Effects of natural preservatives on quality and shelf-life of fresh pork were investigated by evaluating changes in physicochemical properties, sensory evaluation, and mcrobial properties during storage. Acidity and VBN values of pork with preservatives were lower than those of control. Total bacterial count of pork with preservatives was significantly lower than that of control during storage. Sensory results showed pork with preservatives had lower sensory color and off-flavor scores than control. Changes in pH, VBN, total bacterial count, coliform group, and sensory evaluation revealed pork with preservatives showed less quality changes than control during storage, regardless of storage temperature. Results indicated that addition of preservatives to pork increased shelf-life by 7 days at $4^{\circ}C$.
