Abstract
A process for the production of mechanically disassembled cellulose and the resultant product, referred to as microdenominated cellulose (MDC). The product is characterized by a settled volume of greater than 50%, as determined on the basis of a 1% by weight suspension in water after twenty-four hours, and a water retention value of over 350%. MDC is useful as an ingredient in foods, pharmaceutical and cosmetic products.
Claims7
A process for preparing microdenominated cellulose comprising repeatedly passing a liquid suspension of fibrous cellulose through a zone of high shear, said zone being defined by two confronting refining disk surfaces, with one of said surfaces rotating relative to the other, under conditions and for a length of time sufficient to render said suspension substantially stable and to impart to said suspension a Canadian Standard Freeness that shows consistent increase with repeated passage of said cellulose through said zone of high shear.
