Abstract

The invention relates to a food processing method, in particular to a method for processing highland barley. The process flow of the method comprises: barley raw materials are subjected to impurity removal, seed grading, peeling, screening, polishing, oat wetting, enzyme digestion, heat preservation, temperature reduction, screening, drying, mixing, primary packaging and external packaging to obtain the finished product. The method has the following advantages that: the method adopts the simple processing process, particularly the enzyme killing process which can kill lipase, protease and amylase; after enzyme killing, the barley seed is piled together to keep warm for 6 hours so as to ensure the complete deactivation of the enzymes under the conditions of high temperature and high humidity, make the highland barley after enzyme killing easily cooked, improve taste, avoid the highland barley from oxydative spoilage and prolong the guarantee period. The processing method provides a useful way for developing the abundant barley resources in Qinghai.

Description

A kind of processing method of highland barley rice

Technical field

The present invention relates to a kind of food-processing method, specifically relate to a kind of processing method of highland barley rice.

Background technology

Highland barley mainly originates in the Qinghai-Tibet Platean, and is nutritious, the content of organics height, and wherein beta-glucan content is the highest.Beta-glucan can effectively be prevented and treated multiple diseases such as diabetes, hypertension.At present, biomedical boundary generally believes that beta-glucan has gut purge, regulates four big physiological functions such as blood sugar reduction cholesterol, raising immunity.Owing to the restriction that is subjected to multiple reasons such as traditional idea, kind, output, the methods of cultivation, processing eating habit, highland barley is many with wine brewing or widely edible with the form of zanba, roasted qingke barley flour as coarse cereals usually, and its green nourishing food value also is far from developing.

Summary of the invention

The technical problem to be solved in the present invention is at the deficiencies in the prior art, provides a kind of with the highland barley rice processing method of highland barley as green nourishing food.

The processing method of a kind of highland barley rice of the present invention is achieved by following technical proposals: the processing method of a kind of highland barley rice of the present invention, its technological process is that the highland barley raw material gets product through removal of impurities, seed classification, peeling, screening, polishing, wheat wetting, the enzyme that goes out, insulation, cooling, screening, oven dry, mixing, packing, external packing just, it is characterized in that: described seed classification is with multiple separator the disconnected grain of highland barley to be carried out classification by seed size, is divided into big seed and fine grain; Described peeling is to adopt skinning machine that the hullessbarley seed of classification is removed the peel processing, and the peeling rate remains on about 94%, collects skin and waits until the extraction beta-glucan; The described enzyme that goes out is to adopt steam treatment, and vapor (steam) temperature is to handle 20min more than 100 ℃; Handle 10min with the 0.24Mpa high-pressure water vapor; Go out behind the enzyme hullessbarley seed stack up insulation 6h; Spread the seed heap out cooling then; Screening after described insulation, the cooling is that the highland barley particle that will produce in the peeling process sifts out with separator; Described oven dry is by the food baking method hullessbarley seed to be dried, and makes the moisture in the hullessbarley seed be reduced to 11-12%; Described mixing is that highland barley rice is mixed in the ratio of 1:1-3 with rice; Described just packing, external packing are to pack by the specification requirement of commodity rice.

The processing method of a kind of highland barley rice of the present invention has following beneficial effect compared with prior art: the present invention has adopted simple machining process, particularly adopts the enzymatic process that goes out, and can kill lipase, protease and amylase; Going out keeps temperature 6h with the hullessbarley seed stack up behind the enzyme, and its effect is to guarantee enzymatic activity complete deactivation under higher temperature and high humidity, makes the highland barley Miyi boiling behind the enzyme that goes out, the improvement mouthfeel, and can prevent that the oxidation of highland barley rice from breathing out loses, and extends the shelf life.Highland barley after the processing of the processing method of a kind of highland barley rice of the present invention original shape of highland barley grain of can guaranteeing the quality can not destroyed the original nutritional labeling of highland barley, can be the wide approach that the abundant highland barley resource in exploitation Qinghai provides development and use.

The specific embodiment

Below in conjunction with embodiment the processing method technical scheme of a kind of highland barley rice of the present invention is further described.

Embodiment 1.

The processing method technological process of a kind of highland barley rice of the present invention is the highland barley raw material through removal of impurities, seed classification, peeling, screening, polishing, wheat wetting, comes enzyme, insulation, cooling, screening, oven dry, mixing, packing, external packing just to get product, described seed classification is with multiple separator the disconnected grain of highland barley to be carried out classification by seed size, is divided into seed seed and fine grain; Described peeling is to adopt skinning machine that the hullessbarley seed of classification is removed the peel processing, and the peeling rate remains on about 94%, collects skin and waits until the extraction beta-glucan; The described enzyme that goes out is to adopt steam treatment, and vapor (steam) temperature is to handle 20min more than 100 ℃; Handle 10min with the 0.24Mpa high-pressure water vapor; Go out behind the enzyme hullessbarley seed stack up insulation 6h; Spread the seed heap out cooling then; Screening after described insulation, the cooling is that the highland barley particle that will produce in the peeling process sifts out with separator; Described oven dry is by the food baking method hullessbarley seed to be dried, and makes the moisture in the hullessbarley seed be reduced to 11%; Described mixing is that highland barley rice is mixed in the ratio of 1:2 with rice; Described just packing, external packing are to pack by the specification requirement of commodity rice.
