Abstract: An agent uses at least one selected from the group consisting of an imidazole dipeptide and a metabolite thereof as an active ingredient. The present invention also provides an agent for improving a neuropsychologic function, which contains at least one selected from the group consisting of an imidazole dipeptide and a metabolite thereof as an active ingredient. The present invention also provides an agent for changing expression of a transporter such as SLC23A2, which contains at least one selected from the group consisting of an imidazole dipeptide and a metabolite thereof, and an agent for controlling blood concentration of a cytokine such as IP-10, which contains at least one selected from the group consisting of an imidazole dipeptide and a metabolite thereof, as well as an expression analysis method for detecting improvement or degradation of a neuropsychologic function, and a kit for detecting improvement or degradation of a neuropsychologic function.

Abstract: An anti-aging agent derived from a natural product is provided. The agent uses at least one selected from the group consisting of an imidazole dipeptide and a metabolite thereof as an active ingredient. The present invention also provides an agent for improving a neuropsychologic function, which contains at least one selected from the group consisting of an imidazole dipeptide and a metabolite thereof as an active ingredient.

Abstract: The present invention provides a method for detecting food allergens, antibodies and antigens to prepare the antibodies. The antigens of this invention are a mixture comprising multiple native and/or heated food allergens that IgE antibodies of food-allergy patients recognize. The antibodies of this invention are prepared by immunizing animals with the above-mentioned antigens. The food allergen-detecting method of this invention relates to the above-mentioned antibodies. As the method can detect food allergens and food allergy-inducing foods, it can provide safety to food allergy patients.

Abstract: Disclosed is an extracting solution for use in the extraction of a residual veterinary drug in livestock product or seafood. The extracting solution contains 0.05 to 1% of metaphosphoric acid and comprises a buffer solution of pH 5.5 to 7.5. The extracting solution can extract plural veterinary drugs at the same time, and can be used preferably used for the extraction when the residual veterinary drug is an antibacterial substance. By using the extracting solution, it becomes possible to extract plural veterinary drugs efficiently at the same time without impairment of stability because of its neutral pH range. Hence, the extracting solution enables to determine a residual veterinary drug in livestock product or seafood rapidly in a simple manner.

Abstract: The present invention provides meat products comprising fat contents less than halves of those of conventional meat products and soy protein, and, possessing plasma-cholesterol-suppressing property. Due to reduced fat contents and addition of soy protein with the plasma-cholesterol-suppressing property, the meat products of the invention can improve plasma lipids without reducing favorable texture and taste of the meat products.

Abstract: This invention provides gelatin and gelatin hydrolysate peptide for food, medical and cosmetic use derived from such raw materials as poultry skins, bones and/or tendons, with an isoelectric point at pH 7-10, and characterized by no or low antigen-antibody reactivity to the serum of gelatin-allergic individuals. Since the gelatin and its hydrolysate peptide of the invention are hypoallergenic, they can safely be used for gelatin-allergic individuals and for food, medicine and cosmetics, for which the safety is particularly required.
