摘　　要：近年来,为了降低水产品腐败变质带来的经济损失,对其原因进行不断深入研究,揭示了特定腐败菌(Specific Spoilage Organism,SSOs)与水产品腐败机制密切相关。特定腐败菌是导致水产品品质下降的重要原因,群体感应(Quorum sensing,QS)调控水产品腐败过程中特定腐败菌的生长代谢及腐败特征。研究SSOs种群特征和生长代谢规律,对数字化预测水产品货架期和抑菌保鲜等具有较大的潜在价值。本文重点分析了SSOs特征和代谢物定量致腐能力指标,阐述了基于SSOs数学模型预测水产品货架期和水产品保鲜技术应用,旨在为控制腐败菌和延长水产品货架期提供基础理论参考。In recent years,in order to reduce the economic loss caused by Spoilage of aquatic products,the causes of the deterioration were studied in depth,and it has been revealed that Specific Spoilage organisms(SSOs)are closely related to the mechanism of Spoilage of aquatic products.Specific spoilage bacteria are an important reason for the decline of aquatic product quality.Quorum sensing(QS)regulates the growth,metabolism and characteristics of specific spoilage bacteria in the process of aquatic product spoilage.The study of SSOs population characteristics and growth and metabolism law has great potential value for the digital prediction of shelf life of aquatic products and antimicrobial preservation.This paper focuses on the analysis of SSOs characteristics and the index of metabolites'quantitative to corruption,and expounds the application of the prediction of shelf life of aquatic products and the preservation technology of aquatic products based on SSOs mathematical model,in order to provide a theoretical reference for the control of spoilage bacteria and the extension of shelf life of aquatic products.
