Abstract
Lipid oxidation products are strongly believed to cause paper-like
off-flavours in beer. However, by adjusting process conditions and choosing
proper raw-materials unwanted changes can be minimised. This work gives new,
basic information about lipid reactivity during wort production and points out
the importance of raw-material properties, including lipase and LOX activity,
lipid composition, and antioxidativity. Depending on the raw-materials,
different amounts of lipids reacted during wort production and could develop
oxidised lipid compounds. By choice of raw-materials the distribution of
lipids between wort and spent grains, and boiled wort and trub could be
adjusted. Controlled lipid distribution enables the production of beer with
higher flavour stability.
