“A high performance liquid chromatography (HPLC) method for the separation of triglycerides in cocoa butters at nanogram sensitivity is described. This procedure is based on UV detection at 220 nm.”

HPLC → used for → separation of triglycerides in cocoa butters

“To further narrow down the number of key taste compounds, finally, taste omission experiments and human dose/response functions were performed, demonstrating that the bitter-tasting alkaloids theobromine and caffeine, seven bitter-tasting diketopiperazines, seven bitter- and astringent-tasting flavan-3-ols, six puckering astringent N-phenylpropenoyl-l-amino acids, four velvety astringent flavonol glycosides, gamm”

bitter-tasting alkaloids theobromine and caffeine, bitter-tasting diketopiperazines, bitter- and astringent-tasting flavan-3-ols, puckering astringent N-phenylpropenoyl-l-amino acids, velvety astringent flavonol glycosides → contribute to → taste profile of roasted cocoa nibs

“However, the extent to which the inherent bean constituents from the cocoa genotype, environmental factors, post-harvest treatment, and processing technologies influence chocolate flavor formation and relationships with final flavor quality, has not been clear.”

inherent bean constituents from the cocoa genotype, environmental factors, post-harvest treatment, and processing technologies → influence → chocolate flavor formation and relationships with final flavor quality

“followed by 3-methylbutanal (cocoa-like)”

3-methylbutanal → contributes to → cocoa-like aroma

“At the acute time point, consumption of cocoa significantly improved self-reported mental fatigue and performance on the Serial Sevens task in cycle one of the CDB.”

cocoa flavanols → improved → self-reported mental fatigue and performance on the Serial Sevens task
