Abstract:To develop a composite preservative for soy sauce-marinated meat, formulations consisting of natural plant preservatives, allicin, tea polyphenol and ginger extract were optimized using response surface methodology. The response variables were sensory score, volatile base nitrogen (TVB-N) content and the total number of bacterial colonies of soy saucemarinated meat after storage for 9 days at room temperature (20–25 ℃). The optimal combination obtained were allicin 1.48 g/100 mL, tea polyphenols 3.14 g/100 mL and ginger extract 40.04%. It was more effective in preserving the quality of soy sauce-marinated meat than each component alone.
