Abstract
The present invention provides methods of processing lipid materials such as soapstock, wet gums and dry gums. Enzymes are utilized to catalyze hydrolysis of the lipids materials to recover fatty acids. Addition of organic acids and/or polyols improved yield of fatty acids and reduced formation of emulsion. Lipid materials can be formulated with other agricultural products as new value-added animal fee products.
Claims13
A method of producing fatty-acid-rich oil from a by-product from vegetable oil refining, the by-product being selected from a group consisting of soapstocks and wet gums, the method comprising the steps of:
- mixing the by-product with a solvent prior to a hydrolysis step, said solvent comprising glycerin;
- adding caustic to the by-product to adjust the pH of the by-product to an optimal working pH range of an enzyme selected from a group consisting of phospholipase A1, phospholipase A2, phospholipase C, lipase, and protease;
- adding the enzyme to the by-product to hydrolyze the by-product into fatty-acid-rich oil containing free fatty acids and phosphatide molecules, and to split the by-product into a fatty-acid-rich oil phase, an emulsion phase and a water phase;
- and
- separating the fatty-acid-rich oil phase.
