In the current work, vanillin-conjugated chitosan stabilized emulsions (CSVAEs) were successfully prepared and its characterization and antibacterial properties were investigated. Under stirring condition, CSVAEs were produced by a Schiff base reaction between the vanillin aldehyde group and the chitosan active amino group. The CSVAEs were described through Fourier transform infrared spectroscopy, X-ray diffraction, ultraviolet spectrophotometry and thermogravimetric analysis, which demonstrated the generation of Schiff bases between vanillin and chitosan. Furthermore, the CSVAEs displayed differences at different pH values, indicating their potential as pH-responsive materials. By studying their release behavior, pH 4 was a critical point at which the properties of the CSVAEs changed. The antibacterial tests showed that the CSVAEs had good pH-responsive antibacterial abilities against and .

In this study, the effect of chitosan-vanillin Schiff base emulsions (CSVAEs) on dough and bread characteristics was investigated. The results revealed that CSVAEs were embedded in the gluten and that the viscoelasticity and mechanical strength of the dough gradually increased with increasing CSVAEs concentration, α-helical and β-fold content, and elastic structure in the dough increased with the same patterns. The basic properties of bread were measured, and it was found that low concentrations of CSVAEs were effective in improving the quality of bread and slowing the staling rate.
