  • The antibacterial effect of tea saponin on Bacillus subtilis sp., Salmonella sp., Listeria sp., Escherichia coli sp., Pseudomonas fluorescens sp., Staphylococcus aureus sp. and Pseudomonas aeruginosa sp. was studied. The best bacteriostatic effect of tea saponin was on Salmonella sp which was used for test to observe the antibacterial mechanism of tea saponin against Salmonella sp in growth, morphology, extracellular protein, alkaline phosphatase and K+ leakage. The number of colonies of Salmonella sp., pH and water retention rate were used as indexes to evaluate the preservation of chicken breast meat by using tea saponin. The results showed that tea saponin mainly changed the permeability of cell membrane and cell wall and destroyed its barrier by destroying the normal morphology of the cells, which led to leakage of alkaline phosphatase and cell contents such as K+, protein to achieve its antibacterial function. Tea saponin inhibited the growth and reproduction of Salmonella sp. in chicken breast, slowed down the rate of pH rise, and delayed the decline of water retention rate, which indicates that tea saponin can be used as a natural bacteriostatic agent for chicken breast preservation.

The number of colonies of Salmonella sp., pH and water retention rate were used as indexes to evaluate the preservation of chicken breast meat by using tea saponin. The results showed that tea saponin mainly changed the permeability of cell membrane and cell wall and destroyed its barrier by destroying the normal morphology of the cells, which led to leakage of alkaline phosphatase and cell contents such as K+, protein to achieve its antibacterial function. Tea saponin inhibited the growth and reproduction of Salmonella sp. in chicken breast, slowed down the rate of pH rise, and delayed the decline of water retention rate, which indicates that tea saponin can be used as a natural bacteriostatic agent for chicken breast preservation.
