[Concept map: ‘Xanthan gum’ in the centre with six empty boxes joined to it.]
Best answer
Answer: Uses of xanthan gum (six boxes) — (1) production of pigments, (2) fertilizers, (3) weedicides, (4) textile pigments, (5) toothpastes, (6) high-quality paper.
Xanthan gum is obtained by fermentation of starch and molasses with the help of Xanthomonas species. Because it dissolves in both hot and cold water and has high density, it is useful in many industries. As per the textbook it is used for the production of pigments, fertilizers, weedicides, textile pigments, toothpastes and high-quality paper.
(It is also used as a thickener in food items such as ice creams, puddings, milk shakes and instant soups, which may be accepted as an additional use.)
