HPMC Hypromellose

Hydroxypropyl Methylcellulose(HPMC), bụ ngwakọta kemịkalụ na-agbanwe agbanwe nwere usoro [C6H7O2 (OH) 3-mn (OCH3) m (OCH2CH (OH) CH3) n] x, ebe m na-anọchi anya ogo nke nnọchi methoxy yana n na-anọchi anya ogo hydroxypropoxy. nnọchi. A na-enweta ya site na cellulose, polymer eke sitere na mgbidi cell nke osisi. HPMC enweghị isi, enweghị ụtọ, na anaghị egbu egbu. Ọ nwere dị iche iche physicochemical Njirimara dị ka solubility na mmiri, thermal gelation Njirimara, na ike na-emepụta fim, na-eme ka ọtụtụ ebe na-eji gafee otutu ulo oru.

N'ime ụlọ ọrụ nri, a na-amata HPMC dị ka ihe mgbakwunye nri dị nchebe (E464) ma na-arụ ọrụ dị iche iche dị ka emulsifier, onye na-eme ka ọ dị arọ, na stabilizer. A na-eji ya na-emepụta ihe oriri dị iche iche iji meziwanye udidi, na-ejigide mmiri, na ịmepụta ihe nkiri oriri. Ngwongwo gelation thermal nke HPMC bara uru karịsịa na ngwa chọrọ gelling na okpomọkụ dị iche iche, dị ka nri anaghị eri anụ na nri anụ anaghị eri anụ ebe ọ nwere ike dochie gelatin. HPMC na-enyekwa aka na ndụ nchekwa na ịdị mma nke ngwaahịa esitere, sauces na desserts site na ịchịkwa crystallization na mmiri mmiri.

Ụlọ ọrụ ihe owuwu na-erite uru site na HPMC n'ichepụta ihe ụlọ.
