ACETOLINE is a worldwide unique NIR system capable of measuring acetic acid and alcohol concentration simultaneously and reliably in vinegar production. The new device significantly simplifies the routine analysis in the production of vinegar. In only one step, on-line during the production process, the alcohol and acetic acid concentration of your vinegar sample is determined precisely and fast. Consequently, the production process is monitored closely, as the two most important production parameters can be easily determined automatically.

ACETOLINE is based on NIR spectroscopy. Almost every substance has a spectral “fingerprint” which is generated by the adsorption of the penetrating light and thereby weakened in a characteristic way. These fingerprints can be used to identify substances and to quantify the concentration in a mixture of substances without any cross-sensitivity. The penetrating light impinges on a sensor array and is evaluated on the basis of neural networks.
