    • The present invention provides a method of suppressing fading of a tar colorant. More specifically, the present invention provides a method of suppressing a tar colorant fading phenomenon that occurs specifically in compositions containing (a) the tar colorant, and (b) at least one of reducing sugars, ascorbic acid compounds, or metals. This method can be attained by mixing (c) at least one selected from the group consisting of isoquercitrin, enzymatically modified isoquercitrin, rutin, enzymatically modified rutin, Chinese bayberry extract, and rosemary extract into such a composition, thus making the component (a), the component (b) and the component (c) coexist. The present invention further provides a composition for which fading of a tar colorant is suppressed using the above method, more specifically a composition containing at least one of reducing sugars, ascorbic acid compounds, or metals in addition to the tar colorant.
    • 本发明提供抑制焦油着色剂褪色的方法。 更具体地说,本发明提供一种抑制在含有(a)焦油着色剂的组合物中具体发生的焦油着色剂褪色现象的方法,和(b)还原糖,抗坏血酸化合物或金属中的至少一种。 该方法可以通过将(c)选自异槲皮素,酶促改性的异槲皮苷,芦丁,酶促改性芦丁,中国杨梅提取物和迷迭香提取物中的至少一种混合到这样的组合物中,从而使组分(a) ,组分(b)和组分(c)共存。 本发明还提供一种组合物,其中使用上述方法抑制焦油着色剂的褪色,更具体地说,除了焦油着色剂之外还包含含有还原糖,抗坏血酸化合物或金属中的至少一种的组合物。
