| Summary: | The aim of this study was to develop an innovative edible coating with antioxidant and antibacterial functions, utilizing Plantago lanceolata mucilage (PLM) and postbiotics (cell-free supernatant, CFS) derived from Lacticaseibacillus rhamnosus CWKu-12. The study also aimed to evaluate the impact of this newly formulated polymer coating on various aspects of lamb over 9 days of refrigeration, including its microbial growth, physicochemical properties, lipid oxidation, and consumer acceptance. The experiments were performed using a completely randomized design with a factorial arrangement. As the storage time increased from 1 to 9 days, total viable count, and psychrotrophic count of the samples increased (p < 0.05). However, the coated samples had significantly lower microbial counts than those in the control (p < 0.05). When compared to the uncoated control, the lamb slices treated with the PLM+2 %CFS coating demonstrated a substantial reduction in, pH value (6.05 vs. 5.68), thiobarbituric acid value (0.68 vs. 0.20 mg MDA/kg), and peroxide value (5.66 vs. 2.51 meq oxygen/kg), and. Additionally, these slices exhibited increased hardness (68.45 N vs. 63.72 N), moisture content (69.73 % vs. 64.73 %), and overall acceptance (37.50 %). The findings of this research indicate that the edible coating based on PLM+CFS effectively extends the shelf-life of lamb. Future research could explore the scalability and practical applications of CFS-loaded PLM in various food systems, assessing its effectiveness across different types of meat and perishables. Overall, this novel edible coating represents a promising advancement in food storage technology, emphasizing both quality enhancement and food safety. |
