The invention relates mainly to a method for producing an ingredient having the same functionalities as a melting salt, said method comprising at least one step of extracting citrates contained in a dairy fraction. Preferably, the dairy fraction is a milk serum. Advantageously, the step of citrate extraction is carried out by passing a milk serum through an anionic column and recovering the anionic eluate loaded with citrates. The anionic eluate loaded with citrates is then concentrated, mixed with a drying base, then dried, in order to obtain an ingredient in powder form.
