A method of extracting nutrients from a plant includes the steps of: pulverizing a water soluble nutrient-based plant part of a first plant material of the plant so as to form a first pulverized plant part; pulverizing a lipid soluble nutrient-based plant part of a second plant material of the plant so as to form a second pulverized plant part; subjecting the first pulverized plant part to a distillation so as to obtain a distillate and a first residue that contains a water soluble nutrient; and immersing the second pulverized plant part in the distillate to form a first mixture followed by distillation of the first mixture, so as to obtain a second residue that contains a lipid soluble nutrient.

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.
