Milk pasteurization has been around since the 1800s. Thanks for this go to Louis Pasteur, who demonstrated in the 1860s that abnormal fermentation of wine and beer could be prevented by heating the beverages, and to Frans von Soxhlet, a German agricultural chemist, who in 1886, was the first person to suggest that milk sold to the public be pasteurized. The benefits of heating or boiling milk have been recognized since the early 1800s and has been used to reduce milk-borne illness and mortality

The benefits of heating or boiling milk have been recognized since the early 1800s and has been used to reduce milk-borne illness and mortality in infants since the late 1800s. Foodborne illnesses such as typhoid, scarlet fever and tuberculosis were virtually eliminated with the commercial implementation of pasteurization. | Food Science Babe
