Research topic

Cellulose nanoparticles (nanocrystals and nanofibrils) in food systems: novel food packaging materials; bioactive functionalized components; releasing systems; bioprocesses for by-products valorization; biorefinery high value added products


Project Synopsis

This PhD research will consist of implementing novel packages (fully compostable) based on the use of the Cellulose Nanoparticles (CNs) isolated from the cellulose, which is abundantly available in waste materials (wood pulp, cotton linter …) and by-products (rice and soy husks…). Owing to the biodegradability and unique gas barrier& mechanical properties of the CNs, those bio-based packages might be used for food shelf-life extension shaping the food quality& safety with concomitant environmental and economic expectations in a real circular economy in food packaging. However, to make that project possible and effective, two main drawbacks have to be sorted out. Firstly, the high tendency of the Cellulose Nanoparticles to swell in presence of humidity is detrimental to the gas barrier properties and secondly, the CNs are not heat sealable to form multi-layers’ packages. A couple of solutions retained plausible have been investigating such as an attempt to modify the CNs surface into more hydrophobic structure for increasing the nanocrystals functionalities to be coated onto either external film side or between two plastic films and promoting their potential mixing with adhesives.
