Description

Mature vinegar nanoparticle-chelates of zinc preparation method
Technical field
The present invention relates to a kind of preparation methods of mature vinegar nanoparticle-chelates of zinc.
Background technique
In process, organic molecule and oligomer in raw material are heated to occur series reaction to food, this with hydro-thermal/ The process of solvent structure nanoparticle is similar, and mature vinegar is mainly gelatinized by raw materials such as sorghum, yeast, wheat bran, Gu Kang, is sent out The techniques such as ferment, smoked unstrained spirits are brewed, and there is the process inevitably heated to raw material in process of production, in this process In, protein and polysaccharide in cereal materials are degraded to short peptide chain, amino acid and oligosaccharides, mutually occur between these substances anti- It answers, forms the nanoparticle in mature vinegar, this food-borne nanoparticle biological safety height and good biocompatibility.
Zn-ef ficiency is required microelement in animal body, and the enzyme containing metallic zinc is widely distributed in human body, is had Studies have shown that zinc is the important component of 40 various metals enzymes in human body, and related with the activity of more than 30 kinds of enzymes, Zn-ef ficiency Body eubolism and growth and development are also maintained, zinc mainly participates in the conjunction of nucleic acid and protein in human body by a variety of enzymes At metabolic processes such as, energetic supersession, redox, and then influences the metabolism of body and growth and development, zinc-deficiency and can reduce core The activity of thuja acid synzyme, thymidylic acid enzyme, archaeal dna polymerase and RNA polymerase sends out the synthesis of nucleic acid and protein Raw obstacle is interfered so as to cause body cell division and growth, Zn-ef ficiency content highest in human brain, especially with hippocampus With cerebral cortex layer content highest, and the two and behavioral function are closely related, thus the distribution of zinc in brain can react its The important function in behavioral function is adjusted, when zinc-deficiency, the stability of cell membrane changes in brain, and brain cell is by serious Damage, brain development is obstructed, and memory level also will receive influence, although zinc source very abundant in nature, zinc is in people Intracorporal Absorption And Metabolism is limited by many factors;In order to prevent and treat and alleviate the generation of Zn-ef ficiency deficiency disease, every country Area all strengthens Zn-ef ficiency in food according to the actual situation, currently, Zn-ef ficiency supplement mainly passes through two kinds of approach: first is that using rich The food of Zn-ef ficiency is supplemented;Second is that being supplemented by taking supplementing preparation, supplemented using the food of zinc-rich element, Due to the finiteness of its constituent content, body can not be fully met to the needs of metallic element;Therefore, people mainly utilize benefit It fills agent to be supplemented, Zn-ef ficiency supplementing preparation comes into being in this context, is developed so far from first generation Zn-ef ficiency replenishers, Through changing after four times, first generation Zn-ef ficiency replenishers are inorganic salt types, and manufacture craft is simple, and production cost is low, however Biological absorption is lower, and to the irritating effect of gastrointestinal tract;Second generation Zn-ef ficiency replenishers are to do ligand by organic acid to synthesize Preparation, good absorbing, but preparation process are complicated, have the undesirable clinical response such as nauseous constipation, are also unsuitable for the spies such as diabetes patient Different group;Third generation Zn-ef ficiency replenishers are the preparations that ligand synthesis is done with amino acid, and it is steady not to be only soluble in water also chemical property Fixed, absorption rate in vivo is also higher, but there is also certain defects in terms of chelation mechanism and operating;Forth generation zinc member Plain replenishers are the preparations that ligand synthesis is done with peptide, are also equipped with one except the advantages of making the preparation of ligand synthesis with amino acid Fixed antioxidant activity, but the hydrolysis of control peptide and the production technology of purity are still not perfect.
The Zn-ef ficiency nutritional supplement final product quality of prior art production is unstable, some product tastes are bad, absorptivity It is lower and expensive, these problems all urgent need to resolve, nanoparticle surface functional group rich in, and have good Water solubility, using food-borne nanoparticle as carrier carry out Zn-ef ficiency nutrient delivery, have good biocompatibility and Higher biological safety.
Summary of the invention
The object of the present invention is to provide it is a kind of for the first time using in mature vinegar naturally occurring nanoparticle as delivery vector, nanometer Particle-chelates of zinc can be added in food, realize nanoparticle-chelates of zinc preparation side of the nutritional supplementation of Zn-ef ficiency Method.
