The visual colour of the CH-Sys irreversible changed from light violet to light yellow after a specific temperature range exposition (40–70 C). This indicator system has potential applications in different areas that the exposition of temperature in a range of 40–70 C could promote total or partial degradation, such as food, pharmaceuticals, biological, agricultural, vaccines and other products. The convenience of colourimetric visually detection and simple manufacturing are advantages of this temperature indicator prototype. Also, an efficient and alternative temperature indicator packaging material was obtained based on biodegradable and safe grade materials (chitosan, card paper and ATH). Luminosity accelerated the ATH molecule degradation. Indicators associated with intelligent packaging shows large potential for safe and quality food products.
