This invention relates to the field of biomedical technology, providing a phosphorylated peptide iron chelate of Yanbian cattle hemoglobin, its preparation method, and its applications. The Yanbian cattle hemoglobin phosphorylated peptide iron chelate is prepared from Yanbian cattle blood through enzymatic hydrolysis, phosphorylation, and iron chelation. Specifically, the phosphorylation step actively introduces strongly negatively charged phosphate groups into the Yanbian cattle hemoglobin peptide chain, serving as new and stronger metal ion coordination sites, thereby specifically enhancing its chelating ability for ferrous ions and the stability of the complex. The Yanbian cattle hemoglobin phosphorylated peptide iron chelate possesses high iron content and good gastrointestinal stability, showing broad application prospects in the preparation of a new generation of highly efficient and low-irritant iron supplements.

The application relates to the technical field of sialic acid application, in particular to application of sialic acid in promoting iron absorption of iron supplement agents. It is found for the first time that sialic acid with a daily intake of 0.8-3.5 mg / kg and ferrous iron with a daily intake of 0.2-0.5 mg / kg can promote the absorption of ferrous iron by human bodies. More specifically, the application claims an iron supplement agent containing ferrous iron drugs and sialic acid. The iron supplement agent provided by the application promotes iron supplement by compounding sialic acid and ferrous iron drugs, thereby improving the bioavailability of iron, regulating immunity, promoting intestinal health and achieving various biological activities while supplementing iron.

DEPCT67 What was revealed was a plant-derived iron supplement in particle form, containing iron in the specified amount. At least 40 mg per 100 g of dry weight of the substance, and of which at least 50% by volume of the additive. It has an apparent diameter of less than 500 micrometers;

This invention relates to the field of microbial technology, specifically disclosing a strain of *Lactobacillus paracasei* BL23 that promotes iron absorption and its applications. The preservation number of *Lactobacillus paracasei* BL23 is CGMCC No. 32468. Experimental verification shows that this strain has the ability to reduce ferric iron to ferrous iron, and that specific reducing epitopes exist on the cell surface, enabling it to secrete siderophores. This strain utilizes siderophore secretion and Fe... 3＋ It reduces iron absorption through a dual mechanism and has strong strain specificity, enabling it to independently improve iron deficiency anemia without relying on exogenous iron supplements, thus providing a novel probiotic resource for the prevention and treatment of iron deficiency anemia.

The present invention discloses a heme iron – glycine chelated iron supplement preparation, belonging to the technical field of nutritional and pharmaceutical preparations. The preparation employs a four-source composite of heme iron, glycine chelated iron, ferrous gluconate, and ferrous lactate, enabling iron supplementation via heme receptor absorption, amino acid chelation pathways, and ionic diffusion. This design overcomes the limitations of single iron sources, including gastrointestinal irritation and low absorption of inorganic iron, dietary inhibition of conventional organic iron, and the high cost or slow onset of novel iron sources. The four iron sources act synergistically to reduce free iron ions and integrate multiple absorption pathways. As a result, gastrointestinal irritation is minimized, and the inhibitory effects of phytic acid, oxalic acid, and tannins are reduced, enabling stable and efficient intestinal absorption. The preparation achieves non-irritating, highly bioavailable, and sustained iron supplementation.

This invention provides a glycosylated peptide chelated iron pyrophosphate supplement, its preparation method, and its application. The raw materials for preparing the glycosylated peptide chelated iron pyrophosphate supplement include glycosylated peptides, iron pyrophosphate, and a solubilizer. The glycosylated peptide is a β-glucan-grafted casein phosphopeptide, and the solubilizer is sodium pyrophosphate. The glycosylated peptide chelated iron pyrophosphate supplement of this invention exhibits good water solubility, color stability over a wide pH range, coexistence with nutrients such as vitamin C and oils, high iron loading capacity, good stability in gastric juice, sustained iron release in simulated intestinal fluid, and high iron absorption and utilization rate, significantly improving anemia in iron-deficiency anemia mice. The excellent absorption performance and superior physicochemical properties of the glycosylated peptide chelated iron pyrophosphate supplement of this invention make it a potential candidate for widespread application in the iron supplement market.

This invention discloses a CS-SA bilayer microcapsule, its preparation method, and its application in encapsulating tuna protein peptides for chelated iron, belonging to the field of pharmaceutical technology. First, using tuna minced meat as raw material, tuna protein peptides for chelated iron are prepared through complex enzymatic hydrolysis and chelation reaction. Then, using sodium alginate as the wall material, single-layer microcapsules are prepared using a sharp-pore-coagulation method. Finally, using chitosan as the outer wall material, CS-SA bilayer microcapsules are prepared through electrostatic layer-by-layer self-assembly. The CS-SA bilayer microcapsules prepared by this invention have a dense structure, uniform particle size, and an encapsulation efficiency of up to 45.0%. They exhibit excellent sustained-release performance in simulated gastrointestinal fluid, with release stability significantly superior to single-layer microcapsules and commercially available iron supplements. This invention realizes the high-value utilization of tuna processing byproducts and provides a new approach for the development of iron supplements.
