4.2 - Moisture Content of Malt

The determination of the moisture content of all malts by loss in mass on drying under specified conditions. The ISO Method for moisture content of grain (ISO 712-1985) which is used for barley (EBC Method 3.2) must not be used for malt as the conditions of drying are such that chemical condensations occur in which water is formed as a product of reaction.

4.6.1 - Hot Water Extract of Malt: Constant Temperature Mash

The determination of Hot Water Extract of ale, lager and distilling malts using a constant temperature infusion mashing procedure of a coarsely ground sample (0,7 mm). The wort produced by this mashing procedure is used for ancillary analyses, such as the determination of saccharification rate, colour, viscosity of wort, soluble nitrogen content, free amino nitrogen content, fermentability, and pH. Fine/coarse difference may be derived by simultaneously determining the Hot Water Extract of a more finely ground grist (0,2 mm) from a second test portion of the malt sample.

It is necessary to use EBC Methods 1.1 and 4.1

4.10 - Free Amino Nitrogen of Malt by Spectrophotometry

The determination of the free amino nitrogen content of malt using colorimetry with ninhydrin. The method gives an estimate of amino acids, ammonia and, in addition, the terminal nitrogen groups of peptides and proteins. Proline is partially estimated at the wavelength used. The method is not specific for α-­amino nitrogen since γ-amino butyric acid, which is present in malt worts, also gives a colour reaction with ninhydrin.
