Examination of White Specie Onion for Production of Oil: Integration for Pharmaceutical Production

Abstract

Research work was carried out to examiner the characteristics of oil produced from white specie of onion obtained in Nigeria. The following functional parameters were examined with the

refractive index of 1.34926, density of 1.1036g/cm³, viscosity of 2.45cst, iodine value  of 28.1083%, saponification value of 10.94%, free fatty acid (FFA) of  11.264%, peroxide value of 45% and acid value of 2.104%. The result obtained reveals the significance of white onion specie in the production of pharmaceutical oil as a medicinal for human utilization. The research demonstrates the usefulness of steam extraction mechanism in the production of pharmaceutical oil as well as the characteristics of the end product obtained, which the evaluation of the functional parameters indicates the reliability of the product.
