RESAZURIN TEST

Introduction 

Resazurin is a kind of test that is done to check the quality of the milk and its consistency. The milk that is contained in a bulk has been tested through this test because it is not possible for the test if the quantity of the milk is less. Through this test, the milk has been given a bluish color to its character. Initially, the test is based on the bacteria that are present in the milk. 

Genetic engineering is a process that uses the recombinant technology of DNA to adjust an organism of the genetic makeup. Often it is used to add any other species to the organism genome. 

What is the Resazurin test?

Resazurin is a type of test that defines the quality and consistency of the milk. It also determines the bacteria that are present in the milk. This test is designed to assess the quality of raw milk. It is a rapid test of three hours that suggests the milk whether is all good or bad for us. The resazurin test gives the bluish characteristic color to the milk that is all based on the quality of the milk. The milk quality is considered by only noting the color change degree of the milk. 

Through an earlier report, it is found that this test is particularly a chemical indicator that can determine the sanitary quality of the bulked milk. This test is also used to conclude more prominent information on milk quality. This test takes place in an isolated laboratory and there is no point of compromise at the time of the test in the laboratory at any cost. The blue color of the milk suggests the perfect character of the milk after testing the milk. 

How does the test form?

This crucial test made it happen to the isolated laboratories. Certain processes indicate the perfect ways for making the test. Firstly, the milk needs to be in a high quantity contained in a bulk and after that solution of dye, resazurin has been measured into a sterile tube. Secondly, the samples of the milk are procured directly from the dipper can. A minimum temperature needs to be maintained in the laboratory. If the temperature is not maintained carefully, either the milk will freeze or the milk can be coagulated. Then the sample milk was incubated for at least 1 hour at the normal temperature of 98 degrees Fahrenheit. After all these processes, the sample milk was examined and read very carefully and quickly as possible. Around 300 milk samples have been collected for the resazurin test and that runs over five consecutive weeks. Lastly, the standard plate points to the milk sample. If the color of the milk does not change then the milk is considered as the pure one to be used in the Indian market specifically in Kerala. 

Resazurin test color chart 

The test is a kind of process that shows a vivid and clear concept of the pure milk that can be used for drinking. The bacteriological quality of the raw milk is the main thing to be determined through the help of this resazurin test. The dye resazurin has been made familiar for the replacement of the methylene that is blue. This resazurin test of milk has some definite color charts that will help to indicate the quality of the milk. Some colors form while the sample milk is running through the resazurin test. Those colors are such as excellent blue. The light blue, good purple, fairy purple, bad pink, white, and many colors are more prominent. The sample milk process is in an isolation laboratory and thus it needs to be highly maintained. After the comparison with other tests regarding the resazurin test, the sample milk has been evaluated for its usefulness. This resazurin test for the actual purpose has been compared to some other tests that are mastitis tests. However, the resazurin color chart exemplifies the sample milk at the end. 

Conclusion

The resazurin test indicates the quality of the milk that is going to be used among the people. The scholars will easily understand the actual need for this chemical test. The blue color and other colors such as pink, purple, and many others are the ones that indicate the consistency of the milk. Thus, the color chart of the resazurin test is presented. In addition, the proper procedures, the temperature under which the milk sample can be stored and tested are some of the crucial things that need to be known to future scholars.
