Khoom noj khoom haus thickener yog ib qho tseem ceeb tshaj plaws excipients nyob rau hauv kev lag luam khoom noj khoom haus, uas feem ntau plays lub luag hauj lwm ntawm stabilizing zaub mov daim ntawv nyob rau hauv cov zaub mov ua, xws li tuav lub stability ntawm suspended slurry, stability ntawm lub degree ntawm smoothness, thiab stability ntawm lub emulsion system.

Tsis tas li ntawd, nws tuaj yeem txhim kho qhov kov ntawm cov zaub mov thiab kev ruaj ntseg ntawm cov xim, aroma, saj thiab kua hauv lub xeev ntawm cov khoom noj. Lub luag haujlwm tseem ceeb ntawm thickener hauv kev ua zaub mov feem ntau yog tshwm sim hauv cov hauv qab no.

Khoom noj khoom haus thickeners yog hydrophilic polymers. Soluble nyob rau hauv dej muaj ib tug zoo viscosity, kom lub cev muaj ib tug tuab zoo nkaus li. Thaum lub viscosity ntawm lub system nce, lub dispersed theem nyob rau hauv lub system tsis yooj yim rau aggregate thiab condense, yog li nws muaj peev xwm ua rau cov dispersed system ruaj khov. Feem ntau cov thickeners muaj kev ua haujlwm ntawm surfactant, tuaj yeem adsorbed rau ntawm qhov chaw ntawm lub sijhawm dispersed, kom nws muaj qee yam hydrophilicity thiab yooj yim rau disperse tusyees nyob rau hauv dej system.

Qee cov thickeners, xws li gelatin, AGAR thiab lwm yam kev daws teeb meem, yog cov kua dej khov hauv cov dej sov. Thaum qhov kub thiab txias, cov tshuaj molecules txuas nrog rau hauv lub network qauv, cov kuab tshuaj thiab lwm yam dispersing xov xwm yog tag nrho cov nyob rau hauv lub network qauv, thiab tag nrho cov tsim ib tug semi-khoom tsis muaj zog, uas yog, ib tug gel. Ntau yam khoom noj khoom haus yog ua kom siv cov yam ntxwv ntawm cov thickener, xws li khov, custard thiab lwm yam.

Feem ntau cov thickeners yog cov ntaub ntawv polymer, thiab nyob rau hauv tej yam kev mob, ntau yam dispersion media tuaj yeem nqus tau tib lub sijhawm kom sib sau thiab sib cais, thiaj li ua tiav lub hom phiaj ntawm purification lossis purification. Yog hais tias ib qho me me ntawm gelatin ntxiv rau cov kua txiv hmab txiv ntoo, cov kua txiv hmab txiv ntoo tuaj yeem tau txais.

Cov nyhuv hydrophilic ntawm thickener tuaj yeem txhim kho cov khoom zoo ntawm cov nqaij thiab cov hmoov nplej. Hauv cov khoom noj noodle, cov thickener tuaj yeem txhim kho cov dej nqus ntawm cov khob noom cookie, thiab cov thickener tuaj yeem ua kom cov dej nkag mus rau hauv cov protein molecules thiab cov hmoov txhuv nplej siab thaum lub khob noom cookie tau npaj, uas yog qhov zoo rau cov hmoov sib tov. Vim lub gel cov khoom ntawm thickener, viscoelasticity ntawm cov khoom hmoov yog txhim kho, qib ntawm starch αization yog nce, thiab nws tsis yooj yim rau hnub nyoog thiab qhuav.

Kev siv cov thickener tuaj yeem muab cov khoom noj muaj viscosity ntau dua, kom cov tshuaj supersaturated lossis cov kab ke tsis tshwm sim crystallization lossis crystallization kom ua tiav cov txiaj ntsig zoo. Piv txwv li, tswj cov xuab zeb rov qab tshwm sim ntawm cov khoom syrup thiab inhibit cov dej khov muaju hauv cov khoom noj ice cream.

Khoom noj khoom haus thickener tuaj yeem tsim cov yeeb yaj kiab tiv thaiv zoo heev ntawm cov khoom noj khoom haus, tiv thaiv cov zaub mov los ntawm oxygen thiab kab mob. Nws tuaj yeem tiv thaiv qhov tsis zoo los ntawm qhov chaw noo noo nqus ntawm cov khoom noj khov thiab cov khoom noj hmoov.

Lub thickener tuaj yeem ua foamed los tsim ib lub network qauv. Ncuav mog qab zib, bakers, ice cream thiab lwm yam kev siv algin, locust taum pos hniav, sodium alginate, gelatin li foaming agents, thickening agents tuaj yeem txhim kho tus nqi ntawm cov npuas dej thiab ua npuas ncauj stability, xws li npias ua npuas ncauj thiab lub raj mis phab ntsa "cov plaub hau" yog vim li cas rau kev siv cov thickening agents.

Lub hom phiaj ntawm kev siv locust taum cov pos hniav thiab algin gum nyob rau hauv cov hnyuv ntxwm yog ua kom cov khoom ua ib qho agglomeration, cov ntaub so ntswg qauv ruaj khov thiab lubricated tom qab homogenization, thiab cov dej tuav lub zog ntawm cov kua nplaum yog siv los tiv thaiv cov hnyuv ntxwm los ntawm kev poob phaus. Cov pos hniav Arabic tuaj yeem siv los ua cov ntawv khi rau cov ntsiav tshuaj thiab cov khoom siv granular, hauv cov khoom siv hmoov nplej, granulation ntawm cov txuj lom zaub mov thiab lwm yam kev siv.
