This invention relates to the field of food packaging and functional food technology, and discloses an edible soybean residue-based cup with preservation and health-promoting functions, and its preparation method. The cup includes a soybean residue-based preform, which is formed by extrusion injection molding from soybean residue ultrafine powder, composite starch, and pH-sensitive health-promoting microcapsules. Its inner wall is coated with an active preservation layer containing glucose oxidase, catalase, and nisin, and its outer surface is coated with a physical barrier film formed by beeswax and shellac curing. This invention improves the water resistance and structural stability of the substrate by constructing a physical barrier film on the outer wall to seal pores; it actively reduces the oxygen partial pressure inside the cup and inhibits microbial growth through the synergistic effect of the multi-enzymatic reaction and antimicrobial peptides in the inner wall preservation layer, thus extending the shelf life of the food; and it combines microcapsule technology to protect the active core material in gastric juice and target its release in the intestine, improving the bioavailability of the health-promoting components.

Solutions containing cyclodextrins for imparting odor control to materials used in absorbent products and associated products and methods. The solutions containing cyclodextrins for imparting odor control to materials used in absorbent products contain an optional polar organic solvent, water, cyclodextrin, and one or more odor-controlling compounds. The solutions can be used to uniformly apply a homogeneous solution of a cyclodextrin complex onto a solid surface whereby the cyclodextrin complex precipitates in situ on the solid surface. The cyclodextrin complex precipitates deposited from these solutions rapidly release odor-masking scents when hydrated with urine and can be deposited on substrates more effectively than cyclodextrin complexes in solid form.

The application belongs to the technical field of paint preparation, and particularly relates to a paint composition for bridge concrete and a preparation method thereof. The paint composition for bridge concrete comprises acrylic emulsion, modified diatomite, cationic beta-cyclodextrin, nano-silicon dioxide, dispersing agent, defoaming agent, leveling agent and water. The preparation process of the modified diatomite is as follows: the diatomite is pretreated; the pretreated diatomite is added into a solution of vinyl triethoxysilane, and the pretreated diatomite is obtained after reaction; the pretreated diatomite is added into a solution of tripropyleneglycol dipropyl acrylate, 2-hydroxy-4-methacryloyloxybenzophenone and initiator, and the modified diatomite is obtained after heating reaction. The application significantly improves the ultraviolet aging resistance, water resistance and corrosion resistance of the paint by introducing the modified diatomite and cationic cyclodextrin.

The invention discloses a star-shaped triblock copolymer double-layer intelligent antifouling coating for marine equipment antifouling and application of the star-shaped triblock copolymer double-layer intelligent antifouling coating. The coating adopts a double-layer synergistic and functional partition design, wherein the lower layer is a PCL-CO-GA triblock copolymer with a star-shaped network structure, and provides mechanical support and a long-acting antifouling background; the upper layer is a cyclodextrin modified photocatalytic metal oxide porous functional layer, organic pollutants on the surface are actively removed by utilizing the photocatalytic self-cleaning effect of the cyclodextrin modified photocatalytic metal oxide porous functional layer, and a microbial adhesion foundation is destroyed. According to the design, multiple functions such as bacterium resistance, algae resistance, self-cleaning, oxidation resistance and wear resistance are integrated, laboratory tests show that the inhibition rate of the coating on common marine bacteria and algae reaches up to 99.9%, and the durability of the coating is remarkably superior to that of a traditional technology. Compared with a traditional heavy metal anti-fouling technology, the anti-fouling agent has the outstanding advantages of being environmentally friendly, advanced in anti-fouling mechanism, not prone to inducing drug resistance, long in acting time and the like, and has wide application prospects in the green anti-fouling field of equipment such as ships and ocean platforms.
