Purple yam powder is made from tubers of Dioscorea alata L. It is locally known as “ubi”. The preparation process for purple yam powder includes a proper selection of deep purple color “ubi” tuber. The tuber is then washed, steamed, peeled, grated, dried, pulverized, and packaged.

The ubi tuber and its processed products contain a high level of starch, making it a rich source of calories in the diet. The product is highly regarded for its appealing color and antioxidant properties due to its anthocyanin content. It is a very popular food ingredient in bakery and confectionary products among others.
