Function: noun
: a test for determining the fat content of milk and milk products
Babcock, Stephen Moulton (1843–1931) American agricultural chemist. During his career Babcock provided agriculture with a number of inventions and procedures, the Babcocktest being the foremost. The introduction of this test, devised in 1890, discouraged the watering down of milk, resulted in a scale for milk prices based on quality, and provided a new impetus for theimprovement of dairy herds. Babcock also invented an improved viscometer, which is used for measuring the viscosity of milk and other liquids, and did research on the nutritional value of variousfeeds, thereby providing groundwork for the discovery of vitamin A.
