Effects of weight and body parts of siamese catfish (Pangasius hypophthalmus) on the nutritional content

Abstract

The purposes of this study were to determine the nutrition contents and fatty acid profiles in Siamese catfish (Pangasius hypophthalmus) based on weight and body parts (head, body, tail, belly flaps, and fillet). This research was conducted using experimental laboratory methods. The fatty acid profiles were determined using Gas Chromatography Flame Ionization Detector (GC-FID) and the data were analyzed descriptively. The analysis result showed that weight difference and body parts catfish significantly (p<0.05) effected to moisture content, ash, fat, and carbohydrate. Most saturated fatty acids identified in catfish was palmitic acid, which was abundant in the belly flap part of catfish (800-1000) g and the body part of catfish (1001-1200) g. The most abundant monounsaturated fatty acid (MUFA) in catfish was n-9 fatty acids (oleic acid). While, polyunsaturated fatty acid (PUFA), the n-6 fatty acid group (linoleic acid). The n-3 essential fatty acid (linolenic acid, EPA and DHA) is not significantly different between the body parts (head, body, tail, belly flap, and fillet) of catfish. The essential fatty acid content was mostly found in catfish (800-1000) g.
