Enzyme aided extraction has been reported to have both adverse and favourable effects on bioactive compounds. Increases in antioxidant activity by enzyme aided extraction have been reported by many studies, mostly in plants (Li et al., 2006). The increase in the release of polyphenols by the enzyme preparations suggests that these enzymes may contain activities that directly promote selective release of antioxidant phenols or modify released phenols to more potent antioxidant compounds. Aside from the favourable effects of enzyme aided extraction on bioactive compounds, there was a decrease in the anthocyanin content in fruit juice (Chaovanalikit et al., 2012).
