A final additional result observed in this study is the ability of untrained naïve volunteers to consistently discriminate between food products in terms of their crispness or hardness. In both experiments, the volunteers have been able to reliably distinguish between the different varieties expressing scores similar to those produced by a trained panel (Corollaro et al., 2013). This supports the notion that these textural properties are straightforward and easy to assess even for people lacking of any specific sensory training, despite maybe their higher difficulty in finding a consensual and unambiguous definition of those properties (Szczesniak, 1988).
