In vitro digested olive pomace as a source of bioactive compounds

Olive pomace (OP) represents a by-products of olive oil industry produced in large volume annually. Connected to OP production, there are problems of environmental pollution and operating costs to neutralize it. However, OP represents also a natural source of various nutrients and bioactives such as phenolic compounds, unsaturated fatty acids, antioxidant dietary fiber and minerals. The aim of this study was to assess how an in vitro simulation of gastrointestinal digestion of OP, followed by dialyses process to simulate the intestinal and blood absorption, influence its phenolic composition and bioactivities.
