Food safety and cereal quality

Food safety is currently a demand of today's consumers as well as an imperative to open new markets. From the laboratory services of PCTAD we can help you to comply these requirements and carry out shelf life studies which are of great use in food and agricultural products. Moreover, this laboratory has the necessary equipment to carry out the cereal-specific quality analysis.

    • Food safety (biological contaminants)
    • Different customised analytical techniques at the customer's request.
  • Shelf–life of food
    •  Validation of food preservation and hygienisation methods.
    • Studies of the self-life of food
