Ube powder, also known as freeze-dried purple yam powder, is derived from the dried tubers of Dioscorea oppositae thunb., a perennial vine plant belonging to the Dioscoreaceae family. Cultivated primarily in regions like Yunnan, China, these purple yams are renowned for their vibrant hue and rich nutritional profile.
The production of freeze-dried purple yam powder involves advanced freeze-drying technology. This process involves freezing the fresh purple yams and then subjecting them to a low-pressure environment, where the ice sublimates directly into vapor, bypassing the liquid phase. This method preserves over 95% of the original nutrients, flavor, and color of the yams, resulting in a fine, soluble powder that retains its potency and quality.
