ABSTRACT

The geometric characteristics and mass-volume-area properties of haricot beans are essential for the design of equipment for harvesting, handling, drying, storing, dehulling, processing, and packaging. This study was carried out to determine the effect of variety on the geometric characteristics and mass-volume-area properties of four improved haricot beans varieties. The moisture content, 1000 seed mass, and true density of beans varied significantly (p < .05) in the range of 9–11.28%, 199.9–529.93 g, and 1127.52–1212.40 Kg/m³, respectively. The dimensional properties of the improved haricot bean were significant (p < .05) among the varieties, indicating that these would require some variation in the processing equipment design. Hydration capacity varied significantly from 0.14 to 0.36 g/seed among the improved haricot bean varieties. The hydration index also displayed significant differences among the varieties. Significant differences were observed in hydration coefficient and swelling capacity among the varieties and varied from 1.71% to 1.77% and 0.28 to 0.81 mL/seed, respectively.

摘要

扁豆的几何特征和质量-体积-面积特性对于收割、处理、干燥、储存、脱壳、加工和包装设备的设计至关重要。本研究旨在确定品种对四种改良扁豆品种的几何特征和质量-体积-面积特性的影响。豆类的水分含量、1000 粒种子质量和真密度分别在 9–11.28%、199.9–529.93 g 和 1127.52–1212.40 Kg/m ³范围内显着变化 ( p < .05) 。改良扁豆的尺寸特性显着（p< .05)，表明这些品种需要在加工设备设计上有所变化。改良扁豆品种的水合作用能力在 0.14 至 0.36 克/粒之间变化很大。水化指数也显示出不同品种之间的显着差异。不同品种之间的水合系数和溶胀能力存在显着差异，分别为 1.71% 至 1.77% 和 0.28 至 0.81 mL/种子。
