8-Hydroxygenistein (8-OHG) is an antioxidant that can effectively scavenge nitric oxide (NO) and superoxide anion (O??). 8-Hydroxygenistein belongs to ortho-dihydroxy isoflavones (ODI) and is abundantly present in dark soy sauce and light soy sauce. Its antioxidant activity is stronger than that of its parent compound genistein. The content of 8-Hydroxygenistein is positively correlated with the antioxidant capacity of soy sauce (r = 0.959), and it remains highly stable even after being heated in boiling water for 60 minutes. During the brewing and storage of soy sauce, 8-Hydroxygenistein effectively prevents oxidative damage, making it promising for use in food antioxidant research.

Amylopectin is a highly branched polysaccharide based on glucose. It forms starch together with amylose. The glycosidic bond of amylopectin is α- Glucan chain α- 1, 4 and branching points α- 1，6。
