Abstract
The present invention basically consists of printing proofing marks on a film, placing it in contact with a food product, followed by an intense drying at low relative moisture and a smoking step which also occurs at low relative moisture for obtaining areas having a more smoked color in the food product under the proofing marks than in the areas not protected by said proofing marks.
Claims20
A process for obtaining smoked food products with darker marks on surfaces of the food products, comprising the steps:
- (a) printing proofing marks that are substantially impermeable to water and smoke into the surface of a film that is substantially permeable to water and smoke to create a printed part of the film;
- (b) coating the surface of a food product with at least the printed part of the film;
- (c) drying the food product and the printed part of the film coating the surface of the food product, to a relative moisture of less than 25%;
- (d) smoking the food product and the printed part of the film coating the surface of the food product so as to obtain areas on the surface of the food product in correspondence with the position of the proofing marks with a darker smoked color mark appearing beneath the proofing marks than on a remainder of the surface of the food product.

- and
- (e) during the smoking step and before coloring compounds of the smoke react with the surface of the food product, moistening and washing the surface of the food product for entraining the coloring compounds which have been diffused on the moist surface of the food product, the coloring compounds received by diffusion and remaining under the proofing marks then reacting with the food product giving rise to areas with the darker smoked color marks.
