Temperature‐Controlled Conversion of Boc‐Protected Methylene Blue: Advancing Solid‐State Time‐Temperature Indicators

“…Electronic log devices (eTLog) are prevalent in monitoring temperature during the transportation of high value sensitive products [3] such as pharmaceuticals, [4] vaccines, [5] like mRNA‐based Covid‐19 vaccines, [6] and refrigerated and frozen consumer food packages. But the transport data of eTLog devices is not commonly available to end‐consumers, which is important if any intermittent increase in temperature (so called temperature abuse) had occurred [1b] . Since eTLog devices are too expensive (≈100 USD/piece) to use on food packages like those for chilled seafood and meat products, alternative time‐temperature indicators are developed [7] .…”

[1b] Since eTLog devices are too expensive (≈100 USD/piece) to use on food packages like those for chilled seafood and meat products, alternative time‐temperature indicators are developed. [7] These TTIs exhibit a change in color indicating temperature abuse, assuring consumer about proper cold‐chain management and any potential loss of quality.…”
