Date Jun. 9, 1994Sulfited fatty compounds having a reduced content of free hydrogen sulfite are prepared by blowing unsaturated fatty compounds in an oxygen atmosphere at 100 DEG C. to 150 DEG C., sulfiting the blown fatty compounds with sodium metabisulfite, and subsequently fixing unreacted hydrogen sulfite as sulfosuccinic acid ester by aftertreatment with maleic acid esters, and optionally, a basic material.
