Anti-caking agent can be either cellulose ("sawdust"), potato starch, or calcium sulfate

I know you put it in quotes, but only about 50% of sawdust is cellulose. The remainder is hemicellulose, lignin, resins, and oils. Some shredded cheese use pure cellulose as an anti-caking agent, not sawdust.

I nevertheless find pure cellulose as a food additive very unpleasant.
