| Popis: | The preservation potentials of phenol produced by hardwood, Tectonia grandis and some selected indigenous preservatives on smoked Clarias gariepinus were investigated in this study. A sample size of 168 catfish was pre-treated with single (10.0% salt (FS), 10.0% lime (FLM), 10.0% pepper (FPP),) and combined (5.0% salt and 5.0% lime (FSL), 5.0% salt and 5.0% pepper (FSP), 5.0% lime and 5.0% pepper (FLP), 3.3% salt, 3.3% lime and 3.3% pepper (FSLP)), untreated serving as control. The fish samples were smoked at 90.0±5.0ºC for 16 hours, stored under ambient conditions for twelve weeks. Phenol (mg/kg) and Total volatile base-Nitrogen (TVB-N, mgN/100g) were determined at 0, 2, 4, 6, 8, 10 and 12 weeks using official methods of analysis of the Association of Official Analytical Chemist. Phenol levels ranged from 1.21±0.01 to 1.31±0.00 mg/kg in untreated samples and 1.16±0.00 (FS) to 1.33 ±0.00 (FLM). Mean values of Total Volatile Bases in Nitrogen (TVB-N) were significantly different (p |
