Abstract

The invention provides a method for preparing dried tofu based on a twin-screw extruder. The method comprises a pulverizing stage, a material feeding stage, a mixing stage, a vacuum charging stage, anextruding and aging stage, a cooling stage and a sterilizing stage. Based on the twin-screw extruder, the methods of expanding by extruding, pulverizing by a press roll and the like improve the blending property, mouthfeel and eating quality of isolated protein. According to the preparation method provided by the invention, by application of corresponding processes and formula adjustment, the blending property, palatability and digestibility of the isolated protein are improved. A production process provided by the invention is applicable to continuous industrial production of whole grain nutritional dried tofu by extruding and has high degree of automation, energy saving and environmental protection, the moisture content of materials in the process is relatively low, the energy consumption for re-drying is reduced, the energy utilization rate is high and the production process conforms to the human sustainable development strategy (the energy consumption of like products is only 25-40% of a traditional method).

Description

technical field [0001] The invention relates to the field of food technology, in particular to a method for preparing dried tofu 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 without changing...
