The quantify of bioaccessibility aims to quantify the fraction of a compound released from the food matrix and is potentially available for absorption and metabolism. To reach the intestinal portion and become bioaccessible and, consequently, bioavailable, bioactive ingredients, such as phenolic compounds, need to overcome the barriers of the gastrointestinal tract, which include the variation in the pH of digestive fluids and the action of digestive enzymes. In this chapter, we describe the procedures for determining the bioaccessibility of phenolic compounds from coffee husks.

摘要

The quantify of bioaccessibility aims to quantify the fraction of a compound released from the food matrix and is potentially available for absorption and metabolism. To reach the intestinal portion and become bioaccessible and, consequently, bioavailable, bioactive ingredients, such as phenolic compounds, need to overcome the barriers of the gastrointestinal tract, which include the variation in the pH of digestive fluids and the action of digestive enzymes. In this chapter, we describe the procedures for determining the bioaccessibility of phenolic compounds from coffee husks.
