MATCH notions to the specific Nutritive or Alternative Sweetener Sugar Alcohols Brown Sugar Aspartame Saccharin Sucralose Stevia Table Sugar High Fructose Corn Syrup Honey 1. Nutritive Sweetener made from corn starch that has been enzymatically converted to contain higher amounts of fructose. 2. Alternative sweetener, often used in baking, that is made by adding 3 chlorine molecules to sucrose. It cannot not be digested and absorbed 3. Nutritive Sweetener from plant nectar that has been converted by bee enzymes. 4. Alternative sweetener made from two amino acids and methanol that is not heat stable. 5. Nutritive Sweetener with a chemical structure that resembles sugar and alcohol and releases about 2.6 kilocalories per gram. 6. Nutritive Sweetener made from sugar cane or sugar beets. 7. Alternative sweetener made from a South American Plant that is Generally Recognized as Safe (GRAS) 8. Sucrose that contains molasses not removed during processing. 9. The oldest alternative sweetener on the market with an acceptable daily intake (ADI) of 5 mg per kilogram body weight per day.

Lab 13 - Sugars and Starches Exercise 1 Data Table 1: Sugar Tests with Benedict's Reagent Test Tube Number Substance Prediction Final Color Test Results for Reducing Sugar 1 Distilled Water 2 Glucose Solution 3 Starch Solution 4 Table Sugar 5 Splenda® 6 Sweet'N Low® 7 Milk 8 Juice 9 Potato 1. Did the table sugar solution test positive or negative for reducing sugars? Explain the science behind your results. 2. Do Splenda® and Sweet'N Low® test positive or negative for reducing sugars? List the ingredients found in each of these products. Underline the ingredient that is the artificial sweetener. (Hint: There is only one artificial sweetener in each of the products. Refer to the background as needed.) 3. What is the relationship of glucose and dextrose? How does this relationship influence the test results for Splenda® and Sweet'N Low®? 4. A common artificial sweetener found in Equal®, NutraSweet®, and many diet sodas is aspartame (C14H18N2O5). Would a sample of pure aspartame test positive or negative for reducing sugars? (The pure sample does not contain other ingredients, such as dextrose, maltodextrin, or calcium silicate.)
7. Conduct some research (from reputable, primary or secondary sources!) on the structure of another type of artificial sweetener: a. What is the structural difference between sucrose (table sugar) and sucralose? Briefly describe the reaction that synthesizes sucralose from sucrose. (4 marks) b. Is sucralose a polar molecule? Explain. (2 marks) c. What properties of sucralose make it a good sugar substitute? Why does it sweeten food without spiking blood-sugar levels? Why does it have a low caloric value? (4 marks) d. List and explain at least three adverse effects of excessive sucralose consumption. (3 marks)
