Enzymatic
browning, catalyzed by polyphenol oxidase and peroxidase,
also caused changes in the natural color of sugarcane juice
(Qudsieh et al.2002;Romeroetal.2001; Yusof et al. 2000).
As HPP is conducted at room temperature, it does not result in
the development of Maillard reaction or undesirable flavor, or
nutrient destruction. Presumably, associated color changes in
sugarcane juice were due to enzymatic browning reactions,
caused by polyphenol oxidase or peroxidase (Krebbers et al.
2003).
