Welcome to the Biopolymers Interactions Assemblages (BIA) laboratory

Against a backdrop of demographic and food transitions, environmental and energy constraints, and growing awareness of the links between these factors and public health, the Biopolymers Interactions Assemblages (BIA) Unit, part of the TRANSFORM department of the new INRAE Institute, is focusing its research project on the sustainable transformation of agricultural resources and plant biomass. The aim is to integrate the entire processing chain for these resources, from their construction to their deconstruction during their final use.

Objectives

Bioresources are renewable sources of biomolecules (phenols, lipids, etc.), biopolymers (proteins, hemicelluloses, cellulose, lignins, polyphenols), supramolecular assemblies (aggregates, micelles, crystals, etc.), as well as organs and tissues (grains and seeds, cuticles, plant walls). These resources have been used by mankind since the dawn of time for food, energy production and as materials. Today, we are facing new challenges linked to the demographic, climatic and environmental context.

The sustainable and optimised use of these resources requires in-depth knowledge of their compositions, structures and architectures, as well as how they evolve during the transformation of raw materials into usable products.

The Biopolymers Interactions Assemblies (BIA) unit works with those involved in bioresource production to study the biological mechanisms that influence the quality of bioresources. At the heart of its expertise, BIA analyses the evolution of compositions and structures via fractionation, the impact of processes or formulation, and assesses product functionalities, both in technological terms and in terms of their environmental and human health impacts.

Through its research, BIA contributes to a more sustainable use of natural resources, by participating in the design of foods in relation to their impact on health and of bio-based materials while integrating the entire life cycle.
