pH is a factor that determine organism species dominated in the fermentation. Result of pH of fish paste with
different fermentation time is displayed in Table 1. Longer fermentation time would increase pH of the product. The
early step of fish paste processing, pH of product was approximately 6. During the fermentation process, pH would
increased to 6.5 and in the end of the process pH would decline to 4.5 (14). But when the fermentation proceeds,
there would be increased in pH due to the formation of ammonia. The research result of (15), reported that Chinese
traditional low salt fermented whole fish product had a high acidifying activities and were able to reduce the pH to
lower than 4.5.
