The invention relates to an enzymatic collagenn hydrolysate having a molecular mass of between 1000 and 50000 Daltons, low acidity and conductivity no greater than 500 μS/cm in a 1 % by weight solution. The invention also relates to a method for obtaining a collagenn hydrolysate with low total acidity from animal dermal tissue obtained under hygienic conditions from animal species suitable for human consumption (cattle, pigs, poultry and fish), which is particularly suitable for producing dairy products containing same. The method includes the following steps: aqueous extraction of the residual by-product; filtration, demineralisation and ultra-filtration of the filtered solution; enzymatic hydrolysis; concentration of the enzymatic collagen hydrolysate solution and drying of the enzymatic collagen hydrolysate. The invention further relates to nutritional supplements and functional foods containing the low-acidity enzymatic collagen hydrolysate. |
