Proteomic, Fatty Acid and Mineral Profiles of PDO Arouquesa and Commercial Crossbred Beefs: A Tool for Certification.

ABSTRACT: Protected Designation of Origin (PDO) beef products are recognized for their higher quality, although the native breeds used often show lower productivity compared to commercial crosses. This study aimed to compare the proteome profiles of Arouquesa and crossbred beef using 2D-DIGE, and evaluating crude protein, energy, and fatty acid composition. Arouquesa beef had higher energy values (p < 0.05), whereas crossbred samples showed greater protein content (p < 0.05). Moreover, Arouquesa beef had higher proportions of microminerals, namely zinc, iron, and manganese (p < 0.05). The Arouquesa breed also presented higher proportions of most fatty acids, including saturated, monounsaturated, and polyunsaturated. Proteomic analysis identified 34 differentially abundant proteo
