Abstract
The present invention relates to cellulose casings, whether reinforced or not, capable of transferring color to the product stuffed therein. These casings contain a food dye transferable to the stuffed product during processing. The present invention also relates to the method of obtaining the casing and the product stuffed in said casing.
Claims20
A casing for stuffed products comprising two layers of cellulose including:
- an inner layer comprising regenerated cellulose and annatto, wherein the annatto comprises norbixin;
- and
- an outer layer comprising regenerated cellulose concentric to the inner layer, wherein the casing comprises norbixin and between 50% and 100% by weight of the annatto is distributed in an inner half of an area comprised by the inner and the outer layer of the casing.
A method for obtaining a casing for stuffed products comprising two layers of cellulose including:
- an inner layer comprising regenerated cellulose and annatto, wherein the annatto comprises norbixin;
- and
- an outer layer comprising regenerated cellulose concentric to the inner layer, wherein the casing comprises norbixin and between 50% and 100% by weight of the annatto is distributed in an inner half of an area comprised by the inner and the outer layer of the casing, the method comprising:
- adding an oily bixin solution to the viscose;
- extruding in an extruder with a head comprising at least two concentric circuits, an inner circuit and an outer circuit, a product of adding the oily bixin solution to the viscose in the inner circuit and viscose in the outer circuit;
- and
- hydrolyzing bixin to norbixin after after adding the oily bixin solution to the viscose.
A casing for a stuffed product obtained by:
- adding an oily bixin solution to viscose;
- extruding in an extruder with a head comprising at least two concentric circuits, an inner circuit and an outer circuit, a product of adding the oily bixin solution to the viscose in the inner circuit and viscose in the outer circuit;
- and
- hydrolyzing bixin to norbixin after the extruding operation.
