In which year did Andreas Sigismund Marggraf discover that sucrose is responsible for the sweetness of sugar beets and sugar cane?

Andreas Sigismund Marggraf's discovery in 1774 identified sucrose as the compound responsible for the sweetness found in both sugar beets and sugar cane. This was a significant breakthrough in the understanding of carbohydrates, particularly in the context of sugar production. Marggraf’s work laid the foundation for future developments in sugar chemistry and the agricultural practices surrounding sugar crops. His discoveries contributed to the broader understanding of plant biochemistry and eventually influenced the sugar industry, enhancing production methods and driving scientific inquiry into other types of sugars and their properties. The timeline places this discovery in the late 18th century, which coincides with significant advances in chemistry and a growing interest in understanding the constituents of food.
