Agarwood oil, also known as oud oil, is a highly valuable and fragrant essential oil derived from the resinous heartwood of Aquilaria trees. The production and extraction of agarwood oil are critical processes that determine the quality, aroma, and market value of the final product. With the global demand for agarwood and oud steadily rising, understanding the intricacies of extraction methods is essential for businesses and connoisseurs alike. This article provides a comprehensive overview of two primary distillation methods used in agarwood oil production: hydrodistillation and steam distillation, highlighting their differences, benefits, and limitations.

Izindlela eziyinhloko zokukhipha amafutha abalulekile ku-agarwood ziyi-hydrodistillation kanye ne-steam distillation. Zombili lezi zindlela zisebenzisa ukushisa namanzi avuthayo ukuze zihlukanise amafutha aphumayo ezitsheni, kodwa izinqubo zazo nemiphumela zihluke kakhulu. I-hydrodistillation ibandakanya ukufaka ama-chips e-agarwood ngqo emanzini abilayo, kuyilapho i-steam distillation idlulisela umusi ku-agarwood ngaphandle kokuxhumana ngqo namanzi. Lezi zihlukaniso zendlela zithinta ukwakheka kwamakhemikhali amafutha, iphrofayili ye-aroma, kanye nokusebenza kokukhipha.

Ukudluliswa kwe-steam kuyindlela esetshenziswa kakhulu yokukhipha amafutha abalulekile emithini ehlukene. Isebenza ngokukhiqiza umusi endaweni ehlukanisiwe bese iwudlulisela emathunjini e-agarwood. Ukushisa komusi kuveza amafutha anomuthi, okwakha kabusha kube ifomu leliquidi ngemva kokupholisa. Ukudluliswa kwe-steam kuthandwa ngenxa yokukwazi ukukhipha amafutha ngaphandle kokufaka impahla eluhlaza emanzini, kugcine ezinye izakhi ezithambile ekushiseni. Nokho, ukufaneleka kwayo ekukhipheni amafutha e-agarwood kubonisa izinselelo ngenxa yezici ezihlukile zomuthi.

I-Hydrodistillation iyindlela yokukhipha evamile ebandakanya ukuvuthela ama-chips noma uthuli lwe-agarwood ngqo emanzini. Ama-volatile oils ayaphuma kanye ne-steam futhi aqoqwa ngokuhlanganiswa. Le ndlela ivumela ukuba i-agarwood ibhekane nezinga lokushisa namanzi isikhathi eside, okwenza kube lula ukuhluza izakhi ezine-resinous nokwandisa umkhiqizo we-oyili. I-Hydrodistillation ikakhulukazi iyasebenza ku-agarwood oil ngoba ingakhipha ama-molecule amakhulu futhi ayinkimbinkimbi, okwenza kube nomphumela ophakeme futhi ojulile wokunambitheka.

Ngokukhiqizwa kwama-agarwood oil, i-hydrodistillation ivame ukukhethwa ngenxa yokusebenza kwayo okuhle kokukhipha kanye nekhono layo lokugcina izakhiwo zokunambitha eziyinkimbinkimbi ezihlobene ne-agarwood esezingeni eliphezulu kanye nemikhiqizo ye-oud. Ukubekwa kwale ndlela emanzini abilayo kusiza ukukhulula ibanga elibanzi lezakhi zokunambitha, okwenza uwoyela ube nekhwalithi ephezulu futhi ube nenani elikhulu emakethe. Le njongo ibaluleke kakhulu uma kubhekwa intengo ephezulu ye-agarwood oil, lapho ikhwalithi ithonya kakhulu intengo ye-agarwood oil nge-kilogram.

Ubuchwepheshe bokuhlanza amanzi buvela ekusebenzeni kwalo okuhlangene. Ukupheka isikhathi eside kwehlisa izakhi ze-resin ye-agarwood, kukhulula ama-sesquiterpenes anzima kanye nama-chromones abalulekile ekuthandeni kwe-agarwood. Le ndlela iphinde yehlise ukulahleka kwezinto eziphumayo ezingase zishise ngesikhathi sokuhlanza ngamanzi. Njengomphumela, uwoyela we-agarwood ohlanjululiwe ubonakala unomzimba ogcwele, iphunga eliyinkimbinkimbi, kanye nokuphila isikhathi eside. Lezi zici zibalulekile kumabhizinisi afuna ukuhlinzeka ngama-oyela e-agarwood aphezulu ahlangabezana nezilindelo zamakhasimende futhi agcine inzuzo yokuncintisana emakethe yephunga eliyigugu.

Ngenkathi ukuhluza kwe-steam kusebenza kahle ezinzuzweni eziningi ezisemqoka, ukusetyenziswa kwayo ekukhishweni kwe-agarwood kubhekene nezinselelo. Ukushisa okungaqondile kanye nesikhathi sokuxhumana kwe-steam esifushane kungaholela ekukhishweni okungaphelele kwezinto ezinzima ze-resin. Ngaphezu kwalokho, ezinye izinto ezinambitheka ze-agarwood ziwumfutho wezinguquko zeshisa, okuholela ekubeni kube nephunga elilula noma eliguquliwe elingase linganelisi abathandi be-oud oil bendabuko. Ngakho-ke, i-agarwood oil ehluzwe nge-steam ingase ibonakale ingeyona eyinkimbinkimbi futhi ingase ithinte inani elibukwayo le-oyela.

Naphezu kwezithiyo zayo, ukuhluza nge-steam kungaba usizo ezimeni ezithile. Isibonelo, uma kufunwa iphrofayili yephunga elilula noma uma kuhlungwa izinqwaba ezincane ngezikhathi zokuphendula ezisheshayo, ukuhluza nge-steam kunikeza ukuhamba kahle. Ngaphezu kwalokho, kungase kuthandwe kumkhiqizo we-agarwood noma emixubeni lapho iphunga elinamandla le-agarwood elihlanzekile lingadingeki. Nokho, ekukhishweni kwe-agarwood oil ephezulu, ukuhluza ngamanzi kusala kuyisinqumo esiphezulu.

Ekuphetheni, i-hydrodistillation iyindlela ethokozisayo yokukhipha uwoyela we-agarwood ophakeme, inikeza ukusebenza kahle kokukhipha okukhulisiwe, ama-aroma anothile, kanye nokuhambisana kangcono nezilindelo zemakethe. Ngenkathi i-steam distillation inendawo yayo ezimeni ezithile, izici ezihlukile ze-resin ye-agarwood zenza i-hydrodistillation ifaneleka kakhulu ekukhiqizeni uwoyela we-agarwood kanye ne-oud ethola amanani aphezulu. Ukukhetha kokunambitha komsebenzisi kanye nesipiliyoni esithile sizohlale siba nendima, kodwa ukusuka emkhakheni wokukhiqiza kanye nebhizinisi, i-hydrodistillation inikeza izinzuzo ezibalulekile.

Ngemininingwane eyengeziwe ngemikhiqizo ye-agarwood kanye nezindlela zokukhipha, i-Guangzhou Junyi Qichen Trading Co., Ltd. inikeza uhla olubanzi lwezinto zokwakha ze-agarwood ezisezingeni eliphezulu, amafutha abalulekile, kanye nezixazululo ezenziwe ngokwezifiso. Ukuzinikela kwabo emsebenzini wobucraft kanye nokutholwa okungaguquki kubenza babe ngumlingani othembekile kumabhizinisi afuna amafutha e-agarwood aphezulu. Ungakwazihlola imikhiqizo yabonoma ufunde kabanzi ngamanani enkampani yabo ku-Mayelana Nathiikhasi.
