Problems solved by technology

[0004] Currently, barley wine and barley biscuits are the main products on the market. However, barley wine cannot be popularized. It is not easy for the elderly and children to drink, and it is not easy for young and middle-aged people to drink too much. In recent years, there are barley wine as raw materials. tea products, but most of them use highland barley grains as raw materials, which are usually fed directly without extraction. There are also researches on the extraction methods of highland barley bran extracts, but most of them use more acid-base and other chemical reagents, which are harmful to drinks. The taste has a greater influence

Embodiment 1

[0029] Example 1, the highland barley grains are screened and cleaned through the grains to remove impurities such as sediment, stones, and stalks; 100Kg of highland barley grains are ground through a noodle mill three times to obtain 70Kg of highland barley flour and 30Kg of highland barley bran; The bran is irradiated with microwaves, and the temperature of the highland barley bran is irradiated at 100°C for 5 minutes;

[0030] For the first extraction, take 30Kg of highland barley bran after microwave irradiation, add 0.15Kg of α-amylase and stir evenly, 180Kg of deionized water, stir and reflux at 100°C for 2h, the stirring speed is 300r / min, and centrifuge to obtain the above Clear liquid and residue, the rotating speed is 4000r / min, and the time is 20min;

[0031] For the second extraction, take the residue obtained from the first extraction and add 0.15Kg of α-amylase, stir evenly, add 180Kg of deionized water, stir and reflux at 100°C for 2h, the stirring speed is 300r...

Embodiment 2

[0034] Example 2, the highland barley grains are screened and cleaned through the grains to remove impurities such as sediment, stones, straws, etc.; 50Kg of highland barley grains are ground through a noodle mill three times to obtain 35Kg of highland barley flour and 15Kg of highland barley bran; The bran is irradiated with microwaves, and the temperature of the highland barley bran reaches 95°C for 2 minutes;

[0035] Take 15Kg of highland barley bran after microwave irradiation, add 0.04Kg of α-amylase and stir evenly, add 60Kg of deionized water, stir and reflux at 97°C for 2h, the stirring speed is 250r / min, and obtain the supernatant and residue after centrifugation , the speed is 3500r / min, and the time is 10min;

Abstract

The invention provides a preparation method of a highland barley bran beverage and relates to the technical field of highland barley processing. The method comprises the following steps: preliminary treatment, crushing, microwave wall breaking, three times of extraction of deionized water, centrifugal separation, filtration, precipitation, sterilization, filling and the like. The method has the benefits that: the beverage prepared with the method is rich in multiple nutrients such as dietary fiber, glucan, vitamins and the like; only deionized water is used for extraction, no any organic solvent or acid base reagent is used, the extraction is natural, and no harmful substances are remained; meanwhile, an extraction method is environmentally friendly, and no waste water, waste gas or otherharmful substances are discharged to pollute the environment; by using the highland barley bran as a raw material to prepared the beverage, local resource advantages can be translated into economic advantages, income of farmers and herdsmen is increased, the highland barley bran is turned into treasure, and the comprehensive utilization of highland barley resources is realized; the process is simple, the industrialization is easy to achieve, and the price of raw materials is low. As a result, the production cost is low, and the beverage has better market competitiveness.

Description

technical field [0001] The invention relates to the technical field of highland barley processing, in particular to a preparation method of highland barley bran beverage. Background technique [0002] Highland barley, also known as naked barley, is a special grain produced in the Qinghai-Tibet Plateau region of my country, with a cultivation history of 3,500 years. Qinghai highland barley in the alpine region of the Qinghai-Tibet Plateau is a non-polluting characteristic grain with an altitude of 2600-3000 meters, sufficient sunlight, arid climate, large temperature difference between day and night, and an annual average temperature of 3.3°C. Highland barley has high nutritional content, and the total fiber and soluble fiber content are higher than other cereal crops. At the same time, it is also rich in unsaturated fatty acids such as oleic acid, linoleic acid, and linolenic acid, and rich in vitamin C, vitamin E, and vitamin B. family and rich in trace elements: iron, cop...
