Txais tos rau kev lag luam wholesale mag zoo zoo ntshiab ntshiab vanillin CAS 121-33-5 rau muag ntawm no los ntawm peb lub hoobkas. Cov kev pabcuam zoo thiab tus nqi tsim nyog muaj.
Ntshiab vanillin, tseem hu ua vanillin, lub npe hu ua tshuaj yog 3-metoxy-4-hydroxy-4-hydroxy-4-hydroxybenzaldehyde. Nws yog ib hom organic muab rho tawm los ntawm vanilla taum ntawm lub rooj mov Rutaceae. Nws yog dawb rau daj daj crystalline lossis crystalline hmoov, qab zib me ntsis, soluble hauv dej kub, glycubin thiab dej cawv, thiab insoluble hauv dej txias thiab zaub roj. Lub aroma yog ruaj khov thiab tsis txhob tawm tsam ntawm qhov kub. Nws yog qhov yooj yim rau oxidize hauv huab cua thiab discolor thaum alkaline tshuaj.
Nws muaj aroma taum thiab muaj zog mis nyuj aroma, thiab yog dav siv hauv tshuaj pleev ib ce, thiab yog cov khoom qab zib, khoom qab zib, khoom noj khoom haus thiab lwm yam khoom lag luam. Nws yog ib qho ntawm cov hluavtaws loj tshaj plaws hauv ntiaj teb. Kev lag luam tsim muaj keeb kwm ntau tshaj 100 xyoo. Cov zaub mov pom zoo nyob rau hauv cov zaub mov kawg flavored yog li 0.2- 20000 mg / kg. Raws li cov kev cai ntawm Minisation ntawm kev noj qab haus huv ntawm Suav, Vanillin tuaj yeem siv rau cov menyuam yaus thiab cov menyuam yaus uas muaj 5mg / ml thiab 7mg / 100g feem. Nws kuj tseem tuaj yeem siv los ua tsob ntoo loj hlob txhawb nqa, fungicide, lubricating roj defoamer, thiab lwm yam kuj yog ib qho kev sib txuam tseem ceeb ntawm cov khoom siv hluavtaws thiab lwm cov txuj lom. Ib qho ntxiv, nws kuj tseem tuaj yeem siv los ua tus neeg sawv cev sib sau ua ke hauv kev ua liaj ua teb, raws li tus neeg saib xyuas roj hmab hauv kev ua liaj ua teb, raws li cov neeg sawv cev ua haujlwm hauv cov khoom siv yas, thiab raws li cov khoom siv hluav taws xob. Nws yog siv dav.

Cov khoom noj khoom noj khoom haus tau muab faib ua cov khoom noj kom zoo thiab lwm cov txheej txheem los tswj cov khoom noj khoom haus cov khoom noj kom zoo nkauj, txhim kho cov nqi khoom noj kom zoo, txhim kho lub sijhawm zoo. Piv nrog cov tshuaj tiv thaiv tshuaj, ntuj txhawb nqa tau qhov zoo rau ib puag ncig, cov nqi tsim txom qis, cov nyhuv khaws cia zoo.Ntshiab vanillinHauv cov zaub mov tuaj yeem raug kuaj pom yog los ntawm UV - pa tawm suab, chromatography, electropraphy, electrophoresis thiab lwm txoj hauv kev. Nws yog cov khoom noj nyab xeeb. Daim ntawv thov hauv cov zaub mov cia thiab kev khaws cia tuaj yeem faib ua cov kab mob kis, ua rau muaj lwm yam khoom xyaw ua pa.
Nws yog cov neeg sawv cev ntawm lub ntuj, uas feem ntau ua ke nrog lwm cov kev sib tw hauv cov zaub mov, thiab muaj cov kev cuam tshuam sib txawv ntawm cov sib txawv. Cov nyhuv bacteriostatic muaj feem xyuam rau nws cov kev xav thiab tus nqi PH. Kev xav tau siab dua thiab tus nqi ntawm tus nqi qis dua txhawm rau txhim kho cov nyhuv bacteriostatic. Cov nyhuv bacteriostatic ntawm cov sib txawv sib txawv yog qhov sib txawv. Piv nrog rau lwm cov leeg, cov nyhuv bacteriostatic ntawm Escherichia Coli yog qhov zoo dua. Nws muaj cov kev cuam tshuam ntawm ntau yam poov xab. Kev siab siab tuaj yeem txhim kho nws cov nyhuv ntawm cov tshuaj tua kab mob, tab sis qhov siab siab tsis tuaj yeem tua cov poov xab tam sim ntawd. Compound Fresh- Ua kom pom cov synergy ntawm tshiab {}} Cov tswv yim lees paub rau cov txiv hmab txiv ntoo thiab zaub. Cov nyhuv tua kab mob cov txuj lom feem ntau muaj syergy thiab ntau npaum li cas yog me dua li ntawm ib leeg siv. Piv txwv li, rau kev tiv thaiv aspergillus niger muaj kuab paug, cov tshuaj vanillin zoo ib leeg yog 0.5% vanillin thiab 0.0025% cinnamaldehyde tuaj yeem ua si bacnericidal lub luag haujlwm.
Nws kuj tseem yog lub luag haujlwm tseem ceeb hauv cov kab mob bacteriostasis thiab kom tsis muaj menyuam. Nyob rau hauv cov txheej txheem ntau lawm, thermal tsis muaj menyuam yog tseem cov kev tsis sib xws tshaj plaws hauv kev ua kua txiv hmab txiv ntoo kua txiv thiab siab}}} intantaneous tsis muaj menyuam. Cov kev ua kom tsis muaj menyuam yaus feem ntau ua rau kev rhuav tshem cov khoom noj muaj kua txiv thiab cov khoom siv browning.
Qhov kev txiav txim mechanism ntawm Antioxidants nrog cov qauv zoo sib txawv yog txawv. Nws tsuas yog nrawm nrawm ntawm kev tshem tawm ntawm dawb radicals los ntawm oxidation khoom vanilic acid. Nws cov nyhuv antioxidant tuaj yeem ua kom ntev ntev ntev lub txee lub neej ntawm oily cov zaub mov thiab npog nws rancidity. Lub isomer, o - me vanillin (3-methoxy-2-hydroxy-2-hydroxy-2-Hydroxy-2-Hydroxy-2-Hydroxy-2-Hydroxy-2-Hydroxy-2-Hydroxitrite Aion, tab sis nws tsis yog qhov dawb radical scavenger.
Nws tau raug pov thawj tias cov tshuaj tiv thaiv khoom ntawmntshiab vanillinMuaj peev xwm pab ua rau lwm cov khoom xyaw hauv cov khoom noj: resveratrol yog lub ntuj muaj kev ua haujlwm zoo nkauj. Txhawm rau txhim kho nws qhov ruaj khov thiab muab tag nrho lub luag haujlwm, cov tshuaj tiv thaiv chitosan tom qab cov tshuaj tiv thaiv thiab chitosan tau siv los tswj cov kev tso tawm ntawm resveratrol; Lub hws cov khoom lag luam thiab cov amino pab pawg muaj lub peev xwm zoo ntawm cov hlau ions, thiab tuaj yeem txhim kho qhov ruaj khov ntawm nws cov cuab yeej muaj.
Cov hau hluav taws xob
Vanillin, tseem hu ua Vanillyl aldehyde lossis 3 {{} methoxy-4-hydroxy-4-hydrotefenzalhyde, yog cov tshuaj tsw qab nrog cov ntxhiab tsw qab-zoo li tsw. Nws yog dav siv nyob rau hauv cov zaub mov, naj hoom, thiab kws tshuaj lag luam vim nws qab ntxiag aroma. Cov synthesis cuam tshuam ntau txoj kev, uas tuaj yeem yog categorized rau hauv tshuaj synthesis thiab enzymatic synthesis. Hauv qab no yog cov lus qhia ntxaws ntxaws rau qee cov tshuaj synthesis:
Tshuaj Synthesis Cov Qauv
- Pib Kauj Ruam: N,N-dimethylaniline is acidified with hydrochloric acid to form its salt, which is then nitrated with sodium nitrite to obtain p-nitrosodimethylaniline hydrochloride.
- Lwg: Cov nruab nrab no yog ces condensed nrog gaugiacol thiab formaldehyde ntawm qhov ntsuas kub ntawm 41-43 degree.
- Extract thiab purification: Benzene siv rau extraction, ua raws los ntawm distillation thiab recrystallization nrog benzene thiab dej feem. Kom qhuav ntawm 50℃yields cov khoom kawg.
- Tau qhov twg los cov khoom: Lignin sulfonates muaj hydroxybenenzyl cawv cov txheej txheem, muab tau los ntawm sulfite pulp khib nyiab, yog siv.
- Oxidation Thiab Hydrolysis: Nyob rau hauv Alkaline cov xwm txheej, lub hnub ci sulfonates yog oxidized thiab tom qab hydrolyzed los tsim cov vanillin.
- Reactant: 2-methoxyphenol, sodium g dlyoxylate, thiab sodium hydroxide muaj sib xyaw hauv dej.
- Cov xwm txheej tiv thaiv: Cov sib tov tau ua kom nruj thiab khaws cia ntawm 25℃rau 24 teev nrog ib qho kev piv me me (2-methoxyfate: sodium hydroxide: Dej}: 24: 13: 950).
Enzymatic synthesis txoj kev
Nyob rau hauv xyoo tas los, Seczymatic synthesis tau tawm los ntawm kev xaiv kev xaiv vim nws cov kev ua phooj ywg ib puag ncig thiab kev xav tau.
Enzyme koom tes
Nws synthease yog ib qho enzyme uas catalyzes lub synthesis los ntawm kev tshwj xeeb substrates.
Kev npaj
Lub enzyme yog huv thiab muab rho tawm nyob rau hauv cov xwm txheej tsim nyog. Nws mam li catalyzes hloov dua siab tshiab ntawm kev nthuav dav rau hauv vanillin nyob rau hauv muaj cofactors.
Ntshiab vanillin, tseem hu ua 4 {- hydroxy-3-methoxybenhdehyde, yog ib txwm muaj nyob hauv vanilla taum, cov txiv hmab txiv ntoo vanilla orchid. Nws yog lub luag haujlwm rau qhov sib txawv, qab zib, thiab cream aroma thiab tsw txuam nrog vanilla. Commercially, it is widely used as a flavoring agent in foods, beverages, pharmaceuticals, and cosmetics. Nws tseem ua haujlwm hauv qhov kev lag luam ntxhiab vim nws cov ntxhiab tsw qab. Thaum ib txwm muaj vanillin yog muab rho tawm los ntawm vanilla taum, uas tuaj yeem tsim cov tshuaj vanillin, cov khoom siv hluav taws xob ua haujlwm los ntawm cov khoom siv tshuaj lom neeg, ua rau nws muaj ntau dua rau ntau yam kev siv. Ob daim ntawv zoo nkauj thiab cov hluavtaws tau raug lees paub rau lawv lub peev xwm los txhim kho cov saj thiab tsw qab cov khoom lag luam.
