A method for producing a cellulose composite containing cellulose and a polysaccharide, wherein a median size of colloidal cellulose composites contained in the cellulose composite as measured by a dynamic light scattering method is 0.85 &#x3bc;m or more, the method including treating a mixture containing cellulose, a polysaccharide and an aqueous medium together in a wet process, wherein a solid content is controlled to be 35 mass % or more, and temperature is set at 80&#xb0; C. or less.

Highly functional cellulose composite

The present invention relates to a cellulose composite that makes separation and aggregation less likely to occur, and, more specifically, relates to a cellulose composite comprising cellulose and one or more types of water-soluble carboxymethyl cellulose wherein tan &#x3b4; of an aqueous dispersion obtained by dispersing 1 mass % of the cellulose composite in ion-exchanged water is 0.6 or lower.

Cellulose composite

A cellulose composite which contains a cellulose and a polysaccharide and which is characterized in that the median diameter of colloidal cellulose composites contained in the cellulose composite is 0.85 &#x3bc;m or more as measured by a dynamic light scattering method.

Cellulose composites of cellulose and a hydrophilic gum, the cellulose composite giving a 1-mass % aqueous dispersion thereof, which has a storage modulus (G') of 0.06 Pa or more when the pH thereof is 4.

Disclosed is a cellulose composite which comprises cellulose and a hydrophilic gum, the cellulose composite giving a 1-mass % aqueous dispersion thereof which has a storage modulus (G') of 0.06 Pa or more when the pH thereof is 4.
