    A granulated product of potassium sorbate has an overall pore volume of 0.3 ml/g or less, has an Na content of 450 ppm or less, or has an overall pore volume of 0.4 ml/g or less, or a granule hardness of 15% or less, and an Na content of 1000 ppm or less. The granulated product is obtained, for example, by granulating a potassium sorbate aqueous solution through fluidized bed granulation drying, by neutralizing sorbic acid with a potassium sorbate having a molar ratio of Na to K (Na/K) of 0.0024 or less to yield potassium sorbate, and granulating the potassium sorbate, or by neutralizing sorbic acid with a potassium sorbate having a molar ratio of Na to K (Na/K) of 0.006 or less to yield potassium sorbate, and moisture-conditioning 100 parts by weight of the potassium sorbate with 1 to 8.5 parts by weight of water and 1 to 8 parts by weight of a water-soluble organic solvent and subjecting the resulting mixture to extrusion granulation. The granulated product of potassium sorbate has a highly stable hue over time.
