Resumo

This work aimed to study the formation of lycopene-loaded hydrolysed collagen (LLHC) particles by supercritical CO2 impregnation. For this, a mixture of 9.09 g of hydrolysed collagen powder and 0.91 g of lycopene was placed in an autoclave for contact with supercritical CO2 at pressures of 150 and 250 bar, and temperatures of 50 and 60 degrees C, with agitation at 1250 rpm for 45 min. At 60 degrees C (150 and 250 bar), the mixture became a viscoelastic mass. At 50 degrees C (150 and 250 bar), lycopene was loaded into the physical structure of the hydrolysed collagen powder particles. LLHC particles formed at 150 bar and 50 degrees C, when compared to 250 bar and 50 degrees C, showed fissures on their surface, which enabled possible electrostatic interactions and better impregnation and distribution of lycopene. Thus, supercritical CO2 impregnation at 150 bar and 50 degrees C is recommended for the formation of LLHC particles. (AU)
