Tlhaloso ea Lihlahisoa
Carrageenan ke semi refined food grade Kappa Karrageenan (E407a) e nkiloeng ho Eucheuma cottonii seaweeds. E etsa li-gel tse thermoreversible ka mahloriso a lekaneng 'me e na le kutloelo-bohloko haholo ho ion ea potasiamo e ntlafatsang haholo thepa ea eona ea gelling. Carrageenan e tsitsitse sebakeng sa alkaline. Carrageenan ke lelapa le hlahang ka tlhaho la lik'habohaedreite tse ntšitsoeng maoatleng a leoatle a khubelu. Carrageenan e ntšoa ka metsi tlas'a maemo a sa jeleng paate kapa a alkaline mocheso o phahameng. Carrageenan e hloekisitsoeng e fumanoa tharollong ka ho noa joala kapa potassium gelation.
Semi-refined carrageenan e hlatsuoa 'me e sebelisoa alkaline ea leoatleng. Carrageenan ha e ntšoe ka metsing a leoatle empa e ntse e le ka har'a matrix ea lerako la sele. Lihlahisoa tsa khoebo tsa carrageenan hangata li tloaeleha bakeng sa ho fumana thepa e nepahetseng ea gelling le thickening. Ka ho sebelisa sehlahisoa se loketseng sa carrageenan, moetsi oa lihlahisoa a ka etsa litlolo ho tloha ho metsi a sa lefelloeng ho ea ho li-gel tse tiileng. Ntle le ho fana ka mefuta e tloaelehileng, COLORCOM e sebetsa 'moho le bareki ho hlahisa lihlahisoa tse ncha le mekhoa ea likopo tse khethehileng.
Li-carrageenan ke limolek'hule tse kholo, tse tenyetsehang haholo tse kobehang ho etsa libopeho tsa helical. Sena se ba fa bokhoni ba ho etsa mefuta e fapaneng ea li-gel ka mocheso oa kamore. Li sebelisoa haholo liindastering tsa lijo le tse ling e le li-agent tse teteaneng le tse matlafatsang. Molemo o khethehileng ke hore ke pseudoplastic-ba tšesaane tlas'a khatello ea ho kuta 'me ba tsosolosa viscosity ea bona hang ha khatello ea kelello e tlosoa. Sena se bolela hore li bonolo ho li pompa, empa li satalla hape ka mor'a moo.
Li-carrageenans kaofela li na le li-polysaccharides tse boima ba molek'hule tse entsoeng ka likarolo tse pheta-phetoang tsa galactose le 3,6 anhydrogalactose (3,6-AG), tse nang le sulfated le tse sa hloekisoang. Liyuniti li kopantsoe ka ho fapanyetsana lihokelo tsa alpha 1–3 le beta 1–4 glycosidic.
Ho na le lihlopha tse tharo tse kholo tsa khoebo tsa carrageenan:
Kappa e etsa li-gel tse matla, tse thata ka pel'a li-ion tsa potassium; e sebetsana le Liprotheine tsa lebese. E fumanoa haholo-holo ho tsoa Kappaphycus alvarezii[3].Iota e etsa li-gel tse bonolo boteng ba li-ion tsa calcium. E hlahiswa haholo-holo ho tswa ho Eucheuma denticulatum.Lambda ha e gel, mme e sebelisetsoa ho tenya lihlahisoa tsa lebese. Mohloli o tloaelehileng ka ho fetisisa ke Gigartina ho tloha Amerika Boroa. Liphapang tse ka sehloohong tse susumetsang thepa ea kappa, iota, le lambda carrageenan ke palo le boemo ba lihlopha tsa ester sulfate ho lihlopha tse pheta-phetoang tsa galactose. Maemo a phahameng a ester sulfate a theola mocheso oa ho qhibiliha ha carrageenan le ho hlahisa li-gel tse matla tse fokolang, kapa ho kenya letsoho ho thibelang gel (lambda carrageenan).
Mefuta e mengata e khubelu ea algal e hlahisa mefuta e fapaneng ea li-carrageenans nakong ea histori ea tsoelo-pele ea tsona. Mohlala, mofuta oa Gigartina o hlahisa haholo-holo kappa carrageenans nakong ea papali ea eona ea gametophytic, le lambda carrageenans nakong ea eona ea sporophytic. Sheba Phapanyetsano ea meloko.
Tsohle li qhibiliha metsing a chesang, empa, metsing a batang, ke mofuta oa lambda feela (le letsoai la sodium la tse ling tse peli) tse qhibilihang.
Ha e sebelisoa lihlahisoa tsa lijo, carrageenan e na le E-number E407 kapa E407a ea EU ha e le "processed eucheuma seaweed", 'me hangata e sebelisoa e le emulsifier.
Likarolong tse ling tsa Scotland (moo e tsejoang e le (An) Cairgean ka Scottish Gaelic) le Ireland (mefuta e fapaneng e sebelisoang ke Chondrus Crispus e tsejoang ka Segaeli sa Ireland ka mefuta e fapaneng e le carraigín [lefika le lenyenyane], fiadháin [lintho tse hlaha], clúimhín cait [katse's puff] , mathair an duilisg [mother of seaweeds], ceann donn [red head]), e tsejwa e le Carrageen Moss e bediswa ka lebese mme e sefshoe, pele ho kenngwa tswekere le ditlolo tse ding tse kang vanilla, sinamone, brandy, kapa whiskey. Sehlahisoa sa ho qetela ke mofuta oa jelly e tšoanang le pannacotta, tapioca, kapa blancmange.
Ha iota carrageenan e kopantsoe le sodium stearoyl lactylate (SSL), ho thehoa phello ea synergistic, e lumellang ho tsitsisa le ho etsa emulsifying e sa fumanoeng ka mofuta ofe kapa ofe oa carrageenan (kappa/lambda) kapa ka li-emulsifiers tse ling (mono le diglycerides, joalo-joalo). SSL e kopantsoe le iota carrageenan, e khona ho hlahisa li-emulsion tlas'a maemo a chesang le a batang ka ho sebelisa mafura a meroho kapa a liphoofolo.
United States, carrageenan ke motsoako oa lebese la soya le rekisoang tlas'a mofuta oa Whole Foods.
