And both a* values of fermented heat- and high hydrostatic pressure - treated litchi juice were kept at a low negative value during 4 weeks of storage at 4 °C (Table 4), indicating that the characteristic color of the litchi juice (white)was maintained throughout the storage. Moreover, the fermentation of L. casei had no significant effect (p N 0.05) to both a* values of heat- and HHP-treated litchi juice (Table 4).
