In this research, the changes on these seeds during storage:
total oil, volatile oil, and the major components of volatile oils were
determined. A decrease in the total and volatile oils and all
components of volatile oils were found.
The identification of the cumin oil composition was determined
qualitatively and quantitatively by GC, using standard compounds.
The components of the cumin seed oil (Cuminaldehyde, p-cymen
and β-penine) were matched with the standard compounds.
The factors effect on some components of cumin seed volatile oil
were studied.
The effects of time and temperature on the cumin seeds
components were studied, the results have been shown that the total
oil and volatile oil and its main components decreases with the
passing of time and with the increasing of temperature.
