Preparation process of fiber drawing protein

Abstract

The invention relates to a preparation process of edible protein, in particular to a preparation process of fibrous protein with lean meat-like fibrous tissue structure. The technical solution of the present invention is to select first-grade large peanuts, obtain medium-denatured low-fat peanut meal after refining, crush the medium-denatured low-fat peanut meal into peanut protein powder, add water to condition and temper after selection and separation, and send it to a ripening machine to extrude Press-cured, then diced and dried. The speed of the curing machine is controlled at 130-150r / min, and the temperature is controlled at 60-140°C in 13 stages from low to high from the inlet to the outlet. By adopting the process provided by the present invention, the medium-denatured defatted peanut meal with severe protein denaturation and low nutritional value can be prepared into fiber-drawn protein with good fibrous filamentous structure, high protein, low fat, zero cholesterol, and fragrant taste, improving the The utilization value of neutral denatured defatted peanut meal.

Description

technical field [0001] The invention relates to a preparation process of edible protein, in particular to a preparation process of fibrous protein with lean meat-like fibrous tissue structure. Background technique [0002] Peanut is one of the main oil crops in my country, and its annual output ranks first in the world. At present, the traditional oil extraction methods used by most peanut enterprises in China are mechanical pressing and organic solvent leaching. The by-product defatted peanut meal after oil extraction has a protein content of more than 50%, which is an important source of plant protein. According to statistics, my country's oil processing enterprises will produce more than 3 million tons of defatted peanut meal every year. In the process of oil extraction, peanut protein will be denatured to varying degrees. At present, low-denatured defatted peanut meal can be directly used to process various high-protein foods, such as protein beverages, food additives,...

Problems solved by technology

At present, low-denatured defatted peanut meal can be directly used to process various high-protein foods, such as protein beverages, food additives, and textured protein, due to less protein denaturation, while medium- and high-denatured defatted peanut meal has serious protein denaturation and low nutritional value. Reduced value, often used as livestock feed, fertilizer or fuel, resulting in greater waste
