Example Embodiment

[0012] The present invention will be further described in detail below in conjunction with specific embodiments:

[0013] In the method for extracting high-purity short peptide protein powder from animal blood, the main preparation process steps are: preparing food-grade protein powder from animal blood. The main content includes the establishment of related quality and safety control systems, the realization of vacuum blood sampling and simultaneous quarantine, the improvement of separation conditions and the improvement of the separation effect of blood by adding a certain amount of ideal anticoagulant and the use of low-temperature continuous separation technology. Continuous separation of blood cells; the main preparation process steps are: separating animal blood into plasma and blood cells by a centrifuge. After the blood cells are subjected to microwave-enzyme double-effect breaking treatment, the blood cells are separately added with water or mixed with the plasma and then...

Abstract

The invention discloses a method for extracting high-purity short peptide protein powder from animal blood and belongs to the technical field of food processing. The method is used for solving the problems of great loss of active ingredients and low content of short peptides and free amino acids of prepared hemocytes or/and plasma short peptide protein powder. The method for extracting the high-purity short peptide protein powder from the animal blood comprises the following steps: (a) separating the animal blood into plasma and red blood cells through a centrifuge; (b) performing thermal denaturation treatment on the red blood cells; (c) performing ultrafiltration and concentration; (d) performing sedimentation treatment; (e) performing chromatography; and (f) freeze-drying. The method for extracting the high-purity short peptide protein powder from the animal blood can be widely applied in extraction of the high-purity short peptide protein powder from the animal blood.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a method for extracting high-purity short peptide protein powder from animal blood. Background technique [0002] Generally, the extraction method of protein powder includes the steps of: separating animal whole blood into plasma and blood cells by centrifugation; and then using spray drying method to dry the separated animal plasma into plasma protein powder, wherein when spraying the animal plasma, the hot air enters the temperature It is 160-220°C, and the outlet air temperature is 40-80°C. In addition, the separated blood cell part can also be spray-dried or granulated to obtain animal blood cell protein powder. Its disadvantage is that the prepared blood cell or / and plasma short peptide protein powder has a large loss of active ingredients, and the content of short peptides and free amino acids is low. Contents of the invention [0003] The present invention over...
