Problems solved by technology

However, deoxidizers using iron powder have the following disadvantages: because these deoxidizers react to metal detectors at the time of product inspection, they interfere with inspection; and because ingestion may have adverse consequences, there are safety aspects The problem
[0005] However, these organic deoxidizers cannot be used for perishable materials that tend to deteriorate when the temperature rises because these organic deoxidizers generate heat during the deoxidation process, resulting in an increase in the temperature of the article at the position in contact with the deoxidizer. foods or foods prone to loss of flavor, thereby limiting their use
In addition, compared with iron-based deoxidizers, these organic deoxidizers have poor deoxidation effect and are expensive. In addition, some deoxidizers also involve safety issues. Therefore, no exciting alternatives to iron-based materials have been found yet. satisfactory deoxidizer

Embodiment

[0092] The present invention is described more specifically below with reference to Examples, but the present invention is not limited thereto.

preparation example 1

[0095] Twenty millimoles of gallic acid were added to a stirred vessel in which 1L of 0.05M aqueous sodium carbonate solution (pH: 11.2) was housed, and under the condition that the air could flow freely and the surface of the reaction solution could fully contact the air, the reaction solution was heated at 25 °C vigorously stirred for 3 hours. Then, the reaction solution was freeze-dried to obtain 9.06 g of powder containing polyphenol derivatives (yield: 241% as gallic acid).

preparation example 2

[0097] 1600 ml of a 50 mM aqueous sodium carbonate solution was added to 80 g of dried green tea leaves, followed by vigorous stirring at 30° C. for one hour in a state where it could be exposed to air (pH of the reaction liquid: 8.7). After the reaction liquid was filtered, the filtrate was freeze-dried to obtain 51.8 g of powder containing polyphenol derivatives (based on dry tea leaves, yield: 64%).

Abstract

An oxygen absorber composition, characterized in that it comprises a polyphenol derivative prepared by reacting a polyphenol in an alkaline solvent in the co-presence of oxygen at a pH of 6.5 or higher and one selected from among water, a water-donating compound and a hygroscopic agent. The oxygen absorber composition is excellent in deoxidation effect, is free from the heat generation during the use thereof, can be subject to a metal detector, does not affect adversely a human body even in case it is eaten, and is friendly to a human being and the environment.

Description

technical field [0001] The present invention relates to deoxidizer compositions. Specifically, the present invention relates to a deoxidizer composition containing a polyphenol derivative and one selected from water, a water-supply compound, and a hygroscopic agent, wherein the polyphenol derivative can It is obtained by carrying out the reaction under the coexistence of solvent and oxygen molecule, and the minimum pH of 6.5 in the reaction process. Specifically, the present invention relates to a deoxidizer composition containing a polyphenol derivative and one selected from water, a water-supply compound, and a hygroscopic agent, wherein the polyphenol derivative can be It is obtained by using an alkaline solvent, the coexistence of oxygen molecules, and the pH during the reaction is at least 6.5; One of the deoxidizer compositions, wherein said polyphenol derivatives can be carried out by making specific polyphenols and amino acids use alkaline solvents, coexistence of ox...
