Description générale

Citric acid is a buffer component for triple-column amino acid analysis.[1] It is an optimal buffer for dissociation of radioiodinated antibodies from viable murine tumor cells.[2]

Application


  • Enhancing soil microbiomes: Citric acid has been applied to modify soil bacterial communities in saline mudflats, demonstrating its utility in environmental biotechnology for sustainable ecosystem management (Liu et al., 2024).

  • Biodegradable packaging in food industry: In food chemistry, citric acid is used in conjunction with polyvinyl alcohol for developing antimicrobial packaging, highlighting its potential in food safety and preservation (Xu et al., 2024).

  • Nanomaterial synthesis for engineering applications: Citric acid serves as a key component in the eco-friendly synthesis of hybrid nanomaterials for supercapacitors, underpinning its role in advancing materials science and engineering (Teixeira et al., 2024).

  • Environmental science and pollution control: Research utilizes citric acid to study the co-transport of pharmaceuticals and nanoparticles in environmental systems, aiding in the understanding of contaminant dynamics and mitigation strategies (Cui et al., 2024).

  • Food science and technology: Citric acid is employed in the formulation of vegan gummies, indicating its versatility in food product development and its impact on textural properties (Rawat et al., 2024).
