Methylcellulose ƙari ne na kowa abinci. An yi shi daga cellulose na halitta ta hanyar gyare-gyaren sinadarai. Yana da kyau kwanciyar hankali, gelling da thickening Properties da aka yadu amfani a cikin abinci masana'antu. A matsayin wani abu da aka gyara ta wucin gadi, amincin sa a cikin abinci ya daɗe yana damuwa.
1. Kayayyaki da ayyuka na methylcellulose
Tsarin kwayoyin halitta na methylcellulose ya dogara ne akanβ-1,4-glucose unit, wanda aka kafa ta maye gurbin wasu kungiyoyin hydroxyl tare da kungiyoyin methoxy. Yana da narkewa a cikin ruwan sanyi kuma yana iya samar da gel mai jujjuyawa a ƙarƙashin wasu yanayi. Yana yana da kyau thickening, emulsification, dakatar, kwanciyar hankali da kuma ruwa riƙe Properties. Waɗannan ayyukan sun sa ana amfani da shi sosai a cikin burodi, kek, abubuwan sha, samfuran kiwo, abinci daskararre da sauran filayen. Misali, zai iya inganta yanayin kullu da jinkirta tsufa; a cikin abincin da aka daskararre, zai iya inganta juriya na daskare.
Duk da ayyuka daban-daban, methylcellulose kanta ba ta shiga jikin mutum ko kuma ta koma cikin jiki. Bayan an sha, an fi fitar da shi ta hanyar narkewar abinci a cikin wani nau'i marar rube, wanda ke sa tasirinsa kai tsaye ga jikin ɗan adam ya zama iyakance. Duk da haka, wannan siffa ta kuma tada hankalin mutane cewa shanta na dogon lokaci na iya shafar lafiyar hanji.
2. Binciken toxicological da nazarin aminci
Yawancin bincike na toxicological sun nuna cewa methylcellulose yana da kyau biocompatibility da low toxicity. Sakamakon gwaje-gwajen guba mai tsanani ya nuna cewa LD50 (tsakiyar kisa) ya fi yawan adadin da aka yi amfani da shi a cikin kayan abinci na yau da kullun, yana nuna babban aminci. A cikin gwaje-gwaje masu guba na dogon lokaci, berayen, mice da sauran dabbobi ba su nuna mummunan halayen ba a ƙarƙashin ciyarwar dogon lokaci a manyan allurai, gami da haɗari irin su carcinogenicity, teratogenicity da gubar haihuwa.
Bugu da kari, an kuma yi nazari sosai kan tasirin methylcellulose akan hanjin dan adam. Saboda ba a narkar da shi ba kuma yana sha, methylcellulose na iya ƙara ƙarar stool, inganta peristalsis na hanji, kuma yana da wasu fa'idodi na kawar da maƙarƙashiya. A lokaci guda kuma, ba a yin fermented ta flora na hanji, rage haɗarin flatulence ko ciwon ciki.
3. Ka'idoji da ka'idoji
Amfani da methylcellulose a matsayin ƙari na abinci yana da ƙayyadaddun tsari a duk duniya. Bisa kididdigar da kwamitin ƙwararrun ƙwararrun Ƙwararrun Ƙwararrun Abinci (JECFA) suka yi a ƙarƙashin Hukumar Abinci da Aikin Noma ta Majalisar Dinkin Duniya (FAO) da Hukumar Lafiya ta Duniya (WHO), ba a kayyade yawan abinci na yau da kullum (ADI) na methylcellulose ba. ", yana nuna cewa yana da aminci don amfani a cikin adadin da aka ba da shawarar.
A cikin Amurka, an jera methylcellulose azaman abin da Hukumar Abinci da Magunguna ta Amurka (FDA) ta amince da ita azaman amintaccen abu (GRAS). A cikin Tarayyar Turai, an rarraba shi azaman ƙari na abinci E461, kuma an ƙayyade iyakar amfani da shi a cikin abinci daban-daban. A kasar Sin, ana kuma tsara amfani da methylcellulose ta "Ka'idar Amfani da Kariyar Abinci ta Ƙasa" (GB 2760), wanda ke buƙatar tsauraran matakan sarrafawa gwargwadon nau'in abinci.
4. La'akari da aminci a aikace-aikace masu amfani
Kodayake amincin methylcellulose gabaɗaya yana da girma, aikace-aikacen sa a cikin abinci har yanzu yana buƙatar kula da abubuwan da ke gaba:
Sashi: Ƙari mai yawa na iya canza yanayin abinci kuma ya shafi ingancin ji; a lokaci guda, yawan cin abinci mai yawan fiber na iya haifar da kumburi ko rashin jin daɗi na narkewa.
Yawan jama'a: Ga mutane masu rauni na hanji (kamar tsofaffi ko yara ƙanana), yawan adadin methylcellulose na iya haifar da rashin narkewa a cikin gajeren lokaci, don haka ya kamata a zaba tare da taka tsantsan.
Yin hulɗa tare da wasu sinadaran: A cikin wasu nau'o'in abinci, methylcellulose na iya samun tasiri mai tasiri tare da wasu additives ko sinadaran, kuma ana buƙatar la'akari da tasirin su.
5. Summary da Outlook
Gabaɗaya,methylcellulose ƙari ne mai aminci kuma mai inganci wanda ba zai haifar da babbar illa ga lafiyar ɗan adam ba tsakanin kewayon amfani. Abubuwan da ba za su iya sha ba sun sa ya zama ɗan kwanciyar hankali a cikin tsarin narkewa kuma yana iya kawo wasu fa'idodin kiwon lafiya. Koyaya, don ƙara tabbatar da amincin sa a cikin amfani na dogon lokaci, ya zama dole a ci gaba da mai da hankali kan nazarin toxicological masu dacewa da bayanan aikace-aikacen aikace-aikacen, musamman tasirinsa akan al'ummomi na musamman.
Tare da haɓaka masana'antar abinci da haɓaka buƙatun masu amfani don ingancin abinci, ƙimar amfani da methylcellulose na iya ƙara faɗaɗa. A nan gaba, ya kamata a bincika ƙarin sabbin aikace-aikace akan yanayin tabbatar da amincin abinci don kawo ƙima ga masana'antar abinci.
