Xanthan chingamu, inozivikanwawo seHanseum gum, imhando ye microbial exopolysaccharide inogadzirwa neXanthomnas campestris nekugadzira fermentation ichishandisa makabhohaidhiretsi sezvinhu zvikuru (zvakadai se corn starch). Ine rheology yakasiyana, inonyunguduka mumvura zvakanaka, kugadzikana kwekupisa uye acid-base, uye inoenderana zvakanaka nemunyu wakasiyana-siyana, se thickening agent, suspension agent, emulsifier, stabilizer, inogona kushandiswa zvakanyanya mukudya, petroleum, mishonga uye mamwe maindasitiri anopfuura makumi maviri, parizvino ndiyo yakakura kwazvo pasi rose kugadzirwa uye microbial polysaccharide inoshandiswa zvakanyanya.
Zvivakwa:Xanthan gum ine upfu hweyero kusvika kuchena, inonhuwa zvishoma. Inonyungudika mumvura inotonhora nekupisa, ine mhinduro isina kusimba, hainyungudike nechando kana kunyungudika, hainyungudike muethanol. Inopararira nemvura uye inosanganiswa kuita colloid yakasimba yehydrophilic viscous.
Kushandiswa：Nekuda kwe rheology yayo inoshamisa, kunyungudika kwayo mumvura, uye kugadzikana kwayo kwakanyanya mumamiriro ekupisa uye acid-base, xanthan gum yave chinhu chakakosha mukushandiswa kwakasiyana-siyana. Sechinhu chinosimbisa, chinomisa, chinogadzirisa, uye chinosimbisa, yakawana nzira yayo mumaindasitiri anopfuura makumi maviri, anosanganisira chikafu, peturu, mishonga, nezvimwe zvakawanda.
Indasitiri yezvekudya yave iri imwe yedzakanyanya kubatsirwa nehunyanzvi hwayo hunoshamisa hwe xanthan gum. Kugona kwayo kuwedzera magadzirirwo uye kugara kwenguva refu kwezvigadzirwa zvekudya kwakaita kuti ive sarudzo yakakurumbira pakati pevagadziri. Ingave iri mumasosi, madhirezi, kana zvinhu zvebhekari, xanthan gum inoita kuti muromo unzwe zvakanaka uye unoyevedza. Inoenderana nemunyu wakasiyana-siyana inobatsirawo pakugadzirwa kwayo kwechikafu.
Muindasitiri yepeturu, xanthan gum inoita basa rakakosha mukuchera nekupwanya mvura. Hunhu hwayo hwakasiyana hwe rheological hunoita kuti ive chinhu chakanaka chekuwedzera, ichivandudza kusimba kwemvura uye kugadzikana kwayo. Pamusoro pezvo, inoshanda senzira yekudzora kusefa, ichideredza kuumbwa kwemakeke efirita panguva yekuchera. Kugona kwayo kushanda mumamiriro ekupisa kwakanyanya uye kumanikidzwa kwakaita kuti ive sarudzo inofarirwa pakati pevashandi vemafuta.
Basa rekurapa rinobatsirwawo zvikuru nehunhu hwakanaka hwe xanthan gum. Maitiro ayo ekurapa anobvumira kuburitswa kwemishonga nenzira inodzorwa, zvichiita kuti ive chinhu chakakodzera mukugadzirwa kwemishonga. Uyezve, kugona kwayo kuenderana nehupenyu uye kuora kunoita kuti ive yakakodzera kushandiswa kwakasiyana-siyana kwekurapa senge maronda uye masisitimu ekutumira mishonga nenzira inodzorwa.
Kupfuura maindasitiri ataurwa pamusoro apa, xanthan gum inowanikwawo mune mamwe maindasitiri akawanda, kusanganisira indasitiri yemakemikari yezuva nezuva. Kubva pamazino kusvika kumashampoo, xanthan gum inobatsira pakuumbwa uye kugadzikana kwezvigadzirwa izvi.
Kubudirira kwe xanthan gum mukutengeserana hakuna muenzaniso kana tichienzanisa nedzimwe polysaccharides dzebhakitiriya. Mashandisirwo ayo akasiyana-siyana uye hunhu hwayo hwakasiyana zvakaita kuti ive chinhu chinoshandiswa nevagadziri vakawanda. Hapana imwe polysaccharide yebhakitiriya inogona kuenzana nekushanda kwayo kwakasiyana-siyana uye kushanda kwayo.

Kuchengetera:Xanthan chingamu inogona kushandiswa zvakanyanya mukubvisa mafuta, makemikari, chikafu, mishonga, kurima, madhayi, zvedongo, bepa, machira, zvizoro, kuvaka nekugadzira zvinoputika uye mamwe maindasitiri anopfuura makumi maviri mumhando dzezvigadzirwa dzinosvika zana. Kuti zvive nyore kuchengetedza nekutakura, inowanzogadzirwa kuita zvigadzirwa zvakaoma. Kuomesa kwayo kune nzira dzakasiyana dzekurapa: kuomesa ne vacuum, kuomesa nedhiramu, kuomesa ne spray, kuomesa ne fluidized bed uye kuomesa nemhepo. Nekuti chinhu chinonzwa kupisa, hachigone kutsungirira kurapwa nekupisa kwakanyanya kwenguva yakareba, saka kushandiswa kwe spray drying kuchaita kuti isanyungudike zvakanyanya. Kunyangwe kushanda kwekupisa kwekuomesa nedhiramu kwakanyanya, chimiro chemuchina chakaoma, uye zvakaoma kuita kuti ishandiswe mumaindasitiri makuru. Kuomesa ne fluidized bed spheres, nekuda kwekuwedzera kupisa nekutakurwa kwehuwandu uye kukuya nekupwanya, nguva yekuchengetedza zvinhu ipfupiwo, saka yakakodzera kuomesa zvinhu zvinopisa zvinonzwa kupisa senge xanthan gum.
Nzira dzekudzivirira pakushandisa:
1. Pakugadzirira xanthan gum solution, kana kupararira kwayo kusina kukwana, mavanga anoonekwa. Pamusoro pekukurunga zvizere, inogona kusanganiswa nezvimwe zvinhu, yozowedzerwa mumvura ichikurunga. Kana zvichiri kuoma kupararira, solvent inosanganiswa nemvura inogona kuwedzerwa, senge ethanol shoma.
2. Xanthan gum ianionic polysaccharide, inogona kushandiswa pamwe chete nezvimwe zvinhu zveanionic kana zvisiri zveionic, asi haigone kushanda nezvinhu zvecationic. Mhinduro yayo inoenderana zvakanaka uye yakagadzikana kune munyu mizhinji. Kuwedzera ma electrolytes akadai se sodium chloride ne potassium chloride kunogona kuvandudza viscosity uye kugadzikana kwayo. Calcium, magnesium nedzimwe bivalent salts dzakaratidza mhedzisiro yakafanana pa viscosity yavo. Kana huwandu hwemunyu hwakakwirira kupfuura 0.1%, viscosity yakakwana inosvikwa. Kuwanda kwemunyu kwakanyanya hakugadzirisi kugadzikana kwe xanthan gum solution, uye hakukanganisi rheology yayo, pH> chete Pa 10 o 'clock (zvigadzirwa zvekudya hazviwanzoonekwa), bivalent metal salts dzinoratidza katsika kekuumba ma gels. Pasi pemamiriro e acidic kana neutral, trivalent metal salts dzayo dzakadai sealuminium kana iron form gels. Kuwanda kwe monovalent metal salts kunodzivirira gelation.
3. Xanthan gum inogona kusanganiswa nezvimwe zvinhu zvinosimbisa ganda, zvakaita se cellulose derivatives, starch, pectin, dextrin, alginate, carrageenan, nezvimwewo. Kana ikasanganiswa negalactomannan, inobatsira pakuwedzera viscosity.
Mukupedzisa, xanthan gum inoshamisa yesainzi yemazuva ano. Kugona kwayo kwakasiyana semushonga wekukora, mushonga wekumisa, musanganiswa we emulsifier, uye mutsigiri kwakachinja mashandiro emaindasitiri akasiyana-siyana. Kubva pakudya kwatinodya kusvika kumishonga yatinovimba nayo, simba re xanthan gum harirambike. Kufarirwa kwayo mukutengeserana uye kushandiswa kwayo kwakakura kunoita kuti ive simba guru munyika yezvinhu zvinoshandiswa. Gamuchira mashiripiti e xanthan gum uye vhura kugona kwayo muzvigadzirwa zvako nhasi.
