ALPHA-PINENE Usage And Synthesis
| Uses | β-Pinene is also used in flavor compositions, partly as ingredient in artificial Lemon and Nutmeg oils, partly as component of such type flavors. The concentration in the finished product will be about 15 to 150 ppm. alpha-Pinene has a more balsamic taste, while be~a-Pinene, less suitable for flavors, has a dry-woody character. |
| Definition | ChEBI: (-)-alpha-pinene is an alpha-pinene. It is an enantiomer of a (+)-alpha-pinene. |
| Production Methods | beta-pinene can be produced 1) by isolation from American Turpentine(minor component).2) it is also possible to convert alpha-Pineneinto bera-isomer. |
| Biotechnological Production | Pure alpha-pinene is obtained by distillation of turpentine oils. |
| General Description | Alpha-pinene appears as a clear colorless liquid with a turpentine odor. Flash point 91 °F. Less dense than water and insoluble in water. Vapors are heavier than air. Used as a solvent. |
| Contact allergens | Alpha-pinene is the major constituent of turpentine(about 80%). It exists in levogyre form in Europeanturpentine and in dextrogyre form in turpentine foundin North-Americans. Sensitization occurs mainly inpainters, polishers, and varnishers, and in those in theperfume and in the ceramics industry. |
