Sodium carboxymethyl cellulose, ake magana a kai a matsayin carboxymethyl cellulose (CMC) wani irin high-polymer fiber ether shirya ta sinadaran gyara na halitta cellulose. Tsarinsa shine naúrar D-glucose galibi ta hanyar β (1→4) abubuwan haɗin haɗin gwiwar glycosidic. Amfani da CMC yana da fa'idodi da yawa akan sauran masu kaurin abinci.
01 Ana amfani da CMC sosai a abinci
(1) CMC yana da kwanciyar hankali mai kyau
A cikin abinci mai sanyi irin su popsicles da ice cream, yana iya sarrafa samuwar lu'ulu'u na kankara, haɓaka haɓakar haɓakawa da kula da tsari iri ɗaya, tsayayya da narkewa, samun ɗanɗano mai kyau da santsi, da farar launi.
A cikin samfuran kiwo, ko madara mai ɗanɗano ne, madarar 'ya'yan itace ko yogurt, yana iya amsawa tare da furotin a cikin kewayon ma'aunin isoelectric na ƙimar pH (PH4.6) don samar da hadaddun tare da tsarin hadaddun, wanda ke da amfani ga kwanciyar hankali na emulsion da Inganta haɓakar furotin.
(2) CMC za a iya haɗa shi tare da wasu stabilizers da emulsifiers
A cikin kayan abinci da abin sha, masana'antun gabaɗaya suna amfani da na'urori daban-daban, kamar: xanthan gum, guar gum, carrageenan, dextrin, da sauransu. abũbuwan amfãni kuma suna taka rawar haɗin gwiwa don rage farashin samarwa.
(3) CMC yana da pseudoplasticity
Dankowar CMC tana juyawa a yanayin zafi daban-daban. Yayin da zafin jiki ya tashi, dankon maganin yana raguwa, kuma akasin haka; lokacin da ƙarfin shear ya kasance, danko na CMC zai ragu, kuma tare da karuwa da karfi, danko zai ragu. Wadannan kaddarorin suna ba da damar CMC don rage nauyin kayan aiki da haɓaka haɓakar haɓakar haɓakawa yayin motsawa, homogenizing, da jigilar bututun, wanda sauran masu daidaitawa ba su daidaita.
02 Bukatun tsari
A matsayin ingantaccen stabilizer, CMC zai shafi tasirin sa idan aka yi amfani da shi ba daidai ba, har ma ya sa samfurin ya rushe. Sabili da haka, don CMC, yana da matukar muhimmanci a cika da kuma rarraba maganin don inganta ingancinsa, rage yawan adadin, inganta ingancin samfurin da ƙara yawan amfanin ƙasa. Musamman, ya kamata a biya hankali ga kowane mataki na tsari:
(1) Sinadaran
1. Hanyar watsawa mai sauri mai sauri tare da ƙarfin injiniya
Ana iya amfani da duk kayan aiki tare da ikon haɗawa don taimakawa CMC don watsawa cikin ruwa. Ta hanyar sausaya mai saurin gaske, ana iya jika CMC cikin ruwa daidai gwargwado don saurin rushewar CMC.
Wasu masana'antun a halin yanzu suna amfani da mahaɗin foda na ruwa ko tankuna masu sauri.
2. Sugar busassun hadawa watsawa hanya
Mix da kyau tare da CMC da granulated sugar a wani rabo na 1: 5, da kuma yayyafa shi a hankali a karkashin akai stirring don cikakken narkar da CMC.
3. Narke a cikin cikakken ruwan sukari
Irin su caramel, da dai sauransu, na iya hanzarta rushewar CMC.
(2) Qarin acid
Don wasu abubuwan sha na acidic, kamar yogurt, dole ne a zaɓi samfuran da ke jure acid. Idan ana sarrafa su akai-akai, ana iya inganta ingancin samfur kuma ana iya hana hazo samfurin da madaidaicin sa.
1. Lokacin ƙara acid, yawan zafin jiki na ƙara acid ya kamata a sarrafa shi sosai, gabaɗaya ≤20 ° C.
2. Ya kamata a sarrafa ƙwayar acid a 8-20%, ƙananan mafi kyau.
3. Ƙarin acid yana ɗaukar hanyar spraying, kuma an ƙara shi tare da tangential shugabanci na ganga rabo, kullum 1-3 minti.
4. Slurry gudun n=1400-2400r/m
(3)Mai Girma
1. Manufar emulsification
Homogeneous, ruwa mai ɗauke da kitse, CMC yakamata a haɗa shi da emulsifier, kamar monoglyceride, matsa lamba na homogenization shine 18-25mpa, kuma zafin jiki shine 60-70 ° C.
2. Manufa ta raba gari
Homogenization, idan daban-daban sinadaran a farkon mataki ba gaba daya daidai ba, har yanzu akwai wasu kananan barbashi, dole ne a yi kama, da homogenization matsa lamba ne 10mpa, da kuma zazzabi ne 60-70 ° C.
(4) Haihuwa
CMC a babban zafin jiki, musamman lokacin da zafin jiki ya fi 50 ° C na dogon lokaci, danko na CMC tare da ƙarancin inganci zai ragu ba tare da jurewa ba. Dankowar CMC na masana'antun gabaɗaya zai ragu da gaske a 80 ° C na mintuna 30, don haka ana iya amfani da haifuwa nan take ko barization. Hanyar haifuwa don rage lokacin CMC a babban zafin jiki.
(5) Sauran kiyayewa
1. Ruwan da aka zaɓa ya kamata ya zama mai tsabta da kuma kula da ruwan famfo kamar yadda zai yiwu. Bai kamata a yi amfani da ruwa mai kyau don guje wa kamuwa da ƙwayoyin cuta ba kuma ya shafi ingancin samfur.
2. Ba za a iya amfani da kayan aiki don narkar da da adana CMC a cikin kwantena na karfe ba, amma ana iya amfani da kwantena na bakin karfe, kwandon katako, ko kwantena na yumbu. Hana kutsawa na ion ƙarfe divalent.
3. Bayan kowane amfani da CMC, ya kamata a daure bakin buhun buhun don hana sha danshi da tabarbarewar CMC.
03 Amsoshin tambayoyi a cikin amfani da CMC
Ta yaya aka bambanta ƙananan danko, matsakaici-danko, da babban dankowa a tsari? Shin za a sami bambanci cikin daidaito?
Amsa:
An fahimci cewa tsawon sarkar kwayoyin halitta daban ne, ko kuma nauyin kwayar halitta ya bambanta, kuma an raba shi zuwa ƙananan, matsakaici da babba. Tabbas, aikin macroscopic yayi daidai da danko daban-daban. Irin wannan taro yana da danko daban-daban, kwanciyar hankali samfurin da rabon acid. Dangantakar kai tsaye ya dogara ne akan maganin samfurin.
Menene takamaiman wasan kwaikwayon na samfuran tare da matakin maye gurbin sama da 1.15? A wasu kalmomi, mafi girman matakin maye gurbin, an inganta takamaiman aikin samfurin?
Amsa:
Samfurin yana da babban matsayi na musanya, ƙara yawan ruwa, da rage girman pseudoplasticity. Kayayyakin da ke da ɗanko iri ɗaya suna da babban matsayi na musanya da kuma fitacciyar ji mai santsi. Kayayyakin da ke da babban matsayi na maye gurbin suna da bayani mai haske, yayin da samfuran da ke da babban matsayi na maye gurbin suna da bayani mai farar fata.
Shin yana da kyau a zaɓi matsakaicin danko don yin abin sha mai ƙima?
Amsa:
Matsakaici da ƙananan samfuran danko, matakin maye gurbin shine kusan 0.90, kuma samfuran tare da mafi kyawun juriya na acid.
Ta yaya CMC zai narke da sauri? Wani lokaci, bayan tafasa, yana narkewa a hankali.
Amsa:
Mix da sauran colloids, ko tarwatsa da 1000-1200 rpm agitator.
Dispersibility na CMC ba shi da kyau, hydrophilicity yana da kyau, kuma yana da sauƙi don tari, kuma samfurori tare da babban digiri na maye gurbin sun fi bayyane! Ruwan dumi yana narkewa da sauri fiye da ruwan sanyi. Ba a ba da shawarar tafasa gabaɗaya. dafa abinci na dogon lokaci na samfuran CMC zai lalata tsarin kwayoyin halitta kuma samfurin zai rasa danko!
