Abstract | ||||
The effect of post harvest treatment and the hump beetle , Gibbium psylloids (Zemp.), on the quality and quantity of dry chamomile flower heads was studied. Results, after storage period of two years, revealed that the glass jar packing received the lowest insect population, followed by plastic net then card box, while the highest insect population was observed in polyethylene bag. The highest weight loss of dry chamomile flower heads occurred in plastic net and the lowest in glass jar, at the end of the second year of storage. The essential oil percentage decreased by increasing the storage period in all experimental packages. Acid number decreased in all package except in polyethelene bag, which recorded an increase in acid number after two years storage. | ||||
