PROCESS FOR IMPARTING IMPROVED FUNCTIONAL PROPERTIES TO A SINGLE-CELL PROTEIN MATERIAL AND HOMOGENIZED SINGLE-CELL PROTEIN MATERIAL THEREOF

摘要

The present invention provides a process f or homogenizing a single-cell protein material said process comprising the step of homogenizing an aqueous slurry of the single-cell protein by subjecting it to total pressure drop in the range of from 40 MPa to 120 MPa (400 to 1200 bar), wherein said single-cell protein material is a microbial culture comprising methanotrophic bacteria optionally in combination with one or more species of heterotrophic bacteria. The resulting homogenized protein material has excellent f unctional properties and f inds particular use in the preparation of f ood products, f or example as a gelling or emulsif ier.
