Kuv lub teb chaws cov tshuaj tsw qab thiab tsw kev lag luam yog kev lag luam-taw qhia thiab kev lag luam thoob ntiaj teb.Cov tuam txhab tshuaj tsw qab thiab cov tshuaj tsw qab yog tag nrho cov nyob hauv Suav teb, thiab ntau cov tshuaj tsw qab thiab cov tshuaj tsw qab hauv tsev kuj tau xa tawm ntau ntau.Tom qab ntau tshaj 20 xyoo ntawm txoj kev loj hlob, kuv lub teb chaws cov tsw thiab cov tshuaj tsw qab kev lag luam tau tso siab rau kev nruam kev thev naus laus zis, tsis tu ncua kev tsim khoom thiab kev ua haujlwm, thiab kev lag luam tau ua tiav kev loj hlob.
Kev lag luam tsw txawv ntawm cov tshuaj tsw qab txhua hnub thiab cov khoom noj khoom haus.Industrial flavors yog tus cwj pwm los ntawm cov ntxhiab tsw ntxhib, kub kub ua haujlwm thiab cov ntxhiab tsw ntev.Lawv tsuas yog siv rau hauv cov yas, roj hmab, tshuaj coatings thiab xim inks.Nws yog siv los npog cov ntxhiab tsw thiab ua kom cov tshuaj tsw qab kom ua tiav qhov muag zoo.
Kev lag luam tsw yog ib qho tseem ceeb raw khoom kev lag luam txhawb cov khoom flavoring.Perfume yog raw khoom rau blending flavors;flavour yog dav siv nyob rau hauv cov zaub mov, dej haus, cawv, luam yeeb, detergents, tshuaj pleev ib ce, tshuaj txhuam hniav, tshuaj, pub, textiles thiab tawv industries.Ntxiv rau cov tshuaj tsw qab, tus nqi ntawm cov ntsiab lus hauv cov khoom sib txawv tsuas yog 0.3-3%, tab sis nws ua lub luag haujlwm tseem ceeb hauv cov khoom zoo, yog li tsw yog hu ua "tus ntsuj plig" ntawm cov khoom qab zib.
Raws li kev coj noj coj ua ntawm kev tshawb fawb thiab thev naus laus zis tshiab, kev tshawb fawb tshawb fawb thiab kev kawm ua haujlwm ntawm kuv lub teb chaws cov tshuaj tsw qab thiab tsw kev lag luam tau ua tiav cov txiaj ntsig zoo.Coj thawj lub tsev kawm ntawv ntawm Shanghai Institute of Technology ua piv txwv, nws cov neeg ua haujlwm tshawb fawb thiab thev naus laus zis kev cob qhia thiab kev tshawb fawb thiab thev naus laus zis tau txais txiaj ntsig.Lub tsev kawm ntawv tau tsim cov txuj ci kev cob qhia txoj haujlwm ntawm "kev cob qhia qib siab siv cov txuj ci thev naus laus zis nrog lub siab tshiab thiab muaj peev xwm ua tau zoo, thiab cov kws ua haujlwm zoo tshaj plaws nrog rau kev pom thoob ntiaj teb", thiab tsim "kev pabcuam hauv cheeb tsam kev lag luam thiab kev loj hlob ntawm kev sib raug zoo, ua haujlwm hauv nroog niaj hnub, thiab pab cov lag luam me thiab nruab nrab hauv nroog thiab cov lag luam me thiab nruab nrab, raws li hauv Shanghai, ntsib Yangtze River Delta, tawg thoob plaws lub tebchaws, thiab ntsib kev xav tau ntawm kev sib raug zoo ".
Lub sijhawm khaws cov tshuaj tsw qab ntawm cov ntsiab lus feem ntau yog 3-15 lub hlis.Vim tias cov tshuaj tsw qab sib txawv muaj qhov sib txawv ntawm cov volatilization ceev ntawm cov khoom sib txawv, nyob ntawm seb hom thiab cov qauv ntawm cov tshuaj tsw qab, thiab cov cua ntws yog cov yeeb ncuab ntawm cov tshuaj tsw qab ntawm cov ntsiab lus thiab cov tshuaj tsw qab, cov khoom tiav yog qhwv thiab muab tso rau hauv ib lub thawv. .Kev kho kom zoo nkauj thiab cov ntawv nplaum rau ntawm qhov chaw ntawm cov khoom tiav tuaj yeem txo qhov volatilization ntawm cov tshuaj tsw qab thaum lub sij hawm cia, yog li ncua lub sij hawm tuav cov tshuaj tsw qab ntawm cov khoom.
Cov txheej txheem supercritical carbon dioxide extraction yog siv los rho tawm cov roj tsis hloov pauv ntawm frangipani uas tsim nyob rau hauv Nplog teb.Nyob rau tib lub sijhawm, roj chromatography-mass spectrometry thev naus laus zis yog siv los txheeb xyuas cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov roj tsis hloov pauv, uas muab lub hauv paus kev tshawb fawb rau kev txhim kho thiab kev siv ntawm frangipani.Los ntawm kev sim kev tshawb fawb, pab neeg tshawb fawb tshawb fawb tau txiav txim siab cov txheej txheem rau supercritical carbon dioxide kua extraction ntawm frangipani roj: extraction siab 25Mpa, extraction kub 45 ° C, sib cais kuv siab 12Mpa, thiab sib cais kuv kub 55 ° C.Raws li cov xwm txheej no, qhov nruab nrab cov txiaj ntsig ntawm cov extract yog 5.8927%, uas yog siab dua qhov txiaj ntsig ntawm qhov ntsuas qhov ntsuas ntawm qhov ntsuas ntawm 0.0916%.
Tuam Tshoj cov khoom qab zib thiab cov tshuaj tsw qab ua lag luam muaj peev xwm loj hlob thiab ua lag luam chaw.Cov tuam txhab nto moo thoob ntiaj teb thiab cov tshuaj tsw qab tau nqis peev thiab tsim cov chaw tsim khoom hauv Suav teb.Nrog lawv cov thawj lub koob npe nrov thoob ntiaj teb thiab cov txiaj ntsig thev naus laus zis, lawv tau nyob feem ntau ntawm cov khoom qab zib hauv tsev thiab cov tshuaj tsw qab nruab nrab-rau-siab-kawg kev lag luam.Nyob rau tib lub sij hawm, tom qab xyoo ntawm txoj kev loj hlob, domestic private-muaj tsw thiab tshuaj tsw qab tsim lag luam tau tshwm sim ib tug xov tooj ntawm kev lag luam-ua lag luam.Kev cia siab rau lawv txoj kev paub txog cov khoom qab zib hauv zos, cov khoom lag luam ruaj khov, cov khoom tsim nyog, thiab cov kev pabcuam kev xav, cov tuam txhab ntiag tug no tau maj mam yeej qhov kev lees paub ntawm cov neeg siv khoom nruab nrab mus rau qib siab, thiab lawv cov kev lag luam thiab kev paub txog cov khoom lag luam tau nce ib hnub. .
Kev kub siab ua haujlwm, muaj zog ntxhiab tsw qab, lub ntsej muag ntev ntev, thiab lwm yam. Siv rau hauv cov khoom siv yas, cov khoom siv roj hmab, cov khoom siv khau, hnab ntim khoom, khoom siv tes ua, textiles, ntim khoom, cua qhov hluav taws xob, chav tsev so, khoom siv hauv tsev, ntawv sau, automotive sab hauv qhov chaw, thiab lwm yam. Nws yog ib qho yooj yim heev los siv rau hauv cov txheej txheem ntawm kev tsim cov khoom yas, kom cov khoom yas muaj cov tshuaj tsw qab zoo tuav.
Kev tsim khoom thiab kev loj hlob ntawm kev lag luam tsw thiab tshuaj tsw qab yog sib xws nrog kev txhim kho kev txhawb nqa kev lag luam xws li kev lag luam, dej haus, thiab tshuaj txhua hnub.Cov kev hloov pauv sai hauv cov kev lag luam hauv qab no tau txhawb txoj kev loj hlob tsis tu ncua ntawm kev lag luam tsw thiab tshuaj tsw qab, nrog kev txhim kho cov khoom zoo, tsis tu ncua ntawm ntau yam, tso zis thiab muag.Ntau xyoo dhau los.Txhawm rau kom ntseeg tau tias qhov kev xav tau loj ntawm cov kev lag luam hauv qab thiab txhawb kev txhim kho ntawm cov neeg siv khoom lag luam, yuav ua li cas los txhawb kev hloov pauv thiab kev txhim kho kev lag luam tau dhau los ua ib qho teeb meem rau kev lag luam.
Ntxiv rau cov tuam txhab txawv teb chaws hauv Suav teb, cov tuam txhab lag luam hauv xeev muaj cov kev tshawb fawb tsis muaj zog, cov ntsiab lus tsis tshua muaj txiaj ntsig, kev tswj tsis tau yooj yim, thiab kev paub txog kev pabcuam tsis muaj zog, uas tau ua rau qeeb lossis txawm tias rov qab los ntawm lawv txoj kev loj hlob tam sim no.Nrog kev txhawb nqa ntawm cov kev cai hauv tebchaws tam sim no, lub nroog thiab cov tuam txhab ntiag tug tau tsim kho sai.Nrog lawv cov kev hloov pauv hloov pauv thiab cov kev pabcuam xav tau, lawv tau txais kev qhuas los ntawm cov neeg siv khoom, thiab lawv txoj kev lag luam tau nthuav dav tas li.Txawm li cas los xij, rau feem ntau cov lag luam ntiag tug, vim kev lag luam tsis zoo thiab kev siv thev naus laus zis, kev paub tsis zoo ntawm cov khoom lag luam, thiab cov khoom lag luam tsis ruaj khov, qhov xwm txheej no tau ua rau muaj kev sib koom ua ke ntawm kev lag luam thiab muab lub hauv paus rau cov thawj coj hauv kev lag luam kom loj thiab muaj zog.
