The research carried out by the Processing & Agroresources unit mainly concerns the food and non-food valorization of agro-resources.
- The PETALES team will focus on characterizing agro-resources during their transformation and the impact of these transformations on intestinal homeostasis following early exposure.
- The VAM²IN team aims to study the structural/functional relationships of bio-sourced materials and products for their non-food use.
The scientific project
History of the unit
The Transformation and Agro-resources Unit is under the supervision of UniLaSalle, an engineering school in earth, life and environmental sciences, which was created in January 2016 from the merger between the Institut Polytechnique LaSalle in Beauvais and ESITPA in Rouen.
This Unit brings together the associate professor of the former EGEAL Unit (Gene Expression and Epigenetic Regulation by Food) in Beauvais, of axis 2 of the former AGRI'TERR Unit (Agro-ecology of Territories) in Rouen, and associate professor not previously associated with these former units (such as associate professors from the IUT of Béthune).
The unit's program focuses on the transformation and enhancement of the whole plant in a sustainable development perspective, from the study of the mechanisms of their construction to the study of their properties and functionalities during their final use, whether food and/or non-food. This unit is divided into 2 teams:
- PETALES team: Food processing and health effects;
- VAM²IN team: Non-food processing.
In the context of the use of agricultural raw materials in any agri-food process, the major transformation steps are likely to modify the molecular assemblies initially present by potentially generating new structures/assemblies and/or new compounds, absent from the product at the origin (i.e. neoformed compounds). All of these structures/molecules transit with or without modification through the digestive tract where they can exert their effects. Therefore, in order to apprehend these health effects within the framework of our scientific project, we have set up tools and methods aimed at :
1 - Characterize the agro-resources during their transformation
It is necessary to better take into account the quality of the initial raw materials selected but also to have a better control of the processes implemented. We evaluate the effects of heat treatments of the food matrix by characterizing and quantifying, mainly, the neoformed compounds appearing during this stage of processing:
- Characterize the potential impact of other types of food matrix transformation;
- Determine the factors of variability in the composition of unprocessed raw materials;
- To implement new dimensions of characterization allowing to apprehend changes in structure/conformation in the biopolymers present.
2 - To study the transformation of agro-resources on intestinal homeostasis following early exposure
The establishment and maintenance of intestinal homeostasis is a major element for health, and the positive and negative impact of consuming food, whether or not it has been processed, is a subject of study by our team. We are therefore evaluating the impact of assemblies resulting from processing and/or newly formed compounds on the establishment and maintenance of intestinal homeostasis. In this framework, the understanding of biological effects, molecular and cellular mechanics and the measurement of their potential impacts are based on the implementation of in vivo and in vitro models.
We focus on :
- Evaluate the impact of thermal and/or athermal transformation processes on molecular/molecular assemblies and their technological, organoleptic, sanitary and nutritional functionalities;
- Determine the origin and the impact of the variability of raw materials on the modifications observed during the transformation process;
- Establish the conditions for these molecules to affect the behavior of the different cells present in the intestinal sphere (viability test, growth, differentiation, gene expression, expression of epigenetic markers on cultures and co-cultures of cells in vitro);
- Estimate the impact of these molecules on intestinal homeostasis (animal models, characterization of physiological and molecular responses to exposure to the molecules studied).
Today, manufacturers are being encouraged to develop innovative materials that are more respectful of the environment and health, in a constrained economic and regulatory context. To meet these expectations, the use of agricultural by-products as vegetable raw materials is an interesting alternative due to their abundance and renewable nature. In this context, the team contributes to the valorisation of the cultivated plant within the framework of an integrated approach for the development of territories. The approach targets the non-food valorization of agro-resources through their transformation into materials and the production of molecules of interest for later applications, within innovative sectors to strengthen the development of the bio-economy based on the skills of the newly formed team and its partners.
1 - Construction and functionalization of new bio-sourced materials
The research activities carried out contribute to the understanding of the assembly mechanisms of biopolymers extracted from agricultural resources and co-products, involved in the material development processes. The objective is to control the structure, functionalities and durability of the materials by exploiting the intrinsic specificities of biopolymers and by integrating new technologies (extrusion, RMX, steam injection compression, ozonation...) in processes for the elaboration of assemblies specific to these bio-sourced materials. The interactions between constituents and interfaces are key points in the understanding of these new assemblies (structure/properties relationship).
We focus particularly on :
- the role of the composition and structure of agro-resources in the characteristics of agro-materials after their implementation ;
- the impact of treatment processes and intrinsic properties of plant raw materials on molecular assemblies and their functionalities (chemical and physico-chemical interactions, physical performance and preferential affinities).
These experimental approaches will be associated with statistical modelling work.
2 - Deconstruction of agro-resources for the production of bio-sourced products
This research aims to better characterize and study the deconstruction phenomena of the different fractions (native and/or transformed polymeric assemblies) of plant biomass in order to control and optimize in particular the production of energy and/or molecules of interest such as synthons (reaction intermediates for green chemistry reactions).
The research work aims to propose the elucidation of the link between the interactions of the structural properties of lignocellulosic biomass and its ability to deconstruct by means of high-performance pre-treatments (physico-chemical, thermal, mechanical, etc.) using few or no chemical reagents. The pre-treatments envisaged must (and will have to) be environmentally friendly.
The deconstruction of agro-resources can also have different aspects with the study of the biodegradability of new assemblies but also the valorization of molecules obtained by biological degradation processes.

Develop recyclable and/or compostable barrier packaging to replace current multilayer films that are incinerated (44%) or landfilled (56%).
This project is financed by the European Union and the Normandy Region.
The multilayer film market represents 50% of the global market for flexible packaging, which alone generates 10MT of waste per year in Europe, or 36% of plastic waste.
Fossil-based multilayer solutions meet the requirements imposed by packaging applications, but their complex structure (assembly of different polymer layers) makes them non-recyclable, while bio-sourced solutions do not today offer all the properties such as barrier, mechanical characteristics, transparency, bacterial safety and sealability.
The main challenge of the project is to lift these locks while keeping recyclability and/or compostability in the spirit of the circular economy. From an economic point of view, REACT aims to set up in the Normandy region of France, a sector allowing the design, production and recovery of recyclable and/or compostable barrier plastic packaging.

Ozone, whose effectiveness has been demonstrated in various industrial applications, is still little used in the agro-industrial sector. However, the increasing health requirements impose a continuous improvement of food preparation methods. The FUI Ozone 2020 project is part of this dynamic, anticipating and responding to the key challenges of food quality/safety. Based on a partnership model uniting different academic/industrial specialists (Actalia, Bonduelle, Etia, Suez Environnement, UniLaSalle), the Ozone 2020 project aims to develop and deploy two applications to reduce the biological contamination of plant-based products. This project initially targets divided dry products and ready-to-use raw plants.

The project VALOEQUIBOUE - VALOrisation of EQUIns manure and MUD from mixed waste water treatment plants by methanisation, is led by UniLasalle, the Université de Technologie de Compiègne and the SIAAP-DDP and is part of the MOCOPEE programme MOdélisation, Contrôle et Optimisation des Procédés d'Epuration des Eaux, 2nd phase (2018-2022).
The anaerobic digestion of equine manure coupled with the anaerobic digestion of WWTP sludge is a major issue to valorize these resources. This anaerobic digestion of equine manure and WWTP sludge in mixture, called co-digestion, has a strong biogas production potential and a high added value at the energy, agronomic and economic level. The project is divided into several tasks carried out within the framework of Arnaud COUTU's PhD: i) pre-treatment of horse manure by ozonation and other innovative technologies to improve anaerobic digestion; ii) biodegradation by wet anaerobic digestion of horse manure; iii) definition of operating parameters (hydraulic residence time, temperature, agitation, applied load, single or sequenced reactor, ...); iv) co-digestion with sewage treatment plant sludge and possibly other resources.

Study of the effect of a vitamin D enrichment process by an innovative treatment on the quality of an ingredient. This research program aims to obtain a new ingredient enriched in vitamin D by confidential UV treatment. The objective is to characterize the impact of this treatment on commonly consumed food raw materials and to allow, subsequently, a marketing authorization. We are working on new raw materials, for which the process has yet to be proven in order to enrich them with vitamin D and limit the formation of undesirable neoformed compounds.
