Responsible's address: suming.li@umontpellier.fr
End Date:28/02/2025
Task Leader: UMF.
contribution of: UGT, UMV-R, MU and ITA .
To study the functionalities of biopolymers (proteins and carbohydrates) extracted from OS with the final aim to define strategies for their exploitation.
- Extraction of biopolymers (proteins and polysaccharides)
Extraction of biopolymers (proteins and polysaccharides) using conventional and innovative technologies for selective extractions (solvent, enzyme, microwave and ultrasound-assisted extractions, preparative chromatography, ultrafiltration, etc.).
- start date: 01/03/2024
- end date: 31/08/2024
- Task’s leader: Dr. Hana Maalej
- Characterization of extracted biopolymers
Characterization of extracted biopolymers by using nuclear magnetic resonance (NMR), high performance liquid chromatography (HPLC), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), gel permeation chromatography (GPC), scanning electron microscopy (SEM), thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) to determine the composition, crystalline structure, molar mass, morphology and thermal properties.
