Jan 1, 2010 · In 1833 Anselme Payen (1795-1871) and Jean-François Persoz (1805-1868) (Payen and Persoz, 1833) found that the transformation of starch discovered by Kirchhoff was attributable to the action of a special substance, which they called diastase (amylase). Payen and Persoz found that the activity of diastase is eliminated by heating to 100°C.

Image by Alex Hopes (Direct Permission granted from Artist, 2021) In 1815, the French chemist Anselme Payen 1, then just twenty years old, was entrusted to manage a borax refining facility. Five years later, he began to refine sugar from beets.
Anselme Payen. 1795-1871. French chemist who made advances in the study of carbohydrates and enzymes. Payen developed a charcoal filter used to decolor sugar. He discovered diastase, an organic catalyst that converts starch to the sugar maltose and the first enzyme produced in concentrated form.
Payen was in the main supported by Schulze, although other inves tigators, among them Erdmann, opposed Payen's views. It is of in terest, however, to point out that Payen's "incrustation hypothesis" has in more recent years been vigorously supported by Wislicenus and by Freudenberg. Anselme Payen was born in Paris, France, on January 6, 1795. He
