Shelf Life Testing

As a producer of food, you must have a substantiation for the shelf life of the products you sell. It is therefore important to know how long your product can be kept. To determine the shelf life, we conduct a shelf life study. We will then examine your product for microbiological and organoleptic parameters. Based on the results, we will give you advice about the shelf life of the product under investigation. Would you rather know if it is possible to extend the shelf life? We can also give you advice on that.

Shelf Life Testing in short

  • Substantiate the shelf life of your food
  • Comply with the legal requirements
  • Perform a challenge test or predictive microbiology

Why research shelf life?

It is required by law to indicate a best-before date on prepackaged foods. The expiry date gives consumers the assurance that up to that date, the product has its normal quality properties (normal colour, odour, consistency and taste), is not spoiled and is not a health hazard. A shelf life study gives you all this information, so that you can offer a qualitatively safe and good product to the consumer.

Less packaging materials

Currently, there is a focus on reducing packaging materials in the supermarket chain, as packaging materials are a burden on the environment. In recent years, there has been an increasing interest in selling products without packaging material.

However, removing packaging material from the equation should never negatively impact the shelf life of a product. If that happens, there is a risk that the environmental benefits will be offset by an increase in product waste in supermarkets or at the consumers’ homes.

Various studies to test the shelf life

A shelf life study can focus on safety (for example Listeria monocytogenes), and on the spoilage of a food (for example, total bacterial count). Different types of research are therefore possible:

  • A challenge test

In a challenge test, we will contaminate your product with a known concentration of a micro-organism. We will then monitor its growth during the shelf life of the product.

  • Predictive microbiology

This is the application of predictive models in which we calculate, among other things, the potential growth rate of micro-organisms. In this modeling, we include various product and process parameters to estimate shelf life.

  • Effects of different variables

An investigation of the effect of various variables such as temperature to control the behaviour of the product. It is also possible to compare various process techniques.
