Process of production of a stable homogenized biomass hetero-colloid consisting of an aqueous continuous phase and a dispersed phase, wherein said dispersed phase consists of a biomass hetero-colloid consisting of a liquid-solid colloidal fraction comprising solid particle colloid matter consisting of insoluble fibre, and a liquid-liquid colloidal fraction comprising at least 15% (w/w) soluble colloid matter comprising soluble fibre forming macromolecular assemblies of soluble polymers, characterized in that (i) providing a micron-sized and micronized native or dry biomass, wherein said biomass is micron-sized unicellular organisms or aggregates thereof, or of micronized fungal, plant or animal origin; (ii) suspending said micron-sized and micronized native or dry biomass to a 0.1 to 30 % aqueous suspension of said biomass; (iii) homogenisation of said aqueous suspension of said biomass by wet milling with a bead / ball mill until a liquid-solid colloidal fraction and a liquid-liquid colloidal fraction comprising soluble colloid matter is formed, wherein said soluble colloid matter represents at least 15% (w/w) of said biomass prior to said homogenization; provided that (a) no other component is mixed with said biomass before suspension and subsequent homogenization or (b) no other component is added to the biomass suspension before homogenization. said dispersed phase consists of a biomass hetero-colloid consisting of a liquid-solid colloidal fraction comprising solid particle colloid matter consisting of insoluble fibre, and a liquid-liquid colloidal fraction comprising at least 15% (w/w) soluble colloid matter comprising soluble fibre forming macromolecular assemblies of soluble polymers, characterized in that (i) providing a micron-sized and micronized native or dry biomass, wherein said biomass is micron-sized unicellular organisms or aggregates thereof, or of micronized fungal, plant or animal origin; (ii) suspending said micron-sized and micronized native or dry biomass to a 0.1 to 30 % aqueous suspension of said biomass; (iii) homogenisation of said aqueous suspension of said biomass by wet milling with a bead / ball mill until a liquid-solid colloidal fraction and a liquid-liquid colloidal fraction comprising soluble colloid matter is formed, wherein said soluble colloid matter represents at least 15% (w/w) of said biomass prior to said homogenization; a liquid-solid colloidal fraction comprising solid particle colloid matter consisting of insoluble fibre, and a liquid-liquid colloidal fraction comprising at least 15% (w/w) soluble colloid matter comprising soluble fibre forming macromolecular assemblies of soluble polymers, (i) providing a micron-sized and micronized native or dry biomass, wherein said biomass is micron-sized unicellular organisms or aggregates thereof, or of micronized fungal, plant or animal origin; (ii) suspending said micron-sized and micronized native or dry biomass to a 0.1 to 30 % aqueous suspension of said biomass; (iii) homogenisation of said aqueous suspension of said biomass by wet milling with a bead / ball mill until a liquid-solid colloidal fraction and a liquid-liquid colloidal fraction comprising soluble colloid matter is formed, wherein said soluble colloid matter represents at least 15% (w/w) of said biomass prior to said homogenization; provided that (a) no other component is mixed with said biomass before suspension and subsequent homogenization or (b) no other component is added to the biomass suspension before homogenization.
