Thailand has exported fresh pomelo fruits to its neighbor country. However, many lack knowledge of the physical characteristics of the important pomelo variety. That is necessary for the design and classification of the grading system. Generally, in the pomelo market, the pomelo fruits are graded according to their size, shape and variety. Usually, fruits are graded based on size observation such as No.1, No.2, No.3 and No.4 while based on whether fruits are properly mature. Manual grading with labor is a common method that pomelo growers graded when they harvest the fruits. This study aimed to find the most suitable model for estimating the pomelo fruit mass of Thailand especially the Khao-Nampueng variety with its physical characteristics. There are not specific studies that have investigated the mass modeling of this fruit variety yet.
The results recommended that the mass model for overall fruits based on overall pomelo fruit width was the quadratic model: M = -1.2659X2 + 221.2X - 1824.1 with R² = 0.8856. While the mass model for fruit without peel based on overall pomelo fruit width was also a quadratic model: M = -13.216X2 + 496.38X – 3701.1 with R² = 0.7175. The predicted models can be useful for the design and classification of grading mechanisms for the Khao-Nampueng variety as the primary measurement before sending them to the market and transportation.
