The evolution of red color loss in the pasteurized pomegranate juice samples during storage is shown in Fig. 1. Just after heat treatments, the measuring of A520 indicated that in clarified juice (Fig. 1A) the loss of red color due to the LTP treatment was 3% while that produced by HTP treatment reached values of 22%. However, in cloudy juice (Fig. 1B) the loss of red color due to pasteurization treatments was similar in both conditions reaching values of 42%.
