1. A cellulose-containing complex comprising 60 to 80 wt % of cellulose having 30 to 375 of an average polymerization degree, 2 to 12 wt % of locust bean gum, 0.5 to 8 wt % of xanthan gum and 0.5 to 37.5 wt % of a hydrophilic material(s) obtained by subjecting a mixture of 60 to 80 wt % of the cellulose, 2 to 12 wt % of the locust bean gum, 0.5 to 8 wt % of the xanthan gum and 0.5 to 37.5 wt % of the hydrophilic material(s) to wet co-grinding treatment in the presence of 20 to 60 wt % of water, and then drying to form a powder,
wherein said complex has a property (A) wherein when said complex has been dispersed in water at 8000 rpm for 5 minutes with a homomixer at 85° C., said complex forms particles having an average particle size of 60 μm or less, the proportion of particles with a particle size of 100 μm or more among the formed particles is 30 vol % or less based on the total volume of the formed particles, and
wherein said complex has a property (B) wherein when said complex has been dispersed in a 1% aqueous suspension at 25° C. and 15000 rpm for 2 minutes in a homogenizer, the dispersed complex has a colloid fraction of 30% or less.
