Carrageenan - kuyini? Yimuphi umonakalo enza isimame carrageenan

Ukudla izithasiselo (stabilizers) kabanzi yobisi, ukudla okunoshukela inyama, ebhikawozi umkhakha. Siyabonga ukusetshenziswa kwabo imikhiqizo ngesikhathi ofiselekayo ukwakheka, ukuthamba nokuthi siqine kangakanani. Muva nje, ngo-kabanzi njengendlela carrageenan isimame. Kuyini lokhu? Kulesi sihloko sizosebenza le nkinga.

Carrageenan etholwe ngenxa ukucutshungulwa zasolwandle obomvu ulwelwe Rhodophyceae umndeni. Lezi ulwelwe etshalwa cishe wonke amanzi eMhlabeni. ulwelwe Red - izitshalo ukushisa-onothando, ngakho, njengoba umthetho, bona kungabonwa ogwini Indonesia, France, eChile, e-USA kanye nase-Canada.

IStabilizer carrageenan - engokwemvelo gelling ejenti, thickener. Lokhu ibhekwa njengengxenye yokudla okunempilo is kabanzi womshini imikhiqizo yobisi, ukudla okunoshukela isoseji nemikhiqizo izinhlanzi. Ngaphandle carrageenan kuqedile nokukhiqizwa kwezincwadi ice cream, ngoba sibonga ukungaguquguquki yayo alube ibangelwa ukusetshenziswa umkhiqizo wokugcina.

Carrageenan: Uhlolojikelele

Carrageenan wavulwa ngasekupheleni kwekhulu le-19, kodwa kuze kube manje lokhu ketshezi kuyinto njengoba ucwaningo futhi isithakazelo ezingokoqobo ukuze ososayensi abaningi emhlabeni. Amabhizinisi kuqala ukucutshungulwa yezimboni carrageenan uvele e-United States phakathi nawo-30 yalolucwaningo ka XX leminyaka. Okwamanje, kunezinhlobo ezingaphezu kuka-3 ayizinkulungwane izinhlobo carrageenan, futhi lokhu akulona sibalo sokugcina. Minyaka yonke, abacwaningi bathole izinhlobo ezintsha zezinto carrageenan. Kusukela manje, niyazi, uma wavulwa carrageenan, kuyini, futhi yini izindawo isetshenziswa.

Nakuba lokuqoqa isigaba begazi ukukhula, kanye ukujula Locus ulwelwe obomvu kuthinte izakhiwo physico-amakhemikhali carrageenan. Ngenxa ngokucubungula zobuchwepheshe ulwelwe etholwe carrageenans amafraktjhini eziningana, okuyinto zingafani chemical yabo ukwakheka, kanye nezinye izinkomba izinga. Ngalesi sikhathi, kukhona ezintathu amakilasi carrageenan, zehlukene degree of sulphation: kappa, iota futhi lambda carrageenans.

Kappa-carrageenan, Kuyini lokhu?

Lesi sigaba carrageenans okubonakala kalula oncibilikayo emanzini ashisayo. Ngemva nokonakala kanye nokupholisa okwalandela, akha gel ngamandla okusezingeni eliphezulu jelly. Gel ekilasini kappa kuhle bayacasuka ubisi amaprotheni. Phakathi womshini imikhiqizo inyama njengoba okufakiwe ukudla esetshenziswayo kappa-carrageenan. Isicelo efana ngenxa ikhono ukwandisa viscosity uketshezi futhi isenzo njengoba thickener, hhayi kuphela, kodwa futhi emulsifier.

izinhlobo carrageenan

Ngu degree of ukuhlanzwa carrageenans kungenziwa labizwa ngokuthi semi elicwengiweyo futhi inobuntu obuhle. Umphumela wokuqala etholwe zasolwandle abilayo isixazululo ane-alikhali. Ngemva kwalokho, zinhlayiya kuhlungwa carrageenans, kanzulu asuswe isixazululo. Le ndlela kuyinto kunalokho isikhathi esiningi futhi kuyabiza. Ngokuvamile obusetshenziswa embonini carrageenan semi acwengekile. Lolu hlobo ulwelwe is etholwe abilayo isixazululo potassium hydroxide. Potassium kuvimbela hydrolysis ka carrageenan ikhambi, kodwa ivumela chaza carbohydrate namaprotheni ulwelwe. Ngemva zokukhwabanisa idatha yesixazululo zasolwandle isuswe, wageza.

Iota, futhi lambda-carrageenan, Kuyini lokhu?

Iota-carrageenan yakha gel buthaka kuqhathaniswa kappa-ijeli. Kuyaphawuleka ukuthi si abanjalo bangabaphostoli nokunwebeka ngaphezulu, bayakwazi ukubuyisela isakhiwo yayo yasekuqaleni ngisho nangemva negalelo lokukhanda. Kule ndaba, iota-carrageenan ngokuvamile lisetshenziswa njengendlela isimame ukumiswa. Ngaphandle jellies ethulwa ngenhla esitebeleni ngokwanele ngesikhathi imijikelezo ezilandelanayo okokuqandisa / incibilikiswa.

Lambda-carrageenan ingeyona si ngoba ihlanganisa eziningi sulfo-amaqembu, kodwa izixazululo ezinjalo abe okusezingeni eliphezulu viscosity. Ngakho-ke, le ngxenyana yesakhi segazi ilungele kumiswa emulsions, foams futhi ukumiswa.

Ukusebenzisa carrageenan ukudla okufakiwe

Kukhona ulwazi ukuthi carrageenan ukudla isimame iphephile impilo yethu, ngaphezu, it has eziningi izakhiwo ezuzisayo esiyingqayizivele. Ochwepheshe abaningi banomuzwa ukuthi inzuzo eyinhloko ngokusebenzisa yalolu ketshezi - elihlanza umzimba womuntu kusuka ukungcola ezinobuthi futhi chemical biosoedineny, kuhlanganise izinsimbi ezisindayo. Ngaphezu kwalokho, kungase kutholakale ukuthi carrageenans kungukuthi nomzimba abonise namagciwane, anticoagulant, anti-amagciwane anti-enobuthi umphumela.

Carrageenan: umonakalo

lososayensi iye yafakazela ukuthi carrageenan okonakele kungase kubangele ukuthuthukiswa izifo yaleli pheshana emathunjini, kanye nomdlavuza. Kuyini carrageenan esiyingozi? It ilimaza okufakiwe kungase kuhlotshaniswe yokuthi into eziphila abakhuthele avuse ukuthuthukiswa ukusabela ukuvuvukala emzimbeni. Carrageenan ngesikhathi hydrolysis esiswini kudedela ezinobuthi, okuyizinto ngesisekelo izifo ezingaphezu kwekhulu. Phakathi kwabo, kolwelwesi, enteritis, nesifo, samathambo, isifo sokuqina kwemithambo yegazi, nokunye. D. okonakele carrageenan kuyinto eyingozi empilweni zethu, ngakho-ke kuvame kutsi kufakwe ukudla.

Muva nje, abameleli UBANI uncoma kakhulu ukusetshenziswa izithasiselo in imikhiqizo, okuyinto zenzelwe umsoco of izingane nabesifazane abakhulelwe. Ucwaningo lwamuva yokulinga ososayensi American olwenziwe izilwane zokucwaninga luye lwabonisa ukuthi poliginan (ingxenye carrageenan molecule) kungabangela izilonda futhi wokugaya ukudla umdlavuza ipheshana. wathi ukudla isimame ngesisekelo imininingwane abayithole akuyona siwela isigaba kungavunyelwe Izithako zokudla, kodwa imbangela pathologies eziningi kungaba basakhonza, ngakho yidla ukudla okune carrageenan (ukudla okufakiwe E-407 kanye no-E-407a) kufanele kube ngokuqapha. Naphezu ubuthi efakazelwe, isimame E-407 ovunyelwe ukusebenzisa indawo yakwa-iningi uthi, kuhlanganise Russian Federation. Nokho, isinqumo ngesakho, abangane bami.
