Aspartame CAS：22839-47-0
Powerful Sweetening Effect:Aspartame delivers sweetness that is 150 to 200 times stronger than sucrose, allowing for much lower dosage levels while keeping production costs economical.
Excellent Sensory Qualities:It offers a pure, fresh sweet flavor with no unpleasant aftertaste, making it especially effective for boosting the taste of citrus and fruit‑flavored drinks and foods.
Tooth‑Friendly and Low‑Calorie Benefits:It helps reduce overall calorie intake and does not cause tooth decay, making it ideal for weight‑control products and items designed for people with diabetes.
Strong Safety Performance:It shows lower toxicity levels compared with many other artificial sweeteners, creating a reliable safety standard for use in consumer goods.
Aspartame is an artificially synthesized sweetener that belongs to the category of amino acid dipeptide derivatives. It was first discovered in 1965 in the course of medical research focused on developing anti-ulcer medications. This substance features many outstanding properties: it provides extremely strong sweetness—150 to 200 times that of sucrose—so only a very small amount is required in applications. It also offers a pleasant taste and effectively amplifies the flavor of citrus and various fruits.
