This work describes the design of a film coating based on polysaccharides of bacterial and plant origin with several methods of application (by spraying, brushing and wrapping) on food. We used the bacterial polysaccharide xanthan as a thickener, the plant polysaccharide carboxymethyl cellulose (CMC) as a structurant, and the biological additive lecithin as a plasticizer. Depending on the film coating application method, concentrations of the studied polymers were selected with the same component composition. A technology for preparing the film coating was developed. The influence of heating (40, 50, 60, and 70 ° C) on the solubility of polysaccharide solutions with several component ratios was studied; the temperature of 50 ° C was chosen as resulted in a strong, stable, but not too viscous gel. The effect of concentration on the appearance and thickness of the film coatings was studied.
