Milk and milk products — Determination of nitrate content — Method by enzymatic reduction and molecular-absorption spectrometry after Griess reaction - First Edition
N 20541
Annotation
This International Standard specifies a method for the determination of the nitrate content of milk and milk products by molecular-absorption spectrometry after Griess reaction (preceded by enzymatic reduction).
The method is, in particular, applicable to whole, partly skimmed, skimmed and dried milk, hard, semi-hard and soft cheeses, processed cheese, whey cheese, caseins, caseinates, dried whey and milk protein concentrates.
The method can be used at contents corresponding to a measured concentration in the sample solution (with blank subtracted) of more than 0,2 mg/l.

Молоко и молочные продукты — Определение содержания нитрата — Метод ферментативным сокращением и спектрометрией молекулярного поглощения после реакции Griess - Первый Выпуск
Этот Международный стандарт определяет метод для определения содержания нитрата молока и молочных продуктов спектрометрией молекулярного поглощения после реакции Griess (предшествовавший ферментативным сокращением).
