Abstract: The present invention relates to a method for coating seed, comprising the steps of: providing an aqueous coating solution which comprises a gelatine having a Bloom value of approximately 150 g or less and a viscosity of approximately 2.5 mPa·s or less, wherein the viscosity is measured on a 6.67% gelatine solution at 60° C.; and applying the coating solution to the surface of the seed and letting the coating solution dry in order to obtain a gelatine-based coating on the seed.

Abstract: The present invention relates to a method for manufacturing a paper having improved impermeability to grease and oil, comprising the following steps: (a) providing a paper with a first surface and a second surface; (b) applying an aqueous solution to the first surface, wherein the aqueous solution comprises from approximately 10 to approximately 50 weight % of collagen hydrolysate and at least approximately 0.1 weight % of a plasticizer; (c) drying the aqueous solution in order to obtain a coating comprising collagen hydrolysate and plasticizer on the first surface.

Abstract: The present invention relates to a method for treating a surface in order to improve the removability of microorganisms from the surface, comprising the steps: —applying a treatment solution onto the surface, wherein the treatment solution comprises an aqueous solution of a collagen hydrolysate; and—allowing the surface to dry. The present invention further relates to the use of collagen hydrolysate for treating a surface in order to improve the removability of microorganisms from the surface.
