Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method for improving physical properties of powdery goods without deteriorating the characteristic quality of the powder raw material or complicating the process, causing little deposition of the powder to a production facility in spray-drying and giving a powder having excellent fluidity and caking resistance. SOLUTION: Powdery goods are produced by the spray-drying of a water-containing raw material containing a hygroscopic component, wherein the spray drying is performed by adding ethanol to the water-containing raw material containing a hygroscopic component.
