They are rich in elements such as anthocyanins, which are not found in other foods—thus, purple sweet potatoes are hailed as the “gem among tubers.”

　　Using purple and regular sweet potatoes as the primary ingredients and traditional production techniques, Luzhou’s Longmatan District has developed these “purple sweet potato starch noodles”—a local specialty—without adding any additives. After testing by national quality inspection authorities, all inspected items met the standards, and the product was honored as one of the “Top Ten Favorite Quality Specialty New Products of Wine City.” It is a purely natural and green food.

　　In recent years, research and cultivation have produced purple sweet potatoes with enhanced nutritional and health benefits. Especially notable is their content of iodine and selenium—elements essential to the human body and known for anti-cancer properties—which are dozens of times higher than those found in regular sweet potatoes. The anthocyanins and other elements they contain are also not found in other foods. Therefore, purple sweet potatoes are praised as the “gem among tubers.”
