Zonse mwazokha, zotsekemera zopanda mphamvu zili zotetezeka, mwinamwake, sizivomerezedwa kuti zigwiritsidwe ntchito. Koma, kugwiritsiridwa ntchito kwa zotsekemera zowonjezera kumatsutsana kwa anthu ena, ngakhale kuti onse amawoneka otetezeka ndipo akhala mbali ya zakudya zambiri za anthu kwazaka zambiri.
Mbiri
Mmodzi mwa akale kwambiri omwe sakhala ndi calorie ndi wokhala ndi saccharin, ndipo ali ndi mbiri yosangalatsa, kuphatikizapo khansa yonyenga.
Saccharin inapezedwa mu 1879 ndipo idagwiritsidwa ntchito kumayambiriro kwa zaka za zana la 20 monga shuga m'malo mwa odwala shuga. Saccharin siwotchuka ngati kale, koma imapezekabe ngati zotsekemera zopangidwa ndi ufa. Chifukwa chake saccharin ndi yotsika kwambiri mu makilogalamu ndikuti nthawi mazana 200 mpaka 700 ndi okoma kuposa shuga pa tebulo, kotero zochepa kwambiri zimafunika.
Kafukufuku Woyamba
Saccharin ili ndi mbiri yakale ya ntchito yotetezedwa ndi anthu. Koma, kafukufuku wina wofukufuku amene adafalitsidwa kumayambiriro kwa zaka za m'ma 1970 adanena kuti zambiri za saccharin zinayambitsa zotupa za chikhodzodzo m'mphumba. Zotsatirazo zinapangitsa kuti chisankho cha Food and Drug Administration chisamalowetseketsa zokoma, koma m'malo mwake, United States Congress inapereka lamulo lofuna kuti liwu lochenjeza likhale loperekedwa pa zakudya zilizonse zomwe zili ndi saccharin.
"Kugwiritsira ntchito mankhwalawa kungakhale koopsa pa thanzi lanu. Chigulangachi chili ndi mankhwala opangira khansa m'matumba a laboratory."
Ofufuza ankafuna kudziwa zambiri zokhudza momwe saccharin ingayambitsire khansa. Koma pamene adakumba kwambiri, adapeza njira yowonetsera chiberekero m'mimba yamphongo sizinali za biology - ziphuphu zamphongo zimapanga mapuloteni ena omwe sapezeka m'thupi la munthu.
Popeza panalibe chifukwa chokhulupirira saccharin chikhoza kubweretsa khansara mwa anthu, icho chinachotsedwa pa mndandanda wa zinthu zomwe zimayambitsa khansara mwa anthu, ndipo lamulo lofunira lemba lochenjeza linachotsedwa.
Zogulitsa zomwe zimagulitsidwa ku United States zomwe zili ndi saccharin sizifunikanso kuti zikhale ndi malemba ochenjeza.
Ntchito Yamakono
Nsembeyi ikhoza kukhululukidwa ngati wodwala khansa, koma siigwiritsidwe ntchito mobwerezabwereza lero - chifukwa chakuti okoma atsopano monga aspartame ndi Sucralose alibe ululu wowawa pambuyo pake.
Sweet'N Mpweya wochepa umapezeka m'masitolo ambiri, ndipo amapezeka ngati chogwiritsira ntchito zakudya zochepa. Soda ya zakudya yotchedwa TaB imakondwera ndi saccharin, koma imakhala ndi aspartame.
