Abstract(s)
Milk adulteration presents substantial challenges in
the food industry, prompting the need for efficient de-
tection methods. This study introduces a potentiometric
electronic tongue for rapid and accurate detection of milk
adulteration. Using polymeric membranes with various
integrated additives, the electronic tongue distinguished
between different milk types and detected common adul-
terants. Experimental results demonstrated its effective-
ness in discriminating raw, pasteurized, and medicated
cow milk, as well as goat milk. Moreover, it success-
fully identified adulterants, such as water and cow milk,
in goat milk samples. Chemometric analyses, including
principal component analysis and partial least squares
regression, correlated sensor responses with traditional
milk parameters such as fat, protein, and lactose content
with an R 2 of up to 0.97 on the validation step. Strong
correlations validated the electronic tongue’s potential
for rapid milk quality assessment. This innovative ap-
proach offers a cost-effective, reliable solution for de-
tecting milk adulteration in contrast to current techniques
that require numerous time-consuming experiments.
