| 摘 要： | 荷叶含有多种功能成分,具有明显的抑菌活性和抗氧化作用。将荷叶提取物配成0.3%、0.5%、0.7%和0.9%的溶液,注射于冷却猪肉中,通过测定细菌总数、TVB-N值、TBA值和双烯值的变化,来评价荷叶提取物对冷却猪肉保质期的影响。结果表明:向冷却猪肉中注射荷叶提取物,在贮藏过程中,处理样的细菌总数、TVB-N值、TBA值和双烯值均明显低于对照样。荷叶提取物的浓度越高,对细菌总数和TVB-N值的影响越明显,但对TBA值和双烯值的影响没有明显规律。可以得知,荷叶提取物可抑制猪肉中细菌的繁殖,减缓脂肪氧化,延长保质期。

| Abstract: | Lotus leaf has various functional components,obvious bacteriostasis activity and antioxidation.different concentrations of lotus leaf extracts solutions(0.3 %,0.5 %,0.7 % and 0.9 %) were added to chilled pork,total bacterial count,TVB-N value,TBA value and diene value were detected to evaluate the effects of lotus leaf extracts on shelf life of chilled pork.The results showed that total bacterial count,TVB-N value,TBA value and diene value were lower significantly than controlled group.The higher concentration of lotus leaf extracts had more significant effect on total bacterial count and TVB-N value,but not obvious effect law on TBA value and diene value.Lotus leaf extracts could inhibit bacterial reproduction,slowdown fat oxidation and prolong shelf life of chilled pork. |
