Abstract:
The global increase of morbidity from chronic noncommunicable diseases attributable to diet has made consumers pay more attention to what they eat, with the intent to consume more fruits and vegetables with high phytochemical compound contents of high functional value. Asaí and copoazú are two Amazonian fruits that are considered “superfruits”, with a high content of phytochemicals with an antioxidant capacity, that, when combined in juices, provide a pleasant flavor. Microencapsulation is a suitable technique for the preservation of compounds of interest in powdered products. The objective of the present study was to evaluate the functional potential of an asaí and copoazú microencapsulation (MAC) supplied to healthy volunteers. Healthy volunteers were evaluated nutritionally with a food consumption survey and a 24-h reminder to establish their average diet and avoid interference with the supplied microencapsulation. Anthropometric measurements, weight and height, were taken. The biochemical parameters evaluated in each subject were: cholesterol, triglycerides, high density cholesterol (HDL-C), low density cholesterol (LDL-C), very low cholesterol (VDL-C), uric acid, creatinine, blood glucose, fasting insulin, insulinic sensitivity, estimated using the Homeostasis Model, HOMA-IR, and indicator of oxidative stress: 8-Isoprostane and nitric oxide like endothelial marker dysfunction The evaluations were performed at baseline (before receiving the drink) and at endpoint (31 days). The results did not show significant variations (P=0.05) in the anthropometric measurements. The LDL-C and NO showed significant differences from the beginning and the end of the assay. The 8-iso-PGF2α show positive correlations with NO at the endpoint of the study. The consumption of MAC by the healthy volunteers proved to be a promising functional drink for combating oxidative stress.
