Açai Fruit Clinical Studies

Study #1


"The antioxidant capacities of commercial and non-commercial pulps and seeds of the Euterpe oleracea Mart., Arecaceae, (Açaí) palm were surveyed against peroxyl radicals, peroxynitrite and hydroxyl radicals. Analysis were carried out with the Total Oxidant Scavenging Capacity (TOSC) assay in a modified and automated version. The results were compared to several standard compounds as well as to a number of common European fruit and vegetable juices. Several antioxidants present in Açaí pulps and seeds were identified, quantified and their contribution to the overall antioxidant capacities..."

Study #2


"Açaí, a member of the genus Euterpe , is indigenous to Central and South America and grows in the Amazon estuary as well as in swamps, upland regions, and floodplains. The Açaí palm is tall and slender, growing 15 to 30 m in height. The leaves are feather-like or pinnate in shape and grow up to 3 m in length. 4 The plant is multi-stemmed and produces 3 to 4 bunches of round fruits 1 to 1.5 cm in diameter, with each bunch of fruit weighing 3 to 6 kg. The fruits appear in green clusters when immature and ripen to a dark purple color. Each Açaí fruit contains a seed that accounts for nearly 90% of its weight and diameter. The seeds are covered with a fibrous layer..."

Study #3


"High intake of fruits and vegetables was found to positively associate with lower chance of many diseases by epidemiological studies and clinical trials. Antioxidant capacity was believed to be one of the possible mechanisms, though others are also involved. Açaí, fruits of Euterpe oleraceae Martius, is consumed in a variety of beverages and food preparations in the native land in Brazil, Colombia, and Suriname and used medicinally as an antidiarrheal agent (1, 2). Recently, much attention has been paid to its antioxidant capacity..."

Study #4


For the clinical trial, people were given Açaí pulp and Açaí juice containing half the concentration of anthocyanins as the pulp and each compared to the control foods: applesauce and a non-antioxidant beverage."


"Blood and urine samples at 12 and 24 hours after consumption showed significant increases in antioxidant activity in the blood after both the Açaí pulp and applesauce consumption, she said. Both Açaí pulp and Açaí juice showed significant absorption of antioxidant anthocyanins into the blood and antioxidant effects...”
