Yes, purple yam powder (also known as ube powder) is safe to eat when it is produced and processed under proper conditions. It is made by dehydrating and grinding purple yam (Dioscorea alata) into a fine powder, which retains much of the nutritional value and vibrant color of the fresh yam. Purple yam powder is commonly used as a convenient alternative to fresh purple yam in cooking and baking.
