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 7 o , 15.6 o , or 26.6 o C. 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.
