Abstract
Physical properties and the microstructure of Som-fug, a Thai-style fermented fish sausage, with seven different commercial brands were determined. The released water contents of Som-fug samples ranged from 5.81 to 15.81% and expressible water contents were different among the samples tested (p<0.05). Differences in hardness, fracturability, adhesiveness, springiness, cohesiveness and resilience were also observed. L*, a*, b* and whiteness varied with the samples. Overall, the samples had different acceptability in texture and color. Microstructural study revealed that Som-fug had a three-dimensional network. A more void and open structure correlated well with greater released water and was associated with lower hardness and cohesiveness. Therefore, the different physical properties and microstructure of Som-fug could be influenced by the differences in raw materials, ingredients, processing, and fermentation characteristics, and determined the acceptability of products.
