High-water textured protein processing method for wheat

Abstract

The invention discloses a high-water textured protein processing method for wheat. The method comprises the following steps: 1, chopping and mixing materials: throwing away free water on the surface of wheat wet glutens to obtain wheat wet glutens with the water content of 50-80%, pouring the wheat wet glutens to a chopping and mixing machine, adding protein powder, chopping the obtained materials until uniform mixing, and mining the obtained mixture to form a strip-shaped stuffing with the water content of 50-80%; and 2, texturing the mixture: extruding the strip-shaped stuffing at an extrusion temperature of 60-200DEG C under a screw rotating speed of 200-300r / min at an extrusion die heat temperature of 120-130DEG C under a pressure of 3.0-4.5MPa. The method allows the water required by high-water textured proteins to be balanced in a chopping and mixing mode, and raw materials are directly fed to a double screw extruder and undergo texturing treatment to obtain the high-water textured protein product; and the method effectively avoids the wheat protein vital gluten drying treatment process, reduces energy wastes and wastewater discharge, and is a green and pollution-free processing method.

Description

technical field [0001] The invention relates to a method for processing wheat high-moisture textured protein. More specifically, it relates to one kind. Background technique [0002] Wheat is the general designation of Triticum plant, is a kind of gramineous plant widely planted all over the world, originated in the Middle East. Wheat is one of the three major grains, almost all of its production is used as food, and only about one-sixth is used as feed. In 2010, wheat was the second food crop by total production in the world (651 million tons), after maize (844 million tons). Protein (commonly known as gluten) in flour, its main components are wheat protein and collagen. During the processing of wheat starch and alcohol, wheat protein is washed out to form wet gluten (more than 80% water content). At present, there are mainly several application ways of direct discharge, use as feed and processing into gluten or gluten powder. The BOD and COD of waste water with protei...

Problems solved by technology

At present, research at home and abroad mainly uses soybean protein powder, isolated protein powder, concentrated protein powder, gluten powder, pea protein powder or peanut protein powder as the main raw materials, mixed with a large amount of water and then extruded and textured, from the whole It seems that there is a process of drying and rehydrating the wet protein in the process, which causes a lot of energy waste and environmental pollution

However, wet gluten itself has problems such as high viscosity, dense texture and difficulty in mixing with other materials, and cannot directly enter the extruder.
