Food & Beverage

A cooperation with the market leader for beverage filling systems, Krones AG, Neutraubling, triggered our Food & Beverage business field in the late 1990’s. PreSens supplies sensors for checking the air-tightness of packaging and a special systems for determining the oxygen ingress in PET bottles at companies such as Nestle, Heineken or Danisco. Reliable results can be obtained in an easy, time-saving way and can help to ensure the filling quality and long-term storage stability of your products.

Packaging Development: Contactless & non-destructive determination of oxygen ingress in food packaging

Oxygen inside packaging can lead to oxidative deterioration of foods or beverages. The amount of tolerable oxygen inside packaging can differ greatly according to the packed product. PreSens oxygen sensors help finding the right packaging material for your product. Materials with different oxygen permeability or the tightness of closures can easily be determined in contactless measurements with oxygen sensor spots. Even smallest oxygen traces can be detected.

Material Research: Oxygen transmission rate of synthetic materials

In cooperation with the Fraunhofer Institute for Process Engineering and Packaging in Freising, Germany, PreSens has developed an extremely leak tight measurement cell for testing different material films. An oxygen meter and sensors with a measurement range from 1 ppb to 100 % oxygen allow investigating perforated or high-barrier materials on their oxygen transmission rate. Even the effect of different coatings on the oxygen barrier properties can be analyzed with this easy-to-handle measurement tool.

Quality Control: Oxygen determination in headspace & the product

Unwanted oxygen taken up during production or the filling process can shorten the shelf life of certain products. PreSens offers several sensor solutions for measurements in the final product under real conditions. The oxygen content in the headspace of packages as well as in the product itself can easily be determined in micro-invasive or even contactless measurements. This way the quality of the final packed or bottled product and a long shelf life can be assured.

In-Process Control: Fast assessment of oxygen levels during production

PreSens offers engineering services, to provide sensor solutions for in-process measurements, according to your needs. Several specially designed measurement systems for breweries are already available. Flow-through cells with integrated sensors that can be installed in steel pipes, or robust probes for in-line measurement that stand CIP, SIP and autoclaving are combined with portable oxygen meters and allow easy checks at different stages of production.
