ultrasonic testing of food products

I am seeking information of a rather specific nature-can anyone direct me to research on UT with food products? I am also trying to get a few ideas from experts in the field regarding the technological advancements required in the field of NDT that must occur in order to be able to safely test food products (especially for the presence of bacteria). Thanks so much,

E. Verhoeven, M.S.

Dear Elizabeth,

There are several research groups in the UK that use ultrasonic testing for evaluation of food products. A lot
of this work is for quality assurance and process control but they may have an interest in your specific area of
food safety.

Here are links to two food research groups in the UK that employ UT.

Thanks so much,

A couple of my colleagues at Panametrics have written on the subject. Sohale Samari wrote a summary paper on ultrasonic inspection techniques for food products back in 1994, entitled "Ultrasonic Inspection Methods for Food Products". I have copies available, so if you or anyone else who's interested in the subject would like one, please send me a postal address or fax number and I'll send it off.

You can also find a chapter on food inspection and analysis in the book "Ultrasonic Measurements for Process Control" by Lawrence C. Lynnworth (Academic Press, 1989). Larry's book includes an extensive bibliography.

We've done occasional food experimentation in my lab in support of customers, on products ranging from egg shells to meat. If you can indicate the specific test you're trying to perform, I may be able to offer additional advice.

We have used our system for food and polymer industries. If you can send us details, perhaps we can help you as we have measured within ppm level for food product manufacturer. However, we have not measure the presence of bacteria, but it is worth ivestigating the approach.

Many years ago I used acoustic emission to determine whether or not canned food products were spoiled by 'listening' to the cans for the chemical reactions / outgassing that was taking place inside them due to contamination. To accelerate the reaction we also tried raisingthe temperature of the can which appeared to work very well.
