According to the invention, there is provided barley-derived beverages characterized by notably reduced levels of both dimethyl sulfide (DMS) and/or its precursor S-methyl-L-methionine (SMM), or lacking said compounds. In addition, the invention relates to methods for producing the above-mentioned beverages&#x2014;and also to barley plants useful in the preparation of such beverages, as well as other plant products prepared from said plants. Utilization of the invention clears the way for making improved production procedures of beverages with improved taste profiles, and promises also for notable reductions in the thermal energy input for production of beer.

Barley and malt-derived beverages with low DMS level

According to the invention, there is provided null-LOX-1 barley and plant products produced thereof, such as malt manufactured by using barley kernels defective in synthesis of the fatty acid-converting enzyme lipoxygenase-1. Said enzyme accounts for the principal activity related to conversion of linoleic acid into 9-hydroperoxy octadecadienoic acid, a lipoxygenase pathway metabolite, which&#x2014;through further enzymatic or spontaneous reactions&#x2014;may lead to the appearance of trans-2-nonenal. The invention enables brewers to produce a beer devoid of detectable trans-2-nonenal-specific off-flavors, even after prolonged storage of the beverage.
