Aspartame
Aspartame is a low-calorie artificial sweetener approximately 200 times sweeter than sucrose (table sugar). It is a methyl ester of the dipeptide composed of aspartic acid and phenylalanine. Due to its intense sweetness and low-calorie nature, aspartame is widely used as a sugar substitute in various food and beverage products. It is popular among consumers seeking to reduce caloric intake, especially diabetics and those on weight management programs. Aspartame breaks down at high temperatures, limiting its use in certain cooking or baking applications. It is approved by numerous global food safety authorities, including the FDA and EFSA.
Description

- Added to sugar-free chewing gums, candies, and breath mints.
- Used in powdered drink mixes and tabletop sweeteners.
- Incorporated in low-calorie desserts like sugar-free yogurts, ice creams, and puddings.
- Used in baked goods, though less heat-stable than other sweeteners (mainly in low-heat applications).
Pharmaceuticals
- Added to chewable tablets, syrups, and vitamins to improve taste without adding calories.
- Used in diabetic-friendly formulations.
Personal Care Products
- Incorporated into toothpaste and mouthwashes as a sweetening agent without promoting tooth decay.
Secondary Uses
Dietary Supplements
- Utilized in protein shakes, meal replacements, and vitamin powders.
Animal Feed
- Occasionally used in palatable veterinary formulations for flavor enhancement.
Industrial Uses
- Used in certain biotechnological applications where sweetness is required but caloric input must be minimized.
Food Packaging
- Incorporated in oxygen scavenging systems to preserve freshness indirectly by reducing microbial growth (less common).
