Peach palm (Bactris gasipaes) is an orange, red or yellow fruit widely cultivated inCentral America. It is an energy-rich source of carbohydrates, fats and carotenes, and containssmall amounts of protein and fiber. The aim of this study was to describe its carotenoidconcentration, antioxidant activity and glycemic index. For the carotenoid composition,antioxidant activity and lipid peroxidation protection two B. gasipaes varieties were analyzed:Ecuador and Yurimaguas. Total carotenoids content was 7.43±0.2 mg/100g for Ecuador and5.74±0.05 mg/100g for Yurimaguas. The amount of each variety necessary to reach 50% radicalscavenging activity (DPPH) was 11.6±0.2mg carotenoids/mL for Yurimaguas and 9.1±0.3mgcarotenoids/mL for Ecuador. In addition, the IC50 of the inhibition lipid peroxidation was11.2±2.1?g carotenoids/ml and 10.9±2.2?g carotenoids/ml for Yurimaguas and Ecuadorrespectively. Glycemic index value obtained was 35±6, which classified B. gasipaes as a low GIfood. It is concluded that peach palm is an important source of carotenoids and its antioxidantactivity and low glycemic index can provide nutritional benefits that may play an important role inthe prevention or management of several chronic diseases.
