Apparatus for processing organic material is disclosed which breaks down the inedible components of fruit and vegetables (core, skin, pips, pithy material) into an edible substance with a cream-like consistency. The apparatus includes a piston in a barrel for pressurizing the material and forcing it through a passage having a number of end-to-end sections which are at right angles to one another. There is an impact surface at the end of each section on which the flowing material impacts. The sections can be between a sleeve having sections of different diameters and a bobbin the outer surface of which is stepped to match the inner surface of the sleeve.
