Carrageenan - chii? Zvakaipei anoita stabilizer carrageenan

Food yokuvirisa (stabilizers) zvikuru kushandiswa dheri, confectionery, nyama, bhekari indasitiri. Pamusana kushandisa kwavo zvigadzirwa panguva zvandinenge chimiro, magadzirirwo uye kusachinja-chinja. Munguva ichangopfuura, mu nevakawanda senzira stabilizer carrageenan. Chii? Munyaya ino tichashandisa kukurira nyaya iyi.

Carrageenan inotengwa somugumisiro kubudiswa zvomumvura dzvuku algae Rhodophyceae mhuri. algae aya dzabudapo zvinenge zvose mumvura paNyika. Red algae - rudo kupisa-miti, saka, sezvo mutemo, vanogona kuonekwa pamahombekombe Indonesia, France, Chile, USA uye Canada.

Stabilizer carrageenan - wechisikigo gelling mumiriri, thickener. Izvi chinamatidzwa muviri iri zvinowanzoshandiswa anogadzira zvinhu nomukaka zvigadzirwa, confectionery, soseji uye zvinogadzirwa hove. Pasina carrageenan zvakakwana uye kugadzirwa aizikirimu, nokuti achionga yaro creamy kusachinja-chinja kunokwanisika nokushandisa rokupedzisira chigadzirwa.

Carrageenan: Overview

Carrageenan yakavhurwa mukupera kwezana remakore rechi19, asi kusvikira zvino fuma iri sezvo ongororo uye inoshanda kufarira kune masayendisiti akawanda munyika. The emakambani rokutanga maindasitiri kubudiswa carrageenan akazviratidza muUnited States vari pakati 30-ies pamusoro XX remakore. Parizvino, kune vanopfuura zviuru 3 mhando carrageenan, uye ichi hachisi yokupedzisira nhamba. Gore negore, vaongorori kuwana mhando itsva carrageenan. Kubva ikozvino, munoziva, kana yakavhurwa carrageenan, chii, uye mune zvipi rinoshandiswa.

Nepo nekunhonga zvoutachiona kukura danho, uyewo ukuru uye locus dzvuku algae sei physico-zvemakemikari ehupfumi kuti carrageenan. Nokuda kwezvinhu kubudiswa algae inotengwa carrageenans dzinoverengeka zvikamu zviduku, izvo zvakasiyana makemikari anoumba, uyewo humwe unhu zviratidzo. Panguva ino, pane vatatu makirasi carrageenan, dzakasiyana mune mwero sulphation: kappa, vara duku uye lambda carrageenans.

Kappa-carrageenan, Chinyiko ichi?

Kirasi uyu carrageenans iri nyore soluble mumvura inopisa. Mushure nemukuparadzwa kwaizotevera kutonhora, zvinoumba gel dzakakwirira simba mondo. Gels kappa kirasi wakanaka zvakanaka sei mukaka mapurotini. Panguva zvaAtemisi nyama zvigadzirwa sezvokudya chirungiso inoshandiswa kappa-carrageenan. Pokushandisa fuma nokuda kukwanisa kuwedzera kune viscosity pamusoro mvura uye chiito somunhu thickener, kwete chete, asi wavawo emulsifier.

mhando carrageenan

By ukuru wokunatswa carrageenans zvinogona semhosva Semi-ndarama uye akanatswa. Mugumisiro wokutanga inotengwa achibika matope iri alkaline mhinduro. Zvadaro, crystals vari yakasvinwa carrageenans, pfungwa uye vakabviswa mumushonga. Nzira iyi ndiyo nani nguva unoparadza uye zvinodhura. Most inowanzoshandiswa indasitiri Semi-vakanatswa carrageenan. Izvi rworudzi algae inotengwa nevanhu kubika mhinduro kuti potassium hydroxide. Potassium kunodzivisa hydrolysis kuti carrageenan iri mhinduro, asi anobvumira kuiparadza makabhohaidhiretsi uye mapurotini algae. Mushure date kuchinja ari matope mhinduro yabviswa, kushambidzwa uye akaomeswa.

Vara, uye lambda-carrageenan, Chinyiko ichi?

Vara duku-carrageenan anoumba munhu gel simba zvichienzaniswa kappa-gel. Zvinokosha kucherechedza kuti gels vakadaro zvakawanda kwakavharwa nenyama, vanokwanisa kudzorera nechivako yaro yepakutanga kunyange pashure zvokuimba zvazvinoita. Panyaya iyi, vara duku-carrageenan unowanzoshandiswa senzira stabilizer pamusoro suspensions. Kunze pamusoro akapa jellies zvakakwana kugadzikana panguva anotevedzana Zvinonzi nechando / thawing.

Lambda-carrageenan hakuiti kuumba gels nokuti unosanganisira zhinji sulfo-mapoka, asi izvozvo mhinduro vane mukuru viscosity. Saka, chikamu chiduku ichi ndiyo yakanaka paumbwe emulsions, furo uye suspensions.

Kushandisa zvokudya chirungiso carrageenan

Pane ruzivo kuti zvokudya stabilizer carrageenan yakachengeteka utano hwedu, mukuwedzera, ine nhamba nemamwe anobatsira zvivako. Nyanzvi dzakawanda vari pfungwa kuti chikuru kubatsira kushandisa fuma iyi - pakuchenesa muviri kubva chepfu uye nemakemikari netsvina biosoedineny, kusanganisira inorema simbi. Uyezve, zvinonzi vakaratidza kuti carrageenans havasi allergens kuratidza antiviral, anticoagulant, Anti-kwemabhakitiriya uye Anti-muchetura mugumisiro.

Carrageenan: kukuvadza

Masayendisiti US vakaratidza kuti inonyadzisa carrageenan kungamutsawo kukura zvirwere nemudumbu, uyewo kenza. Chii carrageenan ngozi? Kunokanganisa kuti chirungiso anogona chokuita chokwadi kuti pakugadzira kushingaira fuma kutsamwisa kukura anogumbura siyana pamuviri. Carrageenan panguva hydrolysis mudumbu anosunungura zvine chepfu, inova hwaro kwezvirwere anopfuura zana. Pakati pavo, gastritis, enteritis, colitis, arthritis, atherosclerosis, uye zvichingodaro. D. inonyadzisa carrageenan zvinokuvadza utano hwedu, saka kakawanda zvisiri zvokudya.

Munguva ichangopfuura, vamiririri WHO anokurudzira zvakasimba kushandiswa yokuvirisa vari zvigadzirwa, ayo aida kuti muviri vana navakadzi pamuviri. Recent zvidzidzo zvokuongorora masayendisiti American inoitwa dziri mumarabhoritari mhuka zvakaratidza kuti poliginan (chikamu carrageenan mamorekuru) anogona kukonzera maronda uye zvomudumbu kenza turakiti. akati zvokudya stabilizer pahwaro ari kugamuchira mashoko haasi yakawira muchikwata che wairambidza Mishonga zvokuwedzera, asi mhaka pathologies zhinji unogona vachiri kushumira, saka kudya zvokudya zvine carrageenan (zvokudya chirungiso E-407 uye E-407a) vanofanira kuva nokungwarira. Pasinei nekusimba toxicity, stabilizer E-407 anobvumirwa kushandisa nenyika vakawanda rinoti, kusanganisira Russian Federation. Zvisinei, sarudzo ndeyako, shamwari dzangu.
