摘　　要：采用水提取法提取桥头地瓜中的硒多糖,研究了0.5%Vc和0.5%硒多糖对延长托盘包装冷却猪肉货架期的效果。通过测定菌落总数、pH值、TBARS值、TVB-N值及色差值5个指标,结果表明:0.5%的硒多糖处理冷却猪肉可以较好保持冷却肉在贮藏过程中的品质,对延长托盘包装的冷却猪肉货架期有明显效果。This paper explores the effects of 0.5%Vc and 0.5% selenium polysaccharide on prolonging the shelf life of cooled pork in tray packaging through the experiment on selenium polysaccharide extracted from Qiaotou sweet potato using water extraction method. By measuring the total number of colonies, pH value, TBARS value, TVB-N value and color difference value, the results show that 0.5% selenium polysaccharide treatment of chilled pork could maintain the quality of chilled pork during storage, and has obvious effect on prolonging the shelf life of chilled pork packaged in trays.
