Abstract: This work mainly aimed at investigating quality of milk in cold chain. The effects of different storage condition on quality of milk were investigated by electronic time-temperature indicator (ETTI) and biochemical methods. The device would predict the remaining shelf life and alarm when abnormal condition. The remaining shelf life of milk has gotten by the nonisothermal conditions, whose difference of results between measurement and biochemical analysis was less than 0.5 days. The ETTI would appropriately indicate the remaining shelf life(RSL). It was better than the product date and significant to improve the cold chain for food.

Key words: time-temperature indicator, shelf life, milk
