DRY COMPOSITIONS CONTAINING HYDROPHOBIC AMINO ACID

摘要

An amino acid which is useful in regulating or preventing coloration caused by the combined use of saccharides with amino acids; and an amino acid which is useful as a stabilizer for dry compositions containing a proteinous pharmacologically active substance. A coloration inhibitor, which contains a hydrophobic amino acid as the essential component, adequate for preventing dry compositions containing saccharides from coloration; a method of preventing dry compositions containing saccharides from coloration characterized by using a hydrophobic amino acid; and dry compositions containing a proteinous pharmacologically active substance which further contain saccharides and a hydrophobic amino acid as a stabilizer.
