Kusiyana pakati pa HPS ndi HPMC
Wowuma wa Hydroxypropyl(HPS) ndiHydroxypropyl methyl cellulose(HPMC) ndi ma polysaccharides awiri omwe amagwiritsidwa ntchito kwambiri pamafakitale osiyanasiyana, kuphatikiza mankhwala, chakudya, ndi zomangamanga. Ngakhale kufanana kwawo, HPS ndi HPMC ali ndi kusiyana kosiyana m'thupi ndi mankhwala, komanso ntchito zawo. M'nkhaniyi, tiwona kusiyana pakati pa HPS ndi HPMC malinga ndi kapangidwe kake ka mankhwala, katundu, ndi ntchito.
Kapangidwe ka Chemical
HPS ndi chochokera ku wowuma chomwe chimapezeka posintha mankhwala owuma achilengedwe ndi magulu a hydroxypropyl. Magulu a hydroxypropyl amamangiriridwa kumagulu a hydroxyl pa molekyulu ya wowuma, zomwe zimapangitsa kuti wowuma wosinthidwa wokhala ndi kusungunuka komanso kukhazikika. HPMC, kumbali ina, ndi yochokera ku cellulose yomwe imapezeka posintha ma cellulose ndi magulu a hydroxypropyl ndi methyl. Magulu a hydroxypropyl amalumikizidwa ndi magulu a hydroxyl pa molekyulu ya cellulose, pomwe magulu a methyl amamangiriridwa kumagulu a anhydroglucose.
Katundu
HPS ndi HPMC ali ndi mawonekedwe apadera a thupi ndi mankhwala omwe amawapangitsa kukhala oyenera kugwiritsidwa ntchito mosiyanasiyana. Makhalidwe a HPS ndi awa:
- Kusungunuka: HPS imasungunuka m'madzi ndipo imatha kupanga mayankho omveka bwino pamlingo wochepa.
- Viscosity: HPS ili ndi mamasukidwe otsika poyerekeza ndi HPMC ndi ma polysaccharides ena.
- Kukhazikika: HPS imakhala yokhazikika pamitundu yosiyanasiyana ya kutentha ndi pH milingo ndipo imalimbana ndi ma enzyme ndi zinthu zina zowononga.
- Gelation: HPS imatha kupanga ma gels osinthika a thermally pazambiri, zomwe zimapangitsa kuti zikhale zoyenera pazakudya ndi mankhwala osiyanasiyana.
Makhalidwe a HPMC ndi awa:
- Kusungunuka: HPMC imasungunuka m'madzi ndipo imapanga mayankho omveka bwino pamlingo wochepa.
- Viscosity: HPMC imakhala ndi kukhuthala kwakukulu ndipo imatha kupanga mayankho owoneka bwino ngakhale pazambiri zochepa.
- Kukhazikika: HPMC imakhala yokhazikika pamitundu yosiyanasiyana ya kutentha ndi pH milingo ndipo imalimbana ndi ma enzyme ndi zinthu zina zowononga.
- Kutha kupanga mafilimu: HPMC imatha kupanga makanema owonda, osinthika omwe ali othandiza pazamankhwala ndi zodzikongoletsera zosiyanasiyana.
Mapulogalamu
HPS ndi HPMC ali ndi ntchito zosiyanasiyana chifukwa cha katundu wawo wosiyana. Ntchito za HPS zikuphatikiza:
- Chakudya: HPS imagwiritsidwa ntchito ngati kunenepa ndi kukhazikika m'zakudya zosiyanasiyana, monga sosi, soups, ndi mavalidwe.
- Mankhwala: HPS imagwiritsidwa ntchito ngati chomangira komanso chosokoneza m'mapiritsi ndi makapisozi komanso ngati galimoto yoperekera mankhwala.
- Ntchito yomanga: HPS imagwiritsidwa ntchito ngati chokhuthala komanso chomangira zinthu zopangidwa ndi simenti, monga matope ndi konkire.
Ntchito za HPMC zikuphatikiza:
- Chakudya: HPMC imagwiritsidwa ntchito ngati thickener ndi stabilizer mu zakudya zosiyanasiyana, monga ayisikilimu, yoghurt, ndi zophika.
- Mankhwala: HPMC imagwiritsidwa ntchito ngati binder, disintegrant, and film-forming agent mu mapiritsi ndi makapisozi komanso ngati galimoto yoperekera mankhwala.
- Chisamaliro Chawekha: HPMC imagwiritsidwa ntchito muzinthu zosiyanasiyana zodzisamalira, monga mafuta odzola, ma shampoos, ndi zodzoladzola, monga chowonjezera komanso chokhazikika.
- Zomangamanga: HPMC imagwiritsidwa ntchito ngati chokhuthala komanso chomangira zinthu zopangidwa ndi simenti, monga matope ndi konkriti, komanso ngati zokutira zomangira.
Mapeto
Pomaliza, HPS ndi HPMC ndi ma polysaccharides awiri omwe amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana. HPS ndi chochokera ku wowuma chomwe chimakhala ndi kukhuthala kocheperako, chimasinthidwa ndi kutentha, ndipo chimakhala chokhazikika pakutentha kosiyanasiyana ndi pH. HPMC, kumbali ina, ndi yochokera ku cellulose yomwe imakhala ndi viscosity yayikulu, imatha kupanga mafilimu opyapyala, osinthika, komanso imakhala yokhazikika pakutentha kosiyanasiyana ndi pH. Kusiyanitsa pakati pa mankhwala awiriwa kumapangitsa kuti akhale oyenera kugwiritsidwa ntchito mosiyanasiyana m'mafakitale osiyanasiyana, kuphatikizapo chakudya, mankhwala, chisamaliro chaumwini, ndi zomangamanga.
Pankhani ya kapangidwe kake ka mankhwala, HPS ndi wowuma wosinthidwa womwe uli ndi magulu a hydroxypropyl, pomwe HPMC ndi cellulose yosinthidwa yomwe ili ndi magulu onse a hydroxypropyl ndi methyl. Kusiyanitsa kumeneku kumapangidwe a mankhwala kumathandizira kuti pakhale mawonekedwe apadera a thupi ndi mankhwala a mankhwalawa, monga kusungunuka, kukhuthala, kukhazikika, ndi gelation kapena kupanga mafilimu.
Ntchito za HPS ndi HPMC ndizosiyananso chifukwa cha mawonekedwe awo apadera. HPS imagwiritsidwa ntchito nthawi zambiri ngati chokhuthala komanso chokhazikika muzakudya, chomangira ndi chophatikizira muzamankhwala, komanso chokhuthala ndi chomangira pazomangira. Pakalipano, HPMC imagwiritsidwa ntchito kwambiri ngati thickener ndi stabilizer mu zakudya zakudya, binder, disintegrant, ndi filimu kupanga wothandizila mankhwala, thickener ndi stabilizer mu mankhwala chisamaliro munthu, ndi thickener, binder, ndi ❖ kuyanika wothandizila mu zomangamanga.
Mwachidule, HPS ndi HPMC ndi ma polysaccharides awiri omwe amagwiritsidwa ntchito nthawi zambiri omwe ali ndi mawonekedwe apadera amankhwala, thupi ndi mankhwala, komanso ntchito m'mafakitale osiyanasiyana. Kumvetsetsa kusiyana pakati pa magulu awiriwa ndikofunikira kwambiri pakusankha zinthu zoyenera kuti zigwiritsidwe ntchito mwapadera ndikuwongolera momwe amagwirira ntchito m'njira zosiyanasiyana zamafakitale.
