gum (material) (organic material, <materials by composition>, ... Materials (hierarchy name)) |
|
Note: Carbohydrate containing exudates obtained from some trees or shrubs belonging to the family Fabaceae of the pea order Fabales. Gum is insoluble in alcohol and either soluble or swellable in water. Some plant gums are used in the form of water solutions in the manufacture of cosmetics, pharmaceuticals, and foods; when the water evaporates, a film having a considerable adhesive character is formed. Some gums, such as gum arabic, dissolve in water to give clear solutions. Other gums, such as gum tragacanth, form mucilages by the absorption of large amounts of water. May be distinguished from "resin" in that gum hardens in drying, but is usually soluble in water.

Additional Notes: |
|
| Chinese (traditional) ..... 含有取自某些蠶豆目豆科喬木或灌木之分泌物的碳水化合物，不溶於酒精，在水中可能溶解或膨脹。某些植物的膠以水溶液的形式被使用，以製作化妝品、藥物以及食品；當水份蒸發後，則形成黏著性極佳的薄膜。某些樹膠，例如阿拉伯樹膠，可溶解於水中而形成澄清溶液；其他的樹膠，例如黃耆膠，則藉由吸收大量的水份而形成膠漿。與「樹脂」的差別在於樹膠乾燥後會硬化，但通常可溶於水。 |
| Dutch ..... Gehard sap of afscheiding van verschillende bomen en struiken. |
| Spanish ..... Secreción viscosa que se obtiene de algunos árboles y arbustos y que se distingue de la "resina" porque se endurece al secarse, pero que es habitualmente soluble en agua. |
