Studies of the effect of ethylene diamine tetraacetic acid (EDTA) on sorbic acid degradation
The effect of ethylene diamine tetraacetic acid (EDTA) on sorbic acid degradation and the resultant browning was studied at 33, 45 and 57°C in model aqueous systems with pH 5.0 and a water activity of 0.91. The EDTA enhanced sorbate degradation probably as a result of iron scavenging from the packag...
