1. Gelatin Txhais & Cov Tshuaj Lom Zem

Gelatin(kuj tseem hu uacollagen noj taulos yogisinglass) yog ib qho polymer polypeptide ntuj uas tau los ntawm kev hydrolysis ib feem ntawm collagen uas tau rho tawm los ntawm cov nqaij sib txuas ntawm cov tsiaj, suav nrog daim tawv nqaij, pob txha, thiab cov leeg ntawm npua, nyuj, thiab ntses. Chemically, gelatin muaj 18 amino acids, nrog rauglycine(≈33%),alanine,proline, thiabhydroxyproline(ua ke ≈33%) ua cov khoom tseem ceeb. Nws kuj muaj cov kab kawm thiab ua kom pom cov khoom amphoteric vim nws cov amino acid profile, ua rau nws muaj txiaj ntsig zoo thoob plaws cov khoom noj, tshuaj, thiab kev lag luam.

2. Cov Khoom Siv Lub Cev thiab Tshuaj Lom Zem ntawm Gelatin

Gelatin zoo li hmoov tsis muaj xim mus rau daj ntseg, daim ntawv, lossis cov khoom me me uas muaj cov qauv ci ntsa iab, tsis muaj ntxhiab, thiab tsis muaj saj (qhov ceev: 1.3–1.4 g/cm³). Cov yam ntxwv tseem ceeb suav nrog:

  1. Kev yaj tauTsis yaj hauv dej txias, ethanol, lossis chloroform tab sis yaj hauv dej kub, glycerol, thiab acetic acid.

  2. Muaj Peev Xwm Haus DejNqus tau 5–10 npaug ntawm nws qhov hnyav hauv dej, ua rau nws ua gel thaum txias (35–40°C).

  3. Kev rhiab heev ntawm cua sovKev npau ntev ntev ua rau nws cov qauv puas tsuaj, ua rau lub peev xwm gelling puas tsuaj.

  4. Lub zog ntawm gelKev tsim cov gel zoo tshaj plaws tshwm sim ntawm 10–15% concentration, cuam tshuam los ntawm pH, ntsev, thiab kub.

Cov khoom no ua lub luag haujlwm ua tus neeg sawv cev gelling, stabilizer, thiab emulsifier hauv ntau yam lag luam.

3. Cov Txheej Txheem Tsim Gelatin: Cov Txheej Txheem Acid, Alkaline, thiab Enzymatic

Kev tsim cov gelatin suav nrog kev rho tawm collagen los ntawm cov khoom siv raw los ntawm tsiaj los ntawm peb txoj kev tseem ceeb:

3.1 Cov Txheej Txheem Rho Tawm Acid

  • Txheej TxheemCov khoom siv raw (piv txwv li, daim tawv npua) raug kho nrog cov kua qaub (HCl, citric acid) kom cuam tshuam cov collagen crosslinks, ua raws li kev rho tawm ntau theem (60 ° C, 80 ° C, 90 ° C).

  • Cov txiaj ntsigLub voj voog tsim khoom luv luv (3–7 hnub).

  • Cov kev txwvKev pheej hmoo ntawm kev xeb ntawm cov khoom siv siab; qhov siab dua ntawm isoelectric point (pH 7–9) txwv tsis pub siv.

  • Siv: Cov khoom noj gelatin rau cov khoom qab zib thiab cov khoom noj mis nyuj.

3.2 Txoj Kev Alkaline (Txiv qaub ntsuab)

  • Txheej TxheemCov khoom siv raw: Cov khoom siv raw raug tsau rau hauv dej limewater (20 ° C, 20 lub lis piam) rau kev hydrolysis maj mam thiab tshem tawm cov khoom tsis huv.

  • Cov txiaj ntsig: Cov gelatin uas huv heev nrog cov nitrogen tsawg (<18%) thiab qhov chaw isoelectric zoo tagnrho (pH 4.7–5.2).

  • Kev tswj hwm: Muaj li ntawm 80% ntawm Tuam Tshoj cov gelatin tsim tawm, nyiam siv rau kev thaij duab thiab tshuaj.

  • Cov Kev Sib Tw: Lub sijhawm ua haujlwm ntev, cov dej khib nyiab ntau.

3.3 Kev Siv Tshuab Enzymatic Hydrolysis

  • Txheej Txheem: Collagen raug kho ua ntej nrog cov proteases kom ua kom cov hydrolysis sai dua (5-10 hnub), txo cov kev cuam tshuam rau ib puag ncig.

  • Cov txiaj ntsig: Zoo rau ib puag ncig, txuag hluav taws xob, thiab tuaj yeem ua haujlwm tau raws li kev siv tshuab.

  • Cov teeb meemTus nqi enzyme siab, kev ruaj khov qis, thiab kev cov nyom hauv kev tsim khoom loj.

4. Kev Ua Tom Qab Tsim Khoom

Cov kauj ruam tom qab rho tawm ua kom muaj txiaj ntsig zoo rau kev lag luam:

  1. Kev ntxuav kom huvKev siv: Hydrogen peroxide bleaching thiab filtration.

  2. Kev NtsuasKev Ua Kom Qhuav: Ua kom qhuav ntawm 35°C mus txog 40% cov khoom khov.

  3. Kev ziab thiab ua kom zoo nkaujKev Khov, Txiav, thiab ziab kom txog thaum muaj dej noo li ntawm 10–12%.

5. Kev Siv Gelatin Hauv Kev Lag Luam

  1. Kev Lag Luam Khoom Noj: Tus neeg sawv cev gelling hauv cov khoom qab zib, yogurt, thiab whipped cream.

  2. Cov TshuajCov plhaub tshuaj ntsiav, cov ntaub qhwv qhov txhab, thiab cov txheej txheem xa tshuaj.

  3. Tshuaj pleev ib ce: Cov khoom ua kom tuab hauv cov cream thiab serums.

  4. Kev thaij duab: Cov txheej txheem rhiab heev rau lub teeb hauv cov yeeb yaj kiab archival.

  5. Kev siv tshuab biotechnologyCov khoom siv rau kev cog qoob loo ntawm tes thiab cov matrices luam tawm 3D bioprinting.

Xaus lus

Raws li cov khoom lag luam collagen uas muaj ntau yam, gelatin cov yam ntxwv ua haujlwm tshwj xeeb thiab biocompatibility ua rau nws tsis tseem ceeb thoob plaws cov sectors. Thaum cov txheej txheem ib txwm muaj (acid / alkaline) tswj hwm, kev nce qib hauvKev siv tshuab enzymatic hydrolysiscog lus tias yuav tsim khoom kom ruaj khov thiab ua tau zoo. Txij li kev ua zaub mov molecular mus rau kev tsim kho biomedical, gelatin txuas ntxiv hloov zuj zus ua cov khoom siv biomultifunctional tseem ceeb.

Cov Lus Tseem Ceeb: gelatin, collagen noj tau, ntses gelatin (isinglas), collagen hydrolysis, cov txheej txheem tsim gelatin

Cov Lus Tseem Ceeb Thib Ob: gelatin uas tau ua los ntawm kua qaub, gelatin txoj kev ua los ntawm txiv qaub ntsuab, enzymatic hydrolysis, kev siv gelatin, cov khoom ntawm gelatin
