Carrageenan ndi kalasi yazakudya zoyengedwa bwino kwambiri za Kappa Karrageenan (E407a) zotengedwa ku udzu wa m'nyanja wa Eucheuma cottonii. Amapanga ma gels otenthetsera pamlingo wokwanira ndipo amakhudzidwa kwambiri ndi ayoni a potaziyamu omwe amawonjezera kwambiri ma gelling. Carrageenan ndi wokhazikika mu alkali medium. Carrageenan ndi banja lomwe limapezeka mwachilengedwe lazakudya zomwe zimachotsedwa mumadzi ofiira a m'nyanja. Carrageenan yoyengedwa imapezeka makamaka kuchokera ku njira yothetsera mowa ndi mvula kapena potaziyamu.

Semi-woyengedwa carrageenan amatsukidwa ndi madzi amchere amchere. Carrageenan samachotsedwa m'madzi am'nyanja koma akadali mu cell wall matrix. Zamalonda zamalonda za carrageenan nthawi zambiri zimakhala zokhazikika kuti zipeze ma gelling abwino komanso makulidwe. Pogwiritsa ntchito mankhwala oyenerera a carrageenan, wopanga akhoza kupanga zojambula kuchokera ku zakumwa zopanda madzi kupita ku ma gels olimba. Kuphatikiza pa kupereka mitundu yokhazikika, COLORCOM imagwira ntchito limodzi ndi makasitomala kuti apange zinthu zatsopano ndi mapangidwe azinthu zina.

Ma Carrageenans ndi mamolekyu akulu, osinthika kwambiri omwe amapindika ndikupanga ma helical. Izi zimawapatsa mwayi wopanga ma gels osiyanasiyana osiyanasiyana kutentha kutentha. Amagwiritsidwa ntchito kwambiri muzakudya ndi m'mafakitale ena monga thickening ndi stabilizing agents. Ubwino wina ndi wakuti iwo ndi pseudoplastic - amawonda pansi pa kumeta ubweya wa ubweya ndikubwezeretsa kukhuthala kwawo pamene kupsinjika kumachotsedwa. Izi zikutanthauza kuti ndizosavuta kupopa, koma zimaumanso pambuyo pake.

Ma carrageenans onse ndi ma polysaccharides olemera kwambiri a molekyulu opangidwa ndi mayunitsi a galactose obwerezabwereza ndi 3,6 anhydrogalactose (3,6-AG), onse omwe ali ndi sulfated komanso osasunthika. Mayunitsiwa amalumikizidwa ndi kusinthana kwa alpha 1-3 ndi beta 1-4 glycosidic maulalo.

Pali magulu atatu akuluakulu azamalonda a carrageenan:

Kappa amapanga ma gels amphamvu, olimba pamaso pa ayoni a potaziyamu; imakhudzidwa ndi Mapuloteni a mkaka. Amachokera makamaka ku Kappaphycus alvarezii[3] .Iota imapanga ma gel ofewa pamaso pa ayoni a calcium. Amapangidwa makamaka kuchokera ku Eucheuma denticulatum.Lambda sakhala ndi gel, ndipo amagwiritsidwa ntchito kulimbitsa mkaka. Gwero lodziwika kwambiri ndi Gigartina wochokera ku South America.Kusiyana kwakukulu komwe kumakhudza katundu wa kappa, iota, ndi lambda carrageenan ndi chiwerengero ndi malo a magulu a ester sulfate pamagulu obwerezabwereza a galactose. Miyezo yapamwamba ya ester sulfate imachepetsa kutentha kwa carrageenan ndikupanga ma gel otsika kwambiri, kapena imathandizira kuletsa kwa gel (lambda carrageenan).

Mitundu yambiri ya algal yofiira imatulutsa mitundu yosiyanasiyana ya carrageenans panthawi ya chitukuko chawo. Mwachitsanzo, mtundu wa Gigartina umatulutsa makamaka kappa carrageenans panthawi yake ya gametophytic, ndi lambda carrageenans panthawi yake ya sporophytic. Onani Kusinthana kwa mibadwo.

Zonse zimasungunuka m'madzi otentha, koma, m'madzi ozizira, mawonekedwe a lambda okha (ndi mchere wa sodium wa ena awiriwo) amasungunuka.

Ikagwiritsidwa ntchito muzakudya, carrageenan imakhala ndi chowonjezera cha EU E-nambala E407 kapena E407a ikakhalapo ngati "m'nyanja yamchere ya eucheuma", ndipo imagwiritsidwa ntchito ngati emulsifier.

M'madera ena a Scotland (komwe amadziwika kuti (An) Cairgean mu Scottish Gaelic) ndi Ireland (zosiyanasiyana zomwe zimagwiritsidwa ntchito ndi Chondrus Crispus yemwe amadziwika mu Irish Gaelic mosiyanasiyana monga carraigín [thanthwe], fiadháin [zinthu zakutchire], clúimhín cait [mpukutu wa mphaka] , mathair an duilisg [mother of seaweeds], ceann donn [red head]), amadziwika kuti Carrageen Moss amawiritsidwa mumkaka ndikusefa, asanawonjezere shuga ndi zokometsera zina monga vanila, sinamoni, brandy, kapena whiskey. Mapeto ake ndi mtundu wa jelly wofanana ndi pannacotta, tapioca, kapena blancmange.

Iota carrageenan ikaphatikizidwa ndi sodium stearoyl lactylate (SSL), mphamvu ya synergistic imapangidwa, kulola kukhazikika ndi emulsifying osapezeka ndi mtundu wina uliwonse wa carrageenan (kappa/lambda) kapena ndi emulsifiers ena (mono ndi diglycerides, etc.). SSL yophatikizidwa ndi iota carrageenan, imatha kupanga emulsion pansi pa kutentha ndi kuzizira pogwiritsa ntchito masamba kapena mafuta anyama.

Ku United States, carrageenan ndi chophatikizira mu mkaka wa soya wogulitsidwa pansi pa mtundu wa Whole Foods.
