Why Do We Do Mbrt Test

This test is performed to check the bacteria contamination in milk. It will visually indicate the presence of bacteria in a given milk sample, and it will indicate the level of milk quality.

What is the MBRT test?

• Methylene Blue Dye Reduction Test, commonly known as MBRT test is. used as a quick method to assess the microbiological quality of raw and pasteurized milk. • Methylene blue is a redox indicator, that lose its colour under the absence of oxygen and is thought to be reduced.

Why methylene blue is used in Mbrt?

These studies revealed that MBRT can be successfully employed to quantify viable cell count in a very short time (less than 4 min). Methylene Blue (MB) dye has been employed to check for the overall microbial load and quality control of milk and other liquid foods (Impert et al., 2002).
