The yam peels dried powder was subjected to X-ray diffraction analysis, and it was examined for proximate and biochemical composition. The result of the biochemical analysis of the yam peels showed the following: holocellulose (57.93 %) [cellulose (29.02 %) + hemicellulose (28.91 %)], and lignin (27.43 %), while the proximate analysis showed the following: moisture (11.11 %), ash (5.93 %), and volatile matter (68.4 %). Consequently, the X-ray diffraction pattern shows the presence of amorphous and crystalline region in the sample. The result showed that the yam peels possesses low lignin and high holocellulose content. This study indicate that the yam peels are potential candidates for bioethanol production.

The analytical assessment of properties such as proximate analysis, elemental composition, and calorific value are very important to know the coking qualities of the coal. The proximate analysis showed that the moisture content, ash content, volatile matter, fixed carbon and calorific values of the coal are; 1.86%, 18.82%, 43.74%, 53.58% and 5405.15 Cal/g respectively. Based on the result of the proximate analysis, the coal is of good metallurgical coke quality from an industrial prospective and heat generation is to be considered. Elemental analysis shows that due to the low heavy metals, low sulfur content and ash content of the coal, utilization of the coal within a safe environment is feasible with just a little environment impact and make it suitable for blending with strong coking or caking properties.

This research studied the effect of acetylation on the physicochemical properties of lignocellulosic samples. Oil palm empty fruit bunch (OPEFB), pride of Barbados Pods (POBP) and cocoa pod (CP) samples were acetylated at 70C for 90 min, in the presence of n–bromo succinimide (NBS) catalyst using a solvent free method. The modified (acetylated) and unmodified (unacetylated) samples were further characterized using scanning electron microscope (SEM) and X–ray diffractometer (XRD) analysis. The results showed that acetylation did not affect the ash content significantly but reduced the moisture content and bulk densities (compacted and uncompacted) of the lignocellulosic samples while the XRD analysis showed that acetylation reduced the cr...

The importance of vegetables from the point of view of the food industry is determined by their complex chemical content that is important to the human body and this includes organic substances (lipids, proteins, carbohydrates and organic acids). This study examines comparatively the levels of lipid compositions in the samples of dried carrot (Daucus carota L) and cucumber (Cucumis sativus L). The fatty acid, phospholipid and sterol compositions were determined from the samples using Gas Chromatography method. The most concentrated fatty acid (%) was linoleic acid (C18:2) (54.04 and 57.62) and the least was arachidic acid (C20:0) (0.01 and 0.01) for Daucus carota and Cucumis sativus, respectively. The result showed the quality parameters of fatty acids investigated in the Daucus carota and Cucumis sativus samples as: SFA (23...
