PROBLEM TO BE SOLVED: To provide the component of a thickening composition which is used as a thickness adjuster or the like, is capable of preventing formation of lumps, is further improved in dispersibility compared to heretofore and is easy to work without needing to consider the influence of binder addition amount on composition when needing granulation in production of the thickening composition.SOLUTION: There is provided a metallic salt-containing starch decomposition product used as the component of a thickening composition including a thickening polysaccharide and improved in dispersibility. The metallic salt-containing starch decomposition product is produced by pulverizing a solution containing a starch decomposition product and a metallic salt which at least one selected from the salts of calcium, sodium, potassium and magnesium.SELECTED DRAWING: None
