“…Increasing the drop height is predicted to result in higher impact energy and stress cracking on the seeds, leading to increased damage (Delfan et al., 2023 ; Shahbazi & Shahbazi, 2023 ). Seed coat cracking is a quality concern in legumes such as chickpeas as well, where it may impact seed quality, vigor, and germination percentage (Wang et al., 2024 ; Wang & Cichy, 2023 ). This adverse effect has been observed in previous studies on corn seeds (Shahbazi & Shahbazi, 2022a ).…”

Impact damage is the most destructive effect on the seeds during harvesting, handling, and storage, both on‐farm and off‐farm. The chickpea seeds' dicotyledonous characteristics and large mass and size make them susceptible to mechanical damage under impact loading. Tests were conducted to determine the extent of damage to chickpea seeds due to the impact caused by free fall. The extent of internal damage to the chickpea seeds was determined, which included the measurement of seed deterioration by the accelerated aging method (percentage loss in germination in the accelerated aging test) and the measurement of electrical conductivity. Three independent variables were used in the test, namely: (a) drop height (3, 6, 9, and 12 m), (b) impact surface (concrete, metal, plywood and seeds on seeds), and (c) seed moisture content (10%, 15%, 20%, and 25% w.b). The results showed that drop height, impact surface, and moisture content had significant effects (p < .01) on the loss in germination percentage and change in electrical conductivity of chickpea seeds. In terms of loss in germination, the highest damage to seeds occurred at the metal impact surface (41.96%) and the least at the seed on the seed (29.71%). The highest amount of electrical conductivity was related to the seeds dropped on the metal (36.09 μS cm−1 g−1) and the lowest was related to seed‐on‐seed contact (21.68 μS cm−1 g−1). By increasing the drop height from 3 to 12 m, the loss in germination and electrical conductivity of seeds increased from 27.74% to 48.08% and from 18.72 to 40.47 μS cm−1 g−1, respectively. Increasing the moisture content of chickpea seeds from 10 to 25% causes a decrease in the amount of damage to the seeds in terms of electrical conductivity (from 38.40 to 21.18 μS cm−1 g−1), but increases the damage in the form of a loss in the percentage germination in the accelerated aging test (from 29.22% to 42.88%). To reduce the impact damage to peas caused by free fall, the height of the fall should be limited to about 6 m, and they should be prevented from hitting hard and rough surfaces.

“…The results were presented as SCC severity score and SCC rate. SCC severity score was calculated according to the severity of the SCC as described in a previous study (Wang & Cichy, 2023) and ranged from 1 to 5, where 1 = no seed coat damage and 5 = all seeds split . SCC rate indicated the percentage of seeds with SCC in the measured sample.…”

Dry beans are a nutrient‐dense food with a history of processing in metal cans to improve convenience for consumers. Flexible retort pouches have been gaining popularity as a food package to replace metal cans because they are lighter in weight and require less energy to process. While there are potential benefits of using pouches for processed bean products, a pilot‐scale pouch processing protocol for beans is needed for testing to expand to wider commercial applications. To address that need, the objectives of this study were to optimize a pouch processing method for dry beans and assess the subsequent quality of pouch‐processed beans. Black and kidney bean genotypes from different field trials and production years and harvested by different threshing methods were used in this study. Pouch processing was conducted with two types of pouches at a pilot facility, and processing quality included texture, appearance, and color. Cooking time of dry seeds was assessed to understand how variety and environmentally induced differences in cooking time influence pouch processing quality. Kidney beans that required longer dry seed cooking times had firmer texture when pouch processed (r = .72, p < .01). Both genotype and production year impacted cooking time and pouch processing quality. Threshing method had a significant impact on the appearance of processed kidney beans, while it had no significant impact on the processing quality of black beans. Pouch processing requires 42% (at 245°F/118.3°C retort temperature) or 60% (at 250°F/121°C) less retort processing time compared with canning. Both foil and non‐foil pouches can be used to differentiate varieties for processing quality, but the non‐foil pouches require much less effort to seal. This study provides a detailed methodology for pouch processing and quality evaluation of dry beans and useful information for researchers and processors in future applications of using pouches as alternative packaging for processed beans.

In this study, the Agricultural Research Center of Melkassa examined the performance of a laboratory loop type bean thresher. As a function of different drum speeds (450, 550, and 650 rpm), concave apertures (25, 35, and 45 mm), feed rates (550, 650, and 750 kg/h), and moisture levels (5, 10, and 15%), the extent of grain deterioration, threshing efficiency, and rate of implantation were examined. Utilizing response surface techniques, the experimental design for optimization was developed. The response variables were significantly impacted by each independent variable. With a cylinder speed increase of 7.5 to 10.83 ms-1 , the percentages of grain damaged, threshed, and germination decreased from 45.98 to 47.97%, 96.81 to 99.69%, and 85.75 to 55.98%, respectively. Despite an increase in seed germination, damaged grain and threshing efficiency decreased as the moisture content increased. Grain deterioration and threshing efficiency decreased, however seed sprouting improved in tandem with an increase in feed rate and convex aperture. The cylinder speed of 8.25 ms-1, the concave clearance of 37.4 mm, the feed rate of 672 kg/h, and the moisture content of 11.6% (db) were found to be the ideal parameters. In this case, the ideal ranges for seed sprouting, threshing efficiency, and grain impairment were found to be 3, 98.3, and 84.29%, respectively.
