1899 – Milk Homogenizer Is Patented

“In 1899 Auguste Gaulin obtained a patent on his homogenizer. The patent consisted of a 3 piston pump in which product was forced through one or more hair like tubes under pressure.”

Homogenization breaks down the large fat globules in milk into tiny ones.

The process prevents the cream from separating and rising to the top as it does in un-homogenized milk.
