Embodiment 1

[0020] figure 1 It is a schematic flowchart of a production method of a defatted highland barley product provided in Example 1 of the present invention. like figure 1 As shown, the method includes steps S101-S103:

[0021] In step S101, the highland barley bran is pulverized by a pulverizer and passed through a 400-mesh sieve several times to obtain 20-50 kg of highland barley bran; respectively put 20-50 kg of highland barley bran and carbon dioxide with a purity of 99.9% into the pressure of 20-25 Mpa carbon dioxide supercritical extraction kettle.

[0022] Preferably, the pressure of the extraction tank is 20-25Mpa.

[0023] Step S102, extracting in a carbon dioxide supercritical extraction kettle at a temperature of 40° C. to 50° C. for 0.5 h to 3 h to obtain an extract, which includes a carbon dioxide fluid containing crude oil of highland barley bran and defatted highland barley bran.

[0024] In step S103, the carbon dioxide fluid containing crude oil of highland ba...

Embodiment 2

[0031] After the highland barley bran is pulverized by a pulverizer and 3 passes through a 400 mesh sieve, 30kg of sieved highland barley bran and carbon dioxide with a purity of 99.9% are put into a carbon dioxide supercritical extraction kettle with a pressure of 25Mpa; the carbon dioxide flow rate is 18kg / h. The carbon dioxide supercritical extraction kettle is extracted at a temperature of 50° C. for 3 hours to obtain the extract, which includes the carbon dioxide fluid containing the crude oil of highland barley bran and the defatted highland barley bran; the carbon dioxide fluid containing the crude oil of highland barley bran flows into the In a separation tank connected to a carbon dioxide supercritical extraction tank; the defatted highland barley bran is obtained at the bottom of the extraction tank.

[0032] Preferably, after obtaining the defatted highland barley bran, before detecting the defatted highland barley bran, the defatted highland barley bran is treated...

Embodiment 3

[0036] After the highland barley bran is pulverized by a pulverizer and passed through a 400 mesh sieve for 4 times, the highland barley bran after sieving and the carbon dioxide with a purity of 99.9% are put into a pressure of 20Mpa respectively in a carbon dioxide supercritical extraction kettle of 20Mpa; It is 25kg / h. The carbon dioxide supercritical extraction kettle is extracted at a temperature of 40°C for 2 hours to obtain the extract, which includes a carbon dioxide fluid containing the crude oil of highland barley bran and defatted highland barley bran; the carbon dioxide fluid containing the crude oil of highland barley bran flows into the In a separation tank connected to a carbon dioxide supercritical extraction tank; the defatted highland barley bran is obtained at the bottom of the extraction tank.

[0037] Preferably, before detecting the defatted highland barley bran, the defatted highland barley bran is treated in a boiling water bath at 89° C. for 2 hours. ...

Abstract

The invention relates to a degreased highland barley product and a production method. The production method comprises the following steps: crushing highland barley through a crusher and sieving for many times, separately putting 20-50kg of sieved highland barley and carbon dioxide, the purity of which is 99.9%, in a carbon dioxide supercritical extraction kettle, the pressure of which is 20-25Mpa; performing extraction for 0.5-3h in the carbon dioxide supercritical extraction kettle at 40-50 DEG C to obtain extract which comprises a carbon dioxide fluid containing highland barley coarse oil and a degreased highland barley product, wherein the carbon dioxide fluid containing highland barley coarse oil flows into a separation kettle connected to the carbon dioxide supercritical extraction kettle; and obtaining the degreased highland barley product from the bottom of the extraction kettle. According to the invention, grease in highland barley is removed through a carbon dioxide supercritical extraction process to obtain the degreased highland barley product. The degreased highland barley product is mild in process condition, non-toxic and harmless and free from residues, and has a far-reaching influence on the field.

Description

technical field [0001] The invention relates to the field of grain deep processing, in particular to a defatted highland barley product and a production method. Background technique [0002] Highland barley, Hordeum vulgare L. is a cereal crop of the genus Barley in the Poaceae family. It is widely planted as a food crop on the Qinghai-Tibet Plateau. The inner and outer glumes of the highland barley are separated, and the grains are exposed. It is also called naked barley, barley, and rice barley. Highland barley is one of the oldest grains in the world. Recently, naked barley has received a lot of attention because of its high nutritional value and rich dietary fiber. The output of highland barley in Tibet in 2011 was 620,000 tons, which is mainly used as food, while straw is mainly used as feed and fuel, which plays a very important role in people's life. Today, a variety of commercial products have been developed from highland barley, such as tsampa, biscuits, noodles, ...
