Abstract: Provided is a composition for surface treatment of a steel sheet, the composition having excellent resistance to an acid, such as sulfuric acid, and to a coated steel sheet to which the composition for surface treatment is applied, wherein the composition for surface treatment comprises 30-50% wt % of colloidal silica containing 5-20 nm-sized silica, 40-60% wt % of silane containing three or more alkoxy groups, 5-15 wt % of an acrylate-based organic monomer, 0.01-1 wt % of an acid, and 1-15 wt % of a solvent.

Abstract: A composition for enteric hard capsules, and an enteric hard capsule prepared using the composition. The composition for enteric hard capsules may include polyol having at least three hydroxyl groups. During the storage of the enteric hard capsule prepared using the composition, the separation of salt from the capsule is delayed.

Abstract: A functional beverage is disclosed. The disclosed functional beverage comprises a mother liquor and a liquid additive, wherein the liquid additive comprises a poorly water-soluble natural product, an edible surfactant, an edible cosurfactant, and edible oil.

Abstract: Disclosed are an enteric coating composition, an enteric coating film, and a food formulation. The disclosed enteric coating composition comprises an enteric cellulose-based compound, a pH controlling agent, a plasticizer for food, and a solvent, wherein the plasticizer for food comprises acetylated monoglyceride, triacetin, or a mixture thereof, and a content of the pH controlling agent and a content of the plasticizer for food ranges respectively from 10 parts to 40 parts by weight and from 5 parts to 25 parts by weight on the basis of 100 parts by weight of the enteric cellulose-based compound.

Abstract: Disclosed are a composition containing a natural polyphenolic compound and an orally ingestible composition including the composition containing a natural polyphenolic compound. The composition containing a natural polyphenolic compound may include a poorly water-soluble natural polyphenolic compound (PSNPPC) and saponin.

Abstract: A food composition and a soft capsule including the same are disclosed. The disclosed food composition includes 100 parts by weight of a poorly water-soluble natural product, 400 to 8,000 parts by weight of an edible surfactant, 40 to 2,500 parts by weight of an edible cosurfactant, and 40 to 1,500 parts by weight of an edible oil, and has water dispersibility or water solubility.

Abstract: A method of preparing enteric hard capsules, and an enteric hard capsule prepared by the method. The method may include: dissolving an enteric base material, a capsule forming aid, and a neutralizing agent in water at room temperature to prepare an aqueous composition; heating the aqueous composition to a first temperature that is higher than a gelation start temperature of the aqueous composition; cooling the heated aqueous composition to a second temperature that is lower than the gelation start temperature; immersing a mold pin heated to a third temperature that is higher than the gelation start temperature into the aqueous composition; removing the mold pin from the aqueous composition to obtain a film coated on the mold pin; maintaining the film on the mold pin at a fourth temperature that is higher than the gelation start temperature for a first time period to fix the film onto the mold pin; and drying the fixed film at a fifth temperature for a second time period to obtain a capsule shell.
