“…Before the Agarwood tree is processed into oil, it must be extracted and went through some analyzing process to sort out the quality. The chemical composition of agarwood has been studied extensively in [4] [5] [9]. The chemical compound found in Agarwood oil is different when a different extraction method and analyzing method is applied.…”

“…Agarwood oil can be extracted using Hydrodistillation (HD), supercritical fluid extraction (SFE), Headspace-Solid Phase Microextraction (HS-SPME) with fiber coating [5], [7]- [9] and Polydimethylsiloxane (PMDS) extraction method [10]. However, hydrodistillation is the most used method for extraction.…”

“…However, studies show that it has questionable accuracy because the human nose has limitation because which easier to get fatigued when used to smell for a long period and exposed to a high volume of a sample [1]. Nowadays, Gas chromatography flame-ionization detector (GC-FID) and gas chromatography-mass spectrometer (GC-MS) are the common methods applied to analyze an Agarwood oil [5], [7]- [9]. Even though GC techniques are the most reliable methods, but analysis cannot be carried out in situ because GC was not portable [11][12].…”

This study classifies the quality of local Agarwood oil based on the absorbance intensity of aromatic alkane (pleasant odors), which is represented by the C-H bond. Agarwood is a valuable tree species because of its widely used as perfumes and in traditional and religious ceremonies. In this research article, the absorbance intensity of the C-H bond was carried out using Cary 630 FTIR spectrometer. In this research article, the quality of Agarwood oil was successfully graded based on the absorbance intensity of the C-H bond measured at 3417.68 nm wavelength.

“…Hydrodistillation is mostly applied by the commercial agarwood industries in Malaysia; even though this method is the simplest method, it is not effective in term of both timeand energy-consumption. The conventional method has major drawbacks in the operating process where the soaking may take 7 to 14 days [10] and another 4 to 10 days for the extraction completion. The long extraction times may influence the loss of some volatile fragrance constituents caused by the thermal degradation resulting in low oil yield [11], [12].…”

Agarwood oil was extracted from a pre-treated agarwood chip soaked in a specific enzyme concentration of 1 %, 3 % and 5 % respectively. The effect of soaking time was also investigated by applying soaking period in the range of 3 to 14 days. Hydrodistillation was carried out using the Clevenger-type apparatus to obtain the essential oil of agarwood chips. Subsequently the quality of the oil and the identification of its oil compounds were analyzed using GC-MS. The morphology of agarwood chips prior to hydrodistillation was characterized using scanning electron microscope (SEM). The SEM results of enzymatic pre-treated sample showed an obvious change in the cell morphology as compared to the sample with standard soaking of 6 days. The highest yield of oil with the amount of 0.125 % is produced from the sample pre-treated with 3 % enzyme concentration as compared to 0.065 % of oil yield from the non-pre-treated sample employing similar soaking days. The GC-MS analysis revealed a total of 335 compounds from all samples of agarwood oil and similar compounds were found in the standard soaking and enzymatic pre-treated samples. Caryophyllene, Gurjunene, and Alloaromadendrene that contributes to the unique odour of agarwood oil are found mostly in all samples. Thus, the enzymatic pre-treatment indicates a comparable yield and oil quality and it is achievable even with a reduced soaking time of 6 days as compared to standard 14 days.

“…Several methods can be applied to identify the resin content in agarwood such as Gas Chromatography-Mass Spectrometry, Gas Chromatographyolfactometry, solid-phase micro-extraction and an electronic nose (Pripdeevech et al 2011;Hashim et al 2014;Lias et al 2015Lias et al , 2016Ahmaed et al 2017). The application of an electronic nose is more affordable because it is low-cost, has small dimensions and a low power consumption.…”

The aim of the present study is the development of an electronic nose system prototype for the classification of Gyrinops versteegii agarwood. The prototype consists of three gas sensors, i.e., TGS822, TGS2620, and TGS2610. The data acquisition and quality classification of the nose system are controlled by the Artificial Neural Network backpropagation algorithm in the Arduino Mega2650 microcontroller module. The testing result shows that an electronic nose can distinguish the quality of Gyrinops versteegii agarwood. The good-quality agarwood has an output of [1 –1], while the poor-quality agarwood has an output of [–1 1].
