Patented antimicrobial: A future silver lining in packaged food safety?

摘要

Silver has been widely recognized and accepted for decades as an antimicrobial agent used for treating surfaces. To keep up with the times, Pure Bioscience, a company dedicated to food safety solutions, has created and patented technology, silver dihydrogen citrate, trademarked "SDC." The company states that SDC is the first new-generation, patented antimicrobial to be registered with the U.S. Environmental Protection Agency in more than 30 years. A committee of independent experts critically reviewed efficacy and toxicity data for SDC and the SDC-based Pure Hard Surface disinfectant and food contact surface sanitizer. It found no evidence that SDC demonstrates a hazard to the public when used as a contact biocide on food contact surfaces and food-use utensils and therefore concluded its use as Generally Recognized As Safe (GRAS). This sets the stage for additional GRAS projects to determine SDCs suitability as an indirect and direct food additive in food processing.
