Journal Article
Ferrari-John, R., Katrib, J., Zerva, E., Davies, N., Cook, D. J., Dodds, C., & Kingman, S. (in press). Electromagnetic heating for industrial kilning of malt: a feasibility study. Food and Bioprocess Technology, https://doi.org/10.1007/s11947-016-1849-0

Industrial malting operations use ~800kWh/t of energy to produce the heat required to kiln malt. Electromagnetic heating technologies are suggested as a way to potentially improve the energy efficiency of the kilning processing. In this work, the pot...

Mashing with unmalted sorghum using a novel low temperature enzyme system: impacts of sorghum grain composition and microstructure (2016)
Journal Article
Holmes, C. P., Casey, J., & Cook, D. (2017). Mashing with unmalted sorghum using a novel low temperature enzyme system: impacts of sorghum grain composition and microstructure. Food Chemistry, 221, https://doi.org/10.1016/j.foodchem.2016.10.083

Brewing lager beers from unmalted sorghum traditionally requires the use of high temperature mashing and exogenous enzymes to ensure adequate starch conversion. Here, a novel low-temperature mashing system is compared to a more traditional mash in te...

Bioethanol production from brewers spent grains using a fungal consolidated bioprocessing (CBP) approach (2016)
Journal Article
Wilkinson, S., Smart, K. A., James, S., & Cook, D. J. (2017). Bioethanol production from brewers spent grains using a fungal consolidated bioprocessing (CBP) approach. BioEnergy Research, 10(1), 146-157. https://doi.org/10.1007/s12155-016-9782-7

Production of bioethanol from brewers spent grains (BSG) using consolidated bioprocessing (CBP) is reported. Each CBP system consists of a primary filamentous fungal species, which secretes the enzymes required to deconstruct biomass, paired with a s...
