PURPOSE:To obtain the subject suspension having thickening action, having smooth particles and excellent water retaining force and useful for food, etc., by suspending a regenerated cellulose obtained by preparing an alkaline suspen sion of a specific alkali cellulose, pulverizing the suspension and neutralizing and cleaning the resultant powder in water. CONSTITUTION:An alkaline suspension (preferably having 1-10wt.% cellulose concentration) of alkali cellulose having 20-500 average polymerization degree is prepared and pulverized through high-pressure homogenizer cellulose is regenerated using a large quantity of water, neutralized and cleaned and then the resultant regenerated cellulose is suspended in water to provide the objective suspension. Furthermore, the suspension consists of fine cellulose particles having low polymerization degree and having >=600 water retaining force and 1-30mum average particle diameter. |
