This paper suggests that for water added in raw milk has been developed using Interdigital capacitor electrical conductance measurements, other than using conventional methods such as determination of specific gravity or of the freezing point temperature, and the compression on frozen samples. The system has been assembled and the experiments were conducted. The characteristics at 1 KHz, 10 KHz and 20±1 ℃ for all raw milk samples revealed a linear increase in conductance with increasing water content over the entire of water concentrations. Results shown that the capacitance value of the water added in raw milk were lower than the raw milk without added water. It also provides an opportunity for the development of a microcontroller-base low-cost sensing system.

PL

Do badan ia zawartości wody w mleku wykorzystano czujnik pojemnościowy. Badania przy różnych częstotliwościach wykazały że między przewodnością i dodatkiem wody jest liniowa zależność. Także między pojemnością a koncentracją mleka obowiązuje zależność liniowa.

Słowa kluczowe
