Applied Food & Feed Extrusion Typical Program

This program is normally run in Thailand, where we have access to appropriate facilities through the Institute for Food Research & Product Development at Kasetsart University.

For currently planned public courses see our Events page. 

(See here for the alternate "Food & Feed Extrusion Technology" typical program offered in Australia and elsewhere)

Program details may be subject to change.
