Abstract
Effect of inoculation of different lactic acid bacteria (LAB) on the fermentation and quality of Som-fug from bigeye snapper was
investigated. Som-fug inoculated with Pediococcus acidilactici at 104 CFU/g (PA104) had a greater acceptability than those inoculated
with Lactobacillus plantarum and Pediococcus pentosaceus at either 104 or 106 CFU/g and the control (without inoculum). During
fermentation, PA104 exhibited a higher rate of fermentation than the control as indicated by the greater rate of pH drop and lactic acid
production (po0.05). Based on pH desired (pH 4.5), the fermentation was completed within 48 and 36 h for the control and PA104,
respectively. Due to higher acid production rate, the textural development of PA104 was more pronounced. Som-fug inoculated with
LAB generally exhibited higher hardness and adhesiveness than the control (po0.05), when assessed by texture profile analysis (TPA).
From the result, inoculation with P. acidilactici resulted in a reduction of fermentation time and improved the quality of Som-fug.
Therefore, P. acidilactici can be used as a potential starter for Som-fug fermentation.
