Metal significance in brewing - concentration changes during wort boiling.Peer-reviewed article

V. KELLNER, P. ČEJKA, F. FRANTÍK, L. VESELÝ

Changes in K, Na, Mg, Ca, Fe, Cu, Zn and Mn concentration during boiling procedure (from raw-materials to wort) were observed in experiments performed on a pilot plant scale. It was found that in majority of observed elements, except those of K, Na and partially those of ca and Mg, only a very low fraction (below 10 %) came from malt to wort and hopped wort. The majority of these elements was precipitated in spent grains, further fraction then in cooler sludge. The article forms the first part of complex studies that are focused and a significance of the individual element in brewing and malting.
