摘要:

通过将多甲氧基黄酮提取物(PMFs)对鲜猪肉进行涂膜处理,并采用PE 有氧包装形式,以色价、pH 值、挥发性盐基氮值(TVB-N 值)、细菌总数和假单胞菌数的变化为指标,评价PMFs 对冷却肉的保鲜效果。结果表明,PMFs 对冷却肉具有一定的保鲜效果,与乙醇对照组相比,经PMFs 处理后的冷却肉其pH 值、TVB-N 值、细菌总数和假单胞菌数等指标均变化缓慢,且对肉色无不良影响,可使冷却肉保质期延长至8d。

关键词: 多甲氧基黄酮, 冷却肉, 涂膜保鲜, 细菌总数

Abstract:

The preservation effect on chilled meat coated with polymethoxyl flavonoid extract (PMF) was studied. The color, pH, TVB-N, total bacteria counts and Pseudomonas amount of chilled meat was used to evaluate its preservation effect. Results indicated that chilled meat coated with PMF exhibited an obvious fresh-keeping effect and the chilled meat treated by PMF exhibited an attenuated alteration of pH, TVB-N, total bacteria counts and Pseudomonas amount. Moreover, PMF had no effect on color of chilled meat. The shelf life of chilled meat treated with PMF was extended to 8 days.

Key words: polymethoxyl flavonoid, chilled meat, coating preservation, total bacteria counts
