Procedure

An aqueous solution of calcium citrate was prepared by combining 56.1 grams of calcium oxide with 210 grams of citric acid monohydrate in 532 grams of water. The mixture immediately gelled and later solidified rendering it impossible to add the acetaldehyde/diacetyl flavorant, or to spray dry the mixture.
