Method of producing edible film, film formulation, and edible film

A method of producing an edible film having a predetermined film shape, the method comprising:

• disposing a surface of a pressing plate along a cutting edge so as to configure a clearance between the cutting edge and the pressing plate;
• kneading edible powder formed of particles smaller than a film thickness, a predetermined component, and an edible liquid having a mass 35% or less of a mass of the powder in a vacuum clay kneader to generate a plastic solid material containing the edible liquid;
• extruding the plastic solid material through a multi-zone extrusion process involving a first zone for carrying and dividing the plastic solid material, a second zone with reduced air pressure for deaerating the plastic solid material, and a third zone for pushing the deaerated plastic solid material into a mold through a cooling jacket with a passage cross-sectional surface that decreases in size towards the mold, thereby applying pressure to the plastic solid material and imparting a predetermined cross-sectional shape to the plastic solid material;
• and
• slicing the plastic solid material having the predetermined cross-sectional shape with the cutting edge;
• passing the sliced plastic solid material through the clearance between the cutting edge and the pressing plate, so as to deform the sliced plastic solid material into the predetermined film shape having a predetermined thickness, wherein
• the predetermined cross-sectional shape is not the predetermined film shape.
