Characterization of crude starch extract of wild cassava tuber (<i>Ampelocissus africana</i>)

Abstract

Ampelocissus africana (wild cassava tuber starch) is a starch-rich tropical plant that has been used as a part of diet for people for several years, particularly during times of famine. Its stalk and foliage are used to treat many ailments. In this study, the tuber starch extracted from wild cassava tuber (Ampelocissus africana) was evaluated. The iodine test indicated a starch content of 10.12%. The isolated starch was observed to be odorless and tasteless, with a faint ash-off white color. SEM analysis revealed that the starch granular morphology was globular and oval. Other found properties are: ash (2.5%), moisture content (69.00%), fat (1.5%), fibre (5.5%), crude protein (4.46%), and accessible carbohydrate (84.54 %). These findings revealed that wild cassava tuber starch is a good source of carbohydrates, primary starch, which has a wide range of household and commercial applications.
