“…Sampel ketiga sampai keenam direndam dengan air, kemudian dimicrowave 3x3 menit dan selanjutnya dibiarkan dalam keadaan tertutup selama 1, 2, 3, dan 4 minggu dengan kodenya M-R1, MR2, MR3 dan MR4 berturut-turut. Masing-masing perlakuan diukur pHnya sebelum disuling (Jok et al, 2016). Masing-masing sampel disuling menggunakan Clevenger apparatus selama 15 jam dengan perbandingan serbuk kayu gaharu dan air 1:10.…”

Minyak gaharu salah satu produk hasil penyulingan dari resin gaharu yang selain aromanya yang unik dan memiliki aktivitas biologis. Oleh karena tingginya minat serta kelangkaan sumber-sumbernya secara alamiah, peneliti berusaha menemukan cara agar proses penyulingannya lebih efisien tanpa mengorbankan kualitas. Pada penelitian ini serbuk resin gaharu diberikan pretreatmen sebelum disuling dengan menggunakan microwave dengan daya 180 Watt selama 3 x 3 menit. Selanjutnya serbuk resin tersebut direndam masing-masing 1, 2, 3, dan 4 minggu sebelum dilakukan hidrodistilasi selama 15 jam. Minyak atsiri yang dihasilkan selanjutnya dianalisa menggunakan GCMS, sedangkan aromanya diuji hedonis untuk mengetahui perlakuan mana yang paling disukai responden. Hasil penelitian menunjukkan bahwa terjadi peningkatan rendemen minyak atsiri setelah pretreatment. Ada senyawa yang konsisten muncul pada semua perlakuan termasuk kontrol seperti benzylacetone, β-selinene, alloaromadendrene, n-hexadecanoic acid, β-guaiene, dan agarospirol, sedangkan senyawa yang muncul setelah diberikan perlakuan microwave di antaranya adalah di antaranya adalah γ-gurjunene, valerenol, valencene, dibenzylacetone, α-selinene, α-guaiene, beta elemene, γ-muurolene, isocaryophyllene, ocimene, valerenal, cadinene dan dimetil octatriene. Adapun di antara senyawa di atas, yang baru muncul setelah mengalami perendaman adalah valerenal, dibenzylacetone, isocaryophyllene, ocimene, α-guaiene, β-elemene, dan γ-muurolene. Praperlakuan dengan menggunakan microwave dengan daya 180W dan perendaman sampai 2 minggu dapat meningkatkan jumlah rendemen dan keanekaragaman komponen minyak gaharu atsiri. Uji hedonik menunjukkan responden aroma minyak atsiri setelah pretreatment tidak merusak kualitas minyak gaharu.

“…As the soaking time increased, the acidity of the medium increases too as to corrode the cell wall of the agarwood chips, but over time, it may cause excessive breakage and releasing the chemical compounds to the soaking medium [23]. Further research by Jok et al [24] confirmed that longer soaking time might increase the yield but over soaking will somehow give a lower yield which can result in the wastage of the essential compounds of the agarwood chips into the soaking water. Figure 2 also shows that EP3 has the highest yield of 0.125 %, which is close to oil yield obtained from sample S14, which is 0.13 %.…”

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.
