The husk content of barley intended for use in beer production should be known.
The husks are separated from the barley kernels through treatment with sodium hypochlorite. The husk content is determined by calculating the reduction in weight, (dry matter) resulting from the removal of the husks.
This method describes how to evaluate husk character as part of the visual and manual inspection of a lot of barley.
Barley intended for the production of malt is to be evaluated on the basis of the characteristics described below.
Visual assessment
Barley intended for the production of malt; therefore, the kernels are to be evaluated on the basis of the characteristics described below.
Visual assessment
This method describes how to determine the percentage of kernels with damaged husks in a lot of barley as part of visual and manual inspection.
Barley intended for the production of malt; therefore, the kernels are to be evaluated on the basis of the characteristics described below.
Visual assessment
Volumetric determination of the husk fraction
Grist from malt or adjuncts
The sieve analysis is performed on a sample of brewery grist of a known weight with a shaking device containing a set of sieves (according to DIN ISO 3310-1 specifications or a Pfungstädter plansifter sieving device). The material retained on sieve 1 is then poured into a 500 ml graduated cylinder and the volume (without shaking) is read on the graduated cylinder.
This method describes how to evaluate the degree of contamination or the purity of malt as part a manual inspection procedure.
Malt intended for use in beer brewing or elsewhere in the food industry.
Visual examination of malt for foreign objects. Refer to the Sieving Test for Malt (R-200.08.011).
