Methylcellulose chinhu chakajairika chekuwedzera chikafu. Inogadzirwa kubva kune yakasikwa cellulose kuburikidza nekugadziriswa kwemakemikari. Iine kugadzikana kwakanaka, gelling uye thickening zvivakwa uye inoshandiswa zvakanyanya muindasitiri yezvekudya. Sechinhu chakagadziridzwa chakagadziridzwa, kuchengetedzwa kwayo muchikafu kwagara kuri kunetseka.
1. Zvinhu uye mabasa emethylcellulose
Iyo molecular chimiro che methylcellulose yakavakirwa paneβ-1,4-glucose unit, iyo inoumbwa nekutsiva mamwe mapoka e-hydroxyl nemapoka e-methoxy. Inonyungudika mumvura inotonhora uye inogona kuumba gel inogadziriswa pasi pemamwe mamiriro ezvinhu. Iyo ine yakanaka thickening, emulsification, kumiswa, kugadzikana uye kuchengetedza mvura. Aya mabasa anoita kuti zvishandiswe zvakanyanya muchingwa, makeke, zvinwiwa, zvigadzirwa zvemukaka, chikafu chakaomeswa uye mimwe minda. Semuenzaniso, inogona kuvandudza kuumbwa kwehupfu uye kunonoka kukwegura; muzvikafu zvakaomeswa nechando, zvinogona kuvandudza kushomeka kwechando.
Pasinei nemabasa ayo akasiyana-siyana, methylcellulose pachayo haina kunyudzwa kana kugadzirwa mumuviri wemunhu. Mushure mekudya, inonyanya kubudiswa kuburikidza negumbo rekudya mune fomu isina kusvibiswa, iyo inoita kuti maitiro ayo akananga pamuviri wemunhu aite seashoma. Zvakadaro, hunhu uhu hwakamutsawo kunetseka kwevanhu kuti kutora kwayo kwenguva refu kunogona kukanganisa hutano hwematumbo.
2. Toxicological evaluation uye zvidzidzo zvekuchengetedza
Multiple toxicological zvidzidzo zvakaratidza kuti methylcellulose ine yakanaka biocompatibility uye yakaderera chepfu. Mhedzisiro yeacute toxicity bvunzo yakaratidza kuti LD50 yayo (yepakati inouraya dose) yaive yakakwira zvakanyanya kupfuura huwandu hunoshandiswa mune zvakajairwa zvekudya zvinowedzera, zvichiratidza kuchengetedzwa kwakanyanya. Mukuyedzwa kwehupfu hwenguva refu, makonzo, mbeva nedzimwe mhuka hadzina kuratidza kusarudzika kwakashata pasi pekudya kwenguva refu pamitengo yakakwira, kusanganisira njodzi dzakadai secarcinogenicity, teratogenicity uye huturu hwekubereka.
Pamusoro pezvo, mhedzisiro yemethylcellulose padumbu remunhu yakadzidzwawo zvakanyanya. Nemhaka yokuti haina kugayiwa uye kunyura, methylcellulose inogona kuwedzera stool volume, kukurudzira intestinal peristalsis, uye ine zvimwe zvikomborero mukuderedza kuvimbiswa. Panguva imwecheteyo, haina kuviriswa nemaruva emukumbo, kuderedza njodzi ye flatulence kana kurwadziwa mudumbu.
3. Mitemo nemitemo
Kushandiswa kwemethylcellulose sechikafu chekuwedzera kunodzorwa pasi rese. Zvinoenderana nekuongororwa kweJoint Expert Committee yeFood Additives (JECFA) pasi peFood and Agriculture Organisation yeUnited Nations (FAO) neWorld Health Organisation (WHO), kudyiwa kwezuva nezuva (ADI) kwemethylcellulose "haina kutaurwa. ", zvichiratidza kuti zvakachengeteka kushandisa mukati meiyo dosi yakakurudzirwa.
MuUnited States, methylcellulose yakanyorwa sechinhu chinowanzo zivikanwa seyakachengeteka (GRAS) chinhu neUS Food and Drug Administration (FDA). MuEuropean Union, inorondedzerwa sekuwedzera kwekudya E461, uye kushandiswa kwayo kwakanyanya mukudya kwakasiyana kunotsanangurwa zvakajeka. MuChina, kushandiswa kwemethylcellulose kunodzorwawo ne "National Food Safety Standard Food Additive Usage Standard" (GB 2760), iyo inoda kudzora kwakasimba kwedosi zvinoenderana nerudzi rwechikafu.
4. Mafungiro ekuchengetedza mune zvinoshanda zvekushandisa
Kunyangwe kuchengetedzwa kwese kwemethylcellulose kwakakwira, kushandiswa kwayo muchikafu kuchiri kufanira kutarisisa kune anotevera mapoinzi:
Chiyero: Kuwedzera kuwedzera kunogona kushandura kuumbwa kwechikafu uye kukanganisa hunhu hwekunzwa; panguva imwecheteyo, kunwa zvakanyanya kwe-high-fiber zvinhu zvinogona kukonzera kuputika kana kusagadzikana kwekudya.
Chinangwa chevanhu: Kune vanhu vane hutumbu husina simba (zvakadai sevakwegura kana vana vaduku), madhasi makuru emethylcellulose anogona kukonzera indigestion munguva pfupi, saka inofanira kusarudzwa nekuchenjerera.
Kudyidzana nezvimwe zvinongedzo: Mune mamwe magadzirirwo echikafu, methylcellulose inogona kunge iine synergistic mhedzisiro nezvimwe zvinowedzera kana zvinongedzo, uye mhedzisiro yavo yakasanganiswa inoda kutariswa.
5. Pfupiso uye Outlook
Kazhinji,methylcellulose chinhu chakachengeteka uye chinoshanda chekuwedzera chekudya icho chisingazokonzerese kukuvadza kwakakosha kuhutano hwevanhu mukati mehuwandu hunoenderana hwekushandisa. Izvo zvisingabatike zvimiro zvinoita kuti zvigadzikane mudumbu rekudya uye zvinogona kuunza humwe hutano hunobatsira. Nekudaro, kuitira kuti uwedzere kuve nechokwadi chekuchengetedza kwayo mukushandiswa kwenguva refu, zvinodikanwa kuramba uchiteerera kune yakakodzera toxicological zvidzidzo uye inoshanda data data, kunyanya kukanganisa kwayo kune vanhu vakasiyana.
Nekuvandudzwa kweindasitiri yechikafu uye nekuvandudzwa kwezvinodiwa nevatengi zvemhando yechikafu, huwandu hwekushandiswa kwemethylcellulose hunogona kuwedzerwa. Mune ramangwana, mamwe maapplication matsva anofanirwa kuongororwa pachitariswa chekuona kuchengetedzwa kwechikafu kuunza kukosha kukuru kuindasitiri yezvekudya.
