Values between 0 and 7 indicate acidity and values between 7 and 14 indicate alkalinity.
The value for pure distilled water is 7, which is considered neutral.
Table A. Interaction of PH and AW for control of spores in FOOD heat-treated to destroy vegetative cells and subsequently PACKAGED
AW values | PH: 4.6 or less | PH: > 4.6 - 5.6 | PH: > 5.6 |
<0.92 | non-TCS FOOD* | non-TCS FOOD | non-TCS FOOD |
> 0.92 - 0.95 | non-TCS FOOD | non-TCS FOOD | PA** |
> 0.95 | non-TCS FOOD | PA | PA |
* TCS FOOD means TIME/TEMPERATURE CONTROL FOR SAFETY FOOD
** PA means Product Assessment required
