eng	Electrochemical determination of cocoa content in chocolates	The objective of this research was to develop an instrumentally simple analytical tool for determination of cocoa solid content in chocolates which should be based on amperometric oxidation of all present antioxidants in chocolates at boron-doped diamond electrode (BDDE) that is integrated in a flow injection analysis (FIA) wall-jet electrode system. Obtained high positive correlation between the determined values of Trolox equivalent antioxidant capacity (TEAC) and cocoa mass fractions characterised by correlation coefficient of 0.9187 for eight randomly selected samples (one white, two milk, and five dark chocolates) confirmed that cocoa solids represent the main source of antioxidants. Consequently, TEAC values could be considered as an additional marker of cocoa content in the chocolate analysis to the commonly used theobromine (authenticity of food prod	Amperometry; trolox equivalent antioxidant capacity; boron-doped diamond electrode; flow injection analysis; cocoa mass fraction in chocolate
