ISO 20938:2008 specifies a method for the determination of moisture content in instant coffee by the Karl Fischer titration method, suitable for use as a reference method.
Abstract
Overview
ISO 20938:2008 specifies a reference method for determining using the . The standard defines the principle, required reagents and apparatus, sample preparation, titration procedure and calculation of moisture (expressed as percentage mass fraction). It is intended for use as a laboratory reference method for accurate moisture analysis in spray‑dried, agglomerated (granules) and freeze‑dried instant coffee.
