Abstract

The invention is a modified atmosphere package comprising about 0.1 to 5 vol. % carbon monoxide and that includes a time-temperature indicator that is disposed in a temperature monitoring relationship with the package and that is configured to indicate whether a perishable product disposed in the package has been exposed to a time-temperature exposure that may have caused spoilage of the product. The time-temperature indicator may be used to alert a person that a red meat product disposed in the package has potentially spoiled even though the meat product may have a fresh 'bloomed' appearance. As a result, the possibility of a consumer purchasing a spoiled product may be reduced. The invention is also directed to a method of using the time-temperature indicator to indicate the likelihood of spoilage in the packaged product. In one embodiment, the time-temperature indicator changes visual appearance based on a combination of predetermined times and temperatures.
