Technical Field
The invention belongs to the technical field of animal blood products, and relates to a preparation method of fermentation type red date chelated peptide iron.
Background
Hemoproteins are a large group of metal proteins containing protoporphyrin IX as a prosthetic group, and perform different biological functions according to different protein molecule composition modes of connecting proteins and metal ions on the prosthetic group of the hemoprotein and wrapping heme by a protein polypeptide chain. Ferrohemoglobin, the most prominent component of red blood cells, is composed of globin and heme. The heme molecule is a small molecule with a porphyrin structure, nitrogen atoms on four pyrrole rings in porphyrin are coordinately bound with a ferrous ion at the center of the porphyrin molecule, and nitrogen atoms on indole side chains in histidine residue at the 8 th position in a globin peptide chain are coordinately bound with the ferrous ion from the upper part of the plane of the porphyrin molecule.
The protein is finally decomposed into oligopeptides and free amino acids by the action of digestive enzymes of the gastrointestinal tract. Oligopeptides are more advantageous in absorption than free amino acids and can be absorbed intact into the blood. The polypeptide-porphyrin iron which is the decomposition product of the hemoprotein has strong iron supplementing effect, strong oxidation resistance and health care function. The polypeptide is used as a nutritional factor with multiple functional properties such as oxidation resistance, fatigue resistance and the like, and can also promote the absorption of non-chelated iron.
The red dates are one of recognized foods with the functions of iron supplement and blood supplement, each hundred grams of red dates contain 2.3mg of iron, and simultaneously contain rich vitamin C, but the iron in the red dates is not easy to be utilized and absorbed by human bodies, in the existing products, the red date products are directly mixed with iron chelating peptides to prepare iron supplement products, but the chelated protein peptides are difficult to further promote the absorption of iron elements contained in the red dates, so that part of plant source iron in the products can not be fully absorbed.

In order to achieve the above object, the present invention is achieved by the following technical solutions.
A preparation method of fermentation type red date chelated peptide iron comprises the following steps:
1) pulping red dates, adding cellulase for enzymolysis to obtain a jujube pulp enzymolysis liquid;
2) adding haematochrome protein into the jujube pulp enzymatic hydrolysate, and performing homogenization treatment;
3) inoculating yeast and lactobacillus into the homogenized mixed liquid for fermentation for 1-3 d;
4) adding protease into the fermented solution for enzymolysis for 2-4 h; then concentrating and drying to obtain the finished product.
Preferably, the mass percent of the cellulase is 0.5-2.5%.
Preferably, the enzymolysis time in the step 1) is 2-6 h.
Preferably, the hemoglobin protein is obtained by subjecting animal blood to anticoagulation treatment, centrifugal separation of erythrocytes, erythrocyte breakage, isoelectric point precipitation and centrifugal separation.
Preferably, the homogenization treatment is to homogenize the date pulp enzymolysis liquid added with the haematochrome protein by a homogenizer for 1-2 h.
Preferably, the mass ratio of the jujube pulp enzymolysis liquid to the hemoprotein is 1: 1.5-2.5.
Preferably, the pH of the homogenized mixed liquid is adjusted to 5.0-6.0.
Preferably, after enzymolysis by protease, heating to 70-85 ℃, and treating for 15-30 min; and then filtered.
Preferably, the drying is spray drying.
Compared with the prior art, the invention has the following beneficial effects:
the mechanism of the preparation method of the fermentation type red date chelated iron peptide is as follows: firstly, red dates are subjected to wall breaking pulping, so that plant fibers in the red dates are fully softened, and meanwhile, sugar and protein components are fully dissolved out; further enzymolysis of fibrous components with cellulase to release iron ion and dissolve in the pulp; adding heme protein and homogenizing to break heme protein into finer structures, wherein red date pulp and broken heme protein are fully mixed in the process, iron ions in the date pulp are further chelated with exposed polypeptide after breaking to form stable iron chelated protein, the activity of iron elements in plants is fully activated, and the iron absorption efficiency of the iron elements is improved by chelation with micro-protein; finally, carrying out enzymolysis on the chelated protein obtained by physical treatment by using protease to further carry out enzymolysis on the peptide iron product; the final product is rich in two components of peptide iron and chelating peptide iron, so that the active iron content of the product is greatly improved, and the absorption efficiency of iron elements is effectively improved.

After the products of examples 1-3 are added, the activity of Caco-2 cells is improved, the iron ions obtained after the simulated digestion of the target sample are absorbed by the Caco-2 cells, the absorption rate of the iron ions is improved along with the prolonging of the transport time, and the absorption rate of the iron ions of example 3 is 1.56 times that of the peptide iron product and is 1.52 times that of the mixed product of the peptide iron and the jujube pulp.
While the invention has been described in further detail with reference to specific preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
Claims (9)
