Abstract: Disclosed are methods of preparing PUFA-, lipid-soluble vitamin-, lipid-soluble medicament-encapsulated, or other lipid-soluble molecules micelles that enhance shelf life and prevent oxidation by inducing a Maillard reaction between a reducing sugar and a lipid emulsifying agent having at least one amino group in the presence of a PUPA, lipid-soluble vitamin or lipid-soluble medicament. Method steps include: mixing a reducing sugar, and a PUPA, lipid-soluble vitamin or lipid-soluble medicament, with a lipid emulsifying agent having at least one amino group and a purity of at least 95 wt %, and heating the resulting micelle mixture for sufficient time at a sufficient temperature and under reduced pressure below 1 atm with sufficient moisture so that a Maillard reaction occurs between the lipid amino groups and the reducing carbohydrate to provide a Maillard reaction product coating on the micelles that is effective to prevent oxidation of the PUPA, lipid-soluble vitamin or lipid-soluble medicament.

Abstract: A method of preparing rumen-protected polyunsaturated fatty acids (RuPUFAs) for use in ruminant feeds by inducing the Maillard reaction between a reducing carbohydrate source and de-oiled lecithin in the presence of a PUFA under reduced pressure conditions is disclosed. Products made by the process, as well as methods for enhancing performance, assisting the induction of pregnancy, alleviating inflammation, modulating fetus growth, improving immune system function, and modulation of the fatty acid composition of meat and milk of ruminant animals are also disclosed.
