Abstract:
A method for producing a high-zinc-content yeast extract, including extracting the high-zinc-content yeast extract by suspending zinc-containing yeast into a solution containing a carboxylic acid, a carboxylic acid salt, or both thereof to thereby obtain a suspension liquid, and separating a solid component and a liquid component of the suspension liquid; the high-zinc-content yeast extract; food; and an agent for maintaining and restoring a green color of vegetables.
Abstract:
A method for producing a copper-containing yeast extract, comprising: extracting the copper-containing yeast extract by suspending copper-containing yeast into a solution containing an amino acid or a salt thereof to obtain a suspension, and separating a solid component and a liquid component of the suspension, wherein the amino acid or the salt thereof is water-soluble; a copper-containing yeast extract; food; and?an agent for maintaining and restoring a green color of vegetables.
Abstract:
A method for producing a zinc-rich yeast extract, the method comprising an extraction step for suspending a yeast containing zinc in a solution including carboxylic acid and/or carboxylic acid salt, and separating the solid component and liquid component of the resulting suspension; a zinc-rich yeast extract; and a green-retaining/-restoring agent for food and vegetables.
Abstract:
A method for assaying melanotransferrin in association with arthritis and a reagent and a kit to be used in this assay method. The above method comprises: i) measuring the melanotransferrin concentration in a biological sample; and ii) judging as arthritis in case where the melanotransferrin concentration in the biological sample is significantly higher than in non-arthritis biological samples.
Abstract:

Abstract:
A new method of rapidly analyzing plural substances in the presence of biological catalyzers is disclosed. The method is practiced by way of the steps of injecting both pH buffer solution and specimen into a reaction cell, successively adding a plurality of enzymes to induce uptake reaction of dissolved oxygen, causing the plurality of substances to be subjected to selective oxidation in the stepwise manner, obtaining a stepdown curve of dissolved oxygen by automatically recording the oxidative process by means of a dissolved oxygen sensor, qualitatively determining each of the substances with reference to the kind of added enzymes and the order of their addition and quantitatively determining the same with reference to the extent of decrease in dissolved oxygen. Typically, oxidation of the substances is carried out by way of two or three or further more steps. The reaction cell for performing the method is equipped with a dissolved oxygen sensor on the one side wall and its upper portion is airtightly closed with a plug through which a fine bore is formed for the purpose of supply of buffer solution, specimen and enzymes.
Abstract:
Provided is a method for manufacturing a yeast extract containing copper includes an extraction step wherein yeast containing copper is suspended in a solution that contains an amino acid or a salt thereof and the solid components and liquid components of the suspension obtained are separated with the amino acid or salt thereof being water-soluble. Also provided are a yeast extract containing copper, a food product, and a green color preserving and restoring agent for vegetables.
