The short shelf life of green mussels could limit its consumption and wider distribution to the market and thus, proper storage of this product is necessary. In this study, the effects of different concentrations (1%, 2%, 3%, and 4%) of sodium lactate on the preservation of green mussels during chilled storage of nine days were determined. Changes in pH and weight loss of the mussel meat were recorded every three days. Results showed that the pH values of the treated samples are around the neutral pH (6.7 to 7.1) and are significantly higher than the untreated samples throughout the duration of storage. No significant difference was observed in the weight loss between the control and treatment groups. Thus, the results of the parameters showed that sodium lactate has the potential to be utilized as a preservative agent for meat.
