白色刀豆（Canavalia gladiata）种子由于其高蛋白质和碳水化合物含量而具有在加工食品制造中利用的潜力。我们以前的报告探讨了使用剑豆作为食品原料的来源，通过制备提取物在蒸馏水中。在本研究中，我们发现一种这样的提取物可以通过冷却凝胶化。通过煮沸并同时搅拌含有研磨豆的悬浮液来提取胶凝物质。凝胶提取物中几乎没有蛋白质。我们还研究了凝胶化发生的条件和凝胶熔化温度。提取物在低于10摄氏度的温度下凝胶化，而所得凝胶在高于65摄氏度的温度下熔化。这是第一次报道可以从刀豆中大量提取胶凝物质。我们期望这种胶凝剂可用于加工食品的生产。
White sword bean (Canavalia gladiata) seeds have the potential to be utilized in the manufacturing of processed foods owing to their high protein and carbohydrate content. Our previous reports explored the use of the sword bean as a source of food materials by preparing extracts in distilled water. In the present study, we found that one such extract can be gelated by cooling. The gelling substances were extracted by boiling and simultaneously stirring a suspension containing ground beans. Few proteins were present in the gelated extract. We also examined the conditions under which gelation occurred and the gel melting temperature. The extract gelated at temperatures below 10 degrees C, and the resulting gel melted at those above 65 degrees C. This is the first report that gelling substances can be extracted from sword beans in large quantities. We expect that this gelling agent can be used for the production of processed foods.
