Australian margarine for a very long time was based by law on tallow but as a result, the Australian industry learnt a great deal about the physical properties of animal fat and the modification of the flavour and texture of that raw material. So much so that the knowledge gained in at least one company was applied in Europe also. For a time in the 1940s catalysts for oil modification were made in Australia but this was a temporary measure and has long been discontinued. Unit processes used in the industry were derived from overseas but there had been some Australian modification and development of them and the manufacture of some novel products.
In the 1950s, a considerable amount of hydrogenated whale oil was used but the development of the polyunsaturated fats health story boosted vegetable oil production, usage, and quality in the early 1960s and provided better raw materials for margarine and other food products, such as salad dressings, as well as a wider range of edible oil products manufactured to tight specifications for particular food product usage. This has been assisted by the development of very accurate and rapid analytical methods and their application via computer link to factory control. In this the Unilever R & D laboratory in Sydney has played a significant part.[88]
