Aspartame is an artificial sweetener sold in the market. It consists of amino acids and provides calories like other amino acids. Yet, it is used as a low-calorie sweetening agent in food items. What is the basis of this use?
- A Aspartame is as sweet as table sugar, but unlike table sugar, it is not readily oxidized in human body due to lack of requisite enzymes
- B When aspartame is used in food processing, the sweet taste remains, but it becomes resistant to oxidation
- C Aspartame is as sweet as sugar, but after ingestion into the body, it is converted into metabolites that yield no calories
- D Aspartame is several times sweeter than table sugar, hence food items made with small quantities of aspartame yield fewer calories on oxidation ✓
✓ Correct answer: (D)
