The emulsified food product has a small (21) Appl. No.: 12/853,944 oil droplet size while also providing increased viscosity in a stable emulsion having a high fat content. The method (22) Filed: Aug. 10, 2010 achieves the increased viscosity and small oil droplet size by use of high pressure homogenization with enzyme-modified Related U.S. Application Data egg with a high fat content. The emulsified food product can be used directly as a mayonnaise product or combined with further ingredients to provide other products, including may (60) Provisional application No. 61/371,973, filed on Aug. onnaise products with lower fat content but desirable creamy 9, 2010. mouthfeel and Viscosity.
