Hydroxypropyl MethylCellulose E464

Hydroxypropyl Methylcellulose (HPMC) jẹ polima ologbele-synthetic ti o wa lati inu cellulose.O jẹ lilo nigbagbogbo ni ile-iṣẹ ounjẹ bi afikun ounjẹ pẹlu nọmba E464.

A ṣe HPMC nipasẹ ṣiṣe itọju cellulose pẹlu apapo alkali ati awọn aṣoju etherification, eyiti o yọrisi iyipada diẹ ninu awọn ẹgbẹ hydroxyl lori molecule cellulose pẹlu awọn ẹgbẹ hydroxypropyl ati methyl.Iwọn aropo ṣe ipinnu awọn ohun-ini ti abajade HPMC, gẹgẹbi awọn ohun-ini solubility ati awọn ohun-ini gelation.

Ninu ounjẹ, a lo HPMC bi apọn, emulsifier, ati amuduro, laarin awọn iṣẹ miiran.O le ṣee lo lati mu ilọsiwaju ti awọn ọja ounjẹ bii awọn obe, awọn aṣọ asọ, ati awọn ọja didin.A tun lo HPMC bi ibora fun awọn tabulẹti ati awọn agunmi ni ile-iṣẹ elegbogi, ati ni iṣelọpọ itọju ti ara ẹni ati awọn ọja ohun ikunra.
