Uvavanyo oluqhelekileyo lwe-oyile lusetyenziswa njengendlela yokuqinisekisa umgangatho wemveliso, ukucoceka kunye nokunceda ukuchonga ubukho bezinto eziphilayo.
Phambi kokuba i-oyile ezibalulekileyo zivavanywe, kufuneka kuqala zitsalwe kumthombo wesityalo. Kukho iindlela ezininzi zokutsalwa, ezinokuthi zikhethwe ngokuxhomekeke kwiyiphi inxalenye yesityalo esiqulethe ioli eguqukayo. Ii-oyile ezibalulekileyo zinokutsalwa nge-steam distillation, i-hydro distillation, i-solvent extraction, ukucinezela, okanye i-effleurage (ukutsalwa kwamafutha).
I-chromatograph yegesi (GC) yindlela yokuhlalutya imichiza esetyenziselwa ukuchonga amaqhezu aguquguqukayo (amacandelo ngamnye) ngaphakathi kweoli ethile ebalulekileyo. Amacandelo ngamanye abhaliswa ngamaxesha ahlukeneyo kunye nezantya, kodwa alichongi igama elichanekileyo.2
Ukumisela oku, i-mass spectrometry (MS) idityaniswe ne-chromatograph yegesi. Le ndlela yokuhlalutya ichonga icandelo ngalinye ngaphakathi kweoyile, ukwenza iprofayile eqhelekileyo. Oku kunceda abaphandi banqume ukucoceka, ukuhambelana kwemveliso kunye nekhathalogu yeyiphi amacandelo anokuba nemiphumo yonyango.1,2,7
Kwiminyaka yakutshanje, i-gas chromatography-mass spectrometry (GC / MS) ibe yenye yeendlela ezidumileyo kunye nezisemgangathweni zokuvavanya i-oyile ebalulekileyo.1,2 Olu hlobo lokuvavanya luvumela abaphandi besayensi, ababoneleli, abavelisi kunye namashishini ukuba banqume ioli efunekayo. ubunyulu kunye nomgangatho. Iziphumo zihlala zithelekiswa nesampulu ethembekileyo ukumisela umgangatho ophakamileyo, okanye utshintsho ukusuka kwibhetshi ukuya kwibhetshi.
Ipapashe iziphumo zoVavanyo lweOyile ebalulekileyo
Okwangoku, abavelisi beoyile ebalulekileyo kunye nabathengisi abafunwa ukuba babonelele ngolwazi lovavanyo lwebhetshi kubathengi. Nangona kunjalo, iinkampani ezikhethiweyo zipapasha iziphumo zovavanyo lwebhetshi ukukhuthaza ukungafihli.
Ngokungafaniyo nezinye iimveliso zokuthambisa, ii-oyile ezibalulekileyo zisekelwe kwisityalo kuphela. Oku kuthetha ukuba ngokuxhomekeke kwixesha lonyaka, indawo yokuvuna kunye neentlobo zemifuno, iikhompawundi ezisebenzayo (kunye neenzuzo zonyango) zinokutshintsha. Olu tshintsho lubonelela ngesizathu esilungileyo sokuqhuba uvavanyo lwebhetshi rhoqo ukuqinisekisa umgangatho wemveliso kunye nokuhambelana.
Kwiminyaka yakutshanje, abathengisi abaninzi benze uvavanyo lwabo lwebhetshi lufumaneke kwi-Intanethi. Abasebenzisi banokufaka ibhetshi eyodwa okanye inombolo yeqashiso kwi-intanethi ukufumana ingxelo yeGC/MS ehambelana nemveliso yabo. Ukuba abasebenzisi bafumana nayiphi na imiba ngeoyile yabo ebalulekileyo, inkonzo yabathengi iya kuba nakho ukuchonga imveliso ngaba bamakishi.
Ukuba zikhona, iingxelo zeGC/MS zinokufumaneka ngokubanzi kwiwebhusayithi yomthengisi. Zihlala zihlala phantsi kweoli enye ebalulekileyo kwaye ziya kubonelela ngomhla wokuhlalutya, izimvo ezivela kwingxelo, zibandakanya ngaphakathi kweoli kunye nengxelo ephezulu. Ukuba iingxelo azifumaneki kwi-intanethi, abasebenzisi banokubuza kumthengisi ukuba bafumane ikopi.
IBanga loNyango lweeOyile ezibalulekileyo
Njengoko imfuno yemveliso yendalo kunye ne-aromatherapy isanda, kuye kwangeniswa amagama amatsha ukuchaza umgangatho we-oyile ekucingelwa ukuba uyeyona ndlela yokuhlala inokhuphiswano kwindawo yentengiso. Kule migaqo, 'I-Oli yoNyango yeBanga eliBalulekileyo' idla ngokuboniswa kwiilebhile ze-oli enye okanye imixube entsonkothileyo. `IBanga loNyango` okanye `iBanga A` libhengeza ingqikelelo yenkqubo yomgangatho wenqanaba, kwaye ioli ekhethiweyo kuphela enokuthi ifaneleke kwezi zihloko.
Kubalulekile ukuqaphela ukuba nangona iinkampani ezininzi ezaziwayo zilandela okanye zihamba ngaphezulu nangaphaya kweZiqhelo eziLungileyo zokuVelisa (GMP), akukho mgangatho wolawulo okanye inkcazo yeBanga loNyango.
