Physical Refining Deodorisation Oil Palm Knowledge Base
A Short History In the early days of the edible oil processing industry, in the first half of the 19th century, there was little or no need for refining. Food fats (e.g. lard, olive oil, milk fat, etc.) were mostly consumed unrefined and their typical flavour was
Bleaching Bleaching was introduced in edible oil refining at the end of the 19th century to improve the colour of cottonseed oil. Originally, it was a batch process at atmospheric pressure, in which natural bleaching clay was added to hot oil with the sole objective of removing colouring pigments. Today this is no longer the

Anything and Everything About Oil Palm. Chemical refining is the traditional method used in past centuries. The main purpose of chemical refining is to saponify the FFA by an alkaline solution and dilute the resulting soaps in a water phase.
Oil deodorization is the final stage in an edible oil refinery. It creates a more bland oil by removing odiferous material and other minor undesired particles, in turn increasing its shelf life. It is commonly used in the process of refining palm oil. Detailed Oil Deodorization Process

Physical refining was utilized as early as 1930 as a process for the preneutralization of products with a high initial FFA content. In this case, preneutralization was followed by caustic refining. Later, it was found possible to physically refine lauric oils and tallow if the proper pretreatment was applied before steam distillation. Physical refining became

Chemical refining is the traditional method used in past centuries. The main purpose of chemical refining is to saponify the FFA by an alkaline solution and dilute the resulting soaps in a water phase. These soaps are removed by separators. The neutral oils are subsequently bleached and deodorised. This chemical refining can be used for
Deodorization American Oil Chemists' Society
The latter effect is called ‘heat bleaching’ and it is most pronounced during deodorization/steam refining of palm oil, where the thermal breakdown of carotenes is targeted. Heat degradation of carotene is very slow at 210°C, but takes only a few minutes at T > 260°C. This is one reason why palm oil is typically deodorized at 260°C.
Edible/vegetable oil refining is a step by step process. Refining removes phospholipids, pigments, off-flavors, free fatty acids and other impurities in the crude oil. The entire vegetable oil refinery plant process comprises degumming/neutralizat...
