Abstract

The invention provides a preparation method of brewing powder based on a twin-screw extruder. The preparation method comprises a crushing stage, a feeding stage, a mixing stage, a vacuum feeding stage, an extrusion curing stage, a pre-drying stage, a tableting stage and a second baking stage. According to the invention, the brewing characteristics, mouthfeel and edible quality of whole grain are improved based on extrusion expansion, roller crushing, etc. of the twin-screw extruder; based on the preparation method and through corresponding process and formula adjustment, the brewing characteristics, palatability and digestibility of whole grain are enhanced; the production process provided by the invention is suitable for continuous industrial production of extruded whole grain nutrition powder; the preparation method has a high degree of automation and has effects of energy conservation and environmental protection;as a material process has relatively low moisture,the energy consumption of re-drying is relatively low, the energy utilization rate is high, and the preparation method is in line with human sustainable development strategy (the energy consumption is only 25%-40% of that of a traditional preparation method of similar products).

Description

technical field [0001] The invention relates to the field of food technology, in particular to a method for preparing reconstituted powder based on a twin-screw extruder. Background technique [0002] Whole grains are recognized as pollution-free green food, which contain natural protein fat, carbohydrates, vitamins, minerals and dietary fiber and other nutrients, which meet the reasonable ratio of human intake and have high utilization value. It contains a variety of unsaturated fatty acids, such as oleic acid, linoleic acid, linolenic acid, phospholipids, oligosaccharides, polysaccharides and flavonoids, etc., which have the functions of preventing and resisting diseases, enhancing immunity and delaying aging. effect. Although miscellaneous grains have many advantages in terms of nutrition, due to the different tastes of people in various places, it has caused certain obstacles for people to eat miscellaneous grains for a long time. How to really eat coarse grains withou...
