Abstract: A Pickering particle dry powder and a preparation method are used in food processing. The preparation method includes stirring peanut protein isolate and water as raw materials to obtain peanut protein isolate dispersion, subjecting the peanut protein isolate dispersion to ultrasonic treatment, subjecting the resultant to cross-linking reaction with transglutaminase to obtain a monolithic geld, shearing and homogenizing the monolithic gel to obtain a microgel particle dispersion, spray drying the microgel particle dispersion to obtain the Pickering particle dry powder. The Pickering particle dry powder prepared by the ultrasonic-assisted enzyme method is still in nanometer level after rehydration, which is beneficial to preparing Pickering emulsion with strong stability. The preparation method has the advantages of simple operation and low cost, which is beneficial to actual production in the food industry.

Abstract: A plant protein-based whole-cut fried chicken nugget is prepared from raw materials including peanut protein, wheat protein, seasonings, water-retaining agent, and coating flour in proportions measured in parts by weight. The preparation method of the plant protein-based whole-cut fried chicken nugget includes mixing the raw materials uniformly according to the proportions, subjecting to high-moisture extrusion treatment, boiling the resulted extrudate with water for an appropriate period, then coating with flour, placing in a frying pan at an appropriate temperature, and frying for an appropriate period. The plant protein-based whole-cut fried chicken nugget has a golden surface, a strong aroma, a crispy outside and tender inside, good elasticity and chewiness, no beany taste, high protein content, and rich nutrition.

Abstract: A peanut protein vegetarian sausage and a preparation method thereof are described. The peanut protein vegetarian sausage is prepared from components including low-temperature defatted peanut protein powder, soybean protein isolate, vital wheat gluten, and modifier. The vegetarian sausage has a protein content of 60% or more, zero cholesterol and low fat, and has the characteristics of good taste, being rich in nutrients and convenience to eat. Also described are a preparation method of the vegetarian sausage, which includes mixing the main materials, performing an extrusion treatment, adding water and an auxiliary material online during the extrusion, and cooling the product obtained after extrusion molding to give the peanut protein vegetarian sausage. The preparation method is a pure physical processing method with a high degree of automation, and the processing is free from any pollutant discharge.

Abstract: High-moisture TPP and its preparation by crushing and mixing low-temperature defatted peanut protein powder and extrusion texturizing at 60° C. to 80° C. in the feeding zone, 90° C. to 100° C. in the mixing zone, 120° C. to 160° C. in the melting zone, 90° C. to 150° C. at the cooling die, and 50° C. to 100° C. in the molding zone. Water is added online during extrusion to adjust the moisture content to 45% to 60%. The cooled product is high-moisture TPP that has a moisture content of 55% or more, bright white color, fragrant taste, abundant fibrous structure, is immediately edible, and can be used as a substitute for meat in the manufacture of chicken dices, pulled meat, vegetarian sausage and the like. The method fully utilizes raw materials, has almost no waste, is continuous, has a high process integration, and low energy consumption, and it can enhance the value of peanut protein powder.

Abstract: A method for improving the quality of high-moisture texturized peanut protein (TPP) by TG enzyme is provided. The method includes crushing low-temperature defatted peanut protein powder and mixing it with the TG enzyme, performing an extrusion texturization treatment, and obtaining the product after extrusion molding is cooled to yield the high-moisture TPP. The high-moisture TPP produced by the method has bright white color, fragrant taste, smooth surface, abundant fibrous structure and high fiber strength, and it can be used as a substitute for high-grade meat in the manufacturing of vegetarian beef and the like. The method significantly increases the degree of fibrosis of the high-moisture TPP, enhances the fiber strength, and broadens its application channels.
