Abstract

Latilactobacillus curvatus has a strong carbohydrate fermentative ability and antibacterial ability. It is considered as a promising probiotic by its excellent fermentation attributes and health advantages. Pickled shrimp derived from the fermentation process is highly appreciated by its unique texture, taste and flavor. However, this product is easily decomposed by spoilage bacteria especially Staphylococcus. This research evaluated the inoculation of L. curvatus (0.1-0.5 %) and different fermentation temperatures (28-30 oC) on the reduction of Staphylococcus aureus, pH and overall acceptance of the pickled shrimp after 6 weeks of fermentation. Results showed that the fermentation process should be conducted at 29 oC with 0.3 % Latilactobacillus curvatus (at initial density 9 log cfu/ml) to reduce pH to 3.70, completely against Staphylococcus aureus, obtain the highest sensory score (8.91).
