Develop knowledge to produce healthier foods. Specializing in the fermentation of foods with lactic acid bacteria, I work in the manufacture of yogurt, cheese and fermented vegetables. In addition, I am exploring technologies that would allow us to produce and add probiotic cultures to foods: fruit juices, dairy products, cereal products. The technologies used are microencapsulation and fermentation with immobilized cells.

Current research and/or projects

  • Addition of probiotic bacteria in dairy products, meats and soy beverages, with a focus on high protein products.
  • Add probiotics to feeds or foods to fight intestinal infection by rotaviruses.
  • Effect of microorganisms on the texture of cheeses.

Research and/or project statements

Probiotic cultures are bacteria which are added to foods, in the specific goal to make them healthier. However, these bacteria are very sensitive and tend to die during food processing steps or during storage. We therefore develop fermentation or microencapsulation technologies that aim to improve their survival in food and thus help provide the health benefits. Our actions also aim to protect probiotics after consuming the food, so that they can reach the intestines in a living state.

The texture of the cheese is influenced, in particular, by fermentation technology, the season of milk production and contaminating bacteria. Considering these parameters, we study the effect of antimicrobial proteins, which are naturally present in milk, on the development of desirable and undesirable bacteria during cheese ripening.

Some probiotic bacteria have antiviral properties. We are trying to discover the species that would specifically fight rotavirus, which causes diarrhea in pigs and humans.
