Popis: Infusions of green tea (GT) and black tea (BT) and the use of Saccharomyces cerevisiae as a natural matrix were employed to check the impact of biosorption on the possible fate of tea polyphenols in the gastrointestinal tract in terms of bioaccessibility and total antioxidant capacity (TEAC and ORAC assays). The maximum biosorption yields obtained were 47.61 ± 11.57 and 99.68 ± 5.25 mg/g from GT and BT infusions, respectively. A significant increase (p
