Molnar, H.
This paper is dealing with the investigations of beer production by the application of unmalted raw material (surrogate) - native corn as the partial substitute for malt in grist. This substitute was differently treated: 1) thermal decomposition, 2) hydrothermic decomposition i.e. extruding. Native corn prepared by the mentioned methods - were added in experiments as the substitute for malt: 0, 20, 40, 50 and 60% in grist without the addition of egzogenic enzymes. The application of native corn in quantities from 20 to 40% in grist, gives good malt and beer production in laboratory. Quantities over 60% makes the technological procedure more difficult to get beer and gives beer with organoleptic characteristic. Application hydrothermic decomposed corn in quantities from 20 to 50% in grist gives good malt and beer with better characteristic, without strange taste and smell. Extruding procedure for substitute preparation indicated the highest savings in time necessary for boiling wort effecting positively on the increased capacity of brew house and simplification of the procedure.
