| Abstract | ||||
| This study was applied and aimed at specifying the effect of adding sodium pyrophosphate (SSP salt) to the milk prepared for yogurt manufacturing on pH and the rheological properties of yogurt. This could be occurred by adding (SPP salt) to the full fat reconstituted dried bovine milk before and after heat treatment at 90º C for 10 minutes with rates of 0.05, 0.1, 0.2, 0.3 % respectively. Tests that involved are pH and rheological properties which include viscosity, spontaneous whey separation, percentage of water holding capacity, and hardness directly after manufacturing and during storage at (1± 5)º C for 14 days. Results have shown that yogurt treatments with the addition of SPP salt before heat-treatment had increased pH value compared to the control and also have an applicable rheological property within extended ratios( 0.05, 0.1 and 0.2 % )compared with the same properties for addition treatments after the heat treatment. | ||||
