Qhov sib txawv tseem ceeb ntawm gelatin thiab pectin yog tias gelatin yog sib xyaw ntawm peptides thiab cov proteins, qhov pectin yog polysaccharide.
Ob lub gelatin thiab pectin yog cov khoom sib xyaw ua ke. Cov tebchaw no tshwm sim dav hauv cov kabmob muaj sia; Yog li, nws yog ib qho tseem ceeb heev uas yuav tsum tau kawm lawv cov khoom thiab qhov xwm txheej. Tsis tas li ntawd, ob lub tebchaw no yog cov tshuaj ua kom tuab siv feem ntau los ua cov khoom noj xws li jam thiab jelly.
Gelatin yog dab tsi?
Gelatin yog sib xyaw ntawm peptides thiab cov proteins muab los ntawm cov ntaub so ntswg tsiaj. Nws yog translucent, tsis muaj xim thiab flavourless. Peb tuaj yeem muab tau los ntawm collagen uas tau muab los ntawm cov ntaub so ntswg tsiaj. Yog li ntawd, lub ntsiab lus ntawm gelatin yog hydrolyzed collagen. Txawm li cas los xij, qhov no hydrolysis yog irreversible. Thaum lub sij hawm no hydrolysis txheej txheem, cov protein fibrils hauv collagen hloov mus rau hauv me me peptides. Qhov hnyav molecular ntawm cov me me peptides poob rau hauv ntau yam.
Daim duab 01: Qhuav Gelatin
Thaum moist, gelatin yog cov kua nplaum (peb tuaj yeem txhais tau tias "gummy"), thiab thaum qhuav, nws yog nkig. Feem ntau, peb siv cov tshuaj no ua cov tshuaj gelling rau cov zaub mov, tshuaj, cov tshuaj vitamin capsules, thiab lwm yam. Cov tshuaj uas muaj gelatin yog "gelatinous tshuaj". Thaum xav txog cov amino acid cov ntsiab lus ntawm gelatin, nws zoo ib yam li collagen, thiab nws muaj feem ntau 19 amino acids xws li glycine, proline thiab hydroxyproline. Peb cov amino acids no tsim txog li 50% ntawm cov khoom.
Pectin yog dab tsi?
Pectin yog cov qauv polysaccharide uas muaj nyob hauv cov phab ntsa ntawm tes thiab hauv qee hom algae. Txawm hais tias nws tshwm sim lawm, peb tuaj yeem tsim nws ua cov hmoov dawb rau lub teeb xim av. Peb tuaj yeem tshem pectin los ntawm citrus txiv hmab txiv ntoo. Daim ntawv thov loj ntawm cov khoom siv no yog nyob rau hauv kev lag luam zaub mov ua tus neeg sawv cev gelling rau jams. Pectin yog nplua nuj nyob rau hauv galacturonic acid.
Daim duab 02: Qhov tshwm sim ntawm Pectin
Cov khoom siv rau cov khoom siv no suav nrog pears, guava, kua, txiv kab ntxwv, gooseberries, thiab lwm yam. Txawm li cas los xij, cov txiv hmab txiv ntoo mos xws li cherries kuj muaj me me ntawm pectin.
Qhov txawv ntawm Gelatin thiab Pectin yog dab tsi?
Gelatin yog sib xyaw ntawm peptides thiab cov proteins uas tau los ntawm cov ntaub so ntswg tsiaj thaum pectin yog cov qauv polysaccharide uas muaj nyob hauv cov phab ntsa ntawm cov nroj tsuag thiab hauv qee hom algae. Yog li peb tuaj yeem hais tias qhov sib txawv tseem ceeb ntawm gelatin thiab pectin yog gelatin yog sib xyaw ntawm peptides thiab cov proteins thaum pectin yog polysaccharide. Ntxiv mus, thaum moist, gelatin yog cov kua nplaum heev, thiab thaum qhuav, nws yog ib daim ntawv uas tsis muaj xim. Pectin, ntawm qhov tod tes, tshwm sim raws li cov hmoov dawb rau lub teeb xim av. Lwm qhov sib txawv ntawm gelatin thiab pectin yog pectin yog cov nroj tsuag keeb kwm thaum gelatin tsis yog neeg tsis noj nqaij.
Summary – Gelatin vs Pectin
Ob leeg gelatin thiab pectin yog gelling agents. Qhov sib txawv tseem ceeb ntawm gelatin thiab pectin yog gelatin yog sib xyaw ntawm peptides thiab cov proteins, qhov pectin yog polysaccharide. Thaum siv los ua khoom noj khoom haus, nws yog ib qho tseem ceeb kom paub tias pectin yog cov nroj tsuag keeb kwm thaum gelatin yog tsiaj (tsis yog neeg tsis noj nqaij).
