Theobromine and caffeine content of chocolate products
Commercial chocolate products were analysed for theobromine and caffeine content by High Performance Liquid Chromatography. Levels in 22 samples of chocolate liquior averaged 1.22 percent theobromine and 0.21 percent caffeine. Commercial cocoas contained, on the average, 1.89 percent theobromine and 0.21 percent caffeine. Sweet chocolate averaged 0.46 percent theobromine and 0.07 percent caffeine, while milk chocolate averaged 0.15 percent theobromine and 0.02 percent caffeine. Hot cocoa (chocolate) beverages averaged 65 mg of theobromine and 4 mg of caffeine per 5 ounce serving and chocolate milk prepared from a variety of cocoa-sugar mixes averaged 58 mg of theobromine and 5 mg of caffeine per 8 ounce serving. Theobromine and caffeine levels varied widely in individual samples within the product categories examined. Also, the ratio of theobromine to caffeine varied widely among different chocolate liquors ranging from a low of 2.5:1 to a high of 23.0:1.
