Description

technical field [0001] The invention relates to a food processing technology, in particular to a preparation method of freeze-dried corn flour. Background technique [0002] Corn flour is divided into dry corn flour and freeze-dried corn flour. Freeze-dried corn flour is in a vacuum state, using the principle of sublimation, so that the moisture in the pre-frozen food is directly sublimated into water vapor in the ice state without melting the ice. Remove, so that the food is dry, rich in vitamins, glutathione and other essential nutrients for the human body. Good rehydration, high nutritional value and health care effect. As a ready-to-eat solid beverage, it maintains the nutritional content of fresh corn and has an excellent taste. It is a fashionable drink with huge market potential. [0003] At present, the preparation process of dried corn flour is: corn raw material→drying→threshing→selecting→cleaning→drying→drying→crushing→packaging→obtaining the finished product; ...
