Light Oxidation

Did you know that a study from the Milk Quality Improvement Program found that consumers prefer 14-day-old fluid milk that has been protected from light over freshly pasteurized milk that has been exposed to strong lights? This light exposure results in light oxidized defects, sometimes called “light struck” defect. Check out our infographic on light oxidation in fluid milk to learn more about this defect and how to prevent it.

Machine learning tools identify key practices impacting fluid milk contamination

Nicole Martin, PhD

A recent Milk Quality Improvement Program study published in the Journal of Food Protection leveraged advanced statistical tools and machine learning to identify quality management practices in processing facilities that are associated with post-pasteurization contamination in fluid milk. Post-pasteurization contamination (PPC) is a barrier to high quality fluid milk, often causing pre-mature spoilage of product which can impact consumer acceptance and willingness to purchase.

Many fluid milk processors struggle to control PPC, especially when multiple factors at an individual facility may be directly and indirectly causing the contamination. Our study identified that the most important drivers of PPC are; i) cleaning and sanitation practices; ii) activities related to good manufacturing practices; iii) container type (a proxy for different filling equipment); iv) in-house finished product testing, and; v) designation of a quality department. Fluid milk processors should use these results to prioritize implementation of intervention strategies to reduce PPC. Read the fully study (https://doi.org/10.4315/JFP-20-431) or contact Sarah Murphy or Nicole Martin with questions.
