A TCATA by modality approach to study the multisensory temporal profile of hop bitter and flavour products applied in lager (2021)
Journal Article
Dietz, C., Cook, D., Yang, Q., Wilson, C., & Ford, R. (2022). A TCATA by modality approach to study the multisensory temporal profile of hop bitter and flavour products applied in lager. Food Quality and Preference, 97, Article 104470. https://doi.org/10.1016/j.foodqual.2021.104470

Previous research suggested that iso-alpha-acids and hulupones add different bitterness profiles to beer and hop-derived volatiles modify temporal dimensions of bitterness qualities via cross-modal interactions. This research aimed to understand the... Read More about A TCATA by modality approach to study the multisensory temporal profile of hop bitter and flavour products applied in lager.

Bioethanol Production from UK Seaweeds: Investigating Variable Pre-treatment and Enzyme Hydrolysis Parameters (2019)

Characterisation of high molecular weight hop proanthocyanidins using Analytical Ultracentrifugation (2019)
Journal Article
Gadon, A., Linforth, R., Harding, S. E., & Cook, D. (2019). Characterisation of high molecular weight hop proanthocyanidins using Analytical Ultracentrifugation. Scientific Reports, 9(1), Article 12650. https://doi.org/10.1038/s41598-019-49171-4

We report the novel application of Analytical Ultracentrifugation (AUCF) to characterise the polymeric proanthocyanidin fraction of hops. Extraction of hop samples with 70% acetone (aq) followed by a C-18 Solid Phase Extraction yielded polyphenolic f...

Dry-hopping: the effects of temperature and hop variety on the bittering profiles and properties of resultant beers (2017)
Journal Article
Oladokun, O., James, S., Cowley, T., Smart, K., Hort, J., & Cook, D. (2017). Dry-hopping: the effects of temperature and hop variety on the bittering profiles and properties of resultant beers. Monatsschrift fur brauwissenschaft (Internet), 70(6),

This paper reports the effects of dry-hopping at 4 and 19 °C for a low alpha versus high alpha hop variety on the resulting profiles of non-volatile hop acids (humulinones, iso-a-acids, a-acids). In a dry-hopping study conducted over 2 weeks, we foun... Read More about Dry-hopping: the effects of temperature and hop variety on the bittering profiles and properties of resultant beers.

Complete acid-based hydrolysis assay for carbohydrate quantification in seaweed: a species-specific optimized approach (2017)
Journal Article

Perceived bitterness character of beer in relation to hop variety and the impact of hop aroma (2017)
Journal Article
Oladokun, O., James, S., Cowley, T., Dehrmann, F., Smart, K., Hort, J., & Cook, D. (2017). Perceived bitterness character of beer in relation to hop variety and the impact of hop aroma. Food Chemistry, 230, https://doi.org/10.1016/j.foodchem.2017.03.031

The impact of hop variety and hop aroma on perceived beer bitterness intensity and character was investigated using analytical and sensory methods. Beers made from malt extract were hopped with 3 distinctive hop varieties (Hersbrucker, East Kent Gold...
