ABSTRACT:
The invention relates to an aqueous coating composition a film or barrier layer. The aqueous coating, in a pseudoplastic thixotropic mixture having a yield point, can be applied to surfaces in heated food preparation units. The composition can be easily applied to a variety of surfaces, and can advantageously cling to vertical or substantially inclined surfaces in order to form a barrier film or coating. The coating can result in a smooth uniform coating. The film, upon heating forms a barrier layer which can facilitate the removal of food soils which can form during food preparation activities after formation of the barrier film layer. The compositions of the invention can be used in methods for coating the interior heated surface of food preparation units by applying the aqueous material through a spray or other aerosol apparatus to form a clinging aqueous coating. Upon heating, the water from the coating can evaporate leaving an organic/inorganic film which can support baked-on food soil and promote easy removal. The compositions and methods of the invention entail the use of food safe materials approved for contact with comestible substances.
