In the traditional sausage,fresh pumpkin was added. Based on the results of sensory test and physical and chemical indexes determination, the optimum recipe for pumpkin sausage was determined. [Result] The optimum recipe for pumpkin sausage was as follows： 100% of pork（fat to lean ratio of 2∶8）, 45% of pumpkin particles, 6% of soy protein, 7% of sugar, 3.5% of salt, 1% of spice and 0.5% of monascus red pigment. [Conclusion]The successful preparation of pumpkin sausage will provide consumers with nutrition, health and snack meat product with comprehensive nutrition and unique flavor.展开更多
