FIELD: food processing industry. SUBSTANCE: foam-extinguishing composition has polyglycerin esters with fat acids with number of hydrocarbon atoms of 12 - 20 and water under following ratio of components, mass %: polyglycirin esters with fat acids 40 - 50, water 50 - 60. The composition is produced by polymerization of glycerin with following etherification of semi-finished product with fat acid and dispersion in definite amount of water. Implementation of the composition allows to accelerate foam extinguishing process twice as compared with known substance under uniform usage of substances and so to increase effectiveness of foam extinguishing process, to expand range of domestic foam-extinguishing products and also to decrease their cost. EFFECT: increased effectiveness of foam-extinguishing process, decreased their cost. 2 tbl
