Physical, mechanical, and antimicrobial properties of chitosan films with microemulsions of cinnamon bark oil and soybean oil

Antimicrobial films prepared with essential oil emulsions often have a high degree of opacity. This may be prevented using transparent microemulsions. The objective of this study was to characterize physical, mechanical, and antimicrobial properties of films prepared from mixtures with 1% w/w chitosan solution and microemulsions containing 1:0, 2:1, and 4:1 mass ratios of cinnamon bark oil (CBO) (1, 2 and 3% w/w) and soybean oil.
