Light exposure can degrade the nutritional and sensory qualities of food through photo-oxidation reactions.  Dairy foods are especially sensitive to light due to their content of photosensitive species such as riboflavin.  Fluid dairy milk has been studied extensively and research has shown the photo-oxidation reactions negatively impact both the emotional response to and flavor acceptability of milk.   To mitigate the negative effects of light on the consumer experience, fluid dairy milk packages can be designed with incorporation of light protection additives.  While the International Dairy Federation has proposed package design metrics for light protection, these metrics have proven insufficient to direct the design of light protective packages for fluid dairy milk.  To address these issues, a proprietary measurement technology and associated quantitative metric called Light Protection Factor (LPF) has been demonstrated and validated for the design and optimization of light protective fluid dairy milk packages.  This measurement technology has been used to survey the performance of current fluid dairy milk packaging with LPF and identify opportunities for light protection performance improvement.
