Abstract: The present invention relates to a manufacturing method of kimchi with shelf stability and high quality under the severe environment, more precisely, a manufacturing method of kimchi with shelf stability and high quality under the severe environment such as desert, alpine regions, poles and space which includes the step of irradiation after heating, gas exchange packaging and quick freezing. The manufacturing method of kimchi of the present invention reduces the chances of deterioration of the sensory quality and physicochemical characteristics caused by the conventional sterilization methods including high temperature and high pressure treatment and high dose of irradiation, so that kimchi produced by this method has excellent shelf stability under the severe environment.

Abstract: Disclosed are a fibroin with increased molecular weight and improved antioxidant activity, tyrosinase inhibitory ability and cytotoxicity to cancer cells, which has a molecular structure modified by irradiation, a method for production thereof, use of the irradiated fibroin in various applications for enhancing antioxidant activity, tyrosinase inhibitory ability and/or cytotoxicity to cancer cells such as foods, cosmetics, medicines, etc.

Abstract: Disclosed are sericin having improved antioxidant and tyrosinase inhibitory abilities and increased molecular weight by irradiation, which causes a modification of a sericin molecular structure, a preparation method thereof and use of the irradiated sericin in various applications including food products, cosmetics and/or pharmaceutical products and medicines to improve antioxidant ability and/or tyrosinase inhibitory functions.

Abstract: Disclosed herein is a method for the preparation of low-molecular weight beta-glucan by irradiation. The low-molecular weight beta-glucan prepared by irradiation shows a random distribution of all beta-glucan structures, low viscosity and high water solubility, and acts as an excellent antioxidant and to activate immune cells, finding useful application in many fields including the food, medical and cosmetics industries.

Abstract: Disclosed is an irradiation method which includes addition of vitamin C during sterilization of bone restorative demineralized bone matrix (DBM) with irradiation, so as to inhibit reduction of physical properties of a carrier containing DBM caused by irradiation and protect DBM formable bone morphogenetic protein (BMP) from irradiation. The method according to the present invention can provide bone restorative materials with more excellent stability and effectively controlled modification of physical properties by employing a sterilization process accompanied with addition of vitamin C during irradiation.

Abstract: Disclosed is a method for producing demineralized bone matrix with improvement of releasing bone morphogenetic protein by irradiating the demineralized bone matrix, the demineralized bone matrix produced by the producing method, a method for extracting bone morphogenetic protein using the demineralized bone matrix, and the bone morphogenetic protein extracted by the extracting method. The demineralized bone matrix produced according to the present invention and the bone morphogenetic protein extracted by using the demineralized bone matrix can be advantageously used in manufacturing bone restorative implants, bone growth accelerating compositions, and/or health aids or supplementary food products.

Abstract: The present invention relates to a vaccine composition for the prevention and treatment of allergic disease comprising irradiated ovalbumin as an effective ingredient, more precisely a method for preparing an immunogen of a vaccine for the prevention and treatment of allergic disease using the irradiated ovalbumin which is separated and purified from the albumen of an egg, a vaccine composition for the prevention and treatment of allergic disease comprising the irradiated ovalbumin as an effective ingredient, and a method for the prevention and treatment of allergic disease using the vaccine comprising the irradiated ovalbumin. In the mouse vaccinated with the irradiated ovalbumin, humoral and cell mediated immune responses were both reduced, suggesting that allergic reaction was inhibited. Thus, the composition of the present invention can be effectively used as a vaccine for the prevention and treatment of allergic disease.

Abstract: Disclosed herein is a packaging method for removing off-odors from irradiated foods using charcoal. In a package, foods are irradiated along with charcoal so as to remove the off-odors produced. The method can effectively remove off-odors from irradiated foods without influencing the sensory and physicochemical properties thereof, thereby allowing irradiation to be conducted and thus greatly contributing to food safety.
