Pages

Abstract

 Objective(s): Edible films and coatings are becoming increasingly important in food preservation applications to maintain quality and extend shelf-life in perishable foods. The aim of this study was to investigate the effect of gamma irradiation at 0 and 5 KGy on in-vitro antimicrobial property of Basil seed mucilageChitosan films containing Ziziphora clinopodioides essential oil (ZEO) and MgO nanoparticles against Staphylococcus aureus, Listeria monocytogenes, Bacillus cereus, and Bacillus subtilis. Methods: The gamma irradiation doses for fabricated films were 0 and 5 kGy using a 60Co source with a dose rate of 4. 18 kGy/h at the Atomic Energy Organization of Iran (Tehran, Iran). The antimicrobial property of Basil seed mucilage-Chitosan films were evaluated using agar disk diffusion and broth micro-dilution assays. Results: The main chemical composition of ZEO were found to be carvacrol (65. 22%), thymol (19. 51%), ɣ-terpinene (4. 63%), and p-cymene (4. 86%). The highest antimicrobial activity was found for film containing ZEO 2% + MgO nanoparticles 0. 2% with inhibition zone and log DP of 5-7. 9 mm and-1. 76--3. 33, respectively. S. aureus was the most sensitive bacteria for the prepared films with inhibition zone and log DP of 5. 4-7. 9 mm and-0. 41--3. 34, respectively. A smooth, compact, and homogeneous surface without grainy and porous structure was observed in the pure films. MgO nanoparticles and ZEO completely incorporated in the film matrices. Conclusions: According to our results, it may be recommended that Basil seed mucilage-Chitosan films containing ZEO and MgO nanoparticles can be used for increasing shelf-life of stored food commodities.
