Abstract

The research was aimed to determine the effect of addition of kecombrang (Nicolaiaspeciosa Horan) extract at varied concentration on the quality of the smoked catfish selais (Crytopterusbicirchis). The research was used experimental method and composed as randomized block design (RBD). The treatment was addition of  kecombrangextract into the fish meat at different concentration, consisting of 4 levels, namely: catfish selais without the addition of kecombrang extracts (K₀), catfish selais with addition of kecombrang extracts 3% (K3), catfish selais with addition of kecombrang extracts 6% (K6) and catfish selais with addition of kecombrang extracts of 9% (K9). The smoked catfish products then were stored for 0 days, 15 days, 30 days and 45 days at room temperature. The results showed that the different concentrations of the kecombrang extract solution highly significantly affected to the organoleptic value (appearance, taste, aroma and texture), moisture content, total phenol, total acid, pH, antioxidant activity of the smoked catfish produced,  but significantly affected to the value of TBA. The highest quality of the smoked catfish was produced by the control treatment, which was without kecombrang added (K0) as indicated by the highest value of organoleptic characteristics. The smoked catfish selais was appeared intact, clean, brown, shiny specific types, smelt distinctive aroma of smoked fish, tasted good and tasty, and textured intact, clean, brown, shiny specific species.  The smoked catfish contained water of 32.46%, total 1:15 ppm phenol, 4.73% total acid, pH 6.86, TBA 4.02mg/kg, and antioxidants 62.81%.     Keywords: Crytopterusbicirchis, Nicolaiaspeciosa, kecombrang extract, smoked catfish

Abstract

The aim of the research was to determine the effectiveness of smoking method implemented forproducing katsuobushi (woody smoked fish). The processes were distinguished into two methods, namely: liquid smoking (Pc) and traditional smoking (Pt). Skipjack katsuobushi produced were then evaluated for their quality, including: the value of organoleptic, the value of pH, the content of moisture, acids, and phenols. The results showed that the quality of the katsuobushi produced by implementing the liquid smoking method was significantly different from that produced by implementing traditional smoking one. The value of the odor, flavor, and the content of moisture, phenols and acids, katsuobushi skipjack produced by liquid smoking methods were higher, whilst the value of colour and pH were lower and significantly different than those produced by implementing traditional smoking. Both kinds of katsuobushi skipjack were overgrown by fungi Aspergillus sp. and Penicillum sp. indifferent intensities. The growth intensity of the fungi on the surface of katsuobushi skipjack produced by implementing traditional smoking was higher than that produced by implementing liquidsmoking.Keywords: katsuobushi, liquid smoking,skipjack, traditional_________________
