The application of processing techniques that preserve the nutritional value, quality, and bioactive properties of fermented soymilk without compromising their integrity is of great significance. Ultrasound can promote the decomposition of proteins in soymilk by disrupting their structure, and also has a cell wall-breaking effect on the fermentation strains in soymilk, causing the beneficial components of the bacteria to be released into the soymilk, thereby changing the characteristics and material composition of the fermented soymilk and increasing the content of nutrients and the stability of the soymilk. This study revealed that ultrasonic treatment (150 W, 20 min) significantly improved the texture and stability of <em>Lactobacillus gasseri</em> JM1- fermented soymilk, reduced the viscosity of the fermented soymilk (1918.80 ± 112.33 cP), and increased the water-holding capacity of the soymilk (97.12%). Moreover, ultrasonic treatment (150 W, 20 min) also led to an increase in active aglycone isoflavones such as daidzein (17.32 μg/ml) and genistein (24.48 μg/ml) in the fermented soymilk. Metabolomics and proteomics were used to establish a metabolic network of metabolites, revealing the changes in the main metabolic substances in the fermented soymilk before and after ultrasonic treatment.

To overcome these drawbacks, ultrasound-assisted enzymatic extraction (UAEE) has been proposed as an alternative synergistic approach to improve biomass disruption. In this study, the effect of ultrasound on the susceptibility of pectic substrates to enzymatic degradation was evaluated using both purified pectin and pectin-rich complex matrices (grapefruit peels and apple pomace).

Similar degradation of the cell microstructure was observed in the case of ultrasonic post treatment, although without improved hydrolysis of cell-wall pectin. This implies that prior enzymatic action weakened the matrix, making it more fragile.
