No-time dough baking performance and mixing properties of Canadian Red Spring wheat cultivars using Canadian and Australian test procedures

Abstract

The mixing properties and baking performance of 17 Canada Western Red Spring wheat varieties and advanced breadwheat lines grown under the same environmental conditions have been assessed using Canadian and Australian test bake procedures with emphasis on no-time dough processes. Mixing times with the Australian rapid dough process (RDP) were considerably shorter than those obtained with the Canadian short process (CSP). However, a very high correlation was obtained for mixing time with the RDP and the CSP, indicating a similar ability to rank cultivar bake mixing requirements. Dough development times obtained from normal and high speed (180 rpm) farinograms and micro-mixograms were found to be poor predictors of CSP and RDP mixing time. Cultivars generally showed good to excellent baking performance with the 2 no-time procedures (RDP and CSP) and the Australian fermented dough procedure (FDP). High correlations and similar cultivar rankings were obtained for loaf volume and bread score with the CSP and FDP. However, no significant correlations and different cultivar rankings were obtained between RDP and CSP (or FDP), indicating that different quality properties may determine relative cultivar baking performance. These results also suggest that both no-time dough procedures may be required in breeder selection and quality monitoring programs to ensure superior breadwheat performance in domestic and export markets.
