Patent

CA 2183057

A method is disclosed which inactivates protease enzyme in fish, such as arrowtooth flounder, having this enzyme in a portion thereof. In the process, the fish are minced and then subsequently mixed with a starchy and/or proteinaceous material to form a mixture which is then subjected to high-temperature, short-time processing in a screw extruder containing a reaction zone. The present invention also relates to a method for proteolytic degradation of fish muscle having protease enzyme which includes distributing the enzyme uniformly throughout the fish muscle and drying the fish muscle thereafter. The present invention also relates to a method of making a food product and includes reducing hydrolyzed fish muscle to a powdered form, and then mixing the fish muscle in powder form with a starchy and/or proteinaceous material to form a mixture which is subsequently subjected to high temperature extrusion processing to form a desired food product. The present invention further relates to processes for tenderizing or causing substantial or complete proteolytic degradation of animal muscle by applying onto the animal muscle, protease enzyme obtained from fish having the enzyme present therein. Also disclosed is the resulting food products resulting from these processes.

Procédé destiné à inactiver l'enzyme protéase dans un poisson, tel que la plie à grande bouche, renfermant dans une partie de ses organes cette enzyme. Au cours du traitement, le poisson est coupé en morceaux puis mélangé à une substance amylacée et/ou protéinique pour obtenir un mélange qui est ensuite soumis à un traitement court, à haute température, dans une extrudeuse comportant une zone de réaction. La présente invention se rapporte également à un procédé destiné à la dégradation protéolytique des muscles du poisson renfermant l'enzyme protéase, procédé consistant à répartir uniformément l'enzyme dans tout le muscle du poisson, puis à sécher celui-ci. La présente invention se rapporte encore à un procédé de fabrication d'un produit alimentaire qui consiste à réduire le muscle hydrolysé du poisson pour le transformer en poudre, puis à mélanger la poudre obtenue avec une substance amylacée et/ou protéinique afin d'obtenir un mélange qui est ensuite soumis à un processus d'extrusion à haute température pour obtenir un produit alimentaire désiré. La présente invention se rapporte aussi à des procédés visant à attendrir le muscle de l'animal ou à provoquer une dégradation protéolytique substantielle ou totale de celui-ci en appliquant sur le muscle l'enzyme protéase prélevée dans le poisson. L'invention se rapporte aux produits alimentaires obtenus par ces procédés.
