Sharaxaada Alaabta
Carrageenan waa heerka cuntada la safeeyey ee Kappa Karrageenan (E407a) oo laga soo saaray geedaha badda ee Eucheuma cottonii. Waxay samaysaa jeel heerkul-ku-soo-noqosho leh oo ku filan feejignaan ku filan waxayna aad ugu nugul tahay ion-ka potassium-ka taasoo si weyn u wanaajisa sifooyinka gelling-ka. Carrageenan waxay ku xasilloon tahay dhexdhexaadka alkali. Carrageenan waa qoys si dabiici ah u dhaca oo ka kooban karbohaydraytyo laga soo saaray geedo badda cas Carrageenan la safeeyey ayaa inta badan laga soo kabsadaa xalka roobka alkohol ama gelation potassium.
Carrageenan sifaysan ayaa la dhaqaa waxaana lagu daaweeyaa alkali caleen badeed. Carrageenan lagama soo saaro geed-badeedka laakiin wali waxa uu ku jiraa matrixka gidaarka unugga. Badeecadaha carrageenan ee ganacsiga ayaa si joogta ah loo jaangooyay si loo helo dhogorta ugu fiican iyo guryaha dhumucdooda. Adigoo isticmaalaya badeecada carrageenan ee ku habboon, qaabeeyaha wuxuu abuuri karaa midabyo u dhexeeya dareeraha bilaashka ah ilaa jel adag. Marka lagu daro bixinta noocyada caadiga ah, COLORCOM waxay la shaqeysaa macaamiisha si ay u horumariyaan alaabooyin cusub iyo qaabab codsiyo gaar ah.
Carrageenans waa unugyo waaweyn, aadka u dabacsan oo laalaabaya samaynta qaab-dhismeedyo helical ah. Tani waxay siinaysaa awood ay ku sameeyaan noocyo kala duwan oo jel ah oo kala duwan heerkulka qolka. Waxaa si weyn loogu isticmaalaa cuntada iyo warshadaha kale sida wakiilada dhumuc iyo xasilinta. Faa'iidada gaarka ah ayaa ah inay yihiin pseudoplastic - waxay ku dhuuban yihiin diiqada xiirid waxayna ka soo kabtaan muuqooda marka walwalka laga saaro. Tani waxay ka dhigan tahay inay fududahay in la bamgareeyo, laakiin mar labaad way adkaadaan ka dib.
Dhammaan carrageenansku waa polysaccharides miisaankoodu sareeyo oo ka kooban unugyo galactose ah oo soo noqnoqda iyo 3,6 anhydrogalactose (3,6-AG), labadaba sulfated iyo kuwa aan lahayn. Unugyada waxaa ku biiraya beddelka alfa 1-3 iyo beta 1-4 glycosidic linkages.
Waxaa jira saddex nooc oo ganacsi oo waaweyn oo carrageenan ah:
Kappa waxay sameysaa jeel adag oo adag iyadoo ay jirto ions potassium; waxay la falgashaa Proteins-ka caanaha. Waxay inta badan ka soo baxdaa Kappaphycus alvarezii[3].Iota waxay samaysaa jeelyo jilicsan marka ay joogaan ion calcium. Waxa inta badan laga soo saaraa Eucheuma denticulatum.Lambda ma dhalaalayso, waxaana loo isticmaalaa in lagu dhuujiyo waxyaabaha caanaha laga sameeyo. Ilaha ugu caansan waa Gigartina oo ka timid Koonfurta Ameerika. Kala duwanaanshaha aasaasiga ah ee saameeya guryaha kappa, iota, iyo lambda carrageenan waa tirada iyo booska kooxaha ester sulfate ee unugyada galactose ee soo noqnoqda. Heerarka sare ee ester sulfate waxay hoos u dhigaan heerkulka milmay ee carrageenan waxayna soo saaraan jel xoog hoose, ama waxay gacan ka geystaan joojinta jel (lambda carrageenan).
Noocyo badan oo algae cas ah ayaa soo saara noocyo kala duwan oo carrageenans ah inta lagu jiro taariikhda korriinka. Tusaale ahaan, genus Gigartina waxay soo saartaa inta badan kappa carrageenans inta lagu jiro marxaladda gametophytic, iyo lambda carrageenans inta lagu jiro marxaladda sporophytic. Eeg Beddelka Jiilasha.
Dhammaantood waxay ku milmeen biyo kulul, laakiin, biyaha qabow, kaliya qaabka lambda (iyo cusbada sodium ee labada kale) waa milma.
Marka loo isticmaalo alaabta cuntada, carrageenan waxa uu leeyahay E-number E407 ama E407a wax lagu daro ee EU marka loo eego "seweed eucheuma la farsameeyey", waxaana caadi ahaan loo isticmaalaa emulsifier ahaan.
Qaybo ka mid ah Scotland (halkaas oo loo yaqaan (An) Cairgean ee Scottish Gaelic) iyo Ireland (nooc la isticmaalo waa Chondrus Crispus oo loo yaqaan Irish Gaelic si kala duwan sida carraigín [dhagaxa yar], fiadháin [walxaha duurjoogta], clúimhín cait [cat's puff] , mathair an duilisg [hooyada badda badda], ceann donn [madaxa cas]), waxaa loo yaqaanaa Carrageen Moss waxaa lagu kariyaa caano oo la miiro, ka hor inta aan lagu darin sonkorta iyo dhadhanka kale sida vaniljka, qorfe, brandy, ama whiskey. Badeecada dhamaadka waa nooc jelly ah oo la mid ah pannacotta, tapioca, ama blancmange.
Marka iota carrageenan lagu daro sodium stearoyl lactylate (SSL), saameyn isku-dhafan ayaa la abuuray, taas oo u oggolaanaysa xasilinta iyo emulsifying aan la helin nooc kale oo carrageenan ah (kappa / lambda) ama emulsifiers kale (mono iyo diglycerides, iwm.). SSL oo lagu daray iota carrageenan, waxay awood u leedahay inay soo saarto emulsions iyada oo la adeegsanayo xaaladaha kulul iyo qabow labadaba iyada oo la adeegsanayo khudradda ama dufanka xayawaanka.
Dalka Maraykanka, carrageenan waa maaddooyin ku jira caanaha soy-ga oo lagu iibiyo astaanta Cuntooyinka Dhan.
