Pathogenic Amine Detection System (PADS ™)
– Our existing technology demonstrates the ability to create a colorimetric change in the presence of the amine.
Observed color change in DMF in the presence of cadaverine .
Visible color change in PADS ™ can be seen at FDA limits for meat spoilage
- PADS™ that has been exposed to varying amounts of cadaverine.
- The cadaverine solution was added and the mixture was intermittently shaken at room temperature for 10 minutes.
- The concentration of cadaverine in spoiled meat that indicates spoilage is 50 ppm and correlates with bacterial counts .
- The reaction time is nearly instantaneous.
Diagnostic levels of these amines in BV are at levels 10-40 times higher than food spoilage.
