Orange juice is highly valued by consumers for its nutritional content,
appealing colour and refreshing sweet and sour taste. Among
different processing technologies, heat pasteurisation is the most
common technique to extend the shelf-life of orange juice. The
inactivation of spoilage microorganisms and thermally resistant
endogenous enzymes (e.g., pectin methylesterase (PME)) can be
achieved under temperature conditions at 90–98 C for 10–60 s
