Product and Packaging Stability Testing
Keeping food products safe for consumers and optimizing shelf life can be as important as the product itself. When determining what tests need to be done, the researcher must take many things into consideration. These include the mode of transportation for the product and the climate where the product is utilized, in addition to the industry standard for shelf life on the product itself. Once the environmental conditions that the product may experience have been determined, that climate needs to be reproduced in a controlled environment.
Having a chamber that is larger than needed with wide temperature and humidity ranges is a common problem that can be avoided. The steps toward determining the most efficient chamber include defining the duration of the test, specific test protocols, and the size and quantity of the samples being tested. Defining the duration of a specific test is extremely important. While each product is unique, stability testing can usually be narrowed down to two extreme conditions, and then samples are tested for an extended time period. Because of the longevity of these procedures, the most efficient chambers are designed for specific parameters. Using specific temperature and humidity parameters when choosing an environmental chamber will ensure that the system operates under optimum conditions, thereby improving the overall life of the components. In addition, the chamber's temperature and humidity performance is greatly improved over a chamber with a wide range of parameters.
