HPMC (Hydroxypropyl Methylcellulose)chinhu chinowanzo shandiswa mukubika ice cream. I cellulose ether inonyungudika mumvura uye inoshandiswa zvakanyanya muindasitiri yezvikafu, kunyanya muzvikafu zvakachengetwa muchando, zvigadzirwa zvemukaka, uye dzimwe nzira dzemiriwo. Zvichienderana nekuti ice cream inoda kuravira kwakakura sei, magadzirirwo ayo, uye kugadzikana kwayo, HPMC inoita basa rakakosha.
1. Tsananguro Yekutanga uye Hunhu hweHPMC
HPMC ipolymer isiri ionic inobva mu cellulose yechisikigo, yakagadziridzwa ne methylation uye hydroxypropylation. Haisi purasitiki yakagadzirwa, asi inobva mu cellulose yechisikigo, ine hunhu hunotevera:
Kunyungudika kwemvura yakawanda: Inonyungudika mumvura inotonhora neinodziya, zvichiita kuti pave nemhinduro inopenya kana inopenya yecolloidal.
Kugadziriswa kwe viscosity yakakura: Mushonga uyu une huwandu hwakakura hwe viscosity, iyo inogona kudzorwa nekuchinja mwero wekutsiva uye huremu hwemamorekuru.
Thermogelation: Inogadzira gel patembiricha yakati uye inodzokera kumvura kana yatonhorera. Haina chepfu uye haina allergies: HPMC yakanyorwa sechikafu chakachengeteka neFAO/WHO pamwe nemakambani mazhinji emishonga yechikafu enyika.
2. Matambudziko mukugadzira Ice Cream
Aizi kirimu isystem yakaoma ine zvikamu zvakawanda ine mhepo, mvura, mafuta, mapuroteni, uye shuga. Kuti muromo unzwe zvakanaka, chimiro chakasimba, uye kugara kwenguva refu, matambudziko anotevera anofanira kugadziriswa panguva yekugadzira:
Kudzora makristaro echando: Makristaro echando akaomarara anoumbwa nyore nyore panguva yekuomesa, zvichikanganisa kusimba kwechinhu chacho.
Kugadzikana kwekunyunguduka: Kuchinja-chinja kwetembiricha kunogona kukonzera kuti chigadzirwa chinyunguduke nekukurumidza kana kuti mvura iite mamina.
Kusanganiswa kwemafuta: Mapombi emafuta anofanira kupararira zvakaenzana kuti muromo ugare wakatsetseka.
Matambudziko ekugadzira ice cream isina mafuta akawanda kana kuti yevegan: Ungachengetedza sei magadzirirwo eice cream yechinyakare pasina kushandisa zvigadzirwa zvemukaka kana kuderedza mafuta?
Matambudziko aya ndiwo anoita basa guru HPMC.
3. Mabasa Makuru eHPMC muIce Cream
3.1. Kukora uye Kuvandudza Kunzwa Kwemuromo
HPMC inowedzera zvakanyanya kusimba kwemvura mumasisitimu emvura, zvichiita kuti mhepo ivharwe zvakanaka panguva yechando, zvichiita kuti muromo unzwe wakapfava uye wakakora. Kunyanya muayisikirimu ine mafuta mashoma, HPMC inogona kutsiva mafuta zvishoma, ichideredza kuomarara kwayo.
3.2. Kudzivirira Kukura kweCrestal yeIce
Munguva yekuchengetwa kwechando, mamorekuru emvura anotama uye anoita kuti makristaro echando akure zvishoma nezvishoma. HPMC inoumba network yakasimba yecolloidal mukati mehurongwa, ichidzivisa kufamba kwakasununguka kwemamorekuru emvura, nokudaro ichidzivisa kukora kwekristaro yechando uye ichibvumira ice cream kuchengetedza chimiro chakasimba mushure mekuomarara-kunyunguduka kakawanda.
3.3. Kuvandudza Kuumbwa kweEmulsification uye Kugadzikana kweFuro
Kunyangwe hazvo HPMC isiri emulsifier yakajairika, kudzorwa kwayo kwe viscosity uye kushanda kwe colloidal membrane zvinogona kudzikamisa mafuta nemabubble emhepo zvisina kunanga, kudzivirira kupatsanurwa kwechikamu kana kuputsika, nokudaro zvichivandudza kuwanda uye kugadzikana kwe ice cream.
3.4. Kuvandudza Hunhu Hwekunyungudutsa
Ice cream ine HPMC haiputsike nekukurumidza panguva yekunyunguduka, asi inonyorova zvishoma nezvishoma. Iyi "inonyunguduka zvishoma nezvishoma" inowedzera kugadzikana kwechigadzirwa panguva yekufambisa, kuratidza, uye kudyiwa.
3.5. Mashandisirwo Ezvekudya Zvemiriwo Nemabasa Anoshanda
Mu ice cream inogadzirwa nemiti kana isina mukaka, HPMC inowanzoshandiswa sechinhu chinotsiva mapuroteni emukaka nemafuta emukaka, zvichiita kuti ive yakatsetseka uye yakasimba seye ice cream yechinyakare. Inewo fiber yekudya, ichivandudza hutano hwechigadzirwa.
4. Mabhenefiti eHPMC
Kuchengetedzwa Kwakanyanya: Sechikafu chakachengeteka chinozivikanwa pasi rose, kudyiwa kwenguva refu hakupi njodzi kuhutano.
Kushandiswa Kwakawanda: Inogona kushandiswa mu ice cream ine mafuta akazara, isina mafuta akawanda, uye isina mukaka.
Kuramba Kupisa Kwakanaka Uye Kugadzikana Kwechando: Yakakodzera kubata kushanduka-shanduka kwekushisa panguva yekuchengetera uye kutakurwa kwecheni inotonhora.
Kuderedza Kuvimba Nezvimwe Zvinosimbisa Muviri: Kana tichienzanisa nekushandisa guar gum, carrageenan, nezvimwewo chete, HPMC inopa mhedzisiro iri nani uye fomura iri nyore.
5. Kuenzanisa Nezvimwe Zvinosimbisa
Zvichienzaniswa neguar gum nelocust bean gum: HPMC inopa kuchinjika kukuru mukugadzirisa viscosity uye kunzwa kwakapfava mumuromo, isinganyanyi kunamira. Zvichienzaniswa necarrageenan: Carrageenan inowanzoita gel yakasimba, nepo HPMC ichipa kutwasuka uye kupfava. Izvi zviviri zvinowanzoshandiswa pamwe chete.
Kana tichienzanisa neCMC (sodium carboxymethylcellulose): CMC inodhura zvishoma asi haikwanise kuramba yakanyungudika nechando, nepo HPMC ichipa mashandiro akanaka kwazvo.
6. Mienzaniso yeMashandisirwo uye Maitiro
Aizi kirimu isina mafuta akawanda: Nekuwedzera HPMC, mafuta anogona kuderedzwa uku uchichengetedza kunzwa kwemuromo kwakapfuma uye chimiro chayo.
Aizi kirimu inogadzirwa nemiti: HPMC inogona kusanganiswa nemukaka wekokonati, mukaka weoat, kana mukaka wesoya kuti kunatsiridze kunaka uye kugadzikana.
Zvigadzirwa zvinoshanda: HPMC, sechinhu chinoshandiswa pakudya chine fiber, inobatsira pakugadzirwa kwepfungwa ye ice cream ine "macalorie mashoma, ine fiber yakawanda".
Nekuwedzera kwekutarisa kwevatengi pahutano nekuchengetedza nguva, kushandiswa kweHPMC mumafuta eice cream kuchawedzera kuwanda. Kunyanya, HPMC inogona kupa rutsigiro rwehunyanzvi kune dzimwe nzira dzemukaka uye mafuta ane shuga shoma, zvichiita kuti zvigadzirwa zvirambe zvichinaka uku zvichisangana nemafambiro ehutano.
HPMCchinhu chakakosha chinosimbisa uye chinogadzirisa ganda mu ice cream. Haisi kungowedzera kugadzikana uye kugadzikana kwe ice cream chete, asiwo inodzivirira kukura kwe ice crystal uye inovandudza hunhu hwekunyunguduka, zvichiita kuti ive yakakodzera kugadzirwa kwe ice cream dzisina mafuta akawanda, dzisina mukaka, uye dzinoshanda. Kana ichienzaniswa nedzimwe colloids uye emulsifiers, HPMC inopa simba rekudzivirira kutonhora uye kunzwa kwakapfava mumuromo, nokudaro ichiita basa rakakosha muindasitiri ye ice cream yemazuva ano.
