ABSTRACT
The objective of this study was to describe the fresh cooled pink-shrimp (Penaeus brasiliensis and Penaeus paulensis) lipid. The total lipid content was 1.13 +/- 0.09 g/100 g while fatty acid profile showed 32.9 saturated, 20.4 monounsaturated and 40.5 polyunsaturated. Eighteen fatty acids were detected, seven saturated (140, 150, 160, 170, 180, 200, 220), four monounsaturated (161w7, 171w9, 181w9, 201w9) and seven polyunsaturated (182w6, 183w3, 202w6, 204w6, 205w3, 225w3, 226w3). The free cholesterol content was 92 to 136 mg/100 g with average of 118 mg/100 g. In same time, was observed the occurrence of free 7-ketocholesterol, a product of cholesterol oxidation, in levels of 0.185 to 0.366 microgram/g. The fatty acid profile was obtained by gas chromatography with a fused silica column Supelcowax 10. The cholesterol and 7-ketocholesterol was determined by high performance liquid chromatography using a mu-Porasil column, normal phase, and a diode array detector.
