Abstract
A method for spectroscopically determining the concentration of alcohols with 1 to 5 carbon atoms, especially ethanol, in liquid probes, especially alcohol-containing food products, healing preparations, cosmetic products and the like. The absorption of light by the probe is measured at at least one wave length in the range of 1100 nm to 1300 nm, and preferably in the range of 1150 nm to 1250 nm. The alcohol concentration is determined from the measured absorption with the help of a calibration. The alcohol content of a liquid probe can be determined in a simple and fast manner and over a large concentration range.
