. Phytic acid can form insoluble compounds with calcium, iron, magnesium, zinc and other metal ions, reducing the effectiveness of metal ions. Phytate can also form complexes with proteins, making metal Ions are even less utilized. Phytic acid is commonly found in plant-source foods and is the main anti-nutritional component that affects the absorption of mineral elements.
. Because of its high content in plant-source foods, uncombined phytic acid also binds to endogenous zinc, copper and other elements that are secreted and excreted into the small intestine by various organs such as pancreatic juice and bile. It can be seen that phytic acid not only affects the utilization of trace elements in food sources, but also hinders the reabsorption of endogenous trace elements.
. Phytic acid is a strong acid with strong chelating ability. Its
negatively charged phosphate group, in addition to combining with metal cations, can also effectively cooperate with protein molecules. , thereby reducing the digestibility of protein by animals. However, when the value is lower than the isoelectric point of the protein, the protein is positively charged. Due to the strong electrostatic interaction, it is easy to form an insoluble complex with the negatively charged phytic acid. The positively charged groups on the protein are likely to rely on When the amino group of the amino acid, arginine and the guanidine group of histidine are higher than the isoelectric point of the protein, the free carboxyl group of the protein and the unprotonated imidazole group on histidine are negatively charged. At this time, the protein uses multivalent cations as bridges to form a ternary complex with phytic acid. The ternary complex formed by phytic acid, metal ions and protein not only has very low solubility, but also has a greatly reduced digestion and utilization rate
