Chinova Bioworks recently received a No Questions Letter from the U.S. Food and Drug Administration (FDA) regarding its Generally Recognized As Safe (GRAS) Notice No. GRN 000997 application for Chiber™ Mushroom Fiber, a natural food and beverage preservative. Chiber is a natural mushroom fiber derived from the upcycled stems of white button mushrooms. The fiber functions as a natural preservative that can be used to improve the quality, freshness, and shelf life of various food and beverage products such as cottage cheese, plant-based meats, and hummus.

Prior to receiving FDA’s No Questions Letter, Chinova Bioworks contracted an independent, expert panel of scientists to evaluate the company’s GRAS conclusion in accordance with scientific procedures under 21 CFR 170.30(a)(b). Cinova Bioworks also enlisted the guidance of Intertek to assist the company in developing and implementing the necessary tests and to prepare Chinova Bioworks for its GRAS evaluation.
