Physicochemical properties of Butter cheese from Marajó manufactured with buffalo milk and cow milk

This study aimed to evaluate the physicochemical characteristics, texture and color parameters of the artisanal Butter cheese from Marajó, manufactured with partial substitution of buffalo milk for cow milk.Four formulations were elaborated: B 100 (100% buffalo milk); B 80 (80% buffalo milk + 20% cow milk); B 70 (70% buffalo milk + 30% cow milk) and B 60 (60% buffalo milk + 40% cow milk).Three replicates were performed.The partial substitution of 20%, 30% and 40% of buffalo milk caused the reduction of fat in 16.2%, 21.6% and 25.4%, and protein in 5.2%, 5.7%, and 6%, respectively, with decrease of elasticity, cohesiveness, gumminess and chewiness, but had no influence on the hardness.Moisture had significant and strongly negative correlation with elasticity, cohesiveness, gumminess and chewiness.Fat and protein had significant and strongly positive correlations with elasticity, cohesiveness, gumminess and chewiness.Significant differences were found for color variables L*, a*, b* and h o .The increase in cow milk concentration increased the yellowgreenish tonality, with an emphasis in yellow tones.
