5. Kev txhim kho kev ntxhib los mos:
Hauv cov zaub mov ua tiav, HPMC pab txhim kho kev ntxhib los mos, muab lub qhov ncauj du, creamy. Qhov no yog tshwj xeeb tshaj yog pom nyob rau hauv cov khoom xws li ice cream, qhov twg nws pab tiv thaiv cov dej khov los ntawm crystallizing thiab txhim kho tag nrho cov kev paub.
6. Kev hloov roj:
Hauv cov zaub mov tsis muaj rog lossis tsis muaj rog, HPMC tuaj yeem siv los hloov cov rog ib nrab, tswj cov kev xav zoo nkauj thiab lub qhov ncauj thaum txo cov roj tag nrho.
7. Gluten-dawb ci:
HPMC feem ntau yog siv rau hauv gluten-dawb ci ci rau qee qhov ntawm cov qauv thiab cov khoom siv ntawm gluten, yog li kev txhim kho cov khoom zoo xws li khob cij thiab khoom qab zib.
Kev siv hydroxypropyl methylcellulose hauv cov khoom noj
1. Cov khoom ci:
HPMC yog siv rau hauv ntau yam khoom ci, nrog rau cov qhob cij, ncuav mog qab zib thiab pastries, los txhim kho kev ntxhib los mos, ua kom ntev txee lub neej thiab txhim khu kev ruaj ntseg.
2. Cov khoom siv mis nyuj:
Hauv kev siv cov khoom noj siv mis, HPMC yog siv los tsim cov ice cream, yogurt thiab custard los tswj viscosity, tiv thaiv crystallization thiab txhim kho qhov ncauj.
3. Sauces thiab condiments:
HPMC ua tus stabilizer hauv cov kua ntsw thiab hnav khaub ncaws, tiv thaiv theem kev sib cais thiab ua kom muaj kev ntxhib los mos thiab zoo ib yam.
4. Khoom qab zib:
Cov khoom ua yeeb yaj kiab ntawm HPMC muaj txiaj ntsig zoo hauv daim ntawv thov confectionery thiab tuaj yeem siv rau txheej thiab encapsulating cov khoom xyaw.
5. Cov khoom noj nqaij:
Hauv cov khoom noj nqaij xws li hnyuv ntxwm thiab patties, HPMC pab txhim kho cov dej tuav, kev ntxhib los mos thiab tag nrho cov khoom zoo.
