An antioxidant material of the present invention contains flavonoid aglycon and vitamin C. The flavonoid aglycon is eriodictyol and/or diosmetin obtained by treatment of a raw material containing flavonoid glycoside derived from lemons, limes, or sudachis to form the aglycones thereof. It is preferred that this antioxidant material be produced through a step of mixing the flavonoid aglycon and the vitamin C after the treatment to form the aglycones. The treatment to form the aglycones is glycosidase treatment using a β-glycosidase derived from a microorganism of the genus Aspergillus or Penicillium multicolor, or microbial fermentative treatment using a microorganism of the genus Aspergillus. An anti-deterioration agent and a food or beverage of the present invention contain the antioxidant material.
本发明的一种抗氧化剂材料含有黄酮苷元和维生素 C。黄酮苷元是通过处理从柠檬、酸橙或苏打树提取的含有黄酮苷元的原料以形成其苷元而获得的二碘酪醇(eriodictyol)和/或二锇醇(diosmetin)。这种抗氧化剂材料最好是在处理形成苷元后,通过将黄酮苷元和维生素 C 混合的步骤生产出来。形成苷元的处理方法是使用从曲霉属或多色青霉属微生物中提取的β-糖苷酶进行糖苷酶处理,或使用曲霉属微生物进行微生物发酵处理。本发明的抗变质剂和食品或饮料含有抗氧化材料。
