Abstract
Aims: The purpose of this research was to perform the physical and chemical study of the composition and the quality of the fillet of Hoplias malabaricus (Traíra) and Leporinus friderici (Bloch, 1794) collected in Pirativa River-Santana-Ap.
Study Design: This study was chosen in the areas on the banks of Pirativa river in anthropized and non-anthropized areas in the city of São Raimundo, at coordinates N 00 02'08,9 "W 051 15 '32.3" in Santana-AP.
Place and Duration of Study: the research was conducted in Pharmacognosy and Phytochemical Laboratory of the Course of Pharmacy from January to September of 2014, and in the Fish Processing Laboratory of the Federal University of Amapá (UNIFAP), from July to September of 2014.
Methodology: The physical and chemical parameters adopted in this research were pH, humidity, Waste from Incineration (Ash), Lipids and Total Volatile Bases. All the tests were carried out according to standards in the Adolfo Lutz Institute.
Results: The yield values were 48.30 and 46,632% respectively for Hoplias malabaricus (Traíra) and Leporinus friderici (Aracu). Regarding the physical and chemical parameters, the species Hoplias malabaricus (Traíra) and Leporinus friderici (Aracu) presented, respectively, pH 6.80 and 7, humidity 70 004±4:57 and 2:44±65.55%, ash 2.88±0.74 and ±3:50 1:51%, lipid values of 10:50 and 11.90% indicating high molecular weight lipids, and volatile bases ±0.01 1.76±1.69 and 0:03.
Conclusion: Attention should be paid to the proper packaging and treatment of fillet, because external factors, from the fish catch to the market of its by-products, influence the quality and nutritional value.
