Abstract
This chapter focuses on the recovery of bioactive compounds, particularly phenolic compounds and dietary fiber, from fruit juice industry solid waste. Extraction, isolation and potential applications of phenolic compounds and dietary fiber recovered from fruit solid waste in the food industry will be discussed. With the continuity of new discoveries on extractions, isolation and characterization techniques, the use of such waste as cheap raw material to produce bioactive compounds on a commercial scale becomes tangible on a large scale. Without any extraction step prior to the fiber preparation, dietary fibers obtained directly from fruit waste contain high amounts of bioactive compounds, such as phenolic compounds, terpenes, carotenoids, depending on the fruit sources. In many reports on the use of bioactive compounds from fruit waste in food products, antioxidant activity is reported to have a synergistic effect with the addition of dietary fiber.
