Physicochemical, organoleptic and nutritional characteristics of four sweet cassava (Manihot opi) varieties

Abstract

There exist a wide variety of tropical tubercles in Martinique French West Indies (F.W.I.). This study was carried out in order to investigate the development of local varieties of sweet cassava (Manihot opi). The purpose of this research was to enhance knowledge of the nutritional and agricultural characteristics of these tubers. The first step in the research project was to carry out a survey and screening of selected varieties, which was undertaken by the local department of agriculture throughout the region of Martinique. Phenotypic characterization and identification were then established. The four varieties were distinguished from each other by phenotypic, organoleptic, physicochemical and nutritional characteristics. Sweet cassavas in Martinique are richer in nutritional compounds and vitamin C than ordinary potatoes. Their sensory specificity, high nutritional value and suitability for industrial processing have also been highlighted. Variety KM07 seemed to offer the best compromise between size, nutritional profile and sensory characteristics and would therefore be recommended for production.

Keywords: Martinique, Manihot opi, physicochemical characteristics, nutritional characteristics, sensory profile, sweet cassava, gallic acid equivalent (GAE).
