Preservative Synergy of Phenol from Tectonia grandis and Some Indigenous Preservatives on Smoked Clarias gariepinus

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 168 catfish was pre-treated with single (10.0% salt (FS), 10.0% lime (FLM), pepper (FPP),) combined (5.0% 5.0% (FSL), (FSP), (FLP), 3.3% salt, (FSLP)), untreated serving as control. fish samples at 90.0±5.0ºC for 16 hours, stored under ambient conditions twelve weeks. Phenol (mg/kg) Total volatile base-Nitrogen (TVB-N, mgN/100g) determined 0, 2, 4, 6, 8, 10 12 weeks using official methods analysis the Association Official Analytical Chemist. levels ranged from 1.21±0.01 to 1.31±0.00 mg/kg 1.16±0.00 (FS) 1.33 ±0.00 (FLM). Mean values Volatile Bases Nitrogen (TVB-N) significantly different (p<0.05), ranging 14.24±0.02 31.38±0.03mgN/100g 11.06±0.03 128.60±0.04 mgN/100g (FPP) treated. use preservative should be avoided it must have promoted autolytic process which led formation high level compounds. This superseded phenolic effect T. after 4 storage during C. could re-smoked fresh impartation phenol.
