Patent

CA 2330011

An elongate, tubular or cylindrical foodstuff is provided, such as a sausage, that comprises an edible proteinaceous composition that is encapsulated in an edible hardened collagen-free skin comprising a protein (e.g. casein) and a hydrocolloid (e.g. alginate). Also disclosed is a process for making such a foodstuff, by coating the proteinaceous composition with a skin-forming material, and then hardening this material by chemical or physical means. Chemical treatment includes exposure to a cross-linking or gel-forming agent, which can result in hardening by cross-linking or the formation of a gel by the protein and/or the hydrocolloid. The proteinaceous composition and skin- forming material are continuously co-extruded and passed into a bath containing a cross-linking or gel-forming agent.

L'invention concerne un produit alimentaire allongé, tubulaire ou cylindrique, comme une saucisse. Ce produit comprend une composition protéinique comestible encapsulée dans une peau dépourvue de collagène, durcie et comestible contenant une protéine (par exemple, de la caséine) et un hydrocolloïde (par exemple, de l'alginate). L'invention traite également d'un procédé de fabrication d'un produit alimentaire de ce type. Ce procédé consiste à recouvrir la composition protéinique d'un matériau formant peau, puis à durcir ce matériau à l'aide de moyens chimiques ou physiques. Le traitement chimique consiste à exposer ce matériau à un agent de réticulation ou de gélification, ce qui peut se traduire par un durcissement par réticulation ou par gélification par la protéine et/ou l'hydrocolloïde. La composition protéinique et le matériau formant la peau sont coextrudés en continu et transmis dans un bain contenant un agent de réticulation ou de gélification.
