Embodiment 1

[0011] The low-temperature soybean meal and water at 50°C to 60°C are sheared and mixed at a ratio of 1:8, and the pH value is adjusted to 7±0.5, and then separated three times to remove fibrous substances, and the pH value of the liquid phase is adjusted to 4.5±0.2 , the above-mentioned feed liquid is centrifugally separated by a horizontal screw separator at a high speed, and the solid phase is crushed and then pumped into the mixing shearer, where the high mixing and shearing effect inside the shearer is used to prepare the front The tricalcium phosphate solution is mixed with the feed liquid, and then neutralized in the neutralization tank. After neutralization, it is sterilized and modified at 130°C, homogenized under high pressure at 200Mpa, and spray-dried at 240°C. After inspection, the index of the finished product is: protein content > 80%, calcium content > 3%, phosphorus content > 2%, sodium content < 1%.

Embodiment 2

[0013] Shear and mix low-temperature soybean meal with water at 50°C to 60°C at a ratio of 1:10, and adjust the pH value to 7.0±0.5, then perform three separations to remove fibrous substances, and adjust the pH value of the liquid phase to 4.5±0.2 , the above-mentioned feed liquid is centrifugally separated by a horizontal screw separator at a high speed, and the solid phase is crushed and then pumped into the mixing shearer, where the high mixing and shearing effect inside the shearer is used to prepare the front The tricalcium phosphate solution is mixed with the feed liquid, and then enters the neutralization tank for neutralization. After neutralization, it is sterilized and modified at 145°C, homogenized under high pressure at 300Mpa, and spray-dried at 280°C. The finished product is inspected and its index is: protein content > 80%, calcium content > 3%, phosphorus content > 2%, sodium content < 1%.

Abstract

The invention provides a process for extracting high-calcium high-phosphorus and low-sodium soybean protein. The process comprises the following steps of: performing shear mixing on low-temperature bean pulp and water; adjusting the pH and separating fiber substances out; performing high-speed centrifugal separation; disintegrating a solid phase, and mixing with a tricalcium phosphate solution and a feed liquid in a mixing shearer; neutralizing, sterilizing, modifying, homogenizing under high pressure and performing spray drying; and packaging a finished product and warehousing. The soybean protein extracted with the process has high protein content, high dispersity, high calcium content, high phosphorus content and low sodium content, and can be applied to multiple nutritional foods.

Description

technical field [0001] The invention relates to the technical field of soybean deep processing, in particular to a high-calcium, high-phosphorus, low-sodium soybean protein extraction process. Background technique [0002] Soybean protein is getting more and more people's favor because of its remarkable nutritional value. In some nutritious foods, manufacturers usually use soybean protein in combination with some beneficial minerals. Due to the low dispersibility and poor solubility of ordinary soybean protein, the combined use effect is not ideal. Contents of the invention [0003] Therefore, the present invention provides a high-calcium, high-phosphorus, and low-sodium soybean protein extraction process. The extracted product has good dispersibility, high protein content, high calcium and phosphorus content, and low sodium. [0004] In order to achieve the above-mentioned technical purpose, the present invention adopts the following technical scheme: a high-calcium, hig...
