Table 1:
Compositional parameters of cottage cheese (TSS (%), Acidity (%), Fat (%), Lactose (%), Moisture (%), Protein (%), and Ash (%)) determined for blends of cow and goat milk at varying concentrations: CG1 (100:0), CG2 (90:10), CG3 (80:20), CG4 (70:30), CG5 (60:40), CG6 (50:50), and CG7 (0:100).
Table 2:
Coagulation time (sec) and Cheese yield (%) for cottage cheese made from blends of cow and goat milk at varying concentrations: CG1 (100:0), CG2 (90:10), CG3 (80:20), CG4 (70:30), CG5 (60:40), CG6 (50:50), and CG7 (0:100).
Figure 1:
Effect of cow and goat milk blend in different concentrations CG1 (100:0), CG2 (90:10), CG3 (80:20), CG4 (70:30), CG5 (60:40), CG6 (50:50), CG7 (0:100) on (A) Protein content, (B) Fat content, (C) Ash content, and (D) Moisture content of cottage cheese during 15 days storage at 5±1oC. Vertical bars represent standard error of means for three replicates. Different letters show significant difference among mean values using LSD at (P ≤ 0.05).
