Abstract
The invention relates to a method for producing an oat solid beverage, belonging to the manufacture field of solid beverages. The production method comprises the following steps: grinding oats into 60-80 meshes by a dry method; adding 3-15 times of water by mass in a pasting tank or a saccharifying tank provided with a stirrer; adding 5-20 thousand U / kg of high-temperature resistant amylase of oatpowder; heating to boil and keeping the temperature for 10-60min; lowering the temperature to 45-60 DEG C, adding 2-12 thousand U / kg of pectase of oat powder; filtering to obtain primary filter liquid and filter residual; adding 1-4 times of water in the filter residual; soaping for 10-40min for secondary filtering; merging the primary filter liquid and the secondary filter liquid; carrying out vacuum concentration until soluble solid matter reaches more than 40%; atomizing and drying to obtain the oat beverage power; adding 20-40% of auxiliary materials by weight of oat power; and palletizing to obtain the pellet oat solid beverage. The oat solid beverage produced in the invention has the advantages of special flavor and taste of oats, smooth taste, uniform milk white color, good productstability, no precipitation or stratification within one day after being poured, abundant nutrition and content of beta-glucosan being as high as 6%.
Description
technical field [0001] The invention belongs to the production field of solid beverages, in particular to a production method of oatmeal solid beverages. Background technique [0002] Oats are one of the eight major grain crops in the world's cereal crops. At present, about 17 provinces in my country grow oats. In ancient my country, oats were not only used as a food for hunger and cold resistance, but also as a medicine. It is recorded in ancient Chinese books that oatmeal can be used for lactation of puerpera, malnutrition of infants and aging and frailty of the elderly. According to traditional Chinese medicine, oats are sweet in taste and flat in nature, which can cure sweating due to sweating. In recent years, studies have found that oats have high nutritional value. It is rich in protein, unsaturated fatty acids, vitamins and minerals. The most striking thing is that oats are rich in soluble dietary fiber, and its main component is β-glucose polysaccharides. β-gluc...
