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—through further enzymatic or spontaneous reactions—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.

An adaptive information compression system and method conserves information bandwidth or storage space by compressing underutilized information present in a wide-band signal into a much narrower maximum utilized information band signal. This is achieved by obtaining a spectral concentration map of an input wide-band signal by transforming the wide-band signal into the frequency domain and de-selecting the data space where there is substantially little spectral activity. A narrow-band signal is created by reformatting the remaining data space into a contiguous narrow-band signal. The original time-domain image of the data, which has the inactive spectra removed, is reconstructed from the narrow-band signal, thus allowing the total time-domain bandwidth to be significantly less than the original.
