Kodi chingamu cha cellulose ndi chowopsa kwa anthu?

Cellulose chingamu, yomwe imadziwikanso kuti carboxymethyl cellulose (CMC), ndi chowonjezera chazakudya chomwe chimagwiritsidwa ntchito ngati thickener, stabilizer, and emulsifier muzakudya zosiyanasiyana zokonzedwa, zodzoladzola, ndi mankhwala. Amachokera ku cellulose, polima yachilengedwe yomwe imapanga makoma a maselo a zomera, ndipo amasinthidwa ndi mankhwala kuti apange chinthu chofanana ndi chingamu.

Pakhala pali nkhawa za chitetezo cha chingamu cha cellulose m'zaka zaposachedwa, pomwe kafukufuku wina akuwonetsa kuti zitha kukhala ndi zotsatira zoyipa pa thanzi la munthu. M'nkhaniyi, tifufuza kafukufuku wa chingamu cha cellulose ndi zomwe zingawononge thanzi laumunthu.

Maphunziro a Toxicity pa Cellulose Gum

Pakhala pali maphunziro angapo okhudza kawopsedwe wa chingamu cha cellulose, nyama ndi anthu. Zotsatira za kafukufukuyu zasakanizidwa, ndipo ena amati chingamu cha cellulose ndi chotetezeka kuti chigwiritsidwe ntchito, pomwe ena adadzutsa nkhawa za kuopsa kwake.

Kafukufuku wina wofalitsidwa mu Journal of Food Science and Technology mu 2015 anapeza kuti chingamu cha cellulose chinali chotetezeka kuti chigwiritsidwe ntchito ndi makoswe, ngakhale pa mlingo waukulu. Kafukufukuyu adapeza kuti makoswe amadyetsa zakudya zomwe zimakhala ndi chingamu cha 5% kwa masiku a 90 sanawonetse zizindikiro za poizoni kapena zotsatira zoyipa zaumoyo.

Kafukufuku wina yemwe adasindikizidwa mu Journal of Toxicology and Environmental Health mu 2017 adawunika kawopsedwe ka chingamu cha cellulose mu makoswe ndipo sanapeze umboni wa kawopsedwe kapena zotsatira zoyipa, ngakhale atamwa mpaka 5% yazakudya za nyama.

Komabe, kafukufuku wina wadzetsa nkhawa za chitetezo cha chingamu cha cellulose. Kafukufuku wofalitsidwa mu Journal of Occupational Health mu 2005 anapeza kuti kupuma kwa cellulose chingamu kumayambitsa zizindikiro za kupuma kwa ogwira ntchito kumalo opangira ma cellulose chingamu. Kafukufukuyu adawonetsa kuti kupuma kwa chingamu cha cellulose kungayambitse kupsa mtima komanso kutupa, ndipo adalimbikitsa ogwira ntchito kuti atetezedwe kuti asavutike.

Kafukufuku yemwe adasindikizidwa mu International Journal of Toxicology mu 2010 adapeza kuti chingamu cha cellulose chinali genotoxic mu ma lymphocyte amunthu, omwe ndi maselo oyera amagazi omwe amagwira ntchito yofunika kwambiri pachitetezo cha mthupi. Kafukufukuyu adapeza kuti kukhudzana ndi kuchuluka kwa chingamu cha cellulose kumayambitsa kuwonongeka kwa DNA ndikuwonjezera kuchuluka kwa zolakwika za chromosomal mu ma lymphocyte.

Kafukufuku wina wofalitsidwa mu Journal of Applied Toxicology mu 2012 adapeza kuti chingamu cha cellulose chinali poizoni m'maselo a chiwindi cha munthu mu vitro, zomwe zimayambitsa kufa kwa maselo ndi kusintha kwina kwa ma cell.

Ponseponse, umboni wa kawopsedwe wa chingamu cha cellulose ndi wosakanikirana. Ngakhale kafukufuku wina sanapeze umboni wa kawopsedwe kapena zotsatira zoyipa za thanzi, ena anenapo za kuopsa kwake, makamaka pankhani ya kupuma ndi ma genetic.

Zomwe Zingatheke Zaumoyo Zaumoyo wa Cellulose Gum

Ngakhale umboni wokhudzana ndi kawopsedwe ka chingamu wa cellulose usakanizidwa, pali ngozi zingapo zomwe zingachitike chifukwa chogwiritsa ntchito zakudya ndi zinthu zina.

Chiwopsezo chimodzi chomwe chingakhalepo ndi kuthekera kwa kupsa mtima komanso kutupa, makamaka kwa ogwira ntchito omwe ali pachiwopsezo chachikulu cha fumbi la chingamu la cellulose. Ogwira ntchito m'mafakitale monga kupanga mapepala ndi kukonza zakudya akhoza kukhala pachiwopsezo chokhudzidwa ndi fumbi la cellulose chingamu, zomwe zingayambitse zizindikiro za kupuma monga kutsokomola, kupuma movutikira, komanso kupuma movutikira.

Chiwopsezo china cha chingamu cha cellulose ndi kuthekera kwake kupangitsa kuwonongeka kwa DNA komanso kusakhazikika kwa chromosomal, monga momwe kafukufuku wafotokozera pamwambapa. Kuwonongeka kwa DNA ndi zovuta za chromosomal zitha kuonjezera chiopsezo cha khansa ndi matenda ena obadwa nawo.

Kuonjezera apo, kafukufuku wina wasonyeza kuti chingamu cha cellulose chingasokoneze kuyamwa kwa zakudya m'matumbo, makamaka mchere monga calcium, iron, ndi zinc. Izi zitha kubweretsa kusokonekera kwa michere iyi komanso zovuta zokhudzana ndi thanzi.
