Abstract

Husk, which doesn’t adhere properly or breaks easily, causes economic and processing problems. There are, however, no generally acknowledged methods to measure husk quality. Chemical and microscopic analyses showed that the physical structure rather than chemical composition determines husk adherence. Mechanical and visual methods were developed. They were used to evaluate husk damage from harvest through the entire logistic and production chain to final malt. Barleys originating from different countries and crop years were also analysed. The results confirmed that both variety and growing conditions affect husk quality. The generally observed breakage at distal end did not affect malting behaviour. The methods can be used in barley breeding and quality control.
