Abstract

Crude protein and mineral content in six sweet potato cultivars and total carotenoids in four orange‐flesh cultivars after different storage treatments were determined. On a fresh weight basis, crude protein between cultivars ranged from 1.36‐2.13 g/100g, phosphorus from 38‐64 mg/100g, potassium from 245‐403 mg/100g, calcium from 20‐41 mg/100g, magnesium from 13‐22 mg/100g and total carotenoids from 5‐11.5 mg/100g. Carotenoids slightly increased after curing and short term storage at either 7o, 15.6o, or 26.6oC. Centennial contained the most protein, phosphorus, magnesium, and carotenoids of all cultivars. Travis contained the lowest amount of protein, phosphorus and potassium, but more carotenoids than Jewel or Jasper. Copyright © 1985, Wiley Blackwell. All rights reserved
