1. Basic Information
Name: Aspartame
Alias: L-Aspartyl-L-phenylalanine methyl ester
CAS No.: 22839-47-0
Molecular Formula: C14H18N2O5
Molecular Weight: 294.30
2. Physical and Chemical Properties
Physical Properties
- Appearance: White crystalline powder
- Odor: Odorless, intense sweet taste, about 180–200 times sweeter than sucrose
- Solubility: Slightly soluble in cold water, soluble in hot water; sparingly soluble in ethanol; insoluble in fats, oils and non-polar solvents
- Melting Point: Decomposes at approximately 246–247 °C
- Specific Rotation: [α]D2? +14.5° ~ +16.0° (in dilute formic acid solution)
- Hygroscopicity: Slightly hygroscopic under high humidity
Chemical Properties
- Molecular Structure: Dipeptide methyl ester formed by L-aspartic acid and L-phenylalanine
- Hydrolysis Characteristics: Stable under neutral and weak acidic conditions; hydrolyzes under high temperature, strong acid or alkaline environment to produce aspartic acid, phenylalanine and methanol, losing sweetness
- Thermal Instability: Degrades rapidly above 120 °C, unsuitable for high-temperature baking and sterilization processes
- Photostability: Stable under indoor light; long-term exposure to strong UV light accelerates decomposition
- Maillard Reaction: The free amino group reacts with reducing sugars at high temperature to generate brown substances
- Compatibility: Compatible with most food raw materials, vitamins and common food additives; incompatible with strong alkalis, high-concentration oxidants and aldehydes
3. Main Application Fields
1. Food Sweetener (Core Application)
- Low-calorie sweetener for carbonated drinks, fruit juices, yogurt, chewing gum, candies and tabletop sweeteners
- Sugar substitute for low-sugar, zero-calorie functional food suitable for weight management and diabetic diet
2. Pharmaceutical Excipient
Sweetening agent for oral tablets, granules, syrups and pediatric medicines to mask bitter taste of active ingredients
3. Health Care Product Additive
Flavor improver for oral nutritional supplements, protein powder and solid beverages without extra calorie intake
4. Biochemical Reference Standard
HPLC calibration standard for dipeptide artificial sweetener detection in food inspection laboratories

Safety Warning
Approved safe food additive within legal dosage limits by global food safety authorities. Individuals with phenylketonuria (PKU) cannot metabolize phenylalanine and must avoid intake. Dust may mildly irritate eyes and respiratory tract during handling; wear dust mask and protective gloves in ventilated workspace. Do not apply to high-temperature processing procedures to prevent decomposition and loss of sweet taste. Store separately from acidic and alkaline raw materials.
