Problems solved by technology

[0004] Aiming at the problems existing in the prior art in the process of preparing plant tissue protein after extrusion and drying, the surface shrinkage is too hard and the toughness and elasticity are reduced. The present invention provides a wet dehydration method that maintains the flexibility of plant tissue protein. The method of cooling gradient dehydration can remove the water evenly and slowly, reduce the impact on the structure, prevent the surface from shrinking and hardening, and the obtained plant tissue protein has good elasticity and chewing properties

Abstract

The invention discloses a wet dehydration method for maintaining the flexibility of plant tissue protein. The method comprises the following steps: mixing 70-80 parts of soybean protein isolate, 20-30 parts of pea protein, 10-20 parts of glutinous rice flour and 5-10 parts of peanut protein powder into a mixed material; adding a sodium alginate and / or konjac glucomannan solution, mixing and stirring the components, adjusting the water content to be 40-50%, and standing for 18-24 hours; performing extrusion by using a twin-screw extrusion process, wherein the moisture content of the plant tissue protein after extrusion forming is 30-40%; reducing the temperature to 60-70 DEG C at the humidity of 30-40% in a gradient mode, wherein the dehydration time is 1-2 h every time until the moisture in the tissue protein is constant. The moisture is uniformly and slowly removed through a humidity and temperature reduction gradient dehydration method, so that the influence on the structure is reduced; therefore, the surface of the plant tissue protein is not shrunk and hardened, and the obtained plant tissue protein is good in elasticity and chewing performance.

Description

technical field [0001] The invention belongs to the technical field of tissue protein food processing, and in particular relates to a wet dehydration method for maintaining the flexibility of plant tissue protein. Background technique [0002] Texturized vegetable protein is a vegetable protein product with a fibrous structure and taste similar to animal muscle. It has strong water absorption and oil absorption. It is similar to the fibrous tissue of lean meat. After rehydration, it has certain elasticity, toughness and chewing properties. At the same time, it is low in fat and high in protein, and the biological value of digestion and absorption in the human body reaches 93%-97%. It has the function of preventing high blood pressure, obesity, cardiovascular and cerebrovascular diseases and other "modern civilization diseases", and can partially or completely replace animal meat. Enjoy the reputation of "vegetable meat". Textured soybean protein, also known as plant meat, i...
