Abstract: (58 Views)
Plant antimicrobial compounds are a very suitable and safe alternative for synthetic preservatives. On the other hand, nanotechnology increases and improves the effect of the effective compounds of plants on the target cells. In this study, the antimicrobial effect (TVC and Psychrotrophic bacteria) and antioxidant effect (TBARS and PV) of edible gelatin-chitosan coating containing emulsion and nanoemulsion of Bunium persicum essential oil (1.5% and 3%) on beef meat over a 16-day period (0, 4, 8, 12 and 16) at 4 ° C was investigated. Analysis of the essential oil by GC-MS showed that the effective compounds of the essential oil are Cuminaldehyde and γ-Terpinene. The results of the antimicrobial effect of the prepared coatings showed that there is a significant difference between the control sample and the coated samples (p<0.05). Adding Bunium persicum essential oil and increasing the concentration of essential oil increased the antimicrobial activity. Also, the results of the evaluation of antimicrobial activity showed that the sample containing gelatin-chitosan coating containing 3% nanoemulsion of Bunium persicum essential oil had a higher antimicrobial effect compared to other samples. The results of peroxide index and thiobarbituric acid showed that there is a significant difference between the control sample and the coated samples (p<0.05). The addition of Bunium persicum essential oil due to its antioxidant compounds improved and increased the antioxidant activity of gelatin-chitosan coating, and the highest antioxidant activity associated with gelatin-chitosan coating containing 1.5% and 3% nanoemulsion of Bunium persicum essential oil. The results of this study showed that the gelatin-chitosan coating containing emulsion and nanoemulsion of Bunium persicum essential oil has high antimicrobial and antioxidant properties and can improve the shelf life of beef meat stored in the refrigerator. Also, this prepared coating can be used as a biodegradable packaging in the food industry.
