Methylcellulose: Small Scale Suppliers
But beware… you are looking for methylcellulose (not hydroxypropyl methylcellulose, not sodium carboxymethylcellulose).
Its E number is E461. The type you need should have a viscosity of 4,000 to 50,000.
If in doubt, try emailing me.
You will also find methylcellulose on eBay. Look for methylcellulose, gelation temperature 50-55C and probably safest to go for Methocel MX. BUT watch out for shipping costs!
Watch out too for suppliers who offer methylcellulose, but the product is actually hydroxypropyl methylcellulose. This is good stuff for gluten free bread but NOT for vegan burgers
