Three Nigerian condiments from locust bean, melon, and soya bean were prepared by the traditional technique of uncontrolled fermentation and then partly defatted by hexane and di-ethyl ether extraction respectively. Proximate analysis and consumer preference tests were conducted. Results showed that while crude protein, ash and fibre contents remained virtually unchanged, the carbohydrate contents of the treated condiments (derived by difference) increased remarkably. The increase was associated with the significant reduction of about 50% (p = 0.05) in lipid contents of the three condiments. The observed solvent effect correlated positively with panelists' preference rating for the treated locust bean and melon condiments. Except with the soya bean condiment, higher mean scores were observed after the solvent treatment for the four sensory attributes assessed. However, condiment-type and treatment notwithstanding, colour and odour appear to critically determine the level of acceptability of condiments.

The study was aimed at investigating the nutrient and tannin composition of fermented legume seeds (oil bean, castor oil bean and African locust bean) used as food condiments in Nigeria. The legume seeds were purchased from local retailers, cleaned and subjected to varied fermentation periods. Standard assay techniques were adopted to analyze the parameters selected for use. The 4-day fermentation period caused the highest increases in protein and tannin and decreases in ash, lipids and non-protein nitrogen (NPN). The pulp of African locust bean had more protein an ash and the oil bean seeds less lipids and NPN. Fermentation times had varied effects on mineral levels. Fermentation for 4 d increased zinc, sodium and phosphorus except sodium for the African locust bean. The pulp had lower Zn and phosphorus than the seed. Fermentation for 4 d offers a greater advantage over other periods for production of nutritious and cheap food condiments in Nigeria.
