French Fries - Acoustic Testing of Shoestring French Fries

We tested shoestring french fried potatoes with the TA.XTPlus Texture Analyzer and the Comparative Acoustic Envelope Detector (A/CAED) attachment. The A/CAED captures the acoustic signal generated by a product simultaneously with the product’s force resistance data. The premise of the study was to determine how well sound signatures differentiate between the degrees of crispness of french fries.
