Abstract
The invention discloses a production method of oat flour with good stability and instant solubility, which comprises the following steps: oat, deionized water, an enzyme preparation, nutrient powder and Chinese medicinal liquid. The oat flour with good stability and instant solubility is obtained by pretreating oat grains, baking and crushing, size mixing and saccharifying, adjusting the pH value, performing centrifugal separation, and finally concentrating and drying. Inorganic salt is added step by step to adjust the pH value of the solution in the enzymolysis stage, so that the soluble substance has better solubility in the powdery state; by optimizing the enzymolysis scheme, the enzymolysis product is more soluble in water and has better stability; the enzymolysis liquid is separated by a centrifugal machine, insoluble substances are separated out, soluble substances are reserved, and the stability of the oat flour is improved; through the drying by using the low-temperature vacuum belt-type dryer, the oat pulp forms a porous cellular structure during low-temperature evaporation, and the solubility of the oat flour is increased.
Description
Technical Field
The invention belongs to the field of food processing, and particularly relates to a production method of oat flour with good stability and instant solubility.
Background
In recent years, plant-based products represent plant-based beverages with sustainable and environmentally-friendly concepts, and gradually enter the public field of vision from the small-public market due to the delicious and unique mouthfeel of the plant-based beverages. The plant-based beverage is not only an innovation of a beverage product, but also represents a worried natural, green and innovative life concept. Oats are the most representative dietary source rich in balanced nutrition in vegetable protein, and are rich in vegetable protein, unsaturated fat, carbohydrate and rich dietary fiber. Plant-based oat beverages are accompanied by the popularity of OATLY products, with ready-to-drink oat beverages and cafe bushel oat beverages beginning to be popular worldwide. The plant-based oat beverage is a pure natural green formula, does not contain lactose, is suitable for people with lactose intolerance, does not contain any animal fat and soybean product, does not contain estrogen, does not have transgenic risk, and has 0 cholesterol.
At present, oat flour production methods mainly comprise two methods, one is baking superfine pulverized oat flour, baked oat flour for short, and the other is enzymolysis of oat flour by enzyme, enzymolysis of oat flour for short. Baked oat flour has a strong flavor but poor solubility and is not suitable for beverage applications. The enzymolysis oat flour has slightly light flavor but good solubility, but most of oat flour on the market has good solubility, but is easy to be burnt into a tube when being subjected to a UHT sterilization process during the application of the beverage, the temperature difference is large, continuous production cannot be realized, and the application of the oat flour in the beverage industry is limited.
Disclosure of Invention
The invention aims to provide a method for producing oat flour with good stability and instant solubility.
The technical problems to be solved by the invention are as follows:
1. two methods for producing the oat flour are seen, the baked oat flour has poor solubility and cannot be applied to beverages, the existing enzymatic oat flour in the market has poor stability, UHT (ultra Heat treated) can generate a pipe pasting phenomenon during the production of the beverages, and continuous production cannot be realized.
2. In the prior art, the homogenizing saccharification equipment used in the oat flour production process has the problems of single function, complex operation, insufficient homogenization and the like.
The purpose of the invention can be realized by the following technical scheme:
a production method of oat flour with good stability and instant solubility comprises the following raw materials: oat, deionized water, an enzyme preparation, nutrition powder and Chinese medicinal liquid.
The enzyme preparation is a mixture consisting of 4-8u/g of beta-glucose, 8-16u/g of pullulanase, 4-8u/g of alpha-amylase and deionized water, wherein the ratio of the beta-glucose to the pullulanase to the alpha-amylase to the deionized water is (2-5): 2-4: 3-8: 15-20.
The preparation method of the nutrition powder comprises the following steps:
cleaning and slicing 18-45 parts of pumpkin, 4-16 parts of Chinese yam, 12-29 parts of tremella, 6-35 parts of red bean and 5-20 parts of red date, then putting the slices into a baking oven, baking the slices for 8-15min at the temperature of 110 ℃, completely cooling the slices, grinding the slices into powder by using a refiner, and sieving the powder by using a sieve of 90-100 meshes to obtain the nutritional powder.
The preparation method of the traditional Chinese medicine liquid comprises the following steps:
cleaning 5-15 parts of Chinese herbal medicine raw materials, wherein the Chinese herbal medicine raw materials comprise 25-45 parts of bulbus fritillariae cirrhosae, 20-40 parts of succus bambusae, 15-35 parts of cortex mori, 10-25 parts of caulis polygoni multiflori, 5-15 parts of eclipta prostrata and 5-8 parts of cordyceps cicadae; then crushing the cleaned Chinese herbal medicine raw materials to 50-100 meshes by a crusher, adding 50-120 parts of deionized water, decocting at 85-110 ℃ for 2-4h, cooling, and filtering to obtain a filtrate, namely the Chinese medicinal liquid.
The production method of the oat flour comprises the following steps:
