Productions Sugar Starches Complex Carbohydrates Types of Starches Granules Ways plants package starch not water soluble Amylopectin Branched (All which ways) Amylose linear Polymer Large molecules made of many smaller molecules • Simple Carbohydrates • Saccharides-name for all sugars organic compounds • All carbohydrates contain a hydroxyl group –OH • Types of Sugar • Monosaccharaides • Glucose • Fructose • Galactose • Mannose • Disaccharides • Sucrose • Lactose • Maltose • Alcohol
Chemical Structure Sugar Starch
Functions Sugar Starches Provide Structure Bind- holding two things together Thicken Gelatinization- starch is suspended in water Gelatinization Point- Maximum Swelling Extra 57.0. #1 Energy (Glucose) Bulk Lowers (Cholesterol) Burn fat • Sweeteners • Preservatives • Sugar helps prevent food spoilage • Tenderizers • When sugar is added to the dough it will tenderize the product • Crystallizing Agents • Linked to the solubility of a solute to dissolve in a solvent • Caramelizing Agents • When sugar is subjected to high or prolonged heat, it changes into a brown liquid • Fermenting Agents
Nutritional Implications Sugar Starches Digestible/indigestible- 4 cal. =1 gram Most abundant & most economical food science Extra Glucose Glycogen 2Hr of exercise then fat – all other stored as fat Fiber, Bran and Bulk Indigestible (cellulose) adds bulk, feed fall , aids in digestion lowers cholesterol aids in weight Ketosis Process at burning off fat w/o carbs damages kidneys, liver & etc. • Dental Carries • Or tooth decay caused by acid damaging the enamel coating on the teeth • Diabetes Mellitus • Is the body’s inability to move glucose from the bloodstream to the cells • Weight Gain
