Ukupakishwa kokudla kuthatha indawo ebalulekile ekukhiqizweni nasekusabalaliseni ukudla, kodwa ngenkathi kuletha izinzuzo nokunethezeka kubantu, kuphinde kube nezinkinga zokungcoliswa kwemvelo ezibangelwa ukupakisha imfucuza. Ngakho-ke, eminyakeni yamuva nje, ukulungiswa nokusetshenziswa kwamafilimu okupakisha okudliwayo kuye kwenziwa ekhaya nakwamanye amazwe. Ngokocwaningo, ifilimu yokupakisha edliwayo inezici zokuvikelwa kwemvelo okuluhlaza, ukuphepha kanye nokubola kwezinto eziphilayo. Ingaqinisekisa ikhwalithi yokudla ngokusebenzisa ukusebenza kokumelana komoyampilo, ukumelana nomswakama kanye nokufuduka kwe-solute, ukuze kwandiswe isikhathi seshelufu sokudla. Ifilimu yokupakisha yangaphakathi edliwayo ngokuyinhloko yenziwe ngezinto eziphilayo ze-macromolecular, enamandla athile omshini kanye nowoyela ophansi, umoya-mpilo kanye nokungena kwamanzi, ukuze kuvinjwe ukuvuza kwejusi yesinongo noma uwoyela, futhi isinongo sizoba manzi futhi sikhuthale Ngaphezu kwalokho. , inokuncibilika okuthile emanzini futhi kulula ukuyidla. Ngokuthuthuka okusheshayo komkhakha wezwe wami wokulungisa ukudla okulula, ukusetshenziswa kwamafilimu okupakisha angaphakathi adliwayo kuma-condiments kuzokhula kancane kancane esikhathini esizayo.
01. I-sodium carboxymethyl cellulose
I-sodium carboxymethyl cellulose (I-CMC-Na) iwukuphuma kwe-carboxymethylated ku-cellulose futhi iyishingamu ye-ionic cellulose ebaluleke kakhulu. I-sodium carboxymethyl cellulose imvamisa iyinhlanganisela ye-anionic polymer elungiswa ngokusabela i-cellulose yemvelo nge-caustic alkali ne-monochloroacetic acid, enesisindo samangqamuzana asuka ezinkulungwaneni ezimbalwa kuya ezigidini. I-CMC-Na iyimpushana emhlophe noma i-granular, ayinaphunga, ayinambitheki, i-hygroscopic, kulula ukuyihlakaza emanzini ukuze yakhe isixazululo se-colloidal esobala.
I-sodium carboxymethyl cellulose iwuhlobo lwe-thickener. Ngenxa yezakhiwo zayo ezinhle zokusebenza, iye yasetshenziswa kakhulu embonini yokudla, futhi iye yakhuthaza nokuthuthukiswa okusheshayo nokunempilo kwemboni yezokudla ngezinga elithile. Isibonelo, ngenxa yomphumela wayo wokuqina kanye ne-emulsifying, ingasetshenziswa ukuzinzisa iziphuzo ze-yogurt futhi kwandiswe i-viscosity yesistimu ye-yogurt; ngenxa yezindawo zayo ezithile ze-hydrophilicity kanye ne-rehydration, ingasetshenziswa ukuthuthukisa ukusetshenziswa kwe-pasta njengesinkwa nesinkwa esishisayo. ikhwalithi, yelula impilo yeshalofu yemikhiqizo ye-pasta, futhi uthuthukise ukunambitheka; ngoba inomphumela othile we-gel, ivumela ukwakheka okungcono kwejeli ekudleni, ngakho-ke ingasetshenziswa ukwenza i-jelly ne-jam; ingasetshenziswa futhi njengefilimu enamathelayo edliwayo Impahla ihlanganiswe nezinye izingqimba futhi ifakwe ebusweni bokunye ukudla, okungagcina ukudla kusha kuze kube sezingeni eliphezulu, futhi ngenxa yokuthi kuyizinto ezidliwayo, ngeke kubangele okubi. imiphumela empilweni yomuntu. Ngakho-ke, i-CMC-Na yezinga lokudla, njengesengezo sokudla esifanele, isetshenziswa kabanzi ekukhiqizeni ukudla embonini yokudla.
02. Ifilimu edliwayo ye-sodium carboxymethylcellulose
I-Carboxymethyl cellulose iyi-ether ye-cellulose engakha amafilimu amahle kakhulu ngendlela yamajeli ashisayo, ngakho-ke isetshenziswa kakhulu ezimbonini zemithi nezokudla. Ifilimu ye-Carboxymethyl cellulose iwumoya-mpilo osebenza kahle, i-carbon dioxide kanye ne-lipid barrier, kodwa alikwazi ukumelana nokudluliswa komhwamuko wamanzi. Amafilimu adliwayo angathuthukiswa ngokungeza izinto ze-hydrophobic, njenge-lipids, kwisixazululo sokwenza ifilimu Ngakho-ke, yaziwa nangokuthi i-lipid derivative engase ibe khona.
1. Ifilimu edliwayo ye-CMC-lotus yempande yesitashi-yesihlahla setiye ingahlangabezana nezidingo zokuluhlaza, ukuphepha nokungangcoli, okungagcini nje ngokuqinisekisa izinga lokudla kodwa futhi kunganciphisi umphumela wokupakisha. Kulindeleke ukuthi ithuthukiswe futhi isetshenziswe kuma-noodle asheshayo, ikhofi esheshayo, i-oatmeal esheshayo kanye nobisi lwe-soya powder esikhathini esizayo. Isikhwama sokupakisha sangaphakathi sithatha indawo yefilimu yepulasitiki yendabuko.
2. Ukusebenzisa i-carboxymethyl cellulose njengesisekelo sokwenza ifilimu, i-glycerin njenge-plasticizer, nokwengeza isitashi somdumbula njengento ewusizo ukulungisa ifilimu eyinhlanganisela edliwayo, ifaneleka kakhulu ukupakishwa kwamaphakethe kaviniga namaphakethe wempuphu agcinwe zingakapheli izinsuku ezingama-30 kanye namafutha esikhathi eside. ifilimu yokugoqa.
3. Ukusebenzisa impushana yekhasi likalamula, i-glycerin, ne-sodium carboxymethylcellulose njengezinto ezingavuthiwe ezakha ifilimu zamafilimu adliwayo ekhasi likalamula.
4. Kusetshenziswa isixazululo samanzi se-sodium carboxymethyl cellulose njengesithwali kanye ne-nobiletin yebanga lokudla njengento eluhlaza, kwalungiselelwa ukuhlanganiswa kwento ehlanganisiwe ye-nobiletin-sodium carboxymethyl cellulose ukwandisa isikhathi seshalofu likakhukhamba.
