Process for the preparation of a plant spumate composition, comprising(a) soaking plant material in water for a predetermined amount of time at a temperature of from 40°C to 100°C for obtaining an aqueous mixture containing a plant extract and extracted plant material(b) generating a turbulent flow condition in the aqueous mixture containing a plant extract at a temperature of from 5°C to 50°C in the presence of a gaseous fluid for obtaining a foam layer containing a plant foam extract(c) separating the foam layer from the aqueous mixture and(d) drying the separated foam layer for obtaining a plant spumate composition.
