The effects of vacuum package combined with 0.1% ε-polylysine and 0.2% rosemary extract (V + RP) on the quality attributes and microbial communities of large yellow croaker () during ice storage were investigated. The quality was evaluated by chemical characteristics (total volatile basic nitrogen (TVB-N), K-value and biogenic amines (BAs)), microbiological indexes (Total viable counts (TVC), bacteria counts, bacteria counts, Psychrophilic bacteria counts (PBC)), changes in microbial composition were analyzed using high-throughput sequencing. Results showed that the increase of TVB-N, K-value, microorganisms and BAs could be inhibited by V + RP. and were detected in all samples. increases rapidly in the middle of storage. and were related to the decomposition of ATP, the formation of BAs, and TVB-N, respectively. In conclusion, V + RP presented the optimal effects, which could extend the shelf life of large yellow croaker for another 9 days compared with the control.
研究了真空包装结合0.1%ε-聚赖氨酸和0.2%迷迭香提取物(V + RP)对大黄鱼在冰藏期间品质特性和微生物群落的影响。通过化学特性(总挥发性盐基氮(TVB-N)、K值和生物胺(BAs))评估品质,通过微生物指标(总活菌数(TVC)、假单胞菌属细菌计数、乳酸菌属细菌计数、嗜冷菌计数(PBC))进行评估,使用高通量测序分析微生物组成的变化。结果表明,V + RP可抑制TVB-N、K值、微生物和BAs的增加。在所有样品中均检测到假单胞菌属和乳酸菌属。在贮藏中期,假单胞菌属迅速增加。假单胞菌属和乳酸菌属分别与ATP的分解、BAs的形成和TVB-N有关。总之,V + RP呈现出最佳效果,与对照相比,可将大黄鱼的货架期延长9天。
