Overview
Neotame is an artificial sweetener developed as a derivative of aspartame but with significantly higher sweetness and stability. It was approved by the FDA in 2002 and is used globally as a sugar substitute in low-calorie and diabetic-friendly products. Unlike aspartame, neotame is not metabolized into phenylalanine, making it safe for individuals with phenylketonuria (PKU). Its intense sweetness allows for minimal usage, reducing production costs and caloric content in end products.
Physical and Chemical Properties
Neotame is a white, odorless crystalline powder with a sweetness potency 7,000–13,000 times that of sucrose. It is stable under high temperatures (up to 100°C), making it suitable for baked goods and pasteurized beverages. Its solubility in water and ethanol facilitates incorporation into liquid and solid formulations. The compound’s ester bond resists hydrolysis, ensuring prolonged shelf life without degradation.
Main Applications
Neotame is extensively used in the food and beverage industry, including soft drinks, dairy products, candies, and chewing gum. It synergizes with other sweeteners like sucralose to mask bitter aftertastes. In pharmaceuticals, it sweetens syrups and chewable tablets without affecting drug stability. Its non-cariogenic property also makes it ideal for oral care products like toothpaste and mouthwash.
Safety and Storage
Neotame is classified as GRAS by the FDA and JECFA, with an acceptable daily intake (ADI) of 0.3 mg/kg. It does not require PKU warnings, unlike aspartame. Storage recommendations include airtight containers in cool, dry conditions (below 25°C) to prevent clumping or moisture absorption. Bulk quantities should be palletized to avoid compaction.
B2B Procurement Guide
Buyers should prioritize suppliers with ISO 9001 or FSSC 22000 certifications to ensure quality and traceability. Request Certificates of Analysis (CoA) for each batch, verifying purity (≥97%) and heavy metal content. Consider regional regulations; for example, the EU requires E-number labeling (E961). Negotiate bulk discounts for orders above 100 kg, but confirm shelf life (typically 24 months unopened).
