Kusiyana pakati pa HPMC ndi MHEC

HPMC (Hydroxypropyl Methylcellulose) ndi MHEC (Methylhydroxyethylcellulose) ndi mitundu iwiri ya zotumphukira za cellulose zomwe zimagwiritsidwa ntchito mosiyanasiyana. Zonsezi ndi zinthu zopangidwa ndi ma polima zomwe zimagwiritsidwa ntchito kukhuthala, kumanga, ndi kukhazikika kwazinthu. Onsewa amagwiritsidwa ntchito kwambiri m'mafakitale azakudya, azamankhwala, ndi zodzikongoletsera.

Kusiyana kwakukulu pakati pa HPMC ndi Mhec ndi mtundu wa cellulose womwe umagwiritsidwa ntchito kupanga. HPMC imapangidwa kuchokera ku hydroxypropyl methylcellulose, pomwe Mhec imapangidwa kuchokera ku methylhydroxyethylcellulose. HPMC ndi mtundu woyengedwa kwambiri wa cellulose, pomwe Mhec ndi mawonekedwe osayengedwa kwambiri.

HPMC ndi ufa woyera, wopanda fungo, komanso wopanda kukoma womwe umasungunuka m'madzi ozizira. Amagwiritsidwa ntchito ngati thickening wothandizira, emulsifier, stabilizer, ndi kuyimitsa wothandizira pazinthu zosiyanasiyana. Amagwiritsidwanso ntchito kuonjezera mamasukidwe akayendedwe a mayankho komanso kukonza kapangidwe ka zinthu. Nthawi zambiri amagwiritsidwa ntchito pazakudya monga ayisikilimu, sauces, ndi zovala.

Kumbali ina, Mhec ndi ufa woyera, wopanda fungo, ndi wosakoma umene umasungunuka m’madzi otentha ndi ozizira. Amagwiritsidwa ntchito ngati thickening wothandizira, emulsifier, stabilizer, ndi kuyimitsa wothandizira pazinthu zosiyanasiyana. Amagwiritsidwanso ntchito kuonjezera mamasukidwe akayendedwe a mayankho komanso kukonza kapangidwe ka zinthu. Nthawi zambiri amagwiritsidwa ntchito pazakudya monga ayisikilimu, sauces, ndi zovala.

Pankhani ya magwiridwe antchito, HPMC nthawi zambiri imadziwika kuti ndiyothandiza kwambiri kuposa Mhec. Ndizokhazikika komanso zimakhala ndi viscosity yapamwamba kuposa Mhec. Imalimbananso kwambiri ndi kusintha kwa kutentha ndi pH. Kuphatikiza apo, HPMC imakhala ndi nthawi yayitali kuposa Mhec.

Pankhani ya mtengo, HPMC nthawi zambiri imakhala yokwera mtengo kuposa Mhec. Izi zili choncho chifukwa HPMC ndi mtundu woyengedwa kwambiri wa cellulose motero ndi wokwera mtengo kupanga.

Ponseponse, HPMC ndi Mhec onse amagwiritsidwa ntchito kwambiri m'mafakitale azakudya, azamankhwala, ndi zodzikongoletsera. Onsewa amagwiritsidwa ntchito ngati thickening agents, emulsifiers, stabilizers, ndi suspending agents muzinthu zosiyanasiyana. HPMC nthawi zambiri imadziwika kuti ndiyothandiza kwambiri kuposa Mhec, koma ndiyokwera mtengo.
