Effect and Mechanism of Freezing on the Quality and Structure of Soymilk Gel Induced by Different Salt Ions.

The quality of frozen soymilk gel is influenced by the rate of gel formation induced by salt ions . After freezing, soymilk gel with faster gelation rates exhibited a greater tendency for the transformation of protein-water interactions into protein-protein interactions. They showed a higher degree of disulfide bond formation, resulting in a more tightly knit and firm frozen gel network structure with denser and more uniformly distributed pores.
