Preparation of β-cyclodextrin/polysaccharide foams using saponin

Area of Science:

• Biomaterials Science
• Polymer Chemistry
• Green Chemistry

Background:

• Cyclodextrins are cyclic oligosaccharides forming inclusion complexes with hydrophobic molecules.
• Polysaccharides like xanthan gum, locust bean gum, and chitosan can be functionalized and crosslinked.
• Citric acid and β-cyclodextrin facilitate the crosslinking of polysaccharides into insoluble matrices.

Purpose of the Study:

• To prepare novel polymeric foams using polysaccharides and saponin via a green synthesis method.
• To enhance the porosity of polysaccharide-based matrices.
• To evaluate the impact of synthesis procedures on foam porosity and sorption properties.

Main Methods:

• Preparation of polymeric foams using xanthan gum, locust bean gum, or chitosan.
• Utilizing citric acid and β-cyclodextrin for polysaccharide crosslinking.
• Incorporation of Quillaja saponaria saponin to create porous structures.
• Investigating different synthesis pathways for foam fabrication.
• Assessing the porosity and aqueous phase sorption capacity of the resulting materials.

Main Results:

• Successful preparation of polymeric foams from polysaccharides and saponin using a green method.
• Demonstrated ability to increase matrix porosity through foam formation.
• Variations in synthesis procedures led to differences in material porosity.
• The developed foams exhibited notable sorption capacities in the aqueous phase.

Conclusions:

• Green synthesis offers a viable route to produce porous polysaccharide-saponin foams.
• The choice of synthesis path significantly influences the porosity and sorption characteristics of the foams.
• These novel materials show promise for applications requiring controlled porosity and sorption.
