February 10/Vancouver, B.C./Marketwire -- Functional Technologies Corp. announced that the U.S. Food and Drug Administration (FDA) has reviewed, and issued a "no questions" letter in response to, the generally recognized as safe (GRAS) notification for the company's Phyterra(TM)-branded hydrogen sulphide (H2S)-reducing yeast. Functional Technologies' subsidiary, Phyterra Yeast Inc., had submitted a notice to the FDA, on the view that the yeast is considered GRAS for use in preventing the formation of H2S during the fermentation of alcoholic beverages including red and white wine, champagne, sherry, sake and other rice wines, and beer.
In the letter, the FDA indicates that based on the information provided, as well as other information available to it, the FDA has no questions at this time regarding the conclusion that Phyterra's H2S-reducing yeast is GRAS, under the intended conditions of use. In general, the FDA responds to GRAS notices with letters indicating either that the notice provides a sufficient basis for the GRAS determination and the FDA has no questions regarding the conclusion, or that the notice does not provide a sufficient basis for the determination of GRAS.
