Physical, mechanical and chemical properties of pomegranate fruits

This work focuses on studying the physical, mechanical and chemical characteristics of pomegranate fruits (Manfaloty and Wonderful varieties), to be used in the design and development of specific machine and their operations. The length, width and thickness of pomegranate fruits were 7.31 and 7.53, 6.85 and 7.20 and 6.67 and 6.20 cm, respectively, for Manfaloty and Wonderful varieties. The geometric mean diameter and arithmetic mean diameter of the pomegranate fruits were 6.92 and 6.94 and 7.21 and 7.22 cm, respectively, for Manfaloty and Wonderful varieties. The pomegranate fruits mass was 279.55 and 306.01 g for Manfaloty and Wonderful varieties, respectively. The volume of fruits was 276.12 and 288.51 cm3 for Manfaloty and Wonderful varieties, respectively. The true and bulk densities of the pomegranate fruits were 1012.42 and 921.51 and 1060.66 and 927.08 kg m-3 for Manfaloty and Wonderful varieties, respectively. The moisture content of pomegranate fruit was 84.37 and 86.01 % for Manfaloty and Wonderful varieties, respectively. The repose angle of pomegranate fruits was 41.33 and 43.07 for Manfaloty and Wonderful varieties, respectively. The cutting force and crushing force of pomegranate fruits were 23.72 and 27.26 and 25.80 and 26.64 kg for Manfaloty and Wonderful varieties, respectively. The firmness of pomegranate fruits was 46.45 and 47.99% for Manfaloty and Wonderful varieties, respectively. The total soluble solids (TSS) of pomegranate fruits were 15.17 and 16.09 % for Manfaloty and Wonderful varieties, respectively.
