The objective of this work was to analyze the raw milk composition readings obtained by FTIR spectroscopy, and somatic cells count and total bacterial count by flow cytometry after starch and sucrose addition. In some countries, these substances are illegally added to increase milk density after fraudulent addition of water. The raw milk was adulterated with 3 concentrations of starch and sucrose (0.1, 0.5, and 1%) in vials containing bronopol or azidiol, and stored at 2 temperatures (7 ± 2°C and 25 ± 2°C). The analyses were performed after 0, 3, 24, 48, 72, and 168 h of storage. Multiple linear regression model was used for statistical analysis. The addition of starch and sucrose resulted in a significant change (P < 0.05) for all dependent variables. Starch resulted in an increase in the IR results for fat, protein, lactose, total solids (TS), solids nonfat (SNF), SCC and TBC and decrease in casein, milk urea nitrogen (MUN) and freezing point. The addition of sucrose led to increased IR results for lactose, TS, SNG and MUN, while protein, casein, freezing point and SCC decreased. This work provides evidence to the importance of adulterants monitoring in milk, since they affect the analytical results of milk quality, obtained by electronic methods.
