Development of image analysis methods to evaluate barley / malt grain size

Detalhes bibliográficos
Resumo:It is known that the barley / malt grain size is an important factor regarding the uniformity of malting process and hence the brewery process. For that purpose an image processing and analysis system was built for the evaluation of grain / malt size, on the ImageJ public domain platform. A programme was developed for the barley / malt images treatment and determination of several morphological parameters as well as the grain size distribution. The results showed that for the Prestige and Scarlett barley varieties good correlations could be obtained between the standard weight distribution and the proposed image analysis method. For the Esterel malt and barley as well as for the Nevada barley reasonable to good correlations were also obtained upon the introduction of a density correction factor.
