TARAZONA MANRIQUE EMVZ, Luis Edgar et al. Evaluation of physicochemical characteristics of four brands of ultrapasteurized milk in the Cundiboyacense region- Colombia. []. , 14, 3, pp.8-15. ISSN 1900-9607.  https://doi.org/10.21615/cesmvz.14.3.1.

Decree 616 of 2006 determines what should be the physicochemical characteristics that dairy products must contain in Colombia, however, not all times these parameters are followed to the letter, thus affecting the final quality of the product received by the consumer. The objective of this work was to determine the physicochemical characteristics of four brands of UHT milk produced in Boyacá and compare them with national regulations. The physicochemical characteristics of four trademarks of ultrapasteurized milk, produced and consumed in the Cundiboyacense region, Colombia, were evaluated through the MilkoScanTM MARS technique, determining the percentages of protein, fat, lactose, total solids and non-fatty solids, in addition to the point of freezing and comparing it with the current national regulations. An ANOVA was performed between each trademark evaluated and significant differences were found for one of these trademark in comparison with the other three in the variables under study (p <0.05). It was found that none of the trademark complies with the minimum parameters stipulated in the Colombian regulations.
