Sweet potato, starch “champion”

In 2014, experts from the Sweet Potato Research Institute of the Chinese Academy of Sciences conducted a comparative evaluation of the main nutritional qualities of sweet potato tubers of different flesh colors. Among them, the content of starch is higher in sweet potatoes.

Sweet potato tubers have a lighter internal color, higher starch content, a dry mouthfeel, and a lighter sweet taste. Because there is a lot of starch, low sugar content, the taste is not so sweet, and it is not too fragrant when roasted, so it is not suitable for roasting. Overall, the health advantages of white meat sweet potatoes are less obvious than varieties of other colors.
