  • Shelf-Life Studies

    As defined by the UK Institute of Food Science and Technology, shelf-life represents the period of time during which the food product will remain, safe; retain its desired sensory, chemical, physical, microbiological and functional characteristics.

    PBR offers microbiological shelf-life testing with all applicable tests including challenge testing. In addition, PBR works closely with customers in planning the shelf-life studies of their products. Generally, the factors considered are: desired shelf-life durations; short (up to one week), medium (up to three weeks) or long (up to one year); safety considerations; storage conditions; and controlled conditions that mimic those the product is likely to encounter during storage.

    PBR offers routine Real Time Shelf Life (RSL) as well as, where applicable, accelerated shelf life (ASL) testing for longer shelf-life products. Some selected tests are listed in the table below.
