Identification and comparison of volatile aroma constituents of Salacca zalacca (Gaertn.) voss extracted by steam distillation, solvent extraction and supercritical fluid extraction methods
Salacca zalacca (Gaertn.) Voss (salak fruit or snake fruit) is a species of palm tree native to Southwest Java and North Sumatra in Indonesia. It is known as one of the exotic fruits in Malaysia. It has a reddish-brown scaly skin with pleasant pineapple, pear and banana-like aromas. Due to its pl...

| description |
Salacca zalacca (Gaertn.) Voss (salak fruit or snake fruit) is a species of palm tree native to
Southwest Java and North Sumatra in Indonesia. It is known as one of the exotic fruits in
Malaysia. It has a reddish-brown scaly skin with pleasant pineapple, pear and banana-like
aromas. Due to its pleasant aroma, S. zalacca has potential in perfumery and pharmaceutical
industries. The volatile aromas of plants are usually extracted by conventional extraction
methods such as steam distillation and solvent extraction methods. These methods are
laborious, have incomplete extraction process, require long extraction time, and produced
a lot of toxic chemical wastes. New extraction technique introduced by the researcher to
overcome these limitations is supercritical carbon dioxide extraction method (SC-CO2). This
technique is available to extract the volatile aroma of the plants. It is rapidly gaining attention
due to its superior benefits compared to the conventional extraction methods. It is considered
as a green extraction technique because it is renewable, produces little to no toxic wastes
and has short extraction time. In this study, S. zalacca were extracted by steam distillation,
solvent extraction and SC-CO2. Steam distillation was not a suitable extraction method for
S. zalacca as it produced inorganic compound. The percentage yields of SC-CO2 samples
were higher (10 MPa, 30 oC: 0.2704 %; 25 MPa, 50 oC: 0.3634 %; 40 MPa, 70 oC: 0.2635 %)
than the hexane (0.0511 %) and dichloromethane (0.1358 %) extractions but lower than the
diethyl ether (0.5692 %) solvent extraction. SFE has shorter extraction time and produced
little chemical waste compared to solvent extraction methods. GC-MS analysis of the extracts
from both extraction methods should be conducted to identify and compare the volatile aroma
constituents present in solvent extraction extracts and SFE extracts. |
