(a) 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 with the methods A and B after treatment at 25°C and 40°C. The columns with different letters are significantly different according to the Tukey test ( < 0.05). (b) Schematic representation of the effect of the temperature and pH on the particles.
