Gourami (Osphronemus goramy) could be considered as an alternative low-cost ingredient due to the protein content 19% and can grow fast rate (3 months). The Gurami meat characteristics is prone to microbe’s contamination with fishy smell.
Therefore, the meat need to be processed. This research aimed to develop the production method of fish jerky, to increase the consumption of fish intake, to be model of non-mammal jerky. The optimum production process was investigated through thickness 0.5, 1.0, 1.5 cm, different oven times (40, 60, 80, 100, 120 minutes), oven temperatures (200oC and 150oC) and frying time (20, 30, 40, 50, 60 minutes at 110oC) with defined limit of 12% for its moisture content and the appearance. So, the selected sample were 2 (a1-1 0.5 cm, 200oC, 40 minutes’ oven time, 20 minutes frying time and b2-1 0.5 cm, 150oC, 60 minutes’ oven time, 20 minutes frying time). In addition, the jerky was accepted by the SNI for microbial contamination, protein content (>18%) and moisture content (<12%), for fat content both sample were high than the standard (<3%). Furthermore, from the sensory aspects, that the most acceptable jerky was beef jerky and the 2 samples ware significantly different with beef jerky.
Keywords: Gurami, Oven, Frying.
