Evaluation of bioactive compounds, chemical and technological properties of fruits byproducts powder

Millions of tons of fruit byproducts are discarded globally every day by food processing industries, which represents a considerable loss in terms of nutrients. The goal of this work was to evaluate the physico-chemical, technological, antioxidant properties and characterization of carotenoids for papaya, pineapple, olive byproducts and anthocyanins for blueberry byproducts. The results indicated that these byproducts are good sources of total dietary fiber, especially olive byproducts (53.68%). The powder from papaya byproducts showed the highest values for the technological characteristics of water holding capacity (8.93 g water/g powder) and solubility (59.91%). All of the powders exhibited a good ability to reduce Folin Ciocalteu reagent and a high DPPH radical scavenging capacity, especially the powder from blueberry byproducts, which also exhibited a high level of anthocyanins (2063.4 mg/100 g). The carotenoid content was highest in the papaya powder sample, followed by the pineapple and olive powders. The results of this study indicate the high potential application of these powder byproducts as functional ingredients in food products because they can be considered a good source of antioxidant compounds.
