A member of the executive team says everyone is aware of the effect of temperature on the quality of food products, medicines and biological compounds. Temperature-time indicators, briefly called TTIs, are simple and inexpensive equipment to monitor these effects.
These identifiers can be designed as small labels that provide a visual expression of the thermal history of the product being maintained, he said.
Using these indicators, he said, the consumer can determine whether the food product is placed in a hot or cold place at a fixed temperature.
The designed system is capable of exhibiting a distinct colour change when the temperature exceeds 35° Celsius.
He added that the use of these indicators would be very useful, especially for exported products of the country, which take longer to reach the consumer.
For example; Food products, medicines and biological compounds that require transportation can be safeguarded in a portable fridge for car.
The domesticisation of the technical knowledge of the production of these indicators, which was in control of a few countries, is one of the benefits of this research achievement.
In addition, in the present study, the nano-leaf structures have been used to increase the level of sensitivity.
This Iranian scientist added that the proposal to implement the project has won a $12,000 research grant from the World Academy of Sciences (TWAS).
“The production of these indicators in the country can be seen as a breakthrough in the food and pharmaceutical packaging industry,” he concluded.
