Mango (Magnifera indica) seed kernel from Nigeria were analyzed for proximate composition, inorganic ions, amino acid composition, tannin and fatty acid composition. Mango seed kernel had 44.4% moisture content, 6.0% protein, 12.8% fat, 32.8% carbohydrate, 2.0% crude fiber, 2.0% ash and 0.39% tannin. Mango kernel fat contained high amounts of stearic (46.3%) and oleic (40.0%), while palmitic, linoleic, arachidonic and behenic acids were present in small quantities (<6.6%). Of the inorganic ions detected, potassium (365 mg/100 g), phosphorus (140 mg/100 g), magnesium (100 mg/100 g) and calcium (49 mg/100 g) were present in high levels, while iron, sodium, manganese and zinc were present in small levels (< 11.0 mg/100 g). The mango seed kernel is potentially a good source of nutrients for human and animal feed.

Fruits of Black (African) velvet tamarind (Dialium guineense Wild), separated into pulp and seed, were analyzed for proximate composition, selected inorganic ions and vitamin C. Significant differences (P > 0.001) were observed in the values of moisture (5.9 and 4.9), organic matter (97.5 and 98.2), dry matter (94.1 and 95.1), crude protein (15.7 and 4.2), crude fat (5.4 and 2.6), ash (2.5 and 1.8), crude fiber (6.6 and 2.2) and total carbohydrate (70.6 and 86.6) for seed and pulp, respectively. Expectedly, the level of ascorbic acid was significantly (P > 0.001) higher in the pulp (35.7 mg/100g) than in the seed (6.4 mg/100g). Varying levels of selected inorganic ions were also detected. The black velvet tamarind is potentially a good source of nutrients for human food and animal feed.

The moisture sorption isotherms of cornchips at three ambient temperatures (27, 35 and 40°C) were sigmoidal, a function of temperature and described by the Henderson equation. Storage stability of the product would be enhanced below 27°C and 3.4 moisture content dry basis (d.b.). The isosteric heats of sorption were calculated.
