Description

Corn meal replacement powder capable of promoting growth of intestinal probiotics and preparation method thereof Technical Field The invention belongs to the technical field of foods, and particularly relates to corn meal replacement powder capable of promoting growth of intestinal probiotics and a preparation method thereof. Background The corn has rich corn dietary fiber, and the high-quality corn dietary fiber powder is obtained by carrying out high-quality treatment on the dietary fiber component, and the content of the soluble dietary fiber is very high. Numerous studies have shown that ingestion of dietary fiber helps promote the growth of probiotics in the gut. Meanwhile, most of the energy in the corn is derived from starch in corn seed endosperm, so that the starch content in the corn is reduced, and the energy taken in eating the corn can be reduced. In the aspect of food processing and manufacturing, corn is rich in nutrition and health care factors, but has poor taste when taken alone, so the edible value of the corn is not fully developed. Probiotics are non-pathogenic living bacteria, including bifidobacteria, lactobacilli, yeasts, etc., and a paper published by Dora i.a. Pereira et al in APPLIED AND Environmental Microbiology shows that lactic acid bacteria produce Bile Salt Hydrolase (BSH) to cause bile salts to lose conjugation, and under acidic (pH < 6.0) conditions, the hydrolysis of small intestinal bile salts is promoted, and the unconjugated bile salts and cholesterol form a complex to co-precipitate, thereby promoting the transfer of food-borne cholesterol to feces. At present, most of meal replacement powder raw materials in the market are red beans, pearl barley, konjak and the like, and most of the production processes are that the raw materials are crushed and then baked at low temperature, and the crushed raw materials are mixed with cellulose powder to obtain the finished product. For example, CN105995563a discloses a red bean coix seed meal replacement powder, which still contains a large amount of starch in the product, and cannot reduce the energy taken in during eating. Disclosure of Invention In order to overcome the defects of the prior art, the invention aims to provide the corn meal replacement powder capable of promoting the growth of intestinal probiotics and the preparation method thereof, so as to solve the problems that the starch content in the existing meal replacement powder is high and corn is not suitable to be used as a main material of the meal replacement powder. In order to achieve the above purpose, the technical scheme adopted by the invention is as follows: The corn meal replacement powder consists of 76.9 to 88.5 weight percent of enzymolysis freeze-dried corn powder, 10 to 20 weight percent of yam powder, 0.3 to 0.7 weight percent of stevioside, 0.4 to 0.8 weight percent of propylene glycol alginate, 0.4 to 0.8 weight percent of xanthan gum and 0.4 to 0.8 weight percent of sodium carboxymethyl cellulose. The preparation method of the corn meal replacement powder comprises the following steps: A. Preparing enzymolysis freeze-dried corn flour, comprising: (1) Mixing corn flour and water according to a mass ratio of 1:3-5, and uniformly stirring and mixing to obtain a mixed material; (2) Adding anhydrous calcium chloride accounting for 0.25 percent of the total weight of the mixed materials and high-temperature resistant alpha amylase accounting for 0.3 to 0.8 percent into the mixed materials, wherein the enzymolysis time is 10 to 30 min, and the enzymolysis temperature is 65 to 85 ℃; (3) Suction filtration, namely suction filtration is carried out on enzymolysis liquid, meanwhile, water is added to wash sediment, and finally filtrate is discarded to take sediment; (4) Freeze drying, namely placing the precipitate in a refrigerator with the temperature of minus 75 ℃ to minus 80 ℃ and the like to freeze for 11.5 to 12.5 hours, and then drying in vacuum for 35 to 37 hours; (5) Crushing, namely crushing the freeze-dried material to obtain enzymolysis freeze-dried corn flour; B. and (3) preparing meal replacement powder, namely uniformly stirring and mixing the obtained enzymolysis freeze-dried corn meal, yam powder, stevioside, propylene glycol alginate, xanthan gum and sodium carboxymethyl cellulose to obtain the meal replacement powder, wherein the meal replacement powder has the effects of promoting the growth of intestinal probiotics and improving the intestinal environment. A preferred embodiment of the invention is: A. Preparing enzymolysis freeze-dried corn flour, comprising: (1) Mixing corn flour and water according to a mass ratio of 1:4, and uniformly stirring and mixing to obtain a mixed material; (2) Adding anhydrous calcium chloride accounting for 0.25 percent of the total weight of the mixed materials and high-temperature resistant alpha amylase accounting for 0.7 percent of the total weight of the mixed materials into the mixed materials, wher
