The uncoated chips presented a Tootsie Roll, which exhibited a firm rounded curve (Fig.1a). The roundness of the curve suggested that the uncoated chips were more pliable than brittle and perhaps more firm than crisp. Once the product compresses, its crispness passes and it is relatively pliable before it finally breaks. The peak signal at about 0.6 s indicated that it was partly fractured at a lesser deformation time. In the case of MC-coated chips, the brittleness was reduced when MC concentration was increased, since the breaking time was progressively prolonged (Fig. 1b). The decrease of crispiness of MC-coated chips was indicated by the curve slope.
