Effect of Goat and Cow Milk Ratios on the Physicochemical,Rheological, and Sensory Properties of a Fresh Panela Cheese

Fresh cheeses, Panela type, were manufactured from cow milk and with goat milk incorporation, constituting 4 blends of milks (G10:C90, G20:C80, G30:C70, G40:C60, v/v). The cheeses were analyzed to determine the effect of the different goat milk ratios on the physicochemical, textural, rheological, and sensory properties over 15 d of storage. Significant differences in protein (14.6% to 18.5%), fat (13.0% to 19.4%), and moisture contents (51.7% to 61.3%), pH (6.38 to 6.67), color (L_h > 64.4, a_h > 1.06, b_h > 5.14), textural (σ_f > 14.8 kPa, ε_C: 0.77 to 0.79, elasticity modulus > 13.5 kPa), and rheological parameters (G′ > G′′, G′: 10.6 to 31.9 kPa, G′′: 2.39 to 7.31 kPa, tan δ: 0.21 to 0.24) were detected as a function of the milks ratio, as well as a function of the storage time. The incorporation of goat milk improved the overall quality in the formulation of Panela cheese, enhancing the texture, flavor and aroma, commonly associated with hand‐crafted cheeses when they are used in the proper ratio. Furthermore, the nutritional value of the cheese is increased with the incorporation of goat milk, which can contribute to a better consumer health.
