Abstract

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.

期刊介绍： The FSB journal covers food chemistry and analysis for compositional and physiological activity changes, food hygiene and toxicology, food microbiology and biotechnology, and food engineering involved in during and after food processing through physical, chemical, and biological ways. Consumer perception and sensory evaluation on processed foods are accepted only when they are relevant to the laboratory research work. As a general rule, manuscripts dealing with analysis and efficacy of extracts from natural resources prior to the processing or without any related food processing may not be considered within the scope of the journal. The FSB journal does not deal with only local interest and a lack of significant scientific merit. The main scope of our journal is seeking for human health and wellness through constructive works and new findings in food science and biotechnology field.
