Thesis Abstract
ABSTRACT
Starch from tigernut was isolated by wet milling process and physico-chemical properties of native and modified tigernut starches (cyperus esculetus) were analyzed. The carboxymethylated modified starch had highest amount of protein (0.45%) fibre (0.25%) and moisture content (14.96%) while natives had highest amount of fat (0.60%) ash (0.17%) starch (77.90%) and amylose 17.71%. the physicochemical analysis showed that native tigernut starch had the highest valve of total solid (86.60%) and PH (6.63) while hydrogen modified starch had highest amount of TTA (0.495%). The study therefore had an effect proximate and physicochemical.
