Antimicrobial packaging is an innovative active packaging, especially for meat and meat products. The present study has been carried out with the objective of prolonging the shelf life of chicken meat by using gelatin-chitosan (GC) film containing different concentrations of Cinnamon zeylanicum essential oil (CZEO) (0, 0.3, 0.6, and 0.9% v/v) at the refrigerated condition for 12 days. The obtained results indicated that the microbial count of samples wrapped with the films incorporated with the CZEO was significantly lower than control and remained below the acceptable limit of meat (7 log CFU/g). The total volatile base nitrogen (TVB-N) was 7.11 mg/100 g and after 6 days reached 30.18 mg/100 g in control, whereas it was lower than 25 mg/100 g for samples wrapped with GC films containing 0.6% and 0.9% CZEO. Compared with the control sample, the levels of peroxide value (POV) of the wrapped samples with GC films incorporated CZEO at 0.3%, 0.6 and 0.9% were decreased by 2.07, 3.23, and 3.4 meq peroxide oxygen/1000 g lipid, respectively, at the end of storage time. As a result, the integration of CZEO into GC film can extend the shelf life of the chicken meat in refrigerated conditions for at least 12 days without any unfavorable organoleptic properties

Biodegradable active packaging containing essential oils with antimicrobial properties is one alternative strategy that can be considered by the food packing industry to reduce the use of environmentally harmful synthetic polymers. Chitosan is a safe, natural, no allergen, and biocompatible polymer with health benefits. This study was conducted to investigate the effects of chitosan coating contain Ajwain essential oil (AEO) on the shelf-life of chicken breast meat during refrigerated storage. AEO was extracted and its composition was analyzed by GC/MS, the AEO was added to chitosan solution in different concentrations (0, 0.5%, and 1% (v/v)) and chicken breast meat was coated by chitosan solution, The microbiological properties of chicken breast meats, such Total aerobic mesophilic bacteria (AMB), Enterobacteriaceae, total aerobic psychrotrophic bacteria (APB), and Pseudomonas spp. were determined during 13 days of storage. The results showed that using of AEO has significant effects on the reduction of all followed groups of microorganisms compared with the control group. In the present study, 1% v/v AEO treatment was the most effective in microbial groups throughout the storage period. This study showed that chitosan coating contains 1% AEO have good antimicrobial activity and can be used to extend the shelf-life of the meat products.
