Abstract
Abstract The invention relates to a method of surface dyeing of protein articles of food, such as meat, cheese, fish etc., particularly of protein casings used as outer coverings of food-stuffs. It consists in subjecting the protein products to the action of a dyeing substance comprising an aqueous solution of a wood-bark extract, advantageously of oak or birch bark. The protein product may be dyed: by immersing the product in the dyeing solution, by sprinkling the product with the solution or by contacting the product with an aerosol formed by spraying the solution of the extract. The dyeing process according to the invention may be applied both to raw casings and to casings filled with the food-mass in the form of batons.

Total Claims: 12
Claim 1
Independent Claim
48 words
A method for dyeing a protein food product comprising subjecting the product to the action of a dyeing substance consisting of a wood-bark extract in form of an aqueous solution having a concentration of from 0.5 to 5% until the desired color is imparted to the food product.
Claim 2
Independent Claim
48 words
A method for dyeing a protein food product comprising subjecting the product to the action of a dyeing substance consisting of a wood-bark extract in form of an aqueous solution having a concentration of from 0.5 to 5% until the desired color is imparted to the food product.
Claim 3
Dependent Claim
22 words
A method for dyeing according to claim 1 wherein the protein product is immersed in the aqueous solution of the woodbark extract.
Claim 4
Dependent Claim
18 words
