Time–temperature indicators (TTIs) offer a promising, non-destructive approach for monitoring the combined effect of time and temperature on food products by recording their temperature history throughout storage and distribution. By providing a real-time signal of temperature-induced quality loss, TTIs help assess product quality throughout storage and distribution.
