The invention relates to a method of manufacturing a foil or coating based on water-insoluble proteins comprising the steps of: a) suspending in water at least one water-insoluble protein; b) spreading the obtained suspension on a support; and c) removing the water from the suspension to obtain a continuous film. In preference the water-insoluble protein is chosen from the group consisting of vegetable proteins, naturally water-insoluble or made water-insoluble, from cereals such as for instance wheat, in particular wheat gluten, maize, barley, rye, millet etc., proteins from tuberous plants such as for instance potatoes, proteins from pulses such as soya, peas, beans, broad beans etc., or combinations thereof or animal proteins which are naturally water-insoluble or made water-insoluble such as collagen, gelatin, lactoproteins, egg proteins and blood proteins or combinations thereof. The suspension contains at least one additive which can be chosen from the group consisting of thickeners, plasticizers, acids, proteins, hydrophobic substances or combinations thereof. |
