Cov tsw qab ntuj puas zoo dua li cov tsw qab dag

Los ntawm qhov pom ntawm kev lag luam, cov tshuaj tsw qab yog siv los kho cov saj ntawm cov tshuaj tsw qab volatile, nws qhov chaw tau muab faib ua ob pawg: ib qho yog "ntuj tsw qab", los ntawm cov nroj tsuag, tsiaj txhu, cov khoom siv microbial siv "txoj kev lub cev" rho tawm cov tshuaj tsw qab; Ib qho yog "tshuaj tsw qab hluavtaws", uas yog ua los ntawm qee qhov "distillate" thiab acid, alkali, ntsev thiab lwm yam tshuaj tau los ntawm cov khoom siv hauv av xws li roj av thiab thee los ntawm kev kho tshuaj thiab kev ua tiav. Nyob rau hauv xyoo tas los no, cov tsw qab ntuj tau raug nrhiav tom qab heev thiab tus nqi tau nce siab, tab sis cov tsw qab ntuj puas zoo dua li cov tsw qab hluavtaws?

Cov txuj lom ntuj tsim muaj plaub hom: musk, civet, castoreum thiab ambergris; Cov tshuaj tsw qab ntuj tsim yog cov organic sib xyaw uas rho tawm los ntawm cov paj, nplooj, ceg, qia, txiv hmab txiv ntoo, thiab lwm yam, ntawm cov nroj tsuag tsw qab. Cov txuj lom hluavtaws muaj cov txuj lom semi-synthetic thiab cov txuj lom hluavtaws tag nrho: kev siv cov khoom ntuj tsim tom qab tshuaj lom neeg los hloov cov qauv ntawm cov txuj lom hu ua cov txuj lom semi-synthetic, kev siv cov khoom siv tshuaj lom neeg yooj yim hu ua cov txuj lom hluavtaws tag nrho. Raws li kev faib tawm ntawm cov pab pawg ua haujlwm, cov tshuaj tsw qab hluavtaws tuaj yeem faib ua ether tshuaj tsw qab (diphenyl ether, anisole, thiab lwm yam), aldehyde-ketone tshuaj tsw qab (musketone, cyclopentadecanone, thiab lwm yam), lactone tshuaj tsw qab (isoamyl acetate, amyl butyrate, thiab lwm yam), cawv tshuaj tsw qab (cawv rog, cawv tsw qab, cawv terpenoid, thiab lwm yam), thiab lwm yam.

Cov tsw qab thaum ntxov tsuas yog siv cov tsw qab ntuj tsim los ua xwb, tom qab muaj cov tsw qab tsim los, cov kws ua tshuaj tsw qab yuav luag txhua lub sijhawm los npaj ntau yam tsw qab kom tau raws li qhov xav tau ntawm txhua tus neeg hauv lub neej. Rau cov neeg ua haujlwm hauv kev lag luam thiab cov neeg siv khoom, qhov kev txhawj xeeb tseem ceeb yog kev ruaj khov thiab kev nyab xeeb ntawm cov txuj lom. Cov tsw qab ntuj tsis tas yuav muaj kev nyab xeeb, thiab cov tsw qab tsim los tsis tas yuav muaj kev nyab xeeb. Kev ruaj khov ntawm cov tsw qab feem ntau pom tseeb hauv ob qho: thawj zaug, lawv qhov ruaj khov hauv aroma lossis saj; Qhov thib ob, kev ruaj khov ntawm cov khoom siv lub cev thiab tshuaj hauv nws tus kheej lossis hauv cov khoom; Kev nyab xeeb hais txog seb puas muaj kev lom hauv qhov ncauj, kev lom ntawm daim tawv nqaij, kev khaus rau daim tawv nqaij thiab qhov muag, seb puas yuav ua xua rau daim tawv nqaij, seb puas muaj kev lom ntawm photosensitivity thiab daim tawv nqaij photosensitization.

Hais txog cov txuj lom, cov txuj lom ntuj yog cov khoom sib xyaw ua ke, cuam tshuam los ntawm cov yam xws li keeb kwm thiab huab cua, uas tsis yooj yim ruaj khov hauv cov khoom sib xyaw thiab aroma, thiab feem ntau muaj ntau yam sib xyaw. Cov khoom sib xyaw ntawm aroma yog qhov nyuaj heev, thiab nrog rau qib tam sim no ntawm chemistry thiab biotechnology, nws nyuaj rau ua tiav kev tshuaj xyuas kom raug thiab nkag siab txog nws cov khoom aroma, thiab qhov cuam tshuam rau tib neeg lub cev tsis yooj yim to taub. Qee qhov kev pheej hmoo no peb tsis paub; Cov khoom sib xyaw ntawm cov txuj lom hluavtaws yog qhov tseeb, kev sim tshuaj lom neeg tseem ceeb tuaj yeem ua tiav, kev siv muaj kev nyab xeeb tuaj yeem ua tiav, thiab aroma ruaj khov, thiab aroma ntawm cov khoom ntxiv kuj tuaj yeem ruaj khov, uas coj peb yooj yim rau kev siv.

Raws li cov kuab tshuaj seem, cov tshuaj tsw qab tsim los ntawm cov khoom siv zoo ib yam li cov tshuaj tsw qab ntuj. Cov tsw qab ntuj kuj xav tau cov kuab tshuaj hauv cov txheej txheem rho tawm. Hauv cov txheej txheem ntawm kev tsim cov kuab tshuaj, cov kuab tshuaj tuaj yeem tswj tau hauv qhov ntau yam kev nyab xeeb los ntawm kev xaiv cov kuab tshuaj thiab kev tshem tawm.

Feem ntau cov tsw qab ntuj thiab cov tsw qab kim dua li cov tsw qab tsim los ntawm cov tshuaj, tab sis qhov no tsis muaj feem cuam tshuam ncaj qha rau kev nyab xeeb, thiab qee cov tsw qab tsim los ntawm cov tshuaj kuj kim dua li cov tsw qab ntuj. Tib neeg xav tias cov tshuaj zoo dua, qee zaum vim tias cov tsw qab ntuj ua rau tib neeg qab ntxiag dua, thiab qee cov khoom xyaw me me hauv cov tsw qab ntuj yuav ua rau muaj qhov sib txawv me ntsis rau qhov kev paub. Tsis yog cov tshuaj zoo, cov tshuaj tsis zoo, tsuav yog siv raws li cov cai thiab cov qauv muaj kev nyab xeeb, thiab hais txog kev tshawb fawb, cov txuj lom tsim los ntawm cov tshuaj tuaj yeem tswj tau, muaj kev nyab xeeb dua, tam sim no, tsim nyog dua rau pej xeem siv.
