Chemical Degumming AOCS
Overview of degumming routes; Deg = degumming, Ref. = refining. Chemical degumming involves the liberation of PA from its salts with an acid that is stronger than PA itself. The degumming acid is either phosphoric acid, which forms a precipitate with Ca

Degumming an overview ScienceDirect Topics
Crude palm oil was physically refined in a 200 kg batch pilot refining plant to determine the role of drying degumming on 3-MCPD esters in the physical refining process. It was
Chemical Degumming - AOCS
The acid degumming process can be considered as an alternative to the water degumming process in that it uses a degumming acid combined with water. Crude oil, either water degummed or not, is treated by an acid, usually phosphoric acid, citric acid or malic acid in the presence of water.

Enzymatic Degumming - AOCS
R枚hm GmbH (later Lurgi) developed the first enzymatic process for degumming edible oils, the EnzyMax process, patented by Aalrust et al. [9]. The process initially used a phospholipase A 2 (PLA2) from porcine pancreas produced by R枚hm.

The enzyme degumming process greatly changes the physical properties of the resulting gums when compared with conventional degumming. The hydrolyzed gum is less
Degumming - an overview | ScienceDirect Topics
Degumming is a process for removal of phosphatides from crude soybean and other vegetable oils to improve physical stability and facilitate further processing. The phosphatides are also called gums and lecithin. Lecithin is the common name for phosphatidylcholine, but common usage refers to all of the phosphatides present in vegetable oils.
Introduction to Degumming AOCS
Crude oil obtained by screw pressing and solvent extraction of oilseeds will throw a deposit of so-called gums on storage. The chemical nature of these gums has been difficult to determine. They contain nitrogen and sugar and can start fermenting so they were at one stage thought to consist of glycolipids and proteins. Now we know that these gums c...
Degumming - Edible Oil Production
DEGUMMING Crude oils contain phospholipids, resins, trace metals. These water-soluble and water-insoluble materials must be removed from the oil. The degumming process is carried out to remove adhesives from the oil. Degumming consists of lecithin processing, filtration, blending, hydration, centrifugal separation, drying, bleaching process.
