Abstract :

Rosa canina fruit extract with its high content of bioactive compounds such as vitamin C, carotenoids and polyphenolic compounds, can be used as a natural preservative in meat products. The aim of this study was to investigate the antimicrobial and antioxidant activity of Rosa canina fruit extract to improve durability at refrigerator temperature. For this purpose, ethanolic extract of Rosa canina fruit was prepared by microwave at three concentration levels (0.5%, 1% and 2%) and added to chicken samples. An extract-free sample was considered as a control. All specimens were kept at 4 °C for 10 days. Microbial properties including: Total bacterial count, Escherichia coli, Staphylococcus coagulase positive and Salmonella, physicochemical properties including: fat oxidation, free radical inhibition, methemoglobin absorption, pH and volatile nitrogen during the first, fourth, seventh and tenth days were tested. The results showed that Rosa canina Fruit extract significantly reduced the mean (P
