Patent 201811547335.X also discloses a method for producing ferric pyrophosphate added into vegetable protein food, which adopts maltodextrin, sodium starch octenyl succinate and calcium phosphate to prepare ferric pyrophosphate into microcapsule powder. Although the problem can be improved to a certain extent by preparing ferric pyrophosphate into microcapsule powder, the technical problems that ferric pyrophosphate microcapsule products are heavy in color, poor in water dispersible solubility and flowability, easy to agglomerate, and short in time and can delay hair-blacking when being applied to Vc series products containing Vc or sodium Vc and the like still exist.
