Physicochemical properties of starches and flours of cassava accessions from Western Eram, Indonesia

Abstract

Western Ceram in the Maluku Province, Indonesia, has a great diversity of cassava. We have previously collected more than one hundred accessions from the area and identify several of those with promising agronomy characteristics. The examination part detailed here was planned for describing the physicochemical properties of starches and flours from the promising cassava clones possessing different tuber flesh characteristics. Starches and flours were produced or extracted from clones UP-uj-25, UP-uj-26, UP-uj-56, UP-uj-73, UP-uj 93, as well as var. Malang 6 and C4 as a comparison. Physiochemical analyses of the starches and flours conducted on the contents of carbohydrate, protein, fat, starch, ash, total sugar, HCN, as well as starch resistance, paste clarity, swelling power, solubility, viscosity, crystallinity and shape of granules; standard procedures for each analysis employed. Starches and flours from the promising clones and comparison varieties showed variations in chemical and physical properties; however, in general, they showed similarity crystallinity/crystal type (type C).
