Amino Acid Profile and Volatile Compounds of Several Commercial Fish Sauces in Viet Nam
Keywords
Amino acids, commercial fish sauce, fish sauce, volatile compounds
Abstract
Profile of amino acid and volatile compounds of four commercial fish sauces in Viet Nam were investigated. Four fish sauces included Nha Trang (NTFS), 584 (584FS), Khai Hoan (KHFS) and Chinsu (CSFS). Results showed that all of fish sauces contained essential amino acids with a range from 1.14 to 3.69 mg/g. Based on essential amino acid contents, four fish sauces can be ranked in the following descending order: 584FS > NTFS > KHFS > CSFS. A total of 56 volatile compounds were detected in four fish sauces investigated and their amount in CSFS, 584FS, KHFS and NTFS was 22, 22, 19 and 16, respectively. Generally, amino acid content and amino acid profile as well as volatile compounds in these fish sauces are very complicated and they vary depending on fish sauce type.
