Functionalization of sodium carboxymethylated yeast β‐glucan by epigallocatechin gallate: Antioxidant activity and color stability

Sodium carboxymethylated yeast β‐glucan (SC‐GLUCAN) was functionalized with epigallocatechin gallate (EGCG) by esterification. EGCG was first succinylized and then grafted onto SC‐GLUCAN through an N, N′ carbonyldiimidazole mediated reaction. The graft of EGCG with SC‐GLUCAN (SC‐GLUCAN‐g‐EGCG) was v...
