Study Notes

Gums and Mucilages

Gums are natural plant hydrocolloids that are anionic or non-ionic polysaccharides, readily dissolved in water, and are pathologic products.
Mucilages are physiologic products that form slimy masses with water.

Types of Gums

Tree or shrub exudate:
- Tragacanth is obtained from Astragalus gummifer (Fam. Leguminosae) and is commonly known as gum tragacanth.
- Karaya gum or sterculia gum
Marine gums:
- Algin is extracted from brown seaweeds by the use of dilute alkali, and its chief source is Macrocystis pyrifera (Fam. Lessoniaceae).
- Algin is a mucilage that forms a slimy mass with water.
Seed gums:
- Guar gum
- Others

Characteristics and Uses of Gums

Uses:
- Ingredients in dental and other adhesives
- Tablet binders
- Emulsifiers
- Gelating agents
- Suspending agents
- Stabilizers
- Thickeners
Algin uses:
- Suspending agent
- Food industry (ice cream, chocolate milk, salad dressing, icings, confectionery)
- Cosmetic preparations
- Sizing
- Other industrial purposes
Metabolism and caloric value of algin:
- Metabolized by the body
- Has a caloric value of approximately 1.4 calories per gram
