Hydroxypropyl MethylCellulose E464

Hydroxypropyl Methylcellulose (HPMC) jẹ polima ologbele-synthetic ti o wa lati 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 nipon, 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.

HPMC ni gbogbogbo ni ailewu fun lilo ati pe o ti fọwọsi fun lilo ninu ounjẹ nipasẹ ọpọlọpọ awọn ile-iṣẹ ilana ni ayika agbaye, pẹlu US Food and Drug Administration (FDA) ati Alaṣẹ Aabo Ounje Yuroopu (EFSA). Sibẹsibẹ, gẹgẹbi pẹlu gbogbo awọn afikun ounjẹ, o ṣe pataki lati lo HPMC ni ibamu pẹlu awọn ipele ti a ṣe iṣeduro ati ilana lati rii daju aabo rẹ.
