The development of a biorefining process acknowledges the feedstock characterization as it can often dictate the process technology. The maturity stages of agricultural feedstocks also have the potential for altering the process conditions. Thus, the variability of growth stages at 4-6 leaf, flowering, milk and soft dough were assessed for use of immature cereal crops in a green biomass biorefinery. Hence, the primary objective of this project was to evaluate the composition of green biomass at different harvest stages. Four varieties of triticale, two wheat varieties and two rye varieties were analyzed for starch, protein, phenols, fatty acids and sterols. To further characterize the feedstocks, an alternate extraction strategy was explored based on solvent polarity. It was found that for triticale varieties, the milk to soft dough harvest stages showed a decrease in proteins and phenols content and an increase in starch content. This could potentially provide benefit to organic acid production through fermentation. / Bioresource and Food Engineering
