Uthini umahluko phakathi kwe-HEC kunye ne-MHEC?

I-HEC kunye ne-MHEC zimbini iintlobo zezixhobo ze-cellulose-based polymers ezisetyenziswa kwiintlobo ezahlukeneyo zezicelo, kubandakanywa njenge-thickeners, i-stabilizers, kunye ne-emulsifiers kwiimveliso zokutya, kunye neemveliso zamachiza kunye nezithambiso. Umahluko omkhulu phakathi kwezi zibini kukuba i-HEC i-hydroxyethyl cellulose, ngelixa i-MHEC i-methyl hydroxyethyl cellulose.

I-HEC i-polymer e-soluble yamanzi ephuma kwi-cellulose, i-polysaccharide yendalo efumaneka kwizityalo. Iqulunqwe ngetsheyini edibeneyo yeemolekyuli zeglucose kunye neqela le-hydroxyethyl elincanyathiselwe ekupheleni kwemolekyuli nganye. I-HEC cellulose isetyenziswa njenge-thickener, stabilizer, kunye ne-emulsifier kwiimveliso zokutya, kunye nakwimveliso yamayeza kunye ne-cosmetic. Ikwasetyenziswa ekwenzeni iphepha kunye nokushicilela, kunye nokwenza izinto zokuncamathelisa kunye nokugquma.

I-MHEC yindlela elungisiweyo ye-HEC cellulose apho iqela le-hydroxyethyl litshintshwa kunye neqela le-methyl. Oku kuguqulwa kwandisa i-hydrophobicity ye-polymer, iyenza ukuba ixhathise ngakumbi kwizinto ezinyibilikayo emanzini. I-MHEC isetyenziswe kwiintlobo ezahlukeneyo zezicelo, kubandakanywa njenge-thickener, i-stabilizer, kunye ne-emulsifier kwiimveliso zokutya, kunye neemveliso zamachiza kunye ne-cosmetic. Ikwasetyenziswa ekwenzeni iphepha kunye nokushicilela, kunye nokwenza izinto zokuncamathelisa kunye nokugquma.

Isishwankathelo, umahluko omkhulu phakathi kwe-HEC cellulose kunye ne-MHEC kukuba i-HEC i-cellulose ye-hydroxyethyl, ngelixa i-MHEC i-methyl hydroxyethyl cellulose. Zombini imathiriyeli zisetyenziswa kwizicelo ezahlukeneyo, kubandakanywa njengezinto ezityebileyo, izizinzi, kunye nezithambiso kwimveliso yokutya, nakwimveliso yamayeza neyokuzithambisa.
