Ustilago Esculenta/Zizania Latifolia Stem Ferment Extract is a unique cosmetic ingredient derived from the fermentation of the stems of Zizania latifolia, commonly known as wild rice or Manchurian wild rice, by the fungus Ustilago esculenta. This ingredient is also sometimes referred to simply as “wild rice stem ferment extract.” The fermentation process involves the breakdown of the plant material by the fungus, resulting in a rich, bioactive extract that is prized for its skin-conditioning properties.
Historically, Zizania latifolia has been cultivated and consumed in various Asian cultures for centuries, not only as a food source but also for its medicinal properties. The use of Ustilago esculenta, a fungus that naturally infects the plant, has been documented in traditional practices, particularly in Chinese cuisine where the infected stems are considered a delicacy. The transition from culinary to cosmetic use is relatively recent, driven by the growing interest in natural and fermented ingredients in skincare.
The production of Ustilago Esculenta/Zizania Latifolia Stem Ferment Extract begins with the careful selection of Zizania latifolia stems, which are then subjected to a controlled fermentation process using Ustilago esculenta. This fermentation process enhances the bioavailability of the plant’s nutrients and creates new bioactive compounds that are beneficial for the skin. The resulting extract is then filtered and purified to ensure it is safe and effective for use in cosmetic formulations.
