Thermal and acidic stabilization of amino acids using dextran-based formulations

Overview

A dextran-based formulation platform that stabilizes amino acids against thermal degradation and acidic environments while enabling controlled, pH-dependent release. The technology uses dextran, a biocompatible polysaccharide, as a protective matrix that entraps amino acids and limits their molecular mobility, shielding them from degrading conditions. This approach addresses key challenges in amino acid stability for pharmaceutical, nutraceutical, cosmetic, and food applications where exposure to heat or low pH can compromise product quality and shelf life.

Technical specifications

Key features:

• Thermal protection: Dextran matrix restricts molecular mobility and diffusion of amino acids, reducing temperature-induced degradation
• Acidic shielding: Protective barrier minimizes exposure of amino acids to harsh acidic conditions
• Controlled release: pH-dependent release behavior supports sustained bioavailability over time
• Stable complex formation: Physical and chemical entrapment methods create robust dextran-amino acid complexes
• Characterization-ready: Compatible with standard analytical techniques including FTIR, NMR, HPLC, UV-Vis spectroscopy, particle size analysis, and zeta potential measurement
• Biocompatibility: Built on dextran, a well-established biocompatible and safe polysaccharide

Technology readiness level

This research is at an early-stage development phase (TRL 2-3). The hypothesis is supported by established knowledge of dextran's matrix-forming properties, but experimental validation is still in progress. Planned validation includes formulation design, thermal and acidic stability testing, encapsulation efficiency and loading capacity determination, FTIR interaction studies, and bioactivity assays. The technology is positioned for collaborative research partnerships to advance proof-of-concept studies and characterize formulation performance under varied conditions.
