National Food Laboratory Aseptic Validation Medium is used as a general medium to promote growth of aerobic bacteria and facultative anaerobic bacteria present in spoiled food products and is suitable for use in the validation and commissioning of aseptic filling processes. It is designed to recover spore forming organisms that are used to validate many common sterilization processes, such as steam, hydrogen peroxide, or peracetic acid.
Casein peptone provides a source of carbon and nitrogen required for growth of organisms while yeast extract serves as a source of essential vitamins and nutrients. The presence of glucose serves as a fermentable carbohydrate for organisms such as Geobacillus stearothermophilus and other flat sour organisms. The production of acid from glucose is detected by the inclusion of bromocresol purple, which turns from purple to yellow in response to acid production.
