Carrageenan imagwiritsidwa ntchito, mwazinthu zina, pamakampani azakudya komanso opanga mankhwala. Ndi kuchotsedwa kwa ndere zofiira zomwe poyamba zimawoneka ngati zotetezeka.
koma imadzudzulidwa kwambiri chifukwa cha matenda omwe amabwera chifukwa chogwiritsa ntchito nthawi yayitali.
Dziwani m'nkhaniyi zonse zokhudzana ndi zakudya izi, zomwe mabungwe oyang'anira zakudya amaganiza, zinthu zomwe zilimo ndi zonse. kuopsa kwa carrageenan.
Kodi carrageenan ndi chiyani?
Carrageenan ndi chowonjezera chazakudya chomwe chimagwiritsidwa ntchito kukulitsa kuchuluka kwamafuta ochepa kapena zakudya zopatsa thanzi popanda kuwonjezera kuchuluka kwazakudya (1).
Chophatikizachi chimatha kukhala chojambulira, chokhazikika kapena chopangira emulsifier. Imagwira, makamaka, kukonza kapangidwe ka zakudya kuti zizikhala zofewa komanso zosasinthasintha.
Kukumbutsa, kuchuluka kwa kagwiritsidwe ntchito ka carrageenan kwawonjezeka kuchokera pa 5 mpaka 7% pachaka kuyambira 1973 chifukwa cha kuchuluka kwa anthu komanso kukula kwachuma.
Carrageenan amachokera ku algae wofiira wotchedwa "carrageenan". Algae awa amapezeka ku Brittany.
Kuphatikiza pa mbewu zomwe zikufunidwa kwambiri ndipo zikugwiritsidwa ntchito masiku ano zomwe zimachokera ku South America, dera la Brittany ndi lomwe limapanga ufa wambiri womwe umapezeka muzakudya zochepa zophikira ku France.
Chifukwa chiyani zimawerengedwa kuti ndizopangidwa zowona?
Ntchito za la carraghénane
Chomera cha m'madzi chakhala chikugwiritsidwa ntchito ngati chitetezo. Amagwiritsidwanso ntchito pochizira bronchitis, chifuwa chachikulu, chifuwa.
Anthu ena amagwiritsa ntchito carrageenan pochiza khungu kapena kumatako. Izi pogwiritsa ntchito kwanuko mozungulira anus kapena pakhungu lomwe lakhudzidwa.
Carrageenan amagwiritsidwanso ntchito mu mankhwala otsukira mano chakudya ndi mankhwala angapo. Amagwiritsidwanso ntchito mu mankhwala kuwonda.
Vuto limakhalapo pazakudya. Zowonadi, mankhwala otetezeka kwambiri amatha kukhala owopsa akagwiritsidwa ntchito mopitilira muyeso.
Zochita za carrageenan mthupi lanu
Carrageenan palokha imakhala ndi mankhwala omwe amakhudza kwambiri kutulutsa kwamatumbo (2).
Akatswiri a zamagetsi amakhulupirira kuti kumwa pang'ono kwa carrageenan sikukhudza m'mimba. Komabe, akamwedwa kwambiri komanso pafupipafupi, carrageenan imabweretsa madzi ochuluka m'matumbo, chifukwa chake amatulutsa mankhwala ofewetsa tuvi tolimba.
Popeza timadya carrageenan mopitirira muyeso, chifukwa imapezeka pafupifupi muzinthu zonse za ogula, ziwengo zina zimadza chifukwa.
Monga zamoyo zina zimazindikira kwambiri kuposa zina, zoyipa za carrageenan ndizambiri. Kukula kwawo kumasiyana mosiyana ndi munthu ndi munthu.
Anthu ena omwe amapondereza kumwa zakudya zachisanu ndi zina zotero; awona thanzi lawo likuyenda bwino kwambiri.
Carrageenan adanenedwa m'mitundu ingapo ya khansa ndi zovuta zingapo zam'mimba.
Mndandanda wosakwanira wazakudya zomwe zili ndi carrageenan
Zogulitsa Zakudya
Nawu mndandanda wazakudya zomwe zili ndi zowonjezera carrageenan:
- mkaka wa kokonati,
- Mkaka wa amondi,
- Ndine mkaka,
- Mpunga,
- Yogati,
- Tchizi,
- The ndiwo zochuluka mchere,
- Ayisi kirimu,
- Chokoleti cha mkaka,
- Zakudya zozizira monga pizza,
- Masoseji,
- Msuzi ndi msuzi,
- Mowa,
- msuzi,
- Timadziti ta zipatso.
- Zakudya za ziweto
Zogulitsa zomwe zili m'matumba sizingatchule za kuwonjezeredwa kwa carrageenan kapena opanga akhoza kuikapo chingamu cha dzombe pozindikira kuopsa kwa chowonjezera cha chakudya ichi.
Poterepa, yankho labwino kwambiri komanso lathanzi ndikudzigwiritsa ntchito popanga maphikidwe osavuta.
Muzamankhwala ndi zamankhwala
Carrageenan imagwiritsidwa ntchito mu:
- Zinthu zodzikongoletsera kuphatikiza ma shampoos ndi zowongolera, zonona, ma gels
- Opukuta nsapato
- Zozimitsa moto
- Kupanga pepala lokongoletsedwa
- umisiri
- Mankhwala.
Ku France carrageenan imagwiritsidwanso ntchito kuchiza zilonda zam'mimba
Zomwe mabungwe oyang'anira chakudya amaganiza
Mtsutso wokhudzana ndi zotsatira zoyipa za zowonjezera zowonjezera zakudya siwatsopano.
Titha kutchulapo, mwachitsanzo, za kagwiritsidwe ntchito ka zotsekemera zokometsera zotsekemera za sucralose paumoyo waumunthu, chinthu chomwe chingakhale chokhudzana ndi matenda a shuga kapena leukemia.
Ponena za vuto la carrageenan, zokambiranazi zidayamba zaka makumi asanu zapitazo.
Malingaliro a Joint FAO / WHO Expert Committee
M'malo mwake, ndikuwonjezera chakudya komwe kumagwira ntchito zingapo pazakudya zopangidwa, makamaka ngati zonenepa.
Zowonjezera carrageenan zili pandandanda "wodziwika kuti ndi wotetezeka" (3).
Komabe, Joint FAO / World Health Organisation Committee of Food Additives idapereka malingaliro omaliza mu 2007.
Malinga ndi malangizowo, izi siziyenera kuphatikizidwanso pakati pazomwe zimagwiritsidwa ntchito pokonza chakudya cha ana. Izi ndikuti mupewe zovuta zoyipa mwa ana.
Zowonadi, khoma lamatumbo la ana ndilo likhale chiopsezo chachikulu chowonjezerachi.
Icho cha International Agency for Research on Cancer
Kwa International Agency for Research on Cancer, nthambi ya World Health Organisation (WHO); Carrageenan ndiwotheka chifukwa cha khansa yoopsa ya khansa, makamaka yomwe imakulitsa khansa ya m'mawere.
Mankhwala omwe amapangidwa kuchokera ku algae wofiira amaonedwa ndi azachipatala kuti ndiwowopsa kwambiri wowononga anthu.
Kuphatikiza apo, chomalizirachi chakhala chikudziwitsa kwa nthawi yayitali kuti matenda opitilira 100 aanthu samatha kugawanika ndikumwa tsiku lililonse ndikubwereza mobwerezabwereza kwa mankhwalawa.
Chifukwa chake, kugwiritsidwa ntchito kwa chakudya ichi chomwe chimayikidwa pansi pa code E407 ndichofunikira kwambiri pamagulu am'mimba, malinga ndi kafukufuku wotsatira omwe asayansi adachita.
Monga chidziwitso chowonjezera, ma carrageenans onyansidwa, ndiko kuti m'miyeso yotsika ndi mbadwa amadziwika 2B yotchedwa "mwina carcinogenic ya anthu" ndipo 3 imasankhidwa "yopanda chidziwitso chokhudza khansa yake kwa anthu. »Ndi zoopsa zowopsa ndi khansa, makamaka m'mimba ndi International Agency for Research on Cancer.
Malingaliro a European Union
European Union imangovomereza kugwiritsidwa ntchito kwake pa mlingo wochepetsedwa kufika 300 mg/kg pazakudya zina za ana ang'onoang'ono monga jams, jellies ndi marmalades, mkaka wopanda madzi, mafuta opaka pasteurized ndi zonona zofufumitsa.
Mphamvu zenizeni paumoyo
Malinga ndi malingaliro, ma carrageenans amakhudza kwambiri kubereka kwa ma lymphocyte.
Amasokoneza gawo lalikulu lomwe ma cell oyera amathandizira kuwononga matupi akunja monga mabakiteriya kapena kupanga ma antibodies.
Komabe, chakudya carrageenan chimapezeka mumaphikidwe onse amunthu tsiku lililonse omwe amatchedwa organic ndi ochiritsira monga ndiwo zochuluka mchere, mafuta oundana, mafuta, mkaka wosungunuka, sauces, pates ndi nyama zamafuta kapena mowa. ndi ma sodas.
Mwambiri, chophatikiza cha chakudya E407 chitha kufotokozedwera m'njira ziwiri: choyamba, pali imodzi yomwe imakhala ndi ma molekyulu apamwamba omwe amapezeka muzakudya.
Ponena za yachiwiri yomwe ili ndi mawonekedwe a molekyulu yaying'ono, ndi iyi yomwe imagawa malingaliro a omwe ndi enawo; ndipo chomwe koposa zonse chimawopseza ofufuza.
Mtsutso wazaka zambiri
Mwambiri, zawonetsedwa ndi maphunziro ambiri asayansi omwe adatsatana, kangapo m'ma 1960, 1970 ndi 1980s kuti chiwopsezo chaumoyo chilipo ndikumwa zinthu zochokera ku carrageenan (4).
A priori, kuchuluka kwa carrageenan komwe kuli muzakudya zambiri ndikokwanira kumayambitsa kutupa kwa m'mimba, zilonda zam'mimba kapena zotupa zowopsa.
Awa ndi malingaliro a Dr. Joanne Tobacman MD, pulofesa wothandizirana ndi zamankhwala ku University of Illinois ku Chicago.
Mwamwayi, kuchotsa kofiira kofiira kumeneku kumayesedwa mufukufuku lero kuti muwone momwe mankhwala osokoneza bongo amagwirira ntchito.
Pamzerewu wamaganizidwe, mwina ndikofunikira kudziwa kuti carrageenan sikuti imangokhala pazowonjezera zakudya zokha.
Amapezekanso m'zinthu zambiri zomwe sizili zakudya monga zodzikongoletsera, zotsukira m'mano, penti kapenanso zotsitsimutsa mpweya.
Institute of Food Control ku United States (US Food and Drug Administration) ikuzindikira kukhudzidwa kwa carrageenan m'maphunziro osiyanasiyana omwe adachitika.
Popeza carrageenan ali ndi khansa, amalimbikitsa kuti achepetse izi.
Koma vuto ndiloti, sitidziwa kwenikweni kuchuluka kwa carrageenan yomwe timadya patsiku. M'malo mwake, chowonjezera ichi chimapezeka muzakudya zonse zopangidwa.
Misonkhano yowonjezereka ya mabanja ku United States ikukula kuti agule zinthu zawo mwachindunji m’mafamu akomweko.
Zomwe zimakhala zotetezeka komanso zathanzi, mosiyana ndi zinthu zomwe zimagulitsidwa m'masitolo akuluakulu.
Kuphatikiza apo, mabungwe angapo ogula asayina madandaulo mamiliyoni ambiri kuti carrageenan ichotsedwe pakupanga zinthu.
Malinga ndi zomwe tili nazo, mu 2016 mabungwe ogula adapambana mlandu wawo.
Bungwe loyang'anira zinthu zachilengedwe ku United States (5) laganiza zochotsa carrageenan pakupanga zinthu zomwe zimatchedwa organic.
Gwiritsani ntchito zamankhwala
Malinga ndi zaumoyo, ofufuza zamankhwala ndi madotolo pano akuyang'ana kwambiri posonkhanitsa deta kuti amvetsetse bwino kulumikizana pakati pa carrageenan, zakudya ndi matenda am'mimba.
Carrageenan imagwiritsidwa ntchito masiku ano ngati tizilombo tating'onoting'ono tothana ndi matenda opatsirana pogonana.
Zowonadi, kafukufuku wochokera ku American Laboratory of Cellular Oncology ku National Carrageenan Institute ku Bethesda, Maryland wasonyeza izi zowononga ma algae ofiira.
Upangiri wina wazakudya zachilengedwe zomwe zimapezeka ndi zowonjezera za E407 zimaperekedwanso ndi Cornucopia Institute.
Kuyesa zothetsera konkriti
Chida chodziwira nambala yazakudya
Mutu weniweni kwa ogula ambiri ndivuto lomasulira mayina azakudya zomwe nthawi zonse zimaperekedwa ndi manambala.
Zowonadi, anthu ambiri sadziwa mndandanda wazakudya zomwe amameza.
Ndi cholinga chofuna kuthandiza anthu kumvetsetsa bwino ziwerengero za zinthu zomwe zamalizidwa, mwachitsanzo, Gouget Corinne adatulutsa "Zowonjezera pazakudya zowopsa: kalozera wofunikira kuti musiye kudzipha" mu Meyi 2012.
M'buku lino, wolemba yemwe ali ndi zaka zopitilira 12 wazaka zambiri pachakudya cha zowonjezera zowonjezera zakudya kuphatikiza zaka 2 zoperekedwa poyerekeza maphunziro angapo apadziko lonse lapansi, akukuuzani zonse zomwe muyenera kudziwa zazosadziwika zomwe zalembedwa kulongedza.
Chifukwa chake, sipadzakhalanso zinsinsi kapena zinsinsi za zomwe sizinalembedwe pazogulitsa zomwe zitha kugulitsidwa zidzathetsedwa pokupatsani bukhuli lowongolera (6).
Popeza kudziwa zodziwika bwino za zakudya zowonjezera ndi gawo lotsogola ndikukhala ndi bukhu lotsogolera, ndizachilengedwe kwa ogula omwe ali ndi zizindikiro monga kutsekula m'mimba, kutsekula m'mimba kapena kutsekula m'mimba kukhala ndi chidziwitso choyambirira chosiya kukhudza zakudya zomwe zili ndi carrageenan. kuwerenga zolemba zazinthu zopangidwa.
Malangizo ndi zidule
Monga tanenera kale, pali mitundu ingapo ya carrageenan. Amasiyana pamtundu wawo komanso kapangidwe ka mankhwala, chifukwa chake kupezeka kwa zosakaniza zitatu za iota, kappa ndi lambda.
Mwambiri, genera iota yoyamba ndi kappa ndizomwe zimagwiritsidwa ntchito kwambiri kuphika maphikidwe. Mulimonsemo, mlingo womwe mungagwiritse ntchito ndi 2 mpaka 10 magalamu pa kilo.
Kuchokera pamalingaliro awa, chimodzi mwazinthu zowonjezera izi zomwe zimachokera ku red algae ndikuti sichimasungunuka m'madzi ozizira.
Kuti kufalikira kwa ma carrageenans kukhale kosavuta, tikulimbikitsidwa kuti tisungunse chophatikizacho mumadzi ochepa otentha ndikusunthira musanagwiritse ntchito pokonzekera zophikira.
Kuphatikiza apo, chinyengo china chothandiza kwambiri kuwongolera ufa wa E407 mumvula yabwino komanso yapakatikati ndikugwiritsa ntchito kusakaniza ndi dzanja.
Kungakhale kwanzeru kuti aliyense amene ali ndi zodabwitsazi apewe zakudya zomwe zingalumikizane ndi zakumwa izi kuchokera ku algae wofiira.
Kutsiliza
Monga tidakulangizani pamwambapa, werengani zolemba zazinthu mosamala musanagule. Inde, sikophweka kuthera maola ambiri m’masitolo akuluakulu.
Mutha kuchita izi pa intaneti kuchokera kuchipinda chanu. Komanso funsani woyang'anira masitolo akuluakulu omwe mumapitako pafupipafupi kuti akupatseni mndandanda wazinthu zomwe mumagula.
Kuchepetsa kwakukulu kudya kwa zakudya zopangidwa.
Ndizosangalatsa kuti tavumbulutsa kuopsa kwa carrageenan, chowonjezera chakudyachi.
Kondani ndikugawana nkhani yathu.
