Bauhinia is a leguminous plant species found in almost every part of the world, including southern Africa. In this study, grain composition and protein body microstructure of two indigenous southern African Bauhinia species, B. galpinii and B. petersiana were determined. Protein (38 g/100 g) and fat (23 g/100 g) were the major constituents of Bauhinia. Bauhinia grains also contained substantial amounts of zinc (6 mg/100 g) and iron (3 mg/100 g) when compared to FAO/WHO standards. The parenchyma cells of Bauhinia showed spherical protein bodies with globoids inclusions and these were surrounded by lipids. However, the protein bodies of B. petersiana were smaller in size (7 ± 3 μm) than those of B. galpinii (13 ± 4 μm). The microstructure of protein bodies in Bauhinia is very similar to that of soya, suggesting that the processing technology developed for soya protein may be adopted for Bauhinia.
紫荆是一种豆科植物，几乎在世界各地都有发现，包括南部非洲。在这项研究中，确定了两种南非本土紫荆（Bauhinia galpinii 和 B. petersiana）的谷物成分和蛋白体微观结构。蛋白（38 g/100 g）和脂肪（23 g/100 g）是紫荆的主要成分。与粮农组织/世卫组织标准相比，紫荆谷物还含有大量的锌（6 毫克/100 克）和铁（3 毫克/100 克）。紫荆的薄壁细胞显示出具有球形体蛋白的蛋白体和球体内含物，这些蛋白体被脂质包围。然而，B. petersiana 的蛋白体比 B. galpinii 的蛋白体小（7±3μm 比 13±4μm）。紫荆蛋白体的微观结构与大豆非常相似，这表明为大豆蛋白开发的加工技术可能适用于紫荆。
