Abstract

The present invention relates generally to emulsan-alginate compositions and to methods of use. Methods are provided for use of emulsan-alginate compositions as drug delivery vehicles. In addition, methods are provided for use of emulsan-alginate compositions in applications requiring protein adsorption (e.g removal of protein toxins from food products or other products and solutions). The compositions of the invention avoid some of the problems seen in the art with alginate microspheres or particles.
