A recent article in the UK’s Guardian discusses how a Mondelez R&D lab tests chocolate Easter eggs for crackability. The article mentions the TA.XTPlus as part of Mondelez’s testing process. The texture analyzer pushes a vertical probe down into the outer shell of the eggs, measuring how much force is needed to crack through it.
