Effect of locality on carotenoids stability in Malaysian orange sweet potato (Ipomoea batatas) tuber flesh

Carotenoids are bioactive antioxidant pigments with pharmaceutical potential. Carotenoids such as α-carotene and β-carotene react as provitamin A in human body, while lutein and zeaxanthin are two major components of the macular pigment of the retina. Due to its high carotenoids and pro-vitamin A co...

The carotenoid content in sweet potato or as locally known Keledek in Malaysia were determined using spectrophotometry and high performance liquid chromatography HPLC analysis. Objective: This study aimed to assess the carotenoids content stability in five different localities in Malaysia (Kelantan, Pahang, Terengganu, Selangor and Perak) of orange sweet potato tuber. All analyses were carried out in triplicate. Results: Results of this study revealed that the orange sweet potato (OSP) from Kelantan showed the highest total carotenoids content. For individual carotenoids, β-carotene ranged from 1123.85±0.04 μg/g to 399.4±3.62 μg/g DW. Zeaxanthin was detected only in Kelantan OSP 13.01±0.00 μg/g DW.
