Dough mixing and processing conditions play an important role affecting dough behavior during subsequent steps of bread making, considered important for final texture, sensory and nutritional quality of baked products. These changes can be monitored by dough thermo-rheological properties, which are functions of wheat flour dough composition and processing conditions. Dough behavior during mixing and fermentation has successfully been modelled for a single formulation and wheat variety, and still needs to be modelled in order to extend the existing Knowledge Based System (KBS AsCoPain), also including further steps, shaping and baking. This project has been designed to assemble the existing knowledge on available models and to develop new Basic Knowledge Models (BKM) to control dough formation and baking. The knowledge integrated from professional expertise, scientific literature and experimental results are used to improve the modelling of bread making process. Experimental aspects involve the structural analysis and determination of dough behavior for various recipes of realistic cereal foods during mixing, shaping, fermentation and baking, by implementing existing and developing novel scientific methods, especially regarding adhesive properties. These results will be compared to those obtained from the simulation of fermentation, shaping and baking, using AsCoPain in order to extend its application to different bakery products. The project will also contribute significantly to extend the industrial know-how and professional knowledge in order to transfer and integrate the innovative tools for the uplift of food industries.
I am working as Assistant Professor at National Institute of Food Science and Technology, University of Agriculture Faisalabad, Pakistan along with current post-doctoral position at INRA de Nantes. I have acquired master (2007) and PhD (2010) in Food Science from University of Nantes, France and graduation from University of Agriculture Faisalabad, Pakistan. My specialty is on processing, textural and nutritional aspects of different cereals. During my postgraduate studies, I have performed my research on solvent retention capacities of different wheat varieties in relation to their cookie making quality. Dough behavior and functional properties of wheat flour dough liquor were thoroughly explored during master research at INRA, Nantes, France in 2007. While continuing the same domain during doctoral studies French bread making process was investigated where the steps of mixing and fermentation were successfully modelled. A specific protocol was developed to study the dough evolution during fermentation by using different mixing and formulation conditions. I have been also invited to talk at various international conferences in Australia, Turkey, USA and The Netherlands.
