摘  要：
以五花肉为原料,腌制时添加不同含量(100、300、500 mg/kg的姜辣素进行风干成熟,测定样品理化指标、微生物及生物胺含量变化情况,研究姜辣素对培根风干成熟过程中微生物及生物胺形成的抑制效应。结果表明:与对照组相比,姜辣素能显著抑制菌落总数和肠杆菌(P<0.05),在风干培根样品中共检测到腐胺、尸胺、组胺、酪胺、精胺5种生物胺;生物胺总量随着风干时间的延长呈显著增加趋势(P<0.05),100、300、500 mg/kg处理组与对照组总生物胺含量存在显著性差异(P<0.05)。300 mg/kg处理组总生物胺含量最低,为94.13 mg/kg相对于对照组降低了34.56%,且此时腐胺、尸胺、酪胺、组胺和精胺含量也得到了很好的抑制,相对于对照组分别下降了26.60%、40.59%、37.08%、72.19%和23.59%。添加姜辣素能显著降低样品中挥发性盐基氮含量(P0.05对于提高培根的品质及安全性具有较好的效果。

摘  要：
Green bacon belly pieces were used to produce dry-cured bacons, and different concentrations of gingerol(100, 300, and 500 mg/kg) were added during the salting process. After curing and drying, the changes in physical and chemical indexes, microorganisms and biogenic amine content were analyzed to explore the inhibition of microorganism and biogenic amines in dry-cured bacons. The results showed that gingerol could significantly inhibit the total plate count and Enterobacteriaceae count as compared to the control group(P < 0.05). Five kinds of biogenic amines(putrescine,cadaverine, histamine, tyramine and spermine) were detected in dry-cured bacons. Total biogenic amines content increased significantly during the dry-ripening process(P < 0.05). Significant differences(P < 0.05) were observed in the treated groups as compared with the control group. The group treated with gingerol at 300 mg/kg had the lowest content of biogenic amines, which was 94.13 mg/kg and reduced by 34.56 compared with the control group. The contents of putrescine, cadaverine,tyramine, histamine and spermine were reduced by 26.60%,40.59%,37.08%,72.19% and 23.59%,respectively, compared with control group, indicating a very effective inhibition. Adding gingerol could also reduced significantly the content of volatile base nitrogen in dry-cured bacon(P < 0.05), and was effective for improving the quality and safety of bacons.
