Congee na phenology: dịka ihe mgbaze organic maka hydroxyethyl cellulose bụ ihe mgbaze na-adịghị mma, yabụ enwere ike iji ihe mgbaze organic ndị a kwadebe congee. Mmiri ice ndị a na-ejikarị eme ihe dịka ethylene glycol, propylene glycol, na ihe ndị na-emepụta ihe nkiri (dịka hexanediol ma ọ bụ diethylene glycol butyl acetate), bụkwa ihe na-eme ka ihe ghara ịdị mma, yabụ a na-ejikarị ya na mmiri organic iji kwadebe porridge. Enwere ike itinye hydroxyethyl cellulose dị ka Porridge ozugbo na agba ahụ. A na-afụ Hydroxyethyl cellulose kpamkpam na porridge ahụ. Mgbe etinyere lacquer, ọ na-agbaze ozugbo ma na-eme ka ọ sie ike. Mgbe etinyere ya, a ga-akpali ya mgbe niile ruo mgbe hydroxyethyl cellulose ga-agbaze kpamkpam ma dị ka otu. N'ozuzu, porridge nwere akụkụ isii nke ihe na-agbaze organic ma ọ bụ mmiri ice na akụkụ nke ngwakọta hydroxyethyl cellulose, ihe dị ka nkeji 5-30 ka e mesịrị, hydroxyethyl cellulose ga-aghọ hydrolyzed ma na-aza. N'oge okpomọkụ mgbe oke mmiri dị oke elu, ọ dịghị mma maka itinye porridge.
