摘要

Brewing with unmalted barley can reduce the use of raw materials, thereby increasing the efficiency of the brewing process. However, unmalted barley contains several undesired components for brewing and has a low enzymatic activity. Pearling, an abrasive milling method, has been proposed as a pre-treatment for barley to remove some of its undesired components, while maintaining its beta-amylase activity. The potential of combining pearling with using barley/malt mixtures for brewing was studied. Filtration was performed either in a mash filter or in a lauter tun. The effects of the different barley/malt ratios, degree of pearling and two different filter types on compositional and quality parameters were assessed. It was concluded that a mash filter is optimal for this type of process, and a window of operation could be identified in which optimal use is made of the raw materials while maintaining the end product quality, judged on basis of four quality parameters.
