| Summary: | Lycopene is a carotenoid with known benefits on human health and of wide use in pharmaceutical and food industry. The objective of this research was to evaluate the extraction of lycopene in guava pulp assisted by the enzyme pectinase. Parameters such as enzyme concentration and incubation time were evaluated. The results indicated that the enzyme improved the extraction of lycopene from guava pulp. An increase in lycopene yield of 38.65% was obtained, with a pectinase concentration of 0.02% (v/w of substrate) after 45 min of incubation, at 28°C and pH of 4.5. Under these conditions, the concentration of lycopen extracted was 40,08 ug/g fresh material. Pectinase treatment increases the bioavailability of lycopene in guava pulp, offering an interesting alternative in extraction processes of such important antioxidant.
