    摘要: PROBLEM TO BE SOLVED: To provide a method for preparing a barley plant with no or very little LOX-1 activity. SOLUTION: 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. The 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. COPYRIGHT: (C)2011,JPO&INPIT
