This document aims to harmonise the most employed methodologies to determine Total Polyphenolic Content (TPC) and Antioxidant Activity (AA) in extracts from agri-food by-products.
Although these methodologies are derived within the framework of the NeoGiANT H2020 project, using white grape marc extracts, they can be extrapolated to extracts from agri-food industry, such as fruit or vegetable by-products.
