The present invention relates to a plant protein product with colouring ingredients and to a production method. In the method, a protein formula is provided which comprises plant proteins from oil seeds or from legumes and oil seeds, and secondary plant compounds from the oil seeds. In this method, the secondary plant compounds from the oil seeds contain polyphenols which alter their colour on oxidation. The polyphenols fraction selected for the protein formula. is between 10 ppm and 0.2%. The protein formula is then extruded at a temperature of more than 100° C. in the presence of atmospheric oxygen. The addition of proteins and of the aforesaid secondary plant compounds from the oil seeds allows different hues to be established in the vegetable extrudate that lend the impression of meat in any of a variety of prepared forms, without any need to add further colorants to the extrudate.
Extruded plant protein product that contains plant proteins from oil seeds or from legumes and oil seeds, as well as secondary plant compounds from the oil seeds, wherein die secondary plant compounds from the oil seeds contain polyphenols which change colour upon oxidation, and the polyphenols constitute a fraction between 10 ppm and 0.2% of the plant protein product.
Method for producing a coloured plant protein product, in which a protein formula containing plant proteins from oil seeds or from legumes and oil seeds as well as secondary plant compounds from the oil seeds is provided and then extruded, wherein the secondary plant compounds from the oil seeds contain polyphenols that change colour upon oxidation, a fraction of the polyphenols between 10 ppm and 0.2% is selected in the protein formula, and the protein formula is extruded at a temperature of more than 100° C. in the presence of atmospheric oxygen.
