This study was designed to assess the effect of honey addition to
the antioxidant capacity and in vitro bioaccessibility of phenolic
content of both brewed and soluble coffee. Floral and pine
honey were used in the assay. The antioxidant capacities of the
samples were evaluated with three different methods: DPPH
radical scavenging activity, cupric reducing capacity and total
antioxidant capacity tests. In order to measure the antioxidant
metabolites of the samples, total phenolic and flavonoid contents
were appraised. In vitro gastrointestinal digestion simulation
procedure was conducted to mimic the physiochemical and biochemical factors of the gastrointestinal tract. During the
digestion process, components in the food matrix are exposed
to significant structural changes and certain amount of them are
effectively absorbed and reach the circulation. To that end, the
importance of studies concerning the simulated gastrointestinal
digestion increases. The results of this study revealed that honey
addition to coffee samples induced increases in antioxidant
capacities, total phenolic and flavonoid contents.
