Bitter medicines are an important issue, especially for pediatric applications. As several APIs have bitter tasting components, high intensity sweeteners for taste optimization are of great interest. Join our webinar to discover our new sweetener toolbox enabling safe and stable formulations.
Mask bitter aftertaste for a sweeter pill to swallow! Patients’ compliance and the therapeutic benefit are supported by a pleasant taste of pharmaceutical formulations. With the high intensity sweeteners Neotame and Sucralose, you have efficient tools at hand which are superior to other sweeteners in many aspects:
• excellent sugar-like taste profile
• outstanding sweetness factors
• use effectiveness
• enhanced stability
We will present our new toolbox of two high performance sweeteners and focus on aspects of stability, safety, the application in various dosage forms, and market perception.
In this webinar, you will learn:
• How to optimize the patients' taste experience of your pharmaceuticals
• How sweeteners can be differentiated by their sensory profiles and features
• How our new product offering Neotame can be effectively used in your targeted formulations

for overall and aftertaste
sweetness and enables the
lowest overall bitterness.
The sensory profile of
Neotame is comparable to
that of Aspartame, but
Neotame is superior to

Information about stability
2 ways to ace the taste test
Stability is always dependent on pH, temperature and time
and the composition of your formulation and the API.
Neotame has superior
stability to aspartame*
and does not release
phenylalanine under
normal storage
conditions.
* May lose sweetness when heated; maillard type
reaction with primary amino group possible

EFSA Supporting publication 2021:EN-6918
Neotame
• Substance: stable in dry state during storage at 15 – 25°C;
passed 3 months accelerated stability test at 40°C
• Solid applications: supports heat treatment over short periods of time;
suitable for wet granulation
• Liquid applications: max. stability at pH 4.5
Sucralose
• Substance: stable during storage at 15° - 25°C, dry heat > 25°C to be avoided
• Solid applications: best stability at a water content of 0.5 – 2%
• Liquid applications: aqueous stability over a wide range of pH values

Neotame is superior to other sweeteners in many aspects
Proven safety
widely approved food additive: e.g. in USA (since 2002), EU (since 2010 / with E 961); safety evaluated by JECFA
No PKU warning label requested in difference to aspartame
suitable for individuals with phenylketonuria (PKU) and diabetes type 2 (zero glycemic index)
Excellent clean, sugar-like taste profile – can modify or mask bitterness
similar taste to that of sucrose, no bad aftertaste and good mouthfeel
Excellent stability
chemically stable under standard ambient conditions; more heat stable than Aspartame*
Cost-efficiency due to higher sweetness potency
by sweetness factor 8,000 to 13,000 greater than sucrose, 40-60 greater than Aspartame
Compatible with other sweeteners
such as sucralose, acesulfame, sucrose, and reducing sugars; synergistic effects possible in combination
* May lose sweetness when heated
15. • maximum potency per unit dose: 1.35 mg in powder, for solution (oral route)
Neotame is not considered new and may require a less extensive review the next time it
is included in a new drug product. Approved in a certain dosage form at a certain potency,
a sponsor could consider it safe for use in a similar manner for a similar type of product.
