Wheat malt intended for use in the production of beer
Prediction of the extract content and predetermination of the processability and value of a lot of barley for brewing purposes
The behavior of barley during the malting process, which is intended for large-scale malt production, must be known.
MEBAK approved and adopted a micromalting procedure on 6 April 1971 as a standard method for predicting the extract content and for determining the suitability of barley varieties for malting. In 2003, MEBAK shortened the procedure by one day for a total of six days for vegetative growth (steeping and germination), the same length of time as the EBC procedure.
This method describes how to determine the mycological status of a lot of barley as part of visual and manual inspections.
Kernels with a visually recognizable fungal infection is distinguished primarily by a black but at times pinkish red (barley) or white (wheat) discoloration over part or all of its surface. Pinkish red or white kernels indicate an infection by a species of Fusarium.
This method describes how to determine whether a lot of barley or wheat is contaminated with Fusarium graminearum using mannitol agar.
Fusarium graminearum contamination in barley or wheat can be visually determined with the naked eye after three to five days of incubation on mannitol agar.
Fusarium culmorum contamination in barley or wheat can be visually determined with the naked eye after three to five days of incubation on mannitol agar to which malachite green has been added.
This method describes how to classify barley according to size using a laboratory sieving machine.
Barley intended for the production of malt is to be evaluated on the basis of the characteristics described below.
A barley sample is classified into fractions according to kernel size in a sieving machine containing three sieves with defined slot widths.
