This project explores the reasons why food spoilage indicators are not yet sold in grocery stores for consumer use. Food spoilage indicators, or time-temperature indicators as they are more widely known, are used to determine whether or not products are safe for consumption. There are several potential barriers to the wide market usage of packaging containing indicators including lack of consumer interest, additional cost, and manufacturing difficulties. However, the benefits that the product offers in the way of consumer safety cannot be overlooked.

Extensive research was augmented by a survey of 119 shoppers at local grocery stores in the central California Area to gauge consumer interest in the product. Additional research was conducted by way of a case study in which a professor at Cal Poly was interviewed on his knowledge of the smart packaging industry and the feasibility of wide market release of food spoilage indicators.
