Education and Employment Background

Alejandro Marangoni received his PhD in Food Chemistry from the University of Guelph. He completed post-doctoral training in the Department of Biochemistry before joining the Department of Food Science faculty in 1991.

Research Themes

Prof. Marangoni’s research works toward the development of novel structured emulsions to use in place of trans fats, saturated fats, and palm oil in foods. Other innovations in this area include the development of oil gels, or oleogels, and using physical structuring to modify the physiological effect of fats and oils. With this research he hopes to create healthier alternatives to high fat foods, without losing the desired flavor or texture. These alternatives may also have applications in improving the health characteristics of cosmetic products, decreasing the environmental impact of the use of lubricants and grease, and improving the sustainability of food production. His research team is also working on improving plant-based meat analogues.

His research focuses on the following major themes:

  1. Investigating the relationship between structure and macroscopic properties of food materials. This research will allow development of novel strategies for the functional replacement of trans and saturated fats in food products such as cheese, processed meat, and many baking products. These strategies can also be used to produce petroleum-free cosmetics.
  2. Studying the factors that control the self-assembly of lipid materials. This research will provide a better understanding of how oleogels form at the nanoscale and allow the creation of new oleogels for applications in food and cosmetics.
  3. Creating fibrous protein structures that mimic meat protein, without using extruders. The goal of this research is to find ways of producing plant-based meat analogues that use less energy and have less carbon footprint than extrusion.
  4. Investigating a series of plant-based proteins for their ability to self-assemble to form fibers, so that they can form an ideal food matrix with other bulk proteins and ingredients. This will simplify the processing of these foods while creating a taste and mouth-feel similar to meat.
