The invention relates to the method of making a non-bleeding and edible color film coating for seeds and the like comprising a pigment and an edible film-former polymer which acts as an effective moisture barrier preventing color bleeding. The method includes preparing a pigment suspension in alcohol, with or without the use of a protective colloid, mixing the pigment suspension with a solution of an edible film-former polymer in mixtures of water and alcohol, prepared with or without the use of a plasticizer, and applying the film coating to a seed. Additionally, the invention relates to the method of making a non-bleeding and edible color film coating for seeds and the like using a film-former pigment, without using an edible film-former polymer. |
