Sodium carboxymethyl cellulose, yotchedwa carboxymethyl cellulose (CMC) ndi mtundu wa ether ya polymer fiber ether yokonzedwa ndi kusinthidwa kwa mankhwala a cellulose achilengedwe.Kapangidwe kake ndi kagawo kakang'ono ka D-glucose kudzera mu β (1 → 4) glycosidic chomangira cholumikizidwa zigawo.Kugwiritsa ntchito CMC kuli ndi zabwino zambiri kuposa zowonjezera zakudya zina.
01 CMC imagwiritsidwa ntchito kwambiri muzakudya
(1) CMC ili ndi bata labwino
Muzakudya zozizira monga popsicles ndi ayisikilimu, zimatha kuwongolera mapangidwe a ayezi, kuonjezera kuchuluka kwa kufalikira ndi kusunga mawonekedwe a yunifolomu, kukana kusungunuka, kukhala ndi kukoma kwabwino komanso kosalala, ndikuyera mtundu.
Mu mkaka, kaya ndi mkaka wokometsera, mkaka wa zipatso kapena yoghurt, amatha kuchitapo kanthu ndi mapuloteni mkati mwa isoelectric point ya pH value (PH4.6) kuti apange zovuta ndi zovuta, zomwe zimapindulitsa kukhazikika kwa emulsion ndi Kupititsa patsogolo kukana kwa mapuloteni.
(2) CMC ikhoza kuphatikizidwa ndi ma stabilizers ena ndi emulsifiers
Muzakudya ndi zakumwa, opanga ambiri amagwiritsa ntchito mitundu yosiyanasiyana ya stabilizers, monga: xanthan chingamu, guar chingamu, carrageenan, dextrin, ndi zina zotero. Emulsifiers monga: glycerol monostearate, sucrose fatty acid esters, etc., amaphatikizidwa kuti agwirizane zabwino ndikuchita nawo mgwirizano kuti achepetse ndalama zopangira.
(3) CMC ili ndi pseudoplasticity
The mamasukidwe akayendedwe a CMC ndi zosinthika pa kutentha osiyana.Pamene kutentha kumakwera, kukhuthala kwa yankho kumachepa, ndipo mosiyana;pamene mphamvu yometa ubweya ilipo, kukhuthala kwa CMC kudzachepa, ndipo ndi kuwonjezeka kwa mphamvu yometa ubweya, kukhuthala kudzachepa.Zinthu izi zimathandiza CMC kuchepetsa zida katundu ndi kusintha homogenization Mwachangu pamene oyambitsa, homogenizing, ndi mayendedwe payipi, amene ndi wosayerekezeka ndi stabilizers ena.
02 Zofunikira za ndondomeko
Monga chokhazikika chokhazikika, CMC idzakhudza zotsatira zake ngati itagwiritsidwa ntchito molakwika, komanso imapangitsa kuti chinthucho chichotsedwe.Chifukwa chake, kwa CMC, ndikofunikira kufalitsa mokwanira komanso moyenera yankho kuti liwongolere bwino, kuchepetsa mlingo, kuwongolera mtundu wazinthu ndikuwonjezera zokolola.Makamaka, chidwi chiyenera kuperekedwa pa gawo lililonse la ndondomekoyi:
(1) Zosakaniza
1. High-liwiro kukameta ubweya njira kubalalitsidwa ndi makina mphamvu
Zida zonse zokhala ndi luso losanganikirana zitha kugwiritsidwa ntchito kuthandiza CMC kumwazikana m'madzi.Kupyolera mu kumeta kothamanga kwambiri, CMC ikhoza kumizidwa mofanana m'madzi kuti ifulumizitse kusungunuka kwa CMC.
Opanga ena pakali pano amagwiritsa ntchito zosakaniza za ufa wa madzi kapena akasinja osakaniza othamanga kwambiri.
2. Njira yosakaniza yosakaniza yowuma shuga
Sakanizani bwino ndi CMC ndi shuga granulated pa chiŵerengero cha 1:5, ndi kuwaza izo pang'onopang'ono pansi oyambitsa zonse kupasuka kwathunthu CMC.
3. Sungunulani m'madzi odzaza shuga
Monga caramel, etc., akhoza imathandizira kutha kwa CMC.
(2) Kuonjezera asidi
Kwa zakumwa zina za acidic, monga yogurt, zinthu zosagwira asidi ziyenera kusankhidwa.Ngati agwiritsidwa ntchito moyenera, mtundu wazinthu ukhoza kuwongolera komanso kugwa kwa zinthu komanso kusanja kungapewedwe.
1. Powonjezera asidi, kutentha kwa asidi kuwonjezera kuyenera kuyendetsedwa mosamalitsa, kawirikawiri ≤20°C.
2. Kuchuluka kwa asidi kuyenera kuyendetsedwa pa 8-20%, kutsika bwino.
3. Acid kuwonjezera utenga kupopera mbewu mankhwalawa njira, ndipo iwonjezedwa motsatira tangential malangizo chidebe chiŵerengero, nthawi zambiri 1-3 mphindi.
4. Liwiro lothamanga n=1400-2400r/m
(3) Zofanana
1. Cholinga cha emulsification
Zakudya zamadzimadzi zokhala ndi mafuta, CMC ziyenera kuphatikizidwa ndi emulsifier, monga monoglyceride, kuthamanga kwa homogenization ndi 18-25mpa, ndi kutentha ndi 60-70 ° C.
2. Cholinga chogawa madera
Homogenization, ngati zosakaniza zosiyanasiyana mu siteji oyambirira si kwathunthu yunifolomu, akadali ena particles ang'onoang'ono, ayenera homogenized, kuthamanga homogenization ndi 10mpa, ndi kutentha ndi 60-70 ° C.
(4) Kulera
CMC pa kutentha kwambiri, makamaka pamene kutentha ndi apamwamba kuposa 50 ° C kwa nthawi yaitali, ndi mamasukidwe akayendedwe a CMC ndi khalidwe osauka adzachepa osasinthika.Kukhuthala kwa CMC kwa opanga ambiri kumatsika kwambiri pa 80 ° C kwa mphindi 30, kotero kutsekereza pompopompo kapena barization kungagwiritsidwe ntchito.Njira yotsekereza kufupikitsa nthawi ya CMC pa kutentha kwakukulu.
(5) Njira zina zodzitetezera
1. Madzi osankhidwa ayenera kukhala oyera komanso oyeretsedwa ndi madzi apampopi momwe angathere.Madzi abwino sayenera kugwiritsidwa ntchito kupewa matenda tizilombo ndi kukhudza khalidwe mankhwala.
2. Ziwiya zosungunulira ndi kusunga CMC sizingagwiritsidwe ntchito m'mitsuko yachitsulo, koma zitsulo zosapanga dzimbiri, mabeseni amatabwa, kapena zotengera zadothi zitha kugwiritsidwa ntchito.Pewani kulowetsedwa kwa ayoni achitsulo a divalent.
3. Pambuyo pa kugwiritsa ntchito CMC kulikonse, pakamwa pa thumba loyikamo payenera kumangiriridwa mwamphamvu kuti musamayamwidwe ndi chinyezi komanso kuwonongeka kwa CMC.
03 Mayankho a mafunso pogwiritsa ntchito CMC
Kodi kukhuthala kwapakati, mamasukidwe apakati, ndi makulidwe apamwamba amasiyanitsidwa bwanji?Kodi padzakhala kusiyana kofanana?
Yankhani:
Zimamveka kuti kutalika kwa unyolo wa maselo ndi kosiyana, kapena kulemera kwa maselo ndi kosiyana, ndipo kumagawidwa kukhala otsika, apakati komanso apamwamba kwambiri.Zachidziwikire, mawonekedwe a macroscopic amafanana ndi kukhuthala kosiyana.ndende yemweyo ali osiyana mamasukidwe akayendedwe, mankhwala bata ndi asidi chiŵerengero.Ubale wachindunji makamaka umadalira yankho la mankhwala.
Ndi machitidwe otani azinthu zomwe zili ndi digiri yakusintha pamwamba pa 1.15?M'mawu ena, kuchuluka kwa kulowetsa m'malo kumakwera, magwiridwe antchito ake awonjezeka?
Yankhani:
Chogulitsacho chimakhala ndi kuchuluka kwa m'malo, kuchuluka kwamadzimadzi, ndikuchepetsa kwambiri pseudoplasticity.Zogulitsa zomwe zili ndi mamasukidwe omwewo zimakhala ndi malo apamwamba komanso zowoneka bwino zoterera.Zogulitsa zomwe zili ndi kuchuluka kwakukulu kolowa m'malo zimakhala ndi yankho lonyezimira, pomwe zinthu zomwe zimakhala ndi m'malo mwake zimakhala ndi yankho loyera.
Kodi ndikwabwino kusankha mamasukidwe apakati kuti mupange zakumwa zama protein zotupitsa?
Yankhani:
Zapakatikati ndi otsika mamasukidwe akayendedwe mankhwala mlingo wa m'malo ndi za 0,90, ndi mankhwala ndi bwino asidi kukana.
Kodi CMC ingasungunuke bwanji mwachangu?Nthawi zina, itatha kuwira, imasungunuka pang'onopang'ono.
Yankhani:
Sakanizani ndi ma colloid ena, kapena mubalalitseni ndi 1000-1200 rpm agitator.
Kufalikira kwa CMC sikwabwino, hydrophilicity ndiyabwino, ndipo ndiyosavuta kuphatikizira, ndipo zinthu zomwe zili ndi digiri yapamwamba yolowa m'malo ndizodziwikiratu!Madzi ofunda amasungunuka mofulumira kuposa madzi ozizira.Kuwira sikovomerezeka.Kuphika kwanthawi yayitali kwa zinthu za CMC kumawononga mawonekedwe a maselo ndipo chinthucho chidzataya kukhuthala kwake!
