This application relates generally to the processing of egg protein isolates for use in various food, sports nutrition and nutraceutical applications, methods of making egg protein isolates, and apparatus for making egg protein isolates. More particularly, the application relates to a method of deflavoring egg products and concentrating the protein content to. The method can include providing liquid egg; deashing the liquid egg; concentrating the liquid egg; and desugaring the liquid egg, wherein deashing is accomplished at a pressure of less than 100 psi; and optionally the volume of water used is 0.5 to 7 diafiltration volumes.

Disclosed are novel compositions containing the egg yolk protein phosvitin or peptide fragments thereof. The compositions are substantially free of mineral ions chelated to the phosvitin protein or peptide fragments thereof. The compositions may be used in the formulation of products, including food products, personal care products, or pharmaceutical products, for example, to preserve the products.

The present invention addresses the problem of providing an albumen hydrolysate that has emulsifiability, emulsion stability and heat coagulability. An albumen hydrolysate obtained by hydrolysis of albumen with a protease, wherein the dry weight of a precipitate formed by adding nine times the amount of 0.4 M trichloroacetic acid (TCA) to the albumen hydrolysate is 60% or more relative to the dry weight of albumen treated in the same manner.

The present invention provides a method of preparing an edible oil-in-water emulsion having a pH in the range of 3.0 to 5.0 and comprising 30-78 wt. % of oil, 65-20 wt. % water and 0.5-6 wt. % egg yolk proteinaceous component by dry weight, said egg yolk proteinaceous component consisting of a combination of low-density lipoprotein (LDL), livetin, high-density lipoprotein (HDL), and phosvitin, said method comprising the steps of: a. increasing the pH of a liquid aqueous mixture comprising a first egg yolk plasma fraction to a pH of at least 9 and keeping the liquid aqueous mixture at said pH for 1-300 minutes followed by decreasing the pH of the mixture to a pH of 7 or less to produce an alkaline treated egg yolk plasma liquid comprising alkaline treated egg yolk plasma fraction; b. preparing a first pre-emulsion by combining oil, water, egg yolk granules fraction and optionally a second egg yolk plasma fraction; c. combining the alkaline treated egg yolk plasma liquid with the pre-emulsion to produce a second pre-emulsion; and d. homogenizing the second pre-emulsion to obtain an oil-in-water emulsion;
wherein the egg yolk proteinaceous component of the oil-in-water emulsion has the following composition: 60-75 wt. % LDL; 8-14 wt. % livetin; 11-18 wt. % HDL; 2-5 wt. % phosvitin.
