The change in viscosity of a mash of finely ground malt and water, with increasing temperature, was studied with a Brabender-Viscograph. A peak-shaped viscogram was obtained, the shape being characteristic of malt. The size of the peak differed considerably in different malt samples tested. A method for viscographic analysis of malt was devised. Examination of the relation between the viscogram and the properties of malt showed that the viscosity just before gelatinization, the maximum viscosity, the final viscosity and the peak area of the viscogram of the mash were correlated with various quality factors of the malt.The viscogram can be obtained rapidly and easily and so seems to offer a useful method for evaluation of the quality of malt.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
