Color analysis is commonly used for quality control in meat production, but many times food spoilage occurs after a product reaches the supermarket shelf or the final consumer destination. At this point, freshness can be difficult to monitor and with the possibilities for improper storage and handling, the potential for contamination increases. Food borne illnesses are sweeping the headlines and making consumers leery of packaged meat products, so finding ways to differentiate between fresh meats and their inedible counterparts is an ever growing concern. New sensor film technology utilizes color analysis technology to help retailers and consumers identify potentially dangerous food products and avoid any adverse repercussions from spoiled meats.

If Only Looks Could Tell

The human eye alone cannot accurately quantify changes in meat product freshness. That hamburger you bought on Tuesday may still look edible by Thursday, but we can’t rely on our own senses or an expiration date to judge meat quality and safety. Many factors can contribute to food spoilage and without advanced sensory tools and testing to detect contamination, misguided judgements can easily lead to potentially serious problems. With the added concern over rotten meat scandals within the last decade1, the increased need for protective packaging is essential for setting consumers’ minds at ease.

The meat industry has relied on color analysis for many years to monitor the quality and safety of meats. Spectrophotometry utilizes color technology to monitor these products and is an approved method of analysis according to USDA (United States Department of Agriculture)2 regulatory standards. Sensor film technology uses these same principles to measure color changes by integrating plastic film material with an indicator dye that responds in a color change3. This technology reacts to the amines released by the meat products and provides a visual change in the plastic material that is then visible to the human eye. Color technology ensures that both the changes in meat quality and the plastic materials coincide with the safety of the food product.

Affordable, Yet Effective

Spectrophotometry has provided a valuable and affordable tool for the analysis of plastic materials and food products alike, so it is no wonder that color technology is now spanning the bridge between both products. Color changing polymer technology has already laid a solid foundation in many other various industries, so utilizing these scientific principles in food manufacturing and packaging is the next logical step.

Sensor film development is working towards improving the safety of the products consumers depend on for freshness and quality. This innovative plastic material offers a comparable and effective method of analysis that is more affordable than expensive electronic sensors. With continued development, this product can also be utilized within the food packaging industry to provide a visual tool with the ability to test the freshness of foods directly through various stages of color change.

The Role of Spectrophotometry in Product Innovation

As scientists continue to look for new ways to improve the quality and safety of the foods and products we use daily, spectrophotometric technology provides the reliable method of color analysis needed for the development of these new products. Color technology innovations stem from the basic scientific principles of color measurement and spectrophotometry continues to expand with new evaluative methods in the food, plastic, and chemical industries.
