Abstract.
In this work, chemometric methods are reported as potential tools for
monitoring the authenticity of Brazilian ultra-high temperature (UHT)
milk processed in industrial plants located in different regions of the
country. A total of 100 samples were submitted to the qualitative
analysis of adulterants such as starch, chlorine, formol, hydrogen
peroxide and urine. Except for starch, all the samples reported, at
least, the presence of one adulterant. The use of chemometric
methodologies such as the Principal Component Analysis (PCA) and
Hierarchical Cluster Analysis (HCA) enabled the verification of the
occurrence of certain adulterations in specific regions. The proposed
multivariate approaches may allow the sanitary agency authorities to
optimise materials, human and financial resources, as they associate
the occurrence of adulterations to the geographical location of the
industrial plants.
