During food processing/stabilization, many physical and biochemical modifications of constituents take place. These changes are available in structural or state changes beyond the critical concentration, and induce modifications in the performance of operations. Therefore process control involves making progress on fundamental issues of major interest in the field of dairy processing in order to move towards more targeted products and safer and eco-aware processes.

Our objective

Studies carried out by Spray-drying - Concentrated Matrices - Functionalities (SMCF) team aim to master manufacturing process and control the technological and nutritional properties of a wide range of dry ingredients (protein isolates, ingredients incorporating pre- and probiotics, etc.) implemented in products increasingly specialized (seniors, sportsmen, infants, etc.). Our main concern is to understand how the management of concentration / destabilization operations (evaporation-spray-drying / rehydration) affects the behavior and properties of the ingredients and, in return, how their features and properties modify performances and environmental impact of processes.

Our strategies

Our works are conducted at multiscales, from molecular to macroscopic by combining studies on both model and real systems, in order to:

  • Identify, quantify and model physico-chemical mechanisms involved in state transitions undergone by dairy matrices during the concentration / destabilization processes 
  • Establish general rules to select appropriately designed processes, technological trajectories in dairy and cheese processing in order to control and optimize properties of these matrices
  • Capitalize on knowledge to put forward technological schemes of concentration and drying  to design more efficient, innovative and eco-aware processes with the manufacture of products of high qualities.

Skills & Expertise

Our research brings together a network of experts in:

  • Process engineering
  • Colloïds science
  • Proteins and lipids biochemistry
  • Dairy and cheese processing.
