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
Shelf life is determined by assessing factors such as pH, water activity, ingredients, processing, and storage conditions. In many cases, a structured assessment can identify what testing is actually required before committing to laboratory work.
The required tests depend on the product. These may include microbiological testing, water activity testing, pH measurement, or storage trials. Many products require fewer tests than initially expected.
Costs vary depending on the type and number of tests required. A targeted approach can significantly reduce costs compared to broad, unnecessary testing.
Frozen products are generally lower risk from a microbial growth perspective, but shelf life still needs to be validated for quality and stability over time.
Not always. Some products can be assessed using known scientific principles and product characteristics. However, higher-risk products may require laboratory testing to confirm safety and stability.

Accelerated testing can be useful in some cases, but it must be applied carefully. Results can differ from real-time storage, so it is not always suitable for every product.
pH measures the acidity of a product. Lower pH levels can inhibit microbial growth and extend shelf life, making it a key factor in many shelf life assessments.
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.
