Sorbic acid-containing powder or granules

Abstract

Sorbic acid-containing powder or granules free from scatterability and rapidly soluble in water consisting of 5-90% by weight of finely divided sorbic acid with particle diameter of 50.mu. or less, 10-95% by weight of an easily water-soluble substance which is a solid at normal temperature and 0-2% by weight of hydrophilic surface active agent, characterized by having particle diameter of 300.mu. or more. The above sorbic acid-containing powder or granules can be obtained by drying after making powder or granules having particle diameter of 300.mu. or more from a mixture consisting of finely divided sorbic acid with particle diameter of 50.mu. or less, an easily water-soluble substance which is solid at normal temperature, water and/or an aqueous organic solvent and optionally, a hydrophilic surface active agent, or by making powder or granules having particle diameter of 300.mu. or more from the dry mixture after drying said mixture.
