- Title
An industry consensus study on an HPLC fluorescence method for the determination of (n)-catechin and (n)-epicatechin in cocoa and chocolate products.
- Abstract
The article presents information on the results of an HPLC study which determines the flavan-3-ol monomers, (+)-catechin and (+)-epicatechin, in cocoa and plain dark and milk chocolate products. The study analysed a series of samples by laboratories of five member companies using a common method. The percent coefficient of variation (%CV) of the sample set ranged from approximately 7 to 15 percent. It is concluded that the proposed method is well suited as an HPLC method for the determination of flavanol monomers in chocolate and cocoa.
