1. Complex Carbohydrates

2. Complex Carbohydrates
Many monosaccharides linked together.
Called polysaccharides.
Found in grains, seeds, nuts, fruits, vegetables.
Types include:
Starches
Cellulose
Gums
Pectins
B Complex Carbohydrates

3. B-3.02 -- Complex Carbohydrates
Starch
Most abundant complex carbohydrate
Many glucose units bonded together
B Complex Carbohydrates

4. B-3.02 -- Complex Carbohydrates
Types of Starch
Two basic structures in plant
Amylose
Linear
Found in wheat and corn
Amylopectin
Branched
Found in roots and tubers
Most foods have a combination of both.
Ratio affects the way the starch functions in food.

Found in:
Cereals/grains
Corn
Oats
Wheat
Rice
Other plant foods
Potatoes
Beans/legumes
B Complex Carbohydrates

6. B-3.02 -- Complex Carbohydrates
Cellulose
Many glucose units bonded together
Beta () bonds
Insoluble fiber
Forms rigid structure of plants
Provides texture in fruits and vegetables
B Complex Carbohydrates

7. B-3.02 -- Complex Carbohydrates
Gums
Soluble fiber
Function:
Thicken and stabilize mixtures
Trap flavor and color
Examples:
Salad dressings
Ice cream
Gummy bears
B Complex Carbohydrates

8. B-3.02 -- Complex Carbohydrates
Pectins
Soluble fiber
Naturally occurring in fruits
Amount depends on ripeness of fruit
Decrease ripeness, increase pectin
Produce strong gels, such as jams and jellies
