| description | Retarding the protein deterioration of shrimp during storage is important for maintaining its quality. <i>Lactobacillus plantarum</i> SS-128 (<i>L. plantarum</i> SS-128) is a biocontrol bacterium that can effectively maintain the fresh quality of food. This research establishes a myofibril simulation system and refrigerated control system to explore the impact of <i>L. plantarum</i> SS-128 on the quality and shelf life of refrigerated shrimp (<i>Litopenaeus vannamei</i>). Through the bacterial growth assay and AI-2 signal molecule measurement, the effect of the AI-2/LuxS quorum sensing (QS) system of <i>L. plantarum</i> SS-128 and shrimp spoilage bacteria was established. In the myofibril simulation system, a study on protein degradation (dimer tyrosine content, protein solubility, sulfhydryl content, and carbonyl content) showed that adding <i>L. plantarum</i> SS-128 effectively slowed protein degradation by inhibiting the growth of food pathogens. The application to refrigerated shrimp indicated that the total volatile basic nitrogen (TVB-N) value increased more slowly in the group with added <i>L. plantarum</i> SS-128, representing better quality. The total viable count (TVC) and pH results exhibited similar trends. This study provides theoretical support for the application of <i>L. plantarum</i> SS-128 in storing aquatic products. |
