Synthesis and Characterization of Chitosan Particles Loaded with Antioxidants Extracted from Chia (Salvia hispanica L.) Seeds

Figure 6

DPPH radical scavenging activity of precursors (CH and TPP), blank particles (0.0 mg·mL⁻¹), and chia extract-loaded particles with different concentrations synthesized by methods A and B after treatment with acidic and basic solutions. The columns with different letters are significantly different according to the Tukey test ( < 0.05).
