“…Celik, et al [44] reported that the weight loss of apple fruit increased with the prolongation of storage time and fruit damage. Mir and Shahbazi [15] and Tao, et al [45] reported similar results. The results of this study showed that the 'Shine Muscat' grapes' weight loss was greater in the compression treatment groups compared to the control group.…”

“…Xu, et al [14] discovered that fall impact had a significant impact on the physiological response of apples, reducing the storage life and commodity value of postharvest apples significantly. Mir and Shahbazi [15] observed that vibration frequency is a significant factor affecting persimmon vibration damage, resulting in the deterioration of the physical, mechanical, and chemical properties of persimmon. The aforementioned findings have significant practical implications for alleviating fruit loss as well as preserving fruit commodity value, which additionally offer an achievable way of developing or enhancing fruit postharvest treatment technology [16].…”

Mechanical stress induced by compression during preharvest and postharvest handling of fresh fruit is a major factor influencing the quality of fresh fruit. The degree of compression primarily governs the extent of quality deterioration. However, research on the damage mechanisms of mechanical compression in table grapes remains scarce. This investigation evaluated the impact of varying compression levels (0%, 20%, 40%, 60%, and 80%) on the postharvest quality attributes of table grapes. Changes in postharvest physical properties (overall appearance and color), structural properties (firmness, springiness, cohesiveness, and chewiness), physiological qualities (total soluble solids, titratable acidity, ascorbic acid, malonaldehyde content, and relative electrical conductivity), and cell microstructure of the berries was determined at 4 °C during 15 d of storage. Mechanical compression contributed to the deterioration of the quality of table grapes during storage, resulting in increased weight loss, decay rate, malonaldehyde content, and relative electrical conductivity; and decreased total soluble solids, titratable acidity, and ascorbic acid content. Furthermore, as compared to the control group, mechanical compression resulted in substantial yellowing and diminished textural qualities of grapes. In particular, compression treatment caused significant deformation of grape cell microstructure. In conclusion, mechanical compression stress significantly affects the physical and physiological properties of postharvest table grapes, as well as the internal cellular organization. As compression levels increase, the quality of table grapes progressively deteriorates, leading to a substantial reduction in storage life and commercial value. This study offers essential information for devising damage prevention strategies in preharvest and postharvest handling of table grapes.

“…One of the most important factors that affects the grain quality of agricultural products is mechanical damage to the grains (seeds). Mechanical injuries can be caused by any type of physical and mechanical action, but injuries caused by the impact of the moving parts of machines during harvesting and postharvest processing are the most serious ones (Shahbazi, 2011;Mir and Shahbazi, 2022). The seeds of agricultural products are constantly subjected to impact forces from machines from the moment they are harvested to the time they are transferred into storage (Shahbazi et al, 2011a;2011b;2011c;Shahbazi et al, 2012).…”

The study aimed to determine the extent of the percentage of mechanical damage (seed breakage) to chickpea seeds due to the impact caused by free fall. Three independent variables were used in the test, namely: impact surface (concrete, metal, plywood and seed-on-seed), drop height (3, 6, 9, and 12 m) and seed moisture content (10, 15, 20, and 25% w.b.). The results showed that all three independent variables significantly influenced the percentage breakage of chickpea seeds. The seeds dropped onto concrete and metal had by a significant margin the highest means of percentage breakage at 13.89 and 12.94%, respectively, in comparison with 10.64 and 8.34% on plywood and in the case of seed to seed impact, respectively. Increasing the drop height from 3 to 12 m caused a significant increase in the mean values of damage to seeds from 7.20 to 15.57%. Increasing the moisture levels caused a decreasing trend by a factor of two in the damage to the seeds due to free fall. Empirical models were developed to reveal the relationships between damage to chickpea seeds with various moisture contents that was due to the impact with different impact surfaces caused by free fall from the drop height.K e y w o r d s: chickpea, mechanical damage, handling, drop height, contact surface
