The last solid portion obtained from said treatment can be used directly as phosphate fertilizer, potassium fertilizer, or phosphate-containing and potassium-containing mixed fertilizer. The elution time of any protein is then be predicted by first creating a vector by assigning dimensional values for the elution time of amino acids of at least one hypothetical peptide and then calculating a predicted elution time for the vector by performing a multivariate regression of the dimensional values of the hypothetical peptide using the dimensional values of the known peptides.
