The invention relates to an antibacterial protector for drink cans that comprises an upper part (1) partially covering the upper part of the can (5) and fitted to the edge thereof, wherein an outer vertical perimeter skirt (2) extends from the edge of the upper part in contact with the upper edge of the can (5), and an inner skirt (3) extends from the edge of the upper part (1) in the space inside the can, the inner skirt preventing access to the space defined below the upper part (1), at least one end of the vertical perimeter skirt (2) comprising a tab or flap (4) to facilitate the removal of the protector. In addition to the inside face of the protector, at least the outer vertical perimeter skirt (2) comprises a hypoallergenic adhesive. The invention prevents the drink can from becoming contaminated or infected with bacteria, especially in the area that comes into direct contact with the mouth.

This invention belongs to the food field, specifically relating to a hypoallergenic, gluten-free, non-wheat tiger nut fermented noodle product and its preparation method. The hypoallergenic, gluten-free, non-wheat tiger nut fermented noodle product comprises the following components: raw material powder, alkaline protease, transglutaminase, additives, and water; the raw material powder is a mixture of tiger nut meal powder and rice flour. The technical solution of this application utilizes a fermentation system using alkaline protease and transglutaminase. Alkaline protease hydrolyzes the amide and peptide bonds of proteins, causing acylation reactions that cross-link protein molecules, producing a network structure and improved flavor and quality. Transglutaminase catalyzes the acylation reaction between the amide group in glutamine and the ε-amino group on lysine peptides, causing cross-linking of protein molecules to form the target protein and produce the desired product.

A method for manufacturing biotic gloves and a hypoallergenic biotic glove are provided. The method includes dipping the molds into a coagulant solution and performing a pre-vulcanization treatment using alkaline protease, ultraviolet irradiation, and polyols derived from cellulose materials. The latex-coated molds undergo drying, washing, vulcanization with specific curing agents and accelerators, chlorine washing, and a secondary dipping in polyurethane to form a hypoallergenic inner layer. The resulting gloves feature a multilayer structure, including a first layer, a second layer, and a third layer. The first layer includes nitrile butadiene rubber, chloroprene rubber, or isoprene rubber combined with polysaccharide biotic materials. The second layer includes a natural rubber layer or other synthetic rubber combined with polysaccharide biotic materials, and the third layer includes a polyurethane layer. The final gloves have a biotic content of 3-40%, a tensile strength of 14-40 MPa, and an elongation at break of 350-800%.

The present invention can provide a method for preparing a fermented nano-emulsifier composition comprising a product obtained by fermenting an oil with a skin flora, and a skin-friendly composition by minimizing the contents of synthetic raw materials according to such a method. Further, it is possible to improve an emulsification power by forming a nano-emulsion in a size of nm, to be adopted to various formulations by enhancing stability of the composition, and to be easily applied to various formulations requiring a function of hypoallergenic skin due to minimization of the skin irritation.

A hand-held electronic nose cleaning device with built-in wire lubrication and disposable cotton cleansers.

When the product is at rest, aside from nasal cleansing, this detachable hypoallergenic fluid tube provides hygienic care for various parts of the body.

The present invention is a water-slip membrane 10 that can maintain fixed drop characteristics or greater even after a weathering test or saline spray test, the water-slip membrane comprising a base layer 14 formed on a glass base material 12, and a lubricating layer 16 held on the base layer 14. The base layer 14 is formed by modifying a reactive functional group on the surface of the glass base material 12, and the lubricating layer 16 is composed of a polymer containing a reactive functional group capable of covalent bonding with the reactive functional group of the base layer 14. A portion of the reactive functional group of the base layer 14 and a portion of the reactive functional group of the lubricating layer 16 are covalently bonded. Furthermore, the base layer 14 contains a cyclic conjugated functional group modified on the surface of the glass base material 12, and the lubricating layer 16 includes a polymer containing hydrogen atoms charged to δ+. A portion of the cyclic conjugated functional group of the base layer 14 and a portion of the hydrogen atoms charged to δ+ of the lubricating layer 16 have π-electron interaction.

The invention discloses a preparation method of a hypoallergenic acellular matrix implant, and belongs to the technical field of biomedical materials. The preparation method comprises the following steps: swelling animal soft tissues in an alkaline solution for a short time, quickly freezing and crushing; placing the crushed sample in a hypertonic-hypotonic solution system, and performing efficient and mild decellularization treatment through circulating oscillation; then, endotoxin and other sensitizers are specifically removed by adopting a chromatography technology in sequence, denatured protein is washed by utilizing a salt solution, and finally, purification is performed through ultrafiltration or dialysis. According to the method, cell debris, nucleic acid and endotoxin can be deeply removed through multi-step synergy and combination of hypertonic-hypotonic circulating decellularization and chromatographic purification, the immunogenicity of an implant is remarkably reduced, and the natural three-dimensional structure and biological activity of an extracellular matrix are reserved to the maximum extent. The implant prepared by the method has the characteristics of low DNA residual quantity, extremely low endotoxin content and excellent biocompatibility, and is suitable for soft tissue repair and regeneration.

This invention discloses a hypoallergenic edible sesame protein and its preparation method, belonging to the field of food processing. The preparation method includes: dissolving sesame protein in water and adjusting the pH to alkaline to obtain a sesame protein solution; adding rosmarinic acid to the sesame protein solution and reacting it at room temperature in the dark to obtain a sesame protein-rosmarinic acid covalent complex solution; adding D-ribose to the sesame protein-rosmarinic acid covalent complex solution, and incubating, cooling, dialyzing, and freeze-drying under water bath conditions to obtain hypoallergenic edible sesame protein. This invention effectively disrupts the allergenic epitopes of sesame protein by adding phenolic and sugar substances, reducing its allergenicity and improving its functional properties to a certain extent, making it more suitable for the requirements of industrial production in food enterprises. Simultaneously, this invention provides an efficient and feasible technical approach for the high-value development and safe application of sesame protein, possessing significant industrial value and application prospects.
