MOSH/MOAH in a food product may result from unintentional contamination occurring at various levels of the supply chain or migration from packaging. This preliminary research aims to evaluate the differences and variations in contamination levels between raw and processed milk samples to assess the contamination risk associated with milk processing. Using LC-GC-FID, mineral oil hydrocarbons (MOSH; MOAH) were quantified in eight milk samples. A Ttest was applied to evaluate the differences in the distribution of carbonic sub-fractions and total levels of MOSH and MOAH contamination (n-C10-50) in experimental samples of unprocessed milk and lyophilized milk. All statistical analyzes were performed using SPSS Statistics 26.0 and GraphPad Prism 9 software packages. The results of the comparative analysis revealed that milk processing operations had a significant impact on the variation of the MOH contamination level in the freeze-dried milk. MOSH and MOAH content varied significantly between initial samples (0.8-8.7 mg/kg MOSH; 0-2.8 mg/kg MOAH) and final samples (4.5-13.1 mg/kg MOSH; 3.2-5.35 mg/kg MOAH). These results are relevant for evaluating the impact of the freeze-drying process on these contaminants. [ABSTRACT FROM AUTHOR] |
