Milk and milk products — Determination of nitrate and nitrite contents — Part 3: Method using cadmium reduction and flow injection analysis with in-line dialysis (Routine method) 牛奶和奶制品——硝酸盐和亚硝酸盐含量的测定第3部分:镉还原法和在线透析流动注射分析法(常规法)
发布日期: 2004-02-02
ISO 14673-3 | IDF 189-3:2004规定了通过镉还原和流动注射分析(FIA)测定牛奶和奶制品中硝酸盐和亚硝酸盐含量的常规方法。该方法适用于不同年龄段的硬奶酪、半硬奶酪和软奶酪,以及加工奶酪。该方法的检测限分别为每千克0.5毫克硝酸根离子和每千克1.0毫克亚硝酸盐离子。 该方法也适用于乳清粉、奶粉和乳基婴儿食品。
ISO 14673-3|IDF 189-3:2004 specifies a routine method for the determination of the nitrate and nitrite contents of milk and milk products by cadmium reduction and flow injection analysis (FIA). The method is applicable to hard, semi-hard and soft cheeses of various ages, and processed cheese. The detection limits of the method are 0,5 mg of nitrate ions per kilogram and 1,0 mg of nitrite ions per kilogram, respectively. The method is also applicable to whey powder, milk powder and milk-based infant food.
