Abstract

The aim of this study was to investigate tannins by using a process for utilizing the waste raw material (Anacardium occidentales L. testa) into a useful substance. Tannins are the fourth most abundant plant constituent after cellulose, hemicelluloses and lignin. For separation of tannins, water was used as solvent. Optimization parameters time, temperature and particle size was studied for optimum extraction of tannins from cashew waste testa. During the experiment samples were stored in the absence of heat in a dark container. Moisture content of the samples was estimated.

Keywords: Anacardium occidentales L., solvent, optimization, tannins and testa.
