Carvacrol content in the obtained composite was determined by thermic desorption Gas Chromatography, using a HP 7890B equipped with a HP5 column of 30 m, 320 µm of diameter and 0.25 µm of thickness. The thermic gradient employed was: 40 ºC (3 min), 10 ºC•min -1 ramp until 200 ºC and 15 min isotherm. Injector heats on ballistic ramp (600 ºC•min -1 ) from 40 to 200 ºC and 4 min isotherm. Equations used for calculations of loading capacity and encapsulation efficiency are further described in the supporting material.
