Abstract

Coconut oil is a valuable commodity with diverse applications in food, cosmetics, and pharmaceuticals. The extraction process plays a crucial role in determining the quality and yield of coconut oil. Temperature is a critical parameter that affects the efficiency of the extraction process.This study aimed to investigate the effect of temperature on coconut oil extraction using a solvent extraction method, optimizing the extraction process, and providing insights into the relationship between temperature and oil yield. A laboratory-scale solvent extraction method was employed, where coconut oil was extracted from shredded coconut at different temperatures (30°C, 40°C, 50°C, 60°C, and 70°C) using petroleum ether as the solvent. The yield of oil extracted was measured and calculated as a percentage of the initial weight of coconut used.The results showed a significant increase in oil yield with increasing temperature, with the highest yield obtained at 70°C. The yield increased from 26.29% at 30°C to 32.70% at 70°C, indicating a 24.5% increase. The study demonstrates the importance of temperature optimization in coconut oil extraction, providing valuable insights for the industry.This research contributes to the existing body of knowledge on coconut oil extraction, highlighting the potential for process optimization and improved productivity. The findings have important implications for coconut oil manufacturers, providing a basis for the development of more efficient and effective extraction processes.

Abstract

Mild steels composed by two main elements, they are iron (Fe) and carbon (C) elements which is  widely used in industry  because of its resistance and more affordable in terms of cost  than stainless steel, but their weakness is that they have low corrosion resistance. One way to modify mild steel is by coating them with antioxidant compounds that can delay, slow down, and prevent lipid oxidation process, which is obtained from(Chrysophyllum-Albidum) Udara seed extract. This research work is aimed at producing organic corrosion inhibitor from(Chrysophyllum-Albidum) Udara seed extract. Also, to utilize this organic corrosion inhibitor as a substitute for chemical corrosion inhibitors which contain toxic compounds, and determining the corrosion inhibition efficiency of the Udara seed extract in Hydrochloric acid medium. This was carried out by weighing the mild steel pieces. Udara seed extract was also weighed and added into each of the transparent glass bottles that was used in the experiment. However,  10.0g Udara seed powder was added into bottle 1 containing 0.5m of the dilute tetraoxosulphate (vi) acid. 20.0g to bottle 2, containing the same concentration of the  acid.  30.0g to bottle 3, 40.0g to bottle 4, containing 0.5m of the dilute tetraoxosulphate (vi) acid. And 50.0g to bottle 5 containing the same acid, and Finally, bottle 6 was containing the mild steel metal and the dilute tetraoxosulphate (vi) acid. It was observed that the Udara seed extract effectively inhibited mild steel corrosion in H2SO4 solution. Inhibition efficiency was observed to improve with increase in concentration of the extract. It was generally observed that inhibition efficiency was low at the first hour and with the blank and the first concentration and gradually increases by the preceding hours and concentrations. Weight loss increased with increase in time portraying retardation in the inhibitor efficiency with increase in time.

Abstract

This study explores the potential of utilizing agricultural by-products, specifically plantain peels, as a source of caustic potash for producing high-quality black soaps from palm oil and palm kernel oil. The objectives were to evaluate the physicochemical properties and efficacy of these soaps in addressing various skin conditions. Plantain peels were sun-dried, burned, and processed to extract potassium hydroxide, which was then used in soap production. The results show that both soaps exhibited beneficial properties, with the palm kernel oil soap displaying a softer texture. The study highlights the potential of these black soaps in providing effective skincare solutions for common dermatological concerns, while also promoting sustainable utilization of agricultural by-products.
