Abstract
In order to provide a spray dry method capable of producing a dry powder retaining the savor and flavor of a raw material and having solubility without any thermal deterioration, at a mass scale, a method for producing a dry powder keeping savor and flavor from a hydrous liquid material containing a savory and flavorful component and, preferably, a hygroscopic component by spray drying is disclosed, the method including spray drying the hydrous liquid material at the microfine liquid droplet state in gas atmosphere at the outlet temperature of a spray dryer at 20 to 90° C. and the outlet relative humidity of 1% RH to 40% RH, to prepare a dry powder of a mean particle size of 0.1 μm to 15 μm.
