چکیده انگلیسی
A stable low-energy spontaneous trans-cinnamic acid (trans-CA) nanoemulsion with a particle size of 46.7â¯Â±â¯1â¯nm, polydispersity indice of 0.27â¯Â±â¯0.01 was formulated. Antimicrobial effects of trans-CA nanoemulsion displayed minimum inhibitory concentration (MIC) of 0.78â¯mg/mL and minimum bactericidal concentration (MBC) of 3.13â¯mg/mL for Staphylococcus aureus while Salmonella typhimurium had MIC and MBC of 1.56 and 3.13â¯mg/mL, respectively. However, Pseudomonas aeruginosa showed an MIC and MBC of 3.13 and 6.25â¯mg/mL respectively. Biofilm formation inhibition showed that the concentrations of trans-CA nanoemulsion required to inhibit â¥50% biofilm formation by S. aureus, S. typhimurium and P. aeruginosa were 0.1, 0.2 and 0.39â¯mg/mL respectively. As for biofilm eradication, the concentrations required to eradicate â¥80% biofilm formed by S. aureus, S. typhimurium and P. aeruginosa were 0.78, 6.25 and 6.25â¯mg/mL, respectively. When applied to fresh-cut lettuce, nanoemulion displayed 65% reduction of aerobic mesophilic bacteria and 61% reduction of aerobic psychrophilic bacteria. These results demonstrated that trans-CA nanoemulsion has potential to be used in preservation and extension of fresh-cut lettuce shelf-life.
