| Popis: |
The total amino acid and i-malic acid content of 61 samples of commercial California-Arizona lemon juice and lemon juice concentrates were studied. In characterizing these juices, relationships were observed between the natural citric acid content and the amounts of their total amino acids and l-malic acid. Total amino acids were determined by formol titration, while the l-malic acid was determined by measuring the optical rotation of a uranylmalate complex. Paper chromatograms of the individual amino acids are used to supplement these methods of analysis for characterizing lemon juice. |
