Muindasitiri yechikafu, HPMC inogona kuvandudza iyo farinaceous uye tensile zvimiro zvehupfu. Mukuwedzera, kuwedzerwa kweHydroxypropyl Methyl cellulose etherHPMCinoderedza kuwedzera kwemvura inotonhora mumukanyiwa panguva yekutonhora kwekuchengetera, nokudaro ichidzivisa kushanda kwechando chekristalllization pane poda network structure. Iko kukanganisa kunochengetedza kugadzikana kwehukama uye kutendeseka kwechimiro chayo, nokudaro kupa chivimbiso chehutano hwechigadzirwa chekupedzisira. Kune rimwe divi, kuwedzerwa kweHPMC zvakare kune yakanaka yemhando yekudzora uye kugadzirisa mhedzisiro pachingwa chakabikwa. Kune masampuli asina kuomeswa, kuwedzerwa kweHPMC kwakawedzera huwandu chaihwo hwechingwa chakabikwa uye kwakavandudza hunhu hwechingwa chakabikwa; nepo nekuwedzera kwenguva yechando, kuwedzerwa kweHPMC kwakadzivisa kuparara kwehutano hwechingwa chakabikwa chakagadzirwa kubva padhigirii yehupfu yechando. Izvi zvinoratidza kuti HPMC inogona kuiswa pakugadziriswa kwekanyiwa yakaomeswa nechingwa chakabikwa sechigadzirwa chekupedzisira, uye ine mhedzisiro iri nani pakuvandudza kunaka kwechingwa chakabikwa.
(2) Miedzo yakaratidza kuti chimiro che gluten chisina HPMC chakaparadzwa nekuda kwekuumbwa uye kukura kwekrisiti yechando, elastic modulus yakaderera zvikuru, yakasununguka thiol content yakawedzera zvakanyanya, uye network microstructure yakaparadzwa; zvisinei, kuwedzerwa kweHPMC kunogona kuvharidzira zvinobudirira Shanduko iyi, kunyanya kana mari yekuwedzera iri 2%, kana ichienzaniswa neboka rinodzora, zviri mukati memahara sulfhydryl mapoka, zviri mukati memvura inotonhora uye kuratidzwa kwemapoka ehydrophobic zvakaderedzwa, nepo. iyo yechipiri chimiro uye microscopic network chimiro che gluten chakaramba chakadzikama. Izvi zvinodaro nekuti HPMC inogona kuderedza kufamba kwemvura uye kudzikamisa kuwedzera kwemvura inotonhora yemukati, nekudaro ichidzikisa kukuvadzwa kwenzvimbo ye conformation uye network chimiro che gluten protein nema ice crystals.
(3) Kuedza kwakawana kuti mushure memazuva makumi matanhatu ekuchengetedza kwechando, gelatinization maitiro e starch akawedzera, gelatinization enthalpy yakawedzera zvakanyanya, asi simba rejeri re starch paste rakaderera, izvo zvakaratidza kuti chimiro che starch chakashandurwa (hukama hwekristallini hwakawedzera. zvakanyanya). , chiyero chekukuvadza starch chakawedzera); zvisinei, iyo starch kumiswa neHPMC yakawedzera, chimiro che starch chakaramba chakadzikama mushure mechando, nokudaro kuderedza dhigirii yekuchinja kwegelatinization maitiro, gelatinization enthalpy, gel simba, nezvimwewo. pane chimiro uye zvimiro zvekuzvarwa starch granules.
(4) Kuedza kunoratidza kuti kana ichienzaniswa neboka rekutonga, kuwedzera kweHPMC kunogona kuchengetedza zvirinani basa rekuvirisa kwembiriso, kudzivisa kuderera kwekuvirisa kwehupfu uye nhamba yekupona kwembiriso mushure mechando kwemazuva makumi matanhatu, nokudaro kuderedza rudzi rwekuderedza extracellular. Kuwedzera mwero we glutathione zvemukati, uye mukati meimwe nhanho, kudzivirira kweHPMC kwakanyatso kuwirirana nehuwandu hwayo hwekuwedzera. Izvi zvinoratidza kuti HPMC inogona kuchengetedza mbiriso nekudzivisa kuumbwa uye kukura kwemakristasi echando.
6.2 Outlook
(1) Kuenderera mberi nekuongorora zvakarongeka mhedzisiro yekuwedzera HPMC pane tembiricha yegirazi (H) yekanyiwa yakaomeswa, iyo yekuvirisa kinetics yembiriso uye kunhuwirira kwechingwa chakabikwa, pamwe nekuumbwa, kukura, uye kugovaniswazve kwemakristasi echando mu. Kanyiwa yakaomeswa nechando, nezvimwewo. Naizvozvo, mhando itsva dzine simba rekudzivirira kushushikana kwakasimba kwakakodzera mukanyiwa wechando dzakasarudzwa, uye chirevo chekugadzirwa uye kutonhora kwekutakura kwehupfu hwakaomeswa uye kunyange zvimwe zvekudya zvakaomeswa zvakapihwa.
(2) Uyezve dzidza maitiro ekuvandudza kweHPMC pamhando yekanyiwa yakaomeswa nechando uye zvigadzirwa zvayo panguva yakareba yekutonhora yekuchengetera nguva, uye ongorora mashandisirwo eHPMC mune mamwe marudzi ehupfu hwakaomeswa nechando.
(3) Uyezve gadzirisa iyo yakaomeswa mukanyiwa resipi uye magadzirirwo maparamita anoenderana nekugadzirwa chaiko kwechingwa chakabikwa, kuitira kuti uvandudze uye uwedzere kunaka kwechingwa chakaomeswa nechando, uye panguva imwe chete kudzora uye kuderedza kugadzirwa. mutengo. Uye zvakare, kushandiswa kweHPMC mune yakaomeswa mukanyiwa Chinese-style pasta zvigadzirwa zvinogona zvakare kuwedzerwa, uye mamwe magadzirirwo uye marudzi ezvigadzirwa anogona kuvandudzwa kuzadzisa zvinodiwa nevatengi.
