His work on the sterilization of milk for infants led him in 1886 to propose pasteurization to be applied to milk and other beverages.

Soxhlet extractor was originally designed for the extraction of a lipid from a solid material. However, a Soxhlet extractor is not limited to the extraction of lipids. The Soxhlet extraction has widely been used for extracting valuable bioactive compounds from various natural sources. It is used as a model for the comparison of new extraction alternatives.
