The hygienic and safe packing of food products is often challenging. This process step largely determines the quality and shelf-life of the final product. Foods that are fresh or foods that easily spoil such as milk and dairy products must be packaged under sterile or near-sterile conditions. In order to achieve this, the packaging is sterilized just before being filled with the products. Industry uses a variety of machine concepts and sterilization methods for this based on chemical or physical technologies. These must have precise and reproducible effects.
We perform microbiological validations in the form of challenge tests. These measure the effectiveness of your sterilization systems and filling plants. Using defined methods such as artificially contaminated foods and packaging materials, we identify possible weak spots in your filling process and evaluate the overall effectiveness of your sterilization system. Based on the results we give you advice about process optimization and plant design. Simultaneously we offer validation of microbiological efficiency in accordance with VDMA recommendations and technical bulletins.
