Technical Field

The invention relates to the technical field of premixed flour, in particular to a method for preparing coarse cereal premixed flour.

background

in recent years, along with the development of economy and social progress, people are increasingly conscious of improving quality of life and health, people are aware that people have no good taste as compared with other people, because of refined eating habits, people are easy to have insufficient intake of dietary fibers, vitamins, minerals and bioactive substances of human bodies, and intake of amino acid composition is unbalanced, so that various coarse cereals deeply love people, and people enjoy coarse cereals in various ways, such as coarse cereal porridge, coarse cereal fine dried noodles, coarse cereal bread and the like. Among them, the minor cereal bread is more and more popular among people.

The coarse cereals generally refer to all food crops which can be eaten by people except large food crops such as wheat, rice and the like, and contain nutrient substances such as protein and carbohydrate which are required by normal physiological activities of human bodies, and nutrient elements which can regulate functions of the human bodies, such as dietary fibers, vitamins, mineral substances (particularly trace elements such as iron and zinc) and antioxidant substances. In recent years, the research of the mixed application of various coarse cereals in the development of novel coarse cereal bread becomes a hotspot

The method is characterized in that the coarse cereal bread is produced by self-preparation in commercial production or home production, namely, the coarse cereal bread is produced by self-preparation of various coarse cereals, flour and other raw materials through the processes of raw material treatment, raw material blending, flour mixing, fermentation, cutting into pieces, proofing, baking and the like. The mode of making the coarse cereal bread by self-batching in the prior art has the defects of time consumption, complexity and low production or making efficiency, and is very inconvenient for commercially producing the coarse cereal bread or making the coarse cereal bread at home. The premixed powder is prepared by selecting different kinds and characteristics of powdery raw materials and different formulas, adding different other auxiliary components, and fully and completely mixing by advanced physical, chemical, biological and other technologies. The premixed flour has the characteristics of convenience, nutrition and functionalization, can provide a fool food making step, saves labor, labor and cost, reduces the specialty, the technicality and the failure rate of finished product making, improves the production efficiency and the yield while ensuring the quality, and is convenient to use and store after being opened. Therefore, the preparation of the coarse cereal premixed flour is very necessary.

The bread coarse cereal premixed flour in the market at present contains various additives to prolong the shelf life, eggs, water, grease, yeast and the like are required to be added when the bread coarse cereal premixed flour is used, certain inconvenience is brought to use, the coarse cereal premixed flour also has the technical problems of complex preparation process, high preparation cost and unbalanced nutrition, and the bread baked by the bread coarse cereal premixed flour has taste.
