QUESTION: For what discovery can Coca-Cola enthusiasts thank Mr Prof. Dr. sc. agr. Dr. rer. nat. habil. Ewald Schnug?
ANSWER: They can thank him for his two studies:
?Coca Cola Is It! The Ubiquitous Extractant for Micronutrients in Soil,? Ewald Schnug, J?rgen Fleckenstein, and Silvia Haneklaus, Communications in Soil Science and Plant Analysis, vol. 27, no. 5-8, 1996, pp. 1721- 30. The abstract reads in part:
soils, particular [sic] for manganese (Mn). The main ingredients of Coca”Coca Cola has been found to be an excellent extractant for micronutrients in Cola,
phosphoric acid, reducing sugar and carbon dioxide are well proven in common extraction recipes. The overall extraction force of Coca Cola was similar to that of commonly used phosphoric acid methods.”
