Aspartame CAS#22839-47-0
1. High Sweetness:
Aspartame is 150-200 times sweeter than sucrose, meaning only small amounts are required, making it cost-effective and efficient in sweetening products.
2. Pleasant Taste Profile:
It offers a pleasant, sweet flavor with no aftertaste, enhancing the taste of beverages and foods, especially citrus and fruity flavors.
3. Calorie Reduction & No Tooth Decay:
Aspartame helps reduce calorie intake and poses no risk of tooth decay, making it ideal for weight management and diabetic products.
4. Lower Toxicity:
Compared to other artificial sweeteners, aspartame has lower toxicity, providing a safer option for consumers.
Aspartame is a synthetic sweetener classified as an amino acid dipeptide derivative. First discovered in 1965 by chemists researching anti-ulcer medications, it offers several significant advantages: requiring only small quantities due to its intense sweetness (150-200 times sweeter than sucrose), delivering a pleasant taste profile, and enhancing citrus and other fruit flavors.
Additionally, it provides calorie reduction, poses no risk of tooth decay, and demonstrates lower toxicity compared to other artificial sweeteners like saccharin. These properties have led to its widespread use in beverages, diabetic food products, and various weight management supplements. Notably, aspartame was formerly a key ingredient in the formula of mainstream cola beverages.
