Provided is a composition in which a food can be present stably and which has various use properties so as to be able to be used in various use applications. A composition containing microparticulate complexes of a food, the composition being characterized in that: (a) the largest particle diameter before an ultrasonic treatment is larger than 100 μm; (b) when the ultrasonic treatment is carried out, the largest particle diameter after the treatment decreases by 10% or more compared with that before the treatment; (c) when the ultrasonic treatment is carried out, the mode diameter after the treatment is 0.3 to 200 μm inclusive; and (d) when 10000 microparticles and/or microparticulate complexes in the composition before the ultrasonic treatment are analyzed with a particle form image analysis device, the 10
