METHODS FOR DEGUMMING OILS

摘要

Processes and systems are provided for effectively degumming vegetable oils with the use of an acid and base pretreated mixture of vegetable oil. The pretreated mixture is subjected to compression and one or more intervals of explosive decompression of the compressed mixture to form a degummed vegetable oil. Also provided are compression and decompression rates and conditions that can be used to effectively degum vegetable oil to achieve reduced levels of phosphorus and metals such as iron, calcium and magnesium.

主权项

1. A process for hydration of non-hydratable phospholipids in a vegetable oil comprising:
a) mixing an acid and the vegetable oil to form an emulsion; b) mixing a base with the emulsion to obtain a pretreated mixture, the pretreated mixture having droplets containing acid and droplets containing base; c) compressing pretreated mixture to reduce the volume of the droplets containing acid and the droplets containing base, thereby forming a compressed mixture; d) decompressing the compressed mixture, said decompressing step carried out in the range of 1×105 MPa per second to about 3×106 MPa per second, causing the droplets containing acid and the droplets containing base to burst into smaller droplets.
