Orange-fleshed sweetpotato (OFSP) purée can be used to substitute wheat flour by 25-60% depending on the product, without affecting the quality of baking procedures. We developed a safe, vacuum-packed shelf-stable purée that lasts 3 months without refrigeration, using locally available preservatives. By carefully washing the roots, it is not necessary to peel them. This has enabled a high-fiber purée (Fig. 1) to be developed that significantly improves the profit margin for purée processors.
