A new rapid yeast and mold test method for dairy applications, such as yogurt, soft cheese and cream, is said to dramatically improve speed-to-market and reduce economic impact from spoiled product.
GreenLight detection platform from MOCON, Inc., Minneapolis, is said to reduce testing times by up to 80%, enabling dairies to release product in approximately 18 hours with confidence that it does not contain yeast/mold spoilage organisms.
The rapid testing capability can also serve as an early warning that there is an issue with either the packaging line or the package structure itself. For example, if a yogurt container hasn’t been correctly sealed, it can create a hospitable environment for mold growth.
GreenLight achieves results for yeast and mold using the same automated reader and unique APCheck oxygen sensing vials as for bacteria. The user simply adds a commercially available selective media to the vial. The GreenLight system can then be loaded with mixtures of bacterial and other tests at the same time and controlled automatically.
The GreenLight system is configured to provide quantitative on-screen data and pass/fail testing in a fully automated mode.
