Abstract
The present invention relates to a method for producing low-ash poultry plasma protein powder by utilizing poultry blood. Specifically, the method of the present invention comprises the steps of: mixing the poultry blood with an anticoagulant to obtain anticoagulated whole blood; centrifugally separating the anticoagulated whole blood to obtain plasma liquid; de-calcifying the plasma liquid via a precipitation reaction, ultra-filtrating the plasma liquid via a ultra-filtration membrane, emulsifying, and nano-filtrating to obtain the concentrated plasma liquid; and drying the concentrated plasma liquid to obtain the poultry plasma protein powder. The method of the present invention effectively overcomes the defect of difficult poultry blood deep processing, achieves the recycling of poultry blood resource, avoids wasting resources, and reduces environmental pollution; and the produced plasma protein powder has the advantages of high protein content, good palatability, balanced amino acid and the like.
