  1. Caffeine Transport in Single CupCoffee Packets Eric Anderson Alana Warner-Tuhy

  2. Introduction • Reason for Study • Experimental Parameters • Results • Conclusions • References

  3. Justification for Study • Warning on the back of coffee packet • How much does brewing conditions affect the final caffeine concentration?

  4. Experimental Parameters • Three different brewing methods • No interference • Dunk bag in water, as per directions • Continuously stir • Other than convective conditions, all other parameters were constant

  5. Purification and Extraction

  6. Method 1 Results

  7. Color Comparison

  8. Caffeine Conc. Comparison

  9. Final Caffeine Comparison

  10. Results 5 Minutes • Any method will work 10 Minutes • Double the caffeine by leaving coffee undisturbed • 4 times the caffeine by continuously stirring coffee

  11. Conclusions • The convective component greatly affects the final caffeine concentration • Color is not an adequate indicator of caffeine concentration

  12. References • Spiro, M., Lam, P., Food Chemistry, 1995 , vol. 54, p393-396.
