Abstract

[Problem] The present invention addresses the problem of providing a cellulose composite whereby the cellulose composite itself disperses stably even when ions are blended in a high concentration in a beverage, and also has excellent suspension stability.
[Solution] A cellulose composite comprising cellulose, an anionic polysaccharide not having a chemically crosslinked structure, and water-absorbent particles comprising a compound having a chemically crosslinked structure wherein the cellulose composite has a viscosity of 10 mPa·s or higher when 1 mass % of the cellulose composite is dispersed in an aqueous solution in which 0.45 g of sodium bicarbonate is dissolved in 100 mL of pure water.

First claim

The invention claimed is:

1. A cellulose composite comprising:
cellulose,
an anionic polysaccharide not having a chemically crosslinked structure, and
0.5 to 15 mass % of water-absorbent particles comprising a compound having a chemically crosslinked structure, wherein the compound having the chemically crosslinked structure is carboxymethyl cellulose calcium having a degree of substitution of 0.5 to 2.0, wherein the water-absorbent particles have a saturated water absorption of 3 mL/g or higher,
wherein the cellulose composite has a viscosity of 10 mPa·s or higher when 1 mass % of the cellulose composite is dispersed in an aqueous solution in which 0.45 g of sodium bicarbonate is dissolved in 100 mL of pure water.

2. The cellulose composite of claim 1 wherein the anionic polysaccharide not having a chemically crosslinked structure is selected from the group consisting of carboxymethyl cellulose sodium and xanthan gum.

3. The cellulose composite of claim 1 wherein the anionic polysaccharide not having a chemically crosslinked structure is carboxymethyl cellulose sodium.

4. The cellulose composite of claim 1 wherein a blend ratio of the cellulose/the anionic polysaccharide not having a chemically crosslinked structure is 50-99 parts by mass/1-50 parts by mass.

5. A method for producing the cellulose composite of claim 1 comprising:
compositing the cellulose, the anionic polysaccharide not having a chemically crosslinked structure, and the water-absorbent particles comprising the compound having a chemically crosslinked structure.

6. A food comprising the cellulose composite of claim 1 .

7. An industrial product comprising the cellulose composite of claim 1 .

8. A pharmaceutical comprising the cellulose composite of claim 1 .

9. A coffee beverage comprising the cellulose composite of claim 1 .
