HPMC VS HEC: 6 Kusiyana Zomwe Muyenera Kudziwa!

Tsegulani:

Hydroxypropylmethylcellulose (HPMC) ndi hydroxyethylcellulose (HEC) onse amagwiritsidwa ntchito kwambiri m'mafakitale azakudya, zodzikongoletsera ndi zamankhwala. Zotuluka pa cellulosezi zimakhala ndi mwayi wogwiritsa ntchito kwambiri chifukwa cha kusungunuka kwawo kwapadera kwamadzi, kukhazikika kwa kukhuthala, komanso luso lapamwamba lopanga mafilimu.

1.Mapangidwe a Chemical:

HPMC ndi polima opangidwa kuchokera ku mapadi. Amapangidwa ndikusintha ma cellulose achilengedwe powonjezera propylene oxide ndi methyl chloride. HEC imakhalanso mtundu wa cellulose yochokera ku cellulose, koma imapangidwa ndikuchitapo kanthu pa cellulose yachilengedwe ndi ethylene oxide kenako ndikuchiza ndi alkali.

2. Kusungunuka:

Onse HPMC ndi HEC ndi madzi sungunuka ndipo akhoza kusungunuka m'madzi ozizira. Koma kusungunuka kwa HEC ndikotsika kuposa HPMC. Izi zikutanthauza kuti HPMC ili ndi dispersibility yabwinoko ndipo ingagwiritsidwe ntchito mosavuta popanga.

3. Makanema:

HPMC ndi HEC ali ndi makhalidwe osiyana mamasukidwe akayendedwe chifukwa cha mankhwala awo. HEC ili ndi kulemera kwakukulu kwa maselo ndi kapangidwe kake kocheperako kuposa HPMC, zomwe zimapatsa kukhuthala kwakukulu. Choncho, HEC nthawi zambiri amagwiritsidwa ntchito ngati thickener mu formulations amafuna mkulu mamasukidwe akayendedwe, pamene HPMC ntchito formulations amafuna kutsika mamasukidwe akayendedwe.

4. Kupanga mafilimu:

Onse HPMC ndi HEC ali ndi luso lopanga mafilimu. Koma HPMC ili ndi kutentha kwapang'onopang'ono kupanga mafilimu, kutanthauza kuti ikhoza kugwiritsidwa ntchito pa kutentha kochepa. Izi zimapangitsa HPMC kukhala yoyenera kugwiritsidwa ntchito popanga zomwe zimafunikira nthawi yowuma mwachangu komanso kumamatira bwino.

5. Kukhazikika:

HPMC ndi HEC ndizokhazikika pansi pa pH zambiri ndi kutentha. Komabe, HEC imakhudzidwa kwambiri ndi kusintha kwa pH kuposa HPMC. Izi zikutanthauza kuti HEC iyenera kugwiritsidwa ntchito popanga ma pH 5 mpaka 10, pamene HPMC ingagwiritsidwe ntchito mu pH yowonjezereka.

6. Kugwiritsa ntchito:

Makhalidwe osiyanasiyana a HPMC ndi HEC amawapangitsa kukhala oyenera ntchito zosiyanasiyana. HEC imagwiritsidwa ntchito ngati thickening agent muzodzoladzola ndi mankhwala. Amagwiritsidwanso ntchito ngati chomangira komanso chopangira filimu pamapangidwe a piritsi. HPMC ntchito monga thickener, stabilizer, ndi filimu kupanga wothandizila chakudya, mankhwala, ndi zodzikongoletsera formulations. Amagwiritsidwanso ntchito ngati gelling wothandizira pazakudya zina.

Pomaliza:

HPMC ndi HEC onse ndi zotuluka pa cellulose zomwe zili ndi zinthu zapadera zomwe zimayenera kugwiritsidwa ntchito mosiyanasiyana. Kumvetsetsa kusiyana pakati pa zowonjezera ziwirizi kungakuthandizeni kusankha yoyenera pa maphikidwe anu. Ponseponse, HPMC ndi HEC ndizowonjezera zotetezeka komanso zothandiza zomwe zimapereka zabwino zambiri kumakampani azakudya, zodzikongoletsera ndi zamankhwala.
