Qhov txawv ntawm gelatin thiab collagen yog dab tsi?
- Kev Txhais thiab Cov Qauv
Gelatin yog ib qho protein uas tau los ntawm kev hydrolysis ib feem ntawm collagen, ib qho protein fibrous uas muaj ntau nyob rau hauv cov nqaij sib txuas ntawm cov tsiaj xws li daim tawv nqaij, pob txha, thiab cov leeg. Collagen muaj cov qauv triple-helix uas ruaj khov los ntawm cov hydrogen bonds, ua rau nws muaj zog tensile siab. Qhov sib piv, gelatin cov qauv yog ib lub kauj random denatured vim yog qhov tawg ntawm collagen cov helical bonds thaum lub sijhawm ua, uas tso cai rau nws yaj hauv dej kub thiab tsim cov gels thaum txias.
- Cov txheej txheem rho tawm
Collagen Kev rho tawm yuav tsum muaj cov txheej txheem maj mam los khaws nws cov qauv ib txwm muaj, feem ntau siv cov enzymes lossis kev kho mob acid / alkaline me me ntawm qhov kub qis. Txawm li cas los xij, kev tsim cov gelatin yuav tsum muaj kev hydrolysis ntau dua: cov khoom siv raw raug rhaub lossis kho nrog cov kua qaub / alkalis muaj zog kom tawg collagen cov peptide bonds. Qhov sib txawv ntawm kev ua tiav no piav qhia vim li cas collagen khaws nws cov qauv kev ncaj ncees, thaum gelatin tau txais cov khoom gelling.
- Cov ntawv thov
Collagen muaj nqis heev rau cov tshuaj ntxiv rau kev txhawb nqa kev noj qab haus huv ntawm cov pob qij txha thiab daim tawv nqaij elasticity, vim nws cov qauv molecular muaj sia nyob hauv kev zom zaub mov zoo dua. Gelatin qhov kev hloov pauv ci ntsa iab cov khoom noj khoom haus(jellies, marshmallows), tshuaj (capsules), thiab tshuaj pleev ib ce (creams), qhov twg nws cov peev xwm gelling, thickening, thiab zaj duab xis-tsim yog qhov tseem ceeb heev. Tsis zoo li collagen, gelatin tus qauv denatured ua rau nws yooj yim dua los koom ua ke rau hauv ntau yam formulations.
