Guerrero-Beltran et al. (2009) reported that long UV treatment increases the total color difference (DE) in grape and cranberry juices because of the loss of red–purple anthocyanin pigments of juices. However, Pala et al. (2011) reported that the total anthocyanin content of pomegranate juice does not significantly change after UV-C treatment. Our study proved that the direct exposure to sunlight might seriously deteriorate SJ color and significantly shorten shelf life. Therefore, packaging isolated light and storing in a dark place are important for keeping the stability of SJ color.
