Effect of carboxymethyl cellulose-based active packaging incorporated with Ziziphora clinopodioides extract on the shelf life of chicken fillet

The use of biodegradable polymers, especially in the form of active packaging, has shown promising results in maintaining chicken meat quality and extending its shelf life. This study aimed to evaluate the effect of active packaging based on carboxymethyl cellulose (CMC) and Ziziphora clinopodioides extract on the shelf life of chicken fillets during a ۱۲-day refrigerated storage. A complete randomized block design was implemented with five treatments, including uncoated chicken fillets (control), and fillets coated with Z. clinopodioides extract at ۰.۷۵% and ۱.۵%, either alone or in combination with CMC as active packaging. The results showed that Z. clinopodioides extract significantly prevented microbial spoilage and oxidative deterioration of the fillets in a concentration-dependent manner. The use of CMC facilitated the slow and continuous release of the extract to the fillets, maintaining the effectiveness of the extracts. Fillets with active packaging containing ۱.۵% extract had the lowest mean (p < ۰.۰۵) counts of mesophilic bacteria and psychrophilic bacteria (۵.۰۰ and ۳.۹۰ log CFU/g, respectively), total volatile basic nitrogen (۱۶.۴۵ mg/۱۰۰g), peroxide value (۲.۹۵ meq/kg), and thiobarbituric acid index (۰.۶۵ mg MDA/kg), while exhibiting the highest water-holding capacity (۵۳.۱۵%). In conclusion, it was determined that active biodegradable packaging based on CMC containing ۱.۵% Z. clinopodioides extract effectively preserved the quality and extended the shelf life of chicken fillets for at least six days at refrigerator temperature.
