Resumo

Cheese whey is a nutritious byproduct in the dairy industry, however, due to low commercial value, its use as a milk adulterant is a common practice not easily detected by routine analysis. In Brazil, quantification of caseinomacropeptide (CMP) index, using High Performance Liquid Chromatography (HPLC), is officially used to investigate illegal cheese whey addition to milk. Milk with CMP index above 30mg/L is considered not suitable for human consumption. The objective of this research was to report the CMP index in 185 samples of pasteurized milk, representing 73 commercial brands produced in 51 counties and ten mesoregions of the state of Minas Gerais, from 2011 to 2013 (58 samples) and 2015 to 2017 (127 samples). CMP index was considered normal (up to 30mg/L) in 75.1% of the samples. However, 21.1% presented CMP index above 75mg/L and 3.8% from 31 to 75mg/L. CMP index above 75mg/L was found in 17.4% of the samples produced during the dry season (April to September) and in 24.7% during the rainy season (October to March). These data point to the need of more efficient monitoring and inspection processes to hinder adulteration with cheese whey addition to milk.(AU)
