Abstract

Orange-fleshed sweet potatoes (OFSP) possess carotenoids, which is a precursor of vitamin A. Planting time and processing methods are believed to affect carotene content of orange-fleshed sweet potato storage roots. Since OFSP are a rich source of  Î²-carotene, it is essential to determine whether sweet potato carotenoids are stable during storage. The changes in dry matter and carotenoids were studied at regular intervals during 35 days of storage in 10 orange-fleshed sweet potato clones at Central Tuber Crops Research Insititue, Thiruvananthapuram, Kerala, India. There was a significant variation in the content of total carotenoids (10.32 . 13.99 mg 100g  -1 f.w) and β-Carotene (9.02 . 12.16 mg 100g-1 f.w) among the clones. A gradual increase in dry matter from 24.1 to 25.5% was observed during storage, due to depletion of moisture. There was no significant change in total carotenoids and β-carotene content in the OFSP clones during the storage period. The results of the study indicated that the total carotenoids and β-carotene in sweet potato storage roots had high stability during storage.
