Cov khoom lag luam
Carrageenan yog Semi Refaced Khoom Noj Qib Kappa Karrageenan (E407A) muab rho tawm los ntawm Eucheuma Rwb Rwbweeds. Nws ua cov thermoreversible gels ntawm kev pom zoo thiab muaj kev nkag siab txog cov poov tshuaj ion uas ua tau zoo tshaj nws cov khoom siv. Carrageenan yog ruaj khov nyob rau hauv alkali nruab nrab. Carrageenan yog ib qho ib txwm - tshwm sim ntawm carbohydrates tau muab rho tawm los ntawm cov dej hiav txwv liab los yog cov kev mob alkaline ntawm qhov kub thiab txias. Refined Carrageenan feem ntau yog zoo tu los ntawm kev daws los ntawm dej nag los yog dej nag lossis cov poov tshuaj gelation.
Semi - Ua kom zoo li Carrageenan tau ntxuav thiab Alkali kho seaweed seaweed. Tus cab kuj tsis raug rho tawm ntawm seaweed tab sis tseem muaj nyob hauv cov xovtooj ntawm tes matrix. Kev ua lag luam Carrageenan cov khoom lag luam muaj feem ntau cov qauv rau tau txais kev ua kom zoo tshaj plaws thiab thickening cov khoom. Los ntawm kev siv cov khoom lag luam uas tsim nyog transrage Ntxiv rau kev muab hom qauv, ua haujlwm ua haujlwm nrog nrog cov neeg siv khoom tsim cov khoom lag luam tshiab thiab cov qauv rau cov ntaub ntawv tshwj xeeb tshiab.
Carrageenans muaj cov lwg loj heev, hloov kho uas tau tsim txoj kev sib hlub cov qauv helical. Qhov no muab rau lawv muaj peev xwm los ua ntau yam ntawm cov gels ntawm chav tsev kub. Lawv tau dav siv hauv cov zaub mov thiab lwm yam kev lag luam li thickening thiab stabilizing cov neeg sawv cev. Ib qho txiaj ntsig tshwj xeeb yog tias lawv muaj pseudoplastic-lawv nyias nyob rau hauv shear kev nyuaj siab thiab rov qab zoo li lawv viscosity ib zaug qhov kev ntxhov siab raug tshem tawm. Qhov no txhais tau tias lawv yooj yim tso kua mis, tab sis stiffen dua tom qab.
Txhua tus neeg nqa zaub mov muaj siab - molecular - hnyav polysaccharides ua los ntawm kev rov ua dua cov chav ua haujlwm galactose (3,6 - ag), ob qho tib si sulfated thiab nonsulfated thiab nonsulfated thiab no Cov koog tau koom nrog los ntawm kev sib hloov Alpha 1-3 thiab beta 1-4 glycosidic sib txuas.
Muaj peb chav ua lag luam tseem ceeb ntawm Carrageenan:
Kappa foos muaj zog, cov kua nplaum txhav hauv lub xub ntiag ntawm potassium ions; Nws reacts nrog mis nyuj protein. Nws yog sourced tsuas yog los ntawm Kappaiphycus alvarezii [3] cov ntawv muag muag muag nyob rau hauv muaj cov calcium calcium. Nws yog tsim tawm los ntawm Eucheuma Denticulatum.lambda tsis gel, thiab yog siv los tuab tuab cov khoom lag luam. Cov peev txheej tshaj plaws yog gigartina los ntawm South America .Thaum thawj cov khoom siv ntawm cov pab pawg thiab cov khoom ester sulfate ntawm cov chav nyob ua ke. Cov qib siab tshaj plaws ntawm Ester Sulfate qis dua cov solubility kub ntawm cov cab kuj thiab ua rau cov kua txiv ntoo qis dua, lossis ua rau gel inhibition (Lambda Carrageenan).
Ntau hom liab liab cog qoob loo ntau yam ntawm cov neeg nqa khoom hauv cov neeg nqa khoom thaum lawv muaj keeb kwm kev loj hlob. Piv txwv li cov genus gigartina ua tau yooj yim kappa carrageenans thaum lub sij hawm gametophyticic, thiab Lambda Carrageenans thaum lub sijhawm tsheb kauj vab. Saib kev hloov chaw ntawm ntau tiam neeg.
Txhua yam yog soluble hauv dej kub, tab sis, hauv dej txias, tsuas yog tus yaj yaj yaj (thiab cov ntsev ntsev ntawm lwm ob) yog soluble.
Thaum siv nyob rau hauv cov khoom noj khoom haus, Carrageenan muaj EU Additive E - Tus lej E407 lossis e407 lossis eUcheuma seaweed ", thiab yog siv ua ib qho emulsifier.
Hauv qhov chaw ntawm Scotland (qhov uas nws tau hu ua (A) Cairsan nyob rau hauv Irish Gualus), Fiadhic Crispus), FiadhiG), Curúomhin (Mirlhand Nws yog lub npe hu ua Carrageen Moss nws yog boiled nyob rau hauv cov mis nyuj thiab lim, ua ntej qab zib thiab lwm yam tsw xws li vanilla, cinnamon, whiskey ntxiv. Qhov kawg - cov khoom yog ib hom jelly zoo ib yam li pannacotta, tapioca, lossis blancmange.
Thaum iota Carrageenan ua ke nrog sodium stearoyl lactylize (SSL SSL ua ke nrog iota carrageenan, muaj peev xwm ua tau emulsions nyob rau hauv ob qho chaw kub thiab txias siv cov zaub lossis tsiaj rog.
Hauv Tebchaws Meskas, Carrageenan yog ib qho khoom xyaw hauv cov mis nyuj muag hauv qab cov khoom noj tag nrho.
