Aspartame (E951) is a globally recognized high-intensity, low-calorie sweetener essential for modern food and pharmaceutical formulations. As a dipeptide of the amino acids L-aspartic acid and L-phenylalanine, it provides a clean, sugar-like taste without the caloric content, making it the ideal choice for brands developing sugar-reduced or sugar-free products. Our Aspartame is engineered for superior performance, offering excellent solubility and a consistent flavor profile that meets the exacting demands of today’s consumers.
Our Aspartame powder is guaranteed to meet the highest industry standards. Each batch is rigorously tested to ensure it conforms to the following specifications.
