Shelf life, Sterility, Preservative efficacy

Food products must meet national and international food hygiene regulations relating to shelf life. This helps to keep consumers safe and your organization compliant, which both contribute to manufacturing your brands integrity and reputation, we can assess the quality of your products to ensure they do so. METS Lab works with each product throughout US shelf life, with procedure including microbial indicator analysis as well as sensory, physical and chemical testing. Our shelf-life testing services helps you recognize how your food products performs over time and identify the changes to ingredients, packaging or to other contributory factors that will help lengthen shelf life and increase profit. 

We have chemicals testing labs or food testing labs around the world with the appropriate accreditation, making the process as reliable, efficient, and cost effective as possible for you. All tests are executed by qualified, on-site food scientists that perform analyses under a rigorous quality control program

METS Lab has identified many factors that affect the shelf life and ultimately, food product, quality. To discover how your business can benefit from our shelf life testing services, contact us today


Sterilization is the complete destruction or elimination of all viable organism in/on object being sterilized. The process destroys yeast, vegetative bacteria and spore formers, and allows the food processor to store and distribute the products at ambient temperature. Thus, extending the shelf life. 

A products initial microbial load will greatly impact the shelf life. The microbial load is especially pertinent for perishable items. Like we all know preservative can be added to extend shelf life, as can antioxidants. Preservative efficiency test is important parameter for both pharmaceutical and food products where there is higher risk of microbial contamination. 

Preservative efficiency:

The preservative efficiency test is a laboratory tests that determines the level of antimicrobial activity of a product and evaluate how well a product with stands microbial contamination during use. This testing provides two main benefits

Firstly, it evaluates the product to see what maximum quantity of preservative they should have

Secondly, it evaluates the product to see whether or not they are within the preservative described limits and for preservative effectiveness testing.
