In addition to being highly anticorrosive, the melanoidins of the present invention are environmentally friendly and non-toxic, and can be found in animal food and in human foodstuffs. ## Claims ### Claim 1 A method of reducing the corrosion caused by a chloride salt, the method comprising the steps of: obtaining a molecular weight fraction of a product containing melanoidins, wherein the molecular weight fraction comprises melanoidins having a molecular weight greater than or equal to 12,400; forming an aqueous solution including the molecular weight fraction of a product containing melanoidins; and applying the solution to a metal surface, wherein the molecular weight fraction of a product containing melanoidins reduces corrosion at the metal surface caused by the chloride salt. ### Claim 2 (depends on 1) The method of claim 1, wherein the metal surface contains iron. ### Claim 3 (depends on 1) The method of claim 1, wherein the product containing melanoidins is selected from the group consisting of sugar cane and sugar beets. ### Claim 4 (depends on 1) The method of claim 1, wherein the product containing melanoidins is selected from the group consisting of molasses, corn steep liquor, brewers condensed solubles, and distillers condensed solubles. ### Claim 5 (depends on 1) The method of claim 1, wherein the metal surface is a roadway. ### Claim 6 (depends on 1) The method of claim 1, wherein the metal surface is an oil well surface. ### Claim 7 (depends on 1) The method of claim 1, wherein the chloride salt is at least one selected from the group consisting of sodium chloride, magnesium chloride, calcium chloride, and potassium chloride. ### Claim 8 (depends on 1) The method of claim 1, wherein the chloride salt is an industrial brine. ### Claim 9 (depends on 1) The method of claim 1, further comprising the step of adding a carbohydrate having a molecular weight in the range of 180 to 1500 to the solution, wherein said carbohydrate is at least one selected from the group consisting of glucose, fructose and higher saccharides based on glucose and/or fructose and mixtures thereof. ### Claim 10 (depends on 1) The method of claim 1, further comprising the step of adding a thickener selected from the group consisting of cellulose derivatives and carbohydrates in the range of 60,000 to 1,000,000 for cellulose derivatives and 10,000 to 50,000 for carbohydrates to the chloride salt. ### Claim 11 An anticorrosive composition comprising: water; a chloride salt; and water soluble solids, the water soluble solids comprising a molecular weight fraction of a product containing melanoidins, wherein melanoidins have a molecular weight greater than or equal to 12,400 and comprise at least 1.99% by weight of the water soluble solids. ### Claim 12 (depends on 11) The anticorrosive composition of claim 11, wherein the product containing melanoidins is selected from the group consisting of sugar cane and sugar beets. ### Claim 13 (depends on 11) The anticorrosive composition of claim 11, wherein the product containing melanoidins is selected from the group consisting of molasses, corn steep liquor, brewers condensed solubles, and distillers condensed solubles. ### Claim 14 (depends on 11) The anticorrosive composition of claim 11, wherein the chloride salt is at least one selected from the group consisting of sodium chloride, magnesium chloride, calcium chloride, and potassium chloride. ### Claim 15 (depends on 11) The anticorrosive composition of claim 11, wherein the chloride salt is an industrial brine. ### Claim 16 (depends on 11) The anticorrosive composition of claim 11, further comprising a carbohydrate having a molecular weight in the range of 180 to 1500, wherein said carbohydrate is at least one selected from the group consisting of glucose, fructose and higher saccharides based on glucose and/or fructose and mixtures thereof. ### Claim 17 (depends on 11) The anticorrosive composition of claim 11, further comprising a thickener selected from the group consisting of cellulose derivatives and carbohydrates in the range of 60,000 to 1,000,000 for cellulose derivatives and 10,000 to 50,000 for carbohydrates to the chloride salt. ### Claim 18 (depends on 11) The anticorrosive composition of claim 11, wherein the melanoidins have a molecular weight greater than or equal to 12,400 and comprise at least 6% by weight of the water soluble solids ### Claim 19 An anticorrosive composition comprising: water; a chloride salt; and water soluble solids, the water soluble solids comprising a molecular weight fraction of a product containing melanoidins, wherein melanoidins have a molecular weight greater than or equal to 10,000 and comprise at least 10% by weight of the water soluble solids.
