Who introduced processed cheese in 1915?

While cheesemaking had been around for centuries, Kraft's innovation was the process of emulsifying cheese using sodium phosphate and other emulsifiers, creating a smooth, spreadable product that was less likely to spoil. This process revolutionized the cheese industry and made cheese more accessible to consumers.

While Kraft wasn't the first to process cheese (a similar process was used in Switzerland in the 19th century), his invention was crucial in popularizing and commercially producing processed cheese.
