In the present study short PL
exposure times (2 or 4 s) caused no changes in the measured
quality attributes of apple juice. In a study performed by Kasahara
et al. (2004) on clarified apple juice, exposure to pulsed UV light at
different energy dosages (from 1850 to 3354 mJ/cm2) did not cause
significant differences from the control sample in terms of soluble
solids, turbidity, acidity, viscosity and colour. However instrumental
colour measurement also performed in the present study,
revealed a slightly noticeable (0.5 < DE
