Zero-solvent-emission rapid synthesis of aerogel beads: A food-colorant adsorbent with biocompatibility and facile separation

Key Points

• Aerogel beads showed strong adsorption capabilities for food colorants, significantly enhancing purification processes.
• The study revealed a 98% adsorption efficiency within 30 minutes for the tested food colorants, indicating rapid effectiveness.
• Synthesis of aerogel beads was achieved without solvent emissions, promoting eco-friendly production practices.
• These findings suggest that the developed aerogel could be a viable option for food safety, although further testing on scalability is needed.
