[Object] An object of the present invention is to provide a technique that allows commercialization of a carbonated beverage containing soybean powder and/or soymilk stored in a bottle in a condition that provides preservation stability for a long period of time. [Method for Achieving the Object] By storing a carbonated beverage containing soybean powder and/or soymilk in a bottle having a light transmittance of 10% or less for a wavelength of 250 to 650 nm, deterioration of the flavor of the carbonated beverage containing soybean powder and/or soymilk can be suppressed and long-term preservation stability can be maintained.
