IHydroxypropyl MethylCellulose E464

IHydroxypropyl Methylcellulose (HPMC) iyi-polymer etholakala ku-cellulose. Isetshenziswa kakhulu embonini yokudla njengesengezo sokudla ngenombolo E464.

I-HPMC yenziwa ngokwelapha i-cellulose ngenhlanganisela ye-alkali ne-etherification ejenti, okuholela ekushintsheni kwamanye amaqembu e-hydroxyl ku-molecule ye-cellulose nge-hydroxypropyl namaqembu e-methyl. Izinga lokushintsha linquma izici ze-HPMC ewumphumela, njengokuncibilika kwayo nezici ze-gelation.

Ekudleni, i-HPMC isetshenziswa njenge-thickener, emulsifier, kanye ne-stabilizer, phakathi kweminye imisebenzi. Ingasetshenziselwa ukuthuthukisa ukuthungwa kwemikhiqizo yokudla efana namasoso, okokugqoka, nezinto ezibhakwayo. I-HPMC iphinde isetshenziswe njengokwemboza amaphilisi namaphilisi embonini yezemithi, kanye nasekukhiqizeni ukunakekelwa komuntu siqu kanye nemikhiqizo yezimonyo.

I-HPMC ngokuvamile ibhekwa njengephephile ukuthi isetshenziswe futhi igunyazwe ukusetshenziswa ekudleni ama-ejensi amaningi alawulayo emhlabeni jikelele, okuhlanganisa i-US Food and Drug Administration (FDA) kanye ne-European Food Safety Authority (EFSA). Kodwa-ke, njengazo zonke izithasiselo zokudla, kubalulekile ukusebenzisa i-HPMC ngokuhambisana namazinga anconyiwe nemithethonqubo ukuze kuqinisekiswe ukuphepha kwayo.
