Using a computer-controlled texture analyzer we test an apple for crispness and ripeness. We explain how the consumer evaluates the quality of such a fruit and show a penetrometry-based test method to measure the properties which determine the crisp texture. This information can be scientifically analysed by the fruit harvester to understand the influencing factors for fresh fruit production, optimizing processes and grading for use in other products, thus minimizing costs.
