Abstract

The respiration kinetics of Aspergillus oryzae on different varieties of whole wheat kernels were studied. Six wheat varieties were pretreated in two different ways. Five of the six substrates fermented similarly and independently of the pretreatment method. However, pretreatment affected fermentation of one variety of soft wheat (Apollo). T 2 1H-NMR imaging of the water inside the kernels showed a change in water binding inside the kernels when a different pretreatment strategy was used. Differences in free sugar or amino acid content or in kernel stiffness were not significant.
