Embonini yokudla, i-HPMC ingathuthukisa izakhiwo ze-farinaceous neziqinile zenhlama. Ngaphezu kwalokho, ukungezwa kwe-Hydroxypropyl Methyl cellulose etherI-HPMCkunciphisa ukwanda kokuqukethwe kwamanzi okuqandiseka enhlama ngesikhathi sokugcinwa kweqhwa, ngaleyo ndlela kuvimbela umphumela we-ice crystallization esakhiweni senethiwekhi yenhlama. Umonakalo ugcina ukuzinza okuhlobene nobuqotho besakhiwo sawo, ngaleyo ndlela unikeze isiqinisekiso sekhwalithi yomkhiqizo wokugcina. Ngakolunye uhlangothi, ukungezwa kwe-HPMC nakho kunokulawula okuhle kwekhwalithi nomthelela wokuthuthukisa isinkwa esishisayo. Kumasampula angaqandisiwe, ukungezwa kwe-HPMC kwenyuse umthamo othize wesinkwa esishunqisiwe futhi kwathuthukisa izakhiwo zesinkwa esishuthiwe; ngenkathi nokwengezwa kwesikhathi sokuqanda, ukungezwa kwe-HPMC kuvimbe ukuwohloka kwekhwalithi yesinkwa esishisayo esenziwe ngedigri yenhlama efriziwe. Lokhu kukhombisa ukuthi i-HPMC ingasetshenziswa ekucutshungulweni kwenhlama efriziwe nesinkwa esishisayo njengomkhiqizo wokugcina, futhi inomthelela ongcono ekuthuthukiseni ikhwalithi yesinkwa esishisayo.
(2) Ukuhlolwa kubonise ukuthi isakhiwo se-gluten ngaphandle kwe-HPMC sabhujiswa ngenxa yokwakheka nokukhula kwamakristalu eqhwa, i-modulus elastic yehla kakhulu, okuqukethwe kwe-thiol yamahhala kwanda kakhulu, futhi i-microstructure yenethiwekhi yabhujiswa; kodwa-ke, ukungezwa kwe-HPMC kungavimbela ngokuphumelelayo Lolu shintsho, ikakhulukazi uma inani elingeziwe liyi-2%, uma liqhathaniswa neqembu lokulawula, okuqukethwe kwamaqembu e-sulfhydryl yamahhala, okuqukethwe kwamanzi aqhwa kanye nokuvezwa kwamaqembu e-hydrophobic kwancishiswa, kuyilapho isakhiwo sesibili kanye ne-microscopic network network ye-gluten yahlala iqinile. Lokhu kungenxa yokuthi i-HPMC inganciphisa ukuhamba kwamanzi futhi ikhawulele ukwanda kokuqukethwe kwamanzi aqandisekayo, ngaleyo ndlela yehlise umonakalo wokuvumelana kwendawo kanye nesakhiwo senethiwekhi ye-gluten amaprotheni ngamakristalu eqhwa.
(3) Ukuhlolwa kwathola ukuthi ngemva kwezinsuku ezingu-60 zokugcinwa eqandisiwe, izici ze-gelatinization zesitashi zonke zanda, i-gelatinization enthalpy yanda kakhulu, kuyilapho amandla ejeli okunamathisela isitashi ehla, okubonisa ukuthi isakhiwo sesitashi sishintshiwe (i-crystallinity ehlobene yanda. kakhulu). , izinga lomonakalo wesitashi lenyuka); Nokho, ukumiswa isitashi nge HPMC wanezela, isakhiwo isitashi sahlala kuqhathaniswa uzinzile ngemva okokuqandisa, ngaleyo ndlela kunciphisa izinga izinguquko gelatinization izici, gelatinization enthalpy, amandla gel, njll Kubonisa ukuthi ukwengeza HPMC kungavimbela umphumela amakristalu eqhwa. ngesakhiwo kanye nezakhiwo zama-starch granules zomdabu.
(4) Ukuhlolwa kukhombisa ukuthi uma kuqhathaniswa neqembu elilawulayo, ukungezwa kwe-HPMC kungagcina kangcono umsebenzi wokuvutshelwa kwemvubelo, kuvimbele ukwehla kokuvutshelwa kwenhlama kanye nenombolo yokusinda yemvubelo ngemuva kokuqandisa izinsuku ezingama-60, ngaleyo ndlela kunciphisa uhlobo lokunciphisa ama-extracellular. Izinga lokukhuphuka lokuqukethwe kwe-glutathione, futhi phakathi kwebanga elithile, umthelela wokuvikela we-HPMC wawuhlotshaniswa kahle nenani layo elingeziwe. Lokhu kuphakamisa ukuthi i-HPMC ingavikela imvubelo ngokuvimbela ukwakheka nokukhula kwamakristalu eqhwa.
6.2 I-Outlook
(1) Ukuqhubeka nokutadisha ngokuhlelekile imiphumela yokwengeza i-HPMC ekushiseni kwengilazi (H) yenhlama eqandisiwe, i-fermentation kinetics ye-yeast kanye nokunambitheka kwesinkwa esishisayo, kanye nokwakheka, ukukhula, kanye nokwabiwa kabusha kwamakristalu eqhwa inhlama eqandisiwe, njll. Ngakho-ke, kwakhethwa izinhlobo ezintsha ezinokumelana nokucindezeleka okuqinile ezifanele inhlama eqandisiwe, kwanikezwa nereferensi yokukhiqiza kanye nokuthuthwa okubandayo kwenhlama efriziwe kanye nokunye ukudla okufriziwe.
(2) Funda kabanzi ngomthelela wokuthuthukisa we-HPMC kwikhwalithi yenhlama eqandisiwe kanye nemikhiqizo yayo phakathi nesikhathi eside sokuqandisa, futhi uhlole ukusetshenziswa kwe-HPMC kwezinye izinhlobo zenhlama eqandisiwe.
(3) Lungiselela futhi iresiphi yenhlama efriziwe kanye nemingcele yenqubo ehambisana nokukhiqizwa kwangempela kwesinkwa esishisayo, ukuze kuthuthukiswe futhi kuthuthukiswe ikhwalithi yomkhiqizo wesinkwa esiqandisiwe, futhi ngesikhathi esifanayo ulawule futhi unciphise ukukhiqizwa. izindleko. Ngaphezu kwalokho, ukusetshenziswa kwe-HPMC enhlama eqandisiwe imikhiqizo ye-pasta yaseShayina nayo inganwetshwa, futhi imiklamo eminingi nezinhlobo zemikhiqizo zingathuthukiswa ukuze kuhlangatshezwane nezidingo zabathengi.
