PURPOSE:To provide a simple process for suppressing degradation of wet sorbic acid cake mixed with water and/or solvent and produced in a sorbic acid production process, by sealing the wet cake with an inert gas. CONSTITUTION:Wet sorbic acid cake mixed with water and/or solvent is sealed in a system having an oxygen concentration of <=15vol% by introducing an inert gas such as nitrogen, carbon dioxide, argon, etc., into the system. The method is remarkably effective in preventing color development and aging of an alkali metal sorbate produced by neutralization of sorbic acid. Sorbic acid has antimold action and is useful as an additive for preservation of foods.
