Food Scanner

The F-750 Food Scanner for fruit quality measurement analyses the product quality of plant foods through near-infrared spectral analysis (NIRS) in a quick and non-destructive way.

This measuring method is already used in many industrial applications for material testing and is also suitable for swift deployment of the various stages of the plant value chain. In many experiments, e.g. for tomatoes, grapes, mangoes and blueberries, a very good correlation has been stated between e.g. the Brix value (sugar content) and the NIRS value.

The correlation to other quality parameters required for predictive models, for example, like dry matter content, acidity or hardness, must be determined by tests.

Product Features:

  • Measures traits including:
    Total Soluble Solids (TSS or brix)
    Dry Matter
    Titratable Acidity
    Internal Color
    External Color
  • Light-weight, portable, and field-ready
  • Fast and consistent—scans take 4-6 seconds per sample
  • Non-destructive measurements
  • Built-in GPS for easy crop mapping
  • Transflective display for outdoor viewing
  • Rechargeable/replaceable batteries that last all day
  • Wi-Fi capabilities

F-750 allows creating of own models and its adapting for the respective field of application. The non-destructive prediction of the current ripeness degree and the estimated shelf life can help to prevent future food losses in the fruit and vegetables business, since alternative methods of utilization can be taken early in case of insufficient quality.
