[0030] Further detailed description of the present invention: as figure 1 Shown, a kind of preparation method of buckwheat bread premix powder, take buckwheat bran as raw material, specifically comprise the following steps:

[0031] a. Buckwheat bran defatted

[0032] According to the ratio of buckwheat bran to ethyl acetate (w / w) of 1:8, soak buckwheat bran at 20-25°C for 3-5 hours, dry in a drying oven at 55-75°C for 1-3 hours, and wash with distilled water The remaining ethyl acetate is filtered by suction and then dried in a drying oven at 55-75°C for 1-3 hours to obtain buckwheat defatted bran;

[0033] b. Buckwheat defatted bran crushing

[0034] The above-mentioned buckwheat defatted bran is pulverized to 100-200 mesh by using an ultrafine pulverizer, and is set aside;

[0035] c. Buckwheat bran dietary fiber extraction

[0036] Add water to the above crushed buckwheat defatted bran at a ratio of 10:3~5 (w / w), then add amylase to hydrolyze for 1~3h, the hydrolysis t...

Abstract

The invention discloses a preparation method of buckwheat bread ready-mixed powder containing buckwheat bran dietary fiber and rutin, comprising the following steps: a. bran defatting; b. smashing; c. dietary fiber extracting; d. dry packing; e. rutin extracting; f. separating and purifying; g. vacuum-concentrating; h. quick-freezing; i. vacuum freeze-drying; j. packaging; and k. ready-mixed powder preparing. Compared with other ready-mixed powders, the ready-mixed powder prepared by the invention is added with the active nutrient extract of buckwheat, and the bread made thereof is safe to consume and has buckwheat dietary fiber and rutin; the long-term consumption of the bread can help to improve body immunity and enhance human health.

Description

technical field [0001] The invention relates to a preparation method of bread premix, more specifically relates to a preparation method of bread premix which takes buckwheat bran as raw material and is rich in buckwheat bran dietary fiber and rutin. Background technique [0002] Pre-mixed powder refers to the mixing of various powdery raw materials required for making bread, cakes and other flour-based foods to form a mixture. When making food such as bread, you only need to add water and stir it evenly to get the raw material of the product, which eliminates the purchase, batching, sieving, mixing and other processes of various raw materials in the production process, and not only shortens the production time of the factory process, but also convenient for consumers to make at home. [0003] The nutritional function of buckwheat has been proved by research, but the deep processing of buckwheat is still in the initial stage at home and abroad. Bread premix made from powder...
