Hydroxypropyl MethylCellulose E464

Hydroxypropyl Methylcellulose (HPMC) waa polymer semi-synthetic ah oo laga soo qaatay cellulose. Waxaa caadi ahaan loo isticmaalaa warshadaha cuntada sidii cunto lagu daro oo leh lambarka E464.

HPMC waxa lagu sameeyaa daawaynta cellulose oo leh isku darka alkali iyo etherification wakiilada, taas oo keenta in lagu beddelo qaar ka mid ah kooxaha hydroxyl on molikula cellulose la hydroxypropyl iyo methyl kooxaha. Heerarka beddelka ayaa go'aaminaya sifooyinka HPMC ee ka soo baxay, sida milmaheeda iyo sifooyinka gelation.

Cuntada, HPMC waxa loo isticmaalaa dhumuc weyn, emulsifier, iyo xasiliye, iyo hawlo kale. Waxa loo isticmaali karaa in lagu wanaajiyo qaabka cuntada sida suugada, dhaymada, iyo alaabta la dubay. HPMC waxa kale oo loo isticmaalaa sida dahaarka kiniiniyada iyo kaabsal ee warshadaha dawooyinka, iyo sidoo kale in wax soo saarka ee daryeelka shakhsi ahaaneed iyo alaabta la isku qurxiyo.

HPMC waxaa guud ahaan loo arkaa inay badbaado u tahay isticmaalka waxaana u oggolaaday in cuntada lagu isticmaalo wakaalado badan oo sharci oo adduunka ah, oo ay ku jiraan Maamulka Cuntada iyo Dawooyinka ee Maraykanka (FDA) iyo Maamulka Badbaadada Cunnada Yurub (EFSA). Si kastaba ha ahaatee, sida dhammaan cuntooyinka lagu daro, waxaa muhiim ah in la isticmaalo HPMC si waafaqsan heerarka iyo xeerarka lagu taliyey si loo xaqiijiyo ammaankeeda.
