Abstract
his study was aimed to determine the retention of bioactive fatty acids and oxidative stability of fish powder (FP) supplemented
extruded products. The Labeo rohita fish meat was minced, microwave vacuum dried, and extruded. Product formulations
containing FP (0-25%) and semolina (75-100%) were optimized using response surface methodology. The maximum bioactive
fatty acids retention was 94.84% in the final product. The highest values of polyunsaturated fatty acids (PUFAs) were 87.97%
and 85.66% at 25 °C for 30 and 60 days. Maximum TBARS values were 0.42 and 0.44 mg MDA/kg at 25 °C for 0 and 30 days,
respectively. The highest carbonyl contents were 6.02, 7.67, 9.37 nmol/mg protein for 0, 30, and 60 days of storage at 25 °C,
respectively. The moderate barrel exit temperature (125 °C) and feed moisture contents (20%) and high screw speed (150 rpm),
FP (25%) exhibit the highest retention of PUFAs in a product
