Abstract
This study was aimed to describe the profile of traditional striped catfish (Pangasius hypophthalmus Sauvage) smoking in Province of Riau, Indonesia. The study was collected data about the method of traditional smoking by survey. The survey was followed by the sampling and the laboratory analysis on the profile of produced smoked catfish and the best type of firewood used for fuel and smoke source. The laboratory analysis includes physicochemical characteristics and sensory analyses. Results showed that fish smoking in Riau is applying direct hot smoking method. The smoking process is conducted in two stages. The first stage is roasting at the smoking temperature of 60-90°C for four hours, continued with drying stage at the smoking temperature of 40° C for about five hours. The product of smoked catfish was blackish brown, shiny, dry and clay textured, and the weight reduced to 31% from initial weight. The best type of firewood was Laban (Vitex pubescens Vahl). The smoked catfish using Laban firewood as smoke source showed the highest content of total phenols 0.060 ± 0.003%, with the value of aw 0.680 ± 0.05, and pH 6.65 ± 0.12. The smoked catfish produced was the most preferred by panelists, especially its appearance and odor, with the average of sensory value 7.4. This sensory value is above the minimum standard value 7.0 determined by the Agency of National Standard in Indonesia for smoked fish.
