5 results about "Zinc absorption" patented technology

The invention belongs to the technical field of bioactive peptides, and discloses a white snakehead oligopeptide as well as a preparation method and application thereof. The white snakehead oligopeptide is selected from one of oligopeptides with amino acid sequences as shown in SEQ ID NO.1-8. The invention further discloses a preparation method of the white snakehead oligopeptide. The polypeptide provided by the invention has a relatively high ferrous / zinc absorption rate to a human body, has a certain function of treating iron-deficiency anemia and zinc deficiency, and has a good application prospect in mineral (iron / zinc) supplements, functional foods and health-care products.

Methods and compositions use a galactooligosaccharide (GOS) for increasing absorption of zinc, such as zinc naturally present in ingredients of the composition and / or present in a food product, a meal or a diet, wherein the food product, meal or diet is combined with the composition and / or consumed separately from the composition. Some embodiments are directed to a milk-based composition comprising zinc intrinsically present in the milk, further comprising milk protein, and further comprising a mixture of lactose, glucose, galactose and the galactooligosaccharide (GOS). In some embodiments, the milk-based composition does not contain exogeneous zinc, such that the only zinc in the composition is the zinc intrinsically present in the milk.

The invention relates to the technical field of medicinal breeding of special insects, in particular to a method for improving zinc absorption and anti-inflammatory components of maggots, which comprises the following steps: preparing bullfrog-poria cocos-herba epimedii fermented feed; on the basis of the fermented feed, three-generation continuous directional feeding and screening are carried out on maggots, low zinc stress is applied to the first generation, individuals with optimized zinc transport related capacity are screened, LPS inflammation stress is applied to the second generation, and individuals with optimized anti-inflammation related capacity are screened. Applying drying stress to the third generation, and screening the individuals with the zinc content and the anti-inflammatory peptide expression quantity reaching the standard; through the three generations of screening, a maggot population with stable zinc content and stable anti-inflammatory peptide expression quantity is obtained. Through a specific fermented feed formula and a multi-generation directional breeding technology, the zinc enrichment capacity and anti-inflammatory efficiency of maggots are effectively improved, and the maggots become biological resources suitable for the fields of nutritional supplement and medical treatment.

The application discloses a casein peptide-zinc chelate TEDELQDKIHP-Zn for promoting zinc absorption, and an amino acid sequence of a polypeptide part of the casein peptide-zinc chelate is Thr-Glu-Asp-Glu-Leu-Gln-Asp-Lys-Ile-His-Pro; and a polypeptide and zinc chelate have a chelate ratio of 1:0.7. The casein peptide-zinc chelate TEDELQDKIHP-Zn has high gastrointestinal digestion stability, good absorption performance, and an effect of promoting zinc absorption is obviously better than that of traditional zinc supplements, such as zinc sulfate and zinc gluconate. The casein peptide-zinc chelate has very important significance for developing food, health products and medicines with a zinc supplement function.

The application discloses a coagulase Heyndrickx strain CCFM1539 with high spore yield and promoting intestinal calcium and zinc absorption and a postbiotic thereof, and belongs to the technical field of microorganisms. In the application, the absorption amount of zinc and calcium is significantly increased, which is specifically embodied in the following aspects: (1) the coagulase Heyndrickx strain CCFM1539 strain cell component significantly improves the expression level of zinc and calcium transport protein genes of Caco-2 cells; (2) the coagulase Heyndrickx strain CCFM1539 significantly increases the total transport amount of zinc and calcium of a Caco-2 cell monolayer model; and (3) the coagulase Heyndrickx strain CCFM1539 significantly promotes the absorption of zinc and calcium in a mouse body. Therefore, the coagulase Heyndrickx strain CCFM1539 has great application prospect in promoting intestinal zinc and calcium absorption.
