The aim of this study was to determine the biogenic amines (BAs) formed in chicken breast meat packaged using different techniques (AP, Hi-O-MAP or VP) during the storage under different conditions (cold room or display case), to correlate the microbiological quality (TPC, LAB, Pseudomonas spp. and Enterobacteriaceae) of chicken meat with BAs formation and to assess the suitability of selected biogenic amines as indicators of chicken meat spoilage. The initial TPC of chicken fillets was 2.57-3.04 log cfu/g. Over time a systematic significant (p ≤ 0.05) increase in TPC was observed to >7.5 log cfu/g (AP and VP; display case) determined on day 9. It was found that cadaverine and tyramine dominated in quantitative terms in chicken fillets, regardless of packaging technique and storage conditions (166.00 mg/kg in AP meat in cold room on day 9 and 175.03 mg/kg on day 9 in MAP meat in display case, respectively). Taking into account the BAI, high and significant (p ≤ 0.05) correlation coefficients (from 0.51 to 0.95) were obtained with all analyzed indicators of microbiological quality. The concentration of cadaverine, putrescine contents or BAI can potentially serve as chemical quality indicator for freshness of chicken meat.
本研究旨在确定使用不同包装技术(AP、Hi-O-MAP 或 VP)在不同条件(冷藏室或展示柜)下包装的鸡胸肉中形成的生物胺(BAs),将鸡肉的微生物质量(TPC、LAB、假单胞菌和肠杆菌科)与 BAs 形成相关联,并评估所选生物胺作为鸡肉腐败指标的适宜性。鸡肉片的初始 TPC 为 2.57-3.04 log cfu/g。随着时间的推移,在第 9 天,无论是在冷藏还是展示柜中,TPC 都会系统地显著增加(p≤0.05)至>7.5 log cfu/g(AP 和 VP)。结果发现,尸胺和酪胺无论包装技术和储存条件如何,在鸡胸肉中都占据了数量上的主导地位(第 9 天冷藏室中 AP 肉中的含量为 166.00 mg/kg,第 9 天展示柜中 MAP 肉中的含量为 175.03 mg/kg)。考虑到生物胺指数(BAI),与所有分析的微生物质量指标都获得了高且显著(p≤0.05)的相关系数(从 0.51 到 0.95)。尸胺、腐胺含量或 BAI 的浓度可能可以作为鸡肉新鲜度的化学质量指标。
