复合香辛料提取物结合真空包装抑制风干肠贮藏过程中生物胺积累及品质劣变

Inhibitory of Compound Spice Extract Combined with Vacuum Packaging on Biogenic Amines Accumulation and Quality Deterioration in Dry Sausage during Storage

本文研究了添加复合香辛料提取物(肉桂、丁香和八角)结合真空包装对哈尔滨风干肠贮藏过程中生物胺积累的抑制作用,同时考察了添加复合香辛料及真空包装对风干肠贮藏过程中理化指标、微生物指标及感官品质的影响。研究结果表明,添加复合香辛料提取物结合真空包装可有效抑制风干肠贮藏过程中生物胺(酪胺、尸胺、腐胺、组胺、2-苯乙胺和色胺)的积累,抑制pH值和挥发性盐基氮值的增加,降低脂肪的氧化程度,有效抑制风干肠贮藏过程中好氧菌数、乳酸菌数及肠杆菌数的增长。此外,真空包装可显著降低(P<0.05)风干肠贮藏过程中水分的损失,保持风干肠的感官品质;添加复合香辛料提取物可以显著提高(P<0.05)风干肠的感官品质。主成分分析表明:风干肠中生物胺的积累与总好氧菌、乳酸菌、肠杆菌、pH值、TVB-N和TBARS的变化密切相关。添加复合香辛料提取物结合真空包装可有效抑制风干肠贮藏过程中生物胺积累并抑制其品质劣变。

Inhibition of compound spice extracts(cinnamon,clove and star anise)and vacuum packaging on biogenic amines accumulation in dry sausage during storage was investigated in this study.Meanwhile,the change of physicochemical properties,microorganism,and sensory quality in dry sausage was also studied.The results showed that the addition of a compound spice extract combined with vacuum packaging effectively inhibited the accumulation of biogenic amines(tyramine,cadaverine,putrescine,histamine,2-phenylethylamine,and tryptamine)in dry sausage during storage,and reduced the increasing of pH and total volatile base nitrogen value.Compound spice extracts and vacuum packaging also decreased the oxidation of fat,and the growth of total aerobic bacteria,lactic acid bacteria,and enterobacteriaceae.In addition,vacuum packaging significantly reduced(P<0.05)the loss of moisture,and maintain the sensory quality of dry sausage,and the addition of compound spice extract significantly improved(P<0.05)the sensory quality of dry sausage.The principal component analysis showed that the accumulation of biogenic amines in the dry sausage was closely related to the changes of total aerobic bacteria,lactic acid bacteria,Enterobacteriaceae,pH,TVB-N and TBARS value.Thus,compound spice combined with vacuum packaging effectively inhibited the accumulation of biogenic amines and reduced the quality deterioration of dry sausage during storage.
