Iko kushandiswa kweCMC kune akawanda mabhenefiti pamusoro pezvimwe zvinokora zvekudya:
1. CMC inoshandiswa zvakanyanya mukudya uye maitiro ayo
(1) CMC ine kugadzikana kwakanaka
Muzvokudya zvinotonhora zvakadai sepopsicles uye ice cream, kushandiswa kweCMCinogona kudzora kuumbwa kwemakristasi echando, kuwedzera chiyero chekuwedzera uye kuchengetedza chimiro chakafanana, kuramba kunyunguduka, kuve nekuravira kwakanaka uye kwakatsetseka, uye kuchena ruvara. Muzvigadzirwa zvemukaka, ingave mukaka wakarungwa, mukaka wemichero kana yoghurt, inogona kuita neprotein mukati meiyo isoelectric point ye pH kukosha (PH4.6) kugadzira yakaoma ine chimiro chakaomarara, chinobatsira kugadzikana kwe emulsion uye kuvandudza mapuroteni kuramba.
(2) CMC inogona kusanganiswa nemamwe ma stabilizer uye emulsifiers.
Muzvokudya uye zvinwiwa zvigadzirwa, vashandi vakawanda vanoshandisa zvakasiyana-siyana zvinogadzirisa, zvakadai se: xanthan gum, guar gum, carrageenan, dextrin, nezvimwewo, uye emulsifiers yakadai se: glyceryl monostearate, sucrose fatty acid ester, nezvimwewo. Mabhenefiti ekuwedzera anogona kuwanikwa, uye synergistic mhedzisiro inogona kuwanikwa kudzikisa mutengo wekugadzira.
(3) CMC ndeye pseudoplastic
Iyo viscosity yeCMC inodzoserwa pane tembiricha dzakasiyana. Sezvo kutonhora kuchikwira, viscosity yemhinduro inoderera, uye zvakasiyana; kana simba rekugera riripo, viscosity yeCMC inoderera, uye sezvo simba rekugera rinowedzera, viscosity inova diki. Izvi zvivakwa zvinoita kuti CMC ideredze mutoro wemidziyo uye kuvandudza homogenization kushanda zvakanaka kana ichikurudzira, homogenizing, uye pombi yekufambisa, iyo isingaenzaniswi nemamwe anodzikamisa.
2. Process zvinodiwa
Sechigadziriso chinoshanda, CMC inokanganisa maitiro ayo kana ikashandiswa zvisina kunaka, uye kunyange kuita kuti chigadzirwa chiraswe. Naizvozvo, kune CMC, zvakakosha kwazvo kuparadzira zvakazara uye zvakaenzana mhinduro yekuvandudza kushanda kwayo, kuderedza dosi, kuvandudza chigadzirwa chemhando uye kuwedzera goho. Izvi zvinoda kuti mumwe nemumwe wevagadziri vedu vezvekudya anzwisise zvizere hunhu hweakasiyana mbishi uye kugadzirisa zvine hungwaru maitiro avo ekugadzira kuitira kuti CMC inyatso kutamba basa rayo, kunyanya mune yega yega nhanho inofanirwa kutarisisa kune:
(1) Zvisungo
1. Kushandisa mechanical high-speed shear dispersion method: Midziyo yese ine kugona kusanganisa inogona kushandiswa kubatsira CMC kupararira mumvura. Kuburikidza neshear yekumhanyisa, CMC inogona kunyikwa mumvura zvakaenzana kuti ikurumidze kuparara kweCMC. Vamwe vagadziri parizvino vanoshandisa masanganisi emvura-hupfu kana matangi ekusanganisa anomhanya.
2. Shuga yakaoma-kuvhenganisa nzira yekuparadzira: Sanganisa CMC neshuga pachiyero che1: 5, uye zvishoma nezvishoma umwase mukati pasi pekukurudzira nguva dzose kuti upedze zvakakwana CMC.
3. Kunyungudutswa nemvura ine shuga yakazara, yakadai secaramel, inogona kukurumidza kupera kweCMC.
(2) Acid kuwedzera
Kune zvimwe zvinwiwa zvine acidic, senge yogati, zvigadzirwa zvinodzivirira acid zvinofanirwa kusarudzwa. Kana akashandiswa zvakajairika, mhando yechigadzirwa inogona kuvandudzwa uye kunaya kwechigadzirwa uye stratification inogona kudzivirirwa.
1. Kana uchiwedzera asidhi, tembiricha yekuwedzera asidhi inofanira kudzorwa zvakasimba, kazhinji isingasviki 20°C.
2. Kugadziriswa kweasidhi kunofanira kudzorwa pa8-20%, iyo yakaderera iri nani.
3. Acid yekuwedzera inotora nzira yekupfapfaidza, uye inowedzerwa pamwe netangential gwara reiyo reshiyo yemidziyo, kazhinji 1-3min.
4. Slurry speed n = 1400-2400r / m
(3) Zvakafanana
1. Chinangwa che emulsification.
Homogenization: Pamvura yekudya ine mafuta, CMC inofanirwa kusanganiswa ne emulsifiers, senge monoglyceride, ine homogenization pressure ye18-25mpa uye tembiricha ye60-70 ° C.
2. Chinangwa cheDecentralized.
Homogenization. Kana izvo zvakasiyana-siyana zvinongedzo mukutanga nhanho zvisina kukwana zvakakwana, uye pachine zvimwe zvidiki zvidiki, zvinofanirwa kuve homogenized. Iyo homogenization pressure ndeye 10mpa uye tembiricha iri 60-70 ° C.
(4) Kuvharisa
Kana CMC ikaratidzwa kune tembiricha yakanyanya, kunyanya kana tembiricha yakakwira kupfuura 50 ° C kwenguva yakareba, viscosity yeCMC ine hutsika husina kunaka inodzikira zvisingadzoreki. Iyo viscosity yeCMC kubva kumugadziri wezvese inodonha zvakanyanya pakupisa kwe80 ° C kwemaminetsi makumi matatu. Sterilization nzira kupfupisa nguva CMC panguva tembiricha.
(5) Zvimwe zvokungwarira
1. Mvura yakasarudzwa inofanira kuva yakachena uye inogadziriswa mvura yepombi sezvinobvira. Mvura yakanaka haifanirwe kushandiswa kudzivirira hutachiona hwehutachiona uye hunokanganisa kunaka kwechigadzirwa.
2. Midziyo yekunyungudutsa nekuchengetedza CMC haigone kushandiswa mumidziyo yesimbi, asi midziyo yesimbi isina tsvina, mabheseni emapuranga, kana midziyo yeramic inogona kushandiswa. Kudzivirira kupinza kwe divalent metal ions.
3. Mushure mekushandiswa kwega kwega kweCMC, muromo webhegi rekurongedza unofanirwa kusungirirwa zvakasimba kudzivirira kunyura kwehunyoro uye kuparara kweCMC.
