Abstract

Beta carotene is one of carotenoids which serves as a precursor of vitamin A, pigment essential for eye health. In this study will be to compare the levels of beta-carotene in sweet potato tubers fleshy orange with the presentation of different treatments. Presentation by frying, boiling, steaming. Testing of beta carotene in sweet potatoes orange -fleshed tubers include qualitative and quantitative tests .Qualitative test sample was based on the color reaction if the sample was added a few drops of reactant TCA will form a bluegreen color and also qualitative analysis using wavelength , if the wavelength of the samples and the raw beta carotene almost approaching the sample is positive for beta carotene which the wavelength of 463 nm raw betacarotene . Quantitative assay using a UV- Vis spectrophotometry . The research showed high levels of beta carotene on the average of the original sample of 0.0134 % 0.0076 % of the sample fried steamed sample of 0.0053 % and 0.0033 % of boiled samples. Keywords : Sweet potato , beta kroten , UV - Vis spectrophotometry.
