PROCESS FOR PRODUCING MICROCRYSTALLINE CELLULOSE WITH REDUCED NITRITE SALT CONTENT

A process for producing microcrystalline cellulose with a reduced nitrite sale content. The process comprises the steps of: i) acidic hydrolysis of cellulosic material to produce crude microcrystalline cellulose (MCC); ii) washing and at least partially neutralizing the crude MCC obtained in step i)...

description	A process for producing microcrystalline cellulose with a reduced nitrite sale content. The process comprises the steps of: i) acidic hydrolysis of cellulosic material to produce crude microcrystalline cellulose (MCC); ii) washing and at least partially neutralizing the crude MCC obtained in step i) to obtain an MCC wet cake; and iii) spray-drying the MCC wet cake. After step ii) or step iii) or both of steps ii) and iii), the MCC is subjected to a heat treatment.
