| Abstract: | ![]()
Cook loss, pH and microstructure of comminuted beef made with four NaCl (1.3, 2.0, 2.6, 3.3%) and two sodium tripolyphosphate levels (0, 0.4%) were evaluated. The addition of phosphate reduced cook loss and raised the pH of the raw product to 6.0. Scanning electron micrographs showed that samples with low cook loss had a fine protein matrix. Phosphate addition helped to reduce cook loss and overcome decreased functionality when using aged meat. |
