Ascorbic acid (AA) is an important vitamin in fruits and vegetables and
is also widely used as an antioxidant for preventing enzymatic browning
in fruit processing (Lee & Kader, 2000). The loss of ascorbic acid in pressure treated samples varied between 3 and 27% (Fig. 1). It has been observed that, 95 and 96% of ascorbic acid has been retained at 600 MPa/
30 °C/20 min and 400 MPa/30 °C/20 min, respectively. This supports the
fact that, high pressure has very little effect on ascorbic acid content in
the mixed fruit beverage (Plaza et al., 2006). At 500 MPa, 95 and 80%
