Abstract

A study on development of non destructive and low cost device has been conducted to predict cavendish banana ripening stage by using visible lights reflectance method. The system uses green (500-560 nm, peak at 533 nm), orange (580-610 nm, peak at 597 nm), and red (600-650 nm, peak at 632 nm) lights which has high corellation to spectral analysis by spectrophotometer at 0.91, 0.76 and 0.83 for red, orange and green lights respectively. A classification of ripening stages of banana has been made based on the lights reflectance of peel. The highest accuracy is obtained by the red light at 100%, 92%, 33% and 75% for predictions of stage 4, 5, 6 and 7 respectively compared to visual assessment of standard color chart.
