Mineral Composition and Starch Profile of Improved Varieties of Wateryam (Dioscorea alata) Flour:- Nwafor. Rita C
ABSTRACT
This work determined the mineral composition
and starch of improved varieties of water yam (Dioecorea alata). Improved
varieties of watcryam tubers were procured from National Root Crops Research
Institute, Umudike and used for this study. Wholesome wateryam tubers were
cleaned, peeled, washed and processed into flour. The flour samples were then
subjected to various determinations such as mineral composition, starch quality,
and total sugar. The result of : the mineral content of the wateryam flours
ranged from 246.33-428.73 mg/100g, 3.17-2.91 I i ' . mg/1 00g, 68.52-90.59
mg/l00g for potassium, zinc and sodium respectively. The amylose and
amylopectin content of the flour samples ranged from 29.75-35.9 I% and
64.09-70.25% for amy lose and amylopectin contents respectively. The total
sugar content ranged 5.22-5.79 %. This I study revealed that wateryam flour
possesses nutrients with health benefit.
