摘要

Abstract

Cinnamon essential oil with many bioactivities is an important raw material for the production of various chemicals

and the conventional hydrodistillation (HD) for cinnamon oil extraction always require a longer extraction time. In this work

ultrasound-assisted hydrodistillation extraction (UAHDE) technique was employed to enhance the extraction efficiency of essential oils from cinnamon barks. The parameters with significant effects on the essential oil extraction efficiency (ultrasound time

ultrasound power

extraction time

liquid-solid ratio) were optimized

and the proposed UAHDE was compared with the conventional HD extraction in terms of the extraction time

extraction yield

and physicochemical properties of extracted oils. Compared to the HD extraction

the UAHDE resulted in a shorter extraction time and a higher extraction yield. Using GC-MS analysis

the UAHDE provided more valuable essential oil with a high content of the vital

trans

-cinnamaldehyde compounds compared with the HD. Scanning electron micrograph (SEM) confirmed the efficiency of ultrasound irradiation for cinnamon oil extraction. In addition

the analysis of electric consumption and CO

emission shows that the UAHDE process is a more economic and environment-friendly approach. Thus

UAHDE is an efficient and green technology for the cinnamon essential oil extraction

which could improve the quantity and quality of cinnamon oils.
