Pasteurization is important to the stability of citrus juice during transportation and marketing. Increased consumer demand for fresh-like products with minimal vitamin and flavour losses stimulated the search for new mild preservation techniques (Mertens & Knorr, 1992). The development of alternatives to heat processing is also motivated by the real need for environmental friendly technologies. High Intensity Pulsed Electric Field (HIPEF), one of the nonthermal minimal processing technologies that stand in the interest of scientists and food industry as a new, alternative (preservation) process for liquid food, meets these criteria (Butz & Tauscher, 2002; Elez-Martı¡änez, Escola¡ä - Herna¡ändez, Soliva-Fortuny, & Martı¡än-Belloso, 2005; Shivashankara, Isobe, Al-Haq, Takenaka, & Shiina, 2004; Spilimbergo, Dehghani, Bertucco, & Foster, 2003; Torregrosa, Corte¡äs, Esteve, & Frı¡ägola, 2005; Torregrosa, Esteve, Frı¡ägola, & Corte¡äs, 2005). A number of authors have studied the evolution of quality factors in orange juice after HIPEF treatment in some cases making a comparison with the evolution after heat treatment (Ayhan et al., 2001; Cserhalmi, Sass-Kiss, To¡äth-Markus, & Lechner, 2006; Yeom, Streaker, Zhang, & Min, 2000). HIPEF technology needs further evaluation, because there is not enough information about the evolution of physical and chemical properties of fruit juices during refrigerated storage as long-term effects of the HIPEF treatments on orange juice have not been reported. The aim of this study was to evaluate the effect on color, browning and HMF of an orange juice treated by HIPEF and the same juice pasteurized, during seven weeks stored in refrigeration at 2 C and 10 C in order to determine if the application of HIPEF can lead to longer shelf life of fruit juices with minimal product quality loss and good retention of fresh-like flavour. |
