Citric Acid Anhydrous yog dab tsi?
Citric acid yog cov organic acid uas tuaj hauv ob hom: Anhydrous thiab Monohydrate. Feem ntau, citric acid tshwm sim tsis muaj dej, uas yog vim li cas nws thiaj li hu ua Citric Acid Anhydrous.
Citric Acid Anhydrous (CAS 77-92-9) yog ib qho tseem ceeb organic acid acid. Nws zoo li cov hmoov dawb crystalline hmoov thiab muaj lub zog qaub saj, ua rau nws nrov heev raws li cov khoom noj ntxiv. Dhau li ntawm kev lag luam zaub mov, nws kuj tau siv dav hauv kev lag luam tshuaj thiab tshuaj lom neeg.
Cov yam ntxwv ntawm Citric Acid Anhydrous
Cov tshuaj formula rau Citric Acid Anhydrous yog C₆H₈O₇. Nws yaj yooj yim heev hauv dej thiab ethanol, uas tso cai rau nws sib tov sai rau ntau hom kua mis.
Nws yog ib qho tsim nyog sau cia tias 1% dej daws ntawm Citric Acid Anhydrous muaj pH txog 2.2. Qhov no acidity muaj zog ua rau nws ua tau zoo pH adjuster thiab chelating tus neeg saib xyuas.
Saib ntawm nws cov qauv, Citric Acid Anhydrous tsis muaj cov dej siv lead ua. Qhov no muab nws ntau dua concentration thiab stability piv rau Citric Acid Monohydrate. Hauv qhov chaw qhuav, nws yuav tsis poob dej zoo li daim ntawv monohydrate ua. Txawm li cas los xij, nyob rau hauv huab cua ntub, Citric Acid Anhydrous tuaj yeem nqus dej me ntsis, yog li koj yuav tsum tau them sai sai rau ntim thiab khaws cia.
Sinoright tau muab cov khoom citric acid tsis tu ncua rau ntau tus neeg siv khoom hauv ntau lub tebchaws rau kaum xyoo dhau los. Peb pom qhov kev thov siab rau siab - zoo Citric Acid Anhydrous. Raws li peb cov kev paub dhau los, siab- zoo Citric Acid Anhydrous feem ntau yuav tsum muaj qhov purity ntawm 99.5%-101% thiab khaws cov hlau hnyav qis dua 10ppm. Tsuas yog los ntawm kev ua raws li cov qauv no tuaj yeem ua kom cov khoom zoo thiab tsim nyog rau kev siv high-end.
Qhov sib txawv ntawm Monohydrate thiab Citric Acid Anhydrous
Qhov sib txawv loj tshaj plaws ntawm Citric Acid Monohydrate thiab Citric Acid Anhydrous yog seb lawv puas muaj cov dej molecules. Monohydrate feem ntau muaj li ntawm 7.5% -9.0% siv lead ua dej, thaum Anhydrous muaj yuav luag tsis muaj dej (dej cov ntsiab lus<0.5%). This difference alone leads to very different uses.

Hauv kev tsim khoom tiag tiag, xaiv qhov tsis ncaj ncees lawm hom citric acid tuaj yeem muaj qhov tshwm sim loj thiab ua rau poob. Piv txwv li, ib lub tuam txhab dej haus European ib zaug siv Monohydrate los ntawm kev ua yuam kev hauv cov dej haus hmoov. Qhov no ua rau cov khoom nqus dej noo thiab clump ua ke, ua rau poob ntau dua 2 lab Euros.
Cov kws tshaj lij xws li Sinoright cov kws tshaj lij pab pawg qhia tias koj xav txog peb yam tseem ceeb: cov dej ua dej num, ua haujlwm kub, thiab lub sijhawm cia. Yog tias xav tau, koj tuaj yeem thov cov qauv dawb los kuaj kev sib raug zoo.
Cov txheej txheem ntau lawm thiab kev tswj kom zoo
Txoj kev tsim khoom
Muaj peb txoj hauv kev ua kom citric acid: txiv hmab txiv ntoo extraction, tshuaj synthesis, thiab lom fermentation. Tam sim no, fermentation yog txoj kev tseem ceeb. Cov pwm hu ua Aspergillus niger tuaj yeem ferment cov khoom xyaw uas muaj cov hmoov txhuv nplej siab los tsim cov citric acid. Yog li ntawd, txhua yam khoom siv raw nrog cov hmoov txhuv nplej siab tuaj yeem siv tau.
Niaj hnub nimno Citric Acid Anhydrous ntau lawm tsuas yog siv "submerged fermentation." Nws siv Aspergillus niger los ferment cov ntaub ntawv carbohydrate. Cov txheej txheem ib txwm muaj xws li:
- Kab lis kev cai theem: Cov pwm yog zus nyob rau hauv ib tug sib tov ntawm wort thiab agar ntawm 31℃rau 4 hnub los tsim ib tug siab - tawm los strain.
- Fermentation txheej txheem: Fermentation tshwm sim nyob rau hauv ib puag ncig acidic (pH 1.5-2.8) nrog cua thiab sib tov rau 5-7 hnub. Lub tank kub yog nruj me ntsis khaws cia nyob ib ncig ntawm 35 degree.
- Extraction thiab Purification: Cov kua fermented neutralized nrog calcium carbonate ua calcium citrate. Tom qab ntawd, nws raug kho nrog sulfuric acid kom tau cov kua qaub kua qaub. Cov impurities raug tshem tawm siv ion txauv resins.
- Crystallization thiab ziab: Cov khoom yog crystallized ntawm qhov kub siab tshaj 78 degree. Tom qab ntawd nws tau qhuav rau hauv ib lub txaj fluidized kom tau cov muaju tsis muaj dej thiab ua rau ntau qhov sib txawv (8-100 mesh).
Kev Tswj Xyuas Zoo
Kev tswj kom zoo yuav tsum tshwm sim thoob plaws hauv tag nrho cov txheej txheem tsim khoom. Raws li tus neeg xa khoom nrog ntau tshaj kaum xyoo ntawm kev xa tawm, Sinoright's Citric Acid Anhydrous cov khoom tau lees paub los ntawm ISO 9001, Halal, thiab KOSHER. Peb xyuas kom txhua pawg los nrog cov ncauj lus kom ntxaws COA (Certificate of Analysis) kom tau raws li EU REACH cov cai thiab US FDA GRAS cov cai.
Kev siv ntawm Citric Acid Anhydrous
Lub versatility ntawm Citric Acid Anhydrous ua rau nws tseem ceeb hauv ntau qhov kev lag luam.
- Kev Lag Luam Khoom Noj: Nws yog siv los ua cov kua qaub (E330) hauv cov dej qab zib, jelly, thiab khoom qab zib. Cov lus pom zoo yog 0.1% -0.5%. Nws muab cov qaub saj tshiab thiab boosts cov nyhuv ntawm antioxidants, ncua lub neej txee los ntawm 30%.
- Tshuaj: Cov kev cai purity ntawm no yog nruj heev. Hauv cov ntsiav tshuaj effervescent, nws hnov mob nrog sodium bicarbonate los pab cov ntsiav tshuaj tawg sai sai (solving hauv qab 3 feeb). Nws kuj tseem siv los ua cov tshuaj tiv thaiv coagulant hauv cov kua dej lim ntshav.
- Kev Siv Khoom Siv: Nws lub peev xwm los khi cov hlau (chelation) ua rau nws tseem ceeb rau eco- cov neeg huv huv. Hauv kev kho hlau, nws tshem tawm cov txheej txheem xeb tsis ua rau lub hauv paus hlau. Hauv kev kho dej, ntxiv 1-2g / L tuaj yeem txo qis calcium thiab magnesium.
Qhov tseem ceeb, raws li EU txwv phosphate-raws li cov tshuaj ntxuav tes, kev siv Citric Acid Anhydrous hauv cov qauv ntxuav ntsuab tau loj hlob los ntawm 12% txhua xyoo.
Cia thiab tuav
Cia
Kev khaws cia kom raug yog qhov tseem ceeb rau kev ua tau zoo. Raws li Sinoright's Material Safety Data Sheet (MSDS), kev cia khoom yuav tsum:
- Kub ntawm 15-25 degree, txheeb ze humidity Tsawg dua los yog sib npaug li 60%.
- Cov hnab ntawv lined nrog PE lossis ntawv ci hnab (25kg txhua). Siv hauv 24 teev tom qab qhib.
- Cov chaw khaws cia yuav tsum tau nchuav pallets thiab cov av noo saib xyuas.
- Khaws tsawg kawg 3 meters deb ntawm cov muaj zog oxidizers thiab alkalis.
tuav
Handling requires training. When pouring or mixing, wear dust masks and nitrile gloves to avoid breathing in dust or touching the skin. Without protection, citric acid dust levels can get too high (>5mg / m³), uas tuaj yeem ua rau cov hlab ntsws ua pa lossis ua rau mob hawb pob. Rau kev txav mus los loj, siv cov tshuab thiab xyuas kom muaj huab cua zoo hauv cheeb tsam.
Raws li cov xwm txheej no, lub txee lub neej yog 36 lub hlis. Txawm li cas los xij, ib txwm siv txoj cai "First-In, First-Tawm" txoj cai. Tshawb xyuas cov khoom txhua peb lub hlis rau kev ya raws; yog tias clumping tshaj 5%, xav siv nws rau qis dua - qib hom phiaj.
Cov ntsiab lus tseem ceeb rau kev yuav khoom ntau
Thaum muas Citric Acid Anhydrous hauv ntau, tus nqi tseem ceeb, tab sis tsis yog tus qauv nkaus xwb. Tus nqi qis heev feem ntau txhais tau tias qis purity los yog tsis zoo hnyav hlau tswj.
Cov neeg yuav khoom yuav tsum siv cov ntsuas no los txiav txim rau cov neeg muag khoom:
- Daim ntawv pov thawj: ISO 9001, FSSC 22000, Kosher / Halal.
- Technical Ability: Fermentation conversion rate (>95% yog qhov zoo), batch stability (purity hloov tsawg dua los yog sib npaug li 0.3%).
- Supply Chain: Yam tsawg kawg nkaus Order Quantity (MOQ), lub sij hawm xa tuaj (feem ntau 30 hnub, ceev 7 hnub).
- Cov Kev Pabcuam Ntxiv: Cov qauv dawb (feem ntau yog 500g), qhov loj me me (30-100 mesh), tech txhawb teb (hauv 24 teev).
- Cov Lus Cog Tseg: Qhia meej meej tias yuav tsum muaj COA rau txhua pawg, txhais cov cai rov qab rau cov teeb meem hlau hnyav, thiab muaj kev npaj rau cov khoom tsis txaus. Cov neeg siv khoom tshiab yuav tsum sim me me rau 3 lub hlis los kuaj cov khoom ua ntej yuav ntau dua.
Sinoright muaj ntau tshaj 10 xyoo ntawm kev xa tawm. Lawv qhov zoo dua yog muab txhua yam los ntawm kev sim me me (1kg) mus rau ntau lawm (20 tons / thawv). Cov khoom yog BRC thiab FDA tau ntawv pov thawj, thiab lawv txhawb ntau yam kev lag luam xws li FOB thiab CIF. Lawv qhov kev soj ntsuam zoo tuaj yeem taug qab cov khoom los ntawm cov khoom siv raw mus rau cov khoom kawg.
Xaus
Citric Acid Anhydrous yog ib qho tseem ceeb ntawm cov khoom noj, tshuaj, thiab kev tu vim nws cov kua qaub zoo heev thiab ntxuav cov khoom. Cov tuam txhab lag luam yuav tsum xaiv cov khoom lag luam uas ua tau raws li cov qauv thoob ntiaj teb kom paub meej purity thiab kev nyab xeeb.
Tsim kom muaj kev koom tes ntev - kev koom tes nrog ib tus neeg muab ntawv pov thawj zoo li Sinoright ua kom muaj cov khoom siv ruaj khov. Nws kuj tseem muab rau koj nkag mus rau kev txhawb nqa kev cai thiab kev ua lag luam hloov tshiab, pab koj txuag nyiaj thiab txo cov kev pheej hmoo.
