A study was carried out to study the effect of drying temperature (50, 60, 70°C) and salt concentration (3, 5, 7%) on quality of dried Euthynnus affinis (tongkol). The proximate analysis showed significant different (p<0.05) in all proximate values, especially the protein content (76.66%) of the fish dried at 50oC.. Higher drying temperature and salt concentration tend to produce darker (72.39) dried fish products. Water holding capacity (WHC) of the product was rather low ranging from 3.43-3.66 ml/g sample. The water activity (aw) of the dried fish was 0.76 or less, which is suitable for storage purposes, controlling the microbial growth, inhibit enzyme activity and fulfilled the packaging requirement.
