Gelation yog txoj kev dav dav los hloov cov kua dej mus rau ib qho khoomthiab tau siv txij thaum ancient sij hawm los tsim ntau yam khoom noj uas txawv textures. Cov khoom noj xws li gelatin-raws li cov khoom qab zib yog qee cov khoom noj yooj yim, muaj cov dej-gelatin gel nrog ntxiv qab zib, tsw thiab xim.
txheej txheem gelation yog dab tsi?
Gelation tuaj yeem txhais tau tias kev tsim ntawm peb-dimensional network los ntawm tshuaj lom neeg lossis lub cev sib txuas… ib tug system ntawm infinite viscosity, i.e. ib gel. Ib lub gel yuav raug suav hais tias yog ib qho elastic heev, zoo li roj hmab.
piv txwv ntawm gelation yog dab tsi?
Piv txwv ntawm cov nyiaj tsis muaj zog ntawm lub cev yog cov ntawv cog lus hydrogen, thaiv copolymer micelles, thiab cov koom haum ionic. Ntawm qhov tod tes, tshuaj gelation cuam tshuam nrog tsim covalent bonds thiab ib txwm ua rau muaj zog gel. Peb cov txheej txheem tshuaj gelation tseem ceeb suav nrog condensation, vulcanisation, thiab ntxiv polymerisation
txheej txheem gelation tshwm sim li cas?
1.10.
Gelation phenomena tshwm sim thaum tsawg viscosity SLNs dispersion hloov dua siab tshiab rau hauv viscous gel Cov txheej txheem tsim gel yog sai thiab tsis tuaj yeem kwv yees. Cov txheej txheem yog irreversible thiab feem ntau cuam tshuam qhov poob ntawm colloidal particle loj. … Cov txheej txheem ntawm crystallization tau tshaj tawm rau kev tsim cov gel.
gelation hauv protein yog dab tsi?
Kinsella [1] txhais cov gelation raws li hydration, structural, textural, thiab rheological khoom ntawm cov proteins. Schmidt [4] txhais gelation raws li protein aggregation tshwm sim nyob rau hauv uas polymer-polymer thiab polymer-solvent kev sib cuam tshuam yog li sib npaug uas lub tertiary network lossis matrix yog tsim
