Shelf life testing

Finding out the shelf life of your food product is an important part of getting it ready for market. We provide testing that determines expiration dates, best-by dates, and sell-by dates for a variety of food products. Food samples are conditioned and stored in specific temperatures and humidity conditions, then quality changes are analyzed and evaluated through quality analysis and microbial safety analysis. Expiration dates are determined by food safety and quality criteria. 


Sample Conditioning and Storage 
We provide temperature and humidity chambers for sample conditioning and storage. The clients design their own study and carry out sampling, quality and microbial analysis, as well as sensory evaluation.   

Standard Shelf Life Study 
The product is conditioned and stored at the similar storage temperature and humidity as the distribution environment, and the quality changes of the product are evaluated at a specific sampling duration.

Accelerated Shelf Life Study
The food product is conditioned and stored at elevated temperature and/or humidity and the quality changes of the product are evaluated at a specific sampling rate. The accelerated shelf life study can be two to four times faster than the standard shelf life study.

We're able to carry out full or partial shelf life studies, including experiment design, sampling, quality analysis, microbial analysis, sensory evaluation, data analysis, and study reports.
