摘要
目前国际标准对红葡萄酒中人工合成色素定性鉴定未作明确规定,葡萄酒中的自然色素在不同pH环境中显色作用不同,而人工色素无此现象,以及氧化剂对不同性质的色素具有明显影响,据此对含人工色素的葡萄酒定性鉴定,再进行定量检测,可达到降低检测成本,提高检测效率的目的。
There are no clear international standards of synthetic pigment in claret up to the present. The natural pigment in claret has different color under different pH values but synthetic pigment does not have such properties. Oxidizer has great effects on both natural pigment and synthetic pigment. Accordingly, we can make qualitative identification of claret containing synthetic pigment, and then make quantitative analysis, which could reduce detection cost and increase detection efficiency.
