A High-throughput Color Measurement System for Evaluating Flesh Browning in Apples

The development of new high-quality apple ( Malus × domestica ) cultivars that are resistant to flesh browning is needed expand the use apples in food service and catering industry. However, conventional methods for evaluating can be both time-consuming costly, thereby rendering such unsuitable breeding programs must characterize a large number product samples. Therefore, it necessary develop new, simple, inexpensive methods. aim was method simultaneously measuring color values 42 samples using digital camera. processing time per sample reduced less than one-tenth method. measurement dispersion [ sd difference between two colors ] this system 0.08, equivalent nominal value general colorimeter. Time-series analysis six showed calculated index correlated well with degree judged by human perception. Further, data CIE L * b trends associated reddish- watercored-flesh samples, different from corresponding yellowish-flesh This work reports high-throughput analytical provides cautionary notes browning, which should measured on basis used normal-flesh browning.
