Abstract:
1. A process for producing a coated material, comprising: providing a coating agent comprising yeast cell wall fractions, as a primary constituent, wherein the yeast cell wall fractions consist of cell residue of yeast from which internal soluble cell constituents have been removed by treating yeast cells by autolysis, or with external enzymes selected from the group consisting of proteases, nuclease, β-glucanase, esterases, lipases and combinations thereof, or with a combination of autolysis and one or more of the external enzymes, and subsequently with an acidic aqueous solution followed by a separation step, wherein the yeast have not been treated with alkali; and coating the surface of a solid material with the coating agent to form a continuous, low oxygen or gas permeable coating thereon.
