摘要: Calcium-fortified soy protein emulsions stabilized by sodium tripolyphosphate are of considerable importance for the development of calcium-fortified soymilk products. This study aimed to investigate the characteristics and stabilities of calcium-fortified soy protein emulsions stabilized by sodium tripolyphosphate. When the concentration of sodium tripolyphosphate ranged from 0 to 0.6%, the emulsion potential and emulsification activity index gradually increased to 35.5 mV and 71.7 +/- 0.8%, while the particle size and flocculation index progressively decreased to 756.2 +/- 41.3 nm and 16.21%, respectively. However, when the concentration exceeded 0.6%, these characterization data plateaued. Microstructural analysis revealed a uniform distribution of droplets. Raman spectroscopy showed an increase in the ordered structure of proteins in the emulsion. Additionally, the centrifugal, thermal, and storage stabilities of the emulsion were enhanced. These findings offer insights into the properties of calcium-fortified soy protein emulsions stabilized by sodium tripolyphosphate and may contribute to expanding their utilization in emulsions and soy products.
