Need a Shelf Life?
Not sure what to test for?
Above is a simple calculator that should always be part of the first steps for calculating a shelf life.
There is no point in testing for an organism that simply cannot grow in your food. This calculate uses three parameters – pH, water activity, and storage temperature, to eliminate the need to test for many organisms, or can guide you to formulate into a safe zone where bad bugs cannot grow.
The calculator is above is just one of the tools we use to design a shelf life testing protocol alongside safety validation testing.

Important Things You Should Know
QUESTIONS & ANSWERS
No. For instance, a food might have a pH that is too low for Salmonella to grow in, but it can still survive. A test for salmonella will determine that it is absent – but there is no point testing salmonella over and over again when you know it cannot grow over time.

Testing for Safety
Safety Validation
Safety validation and shelf life testing are not always the same thing, and understanding this important concept is fundamental to designing testing protocols.
We can separate out the safety issues from shelf life issues, and quality issues, and come up with an efficient testing protocol that can be implemented.
