Dehydrated mashed potato which does not turn sticky on reconstitution contains a small amount, e.g. 0.05-1%, on the dry weight, of a natural gum such as carragheen, algin, pectin, low-methoxyl pectin, guar gum, karaya gum, gum arabic, gum tragacanth, gum agar, locust bean gum or gum acacia. The dehydrated mashed potato may contain also a starch-complexing agent, which forms a hydrophobic substance with the amylose of starch, and renders starch incapable of forming cohesive gel structures. 0.05-1%, on the dry weight, of the starch-complexing agent may be used. The starch-complexing agent is exemplified by higher fatty acids, i.e. fatty acids of 8 or more carbon atoms, e.g. lauric, myristic, palmitic, stearic, oleic and linoleic acids and the mixed fatty acids obtained by hydrolysis or natural fats and oils or such fats and oils hydrogenated, sodium, calcium, aluminium and magnesium salts of such fatty acids, mono- and di-glycerides of such fatty acids, mono- and di-esters of sucrose and such fatty acids, such fatty acid esters of an inner ether of a hexitol, condensation products of ethylene oxide with mono- or di-esters of such fatty acids with sorbitan and mannitan, lactic acid esters and acetyl tartaric acid esters of mono- and di-glycerides of such fatty acids, a lecithin, a cephalin or a lipositol. The natural gum may be incorporated in the form of a complex with such a fatty acid and a polyvalent metal, e.g. the substance obtained by adding a water-soluble calcium, magnesium or aluminium salt to an aqueous preparation of the fatty acid or its sodium or potassium salt and the gum or its sodium or potassium salt, 0.1-2%, on the dry weight, of the complex being used. If the gum is added to the mashed potato before dehydration, a small amount, e.g. 0.1-2%, on the dry weight, of a higher fatty acid triglyceride, e.g. cottonseed, coconut, peanut or maize oil or such an oil hydrogenated may be added.
