The effect of ionic-molecular composition of reconstituted milk solutions on the response of potentiometric ion-selective electrodes and cross sensitive Donnan-potential sensors based on MF-4SC membranes in H- and K-forms has been studied. The multivariate data were processed and interpreted using the radar chart and principle component analysis. The multisensory system based on membrane sensors with a software and hardware complex for recognition of the reconstituted milk samples containing from 0.40 to 8.46 wt % of dried milk has been developed.
