Foodstuffs – Determination of nitrate and/or nitrite content – Part 4: Ion-exchange chromatographic (IC) method for the determination of nitrate and nitrite content of meat products
This European Standard specifies an ion-exchange chromatographic method for the determination of the nitrate and nitrite contents of meat products and has been validated for different meat products with a nitrate content of 50 mg/kg to 300 mg/kg as nitrate ion and a nitrite content of approximately 40 mg/kg as nitrite ion.NOTE Validation data obtained from interlaboratory studies show that this method may also be applied to the determination of nitrate in vegetables and baby food, see [1], [2]. Furthermore, the method may be applied for the determination of nitrite in meat products having a nitrite content greater than 40 mg/kg.
