Embodiment 1

[0016] A soybean peptide dry powder with good solubility, the preparation method of which is as follows:

[0017] (1) Processes such as dissolving soybean protein isolate raw materials, enzymatic hydrolysis, separation and refining, etc., and enzymatic hydrolysis to make soybean peptide solution;

[0018] (2) Transport the soybean peptide solution to the spray tower for spray drying. The air inlet temperature of the spray tower is 140°C, the air outlet temperature is 120°C, and the pressure inside the spray tower is -50Pa. Flow to the top of the tower, and then combine with the undried liquid at the top of the tower, and then continue to spray dry to obtain granular materials;

[0019] (3) The spray-dried granular material will continue to be drum-dried in the drum drying device in the spray tower. The temperature of the drum drying in the tower is 70 ° C, and the time is 35 minutes, and the hot air vortex is passed during the drying process The granulation is carried out in ...

Abstract

The invention relates to the technical field of soybean peptide products, in particular to a preparation method of high-soluble soybean peptide dry powder. The preparation method of the high-soluble soybean peptide dry powder includes: enzymatically hydrolyzing soybean protein isolate to obtain soybean peptide solution, and drying and granulating the soybean peptide solution to obtain soybean peptide dry powder; drying includes spray drying and then roller drying, and granulating includes granulating via hot blast eddy circulation during roller drying. The soybean peptide dry powder has good solubility and dispersity in water and is free of clustering or knotting, and an obtained solution is uniform, tender and clear. The preparation method provided herein enables low and stable water content for the soybean peptide dry powder through repeated drying and granulating and also enables good solubility and dispersity for the soybean peptide dry powder, obtained particulate powdered soybean peptide is large in particle size, dusts rarely and is more convenient and safer to use and easy to control.

Description

technical field [0001] The invention relates to the technical field of soybean peptide products, in particular to a preparation method of soybean peptide dry powder with good solubility. Background technique [0002] Compared with soybean protein and amino acids, soybean peptides are easier to absorb and absorb faster. Now it has been paid attention to by many insightful people who pay attention to health products, and people make more use of the high-quality performance of soybean peptide powder to supplement the protein that the human body lacks. However, the quality of soybean peptide powder currently available on the market is uneven, mixed with good and bad people, the product quality is very unstable, and the product is particularly dusty, and it is very easy to agglomerate when it is dissolved in water, which brings great problems to producers and processors. the inconvenience. How to provide a soybean peptide product with good solubility and good dispersibility has...
