preparation example Construction

[0013] Such as figure 1 As shown, a method for preparing highland barley β-glucan of the present invention is characterized in that the method comprises the following steps:

[0014] 1) Cleaning and crushing steps: remove impurities from the highland barley grains, wash and crush them, and pass through a 20-40 mesh sieve;

[0015] 2) Extraction steps: According to the ratio of material to water 1:6~10, gelatinize in water bath at 90°C for 2 hours, add α-amylase for enzymolysis for 30 minutes, filter the filtrate according to 40 mesh, and continue to filter the residue according to the ratio of material to water 1:3~ 6. Water bath at 90°C for 2 hours, filter according to 40 mesh to obtain the second filtrate, and continue to filter the residue according to the material-to-water ratio of 1:2-4, bathe in 90°C for 2 hours, filter to obtain the third filtrate, and combine the filtrates;

[0016] 3) Centrifugal extraction step: centrifuge at 4000 rpm for 10 minutes to remove starch...

Embodiment 1

[0020] The process route of a method for preparing highland barley β-glucan of the present invention is as follows:

[0021] 20—40 mesh, add α-amylase to remove starch

[0022] Highland barley (removing impurities) → Grinding—————————————————————————————————————————————————————————→

[0023] Adjust pH to 4.5, remove protein, ethanol, dry

[0024] Centrifugate————→centrifugation———→Centrant liquid adjusted to PH=7————→ sediment———→β-glucose

[0025] Sampling

[0026] Polycane products——→Separate packaging and sealing.

[0027] The process conditions adopted in the present invention are as follows: remove impurities from the highland barley grains, wash and pulverize them, pass through a 40-mesh sieve, gelatinize in a water bath at 90°C for 2 hours, add α-high temperature resistant amylase for 30 minutes, Filtrate (40 mesh) to obtain the filtrate, continue to use the ratio of material to water 1:3, bathe in 90°C water for 2 hours, filter (40 mesh) to obtain the second filtra...

Abstract

The invention relates to the field of food processing, in particular to a barley beta-glucan preparation method for extracting beta-glucan products from barley kernels endemic to Qinghai-Tibet Plateau. The preparation method comprises the following steps of: (1) riddling and crushing; (2) extracting; (3) centrifugally extracting; (4) acidifying; and (5) drying to obtain the beta-glucan products. The preparation method provided by the invention has the advantages that the adopted extracting technique is simple and is easy to operate, the required equipment is single, the used reagents are nontoxic, the waste materials generated in an extracting process can be used as stock food, the used ethanol can be recycled, water obtained after the ethanol is recovered can be reused, and no pollution is discharged in the whole extracting process, which is favorable for protecting the environment. The whole extracting process is free from danger, damage and pollution.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a method for preparing highland barley beta-glucan by extracting beta-glucan products from highland barley barley grains which are special products of the Qinghai-Tibet Plateau. Background technique [0002] β-glucan has the functions of lowering human cholesterol, blood lipid and blood sugar, and has anti-tumor effect, which has attracted the attention of countries all over the world. Japan, South Korea, Southeast Asia and other major rice producing countries, due to the lack of barley, oats and other food crops, need to import from the United States and Canada, which are rich in barley and oats, to produce β-glucan products as food additives. my country's food industry has also been engaged in the research of extracting β-glucan from barley, oats and other food crops, and the highland barley, which is mainly produced in the Qinghai-Tibet Plateau, has been found to be β-glucan thr...
