Ikan pekasam is a fermented fish product produced in Malaysia and is usually made from freshwater fish
with ground roasted uncooked rice as the main source of carbohydrate. In this study, the amino acid,
biogenic amine, and trans- and cis-urocanic acid (UCA) contents of fifteen commercial samples of Ikan
pekasam made from Javanese carp and black tilapia, that had undergone either natural or acid-assisted
fermentation, were quantified.
