摘要: 针对目前冷鲜肉制品保质期短、品质不稳定、易腐败变质等状况,考察了不同浓度普洱茶提取物(PETs)对冷却猪肉糜货架期的影响.结果表明,冷却猪肉糜中添加0.02%~0.12%的PETs后,在贮藏期间不仅可以有效抑制肠道菌群、假单胞菌和菌落总数的增殖,还可降低挥发性盐基氮和硫代巴比妥酸值的累积,增加红度值并保持猪肉糜良好的感官性状.Abstract: In view of the problems of cold minced meat existing in the short shelf-life such as inconsistent quality and easiness to spoilage, the effects of different concentration of Pu'er tea extracts(PETs) on the shelf-life of minced pork were studied. The results showed that the addition of PETs(0.02%~0.12%) to the samples could not only significantly inhibit the growth of Enterobactteriaceae, Pseudomonas and the total aerobic bacterial, decrease the accumulation of the total volatile nitrogen base and thiobarbituric acid-reactive substances, but also increase the minced pork a* value and keep it's good sensory properties.
