Juice by-products as a source of dietary fibre and antioxidants and their effect on hepatic steatosis

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 presen...

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 β-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 α-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 (~25%). Hepatic steatosis was reduced by all by-products. Juice by-products improved some complications of obesity.http://www.sciencedirect.com/science/article/pii/S1756464615002340Dietary fibreJuice by-productsAntioxidantsObesity
