[0003] At present, the deep processing products of highland barley mainly focus on the research on the extraction process of β-glucan. The product is single. Although the remaining by-products have high nutritional value, they are only used as simple feed or discarded. Therefore, the utilization rate of highland barley is not high. not tall

Embodiment 1
[0024] Embodiment 1 A kind of technique that continuously extracts multiple products from highland barley, comprises the following steps:
[0025] (1) Raw material handling:
[0026] The raw material of highland barley is the mature naked barley from the cultivated barley (Hor-detl11 sctivum) of the genus Hordeun. Weigh 50 kg of cleaned and dried highland barley, grind it with an FMZ-278 noodle mill produced by Dahua Machinery Factory, Linyi East District, Shandong, and pass through a 200-mesh sieve to obtain 35 kg of highland barley flour and 15 kg of highland barley bran.
[0027] (2) Extraction of highland barley starch and protein powder:
[0028] First, 5 kg of the highland barley flour gained in step (1) is placed in a 100L stainless steel mixing tank, and 0.05 to 0.15% of the aqueous sodium hydroxide solution is added according to its weight-to-volume ratio of 1: 8 to 1: 40 to stir, and after stirring for 30 minutes, , stand at room temperature for 8-20 hours, centrif...
Embodiment 2
[0041] Embodiment 2 A kind of technique that continuously extracts multiple products from highland barley, comprises the following steps:
[0042] (1) Raw material processing: take 50 kg of dried highland barley that has been cleaned, grind it with a flour mill, and pass through a 200-mesh sieve to obtain 35 kg of highland barley flour and 15 kg of highland barley bran.
[0043] (2) The extraction of highland barley starch and protein powder is the same as in Example 1.
[0044] (3) Extraction of highland barley bran oil:
[0045] First put 5 kg of highland barley bran in a stainless steel tank, add petroleum ether (30-60) to cold soak for 8-24 hours according to its weight-to-volume ratio of 1:10 to 1:30, then use petroleum ether to permeate and rinse, and collect the washing liquid; then place the eluent in a rotary evaporator to recover the petroleum ether in the eluent at a temperature of 30-45°C; finally place it in a DHG9203A electric heating constant temperature blast ...

Abstract
The invention relates to a process for continuously extracting a plurality of products from highland barley, which comprises the following steps: (1) pulverizing highland barley raw material and screening highland barley flour and highland barley bran; (2) extracting and centrifugalizing the highland barley flour by alkaline solvent, collecting supernate and depositing and extracting albumen powder by acid; washing, freezing and drying the sediment at low temperature to obtain highland barley starch; (3) after the highland barley bran is extracted by a supercritical carbon dioxide technology or quenched by small polar solvent, obtaining highland barley bran oil; (4) after the degreased bran is ultrasonically extracted or stewed and centrifugalized by taking water as solvent, respectively obtaining powder containing highland barley beta-glucan and concentrated solution containing highland barley flavone and amino acid; and (5) after residues obtained in the step (4) are dried and pulverized in an ultramicro way, obtaining highland barley water insoluble fiber albumen powder. The process can continuously obtain six highland barley deep-processing products, effectively improves the utilization ratio of the highland barley and increases the utilization value of the highland barley.
Description
technical field [0001] The invention relates to a processing technology of highland barley products, in particular to a technology for continuously extracting various products from highland barley. Background technique [0002] Highland barley is a kind of barley, also known as naked barley and Yuanmai. It is commonly called highland barley in Tibet and Qinghai. It is the main food crop of the Tibetans, and it can be used to make tsampa and highland barley wine. The perennial sown area and total output of highland barley account for 55-60% of the total sown area and total output of Tibet's grain respectively, and the total output is about 600,000 tons. Highland barley is rich in β-glucan, which is the highest β-glucan among wheat crops in the world; highland barley also contains dietary fiber, pullulan, protein, rare nutrients such as thiamine (vitamin B1 ), riboflavin (vitamin B2), nicotinic acid, vitamin E, these substances have a positive effect on the promotion of huma...
