UMR Procédés Alimentaires et Microbiologiques

Axe 3 - Encapsulation and activity

Topic 3: Structuring of matrices and vectorization

Supervisors: Prof. Odile Chambin and Prof. Yves Waché

Study the structure of functional matrices by improving understanding of interactions between:

- Biopolymer matrices and active molecules
- Cellular entities and active molecules (encapsulating cells)

- Biopolymer matrices and cell entities (encapsulated cells)

Benefits of cross-disciplinary projects to control:

  • Physico-chemical processes

  • Encapsulation

    • of active molecules or cellular entities

    • in a biopolymer matrix or in cellular entities

  • Characterisation to improve understanding (RMB and Dimacell facilities)

  • Control the release and the retention of active molecules or cellular entities

PARI Alim+: Control the activity and functionality of macromolecules and microorganisms to improve nutrition

Research question: "How can the dynamics of food macromolecules and their reactivity help to control the physico-chemical and even organoleptic properties and the functionality of food matrices (especially retention or release of active entities)?"

Encapsulation to protect fragile active molecules and to control their release/retention
Encapsulation of probiotics
Examples of work in progress:

- Development of fluorescence imaging protocols for the characterization of cells encapsulated in matrices
- Encapsulation of curcumin in pectin matrices: a means of regulating the release properties and functionalities (PhD of Duc Hung NGYUEN - 2017-2021)

Encapsulation network in South East Asia
Due to high demand for technology and years of collaboration with Thailand and Vietnam, scientists from the PAM centre spearheaded the network "Encapsulation in South East Asia".
