A method for decolorizing and deodorizing animal plasma protein powder

Abstract

A method for decolorizing and deodorizing animal plasma protein powder, which is completed according to the following steps: adding an anticoagulant to animal blood, centrifuging to separate the plasma and blood cells, collecting the plasma, adding an acidic organic solvent to it, stirring and extracting for a period of time, and then vacuum filtration , until the decolorization is complete, then use alkaline organic solvent to filter to neutrality, and finally spray dry it into powder to obtain decolorized and deodorized animal plasma protein powder. The present invention adopts an acidic organic solvent extraction and decolorization method to remove the color of the plasma protein powder itself and the hemoglobin mixed therein, and at the same time remove its bloody smell. When the heme is separated from the globin, the globin is precipitated to achieve The purpose of decolorization and deodorization. Moreover, the organic solvent waste liquid generated in the whole process can be recovered by distillation. The plasma protein powder produced by the invention can be widely used in food industries such as cakes, ham sausages, bread, and biscuits.

Description

Technical field: [0001] The invention relates to the field of biotechnology, and relates to a method for decolorizing and deodorizing animal plasma protein powder. Background technique: [0002] Plasma protein powder is a new type of protein resource that has been reported and studied more in the feed industry in recent years. The current processing technology of plasma protein powder is to anticoagulate and separate the fresh blood of animals collected in the slaughterhouse, and separate the plasma from the blood. , then concentrate and store at low temperature, and then use a special spray-drying process to make a light yellow to tan plasma protein powder product. [0003] Generally, the protein content of plasma protein powder is more than 75%, the fat content is more than 2%, the ash content is less than 9%, the content of essential amino acids such as lysine, tryptophan and threonine is relatively high, and the amino acid composition is ideal. The ratio is more balance...

AI Technical Summary

Problems solved by technology

[0004] However, the processing technology of plasma protein powder currently on the market is simple and extensive, and it is only suitable as raw material for piglet feed

This is because the phenomenon of red blood cell rupture and hemolysis will inevitably occur during the transportation and storage of animal blood, and due to the limitation of the precision of the separation equipment in the process of animal blood separation, the color of plasma protein powder is darkened and has a certain smell of blood, which limits the ability of animals. The scope of application of plasma protein powder in the food industry
