    摘要: Barley based beverages are produced in large quantities, employing highly energy consuming methods, for example in the malting and brewhouse facilities for kiln drying and wort boiling operations, respectively. The present invention relates to energy saving methods for preparing barley based beverages, as well as to barley plants useful in such methods. In particular, the invention describes barley plants with combined traits of null-lipoxygenase-1 (null-LOX-1), null-lipoxygenase-2 (null-LOX-2) and null-S-adenosylmethionine:methionine S-methyltransferase in one plant, which is particularly useful for energy saving methods to prepare barley based beverages, such as beer.

    摘要: According to the invention, there is provided barley with total loss of functional lipoxygenase (LOX)-1 and LOX-2 enzymes, and plant products produced thereof, such as malt manufactured by using barley kernels defective in the synthesis of the fatty acid-dioxygenating enzymes LOX-1 and LOX-2. Said enzymes account for the principal activities related to dioxygenation of linoleic acid into 9- and 13-hydroperoxy octadecadienoic acid, respectively. 9-Hydroperoxy octadecadienoic acid represents a LOX pathway metabolite, which—through further enzymatic or spontaneous reactions—may lead to the appearance of trans-2-nonenal (T2N). The invention enables brewers to produce a beer having insignificant levels of stale, T2N-specific off-flavors, even after prolonged storage of the beverage.
