Investigation of the Tannin and Tanning Potential of Erythrophleum suaveolens (Gwaska)

Abstract

This study is triggered by the need for search of r alternative vegetable tanning materials that is naturally abundant, easily obtainable and offer competitive tanned leather performances. In this study, the physical and chemical properties of leather tanned with Erythrophleum suaveolens (Gwaska) were determined. The result of the shrinkage temperature was found to be the same with Acacia nilotica (Bagaruwa) tanned leather and the tannin content was found to be 29%. From the result obtained in this research, it is evident that Gwaska is a potential plant for the tanning industry, especially the traditional tanneries in Nigeria. Therefore, the utilization of the findings in this study can serve as a practicable and effective means of alternative and sustainable source of tannins for the tanning industry.
