A kinetic study of post-processing quality loss was conducted. Vitamin C, chlorogenic acid, total polyphenols
and color change were measured during storage study and were used to model the UHPH-treated
apple juice shelf-life. Loss of vitamin C was correlated with the hydroxymethylfurfural (HMF) accumulation
(0.59, P < 0.05). A limiting quality parameter was polyphenolic content. UHPH-treated apple juice
stored at 4 C was found to show a shelf-life for about 21 months by preserving the color characteristics
of the juice with low HMF accumulation. From 15 C changes in quality parameters were more evident.
