High Viscosity Methylcellulose E461, or methyl cellulose is a thickener and emulsifier. Methylcellulose is a compound derived from cellulose. This white hydrophilic powder dissolves ONLY in cold liquid to form a clear viscous solution or gel. A solution of methylcellulose will turn solid when heated and since it is completely thermo-reversible will turn back to liquid when cooled. It is also used as a stabilizer in ice cream to help prevent the formation of ice crystals during freezing or re-freezing after a thaw. Like cellulose this component is non toxic, and not allergenic. Methylcellulose HV is High Viscosity (approximately 4500 cps. in 2% solution). Cold water soluble, Methylcellulose HV will gel when heated to temperatures from 132F to 148F. Our LV and HV methylcellulose can be mixed together at different ratios to achieve desired effects. This product is certified Kosher (Pareve) by the Orthodox Union
