Abstract

Grumixama (Eugenia brasiliensis), cereja-do-Rio-Grande (Eugenia involucrata) and ara & ccedil;a & uacute;na (Psidium myrtoides) are purple-red Brazilian native fruits rich in antioxidants. In this study, different fruit aqueous extractions were made at 22 degrees C/120 min and 90 degrees C/7 min, and colour, pH, total phenolic content (TPC), anthocyanin content (MAC) and profile (HPLC-DAD), and antioxidant capacity (ORAC and ABTS) were evaluated. The hot extraction protocol was more efficient in recovering phenolic and anthocyanin compounds. The ara & ccedil;a & uacute;na infusion presented the highest TPC (32.61 mg GAE/100 mL) and ABTS (188.70 mu mol TE/100 mL), and those from grumixama the highest MAC (11.17 mg C3G/100 mL) and cereja-do-Rio-Grande the highest ORAC (332.70 mu mol TE/100 mL). Cyanidin-3-glucoside and delphinidin-3-glucoside were the major anthocyanins in all infusions. After 48 h/4 degrees C of storage, TPC and anthocyanins loss achieved 7.4% and 40.8%, respectively, evidencing the high degradative anthocyanins' susceptibility over time. Purple-red fruit infusions, mainly hot infusions, are potential functional foods. (AU)
