Methylceluplose yindawo yokutya okuqhelekileyo. Yenziwe kwi-selupese yendalo ngokulungiswa kweekhemikhali. Inozinzo olulungileyo, ukulungisa kunye neepropathi ezinkulu kwaye isetyenziswa ngokubanzi kwishishini lokutya. Njengezinto eziguqulweyo eziguqulweyo, ukhuseleko lwayo lokutya kudala luyinkxalabo.
1. Iipropathi kunye nemisebenzi ye-methylcelgalose
Ubume bemolekyuli be-methylcelgalose busekwe kwiβ-1,4-Iyunithi ye-Glucose, enziwa ngokutshintsha amaqela e-hydroxyl ngamasebe e-AFGESS. Inyibilikisa emanzini ebandayo kwaye inokwenza i-gel eguqukayo phantsi kweemeko ezithile. Inesisu esihle, ukwenziwa kwe-sulsation, ukunqunyanyiswa, izizwe kunye nezakhiwo zokugcina amanzi. Le misebenzi yenza ukuba isetyenziswe ngokubanzi ngesonka, i-pastries, i-goregeges, iimveliso zobisi, ukutya okuthandekayo kunye namanye amasimi. Umzekelo, inokuphucula ukuqulunqwa kwenhlama kunye nokulibazisa ukwaluphala; Ngokutya okutyayo, kunokuphucula ukumelana nokunganyangeki.
Ngaphandle kwemisebenzi yalo eyahlukeneyo, iMethylcealsulose ayifuneki okanye ifakwe ithebhu emzimbeni womntu. Emva kokungeniswa, kuchithwa ikakhulu ngephecana lokugaya kwindawo engalunganga, eyenza ifuthe ngqo kumzimba womntu libonakala lilinganiselwe. Nangona kunjalo, olu phawu luvuselele inkxalabo yabantu ukuba ukukhulelwa kwexesha elide kunokuchaphazela impilo yamathumbu.
I-2. Uvavanyo lwetyhefu kunye nezifundo zoKhuseleko
Izifundo zetyhefu ezininzi zibonise ukuba i-methylcelcelceltulose ine-biomatining elungileyo kunye netyhefu esezantsi. Iziphumo zeemvavanyo zetyhefu ezinamafutha zibonisa ukuba i-LD50 (idosi ye-Inia ye-Inian) yayiphezulu kunenani elisetyenziswa kwizixa ezisetyenzisiweyo kwizinto zokutya eziqhelekileyo, zibonisa ukhuseleko oluphezulu. Kwiimvavanyo zexesha elide kakhulutyhefu, iigundane, iimpuku kunye nezinye izilwanyana azikhange zibonise ukuphendula okukhulu phantsi kweedosi zexesha elide, kubandakanya umngcipheko njenge-carcinogenity, i-teratogenisity kunye netyhefu.
Ukongeza, isiphumo se-methylcelculose kwithuna lomntu sifundiswe ngokubanzi. Kuba ayiphenjwa kwaye ingenelwe, iMethylcelsulose inokunyusa ivolumu yesitulo, ikhuthaze i-peristals yamathumbu, kwaye inezibonelelo ezithile ekunciphiseni ukuqhutywa. Kwangelo xesha, akuzange kubiwe nge-bistinaal flora, ukunciphisa umngcipheko wokuqina okanye isisu.
I-3. Imigaqo kunye nemilinganiselo
Ukusetyenziswa kwe-methylceluplose njengesongezo lokutya kulawulwa ngokungqongqo kwihlabathi liphela. Ngokovavanyo lweKomiti yeNgeniso edibeneyo kwi-Sopuvaltives yokutya (i-Jecfa) phantsi kombutho wokutya nezoLimo kwiZizwe eziManyeneyo (i-FAO) kunye noMbutho wezeMpilo weHlabathi (i-ADI) ye-methylcelculose "ayichazwanga ", ebonisa ukuba kukhuselekile ukusebenzisa ngaphakathi komthamo ocetyiswayo.
E-United States, i-methylcelcelsulose idweliswe njengendawo evunyiweyo njengeyona nto ikhuselekileyo (GRAs) i-US ngokutya kunye nolawulo lweziyobisi (i-FDA). Kwi-European Union, ihlelwe njenge-E461 ye-E461, kunye nokusetyenziswa kwayo okuphezulu kokutya okwahlukileyo kucacisiwe ngokucacileyo. E China, ukusetyenziswa kwe-methylcelculose ilawulwa yi "Foodland yokhuseleko lokutya okuphezulu kokutya" (i-GB 2760), efuna ulawulo olungqongqo lomthamo ngohlobo lokutya.
4. Ukuqwalaselwa kukhuseleko kwizicelo ezisebenzayo
Nangona ukhuseleko olupheleleyo lwe-methylcelculose luphezulu, ukusetyenziswa kwayo kukutya kusafuneka kuthi kunyanzeleke ukuba inikele ingqalelo kwezi ngongoma zilandelayo:
I-Dosage: Ukongeza okugqithisileyo kunokutshintsha ukwenziwa kokutya kwaye kuchaphazele umgangatho weemvakalelo; Kwangelo xesha, ukutya okugqithisileyo kwezinto eziphezulu ze-fiber kunokubangela ukungakhathali okanye ukudakumba.
Inani lethagethi: Ngobantu abathobekileyo nomsebenzi obuthathaka ongenamandla (njengabantwana abadala okanye abantwana abaselula), iidosi eziphezulu zeMethylceLceLcelsulose zinokubangela ukungcungcutheka kwixesha elifutshane, kuya kufuneka zikhethwe ngononophelo.
Unxibelelwano kunye nezinye izithako: Kwimisebenzi ethile yokutya, iMethylcealsulose inokuba nefuthe lokunyelisa kunye nezinye izithako, kwaye iziphumo zazo ezidibeneyo kufuneka ziqwalaselwe.
5. Isishwankathelo kunye ne-Outlook
Nje,methylceluplose luphawu olukhuselekileyo nolusebenzayo olungathethekiyo olungayi kubangela ingozi enkulu kwimpilo yabantu ngaphakathi kuluhlu olusengqiqweni. Iipropathi zayo ezingezizo ezingezizo zenza ukuba zizinzile kwiphecana lokugaya ukutya kwaye linokuzisa izibonelelo ezithile zempilo. Nangona kunjalo, ukwenzela ukuqhubeka nokhuseleko lwayo kukhuseleko lwexesha elide, kuyimfuneko ukuqhubeka nokunikela ingqalelo kwizifundo zetyhefu ezifanelekileyo kunye nedatha yesicelo esebenzayo, ngakumbi ifuthe labantu abakhethekileyo.
Ngokuphuhliswa kwemveliso yokutya kunye nokuphuculwa kwemfuno yabathengi kumgangatho wokutya, ubungakanani bokusetyenziswa kwe-methylcelculose kunokwandiswa ngakumbi. Kwixesha elizayo, izicelo ezininzi ezinobuchule kufuneka ziphononongwe kwisakhiwo sokuqinisekisa ukhuseleko lokutya ukuzisa ixabiso elikhulu kwishishini lokutya.
