the standard is the same as that of Example 1). Alpha-linolenic acid 58.4%.

Embodiment 3

[0028] Take 100 kilograms of flaxseeds, remove impurities after cleaning, and obtain 96 kilograms of pure flaxseeds, fry them in an electric frying pan for 15 minutes, and obtain 92 kilograms of dry flaxseeds, and obtain 56 kilograms of flaxseed kernels through peeling and separation equipment, Use crushing equipment to crush to 6-20 mesh, then fry in an electric frying pan for 8 minutes, pack the linseed kernel powder with a filter cloth, put it into a hydraulic oil press, and squeeze it under a pressure of 55MPa to obtain 33 kg of oil, and filter it with a centrifuge After one day of natural precipitation, linseed oil is obtained. After testing, the color: Y45, R2.0; moisture and volatile matter 0.08%; insoluble impurities 0.03%; acid value 0.45mg / g; All reached or surpassed the quality index of GB / T8235-2008 pressed first-grade linseed oil (the standard is the same as that of Example 1). Alpha-linolenic acid 60.2%.

Abstract

The invention discloses linseed kernel oil, which is extracted by pretreating and peeling linseed and taking linseed kernel as a raw material. A production method of the linseed kernel oil comprises the following steps: cleaning and drying linseed, separating peel and kernel; crushing, cooking the linseed kernel and squeezing out oil; and filtering and precipitating to obtain a finished product. The invention provides brand new edible oil. The processing technique of the product does not add any chemical reagent and is green and pollution-free, the product has no any chemical pollution, and the processing of the product is not subjected to high temperature, keeps alpha-linolenic acid in the linseed, and enables the content of the alpha-linolenic acid of the product to reach about 60 percent. The content of crude protein in byproduct, namely linseed kernel cake is improved by 10 percent compared with that of linseed cake and reaches about 43 percent, and the anti-nutritional factors are greatly reduced, widen the application of the linseed kernel cake and improve the additional value of processing. The product is novel, and the processing technology is mature, has high oil extraction rate and is easy to popularize.

Description

technical field [0001] The invention belongs to the technical field of edible oil processing, in particular to a linseed oil and a production method thereof. Background technique [0002] Flax is an annual herb. Flax is divided into flax for oil and flax for fiber. Flax for oil is also called flax. In my country, flax for oil is mainly distributed in Inner Mongolia, Shanxi, Hebei, Gansu, Ningxia and Xinjiang. Flaxseed is the seed of flax, and the oil obtained from flaxseed is called flaxseed oil. Linseed oil contains more than 90% unsaturated fatty acids, of which α-linolenic acid accounts for about 50%. α-linolenic acid, as the parent of omega-3 unsaturated fatty acids, is an important unsaturated fatty acid with active ingredients. It has a good preventive effect on cardiovascular and cerebrovascular diseases, which has become a recognized theory in the medical and nutritional circles. α-linolenic acid has been confirmed to have obvious inhibitory effect on more than 4...
