In vitro digestion of zingiber officinale extract and evaluation of stability as a first step to determine its bioaccesibility

Zingiber officinale (Ginger) is one of the most spice used worldwide and since antiquity it has been used in traditional medicine to treat different diseases. Although ginger is generally considered safe, there are no more information about the mechanism of its therapeutic action and its nutraceutical value. For these reasons the purpose of this work is to apply in vitro digestion model, as the first step in the study of its bioaccessibility, to understand which is the fate of its bioactive compounds after ingestion. This allow us to characterize which ginger metabolite are stable under gastrointestinal conditions and, thus, available for intestinal absorption. The aim of this study is to provide valuable information to better understand ginger pharmacological activities, paving the way for the definition of suitable dosage and source of food matrices to ensure nutritional efficacy.
