Means ± standard deviation. Different letters (a, b, c, d, e, and f) in the rows indicate significant differences for each parameter (). Sample denomination: control samples (samples C)—only air packaged fresh veal; the experimental samples: samples D—air packaged veal treated with 0.02% dihydroquercetin solution; samples MAP—modified atmosphere (80%O₂/20%CO₂) packaged veal only; samples BMAP—modified atmosphere (80%O₂/20%CO₂) packaged veal treated with 0.02% butylated hydroxytoluene solution; and samples DMAP—modified atmosphere (80%O₂/20%CO₂) packaged veal treated with 0.02% dihydroquercetin solution.
