Composition of Flavour Non Volatile Compound Steamed Gourami (Osphronemus gouramy)

Abstract

This research aims to identify the composition of non-volatile flavor compounds contained in the steamed gourami (Osphronemus gouramy). The research was carried out experimentally with the treatment of steamed gourami samples (at 100℃ for ± 30 minutes). This research was conducted at the Fisheries Product Processing Laboratory, Faculty of Fisheries and Marine Sciences, Padjadjaran University, Jatinangor; IPB Integrated Laboratory. A simple product description test was carried out on samples which included the appearance of the meat, aroma, texture, and taste. Identification of non-volatile flavor compounds using tools High Performance Liquid Chromatography (HPLC). The results showed that steamed gourami has 15 identified non-volatile flavor compounds of 15 amino acid compounds. Two umami-flavored amino acids are 4.09% glutamic acid and 2.67% aspartic acid. The four sweet tasting amino acids are 1.53% alanine, 1.19% threonine, 1.13% glycine and 1.01% serine. The nine bitter amino acids are lysine 2.54%, leucine 2.11%, arginine 1.64%, valine 1.30%, isoleucine 1.29%, phenylalanine 1.14%, tyrosine 0.91%, methionine 0, 79% and histidine 0.66%. Steamed gourami has an intact appearance and is pale white in color. The aroma of steamed gourami is fresh and tasty according to the specific gourami. The texture of the meat is dense, soft and very compact. The taste of steamed gourami is savory according to the specific type.
