摘要：

This paper describes a new non-destructive way of testing for the presence of micro-organisms in sterilized packaged milk products by measuring their heat production. With a properly designed calorimeter and smart signal processing, the small heat production of the micro-organisms can be reliably detected. A prototype capable of handling 100 cartons of milk, implemented with the novel smart temperature sensors, has been fabricated and tested. These tests show that a relatively small heat production of micro-organisms creating a temperature rise of 5 mK can be detected simply and reliably.
