No significant change (p N 0.05) in the content of ascorbic acid was observed in heat-treated litchi juice as fermented for 18 h by L. casei at 30 °C, whereas the content of ascorbic acid in high hydrostatic pressure-treated litchi juice increased to 246.9 mg/L as fermented for 18 h by L. casei at 30 °C (Fig. 3),which may be attributed to the deoxidation of oxidized ascorbic acid of high hydrostatic pressure - treated litchi juice by L. casei (Jagannath, Raju, & Bawa, 2012).
