An object of the present invention is to provide an acetate salt compound which is capable of reducing acetic acid odor and further capable of suppressing the decomposition of glucose even when it is made to coexist with glucose. A higher order acetate salt compound containing acetic acid-sodium acetate mixed crystal, in powder X-ray diffraction measurement, diffraction peak A at 2 = 8.8 0.2 , and 2 = 22.3 0. A diffraction peak B is observed at 2 and the ratio Ia / Ib of the integrated intensity Ia of the diffraction peak A and the integrated intensity Ib of the diffraction peak B is less than 1.447 effectively suppresses volatilization of acetic acid It is possible to reduce acetic acid odor, and it is possible to suppress the decomposition of glucose even if it coexists with glucose. 本発明の目的は、酢酸臭を低減でき、更にブドウ糖と共存させてもブドウ糖の分解を抑制できる酢酸塩化合物を提供することである。 酢酸－酢酸ナトリウム混晶体を含む高次酢酸塩化合物であって、粉末Ｘ線回折測定において、２θ＝８．８°±０．２°に回折ピークＡ、及び２θ＝２２．３°±０．２°に回折ピークＢが認められ、当該回折ピークＡの積分強度Ｉａと当該回折ピークＢの積分強度Ｉｂの比率Ｉａ/Ｉｂが１．４４７未満である化合物は、酢酸の揮発を効果的に抑制でき、酢酸臭の低減が可能であり、しかもブドウ糖と共存させてもブドウ糖の分解を抑制できる。
