[Biological value of the proteins of a sausage product incorporating a combined protein preparation based on slaughterhouse blood].

The authors discuss experimental data obtained in the course of investigation of the biological value of proteins of combined meat products containing decolorized blood obtained with the use of a new physical method. Analysis according to the amino acid score revealed that the combination prepared from blood protein, milk serum and eggs would make it possible to replace beef and pork proteins to any extent. The biological experiments showed that the designed protein mixture of blood, milk serum and egg powder would replace not less than 25% of meat proteins. The replacement by 50% and more resulted in a decrease of the biological value of proteins contained by the combined product as compared to control.
