Meat extract was invented by Baron Justus von Liebig, a German 19th-century organic chemist. Liebig specialised in chemistry and the classification of food and wrote a paper on how boiling meat destroys its nutritional value. Liebig's view was that meat juices, as well as the fibres, contained much important nutritional value and that these were lost by boiling or cooking in unenclosed vessels. Fuelled by a desire to help feed the undernourished, in 1840 he developed a concentrated beef extract, Extractum carnis Liebig, to provide a nutritious meat substitute for those unable to afford the real thing. However, it took 30 kg of meat to produce 1 kg of extract, making the extract too expensive.

Liebig's Extract of Meat Company
Liebig went on to co-found the Liebig's Extract of Meat Company, (later Oxo), in London whose factory, opened in 1865 in Fray Bentos port Uruguay, took advantage of meat from cattle being raised for their hides—at one third the price of British meat. Before that, it was the Giebert et Compagnie (April 1863).
In the 1870s, John Lawson Johnston invented 'Johnston's Fluid Beef', later renamed Bovril. Unlike Liebig's meat extract, Bovril also contained flavourings. It was manufactured in Argentina and Uruguay which could provide cheap cattle.
Liebig and Bovril were important contributors to the beef industry in South America.
Meat extracts have largely been supplanted by bouillon cubes and yeast extract. Some brands of meat extract, such as Oxo and Bovril, now contain yeast extract as well as meat extract. For example, the current formulation of Bovril contains 41% beef stock, 24% yeast extract, 1% dehydrated beef and salt (3.88g sodium per 100g), spice extracts and flavour enhancers among other ingredients. High purity meat extract is still available from laboratory supply companies for microbiology.
