Abstract—Pomelo maturity was evaluated based on peel optical properties and characteristics. Four stages of maturity were harvested at 5.5, 6.0, 6.5 and 7.0 months after anthesis. All optical parameters and peel related variables were used to develop a multivariate classifying model with the discriminant analysis. The accuracy of classifying all samples into immature, early-mature, late-mature and mature groups was 83.3%. The most distinguishing difference between a group of the immature and early-mature pomelos from a group of the late-mature and mature pomelos was a variation of green colour between the oil gland and the peel surface.
