Kwishishini lokutya, i-HPMC inokuphucula i-farinaceous kunye ne-tensile iipropathi zentlama. Ukongeza, ukongezwa kweHydroxypropyl Methyl cellulose etherHPMCkunciphisa ukwanda kwamanzi okukhenkceza kwintlama ngexesha lokugcinwa komkhenkce, ngaloo ndlela kuthintela umphumo we-ice crystallization kwisakhiwo sothungelwano lwentlama. Umonakalo ugcina uzinzo kunye nokunyaniseka kwesakhiwo sayo, ngaloo ndlela unikezela isiqinisekiso somgangatho wemveliso yokugqibela. Kwelinye icala, ukongezwa HPMC kwakhona ulawulo elungileyo umgangatho kunye nesiphumo uphuculo kwisonka steamed. Kwiisampulu ezingakhenkcezisiweyo, ukongezwa kwe-HPMC kwandise umthamo othile wesonka esiqhunyiweyo kunye nokuphucula iimpawu zesonka esiqhumayo; ngelixa kunye nokwandiswa kwexesha lomkhenkce, ukongezwa kwe-HPMC kwanqanda ukuwohloka komgangatho wesonka esiqhumayo esenziwe kwisidanga sentlama ekhenkcezisiweyo. Oku kubonisa ukuba i-HPMC ingasetyenziswa ekuqhubeni intlama ekhenkcezisiweyo ngesonka esiqhunyisiweyo njengemveliso yokugqibela, kwaye inempembelelo engcono ekuphuculeni umgangatho wesonka esiqhunyiswayo.
(2) Iimvavanyo zibonise ukuba isakhiwo se-gluten ngaphandle kwe-HPMC satshatyalaliswa ngenxa yokubunjwa kunye nokukhula kweekristale ze-ice, i-modulus elastic yehla kakhulu, umxholo we-thiol wamahhala wanda kakhulu, kwaye i-microstructure yenethiwekhi yatshatyalaliswa; nangona kunjalo, ukongezwa kwe-HPMC kunokuthintela ngokufanelekileyo Olu tshintsho, ngakumbi xa imali yokongeza i-2%, xa kuthelekiswa neqela lokulawula, umxholo wamaqela e-sulfhydryl yamahhala, umxholo wamanzi anqabileyo kunye nokuvezwa kwamaqela e-hydrophobic kwancitshiswa, ngelixa ulwakhiwo lwesibini kunye ne-microscopic yenethiwekhi ye-gluten yahlala ngokulinganayo. Oku kungenxa yokuba i-HPMC inokunciphisa ukuhamba kwamanzi kwaye inciphise ukwanda komthamo wamanzi anokukhenkceka, ngaloo ndlela inciphisa umonakalo wokuhambelana kwendawo kunye nesakhiwo sothungelwano lweprotheni yegluten ngamakristale omkhenkce.
(3) Uvavanyo lufumene ukuba emva kweentsuku ezingama-60 zokugcinwa komkhenkce, iimpawu ze-gelatinization zesitashi zonke zanda, i-gelatinization enthalpy yanda kakhulu, ngelixa amandla e-gel ye-starch paste ancipha, nto leyo ebonisa ukuba isakhiwo se-starch satshintshwa (i-crystallinity ehambelanayo yanda. kakhulu). , iqondo lomonakalo wesitashi landa); nangona kunjalo, ukumiswa kwesitatshi kunye ne-HPMC yongezwa, isakhiwo se-starch sahlala sizinzile emva komkhenkce, ngaloo ndlela sinciphisa iqondo lotshintsho kwiimpawu ze-gelatinization, i-gelatinization enthalpy, amandla ejeli, njl. kulwakhiwo kunye neepropathi zegranule zesitatshi zomthonyama.
(4) Uvavanyo lubonisa ukuba xa kuthelekiswa neqela lolawulo, ukongezwa kwe-HPMC kunokugcina ngcono umsebenzi wokubiliswa kwegwele, ukuthintela ukuhla kokuphakama kwentlama kunye nenani lokusinda kwegwele emva komkhenkce kwiintsuku ezingama-60, ngokunciphisa uhlobo lokunciphisa olungaphandle. Izinga lokunyuka komxholo we-glutathione, kwaye ngaphakathi koluhlu oluthile, umphumo wokukhusela we-HPMC wawulungelelaniswe kakuhle kunye nemali yokongeza. Oku kubonisa ukuba i-HPMC inokukhusela igwele ngokuthintela ukubunjwa kunye nokukhula kweekristale zomkhenkce.
6.2 Ukujonga
(1) Ukuqhubela phambili nokufunda ngokucwangcisiweyo iziphumo zokongeza i-HPMC kwiqondo lobushushu leglasi (H) yentlama ekhenkcezisiweyo, i-kinetics yokuvubela yegwele kunye nencasa yesonka esiqhunyisweyo, kunye nokwakheka, ukukhula, kunye nokwabiwa kwakhona kweekristale zomkhenkce Intlama ekhenkcezisiweyo, njl.njl. Ngoko ke, iintlobo ezintsha ezinokumelana noxinzelelo olunamandla olulungele intlama ekhenkcezisiweyo zakhethwa, kwaye ireferensi yokuhanjiswa kwentlama ekhenkcezisiweyo kunye nekhonkco elibandayo kunye nokunye ukutya okunomkhenkce.

(3) Lungiselela ngakumbi iresiphi yentlama ekhenkcezisiweyo kunye nemilinganiselo yenkqubo ehambelana neyona mveliso yesonka esiqhunyiswayo, ukuze kuphuculwe kwaye kuphuculwe umgangatho wemveliso yesonka ekhenkcezisiweyo, kwaye kwangaxeshanye ukulawula nokunciphisa imveliso. iindleko. Ukongeza, ukusetyenziswa kwe-HPMC kwintlama enomkhenkce yeemveliso zepasta zaseTshayina nazo zinokukwandiswa, kunye noyilo oluninzi kunye neentlobo zeemveliso zinokuphuhliswa ukuhlangabezana neemfuno zabathengi.
