摘要：

In order to improve the total quality control (TQC) of the production and packaging of food, new non-destructive methods for in-line self-inspection are needed. It was investigated whether inducing acoustic streaming in the product, by transmitting an ultrasonic beam into the packages, could be used as a non-destructive method for detecting microbial growth in aseptic milk packages. It was shown that the velocity spectrum of the induced streaming, measured by the Doppler shift of reflected sound, decreased in packages with microbial growth.
