Abstract
The invention relates to cellulose casings for food products and more particularly to pigmented tubular cellulose casings and to a method for the manufacture thereof. In the method for the manufacture of pigmented cellulose casings perylene tetracarboxylic acid pigment, in admixture with an additional pigment/pigments, is incorporated in the casing in order to produce a casing, which when stuffed with food products, produces the appearance of the product being naturally smoked, mahogany colored or any shade of red color. The additional pigment is selected from the group comprising (-phthalocyanine, diazo and monoazo pigments. The pigmented cellulose casing comprises 0.4-4 wt %, preferably 1-2 wt % of perylene tetracarboxylic acid.
