Richard Hartel

Professor Hartel is internationally-recognized for his expertise in understanding phase transitions in foods. Phase transitions in foods play an important role in determining textural and physical properties of many food products. Understanding these phase transitions is critical to proper design, development and control of many food processes. In particular, Professor Hartel studies crystallization of ice (freeze concentration, recrystallization in frozen desserts), sugars (refining, confectionery applications) and lipids (milk fat fractionation, mixed lipid crystallization in chocolates and confections) as well as glass transition events of importance to stability and shelf life of foods. This work involves fundamental understanding of the physical chemistry of these phase transitions, kinetics and applications of this understanding to real products. In general, Professor Hartel applies these principles to food products like ice cream, confections, chocolate and compound coatings, and dairy products.
