Lub ntsiab sib txawv ntawm natural thickeners thiab hluavtaws thickeners nyob rau hauv lawv cov peev txheej thiab cov qauv tshuaj.
Qhov chaw
Natural thickeners: feem ntau yog muab los ntawm polysaccharides muab rho tawm los ntawm cov nroj tsuag, seaweed, los yog kab mob. Piv txwv li, cov pos hniav arabic, carrageenan, pectin, carrageenan, alginate, tamarind gum, chitin, guar gum, locust taum gum, thiab xanthan gum. Lwm qhov yog cov khoom uas tau muab rho tawm los ntawm cov tsiaj cov ntaub ntawv raw uas muaj cov protein, xws li gelatin, casein, chitosan, thiab lwm yam.
Synthetic thickener: ua los ntawm cov tshuaj synthesis lossis semi synthesis txoj kev. Hom thickener no suav nrog sodium carboxymethyl cellulose, propylene glycol alginate, thiab ntau yam hloov pauv starches xws li sodium carboxymethyl starch, hydroxypropyl starch ether, sodium starch phosphate, thiab lwm yam.
Chemical Structure
Natural thickeners: feem ntau yog qhov hnyav molecular polysaccharides lossis cov proteins uas tuaj yeem tsim cov qauv hauv network lossis muaj ntau pawg hydrophilic hauv dej, yog li ua kom cov viscosity ntawm cov tshuaj.
Synthetic thickeners: Lawv tej zaum yuav muaj molecular hnyav hluavtaws polymers xws li sodium polyacrylate, polyvinyl cawv, polyacrylamide, thiab lwm yam. Cov hluavtaws thickeners muaj cov qauv tshuaj tshwj xeeb thiab tuaj yeem tsim cov qauv hauv dej, yog li ua kom cov viscosity ntawm cov tshuaj.
Daim ntawv thov nta
Natural thickeners: Ntxiv nrog rau lawv cov nyhuv thickening, qee qhov ntuj thickeners kuj muaj lwm yam dej num, xws li tso cov aroma zoo thaum lub sij hawm gelation, uas yog haum rau cov txiv hmab txiv ntoo flavored zaub mov.
Synthetic thickeners: feem ntau muaj viscosity siab dua thiab ruaj khov zoo dua, haum rau cov khoom noj uas yuav tsum tau khaws cia ntev.
Kev nyab xeeb thiab kev cai
Natural thickeners feem ntau suav hais tias yog cov khoom noj muaj txiaj ntsig zoo vim tias lawv tau muab los ntawm cov tshuaj hauv qhov xwm txheej.
Synthetic thickeners: Txawm hais tias nruj me ntsis ntsuas rau kev nyab xeeb khoom noj, lawv yuav ua rau muaj kev txhawj xeeb txog lawv cov kev noj qab haus huv cuam tshuam rau qee qhov xwm txheej. Cov cai tswj kev nyab xeeb ntawm cov khoom noj ntawm ntau lub teb chaws yuav nruj me ntsis tswj cov nqi siv thiab cov khoom siv hluavtaws.
Hauv cov ntsiab lus, natural thickeners thiab hluavtaws thickeners sib txawv hauv lawv qhov chaw, cov qauv tshuaj, cov yam ntxwv ntawm daim ntawv thov, thiab kev nyab xeeb. Qhov kev xaiv ntawm cov thickener nyob ntawm cov kev xav tau ntawm kev ua zaub mov tshwj xeeb thiab kev xav txog kev nyab xeeb ntawm zaub mov.
