IntroductionThis test kit is a rapid detection assay that detects disinfection effect in liquid milk. Raw milk contains a kind of enzyme, it can react to detection reagent to present blue, the depth of the blue is in direct proportion to pasteurization . after pasteurization, the enzyme has no effect, and can’t react to detection reagent to develop blue at the same condition.
