Quality Parameters of Cymbopogon citratus Leaves During Ambient Storage

The effects of storage in different packages on the essential oil content and humidity of Brazilian lemon grass ( Cymbopogon citratus ) leaves were studied. Lemon grass leaves were dried at 50°C to moisture content of 11% (d.b.) and stored for one year in three different plastic and paper packages....

Summary:The effects of storage in different packages on the essential oil content and humidity of Brazilian lemon grass ( Cymbopogon citratus ) leaves were studied. Lemon grass leaves were dried at 50°C to moisture content of 11% (d.b.) and stored for one year in three different plastic and paper packages. Oil content and its principal compounds were isolated by the hydro-distillation method and analyzed by GC-FID as well as GC-MS every two months. The results showed a reduction in the oil content as well as a decrease in citral and myrcene in the plant for all packages during storage. Water concentration did not significantly vary during the period in the three packages.
