Determination of some toxic gaseous emissions at Ama Industrial Complex, Enugu, south eastern Nigeria

A study of some gases emitted from three industries at Ama industrial complex, Nigeria, was carried out using Crowcon Gasman, single gas monitors. Results showed that HCN (0.94 ± 0.16 ppm) and CO (3.17 ± 0.89 ppm) emissions from Brewery were significantly (P < 0.05) higher than those of Bottling Company A (0.46 ± 0.12 and 0.65 ± 0.10 ppm, respectively). NH3, SO2 and NO2 emissions were the...

Mineral content in French type bread with sodium replacement using fluorescence spectrometry X-rays by energy dispersive

The present study aimed to determine the mineral composition of the French type bread with partial replacement of sodium chloride by potassium chloride using the technique of X-ray fluorescence energy dispersive. The excitation energy used was 50 keV and detector operation at -176°C. The detected variations were from 10.16 to 613.69 mg 100 g-1 for sodium and from 211.58 to 958.96 mg 100 g-1 for potassium. The...

Influence of acetylation on the physicochemical properties of composited starches from sweet potato (Ipomoea batatas L.) and water yam (Dioscorea alata L.)

The study investigates the effect of acetylation on the physicochemical properties of composited starches from sweet potato and water yam. Starch was respectively isolated from both sources, dried and subjected to acetylation at different combination. The result shows that the modified starches were of low percentage of acetylation and low degree of substitution. Acetylation increased the water absorption capacity of...
