IiNkcazo zeeMveliso
ICarrageenan libakala lokutya elisulungekileyo i-Kappa Karrageenan (E407a) elikhutshwe kwi-Eucheuma cottonii seaweeds.Yenza iijeli ezitshisayo kwi-concentration eyaneleyo kwaye inomdla kakhulu kwi-ion ye-potassium eyandisa kakhulu iimpawu zayo ze-gelling.ICarrageenan izinzile kwi-alkali medium.I-Carrageenan yintsapho eyenzeka ngokwemvelo ye-carbohydrates ekhutshwe kwi-red seaweed.I-carrageenan ecociweyo ifunyanwa ikakhulu kwisisombululo ngokusiwa kotywala okanye i-potassium gelation.
I-Semi-refined carrageenan iyahlanjwa kwaye iphathwe ngealkali yolwandle.I-carrageenan ayikhutshwa kwi-seaweed kodwa isagcinwe kwi-matrix yodonga lweseli.Iimveliso zorhwebo ze-carrageenan zihlala zisemgangathweni ukufumana i-gelling efanelekileyo kunye neempawu zokuqina.Ngokusebenzisa imveliso efanelekileyo ye-carrageenan, i-formulator inokudala i-textures ukusuka kwi-liquid-free-flowing liquids ukuya kwii-gels eziqinileyo.Ukongeza kokunikezela ngeentlobo eziqhelekileyo, i-COLORCOM isebenza ngokubambisana nabathengi ukuphuhlisa iimveliso ezintsha kunye nokuqulunqwa kwezicelo ezithile.
IiCarrageenans zinkulu, iimolekyuli ezibhetyebhetye kakhulu ezijija zenza i-helical structures.Oku kubanika amandla okwenza iintlobo ezahlukeneyo zeegels kwiqondo lokushisa.Zisetyenziswa ngokubanzi ekutyeni nakwamanye amashishini njengezinto ezityebisayo kunye nokuzinzisa.Inzuzo ethile kukuba i-pseudoplastic-bancinci phantsi koxinzelelo lwe-chear kwaye baphinde babuyisele i-viscosity yabo xa uxinzelelo lususiwe.Oku kuthetha ukuba kulula ukupompa, kodwa ukuqina kwakhona emva koko.
Zonke ii-carrageenans zi-polysaccharides eziphezulu ze-molecular-weight-weight ezenziwe ngokuphindaphindiweyo kweeyunithi ze-galactose kunye ne-3,6 anhydrogalactose (3,6-AG), zombini i-sulfated kunye ne-nonsulfated.Iiyunithi zidityaniswa ngokutshintshana kwe-alpha 1-3 kunye ne-beta 1-4 i-glycosidic linkages.
Kukho iiklasi ezintathu eziphambili zorhwebo ze-carrageenan:
I-Kappa yenza iigels ezinamandla, eziqinileyo phambi kwee-ion ze-potassium;idibana neeProteins zobisi.Ifumaneka ikakhulu kwi-Kappaphycus alvarezii[3] .Iota yenza iigels ezithambileyo kubukho be-calcium ion.Iveliswa ikakhulu kwi-Eucheuma denticulatum.Lambda ayifaki ijeli, kwaye isetyenziselwa ukujiya iimveliso zobisi.Umthombo oqhelekileyo nguGigartina waseMzantsi Melika.Ukwahlukana okuphambili okuchaphazela iimpawu ze-kappa, iota, kunye ne-lambda carrageenan yinombolo kunye nesikhundla samaqela e-ester sulfate kwiiyunithi eziphindaphindiweyo zegalactose.Amanqanaba aphezulu e-ester sulfate anciphisa ukushisa kwe-solubility ye-carrageenan kwaye avelise iigels zamandla aphantsi, okanye abe negalelo kwi-gel inhibition (lambda carrageenan).
Iintlobo ezininzi ze-algal ezibomvu zivelisa iintlobo ezahlukeneyo ze-carrageenans ngexesha lembali yophuhliso.Umzekelo, i-genus Gigartina ivelisa ikakhulu i-kappa carrageenans ngexesha le-gametophytic, kunye ne-lambda carrageenans ngexesha le-sporophytic.Jonga Ukutshintshana kwezizukulwana.
Zonke zinyibilika emanzini ashushu, kodwa, emanzini abandayo, kuphela ifom ye-lambda (kunye neetyuwa zesodium zezinye ezimbini) ezinyibilikayo.
Xa isetyenziswe kwimveliso yokutya, i-carrageenan ine-EU yokongeza i-E-number E407 okanye i-E407a xa ikhona njenge "processed eucheuma seaweed", kwaye isetyenziswa ngokuqhelekileyo njenge-emulsifier.
Kwiindawo zaseSkotlani (apho yaziwa ngokuba yi (An) Cairgean ngesiScottish Gaelic) naseIreland (uhlobo olusetyenziswayo yiChondrus Crispus eyaziwa ngesiIrish Gaelic ngokwahlukeneyo njenge carraigín [ilitye elincinane], fiadháin [izinto zasendle], clúimhín cait [cat's puff] , mathair an duilisg [mother of seaweeds], ceann donn [red head]), yaziwa njenge Carrageen Moss ibiliswa ngobisi kwaye ihluziwe, phambi kokuba kugalelwe iswekile nezinye iziqholo ezifana ne vanilla, cinnamon, brandy, okanye iwhisky.Ukuphela kwemveliso luhlobo lwejeli efana ne-pannacotta, tapioca, okanye i-blancmange.
Xa i-iota carrageenan idibene ne-sodium stearoyl lactylate (SSL), isiphumo se-synergistic sidalwa, sivumela ukuzinza kunye ne-emulsifying engafunyanwanga naluphi na uhlobo lwe-carrageenan (i-kappa / lambda) okanye kunye nezinye i-emulsifiers (i-mono kunye ne-diglycerides, njl.).I-SSL idityaniswe ne-iota carrageenan, iyakwazi ukuvelisa i-emulsions phantsi kweemeko ezishushu kunye nezibandayo usebenzisa imifuno okanye isilwanyana.
EUnited States, i-carrageenan sisithako sobisi lwesoya oluthengiswa phantsi kohlobo lwe-Whole Foods.
