Varietal differences in chemical composition of the sweet potato storage root.

Twelve sweet potato cultivars, grown in the field in Kumamoto, Japan, were analysed for DM percentage, fructose, glucose, sucrose, maltose, beta -carotene and amino acids. DM percentage ranged from 19.2 to 41.3%, fructose from 1.16 to 17.56 mg/g, glucose from 0.60 to 18.05 mg/g, sucrose from 8.9 to 30.9 mg/g, maltose from 1.8 to 131.4 mg/g and beta -carotene from 1.1 to 236.6 mg/100 g FE. The contents of 18 amino acids are tabulated.
