Unlocking native xanthan gum via succinylation to construct a hydrophilicity-driven O/W emulsion gel for enhanced luteolin delivery and pH-responsive release.
Succinylated xanthan gum (SA-XG) was developed to overcome native XG's poor emulsion-stabilizing capacity caused by inherent high hydrophilicity, yielding a biocompatible emulsion stabilizer for food, cosmetic, and pharmaceutical applications. Under optimized conditions (SA-XG degree of substitution (DS) 0.03, 0.5% w/v...
