Abstract: An object of the present invention is to provide an oral retention composition in which a decrease in the viscosity of an acidic polysaccharide due to a functional substance is suppressed even when the functional substance is basic. The present invention relates to an oral retention composition comprising at least one compound selected from the group consisting of shellac and zein, a functional substance, and an acidic polysaccharide, the functional substance coated with the at least one compound selected from the group consisting of shellac and zein being mixed with the acidic polysaccharide.

Abstract: An agent of the present invention comprising poultry feet or a processed product thereof, preferably a hydrolysate of an extract of poultry feet, promotes hyaluronic acid production, thereby exhibiting excellent effects of preventing or treating a joint disorder, improving skin dryness, wrinkles or skin tension, moisturizing the skin, etc. The agent is thus useful as a medicament, a quasi-drug, a cosmetic product, a food product or an animal feed.
