摘　要：分别将生鲜猪肉用浓度0.1%、0.5%、1.0%与3.0%的菟丝子多糖水溶液浸渍处理，在贮藏的第1、3、6、9与12 d分别对生鲜猪肉的挥发性盐基氮、pH值、感官质量、质构、硫代巴比妥酸值、色差值及菌落总数进行测定和综合评价.菟丝子多糖能抑制生鲜猪肉的挥发性盐基氮、硫代巴比妥酸反应物的产生，脂肪的氧化，pH值的增加以及微生物的繁殖，且能改善生鲜肉的感官质量.通过综合评价，质量浓度为1.0%的菟丝子多糖对生鲜猪肉的保鲜效果最好.

Abstract：Fresh pork was soaked with a concentration of 0.1%,0.5%,0.0%,1.0%,3.0% dodder polysaccharide solution,respectively,and the volatile salt-based nitrogen,pH,sensory quality,plasma,thiobarbituric acid reactant values and total number of colonies were determined and comprehensively evaluated on the first,third,sixth,ninth and twelfth day of storage.Dodder polysaccharide can inhibit the production of volatile salt-based nitrogen,thiobarbituric acid reactants,fat oxidation,the increase in pH value and microbial reproduction of fresh pork,and can improve the sensory quality of raw fresh meat.Through comprehensive evaluation,dodder polysaccharide with a quality concentration of 1.0% has the best preservation effect on fresh pork.
