Ukusetshenziswa kweCarboxymethyl Cellulose Embonini Yokudla

I-Carboxymethylcellulose (CMC) ihlanganiswa kusuka kumafayibha (fly/lint short, pulp, njll.), sodium hydroxide, kanye ne-monochloroacetic acid. Ngokusho kokusetshenziswa okuhlukile, i-CMC inezincazelo ezintathu: ubumsulwa bomkhiqizo omsulwa ≥ 97%, ubumsulwa bomkhiqizo wezimboni 70-80%, ubumsulwa bomkhiqizo ongahluziwe 50-60%. I-CMC inezinto ezinhle kakhulu ezifana nokujiya, ukumisa okwesikhashana, ukubopha, ukuqiniswa, ukuhlanganisa nokuhlakaza ekudleni. Yiwona owugqinsi wokudla weziphuzo zobisi, imikhiqizo yeqhwa, ujamu, ojeli, amajusi ezithelo, iziqholo, iwayini namathini ahlukahlukene. isizinzisi.

Ukusetshenziswa kwe-CMC embonini yokudla

1. I-CMC ingenza ujamu, ijeli, ijusi yezithelo, isinongo, imayonnaise namathini ahlukahlukene abe ne-thixotropy efanele, futhi ingandisa i-viscosity yabo. Ukwengeza i-CMC enyameni ekheniwe kungavimbela uwoyela namanzi ukuthi angahlangani futhi kusebenze njenge-ejenti yokuguquguquka. Kuphinde kube yi-foam stabilizer ekahle kanye nokucacisa ubhiya. Isamba esingeziwe singaba ngu-5%. Ukwengeza i-CMC ekudleni kwe-pastry kungavimbela uwoyela ukuthi ungaphumi ekudleni kwekhekhe, ukuze ukugcinwa kwesikhathi eside kokudla kwe-pastry kungeke kome, futhi kwenze i-pastry surface bushelelezi futhi ibe ntekenteke ekunambithekeni.

2. Emikhiqizweni yeqhwa—i-CMC inokunyibilika kangcono ku-ayisikhilimu kunezinye izinto ezijiya njenge-sodium alginate, ezingamisa ngokuphelele amaprotheni obisi. Ngenxa yokugcinwa kwamanzi okuhle kwe-CMC, ingakwazi ukulawula ukukhula kwamakristalu eqhwa, ukuze i-ayisikhilimu ibe nesakhiwo esikhulu futhi esigcotshiwe, futhi ayikho insalela yeqhwa lapho ihlafunwa, futhi ukunambitheka kuhle kakhulu. Inani elingeziwe lingu-0.1-0.3%.

3. I-CMC iyisiqiniseko seziphuzo zobisi—uma ijusi yesithelo ifakwa obisini noma obisini olubilile, ingabangela ukuthi iphrotheni yobisi ihlangane ibe yisimo esimisiwe futhi iphume obisini, yenze ukuzinza kweziphuzo zobisi kube kubi futhi kuthambekele ekungeneni. spoilage Kubi. Ikakhulukazi ekugcineni ubisi isiphuzo esingesihle ngokwedlulele. Uma i-CMC yengezwa obisini lwejusi yezithelo noma esiphuzweni sobisi, inani elingeziwe liyi-10-12% yeprotheyini, ingagcina ukufana nokuzinza, ivimbele amaprotheni obisi ekuhlanganiseni, futhi kungabikho imvula, ukuze kuthuthukiswe izinga lesiphuzo sobisi. , futhi ingagcinwa ngokuzinza isikhathi eside. konakele.

4. Ukudla okuyimpuphu - lapho amafutha, ijusi, i-pigment, njll. kudingeka kube yimpushana, ingaxutshwa ne-CMC, futhi ingaba yimpushana kalula ngokumisa isifutho noma ukugxila kwe-vacuum. Incibilika kalula emanzini uma isetshenziswa, futhi inani elingeziwe lingu-2-5%.

5. Ngokuphathelene nokugcinwa kokudla, njengemikhiqizo yenyama, izithelo, imifino, njll., ngemva kokufafaza nge-CMC dilute isixazululo samanzi, kungakhiwa ifilimu elincanyana kakhulu ebusweni bokudla, elingagcina ukudla isikhathi eside. futhi ugcine ukudla kukusha, kuthambile futhi kunambitheka kungashintshile . Futhi ingagezwa ngamanzi uma idla, okuyinto elula kakhulu. Ngaphezu kwalokho, ngenxa yokuthi i-CMC yebanga lokudla ayinabungozi emzimbeni womuntu, ingasetshenziswa kwezokwelapha. Ingasetshenziselwa umuthi wephepha we-CMC, i-emulsified oil engcolisa i-ejenti yomjovo, i-thickener ye-slurry yomuthi, i-grave material yokugcoba, njll.

I-CMC ayigcini nje ngokuba nezinhlelo eziningi ezihlukene embonini yokudla, kodwa futhi inesikhundla esibalulekile embonini yokukhanya, izindwangu, ukwenza amaphepha, ukuphrinta nokudaya, uphethiloli namakhemikhali ansuku zonke.
