US 11,247,964 B2 · Method of processing phospholipid based lipid materials

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 feed products. Further, a process for concentrating nitrogenous compounds such as choline, inositol, ethanolamine and serine from phospholipid materials obtained as byproducts from vegetable oil refining is provided. The process involves performing hydrolysis of the gum based products in the presence of an alcoholic solvent and acid catalyst. Post hydrolysis, gums breakdown to oil and water phases which are further separated and concentrated. These concentrated products may be further fractionated to concentrate individual nitrogenous compounds.

Dependent claims

A method of processing a gum feedstock comprising at least one phospholipid material that comprises at least one nitrogen-based material, comprising:

hydrolyzing said feedstock with an acid catalyst in the presence of an alcoholic solvent to form a first phase and a second phase, said first phase comprising oil and said second phase comprising phospholipid material containing at least one nitrogen-based material;
and
further concentrating said nitrogen-based material from the second phase;
wherein said gum feedstock is selected from the group consisting of wet gums, dried gums, enzymatic wet gums, lecithin, and vegetable oil phospholipids.
