The present invention is a method for improving the visual appearance of a food product (12) and a film (22) utilized in the method. The film includes an effective amount of a nitrogen-containing compound contained within or applied to one side of the film and adapted to contact a food item held within a food packaging container (10). Upon contacting the food item within the container, the nitrogen-containing compound forms nitrous oxide gas within the container, because of the contact of the compound with and dissolution into the juices of the food product. Thus, the physical contact of the packaging film with the food product causes a preferred reddish bloom to appear on the viewing surface (100) of the food item without effecting the appearance, performance or color of the interior of the food product.

La présente invention concerne un procédé destiné à améliorer l'aspect visuel d'un produit alimentaire (12) et un film (22) utilisé dans le procédé. Le film comprend une quantité efficace d'un composé contenant de l'azote contenu dans ou appliqué sur une face du film et conçu pour venir en contact avec un article alimentaire contenu dans un contenant d'emballage alimentaire (10). Lors du contact avec l'article alimentaire dans le contenant, le composé contenant de l'azote forme du gaz d'oxyde nitreux dans le contenant, du fait du contact du composé avec et de la dissolution dans les jus du produit alimentaire. Ainsi, le contact physique du film d'emballage avec le produit alimentaire entraîne l'apparition d'une couleur de viande fraîche rougeâtre sur la surface de visualisation (100) de l'article alimentaire sans affecter l'aspect, les performances ou la couleur de l'intérieur du produit alimentaire.
