Embodiment 1

[0018] Embodiment 1: Get 500g of oats, add 2500g of soft water to carry out wet superfine grinding, then pass through a 300 mesh sieve, add soft water 5 times the weight of oat raw material to the slurry after superfine grinding, boil to make the starch in it gelatinize completely, Then cool to 50-60°C, enzymolyze the obtained slurry, the enzymolysis conditions are temperature 55°C, ph is neutral, add medium temperature α-amylase 15u / g raw material, enzymolysis 30min, then add β-amylase 100u / g g raw material, enzymatic hydrolysis for 30min; then add glucose isomerase 50u / g raw material, enzymatic hydrolysis for 30min. Heat the material after enzymolysis to 90-95°C and keep it warm for 5 minutes to inactivate the enzyme. Homogenization 400MP, second-stage homogenization 200MP, the homogenized material liquid is subjected to ultra-high temperature instantaneous sterilization at a temperature of 135°C for 10s, and canning after sterilization. The percentages involved in the expe...

Embodiment 2

[0019] Embodiment 2: Get 500g of oats, add 3000g of soft water to carry out wet superfine grinding, pass through a 300 mesh sieve, add soft water with 6 times the weight of oat raw material to the slurry after superfine grinding, boil to make the starch in it fully gelatinize, and then Cool to 50-60°C, enzymolyze the obtained slurry, the enzymolysis condition is temperature 50°C, ph is neutral, add medium temperature α-amylase 20u / g raw material, enzymolysis 20min, then add β-amylase 150u / g Raw material, enzymolysis for 20min; then add glucose isomerase 80u / g raw material, enzymolysis for 20min. Heat the material after enzymolysis to 90-95°C and keep it warm for 5 minutes to inactivate the enzyme. Homogenization 400MP, second-stage homogenization 200MP, the homogenized material liquid is subjected to ultra-high temperature instantaneous sterilization at a temperature of 140°C for 5s, and canning after sterilization. The percentages involved in the experiment are all mass perc...

Abstract

The invention relates to a method for preparing a whole oat healthy drink through wet process ultrafine grinding, belonging to the field of cereal deep processing. According to the method, oat is ground to be fine enough through wet process ultrafine grinding, the viscosity, stability and external property of the oat water system are improved by means of emulsification and homogeneity, so that the purpose of fully utilizing the oat is reached, and the prepared oat drink maintains all proteins, beta-glucan, mineral substances, vitamins and the like of the oat, furthermore, a part of the starch in oat is converted into glucose through enzyme reaction and is further converted into fructose, so that the content of glucose in the drink is low, but the sweetness of the drink is proper and saccharose or other sweetening agents do not need to be added, therefore, the whole oat healthy drink is rich in nutrients, has good fragrance and taste, and also has health care function. The method is scientific and reasonable, and can improve the comprehensive use value of oat resource and the economic benefit of food production.

Description

technical field [0001] The invention relates to a method for preparing an all-purpose oatmeal health drink by using wet superfine pulverization, and belongs to the field of grain deep processing. Background technique [0002] Oats, Poaceae, Oats are crops. From the perspective of plant taxonomy, they are divided into two types: bark oats and naked oats. my country's oats are mainly naked oats, and its output accounts for more than 90% of the total oats. The world produces more than 23.1 million tons of oats every year, and the main producing countries are Canada, the United States, China, Australia and EU countries. Oat is a crop with multiple uses, which can be used in feed, medicine, food, industrial raw materials and cosmetics. Oat is one of the best complete nutritional foods in cereals, rich in protein, minerals, vitamins, dietary fiber and unique saponins in cereal crops, etc. The protein and fat content in naked oats ranks first in cereal crops, and is essential for...
