Kupu Whakataki

Ko te konutai carboxymethyl cellulose (CMC) he taapiri kai e whakamahia ana hei whakapai ake i te kakano, te pumau, me te oranga o nga momo momo hua kai. Ko te CMC he paura ma, he hongi, he kore reka i ahu mai i te cellulose, te waahanga matua o nga pakitara tipu. He polysaccharide, te tikanga he maha nga ngota ngota huka e hono tahi ana. Ka whakamahia te CMC ki nga momo momo kai, tae atu ki te aihikirimi, te ranu, te kakahu, me nga taonga tunu.

Hītori

I whakawhanakehia tuatahitia a CMC i te timatanga o te rau tau 1900 e tetahi tohunga kemu Tiamana, a Dr. Karl Schardinger. I kitea e ia ma te rongoa i te cellulose me te whakakotahitanga o te konutai hydroxide me te waikawa monochloroacetic, ka taea e ia te hanga i tetahi puhui hou e memeha ake ana i te wai i te cellulose. I tapaina tenei puhui hou he carboxymethyl cellulose, he CMC ranei.

I nga tau 1950, i whakamahia tuatahitia te CMC hei taapiri kai. I whakamahia hei whakamaroke me te whakapumau i nga ranu, nga kakahu, me etahi atu hua kai. Mai i tera wa, kua noho te CMC hei taapiri kai rongonui na tona kaha ki te whakapai ake i te kakano, te pumau, me te oranga o nga hua kai.

Matū

Ko te CMC he polysaccharide, ko te tikanga he maha nga ngota ngota huka e hono tahi ana. Ko te waahanga matua o te CMC ko te cellulose, he mekameka roa o nga ngota ngota ngota huka. Ina tukuna te cellulose ki te whakakotahitanga o te konutai waikawa me te waikawa monochloroacetic, ka hanga he carboxymethyl cellulose. Ko tenei tukanga e mohiotia ana ko te carboxymethylation.

Ko te CMC he paura ma, he hongi, he horekau karekau he wairewa i roto i te wai matao me te wai wera. He taonga kore-paitini, kore-allergenic, me te kore e whakapataritari, he haumaru mo te kai tangata.

Mahi

Ka whakamahia te CMC ki nga momo hua kai hei whakapai ake i te kakano, te pumau, me te oranga o te papa. Ka whakamahia hei maatete ki te whakaputa i nga hua kai he kakano kirikiri me te whakapumau kia kore e wehe, e pahuatia ranei. Ka whakamahia ano te CMC hei whakaehunga hei awhina i te whakakotahitanga o te hinu me te wai.

I tua atu, ka whakamahia te CMC ki te aukati i te hanga tio tio i roto i nga kai reka tio, penei i te aihikirimi. Ka whakamahia hoki hei whakapai ake i te kakano o nga taonga tunu, penei i te keke me te pihikete.

Ture

Ko te CMC kei te whakahaeretia e te Kai me te Taakaro Whakahaere (FDA) i te United States. Kua whakaritea e te FDA te taumata teitei o te whakamahi mo te CMC ki nga hua kai. Ko te taumata teitei o te whakamahinga ko te 0.5% ma te taumaha.

Whakamutunga

Ko te konutai carboxymethyl cellulose (CMC) he taapiri kai e whakamahia ana hei whakapai ake i te kakano, te pumau, me te oranga o nga momo momo hua kai. Ko te CMC he paura ma, he hongi, he kore reka i ahu mai i te cellulose, te waahanga matua o nga pakitara tipu. He polysaccharide, te tikanga he maha nga ngota ngota huka e hono tahi ana. Ka whakamahia te CMC hei maatete whakakaha, hei whakaemi, hei aukati i te hanga o te karaihe huka i roto i nga kai reka tio. Kei te whakahaerehia e te FDA i te United States, me te taumata teitei o te whakamahinga o te 0.5% i te taumaha.
