The screening is simple: product samples are treated with a proprietary reagent that reduces non-microbial sources of ‘background’ ATP. Then, a reaction is activated that causes a reaction with any existing microbial ATP, resulting in bioluminescence which can be read by a luminometer or light-recording instrument. When optimized, this allows for rapid screening of sample products quickly and accurately, detecting any potential contamination, allowing the vast majority of production to be released to market rapidly and efficiently.
A great option for rapid microbial screening is The Innovate System which can be used to test a wide variety of product types - from cheese sauce to pulpy juices to thick puddings and even ketchup.
The RapiScreen™ Beverage reagents designed for use with the Innovate System, have strong buffering capacities to neutralize high-acid content in juices and eliminate interference from complex ingredients in dairy formulations. No other rapid method covers such a wide range of products and applications. The Innovate System is flexible and easy to use, even with hard-to-test product types that are:
- Clear, opaque or highly pigmented
- Filterable or non-filterable
- Soluble or non-soluble
- High or low pH
- Preserved or non-preserved
- Aseptically packaged
Here are some of the matrices that have been tested: black tea, coffee concentrate, apple juice, orange juice, prune juice, oat-based juice, almond-based juice, tomato juice, and protein shakes. Below is the range of products and applications that Innovate System can test:
