Puas yog cellulose gum yog qab zib?

Cellulose gum, tseem hu ua Sodium carboxymethyl cellulose (CMC), tsis yog qab zib. Hloov chaw, nws yog cov dej-soluble polymer uas tau los ntawm cellulose, uas yog cov organic polymer ntau tshaj plaws hauv ntiaj teb. Cellulose yog ib qho nyuaj carbohydrate uas pom nyob rau hauv cell phab ntsa ntawm cov nroj tsuag, thiab yog ua los ntawm cov rov qab units ntawm qabzib.

Thaum cellulose yog carbohydrate, nws tsis suav hais tias yog qab zib. Qab Zib, tseem hu ua carbohydrates los yog saccharides, yog ib chav kawm ntawm molecules uas yog tsim los ntawm carbon, hydrogen, thiab oxygen atoms nyob rau hauv ib qho piv txwv. Qab Zib feem ntau pom muaj nyob rau hauv txiv hmab txiv ntoo, zaub, thiab lwm yam zaub mov raws li cog, thiab yog ib qho tseem ceeb ntawm lub zog rau tib neeg lub cev.

Cellulose, ntawm qhov tod tes, yog ib hom carbohydrate uas yog indigestible los ntawm tib neeg. Txawm hais tias nws yog ib qho tseem ceeb ntawm tib neeg kev noj haus raws li cov khoom noj muaj fiber ntau, nws tsis tuaj yeem tawg los ntawm cov enzymes hauv tib neeg txoj hnyuv. Hloov chaw, nws dhau los ntawm txoj hnyuv loj tsis hloov pauv, muab ntau thiab pab zom zaub mov ntawm lwm yam khoom noj.

Cellulose gum yog muab los ntawm cellulose los ntawm cov txheej txheem ntawm kev hloov tshuaj. Cov cellulose tau kho nrog alkali los tsim cov ntsev ntsev, uas tom qab ntawd rov ua dua nrog chloroacetic acid los tsim cov carboxymethyl cellulose. Cov khoom tsim tau yog cov dej-soluble polymer uas tuaj yeem siv los ua cov thickener, stabilizer, thiab emulsifier hauv ntau yam khoom noj, tshuaj pleev ib ce, thiab tshuaj.

Thaum cov pos hniav cellulose tsis yog qab zib, nws feem ntau yog siv los hloov cov suab thaj hauv qee yam khoom noj. Piv txwv li, hauv cov dej haus uas tsis muaj calorie lossis tsis muaj qab zib, cov pos hniav cellulose tuaj yeem pab muab kev ntxhib los mos thiab qhov ncauj tsis ntxiv cov suab thaj lossis calorie ntau ntau. Ua li no, cov pos hniav cellulose tuaj yeem pab txo qis cov piam thaj tag nrho ntawm qee yam khoom noj, ua rau lawv tsim nyog rau cov tib neeg uas saib xyuas lawv cov piam thaj kom tsawg lossis tswj cov mob xws li ntshav qab zib.
