Microbial and chemical properties of Cambodian traditional fermented fish products.

Background: Fermented fish products, commonly consumed in south-east Asia, are used as condiments that contribute to people's nutritional sources and as seasonings to improve food taste and flavour. Among these, the Cambodian products prahok (fish paste), kapi (shrimp paste) and toeuk trey (fish sauce) have not been examined in detail. This is the first study to investigate their chemical and microbial properties.
