•Stability of lycopene nanocapsules at photosensitization, heating and freezing.•Technique of interfacial deposition of preformed polymer.•Nanoencapsulation increased the stability of lycopene.
The objective of this study was to evaluate the stability of nanoencapsulated lycopene (LYC-LNC) prepared by interfacial deposition of preformed poly(ε-caprolactone) (PCL) during photosensitization (5 °C–25 °C), heating (60 °C–80 °C) and refrigeration (5 °C). LYC-LNC presented a concentration of 80.71 μg/mL and was also analyzed in terms of mean diameter, zeta potential and morphology, as well as the position of the lycopene in the particle. During photosensitization and heating in air-saturated conditions, LYC-LNC showed activation energy of 67 kcal/mol and 24.9 kcal/mol, respectively. Those values were superior to that of free lycopene as found in the literature for both experiments. During refrigeration at 5 °C, the mean diameter and zeta potential of LYC-LNC remained stable for 84 days and presented approximately 40% of lycopene content. All experiments suggest that nanoencapsulation improves the stability of lycopene under different processing conditions.
