Procedure

1.45 grams of trisodium citrate dihydrate in 20 ml of distilled water was added to 18,900 grams of xanthan broth to give an equivalent citric acid concentration of 50 ppm; i.e., citric acid concentration of 50 ppm was prepared by adding 77 ppm trisodium citrate dihydrate. The citric treated xanthan sample in a 5 gallon polyethylene carbuoy was then vigorously agitated in a New Brunswick rotary shaker for 1 hour to insure proper mixing.
