Proximate composition and functional properties of Bulma cotton [Bombcapsis glabra] seeds

BOMBCAPSIS glabra seeds has percentage protein [16.50], crude fat [34.8], crude fibre [8.70] and ash [3.52] contents. The predominant mineral was potassium, 791mg/100g of sample. Palmitic acid was the predominant fatty acid constituting 75.0% in the seeds oil. The amino acid pattern of the seed flour showed that Aspartic and Glutamic acids were the major amino acids and that the seed flour was deficient in Leucine and Cystine. Physicochemical analysis of the seed oils showed that they could be classified as non-drying oils. Bombcarpsis glabra seed flour had high water and low oil absorption capacities 255.0 and 91.8%, respectively. It could serve as a good gelating agent with at least gelation concentration of 2.0%. The flour had poor foaming capacity but good foaming stability

Hydrochloric acid leaching of minerals from nigerian soil

Effects of particle size on the leaching of some metals [Mn, Cu, Fe and Zn] from soil was studied at room temperature and different hydrochloric acid concentrations. It was found that the metal concentration in the leachate decreases steadily with increasing leaching time up to a limit with exception of iron. However, the metal concentration observed at 75 micro m and 288 micro m did not differ largely after a long time of leaching. The highest metal concentration was obtained using a particle size of 75micro m. A linear relationship was established between the plots of inverse of concentration in the leachate and inverse of leaching time. This observation confirms the validity of the proposed equation for the correlation of the concentration in the leachate with leaching time. The correlation of the predicted leaching concentrations with the experimentally determined ones showed only 11.0% deviation
