Non-Destructive Eggshell Strength Assessment Using Hertz Contact Theory-Part II: Implementation and Validation. [PDF]
Foods, 2023 Eggshell strength is a critical quality factor for consumption eggs as it affects the probability of breakage in practice. In this study, a fast and low-cost methodology for the non-destructive determination of eggshell strength is presented. The method utilized a small steel ball to impact the egg and a microphone to analyse the impact characteristics.
