Definitions

  • the invention relates to the use of an improved coating composition in a method for producing a non-blocking or peelable coating.
  • it relates to the coating of a food product with a non-blocking or peelable coating.
  • cheeses and sausages are coated to prevent physical damage, to maintain a desired shape, to reduce or prevent loss of moisture or to protect against undesired fungi including yeasts and bacteria.
  • Hard, semi-hard or soft cheeses and various sausages such as matured sausages like salami or chorizo can be protected in this way by a coating.
  • the protective coating consists in general of a plastic or polymer coating (for example a (co-) polymer based on vinyl acetate) that can be applied in a single layer or multiple layers.
  • the coating needs to be flexible because of volume changes of the food during ripening.
  • An outer layer of wax generally on basis of paraffin, can be applied on the polymer coating to block evaporative water loss and to block further ripening.
  • This type of classical coating has therefore at least two layers: one internal layer made of polymer and one external layer made of wax.
  • This type of coating is known to be difficult to be peeled from the cheese or sausage it is applied to.
  • this type of coating is known to be sticky (or blocking) (MBi/www.centrgagr ⁇ It means cheeses or sausages coated with this type of coating will stick to each other and/or stick to the surface they are laid upon (often a wooden shelf).
  • the invention provides a method wherein a wax-containing coating composition is used for producing a low-blocking coating.

  • the coating is non-blocking.
  • blocking is synonymous with sticking and low-blocking indicates that stickiness is reduced.
  • the low-blocking property of the coating reduces the adhesion of the coated substrate to any material to which it is contacted. For example, in the case of coated cheeses, this reduces the adhesion of cheeses to shelves and to the coating of neighbouring cheeses in case of contact.
  • the low-blocking aspect of the coating reduces adhesion to any material, which is beneficial to the processing of the coated product.
  • the low-blocking coating is non-blocking.
  • the blocking characteristic of any coating is preferably quantified by the following assay.
  • a wet tissue is applied on a coating to be tested for 30 minutes. After 30 minutes, the wet tissue is removed and the wetted coating is folded in order to contact the wet coating with itself (cohesion test).
  • a glass plate is placed on top of the folded coating and after 1 hour the plate is removed.
  • the folded coating is then tested on cohesion by pulling the folded coating layers apart.
  • the ease of pulling the coating layers apart is indicated by 1 , 2, 3 or 4. 1 means (almost) impossible to pull the layers apart: it means that less than 10% of the area that was into contact can be pulled apart (coating is very blocking/sticky).
  • the coatings used according to the invention are non- blocking, i.e. when tested in the assay above, the coatings give a value of 3 or 4.

  • the coatings used according to the invention are peelable (or strippable) when applied on a food product.

  • the coating is peelable during and after storage, without the need to pack the product in plastic foil or other packaging material.
  • a peelable coating possesses sufficient flexibility and strength so that it does not fracture during peeling.
  • the adhesive ability of the coating is sufficient to keep it completely bound to the underlying surface during the period of protection and yet remains peelable at the time of removal.
  • the peelable coating is peeled off without being torn in pieces.
  • parts of at least 5 cm 2 can be peeled off; preferably parts of at least 10 cm 2 , and more preferably at least parts of 20 cm 2 can be peeled off in one piece.
  • a useful coating when removed should not remain partially unpeeled, and thus not leaving parts of coating adhering to the coated surface.
  • mechanical peeling is meant that it can be peeled by a suitable apparatus or by hand.
  • the peelability of coatings is preferably tested by cutting part of a dried coating that is applied to a glass plate with a sharp object like a knife.
