Example Embodiment

[0023] Example 1

[0024] Take 100 kilograms of flaxseeds, remove impurities after cleaning, get 96 kilograms of pure flaxseeds, fry them in an electric frying pan for 20 minutes, get 90 kilograms of dry flaxseeds, and get 55 kilograms of flaxseed kernels by peeling and separating equipment. Use crushing equipment to crush to 6-20 mesh, then fry in electric frying pan for 5 minutes, immediately pack linseed kernel powder with filter cloth, put it into hydraulic oil press, press under the pressure of 30MPa, get 32 ​​kg of oil, use After being filtered by a plate and frame filter, it is naturally precipitated for two days to obtain linseed oil. After testing, 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; peroxide value 6.0 mmol / kg;...

[0025] Example 2

[0026] Take 100 kilograms of flaxseeds, remove impurities through cleaning, get 96 kilograms of pure flaxseeds, fry them in a hot wok for 1 minute, get 90 kilograms of dry flaxseeds, go through peeling and separation equipment to get 55 kilograms of flaxseed kernels, Pulverize it to 6-16 mesh with a pulverizing equipment, then fry it in a hot frying pan for 30 seconds, immediately pack the linseed kernel powder with a filter cloth, put it into a hydraulic oil press, and press it under a pressure of 60MPa to obtain 34 kg of oil. After being filtered by the fine filter, it is naturally precipitated for one day to obtain linseed oil. After testing, color: Y45, R3.0; moisture and volatile matter 0.07%; insoluble impurities 0.03%; acid value 0.8mg / g; All meet or exceed 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%.

Example Embodiment

[0027] Example 3

[0028] Take 100 kilograms of flaxseeds, remove impurities after cleaning, get 96 kilograms of pure flaxseeds, fry them in an electric frying pan for 15 minutes, get 92 kilograms of dry flaxseeds, and get 56 kilograms of flaxseed kernels by peeling and separating equipment. Pulverize it to 6-20 mesh with pulverizing equipment, then fry it in an electric frying pan for 8 minutes, pack the linseed kernel powder with filter cloth, put it into a hydraulic oil press, and press under a pressure of 55MPa to obtain 33 kg of oil, which is filtered with a centrifuge After a day of natural precipitation, flaxseed oil is obtained. After testing, color: Y45, R2.0; moisture and volatile matter 0.08%; insoluble impurities 0.03%; acid value 0.45mg / g; All meet or exceed 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...
