Carrageenan ni igice cyibiryo bitunganijwe neza Kappa Karrageenan (E407a) yakuwe muri Eucheuma cottonii ibyatsi byo mu nyanja. Ikora geles yumuriro mwinshi cyane kandi yunvikana cyane kuri potasiyumu ion yongerera cyane imiterere yayo. Carrageenan ihagaze neza muri alkali. Carrageenan ni umuryango usanzwe uboneka wa karubone ya hydrata ikurwa mu byatsi bitukura byo mu nyanja .. Carrageenan ikuramo amazi mu bihe bitagira aho bibogamiye cyangwa alkaline ku bushyuhe bwo hejuru. Carrageenan itunganijwe neza igarurwa mubisubizo byimvura igwa cyangwa potasiyumu.

Semage itunganijwe neza karrageenan irakaraba kandi alkali ivura ibyatsi byo mu nyanja. Carrageenan ntabwo ikurwa mubyatsi byo mu nyanja ariko iracyari muri matrise ya selile. Ibicuruzwa bya karrageenan yubucuruzi bikunze kugereranywa kugirango ubone ibyiza bya gelling no kubyimba. Ukoresheje ibicuruzwa bya karrageenan bikwiye, uwabishizeho arashobora gukora imiterere kuva kumazi atemba yubusa kugeza kuri gele ikomeye. Usibye gutanga ubwoko busanzwe, COLORCOM ikora ifatanije nabakiriya kugirango batezimbere ibicuruzwa bishya nibisobanuro byihariye.

Carrageenans nini, yoroheje cyane ya molekile ihindagurika ikora ibintu byubaka. Ibi bibaha ubushobozi bwo gukora geles zitandukanye mubushyuhe bwicyumba. Zikoreshwa cyane mu biribwa no mu zindi nganda nko kubyimba no guhagarika ibintu. Akarusho kihariye ni uko ari pseudoplastique - inanutse kubera guhangayika kandi igarura ubwiza bwayo iyo imihangayiko imaze kuvaho. Ibi bivuze ko byoroshye kuvoma, ariko byongeye gukomera nyuma.

Carrageenans yose ni polisikaride ifite uburemere buke bugizwe no gusubiramo ibice bya galaktose hamwe na 3,6 anhydrogalactose (3,6-AG), byombi bya sulfate kandi bidafite isukari. Ibice byahujwe no guhinduranya alfa 1–3 na beta 1-4 glycosidic ihuza.

Hariho ibyiciro bitatu byingenzi byubucuruzi bya karrageenan:

Kappa ikora geles ikomeye, ikomeye imbere ya ion ya potasiyumu; ikora hamwe na poroteyine y’amata. Bikomoka cyane cyane kuri Kappaphycus alvarezii [3] .Iota ikora geles yoroshye imbere ya calcium ion. Ihingurwa cyane cyane muri Eucheuma denticulatum.Lambda ntabwo ije, kandi ikoreshwa mubyimbye byamata. Inkomoko ikunze kugaragara cyane ni Gigartina ukomoka muri Amerika yepfo. Itandukaniro ryibanze rigira ingaruka kumiterere ya kappa, iota, na lambda carrageenan numubare numwanya wamatsinda ya ester sulfate kubice bisubiramo galaktose. Urwego rwo hejuru rwa ester sulfate rugabanya ubushyuhe bwo gukonjesha bwa karrageenan kandi bikabyara geles nkeya, cyangwa bigira uruhare mukubuza gel (lambda carrageenan).

Ubwoko bwinshi butukura bwa algal butanga ubwoko butandukanye bwa karrageenans mugihe cyamateka yiterambere. Kurugero, ubwoko bwa Gigartina butanga cyane cyane kappa karrageenans mugihe cyayo ya gametophytike, na lambda karrageenans mugihe cyayo cya sporofitike. Reba Ibisekuruza.

Byose birashobora gushonga mumazi ashyushye, ariko, mumazi akonje, gusa form ya lambda (numunyu wa sodiumi yandi abiri) irashonga.

Iyo ikoreshejwe mubicuruzwa byibiribwa, karrageenan ifite EU yongeyeho E-nimero E407 cyangwa E407a mugihe ihari nka "eucheuma yo mu nyanja yatunganijwe", kandi ikoreshwa nka emulisiferi.

Mu bice bya Scotland (aho bizwi nka (An) Cairgean muri Scottish Gaelic) na Irilande (ubwoko bukoreshwa ni Chondrus Crispus uzwi muri Gaelic yo muri Irlande bitandukanye nka carraigín [urutare ruto], fiadháin [ibintu byo mu gasozi], clúimhín cait [puff's puff] . Ibicuruzwa byanyuma ni ubwoko bwa jelly busa na pannacotta, tapioca, cyangwa blancmange.

Iyo iota carrageenan ihujwe na sodium stearoyl lactylate (SSL), hashyirwaho ingaruka zo guhuza imbaraga, bigatuma habaho gutuza no kwigana kutabonetse hamwe nubundi bwoko bwa karrageenan (kappa / lambda) cyangwa nubundi buryo bwa emulisiferi (mono na diglyceride, nibindi). SSL ifatanije na iota carrageenan, irashobora gukora emulisiyo mubihe bishyushye nubukonje ukoresheje amavuta yimboga cyangwa inyamaswa.

Muri Amerika, karrageenan ni kimwe mu bigize amata ya soya agurishwa munsi yikirango cyuzuye.
