摘要：

Alternative sources of antioxidant dietary fibre, such as juice by-products, can be used in the prevention of obesity and its complications. In this study, the nutraceutical compounds of mango, guava and peach by-products from the juice industry were characterized. Mango and peach by-products presented an adequate balance of insoluble/soluble dietary fibre, as well as a high content of carotenoids (27.9 and 2.4 mg beta-carotene/g, respectively) and polyphenols (102.0 and 83.6 GAE mg/g, respectively). Guava by-product presented the highest content of insoluble dietary fibre (74%). Several phytosterols and saponins were identified in all by-products. Juice by-products decreased the activity of a-amylase, and scavenged DPPH and nitric oxide radicals. An in vivo study was carried out in high fat and fructose (HF/HFr) diet-fed rats. Guava by-product decreased bodyweight gain (8%) and peach and mango by-products reduced hyperglycaemia (similar to 25%). Hepatic steatosis was reduced by all by-products. Juice by-products improved some complications of obesity. (C) 2015 Elsevier Ltd. All rights reserved.
