Understanding LOX

Breeding, malting, and brewing strategies to preserve beer freshness

Among the different malt-derived pathways for beer staling, the lipoxygenase (LOX)-mediated oxidation of unsaturated fatty acids is a better understood mechanism. By controlling the production of LOX in malt, brewers can benefit through the low production of trans-2-nonenal (T2N) in the final beer. This seminar sheds light on the role of malt LOX in the manifestation of papery/cardboard notes in beer during storage, and the mitigation of LOX formation in malt from barley breeding to malting processes that are in practice in the industry. 

This free webinar is co-hosted by the Brewers Association and American Malting Barley Association but registration is required. 

Speakers:

Xiang S. Yin | Supply-Chain Quality Specialist, Prairie Malt/Boortmalt USA
Bio: Xiang S. Yin works at Prairie Malt/Boortmalt USA on supply chain quality. He serviced the industry previously in various technical leadership roles at Rahr Malting, SABMiller and Cargill Malt, respectively. He is a past president of ASBC, and is a fellow of the CIBD. Xiang is on the editorial boards of JASBC and MBAA TQ, and has authored the  ASBC book MALT, the first of the series for Practical Brewing Science. He currently serves as an affiliated graduate  faculty member at NDSU and adjunct professor at Univ of Manitoba. He holds a PhD from the Heriot-Watt  University and taught fermentation technology earlier in the Jiangnan University, China. He has a sixth dan black  belt for taekwondo.

Aaron Beattie | Associate Professor, Ministry of Agriculture Strategic Research Program (SRP) Chair in Barley and Oat Breeding and Genetics, University of Saskatchewan
Bio: Aaron Beattie is a professor and barley breeder at the Crop Development Centre, University of Saskatchewan, position he has held since 2010. His breeding program focusses primarily on two-row malting and feed barley, but  also devotes effort towards hulless malting and food barley. The CDC barley breeding program has released 10  varieties over the past decade, including the hulled malting varieties CDC Churchill, CDC Fraser and CDC Goldstar,  and the hulless malting varieties CDC Armstrong and CDC Pristine. He is a former Canadian Malting Barley Technical Centre and Barley Council of Canada board member, and is currently the chair of the Prairie Recommending  Committee for Oat and Barley Agronomy Committee.
