The mean CIE a*, that indicates the variation between red and green color, is significantly higher (p 6 0.05) in untreated orange juice (4.56 ¡À 0.40) than in the processed juices. The value of this parameter for the HIPEF orange juice is 2.99 ¡À 0.08, and for the pasteurized juice is 1.57 ¡À 0.03, observing significant differences (p 6 0.05) between them. Sa¡änchez-Moreno et al. (2005) describe similar results (decrease of the parameter a*) after pasteurization or high pressure treatment of orange juice. Parameter b*, that indicates the variation between yellow and blue color, is significantly higher (p 6 0.05) in the pasteurized orange juice samples (57.61 ¡À 10.56) than in the HIPEF ones (53.62 ¡À 0.57) and in the untreated orange juice (50.73 ¡À 0.67). These results coincide with the ones described by Lee and Coates (2003) when they study CIE a* and CIE b* in untreated and pasteurized orange juices. These authors obtain that CIE b* values increase with the pasteurization of the juice, whereas CIE a* values decrease. Thus a color shift toward positive b* and negative a* directions indicate more yellow and less red in pasteurized orange juices. CIE a* values decrease significantly (p < 0.05) during the first weeks of refrigerated storage in the juices studied, although they increase again in all ofthem from the sixth week of storage (Table 2). CIE b* decrease significantly (p < 0.05) with the refrigerated storage of the processed juices (Table 2). Rodrigo et al. (2003) describe a significant decrease of the parameter b* when they analyze different pasteurized orange¨Ccarrot juices (77 C, 20 s) stored at 10 C, whereas CIE a* do not present significant variations during the refrigerated storage.
