Until the beginning of the 20th
century, spelt was the predominant grain for bread production in
many regions, for example in southwestern Germany, and parts of
Switzerland and Austria (Escarnot et␣al., 2010). Since then, however,
wheat has largely replaced spelt. This is due to spelt’s lower
yield and its long strawwith a tendency to lodge, especially if levels
of nitrogen fertilizer applied are too high. Furthermore, as spelt is a
hulled grain, a dehulling step prior to milling is required (Schober
et␣al., 2006).
