In the present study, regardless of the phosphate incorporated
or degree of encapsulation, phosphates resulted in lower (p b 0.05)
TBARS values in comparison to the control samples on all days of 7 day storage period in cooked beef and chicken samples (p b 0.05). Molins et al. (1985) found an increase in orthophosphate concentration due to heat-induced hydrolysis of STP and SPP from cooking. An increase in orthophosphate can reduce the activity of phosphatase enzymes,hence, reducing oxidation (Sofos, 1986). Phosphates also reduce the phosphatase activity by sequestering metals needed to enhance enzymatic activity (McComb et al., 1979).
