Complex Carbohydrates

Complex Carbohydrates Many monosaccharides linked together. Called polysaccharides. Found in grains, seeds, nuts, fruits, vegetables. Types include: Starches Cellulose Gums Pectins B-3.02 -- Complex Carbohydrates

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

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. B-3.02 -- Complex Carbohydrates

B-3.02 -- Complex Carbohydrates Starch Found in: Cereals/grains Corn Oats Wheat Rice Other plant foods Potatoes Beans/legumes B-3.02 -- Complex Carbohydrates

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-3.02 -- Complex Carbohydrates

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-3.02 -- Complex Carbohydrates

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 B-3.02 -- Complex Carbohydrates
