Abstract

Cassava is a dominant staple food for many developing countries, particularly, in humid and sub-humid tropics. In this study, the proximate composition and cyanide content of cassava tuber grown in Jimma Zone were investigated. Cassava samples were collected from five selected Woredas (Districts) of the Zone, where the plant usually grows. Nutritional compositions such as crude fat, protein, and fiber as well as cyanide contents were considered in this study. Accordingly, the crude fat, protein, and fiber content of the studied cassava root ranged from1.38-3.06%, 1.32-1.90%, and 1.58-2.96%, respectively. The results of the nutritional composition of analyzed cassava root samples were rich in crude fat, protein, fiber, and carbohydrate. The level of cyanide gives its value compared to the limits set by the World Health Organization was low and it may not cause harmful effect on human health.

Highlights

Cassava (ManihotesculentaCrantz) is a woody shrub native to South America [1]
Cassava samples were collected from five Woredas of Jimma zone; Mana with altitude of (1786 m), Sakachekorsa (2107 m), Dedo (2096 m), Sokoru (1620 m), Gomma (1805 m), above sea level were selected purposively and representative samples were obtained randomly
Cassava tuber has a major potential as a substitute for other types of flour or it can be used by mixing it with other flours

Summary

Introduction

Cassava (ManihotesculentaCrantz) is a woody shrub native to South America [1]. The plant is known by its edible starchy tuberous root. It is a drought tolerant, staple food crop grown in tropical and subtropical areas where many people are afflicted to under nutrition, making it a potentially valuable food for developing countries [1]. It is widely used in food security because; its mature edible tuber can be stored in the ground for up to three years. Because of its capability in producing efficient food energy, availability throughout the year, tolerance to extreme stress conditions, and suitability to present farming and food systems in Africa, cassava plays a role to alleviate the African food crisis [2]
