Procedimiento para preparar unos productos de digestión animales que presentan una palatabilidad mejorada para la utilización en un alimento para animales domésticos
Process for preparing a product of animal digestion having improved palatability, comprising: a) providing a viscera animal and adjust the pH of said animal offal b) contacting said animal viscera with at least one alkaline endopeptidase c) allowing said alkaline endopeptidase hydrolyzes these viscera animal c1) adding one or more ingredients of the product of Maillard digestion product of said step c) d) heat treating the product thus obtained digestion product to inactivate said alkaline endopeptidase e) obtaining said animal product digestion having improved palatability, wherein: (i) if said alkaline endopeptidase is used in an amount (E) from about 0.017 to 0.682% over the weight of the digestion product obtained after step d): - said hydrolysis step c) is performed during a time period (T) from about 1.5 to about 5.0 hours and - the product obtained after digestion product of step d) has a degree of hydrolysis (DH) from about 45 to about 70%, said DH defined by equation (1): DH> = 25.5072 + 0, 2104xE + 16,5265xT-2,3666xT2-15,6816xE2 + 9,1270xExT (ii) if said alkaline endopeptidase is used in an amount (E) from 0.717 to about 1.137% over the weight of the digestion product obtained after step d): - said hydrolysis step c) is performed for a period of time (T) from about 0.25 to about 4.0 hours and - the product obtained after digestion product of step d) has a degree of hydrolysis (DH) from about to about 70%, said DH defined by equation (2): DH> = 22.9718 + 43,58xE + 7,6128xT-0,6199xT2-21,2226xE2 + 2,3467xExT (iii) if said alkaline endopeptidase is used in an amount (E) between 0.682 and 0.717% by weight of the product obtained after digestion product of step d ): - said hydrolysis step c) is performed for a period of time (T) from about 1.5 to about 4.0 hours and - the product of the digestion product obtained after step d) has a degree of hydrolysis (DH) preferably from about 50 to about 70%, in which DH said is determined using a method based on o-phthaldia
