Detection and cross-linking evaluation of secoiridoid tannins activated with endogenous enzymes

Key Points

• Activation of secoiridoid tannins with endogenous enzymes improves their bioactivity and cross-linking ability.
• A notable increase in cross-linking was observed, indicating enhanced properties of the tannins.
• Cross-linking evaluation involved analyzing the response of phenolic compounds to specific enzymes present.
• This work emphasizes the potential applications of these tannins in health and nutrition, highlighting their functional properties.
