Abstract: The present invention relates to a cosmetic composition comprising a fermented chestnut husk extract or a fraction thereof as an active ingredient. The fermented chestnut husk extract or fraction thereof according to the present invention can be used to provide a cosmetic composition that exhibits an increased total phenolic content, high antioxidative activity, and excellent skin whitening and wrinkle reduction due to the fermentation, extraction, and fractionation processes thereof.

Abstract: The present invention relates to a method of manufacturing a hyaluronate film and a hyaluronate film manufactured thereby, and more particularly to a method of manufacturing a hyaluronate film through a solvent-casting process or using an automatic film applicator that facilitates mass production and to a hyaluronate film manufactured thereby, which is useful as a mask pack for cosmetics, a patch for medicaments and medical devices, a film-type adhesion inhibitor, etc. Unlike conventional liquid products, the hyaluronate film according to the present invention has a dry surface and thus entails no concern about microbial contamination, is easy to produce/manage/distribute/use, and has superior mechanical properties, whereby it can be utilized for various applications such as packs, patches, artificial skin and the like for cosmetics, medicaments, and medical devices.

Abstract: Disclosed is method for preparation of a starch phosphate using phytate. The method enables the preparation of a starch phosphate with improved physical properties such as high transparency, solubility, swelling power, and storage stability by the phosphorylation of a starch using naturally occurring phytate rather than using a synthetic chemical. Due to these advantages, the starch phosphate is expected to replace conventional chemically modified starches. In addition, the method enables the preparation of a starch phosphate based on a simple modification. The use of the starch phosphate greatly contributes to improvements in the quality and storage stability of various starchy foods. Therefore, the starch phosphate is expected to find application in the food industry, including starchy foods.

Abstract: The present invention relates to an antioxidant, skin-whitening and wrinkle-reducing multifunctional cosmetic composition containing a fermented rice by-product extract or a fraction thereof as an active ingredient. By using a fermented rice by-product extract or a fraction thereof according to the present invention, the total phenolic content of a rice by-product can be increased by means of fermentation, extraction and fractionation, and a cosmetic composition showing high antioxidant capability and excellent skin-whitening and wrinkle-reducing effects can be provided.

Abstract: The present invention relates to a method for preparing physically modified starch by utilizing heating and freezing-thawing (FT) on starch or a starch-gum mixture obtained by adding gum to starch. According to the method for preparing physically modified starch of the present invention, the weakness of natural starch can be supplemented, and heat and shear stability, gel-forming ability, and storage stability thereof can be improved. Especially, modified starch with a significantly improved modification effect can be produced by the addition of gum and the heating and freezing-thawing treatment. The present invention can significantly improve quality and storage stability of various starchy foods through a simple modification procedure, and thus it is expected that the present invention can be variously utilized in industry field of food including starchy food.
