Investigating the effect of Quince seed mucilage film reinforced with carboxymethyl cellulose containing ginger essential oil on the microbial, physicochemical and sensory characteristics of turkey meat

Prevention of spoilage of food products, especially types sensitive to spoilage such as poultry meat, has always been a big challenge in the food industry. Therefore, the purpose of this study imed to investigate the effect of castor bean mucilage film reinforced with carboxymethyl cellulose containing ginger essential oil (GEO) on the characteristics of turkey meat. GEO was prepared and its chemical composition was checked by gas chromatography (GC/MS). samples include; Control (C), Quince seed mucilage film reinforced with carboxymethyl cellulose (film), film containing ۱% essential oil (film+۱% GEO) and film containing ۲% essential oil (film+۲% GEO). Then microbial properties (aerobic, psychrotrophic, lactic acid and Enterobacteriaceae bacteria), chemical properties (pH, PV, TVB-N and TBARS) and sensory evaluation were done. Also, the physical properties of the films (tensile strength (TS), water vapor transmission rate (WVTR), elongation at break (EAB), humidity, swelling, thickness and transparency) were investigated. According to the results, Zingiberene (۱۵.۷۱%), α-Curcumene (۱۱.۳۹%) and β-Sesquiphellandrene (۱۰.۶۹%) were the main compounds of GEO. Film+۲% GEO treatment acted as the most effective treatment in all microbial properties and showed a significant difference with other treatments, especially the control group (P<۰.۰۵). The results indicated the improvement of physical and chemical characteristics in the samples with film, especially film+۲% GEO compared to the control group. For example, the amount of TVB-N increased from ۱۰.۶۷ mg/۱۰۰g on day ۰ to ۲۱.۶۱ mg/۱۰۰g on the final day, while this amount for the control treatment on day ۰ and ۱۲ was ۱۰.۶۸ mg/۱۰۰g and ۱۰.۰ mg/۱۰۰g, respectively. It was ۳۹.۹۵%. The sensory evaluation found that the use of film has improved the sensory characteristics of the samples in all parameters except appearance. In general, the results showed that the use of Quince seed mucilage film reinforced with carboxymethyl cellulose, especially when it contains essential oil, can be considered a factor in maintaining and improving the quality of food, especially types of meat.
