Abstract
Several aspects of the alkali refining process are poorly understood. It is not clear whether or not oil is saponified, and by what mechanism non-hydratable phosphatides (NHP) are removed from the oil. There is no systematic study on the loss of neutral oil that is entrained by the soapstock and how to minimise this loss and the possible oil loss by hydrolysis during deodorisation or steam refining is not clear either. Some fairly simple experiments will be suggested that might hopefully provide the answers.
