Evaluation of Apple Pulp Texture Based on Puncture Mechanics Experiment

Puncture mechanical properties of Golden Delicious and Fuji apple pulp were analyzed to provide a reference for evaluation of fruit texture.Taking Golden Delicious and Fuji apple as research object，using TA.XT plus texture analyzer，eight loading speeds of 0.5，1.0，1.5，2.0，5.0，9.0，13.0 and 17.0 mm/s were selected to carry out puncture mechanical tests on apple pulp，and changes of fruit essence were analyzed.Results showed that：for Golden Delicious varieties，Heidenreich index CD and Ktenioudaki index CD' had higher sensitivity and were suitable for evaluating pulp Brittleness；for Fuji varieties，curve linear length D，curve length ratio D/DS，Heidenreich index CD，Ktenioudaki index CD'，and Heidenreich index Cn had higher sensitivity and were suitable for evaluating pulp brittleness；loading speed and variety had no significant effect on puncture texture parameters of the pulp.
