An article in Farmers’ Markets Today reports that caffeoylquinic acids, which are known for their antioxidant activities, were found in measurable amounts in sweet potatoes by ARS scientists. The highest levels of the compounds were found in the layer of tissue just under the skin, intermediate levels were found in the interior of the sweet potato, and the lowest levels were found in the skin. The research was published in the Journal of the American Society for Horticultural Science.
