LIPID DISTRIBUTION IN THE MEAT OF JAU (Zungaro jahu) AND THE INFLUENCE OF STORAGE TEMPERATURE ON ITS FAT STABILITY

The aim of this study was to determine the total lipid content in nine different body regions of jau catfish ( Zungaro jahu ), and evaluate the nutritional composition, energy value and lipid oxidation of jau meat during 15 days at 4°C, before (T1) and after freezing (T2) for 105 days at –20°C. The body regions were divided into anterior-dorsal (P1), anterior-medial (P2), anterior-ventral (P3), central-dorsal (P4), central-medial (P5), central-ventral (P6), posterior-dorsal (P7), posterior-medial (P8), and posterior-ventral (P9). Jau catfish contained high protein (20.17%), low lipid (0.60%) and low energy value (88.36 kcal 100g -1 ). The increase of malondialdehyde - MDA (0.2 to 2.5 mg MDA/kg) was more pronounced (P
