Products Description
Carrageenan ihafu yakanatswa chikafu giredhi Kappa Karrageenan (E407a) yakatorwa kubva muEucheuma cottonii sora regungwa.Iyo inoumba thermoreversible gels panguva yakakwana yekuisa uye inonzwa zvakanyanya kune potassium ion iyo inowedzera zvikuru gelling yayo.Carrageenan yakagadzikana mune alkali medium.Carrageenan imhuri inongoitika yega yemacarbohydrates akatorwa kubva mugungwa dzvuku.Yakanatswa carrageenan inonyanya kudzoserwa kubva mumhinduro nekunaya kwedoro kana potassium gelation.
Semi-yakanatswa carrageenan inogezwa uye alkali inorapwa sowe remugungwa.Iyo carrageenan haina kubviswa kubva mugungwa asi ichiri musero madziro matrix.Commercial carrageenan zvigadzirwa zvinowanzogadziriswa kuti uwane yakakwana gelling uye thickening zvivakwa.Nekushandisa iyo yakakodzera carrageenan chigadzirwa, mugadziri anogona kugadzira mavara kubva kune yakasununguka-inoyerera zvinwiwa kusvika kune yakasimba gels.Pamusoro pekupa marudzi akajairwa, COLORCOM inoshanda pamwe chete nevatengi kugadzira zvigadzirwa zvitsva uye magadzirirwo ezvakananga maapplication.
Carrageenans mahombe, anochinjika zvakanyanya mamorekuru anomonereka achigadzira helical zvimiro.Izvi zvinovapa kukwanisa kuumba zvakasiyana-siyana zvakasiyana-siyana gel pane tembiricha yekamuri.Iwo anoshandiswa zvakanyanya mukudya uye mamwe maindasitiri sekukora uye kudzikamisa vamiririri.Chimwe chakanakira ndechekuti ivo vari pseudoplastic-vanoonda pasi pekunetseka kwekugera uye vanodzoreredza viscosity yavo kana kushushikana kwabviswa.Izvi zvinoreva kuti zviri nyore kupomba, asi kuomesa zvakare mushure.
Yese ma carrageenans ane high-molecular-weight polysaccharides akaumbwa nekudzokorora zvikamu zvegalactose uye 3,6 anhydrogalactose (3,6-AG), zvose zvakasvibiswa uye zvisina kushandiswa.Iwo mayunitsi anobatanidzwa nekuchinjanisa alpha 1–3 uye beta 1–4 glycosidic linkages.
Kune matatu makirasi makuru ekutengesa e carrageenan:
Kappa inoumba gels yakasimba, yakaoma muhupo hwe potassium ions;inopindirana nemaProteins emukaka.Inotorwa zvakanyanya kubva kuKappaphycus alvarezii[3] .Iota inoumba gel dzakapfava muhupo hwe calcium ions.Iyo inogadzirwa zvakanyanya kubva kuEucheuma denticulatum.Lambda haina gel, uye inoshandiswa kukora zvigadzirwa zvemukaka.Kunyanya kunowanikwa iGigartina kubva kuSouth America.Misiyano yepakutanga inobata maitiro e kappa, iota, uye lambda carrageenan nhamba uye nzvimbo yemapoka ester sulfate pazvikamu zvegalactose zvinodzokorora.Mazinga epamusoro eester sulfate anodzikisa kupisa kwekunyungudika kwecarrageenan uye kuburitsa gels simba rakaderera, kana kubatsira kukudzivirira kwegel (lambda carrageenan).
Mhando dzakawanda dzealgal dzvuku dzinobudisa marudzi akasiyana e carrageenans panguva yekukura kwavo nhoroondo.Semuyenzaniso, iyo genus Gigartina inoburitsa kunyanya kappa carrageenans panguva yayo gametophytic nhanho, uye lambda carrageenans panguva yayo sporophytic nhanho.Ona Kuchinjana kwezvizvarwa.
Zvese zvinonyungudika mumvura inopisa, asi mumvura inotonhora, fomu re lambda chete (uye sodium munyu yemamwe maviri) inonyungudika.
Kana ichishandiswa muzvigadzirwa zvekudya, carrageenan ine EU additive E-number E407 kana E407a kana iripo se "processed eucheuma seaweed", uye inowanzoshandiswa semulsifier.
Munzvimbo dzeScotland (kwainozivikanwa se (An) Cairgean muScottish Gaelic) neIreland (yakasiyana inoshandiswa ndiChondrus Crispus inozivikanwa muIrish Gaelic zvakasiyana se carraigín [dombo diki], fiadháin [zvinhu zvemusango], clúimhín cait [katsi puff] , mathair an duilisg [mother of seaweeds], ceann donn [red head]), inozivikanwa seCarrageen Moss inobikwa nemukaka nekusefa, isati yaiswa shuga nezvimwe zvinonhuwirira zvakaita sevanilla, sinamoni, brandy, kana whisky.Iyo yekupedzisira-chigadzirwa imhando yejelly yakafanana nepannacotta, tapioca, kana blancmange.
Kana iota carrageenan yasanganiswa ne sodium stearoyl lactylate (SSL), synergistic effect inogadzirwa, inobvumira kudzikamisa uye emulsifying isingawanikwe neimwe mhando ye carrageenan (kappa/lambda) kana nemamwe emulsifiers (mono uye diglycerides, nezvimwewo).SSL yakasanganiswa neota carrageenan, inokwanisa kugadzira emulsion pasi pemamiriro ese ekupisa nekutonhora vachishandisa mafuta emuriwo kana emhuka.
MuUnited States, carrageenan inhengo mumukaka wesoya unotengeswa pasi pemhando yeWhole Foods.
