Interesting problem and some of the responses. Several mentions of polyacrylate - which is a well known, quite effective calcium sulfate precipitation inhibitor. Look at PAA of ~3000 molecular weight...you might also test a blend with a higher molecular weight - maybe approaching 10,000. The MWs do not need to be tight...but the 3,000 realm is generally better known for inhibition performance.
Years ago a Amino amino hexamethylene phosphonic acid was also rated quite highly as a calcium sulfate inhibitor.

Do you any of the PAA ~3000 MW suppliers who have a food grade and
pharmaceutical grade products.
