Procedure

An aqueous solution of potassium citrate was prepared by adding 132 grams of potassium hydroxide (KOH, 85% pure) and 210 grams of citric acid monohydrate to 695 grams of distilled water. To this, 15.2 grams of acetaldehyde/diacetyl flavorant was added. After mixing, the mixture was transferred to a Niro spray dryer, which maintained an inlet air temperature of 120° C. and an outlet air temperature of 90° C. The resultant free-flowing powder was hygroscopic and collapsed in storage over night.
