Problems solved by technology

But its price is high, and the soybean protein produced by it has a certain beany smell and poor flavor
At the same time, the unit energy consumption in the production process of low-temperature defatted soybean meal is too high, which is not conducive to saving production costs

Abstract

The invention discloses a method for extracting a soybean protein concentrate through high-temperature low-denaturing soybean meal, and belongs to the field of food processing. The problems of high cost, high energy consumption, low daily production capacity, low protein purity and poor nitrogen dissolving index existing in the production of the soybean protein concentrate in the prior art can be solved. According to the method disclosed by the invention, low-denaturing soybean meal produced by a high-temperature soybean meal production line is used as a raw material, and the production method comprises a production technology of producing the low-denaturing soybean meal through the high-temperature soybean meal production line, and an extraction technology of the soybean protein concentrate. The method disclosed by the invention is suitable for production of the soybean protein concentrate.

Description

technical field [0001] The invention relates to a method for extracting concentrated soybean protein by using high-temperature and low-denatured soybean meal, which belongs to the field of food processing. Background technique [0002] Soybean protein concentrate is made from soybeans, and after crushing, peeling, extraction, separation, washing, drying and other processing techniques, the oil and low molecular weight soluble non-protein components (mainly soluble sugar, ash, alcohol) in soybeans are removed. After dissolving protein and various odor substances, etc.), the obtained soybean protein product contains more than 65% (dry basis) protein (N×6.25). [0003] At present, there are three main production methods of soybean protein concentrate: ethanol extraction method, dilute acid extraction method and wet heat extraction method. The dilute acid extraction method requires a large amount of acid and alkali, and discharges a large amount of sugary and nutritious wastewa...
