Methods to characterize the structure of food powders a review
Food powders can exist in amorphous, crystalline or mixed structure depending on the order of molecular arrangement in the powder particle matrices In food production, the structure of powders has a greatly effect on their stability, functionality, and applicability The undesirable structure of powders can be accidentally formed duringSince the surface of talc powder has a large number of MgO and OH bonds, when talcum powder is in full contact with heavy metal ions in water or soil, the heavy metal ions will cooperate with MgO and OH to immobilize heavy metal ions on the surface of talc powder, thereby realizing the separation of heavy metal ions from water or soil0HWDO 3DVVLYDWLRQ$JHQW IOPscience
