LED lighting extends color shelf life for three beef products compared with fluorescent lighting

摘要

Consumers are not able to estimate tenderness, juiciness, or flavor when selecting beefcuts at retail stores. Instead, they rely on color as one of the major criteria to select beefcuts. During refrigerated display, fresh meat color changes and consumers discriminateagainst discolored meats. Meat items with discoloration must be discounted ordiscarded, leading to up to $1 billion in revenue loss nationally for the meat industry.Lighting type and intensity have a major impact on the appearance and shelf life of freshbeef in refrigerated retail display. Light emitting diode (LED) lighting offers advantagesfor display because it is more energy-efficient and generates less heat than fluorescentlights. These advantages may be beneficial for fresh meat color stability.The objective of this study was to determine the effects of LED and fluorescent (FLS)lighting on visual and instrumental meat color and shelf-life properties of three freshbeef products displayed in two retail display cases that were set up to run at similartemperature profiles when case lighting was off prior to the initiation of the study.
