Abstract: The present invention relates to a peptide that is derived from a milk protein and has an antioxidative effect, an antioxidant that includes the peptide as an active ingredient, and an antioxidative food, drink, or feed that includes the peptide. The present invention also relates to a peptide that is derived from a milk protein and has an adiponectin production promotion effect, an adiponectin production promoter that includes the peptide as an active ingredient, and an adiponectin production promotion food, drink, or feed that includes the peptide. The present invention further relates to a blood adiponectin level increase promotion and/or decrease inhibition agent that includes a component contained in cheese as an active ingredient, and a blood adiponectin level increase promotion and/or decrease inhibition food or drink that includes a component contained in cheese.

Abstract: It is intended to provide an oral flora-improving agent capable of forming a favorable flora in the oral cavity and a food or a drink for improving the oral flora. An oral flora-improving agent containing as an active ingredient a ganglioside and a food, a drink, or a feed for improving the oral flora containing the ganglioside exhibit an antibacterial effect on harmful bacteria in the oral cavity, which are undesirable from the viewpoint of decay and diseases such as periodontal disease, and a growth-improving effect on useful bacteria to be preserved in the oral cavity. Further, the ganglioside is efficaciously used as an active ingredient in an antibacterial agent or an antibacterial drink, food, or feed, a growth promoter, or a food, a drink, or a feed for promoting growth.

Abstract: To provide anti-mental fatigue drugs as well as foods, beverages, and fodders that can be taken daily and effective for relieving mental stress and inducing relaxation by intake. An anti-mental fatigue drug containing iron-binding lactoferrin as an active ingredient and foods, beverages, and fodders containing the drug.

Abstract: A dead cell of a lactic acid bacterium or a culture containing the dead cell of a lactic acid bacterium is added to the dairy products such as yogurt, cheese, milk beverage or the like in an amount of 0.001 wt % or more in dry weight of the dead cell, therefore, it is possible to enhance the growth of a lactic acid bacterium, to shorten the time required for fermentation, and to improve the viability of a lactic acid bacterium during storage over a long period, without affecting the flavor or production cost of the dairy product.

Abstract: Our objective is to provide a novel lipid metabolism-improving reagent effective in preventing and treating hyperlipidemia and obesity and to provide this reagent in food, beverages, nutritional supplements, and fodders with the ability to improve lipid metabolism. The whey protein hydrolysate as the active ingredient in the lipid metabolism-improving reagent has a molecular weight distribution of 10 kDa or less, with the main peak between 200 Da to 3 kDa, average peptide chain length (APL) of 2-8, free amino acid content of 20% or less, antigenicity of 1/10,000 or less compared with that of ?-lactoglobulin.

Abstract: Disclosed is a substance capable of promoting the repair of a fractured part in a fracture caused by an external force, fatigue or a disease. Also disclosed is a method for producing the substance. Further disclosed is a product capable of promoting the repair of a fracture, such as a food, a beverage and a feed, which comprises the fracture repair promoter. Specifically disclosed is a fracture repair promoter comprising, as an active ingredient, a fraction containing a milk-derived basic protein. In the promoter, the fraction containing the milk-derived basic protein is produced by contacting milk or a milk-derived raw material with a cation exchange resin to cause the adsorption of the basic protein on the cation exchange resin and eluting a fraction adsorbed on the resin by means of an eluent having a salt concentration of 0.1 to 1.0 M.

Abstract: Disclosed is an agent for accelerating the increase in and/or preventing the decrease in the blood adiponectin level, or a food, beverage or animal feed for accelerating the increase in and/or preventing the decrease in the blood adiponectin level, which comprises a culture or cell of a lactic acid bacterium belonging to the genus Lactobacillus, particularly Lactobacillus gasseri or Lactobacillus helveticus as an active ingredient. Also disclosed is a visceral fat accumulation inhibitor or a food or beverage for inhibiting the accumulation of a visceral fat, which comprises a culture or cell of Lactobacillus helveticus as an active ingredient.

Abstract: A muscle-building agent comprising a whey protein hydrolyzate having a molecular weight distribution of 10 kDa or less, a main peak of 200 Da to 3 kDa, an average peptide length (APL) of 2 to 8, a free amino acid content of 20% or less, and antigenicity equal to or less than 1/100,000th of that of ?-lactoglobulin is provided. The whey protein hydrolyzate is very safe, exhibits high transparency when dissolved in water, has low bitterness, can be used for an arbitrary product, and exhibits a muscle-building effect.
