ActiveUS9211275B2Reduce serum cholesterol and/or triglyceride levelLowering of total serum cholesterol levelHydroxy compound active ingredientsMetabolism disorderChemistryNutritional composition
The subject disclosure provides compositions for reducing serum cholesterol and / or triglyceride levels in subjects. These compositions can comprise racemic β-hydroxybutyrate or D-β-hydroxybutyrate, optionally in the acid form, physiologically compatible salts of racemic β-hydroxybutyrate or D-β-hydroxybutyrate, esters of D-β-hydroxybutyrate, oligomers of D-β-hydroxybutyrate containing from 2 to 20 or more monomeric units in either linear or cyclic form, racemic 1,3 butandiol or R-1,3 butandiol alone and can be, optionally, administered in conjunction with a low fat diet to a subject. Alternatively, compositions comprising racemic β-hydroxybutyrate or D-β-hydroxybutyrate, optionally in the acid form, physiologically compatible salts of racemic β-hydroxybutyrate or D-β-hydroxybutyrate, esters of D-β-hydroxybutyrate, oligomers of D-β-hydroxybutyrate containing from 2 to 20 or more monomeric units in either linear or cyclic form, racemic 1,3 butandiol, R-1,3 butandiol or combinations thereof can be formulated as nutritional supplements (also referred to as nutritional compositions) or incorporated into therapeutic compositions containing a) anti-hypertensive agents; b) anti-inflammatory agents; c) glucose lowering agents; or d) anti-lipemic agents) which are administered to a subject, optionally in combination with a low fat diet, in order to cause a reduction or lowering of: serum cholesterol levels; triglyceride levels; serum glucose levels, serum homocysteine levels, inflammatory proteins (e.g., C reactive protein) and / or hypertension in treated subjects. Alternatively, compositions disclosed herein can be administered alone, or in combination with other therapeutic agents to prevent or reverse vascular disease.

Butyrate starch preparing method

ActiveCN109400725ASolve the problem of irritating odor and volatilePrevent volatilizationFood ingredient functionsButyric anhydrideLarge intestine
The invention discloses a butyrate starch preparing method and belongs to the technical fields of preparation and application of modified starch and deep processing of agricultural products. Accordingto the butyrate starch preparing method, starch serve as the principal raw material for esterification with butyric anhydride to achieve stabilization of butyric acid and small releasing of the butyric acid in gastric juice; resistant starch prepared through esterification of the butyric acid and the starch can well avoid being absorbed in small intestines, resist digestion by enzymes secreted bybrush borders, selectively release micromolecular effective load in large intestines; fermented by enteric microorganisms, the resistant starch can produce more short-chain fatty acids and probiotics, thereby improving the bioavailability of the butyric acid and expanding the application range of the starch. Compared with other butyric acid products, the butyrate starch is odorless and can be esterified into the resistant starch to convey the butyric acid to the rear end of the intestines; the butyrate starch can be fermented by the enteric microorganisms and decomposed by bacterial esteraseinto butyric acid and other short-chain fatty acids and increase the content of the probiotics, thereby belonging to probiotic products.

Antibacterial coating layer and preparation technology thereof

The invention relates to an antibacterial coating layer and a preparation technology thereof. The antibacterial coating layer comprises 0.01% to 0.05% of Fe3O4 (ferroferric oxide)-doped TiO2 (titaniumdioxide) nanoparticles, and also comprises a fluoride acrylic emulsion, an epoxy resin emulsion, melamine, carbodiimide, a talcum powder, sodium polymethacrylate, water-borne color paste, trimethyl hydroxyl amyl alcohol isobutyric acid ester, propylene glycol, a high fatty acid ester compound, titanium dioxide, polyoxyethylene alkyl phenol ether, 1,2-benzisothiazolin-3-ketone, alkanolamine and water. The antibacterial coating layer is mixed by the components. The Fe3O4-doped TiO2 (titanium dioxide) nanoparticle is prepared from Ti(SO4)2 (titanium sulfate), Fe3O4, ammonia water, sodium dodecylbenzene sulfonic acid, nitric acid, hydrochloric acid and water through co-precipitation. Compared with the antibacterial coating layer containing pure TiO2 nanoparticles, the antibacterial coating layer has the advantages that the absorption spectrum is broader; the strong bacteria inhibiting and killing activity is realized under the visible light; a smaller amount of nanoparticles is requiredin the production process, and the cost is obviously reduced.

Precursor compound of hexahydro-beta-acid component compound, feed composition and application thereof

PendingCN112500289AOvercoming the problem of active ingredient degradationImprove stabilityPreparation from carboxylic acid halidesOrganic compound preparationBiotechnologyPropionate
The invention discloses a precursor compound of a hexahydro-beta-acid component compound, a feed composition and an application thereof. The invention relates to a precursor compound of a hexahydro-beta-acid component compound, or a solvate of the precursor compound and a feed acceptable salt, the structure of the precursor compound is shown as a formula (I), R1 is selected from substituted or non-substituted C1-C2 alkyl, and R2 or R3 is independently selected from H and substituted or unsubstituted straight-chain or branched-chain C2-C4 carbonyl. According to the invention, the fatty acid esterification precursor compound of the hexahydro-beta acid-component compound is found to have good stability under a high-temperature condition, and the problem of degradation of effective componentscaused by high-temperature granulation of the hexahydro-beta-acid component compound in a feed processing process is solved. Further, the invention also finds that the hexahydro-beta acid component compound propionate or butyrate and the feed acceptable salt or solvate thereof in the fatty acid esterification precursor compound of the hexahydro-beta acid component compound, not only can bear the high temperature course of feed processing, but also has the equivalent effect of the hexahydro-beta acid component compound when being applied to breeding.
