B.I.Stepanov Institute of Physics of the National Academy of Sciences of Belarus offers consumers services for the identification and determination of physico-chemical characteristics of food products using multiparametric analysis of optical spectra under an outsourcing agreement.

B.I.Stepanov Institute of Physics of the National Academy of Sciences of Belarus provides services for the identification and determination of physico-chemical characteristics of industrially manufactured food products using optical spectroscopy of UV, visible and near-infrared ranges and developed multiparametric data processing methods.

Pilot projects have been carried out on the characteristics of vodkas, wines and vegetable oils. In the study of 153 varieties of vodka products, the possibility of solving the problem of 100% detection of counterfeit by multiparametric analysis of transmission spectra measured in the UV and visible ranges was shown.
