The invention discloses corn peptide salt, and belongs to the field of composite salt seasonings. The corn peptide salt consists of 14-19 parts of corn peptide powder, 3-7 parts of hydroxypropyl methyl cellulose, 4-9 parts of sodium glutamate, 84-98 parts of table salt, 5-8 parts of chicken powder and 7-10 parts of a yeast extract. The preparation method of the corn peptide salt comprises the following steps: respectively screening the corn peptide powder, the hydroxypropyl methyl cellulose, the chicken powder and the yeast extract through a fine sieve of 60-80 meshes; then baking the screened corn peptide powder, the screened hydroxypropyl methyl cellulose, the screened chicken powder and the screened yeast extract at the temperature of 60 DEG C, and removing water; and uniformly mixing and stirring the dried corn peptide powder, the dried hydroxypropyl methyl cellulose, the dried chicken powder, the dried yeast extract, sodium glutamate, table salt, peptone and an EDTA iron chelate at a room temperature so as to obtain the corn peptide salt. The components of the corn peptide salt disclosed by the invention are simple and easy to obtain; the corn peptide salt is rich in components of corn peptide, yeast extracts and the like, is rich in nutrition, contains essential amino acid needed by human bodies, and provides nutrition of amino acid, peptide and the like. The making method is simple and convenient, and easy to control, and the corn peptide salt is convenient for batch production and popularization.
