SOME PHYSICAL PROPERTIES AFFECTING DATES CLASSIFICATION

Abstract

This research was inducted to investigate the differences between the physical properties for accepted and rejected dates for Mejdool and Saeidi varieties, to enhance the final products quality depending on their dimensional attributes. Dates' physical properties are crucial for minimizing losses during fruit handling. They also help to determine the quality of the fruit. The results showed that the difference appears between the physical properties of the accepted and rejected date fruits. In the Mejdool variety there was a difference between the mean for the properties of length, average width, mass, and volume. According to the study sample, it was shown that the accepted fruits of dates are more than (26 mm, 22 gm and 19 cm3) for the physical properties (average width, mass, and volume), respectively. Generally, as a result of the existence of an overlap in the range between the physical properties under study of the accepted and rejected date fruits, which reduces reliance on them in the classification processes. The classification processes for date fruits need other methods such as deep learning, image analysis, etc., to achieve a final good quality product.
