    Thevetia peruviana seeds cake were defatted and then treated with varying concentrations each of hydrochloric acid, sodium hydroxide and calcium hydroxide solutions. Each product of hydrolysis was extracted with chloroform to isolate aglycones, the toxins of the seed. Various concentrations of hydrochloric acid and sodium hydroxide solution effected complete detoxification. Only 0.4M and 0.5M of calcium hydroxide solution detoxified the seeds completely. Albumin and globulin determination by biuret method confirmed that various concentrations of the hydrolyzing agents increased the quantity of extractable albumin and globulin in the cake. Each solution used for the detoxification had closely related trend on the total albumin and globulin value of the treated cake. Higher quantities of albumin and globulin were recorded in the samples treated with various concentrations of calcium hydroxide solutions. The study suggests that calcium hydroxide at high concentrations appear to be the best detoxicant.

    Preservation of Smoked African Catfi sh, Clarias gariepinus Burchell against Dermestes maculatus De Geer (Coleoptera: Dermestidae) using Neem Seed Oil-iodized Salt Mixtures

    Dermestes maculatus is a major fish pest causing serious damage when left uncontrolled. Th is work identifies the fatty acids of Nigeria-obtained neem seed oil (NSO) and the potential of different mixtures of the NSO and iodized salt in the control of the pest. Seven fatty acids: palmitic acid (18.09%), linoleic acid (33.73%), stearic acid (14.37%), oleic acid (13.4%), octadecanoic acid (12.93%), 9, 12– octadecadienoic acid (1.47%) and arachidic acid (3.33%) were identified in the NSO. Percentage of D. maculatus adult mortality (100%) observed in fi sh treated with 0.00 μl NSO + 0.50 mg salt, 100 μl NSO + 0.125 mg salt and 0.00 μl NSO + 0.25 mg salt was significantly (p<0.05) different from mortality observed in untreated fish (31.25%). Percentage of live larvae (0.0%) in fi sh treated with 0.50 mg salt + 0.00 μl NSO, 100 μl NSO + 0.125 mg salt, 0.00 μ1 NSO + 0.25 mg salt and 50 μl NSO + 0.125 mg salt was significantly lower than 63.97% observed in the control. Percentage of weight loss of untreated (75.10%) and 50 μl NSO-treated fi sh (69.65%) was significantly higher than values obtained from fi sh treated with 0.5 mg salt (26.93%), 100 μ1 NSO + 0.125 mg salt (25.73%) and 0.25 mg salt (23.63%). Application of NSO-iodized salt did not change the colour and odour of treated fish. Consumers significantly rejected fi sh treated with ≥ 50 μl NSO.
