Characterization of physical and engineering attributes of Thanjavur Ponni rice and the study of their interrelationships for quality evaluation of the rice grains

Abstract

The physical characteristics of rice grains play a crucial role in determining quality, forecasting storage behavior, and enhancing the design of processing equipment and to develop storage structures that involves in the long-term storage of grains with reduced storage loss. These traits are especially important when assessing long-term stored grains affected by insect infestations. In this research, Ponni rice grains that had been stored for a year were examined to identify alterations in physical properties and their interconnections under the stress of infestation. This research focuses on the study of the physical properties of the Ponni rice and correlation between different parameters. The results suggest a strong correlation among grain size parameters, whereas the shape descriptors exhibit a less pronounced relationship. Grasping these connections contributes to better milling efficiency, improved storage longevity, and enhanced market appeal of rice grains. These findings offer important perspectives for engineers, agronomists, and food processors seeking to optimize postharvest management and product quality.
