Efficient sterilization method for animal blood

Abstract

The invention relates to the technical field of bioengineering and techniques, in particular to an efficient sterilization method for animal blood. The efficient sterilization method comprises the following steps of (1) pouring the animal blood into a sterilization jar, adding deionized water in proportion, wherein the added water quantity is 0.5-2.5 times of blood quantity, and blending the concentration of materials to be 8-20%; (2) heating the materials blended in the step (1) to 65-85 DEG C, maintaining the temperature, starting an inserting type shearer mounted in the jar, and maintainingthe inserting type shearer working for 10-90 minutes; and (3) turning on a valve of a pipeline type high-speed shearer, adding the materials obtained in the step (2), starting the high-speed shearer,and maintaining shearing for 10-90 minutes. According to the efficient sterilization method disclosed by the invention, a sterilization manner is adopted, so that quick temperature rise can be realized; certain and killing and survival restraint can be performed on bacteria, and a high shear technique cooperates for use, so that the bacterium killing effects can be improved; and besides, proteindenatures moderately, so that the dispersibility is good, and favorable conditions are created for subsequent bacteria-free processing.

Description

technical field [0001] The invention relates to the technical field of bioengineering and technology, belongs to the deep processing of animal blood, and in particular relates to a high-efficiency sterilization method of animal blood. Background technique [0002] With the improvement of people's living standards, the demand for meat will also maintain a large volume. Slaughtering and processing to provide meat will inevitably produce a large amount of blood. Animal blood is a high-quality protein raw material that can be widely used in feed, food, Biological fermentation and other technical fields; at the same time, because blood protein is rich in protein, sugar and other nutrients and various trace elements, the water content is moderate, it is easy to be infected with bacteria, easy to be corrupted, and it is easy to be corrupted, which affects the quality of subsequent processing products. A large number of toxic side pollution, stench, etc., affect the environment. ...

[0002] With the improvement of people's living standards, the demand for meat will also maintain a large volume. Slaughtering and processing to provide meat will inevitably produce a large amount of blood. Animal blood is a high-quality protein raw material that can be widely used in feed, food, Biological fermentation and other technical fields; at the same time, because blood protein is rich in protein, sugar and other nutrients and various trace elements, the water content is moderate, it is easy to be infected with bacteria, easy to be corrupted, and it is easy to be corrupted, which affects the quality of subsequent processing products. A large amount of toxic side pollution, stench, etc., affecting the environment

[0003] At present, in the domestic blood processing industry, there are few effective sterilization methods except for low temperature to slow down corruption. At the same time, the time of low temperature storage is limited and low temperature storage requires cooling equipment, which will greatly increase the cost. However, high temperature sterilization will cause excessive denaturation of blood proteins, which is not convenient for industry. processing
