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

4.7.1 - General Aerobic Count in Acid and Caustic Recovery Systems

Quantitative evaluation of aerobic and facultative microorganisms in caustic or acid solutions of CIP recovery systems. Both acid and caustic recovery systems can become contaminated and it is recommended that tanks used to recover acid or caustic should be regularly assessed for this reason. Descriptors: general aerobic count in acid and caustic recovery systems.

4.7.1 - Colour of Malt. Spectrophotometric Method (RM)

The determination of the colour of worts produced from a laboratory extract of malt by a spectrophotometric method. This method has been adopted as the reference method in preference to the more subjective visual method.

It is necessary to use EBC Methods 4.5.1 or 4.6.1 and 4.6.2

The efficacy of chemical disinfectants should preferably be tested according to the approved methods in the guidelines of the European Committee for Standardisation (CEN). Descriptors: efficacy of disinfectants, bovine albumin, standardised hard water, European standards for testing chemical disinfectants, microbiological evaluation of the efficacy of sterilants and biocides.

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.
