Emerging technologies
The Emerging Technologies laboratory, led by Professor Federico Gómez Galindo, has been dedicated to the study of electrotechnologies and vacuum impregnation for over 15 years. It stands as the only laboratory in Sweden actively advancing knowledge in this field, particularly in relation to food applications.
The activities in the group covers the developing of electropermeabilization protocols for the complex structures of plant tissues. The group’s research is focused on identifying optimal mechanisms for the impregnation of functional molecules into edible plant tissues, as well as improving the understanding of consequences of processing-induced metabolic responses.
Emphasis is placed on the use of these technologies to enhance freezing tolerance, improve the quality of aromatic dried herbs, and extend the shelf life of fresh, packed vegetables. Exploring the metabolic responses of microorganisms to the application of an electric field opens possibilities for optimizing fermentation processes. Applying electrotechnologies and vacuum impregnation to seeds, seedlings, and plant cuttings can improve agricultural productivity and make crops more resilient.
Fermentation of plant-based foods
Food fermentation is a traditional and versatile processing technique that not only enhances the shelf life and flavor of foods but also plays a crucial role in improving their nutritional profile. In our research group, we focus on fermentation to reduce ‘antinutritional compounds’ in plant-based foods. We conduct research to understand how the antinutritional compounds such as phytic acid, lectins, and protease inhibitors, commonly found in various plant-based foods, interfere with the digestibility and absorption of macro and micronutrients.
Our expertise involves a deep understanding of the interactions between phytates and essential minerals like zinc and iron. We have great interest in investigating how different fermentation conditions, such as starter cultures, temperature, pH and time affect not only the bioavailability of nutrients but also the sensory characteristics of plant-based foods. Emphasis is also put on identification and characterization of selected new strains with potential to be used as starter cultures specifically for plant-based food, to develop new products based on side streams, improve safety, and enhance bioactive compounds.
