Carrageenan - yog dab tsi? Kev phem dab tsi tsis stabilizer carrageenan

Khoom noj khoom haus additives (stabilizers) lug siv nyob rau hauv lub mis nyuj, confectionery, nqaij, bakery kev lag luam. Tsaug rau lawv siv ntawm cov khoom nyob rau ntawm lub lub Desired zoo, kev ntxhib los mos thiab taub hau. Tsis ntev los no, nyob rau hauv dav siv raws li ib tug stabilizer carrageenan. Yuav ua li cas yog nws? Nyob rau hauv no tsab xov xwm peb yuav nrog qhov teeb meem no.

Carrageenan yog tau raws li ib tug tshwm sim ntawm kev ntawm marine liab algae Rhodophyceae tsev neeg. Cov algae yog zus nyob rau hauv yuav luag tag nrho cov ntiaj teb tus dej. Liab algae - Thaum tshav kub kub-hlub nroj tsuag, li ntawd, raws li ib tug txoj cai, lawv yuav pom nyob rau hauv lub ntug dej hiav txwv ntawm Indonesia, Fabkis, Chile, Teb chaws USA thiab Canada.

Stabilizer carrageenan - ib tug natural gelling neeg sawv cev, thickener. Qhov no noj haus ntxiv yog dav siv nyob rau hauv qhov siv thiab ua khoom noj siv mis, confectionery, hnyuv ntxwm thiab ntses khoom. Tsis muaj carrageenan tiav thiab zus tau tej cov mis nyuj khov, vim hais tias nws yog ua tsaug rau nws cov creamy taub hau yog tiav los ntawm kev siv ntawm cov khoom muag kawg.

Carrageenan: Txheej txheem cej luam

Carrageenan twb qhib nyob rau hauv lub lig puv 19 xyoo pua, tab sis, thaum tam sim no no substance yog raws li ib tug kev tshawb fawb thiab cov tswv yim txaus siab rau ntau zaum nyob rau hauv lub ntiaj teb no. Tus thawj qhauj nyob rau hauv lub muaj ua ntawm carrageenan nyob rau hauv lub tebchaws United States nyob rau hauv nruab nrab 30-ies ntawm XX caug xyoo. Tam sim no, muaj ntau tshaj 3 txhiab hom carrageenan, thiab qhov no yog tsis yog qhov kawg daim duab. Txhua txhua xyoo, soj ntsuam nrhiav tus tshiab hom carrageenan. Txij no mus, koj paub, thaum nws qhib carrageenan, nws yog dab tsi, thiab nyob rau hauv dab tsi thaj chaw nws yog siv.

Thaum sau lom theem kev loj hlob, raws li zoo raws li lub qhov tob thiab lub locus ntawm liab algae cuam tshuam rau physico-tshuaj thaj chaw ntawm carrageenan. Vim hais tias ntawm cov kev siv technology tshiab ua ntawm algae yog tau carrageenans ob peb fractions, uas txawv nyob rau hauv lawv cov tshuaj nyob tus yeees, raws li zoo li lwm yam kev ntsuas kev. Thaum lub sij hawm no, muaj peb cov chav kawm ntawv carrageenan, differing nyob rau hauv degree ntawm sulphation: kappa, iota thiab lambda carrageenans.

Kappa-carrageenan, yog dab tsi no?

Qhov no hauv chav kawm ntawv ntawm carrageenans yog nkag soluble nyob rau hauv dej kub. Tom qab nyias mus nyias thiab tom ntej cua txias, lawv tsim ib tug gel uas muaj zog jelly. Gels kappa chav kawm ntawv zoo zoo nkauj hnov mob nrog mis nyuj proteins. Thaum lub sij hawm siv thiab ua cov nqaij cov khoom raws li ib tug khoom noj khoom haus additive siv yog kappa-carrageenan. Daim ntawv thov ntawm cov tshuaj yeeb dej caw vim cov muaj peev xwm yuav ua tau kom lub viscosity kua thiab ua raws li ib tug thickener, tsis zoo xwb, tab sis kuj yog ib tug emulsifier.

hom carrageenan

Los ntawm cov neeg kawm ntawv ntawm purification ntawm carrageenans yuav dej num raws li semi-refined thiab refined. Tus thawj tshwm sim yog tau boiling seaweed nyob rau hauv ib tug alkaline tov. Tom qab ntawd, cov muaju yog lim carrageenans, feeb meej thiab muab tshem tawm los ntawm cov tshuaj. Qhov no txoj kev yog es lub sij hawm siv thiab kim heev. Feem ntau cov feem ntau siv nyob rau hauv qhov kev lag luam semi-refined carrageenan. Qhov no hom ntawm algae yog tau los ntawm boiling ib tug tov ntawm poov tshuaj hydroxide. Poov tshuaj tiv thaiv hydrolysis ntawm carrageenan nyob rau hauv cov tshuaj, tab sis tso cai yaj carbohydrates thiab proteins algae. Tom qab cov ntaub ntawv manipulation ntawm cov seaweed tov yog muab tshem tawm, ntxuav thiab qhuav.

Iota, thiab lambda-carrageenan, yog dab tsi no?

Iota-carrageenan ntaub ntawv ib tug weaker gel piv rau kappa-gel. Nws yog ib nqi sau cia hais tias xws li tshuaj kua yog ntau dua ywj, lawv yuav tau los nws cov thawj cov qauv txawm tias tom qab ib tug txhua yam kev cuam tshuam. Nyob rau hauv no hais txog, iota-carrageenan yog feem ntau yog siv raws li ib tug stabilizer ntawm ncua. Dhau li ntawm tus saum toj no hais jellies sufficiently ruaj khov ntawm successive mus ntawm khov / yaj.

Lambda-carrageenan tsis tsim tshuaj kua vim hais tias nws muaj xws li ib tug zoo kawg tooj ntawm sulfo-pawg, tab sis xws dlaws muaj lub siab viscosity. Yog li ntawd, qhov no feem yog zoo tagnrho rau cov tsim ntawm emulsions, foams thiab ncua.

Siv ib cov zaub mov additive carrageenan

Muaj cov ntaub ntawv uas ib tug khoom noj khoom haus stabilizer carrageenan muaj kev ruaj ntseg rau peb kev, nyob rau hauv tas li ntawd, nws muaj ib tug xov tooj ntawm txawv pab zog. Muaj ntau cov kws txawj yog ntawm lub tswv yim hais tias lub ntsiab kev pab ntawm kev siv no substance - ntxuav tib neeg lub cev los ntawm tshuaj lom thiab tshuaj impurities biosoedineny, xws li hnyav hlau. Nyob rau hauv tas li ntawd, nws yog qhov tseeb hais tias carrageenans tsis allergens muaj antiviral, anticoagulant, anti-bacterial thiab anti-toxic nyhuv.

Carrageenan: raug mob

US zaum tau muaj pov thawj hais tias degraded carrageenan yuav ua rau txoj kev loj hlob ntawm cov kab mob ntawm tus mob huam, raws li zoo li mob cancer. Yuav ua li cas yog txaus ntshai carrageenan? Nws harms lub additive tej zaum yuav nrog nrog lub fact tias ib tug biologically active tshuaj ntxias txoj kev loj hlob ntawm inflammatory tshua nyob hauv lub cev. Carrageenan thaum lub sij hawm lub hydrolysis nyob rau hauv lub plab tawm tej yam tshuaj lom, uas yog lub hauv paus ntawm ntau tshaj ib puas yam kab mob. Ntawm lawv, gastritis, enteritis, mob plab, mob caj dab, atherosclerosis, thiab hais txog. D. degraded carrageenan yog teeb meem rau peb noj qab haus huv, li ntawd, nws yog feem ntau tsis muaj nyob rau hauv lub noj mov.

Tsis ntev los no, cov neeg sawv cev ntawm lub LEEJ TWG xav kom siv cov additives nyob rau hauv cov khoom, uas yog npaj rau cov kev noj haus ntawm cov me nyuam thiab poj niam xeeb tub. Tsis ntev los no sim kev tshawb fawb ntawm American zaum ua rau laboratory tsiaj tau qhia tias poliginan (ib feem carrageenan molecules) yuav ua rau ulcers thiab digestive ib ntsuj av tau cancer. hais tias cov zaub mov stabilizer rau lub hauv paus ntawm tus tau txais cov ntaub ntawv yog tsis poob rau hauv cov qeb ntawm txwv tsis pub noj tshuaj pab, tab sis qhov ua rau ntawm ntau pathologies nws yeej tseem ua hauj lwm, thiaj li noj cov khoom noj uas muaj carrageenan (khoom noj khoom haus additive E-407 thiab E-407a) yuav tsum ceev faj. Txawm tias cov pov thawj toxicity, stabilizer E-407 yog tso cai rau siv rau hauv ib ncig ntawm lub feem ntau ntawm lub xeev, nrog rau cov Lavxias teb sab Federation. Txawm li cas los, cov kev xaiv yog koj li, kuv cov phooj ywg.
