Abstract
This invention relates to a method of producing sucrose fatty acid ester granules by the fluidized bed granulation and drying technique and consists in forming a fluidized bed comprising a sucrose fatty acid ester powder at a temperature not exceeding 60.degree. C., spraying the fluidized bed with an aqueous sucrose fatty acid ester solution having a concentration of 3-20% by weight, as a binder, and then drying the sprayed fluidized bed, to thereby cause granulation. In accordance with the invention, the disintegration of sucrose fatty acid ester granules during granulation and drying can be prevented and highly pure sucrose fatty acid ester granules can be obtained. The sucrose fatty acid ester granules produced by the method of the invention are incapable of forming a cloud of fine powder, and have very good dispersibility and solubility.
