Backed by a $1.82 million NCInnovation grant, Appalachian State University professor Dr. Brett Taubman and his research team are transforming surplus North Carolina sweetpotatoes into a first-of-its-kind, plant-based milk. The initiative — Rootsii — also provides undergraduate researchers with hands-on experience in developing a new agricultural product line. The startup will produce milk, creamers, ice cream, yogurt and other fermented foods such as sweetpotato-based miso and fermented hot sauce.
