| 摘要 |
Microdenominated cellulose (MDC) is prepared by repeatedly passing a liquid suspension of fibrous cellulose through a zone of high shear, said zone being defined by two confronting 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. The product is characterised 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. <IMAGE> |
