Case Study: a leading dairy manufacturer standardizes milk color measurement with HunterLab ColorFlex® L2

a leading dairy manufacturer standardizes milk color measurement with HunterLab and achieves 0.15 inter-instrument delta

A leading dairy manufacturer was facing challenges with inconsistent milk color evaluation across its production shifts and laboratory locations. The company relied on subjective visual inspections and legacy instrumentation, which led to variability and difficulty maintaining strict color tolerances for regulatory compliance and brand consistency. They sought a scientific, objective solution and partnered with HunterLab to implement the ColorFlex® L2 spectrophotometer.

HunterLab implemented its ColorFlex® L2 spectrophotometers, which provided advanced optical geometry for accuracy, strong inter-instrument agreement with an average delta of 0.15, and a sealed, spill-proof design for the dairy environment. The solution standardized milk color measurement, resulting in objective data-driven decisions, reduced batch rework and waste, improved inter-lab confidence, and enhanced consumer perception due to consistent product color. HunterLab's solution provided the manufacturer with long-term instrument reliability and transformed their quality control into a data-driven system.
