Sodium carboxymethyl selulose, bita carboxymethyl selulose (CMC) ni ubwoko bwa fibre fibre fibre ether yateguwe no guhindura imiti ya selile. Imiterere yacyo ni D-glucose igice binyuze muri β (1 → 4) glycosidic ihuza ibice. Imikoreshereze ya CMC ifite ibyiza byinshi kurenza ibindi byongera ibiryo.
01 CMC ikoreshwa cyane mubiribwa
(1) CMC ifite ituze ryiza
Mu biribwa bikonje nka popsicles na ice cream, irashobora kugenzura imiterere ya kirisita ya ice, kongera umuvuduko wo kwaguka no gukomeza imiterere imwe, kurwanya gushonga, kugira uburyohe kandi bworoshye, kandi byera ibara.
Mu mata y’amata, yaba amata meza, amata yimbuto cyangwa yogurt, irashobora kwitwara hamwe na poroteyine murwego rwa isoelectric point ya pH agaciro ka pH (PH4.6) kugirango ikore urwego rufite imiterere igoye, ifitiye akamaro u ituze rya emulsiyo no Kunoza poroteyine.
(2) CMC irashobora kongerwamo izindi stabilisateur na emulisiferi
Mu biribwa n'ibinyobwa, ababikora muri rusange bakoresha stabilisateur zitandukanye, nka: xanthan gum, guar gum, carrageenan, dextrin, nibindi. Emulifiseri nka: glycerol monostearate, estride acide acide, nibindi, byuzuzanya kugirango byuzuzanye. ibyiza kandi bigira uruhare runini kugirango ugabanye ibiciro byumusaruro.
(3) CMC ifite pseudoplastique
Ubukonje bwa CMC burahinduka mubushyuhe butandukanye. Mugihe ubushyuhe buzamutse, ubwiza bwigisubizo buragabanuka, naho ubundi; iyo imbaraga zo gukata zibaho, ubwiza bwa CMC buzagabanuka, kandi niyongera ryimbaraga zogosha, ubwiza buzagabanuka. Iyi mitungo ifasha CMC kugabanya imitwaro yibikoresho no kunoza imikorere ya homogenisation mugihe ikangura, homogenizing, hamwe nogutwara imiyoboro, itagereranywa nabandi stabilisateur.
02 Ibisabwa
Nka stabilisateur ikora neza, CMC izagira ingaruka ku ngaruka zayo iyo ikoreshejwe nabi, ndetse igatuma ibicuruzwa bivaho. Kubwibyo, kuri CMC, ni ngombwa cyane gukwirakwiza byuzuye kandi bingana igisubizo kugirango tunoze imikorere yacyo, kugabanya dosiye, kuzamura ubwiza bwibicuruzwa no kongera umusaruro. By'umwihariko, hagomba kwitabwaho kuri buri cyiciro:
(1) Ibigize
1. Uburyo bwihuse bwo gutatanya ubwoya hamwe nimbaraga za mashini
Ibikoresho byose bifite ubushobozi bwo kuvanga birashobora gukoreshwa kugirango bifashe CMC gutatanya mumazi. Binyuze mu kogosha byihuse, CMC irashobora gushiramo amazi mumazi kugirango umuvuduko wa CMC wihute.
Bamwe mubakora ubu bakoresha amazi-ifu ivanga cyangwa ibigega bivanga umuvuduko mwinshi.
2. Uburyo bwo gukwirakwiza isukari yumye
Kuvanga neza na CMC hamwe nisukari isukuye ku kigereranyo cya 1: 5, hanyuma ukayinyanyagiza buhoro buhoro uhora ubyutsa kugirango ushire CMC burundu.
3. Shonga mumazi yisukari yuzuye
Nka karamel, nibindi, birashobora kwihutisha iseswa rya CMC.
(2) Kongera aside
Ku binyobwa bimwe na bimwe bya acide, nka yogurt, ibicuruzwa birwanya aside bigomba guhitamo. Niba bikozwe mubisanzwe, ubwiza bwibicuruzwa burashobora kunozwa kandi imvura igwa hamwe nibice bishobora gukumirwa.
1. Iyo wongeyeho aside, ubushyuhe bwo kongeramo aside bugomba kugenzurwa cyane, muri rusange ≤20 ° C.
2. Ubwinshi bwa acide bugomba kugenzurwa kuri 8-20%, hasi nibyiza.
3. Kwiyongera kwa acide bifata uburyo bwo gutera, kandi byongewe kumyerekezo igaragara yikigereranyo cya kontineri, muri rusange iminota 1-3.
4. Umuvuduko mwinshi n = 1400-2400r / m
(3) Abahuje ibitsina
1. Intego yo kwigana
Amazi y'ibiryo ya homogeneous, arimo ibinure, CMC igomba kongerwamo na emulisiferi, nka monoglyceride, umuvuduko wa homogenisation ni 18-25mpa, n'ubushyuhe ni 60-70 ° C.
2. Intego yo kwegereza ubuyobozi abaturage
Homogenisation, niba ibintu bitandukanye mubyiciro byambere bidahuye neza, haracyari uduce duto duto, bigomba guhuzwa, igitutu cya homogenisation ni 10mpa, naho ubushyuhe ni 60-70 ° C.
(4) Kurimbuka
CMC ku bushyuhe bwo hejuru, cyane cyane iyo ubushyuhe buri hejuru ya 50 ° C igihe kirekire, ubwiza bwa CMC bufite ubuziranenge buzagabanuka ku buryo budasubirwaho. Ubukonje bwa CMC bwabakora muri rusange buzagabanuka cyane kuri 80 ° C muminota 30, bityo sterisisation cyangwa barisation irashobora gukoreshwa. Uburyo bwa Sterilisation bwo kugabanya igihe cya CMC ku bushyuhe bwo hejuru.
(5) Ubundi buryo bwo kwirinda
1. Ubwiza bw’amazi bwatoranijwe bugomba kuba busukuye kandi bugatunganywa amazi ya robine bishoboka. Erega amazi ntagomba gukoreshwa kugirango yirinde kwandura mikorobe no kugira ingaruka kubicuruzwa.
2. Ibikoresho byo gushonga no kubika CMC ntibishobora gukoreshwa mubikoresho byibyuma, ariko birashobora gukoreshwa ibikoresho byuma bidafite ingese, ibase ryibiti, cyangwa ibikoresho bya ceramic. Irinde gucengera kwa ion zingana.
3. Nyuma yo gukoresha buri gihe CMC, umunwa wumufuka wapakiye ugomba guhambirirwa cyane kugirango wirinde kwinjiza amazi no kwangirika kwa CMC.
03 Ibisubizo kubibazo mugukoresha CMC
Nigute ubucucike buke, hagati-yubukonje, hamwe nubwinshi-butandukanye cyane muburyo butandukanye? Hoba hariho itandukaniro muburyo buhoraho?
Subiza:
Byumvikane ko uburebure bwurunigi rwa molekile butandukanye, cyangwa uburemere bwa molekile buratandukanye, kandi bugabanijemo ubukonje buke, buciriritse nuburebure. Nibyo, imikorere ya macroscopique ihuye nubwiza butandukanye. Ihuriro rimwe rifite ubwiza butandukanye, ibicuruzwa bihamye hamwe na aside igereranije. Umubano utaziguye ahanini ushingiye kubisubizo byibicuruzwa.
Nibihe bikorwa byihariye byibicuruzwa bifite urwego rwo gusimbuza hejuru ya 1.15? Muyandi magambo, urwego rwo hejuru rwo gusimbuza, imikorere yihariye yibicuruzwa yazamuwe?
Subiza:
Igicuruzwa gifite urwego rwo hejuru rwo gusimbuza, kwiyongera kwamazi, no kugabanya cyane pseudoplastique. Ibicuruzwa bifite ubwiza bumwe bifite urwego rwo hejuru rwo gusimburwa no kumva kunyerera. Ibicuruzwa bifite urwego rwo hejuru rwo gusimbuza bifite igisubizo kibengerana, mugihe ibicuruzwa bifite urwego rusange rwo gusimbuza bifite igisubizo cyera.
Nibyiza guhitamo ububobere buciriritse bwo gukora ibinyobwa bya poroteyine bisembuye?
Subiza:
Ibicuruzwa bito n'ibiciriritse bito, urugero rwo gusimburwa ni 0,90, nibicuruzwa bifite aside irwanya aside.
Nigute CMC ishobora gushonga vuba? Rimwe na rimwe, nyuma yo guteka, irashonga buhoro.
Subiza:
Kuvanga nizindi colloide, cyangwa gutatanya hamwe na 1000-1200 rpm agitator.
Ikwirakwizwa rya CMC ntabwo ari ryiza, hydrophilicity ni nziza, kandi biroroshye guhuriza hamwe, kandi ibicuruzwa bifite impamyabumenyi ihanitse iragaragara! Amazi ashyushye ashonga vuba kuruta amazi akonje. Guteka ntibisanzwe. Guteka igihe kirekire kubicuruzwa bya CMC bizasenya imiterere ya molekuline kandi ibicuruzwa bizabura ubukonje!
