Kikkoman has introduced a new hygiene control system based on the luciferase reaction. The system includes LuciPac A3 Surface, LuciPac A3 Water and Lumitester Smart. The latter replaces Lumitester PD-30, which is no longer produced. Lumitester Smart has Bluetooth and can transfer data to your mobile or tablet or via a cable to your PC. There is also a cloud app for storing and presenting the data. LuciPac A3 measures ATP+ADP+AMP, while other luciferase-based hygiene measures only ATP. Enzymes and heat degrade ATP to ADP and AMP. Measuring A3 rather than ATP gives two major advantages:
- The A3, i.e. ATP+ADP+AMP, is stabile while ATP is not (cf. Figure 2 in Bakke and Suzuki). In blood diluted 10x in water all ATP is degraded in 2 hours while A3 is essentially unaffected (cf. Figure 1 in Bakke et al.). This means that one does not have to be concerned when the sample was taken, which you must do when measuring ATP only.
- The signal is for most food & beverages at least 100x higher than ATP. In some cases, as much as 40,557x and only with lettuce as little as 2.8x (Table 2 in Bakke and Suzuki).
The conclusion is that A3 is a more reliable measure on biological contamination. Furthermore, it is much more sensitive (up to 40,557x). Even if A3 and ATP systems at a first glance may seem similar, they are completely different measures on biological contamination. A3 is a premium product compared to ATP and is only produced by Kikkoman Biochemifa.
In some of the attached brochures and on the Kikkoman webpage pictures of the Lumitester PD-30 are shown. As mentioned above this instrument is no longer available as it is replaced by the more advanced Lumitester Smart.
