Abstract:
Modification is proximate composition fatty acids chemical quality as well as changes in organoleptic traits were study in raw Cat fish fillets (Clarias gariepinus), pan-fried fillets in sun flower oil for 4 minutes and reheated fried cat fish fillets (in conventional oven for 15 min. at 80℃) after storage for one week at 5±1℃ and for one month at 20±2℃. after frying of cat fish fillets the moisture, Saturated Fatty Acids (SFA),Monounsaturated Fatty Acids (MUFA),Total Volatile Basis Nitrogen (TVBN) and Trymethylamin Nitrogen (TMAN) were reduced while, protein, fat, ash, polyunsaturated Fatty Acids (PUFA) Thiobarbeturic Acid (TBA) and Peroxide Value (PV) were increased due to chilling and frozen storage of fried catfish fillets, the gross chemical composition showed no significant changes ( p˃ 0.05), whereas slow increase in SFA and slow decrease in (MUFA) and ( PUFA) was found all chemical quality (TVBN,TMAN,TBA, and PV) of Cat fish fillet fried and stored at 5±1 ℃ and -20±2℃ were higher ( p˃0.05), as compared with the samples after frying directly. Organoleptic evolution scores of colour, taste, flavor, juiciness, and overall acceptability were highest for samples after fried directly while it showed significant decrease (p˃0.05) after storage at 5±1℃ and at -20±2℃ for one month respectively.
