Solution(By Examveda Team)

Methylene blue reduction Test (MBRT) is conducted to know the efficiency of Pasteurized milk.
MBRT and RRT serve as standard tests to determine keeping quality of the milk sample in lesser time and are also simple to perform.
The principle of MBRT is based on the fact that the colour imparted to the milk by addition of appropriate concentration of the dye methylene blue will disappear more or less quickly.
