Abstract

La présente invention aborde le problème de la réduction de l'oxygène dissous dans l'eau par l'intermédiaire d'un moyen simple tout en utilisant un matériau qui peut être utilisé dans des aliments et des boissons. Un agent de réduction d'oxygène dissous contenant des mélanoïdines, en particulier des aminoréductones, est utilisé. La teneur des aminoréductons est calculée par une mesure de réduction de XTT, et l'oxygène dissous est réduit par ajout dudit agent de réduction d'oxygène dissous à de l'eau de telle sorte que la teneur en aminoréductones devienne supérieure ou égale à 10 µM. De plus, en ajoutant un agent d'amélioration de pH et de l'acide ascorbique, l'effet de réduction de l'oxygène dissous peut être remarquablement augmenté. En utilisant l'eau dans laquelle l'oxygène dissous est réduit par l'intermédiaire du moyen selon la présente invention, une boisson ou un aliment traité ayant un arôme, une teinte, ou les fonctions physiologiques de matériaux à mélanger en son sein peut être produit.
