Gelatin rau khoom qab zib thiab khoom qab zib

Gelatin: "Industrial MSG" - Cov Khoom Siv Biopolymer Ntau Yam

Gelatin yog ib yam khoom tau los ntawm ib nrab hydrolysis ntawm collagen. Nws yog ib tug natural siab -molecular- hnyav protein colloid nrog zoo heev gelling muaj peev xwm, stability, zaj duab xis- tsim cov khoom, thiab biocompatibility. Tsis muaj xim, tsis muaj ntxhiab, thiab pob tshab, gelatin yog dav siv hauv cov khoom noj, tshuaj, tshuaj pleev ib ce, thiab kev lag luam, ua rau nws yog ib qho tseem ceeb "tag nrho - rounder" raw khoom nyob rau hauv niaj hnub kev lag luam.Appearance: Colorless mus rau lub teeb daj pob tshab nplooj ntawv los yog hmoov; tsw thiab tasteless

Solubility: Insoluble hauv dej txias, tab sis tuaj yeem nqus tau 5-10 npaug ntawm nws qhov hnyav hauv dej kom o thiab muag muag; soluble nyob rau hauv dej kub ntawm 60-80℃los tsim ib tug colloidal tov, uas solidifies rau hauv ib lub gel thaum txias.

Gelling zog: Thermoreversible - liquefies thaum rhuab thiab gels thaum txias; gel lub zog yog ntsuas los ntawm Bloom tus nqi (0-400 g), nrog rau cov nqi siab dua qhia tias muaj zog gels

Stability: ruaj khov nyob rau hauv pH ntau ntawm 3-7; nquag degradation nyob rau hauv ib puag ncig alkaline; Cov cua sov ntev ntawm qhov kub siab tuaj yeem ua rau cov qauv colloidal puas

1. Kev Lag Luam Khoom Noj (≈70% ntawm tag nrho cov kev thov)

① Gelling tus neeg saib xyuas (daim ntawv thov tseem ceeb)

jelly, pudding, gummies: Ntxiv qib 0.5% -2%; cov ntaub ntawv pob tshab, elastic gel qauv nrog chewy tseem yaj-hauv-- qhov ncauj kev ntxhib los mos

Cov khoom noj nqaij: nqaij npua, hnyuv ntxwm, cov kaus poom nqaij (2% -9%); txhim kho cov dej tuav, txhim kho elasticity, thiab ncua lub neej txee

Mousses thiab cream qab zib: 0.3% -1%; muab cov qauv ua npuas ruaj khov thiab ua kom lub ntsej muag du, muag muag

② Stabilizer thiab thickener

Cov khoom noj mis: yogurt thiab ice cream (0.1% -0.5%); tiv thaiv whey sib cais thiab txhim kho kev ntxhib los mos

Haus dej kom meej meej: Npias thiab kua txiv hmab txiv ntoo (0.01% -0.05%); khi nrog tannins los tsim flocculates, txhim kho clarity

2. Pharmaceutical Field (High-kev siv kawg)

Capsule shells (kev siv thawj zaug):

Cov tshuaj ntsiav nyuaj (200-300 Bloom) thiab mos capsules (150-200 Bloom), kom ntseeg tau sai sai hauv plab

Hnav khaub ncaws phais thiab hemostatic sponges: Zoo heev biocompatibility, txhawb qhov txhab kho

Sustained -tso tawm formulations: Tswj cov tshuaj tso tawm tus nqi thiab prolongs kho cov teebmeem

Cov ntaub so ntswg engineering scaffolds: Muab peb - qauv qauv rau kev loj hlob ntawm tes; siv rau hauv kev txiav- ntug teb xws li cov nqaij kab lis kev cai

3. Kev saib xyuas tus kheej thiab kev siv ua lag luam

Tshuaj pleev ib ce:

Creams thiab lotions (0.5% -2%) kom viscosity thiab stability; ntsej muag daim npog qhov ncauj cov ntaub ntawv muab ib tug firming nyhuv

Kev yees duab: Txheej rau cov ntaub ntawv photosensitive, ua kom muaj kev sib txawv ntawm cov nyiaj halide crystals

Industrial adhesives: Sandpaper thiab sib tsoo log manufacturing, woodworking, printing inks

Lwm tus: Electroplating additives, match manufacturing, txheej rau suab paj nruag cov hlua
