A sensitive and selective method for the quantitative determination of fatty acid tryptamides as shell indicators in cocoa products
1999
Munch, M. | Schieberle, P.
Tetracosanoyl-2-(3-indolyl)ethane amide (lignocerinic acid tryptamide; LAT) and docosanoyl-2-(3-indolyl)ethane amide (behenic acid tryptamide; BAT) were indified at the most prominent tryptamides in cocoa shells based on electrospray ionisation mass spectrometry and H NMR measurements. The results have shown that cocoa shells contain LAT and BAT in a constant ratio of nearly 2:1. Although minor amounts of the tryptamides are also present in the cocoa cotyledons, BAT and LAT can be proposed as indicator substances to measure the shell content in cocoa products.
