Problems solved by technology

Highland barley starch has a unique composition, generally containing 74-78% amylopectin, and has poor processability. In the traditional production and eating process, highland barley has many edible forms, such as highland barley tsampa, highland barley wine, and highland barley oatmeal, but it is made of highland barley Nutritious, easy-to-eat powder mix first

Embodiment 1

[0016] A preparation method of highland barley powder, comprising the steps of:

[0017] 1) Screen high-quality highland barley, remove stones and wash, and remove dust and impurities in highland barley;

[0018] 2) Put the selected highland barley into the flow dryer for drying, the drying temperature is 40°C, and the drying time is 60 minutes;

[0019] 3) Put the dried highland barley into a grinder for crushing, and the particle size of the highland barley powder obtained after crushing should reach more than 100 mesh;

[0020] 4) Take 65 parts of highland barley flour and 35 parts of rice flour in parts by weight, add them into a mixer for mixing, and obtain fully mixed materials;

[0021] 5) Use twin-screw extrusion to extrude and expand the material. The twin-screw extruder is divided into five zones for temperature treatment, which are 60°C, 140°C, 150°C, 150°C and 145°C, and the feeding amount of the material is 25kg / h, the added moisture is 12%, and the cutting rat...

Abstract

The invention provides a preparation method for highland barley dissolving powders and belongs to the field of food processing. Specifically, the highland barley is carefully chosen, cleaned, dried in a dryer and crushed in a pulverizer to prepare highland barley powders. After that, 60-70 weight parts of highland barley powders and 30-40 weight parts of rice flours are mixed up in a feed mixer and puffed in a twin screw extruder. The puffed highland barley is put into a fluidized bed to be dried, extruded by a tablet press, cooled and packaged. Due to the adoption of the above method, the defect in the prior art that the highland barley is not easy to process and mold due to the existence of amylopectin and the low content of gluten in the highland barley can be overcome. Highland barley dissolving powders prepared through the above method are brewed in boiled water to form a crisp and delicious highland barley paste. Therefore, not only the quality and the nutrient of the highland barley are maintained, but also the highland barley dissolving powders are convenient to take. The highland barley dissolving powders are suitable for the mass consumer. Meanwhile, the method is simple in process, high in mechanized level, suitable for large-scale industrial production and wide in popularization value.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a method for preparing highland barley reconstituted powder. Background technique [0002] Highland barley (Hordeum vulgare L.var.nudum hook.f.) It is the collective name for multi-row bare barley in the Qinghai-Tibet Plateau region of my country. It is also called Yuanmai, Huaimai, rice barley or naked barley in other producing areas. It is a special type of barley and belongs to the Gramineae wheat family in plant taxonomy. Barley is one of the varieties of barley. The nutritional content of highland barley contains 339 calories per 100 grams, 75 grams of carbohydrates, 1.5 grams of fat, 8.1 grams of protein, and 1.8 grams of cellulose. Thiamine (Vitamin B1) 0.32mg, Riboflavin (Vitamin B2) 0.21mg, Niacin 3.6mg; Vitamin E 0.25mg. The average content of β-glucan in highland barley is 6.57%, which is the highest β-glucan among wheat crops in the world, and is 50 times th...
