Methyl ethyl cellulose is a semi-synthetic polymer polysaccharide with its primary component being the cell walls of green plants and algae. Commercially it can be prepared from wood and chemically modified. It produces a solid off-white powder and when dissolved in water forms colloids which are then used as thickeners, stabiliser, foaming agent, and emulsifiers in many food products.http://www.creative-enzymes.com/product/Ethyl-Methyl-Cellulose_429.html
