I-methylcellulose sisongezo sokutya esiqhelekileyo. Yenziwe kwi-cellulose yendalo ngokuguqulwa kweekhemikhali. Inozinzo oluhle, i-gelling kunye ne-thickening properties kwaye isetyenziswa ngokubanzi kwishishini lokutya. Njengento eyenziwe yalungiswa, ukhuseleko lwalo ekutyeni kudala luyinkxalabo.
1. Iipropati kunye nemisebenzi ye-methylcellulose
Ubume bemolekyuli ye-methylcellulose isekelwe kwiβIyunithi ye-1,4-glucose, eyenziwa ngokutshintshela amanye amaqela e-hydroxyl kunye namaqela e-methoxy. I-soluble emanzini abandayo kwaye inokwenza i-gel eguqulwayo phantsi kweemeko ezithile. Inokuqina okulungileyo, i-emulsification, ukumiswa, ukuzinza kunye neempawu zokugcina amanzi. Le misebenzi yenza ukuba isetyenziswe ngokubanzi kwisonka, kwi-pastries, iziphuzo, iimveliso zobisi, ukutya okufriziwe kunye namanye amasimi. Ngokomzekelo, inokuphucula ukuthungwa kwentlama kunye nokulibazisa ukuguga; ekutyeni okukhenkcezisiweyo, inokuphucula ukuxhathisa umkhenkce.
Ngaphandle kwemisebenzi yayo eyahlukeneyo, i-methylcellulose ngokwayo ayifuntshwa okanye isetyenziswe emzimbeni womntu. Emva kokungeniswa, ngokuyininzi ikhutshwe kwi-digestive tract kwifom engabonakaliyo, eyenza impembelelo yayo ngqo kumzimba womntu ibonakala ilinganiselwe. Nangona kunjalo, olu phawu luye lwavusa inkxalabo yabantu yokuba ukuthatha kwayo ixesha elide kunokuchaphazela impilo yamathumbu.
2. Uvavanyo lwetyhefu kunye nezifundo zokhuseleko
Izifundo ezininzi ze-toxicological zibonise ukuba i-methylcellulose ine-biocompatibility efanelekileyo kunye ne-toxicity ephantsi. Iziphumo zovavanyo lwetyhefu ebukhali zibonise ukuba i-LD50 yayo (idosi ebulalayo ephakathi) yayiphezulu kakhulu kunexabiso elisetyenziswa kwizongezo zokutya eziqhelekileyo, ebonisa ukhuseleko oluphezulu. Kuvavanyo lwexesha elide lwetyhefu, iimpuku, iimpuku kunye nezinye izilwanyana azizange zibonise ukusabela okungalunganga phantsi kokutya kwexesha elide kwiidosi eziphezulu, kubandakanya nemingcipheko efana ne-carcinogenicity, i-teratogenicity kunye netyhefu yokuzala.
Ukongezelela, umphumo we-methylcellulose kumathumbu omntu ufundwe ngokubanzi. Ngenxa yokuba ayigaywanga kwaye ifakwe, i-methylcellulose inokunyusa umthamo we-stool, ikhuthaze i-intestinal peristalsis, kwaye ineenzuzo ezithile ekupheliseni ukuqhina. Kwangaxeshanye, ayivundisi yintyatyambo yamathumbu, inciphisa umngcipheko weflatulence okanye iintlungu zesisu.
3. Imimiselo kunye nemimiselo
Ukusetyenziswa kwe-methylcellulose njengesongezo sokutya kulawulwa ngokungqongqo kwihlabathi jikelele. Ngokutsho kovavanyo lweKomidi yeNgcali eDityanisiweyo kwiZongezo zokutya (JECFA) phantsi koMbutho wokuTya kunye nezoLimo weZizwe eziManyeneyo (i-FAO) kunye noMbutho wezeMpilo weHlabathi (i-WHO), ukutya okuvumelekileyo kwimihla ngemihla (ADI) ye-methylcellulose "ayichazwanga. ", ebonisa ukuba kukhuselekile ukusebenzisa kwidosi ecetyiswayo.
EUnited States, i-methylcellulose idweliswe njengeyona nto yamkelwa ngokubanzi njengekhuselekile (GRAS) yi-US Food and Drug Administration (FDA). Kwi-European Union, ihlelwa njenge-e461 yokutya, kwaye ukusetyenziswa kwayo okuphezulu ekutyeni okuhlukeneyo kuchazwe ngokucacileyo. E-China, ukusetyenziswa kwe-methylcellulose kulawulwa "nguMgangatho weSizwe woKhuseleko loKutya oLongezelelweyo lokuSebenza" (i-GB 2760), efuna ukulawulwa ngokungqongqo kwi-dosage ngokohlobo lokutya.
4. Iingqwalasela zokhuseleko kwizicelo ezibonakalayo
Nangona ukhuseleko lulonke lwe-methylcellulose luphezulu, ukusetyenziswa kwayo ekutyeni kusafuna ukuhoywa kwezi ngongoma zilandelayo:
Idosi: Ukongezwa ngokugqithisileyo kunokutshintsha ukuthungwa kokutya kwaye kuchaphazele umgangatho wokuziva; kwangaxeshanye, ukuthathwa ngokugqithisileyo kwezinto ezinefayibha ephezulu kunokubangela ukuqunjelwa okanye ukungonwabi kokutya.
Abantu ekujoliswe kubo: Kubantu abanomsebenzi obuthathaka wamathumbu (njengabakhulileyo okanye abantwana abancinci), amaxabiso aphezulu e-methylcellulose angabangela ukungahambi kakuhle ngexesha elifutshane, ngoko kufuneka kukhethwe ngokuqaphela.
Ukusebenzisana nezinye izithako: Kwezinye iifomthi zokutya, i-methylcellulose ingaba nefuthe le-synergistic kunye nezinye izongezo okanye izithako, kwaye iziphumo zabo ezidibeneyo kufuneka ziqwalaselwe.
5. Isishwankathelo kunye ne-Outlook
Nje,i-methylcellulose sisongezo sokutya esikhuselekileyo nesisebenzayo esingayi kubangela ingozi enkulu kwimpilo yabantu ngaphakathi koluhlu olufanelekileyo lokusetyenziswa. Iimpawu zayo ezingenakufunxa zenza ukuba izinzile kwi-digestive tract kwaye inokuzisa izibonelelo ezithile zempilo. Nangona kunjalo, ukuze kuqinisekiswe ngakumbi ukhuseleko lwayo ekusebenziseni ixesha elide, kuyimfuneko ukuqhubeka nokunikela ingqalelo kwizifundo ezifanelekileyo ze-toxicological kunye nedatha yesicelo esisebenzayo, ngakumbi impembelelo yayo kubantu abakhethekileyo.
Ngophuhliso lweshishini lokutya kunye nokuphuculwa kwemfuno yabathengi yomgangatho wokutya, umda wokusetyenziswa kwe-methylcellulose unokwandiswa ngakumbi. Kwixesha elizayo, izicelo ezintsha ezithe chatha kufuneka zijongwe kwisiseko sokuqinisekisa ukhuseleko lokutya ukuzisa ixabiso elikhulu kushishino lokutya.
